The left box cover, the right box cover, the front box cover and the rear box cover are collectively called box covers, and the left box bottom, the right box bottom, the front box bottom and the rear box bottom are collectively called box bottoms. For ease of folding, it is assumed that all of the box panels are of equal wall thickness. The box bottoms of the left box cover and the right box cover are divided into two halves according to the width dimension of the box, and the length of the box is equal to the length dimension of the box; the box bottoms of the front box cover and the rear box cover are divided into two halves according to the length dimension of the box, the width is equal to the width dimension of the box, and two wall thickness dimensions are subtracted, namely two wide side surfaces of the box bottoms of the front box cover and the rear box cover are positioned in the box. The box cover and the box bottom are provided with an inner layer and an outer layer, the front box cover and the rear box cover are the inner layers, and the left box cover and the right box cover are the outer layers.

The reverse folding is to select a vertical box plate to be cut along a vertical line, turn over and fold the vertical box plate, and after the vertical box plate is folded, the inside faces outwards and the outside faces inwards. This is called reverse folding, as opposed to the normal direct crush folding.

The two U-shaped pieces of the double-hole elbow comprise a double-hole connecting piece which can rotate, and the other double-hole is fixed and called an elbow U-shaped piece; the U-shaped parts at the upper and lower ends are called long transverse U-shaped parts. The U-shaped parts at the two sides of the wide box plate are called wide vertical U-shaped parts, and the U-shaped parts at the upper and lower ends are called wide transverse U-shaped parts. The U-shaped parts at the bottoms of the left box cover and the right box cover are called long-cover U-shaped parts, and the U-shaped parts at the bottoms of the front box cover and the rear box cover are called wide-cover U-shaped parts. The eight U-shaped parts are collectively called U-shaped parts. For the purpose of distinguishing from the double-hole elbow U-shaped piece and the elbow U-shaped piece, the other six U-shaped pieces are also called flat U-shaped pieces. Typically the long cross U-shaped member mates with the long cover U-shaped member in pairs and the wide cross U-shaped member mates with the wide cover U-shaped member in pairs. The vertically mounted shaft is called a vertical shaft, and the horizontally mounted shaft is called a horizontal shaft.

The soft box plates are sealed and blocked by edge sealing pieces on two side edges of the box bottom of the box cover, and the soft box plates are sealed and blocked by edge locking pieces at the opening part of the box bottom of the box cover and male and female horizontal climbing buckles are installed.

In the double holes of the double-hole connecting piece, a hole capable of swinging is called a movable hole, the other hole which is matched with the round hole of the flat U-shaped piece into a concentric circle by adopting an equidistant concave-convex alternate structure is called a fixed hole, a vertical shaft penetrates through the hole of the concentric circle, the double-hole connecting piece and the flat U-shaped piece are connected into a whole to form a double-hole elbow U-shaped piece, and the double-hole connecting piece can swing around the vertical shaft within the range of 0-180 degrees; the double-hole connecting piece and the flat U-shaped piece form a 90-degree right-angle position, the two pieces are solidified into a whole, the elbow U-shaped piece is formed by removing the back plate, and the position of the double holes is kept unchanged. The Y-shaped structures at the two ends of the length of the U-shaped piece, the edge locking piece, the long groove U-shaped piece, the edge sealing piece and the square hole edge sealing piece are provided with 45-degree bevel edges and positioning buckles with complementary concave and convex shapes on the bevel edges. The long box plate uses an elbow U-shaped piece and three flat U-shaped pieces, the long box plate of the reverse folding box uses a double-hole elbow U-shaped piece and three flat U-shaped pieces, the wide box plate uses four flat U-shaped pieces, each box cover and box bottom use a lock edge piece, a flat U-shaped piece and two edge sealing pieces, the front box cover and the rear box cover without flat climbing buckles use two edge sealing pieces, a long groove U-shaped piece and a flat U-shaped piece, and the box plate of the telescopic front box cover and the rear box cover and box bottom use two edge sealing pieces, a square hole edge sealing piece and a flat U-shaped piece. The inner and outer panels at the peripheral edges of the soft box board are respectively pressed in grooves at two sides of the Y shape by a 90-degree pressing plate with riveting holes and inclined planes and a straight pressing plate and are riveted and fixed by rivets. The 90-degree pressure plate is arranged at the 45-degree bevel edge butt joint part of the frame and mainly connects the two Y-shaped parts at the bevel edge into a whole. In order to strengthen the stability of the frame, a double-head Y-shaped part and a double-inclined pressing plate can be additionally arranged in the transverse and vertical directions of the frame to be used as a strengthening and supporting rib plate. Every boxboard pairs according to the mutual position relation in the case, pair in two U-shaped pieces that need link together on the boxboard, long, the pairing U-shaped piece between the wide boxboard adopts the unsmooth alternate structure of equidistance of replacing the crescent moon, and the round hole of two U-shaped pieces is mutually supported to be concentric round hole, and concave section bottom unilateral has the crescent moon, can prevent to match protruding section and rotate to crescent moon one side. So that the two U-shaped parts can rotate relatively around the same shaft within the range of 0-90 degrees. Because the relative rotation range of the connected long box plate and the wide box plate is 0-90 degrees when the box is unfolded and folded. The matched U-shaped pieces between the box cover bottom and the long and wide box plates adopt an equidistant concave-convex alternate structure, the round holes of the two U-shaped pieces are matched into concentric round holes, and the two U-shaped pieces can relatively rotate around the same shaft within the range of 0-180 degrees because the bottom of the concave section does not have a crescent. Because the angle of the box cover and the box bottom when the box cover and the box bottom are opened is equal to or larger than 180 degrees. Each pair of U-shaped members are connected in series by a shaft to form a box with twelve box plates.

The flat U-shaped piece is formed by combining a U shape and a Y shape when viewed from the cross section, the shape of the U shape is similar to the U shape, the opening of the U shape is sealed by a transverse plate, the U shape is called a flat opening part, and a concentric round hole is added in the semicircle of the U shape to form the U shape. The double-hole connecting piece is formed by splicing two U-shaped flat openings together and then splicing a back plate. The Y shape is that two inclined planes which symmetrically extend to the left and right are arranged at the top of the head of a vertical plate, and the top end of each inclined plane is provided with a short vertical plate. The vertical plate is similar to a vertical line on the middle-lower half part of the Y, and the two symmetrical inclined planes are similar to the upper half part of the Y. The lower end of the Y shape is vertical to the flat opening part of the U shape to form a flat U-shaped part. And a flat plate vertical to the tail of the Y shape is added at the lowest end of the Y shape to form the edge sealing piece. A long vertical plate is additionally arranged at one tail end of the edge sealing piece flat plate downwards, and a plurality of small flat plates in the same direction as the flat plate are additionally arranged at the middle parts of the long vertical plates and the lowest ends of the long vertical plates to form the edge sealing piece due to the fact that the long vertical plate is too long. The number of smaller plates will depend on the material used and the particular size of the long riser. The small flat plate has the functions of reducing the buckling deformation of the long vertical plate and reinforcing ribs; secondly, the two serging pieces can support each other when buckled, and thirdly, dust and sundries are sealed.

The edge sealing pieces are arranged on two side edges of the box bottom of the box cover for plugging and reinforcing the soft box plate. The locking edge part is provided with a plurality of positioning clamping grooves for mounting male and female buckles, and the Y-shaped clamping grooves are provided with flat plate parts vertical to the tail parts. The number of the positioning clamping grooves is determined according to the number of the male buckles and the female buckles required for sealing the box. The side of the two lock edge pieces with the small flat plates is oppositely buckled at the opening part of the box and used in pairs. One piece is provided with a male buckle, and the other piece is provided with a female buckle. The lock edge piece is connected with the soft box plate of the interface part and is also fixed with the male buckle and the female buckle. A male buckle and a female buckle are respectively arranged in a serging piece at the bottom of the box cover, and the male buckle and the female buckle are fixed in a Y-shaped riveting hole at the positioning clamping groove by rivets. The box bottom of the box cover is sealed after the male buckle and the female buckle are buckled, and the box cover can not be opened without being pried.

The male buckle and the female buckle are called as a horizontal climbing buckle, the male buckle is provided with two symmetrical clamping jaws, each clamping jaw consists of a buckle head and two bent clamping arms formed by 90-degree turning, the structure is similar to a T shape, the buckle head is arranged on the top of the buckle head in a horizontal direction, and the bent clamping arms are represented by the vertical direction. The structure that the bent clamping arm is a male buckle and a female buckle is harmoniously and symmetrically adopted; and secondly, a vacant position is made for the U-shaped buckle of the buckle pressing plate. The structure of the male buckle is symmetrically distributed along the center line between the left surface and the right surface, the bottom lug boss of the buckle head is the lower buckle hook, and the leftmost lug boss and the rightmost lug boss on the two buckle heads are the left spring bolt and the right spring bolt. The part of the buckle head, which is positioned on the outer side surface of the clamping arm, is an upper buckle, and the upper buckle comprises a lock tongue. A step is arranged between the lock tongue and the top surface of the button head, and is called as a locking platform. A step is arranged between the bottom surface of the lock tongue and the bottom surface of the lower clasp, and the step is called as a sliding stopping table. The lower clasp and the upper clasp are just like the claw of the claw, and the function of the lower clasp and the upper clasp are to hook the lower clasp table and the upper clasp table of the female clasp body. The surface of the buckle head connected with the clamping arm is a hooking surface, and when the male buckle and the female buckle are buckled, the hooking surface is contacted and attached with the buckling surface of the female buckle. The left and right opposite inclined surfaces on the two buckles are pushed inclined surfaces, and the inclined angle of the pushed inclined surfaces is less than 12 degrees. The root of card arm and pin thread body unite, and the root of two card arms respectively has a vertical logical groove of narrow and long, two little inclined plane platforms and a little breach in the middle of towards the central line direction. The tail part of the male buckle body has the same structure as that of the female buckle body, and is a U-shaped through groove which is formed by two similar straight pressing plates and is provided with a riveting hole and an inclined plane. The bevel is the same as that of the pressing plate, and is used for pressing the inner edge part and the outer edge part of the soft box plate together with the Y-shaped bevel.

The female buckle is formed by combining a female buckle body and a buckling and pressing plate into a whole through a buckling shaft, and the buckling and pressing plate can swing around the buckling shaft within a certain angle range so as to realize actions of buckling, unbuckling and abdicating. The structure of the female buckle body is divided into a front part, a middle part and a tail part which are symmetrically arranged along a central line between the left side and the right side, and the shape of the female buckle body is a positive-length fractal structure when viewed from the front. The middle part is a cross-shaped through hole, the top end of the cross shape is provided with a abdication inclined plane, the middle part of a small square through hole at the upper part of the cross shape is provided with a buckling shaft through hole vertical to the left and right surfaces, a long through groove at the middle part of the cross shape is a sliding groove, wide surfaces at two ends of the length of the sliding groove are sliding stop surfaces, the through holes on a platform at the top of the sliding stop surfaces are a left locking hole and a right locking hole, the hole walls of the locking holes are closed, a long vertical surface close to the front end in the sliding groove is a lower buckling platform, and a left rectangular table column and a right rectangular table column which rise along the lower buckling platform are a left upper buckling platform and a right upper buckling platform. When the male buckle and the female buckle are hooked, the lower buckle platform is attached to the lower buckle, and the upper buckle platform is attached to the upper buckle. Namely, the common surface where the lower buckling platform, the left upper buckling platform and the right upper buckling platform are located is the buckling surface of the female buckle. The upper parts of the left and right upper buckling tables are provided with pressing tables extending towards the center, the length of each pressing table is slightly smaller than the swing distance of the clamping arm, and the space below each pressing table can accommodate the swing of the clamping arm. The pressing table is mainly used for assisting the lock hole to press the clamping arm, preventing the clamping arm from prying due to bumping to damage the stability of the pressing plate and playing a role in paying the lock hole. The vertical face that lockhole upper portion faced inwards is the locking face promptly, and the meaning of locking face is that, when the spring bolt slided into to the lockhole, the spring bolt just stopped sliding after the locking face is touched to the locking platform. The locking surface is also the starting surface of the lock hole extending leftwards and rightwards. When the button head slides left and right in the sliding groove, the sliding stop table of the lower button hook touches the sliding stop surface, and the sliding is stopped. The short through groove at the lower end of the cross shape is used for the abdication of the double-inclined plane boss on the buckling and pressing plate during swinging. The front part of the female buckle body is a front platform which extends from the bottom surface and is provided with an abdicating notch. The yielding notch is a vacancy which is given for the bottom of the U-shaped buckle on the buckling plate, and the size of the yielding notch is suitable for not hindering the normal work of the U-shaped buckle. The front platform is used for providing support for a pair of clamping arms of the male buckle during buckling and controlling the distance between the male buckle and the female buckle.

The structure of the buckling plate is symmetrically distributed along the center line between the left surface and the right surface, and the pressing plate is a body of the buckling plate and integrates the front part, the middle part and the tail part. The front end is a long notch with a U-shaped buckle, the U-shaped buckle consists of a fixed hook and a movable hook, the fixed hook is connected with the back of the panel of the buckling plate into a whole, the outer side of the movable hook is provided with a buckle tooth, the middle part of the buckle tooth is provided with a notch opposite to the position of a small notch in the male buckle, and a slightly convex vertical platform is arranged in the notch. This arrangement provides access for inserting tools when prying the press plate and protects the button teeth from damage. The movable hook has certain elasticity and can swing under the action of external force. And a spacing distance is arranged between the two ends of the U-shaped buckle and the long notch. The plate plane area of the pressing plate is large, and the pressing plate is used for shielding the buckled clamping arm. The middle part is mainly a double-inclined-plane boss consisting of two main push inclined planes, and the main push inclined planes are symmetrically arranged on the left side and the right side of the double-inclined-plane boss. The left side buckle and the right side buckle are mutually offset by the counterforce generated by pushing the inclined plane, so that the buckling and pressing plate is prevented from being inclined due to the counterforce. One of the designs of the main push inclined plane and the pushed inclined plane is good in force increasing effect, so that the buckling plate is easy and labor-saving to press; the oblique angles of the main pushing oblique plane and the pushed oblique plane are equal and less than 12 degrees, and the self-locking function is realized; the clamp arm always has the counterforce of resilience, but the buckling system is kept stable due to the self-locking function of the inclined plane; and thirdly, the downward vertical pressing of the buckling plate is converted into the left and right horizontal sliding of the two buckling heads. The tail part of the buckling and pressing plate is of a concentric circular structure, and a buckling shaft can penetrate through the hole of the concentric circular structure.

When the male buckle is buckled, the two symmetrical main push inclined planes on the buckling plate push the pushed inclined planes of the two buckling heads, so that the two buckling heads slide to the left side and the right side simultaneously until the spring bolt enters the lock hole, one part of the width of the clamping arm enters the lower surface of the pressing table, and when the buckling teeth of the U-shaped buckle of the buckling plate enter the lower surface of the small inclined plane platform of the male buckle, the buckling plate is clamped, and the horizontal climbing buckle enters a locking state. Because the male and female hooks are combined together at this time, the buckling teeth can not retreat to release.

When the empty box or the box is not full of articles, the opening of the box cover is easy to collapse, so that the horizontal climbing buckle is inconvenient. A set of self-balancing device is added to the horizontal climbing buckle, so that the horizontal climbing buckle is automatically balanced after being buckled.

The specific method is that two narrow rectangular bodies are additionally arranged on the planes of the left side and the right side of the front platform of the female buckle body, and the narrow rectangular bodies are longer than the front platform. And a sunken step is dug out on the outer sides of the two clamping arms of the male buckle body, and the thickness dimension of the sunken step is equal to that of the front platform. The length of the sunken step is larger than the difference between the lengths of the narrow rectangular body and the front platform, and mainly avoids the interference phenomenon during buckling. In order that the sunken steps do not influence the swing of the clamping arm, a narrow and long vertical through groove is also arranged between the sunken steps and the clamping arm.

After the buckle is horizontally climbed, the bottom surfaces of the pair of clamping arms are pressed on the surface of the front platform, the narrow rectangular bodies on the two sides of the front platform are pressed on the sunken step surfaces on the outer sides of the two clamping arms, the two clamping arms are mutually supported and mutually pressed to achieve self balance, and the opening part of the box cover cannot collapse. Both sides of the horizontal climbing buckle are provided with self-balancing devices, so that the phenomenon of stress deflection possibly occurs due to the fact that the horizontal climbing buckle is arranged on one side is avoided.

The horizontal climbing buckle provided with the self-balancing device is called a self-balancing horizontal climbing buckle. The female buckle body is called a self-balancing female buckle body, and the male buckle is called a self-balancing male buckle.

When the vertical and horizontal climbing buckle is buckled or opened on the bottom plane of the heat-insulation cone plate, the problem of collapse does not exist, and therefore a self-balancing device is not arranged.

The length of general case, wide size differ great, if preceding, back case lid bottom of the case also need climb with the level and detain the lock, then after the case is folding, preceding, back boxboard will be than left and right case lid and grow out a lot, probably influence the pile up neatly. Because the front box board and the rear box board are arranged in the inner layer of the box, the box bottom of the front box cover and the rear box cover or the telescopic box board structure without horizontal climbing buckles can be adopted for remedying.

In the bottom of front and back box covers without horizontal climbing buckle, long U-shaped part is used to replace the lock edge part at the mouth of the box plate to plug and connect the soft box plate at the mouth. The U-shaped part of the long groove U-shaped part is provided with a plurality of pairs of grooves and narrow rectangular through holes, a thin rectangular body is arranged between the bottom of each groove and the corresponding narrow rectangular through hole, and the middle part of the thin rectangular body can deform and yield towards the direction of the narrow rectangular through hole after being pressed. Straight buckle teeth are arranged in the grooves and are connected in series by a shaft. The structure of the straight buckle tooth is similar to that of a square vertical tooth with a cone at the top part added at the flat opening part of the U shape. The radius of the U-shaped arc is R1, and the distance between the bottom surface of the groove and the center of the straight-buckled tooth is also equal to R1. A section of width is taken at the middle part of the length of the straight buckle tooth, a semi-circular body with the radius of R2 is additionally arranged, R2 is larger than R1, a vertical surface and a top plane which are tangent with R1 are arranged on the left side of the straight buckle tooth and the arc top of the R1, and a vertical surface which is tangent with R2 is additionally arranged on the right side. When the left vertical surface and the top plane are positioned at the bottom of the groove, the thin cuboid can be pressed to deform by using point force under the action of R2, and the straight buckle tooth is pulled. This arrangement is primarily to prevent free swinging of the spur toothing up and down the groove of the elongated U-shaped member. The vertical surface added on the right side is mainly used for preventing the straight buckle teeth from being reversely pulled.

A long hole Y-shaped piece and a long hole pressing plate which are used for replacing a rectangular hole through groove are arranged at the superposition position of the box bottoms of the left box cover and the right box cover and square vertical teeth of straight buckle teeth erected in the grooves of the long groove U-shaped piece, and the square vertical teeth can be inserted into the rectangular hole through groove. The double-inclined pressing plate positioned on the outer surface of the box plate is not provided with a long hole. Therefore, the combination of the square vertical teeth and the rectangular through grooves can also pull the wide box plate, and the outward bulging and explosion of the box plate are avoided. After the straight buckle teeth are leveled, the box can be conveniently folded and stacked.

The box bottoms of the front box cover and the rear box cover without the parallel climbing buckle are only inserted and combined with the long hole Y-shaped pieces on the box bottoms of the left box cover and the right box cover and the rectangular hole through grooves of the long hole pressing plates because the two box covers are not required to be directly buckled with each other, the length of the box bottom is not influenced by the length of the box, and the box bottom is only required to be shorter than or equal to the width of the box bottoms of the left box cover and the right box cover.

The plurality of pairs of the grooves and the narrow rectangular through holes mean that the thin rectangular bodies at the bottoms of the grooves deform under stress, so the narrow rectangular through holes are arranged on the outer sides of the thin rectangular bodies, and the grooves and the narrow rectangular through holes are formed in pairs. The number of the pairs of the grooves and the narrow rectangular through holes is properly set according to the width size of the box and the required number of the straight fastening teeth.

The two 90-degree turning arms are bent in a shape that the clamping arm is a section of horizontal part length firstly, turns 90-degree to the center line direction, turns 90-degree forwards after being vertical to a section of size, and extends a section of horizontal size to form a bending shape.

The long groove U-shaped piece is formed by arranging a plurality of pairs of grooves and narrow and long through holes at the U-shaped position of the flat U-shaped piece.

The long hole Y-shaped piece and the long hole pressing plate are rectangular through grooves which are arranged on the double-head Y-shaped piece and the double-inclined pressing plate and correspond to the square vertical teeth of the straight buckling teeth on the long groove U-shaped piece in quantity, position and size.

For the boxes such as the insulation box and the air bag box, if the damping plate, the insulation plate, the air bag and the like are not properly arranged at the bottoms of the front box cover and the rear box cover, the box needs to be properly arranged at the bottoms of the left box cover and the right box cover. At this time, the positions of the inner layer and the outer layer of the front box cover bottom and the rear box cover bottom are exchanged with the positions of the inner layer and the outer layer of the left box cover bottom and the right box cover bottom, namely, the left box cover bottom and the right box cover bottom are positioned on the inner layer, and the front box cover bottom and the rear box cover bottom are positioned on the outer layer. If the length difference between the folded front box cover bottom and the folded rear box cover bottom and the left box cover bottom and the right box cover bottom affects the stacking of the folding boxes, the telescopic devices are additionally arranged in the front box cover bottom and the rear box cover bottom. The box is sealed by stretching, so that the horizontal climbing buckle can be buckled. When folded, the folding chair can be pushed back to the original position.

The concrete method is that a square hole edge sealing piece is used for replacing an edge locking piece to be arranged at the opening part of the box board, and the flat-top corrugated board at the same position with the rectangular through hole is removed. The square hole edge sealing piece is characterized in that a plurality of rectangular through holes communicated with a Y-shaped structure are formed in the front face of a flat plate of the edge sealing piece, and the number of the rectangular through holes is properly set according to the width of the box bottom of the front box cover and the rear box cover. And the T-shaped strip is arranged in the square hole of the square hole edge sealing piece. The left and right of the head of the T-shaped strip are provided with shoulders, and the tail of the T-shaped strip is provided with a riveting hole. The T-shaped head is slidably mounted in the soft box plate. And a notch with the same position and size as the square hole of the square hole edge sealing piece is formed in the Y-shaped position of the non-inclined edge locking piece provided with the horizontal climbing buckle, and the tail part of the T-shaped strip is pressed by two straight pressing plates and riveted. Just so will tie and climb the knot and part with the boxboard, lengthen the lock during the joint sealing, retract during folding, make things convenient for the pile up neatly to pack.

The diameter of two outer semicircles of the double-hole connector is equal to the wall thickness of the box plate, the length of a central connecting line of the two semicircles is equal to the wall thickness of the box plate, and the aperture of the two inner semicircles is equal to the diameter of the rotating shaft. The concave section connected with the two flat U-shaped part convex sections is formed by rotary cutting a circular milling cutter with the diameter equal to the wall thickness along the central lines of the two inner circular holes respectively, a cross section formed by a central connecting line and a cross-over midpoint perpendicular line is provided with two semicircular crescents, each semicircular crescent is divided into two crescents along the central connecting line, and therefore four crescents are formed. Three crescent moon blocks which obstruct the folding are removed to ensure that the excircle of the convex section of the matched U-shaped piece rotates in the groove, and a crescent moon is left to connect the convex sections at the two ends of the remaining concave section. The back of the crescent is added with a reinforcing plate, also called a back plate, with the width less than or equal to the wall thickness 1/2 and with proper thickness. The plate extends vertically through the entire dual-bore coupling to increase the strength of the crescent.

In the double-hole connector, the circular hole with the concave section removed with two crescent is a fixed hole. Because the long vertical U-shaped piece matched with the U-shaped piece rotates relatively within the range of 0-180 degrees. The circular hole of the concave section with a crescent removed is a moving hole, and the wide vertical U-shaped part matched with the circular hole rotates relatively within the range of 0-90 degrees. Crescent moon and backplate are in the case medial surface, and the backplate does not influence the outward appearance of case.

One of the vertical box boards in the reverse folding box is selected and cut along the line of the outer vertical edge of the opening end of the fixed frame, the whole vertical box board is divided into two large and small blocks, the inner side of the opening end of the large block is provided with a plurality of positioning sliding grooves, the back of the large block is provided with the fixed frame of a Y-shaped structure, and the left side and the right side of the vertical female buckle body are provided with circular beads. The mouth parts of the upper and lower side surfaces in the positioning sliding groove are provided with limit tables, and an inner groove-shaped shoulder type slideway is arranged between the bottom surface of the sliding groove and the limit tables by the bottom surface of the fixed frame. Shoulders on two sides of the vertical female buckle body are pressed in the shoulder type slide ways and can slide forwards and backwards. The front slide is in place and is buckled with the vertical male buckle; the back slide is in place, and a vacant position is provided for the vertical male buckle during the reverse folding. Because the reverse folding back, erect box and erect the relative position of public knot unchangeably, but the lock operation is inconvenient, only lets erect the box and retreat and give way. The small block is fixed with a vertical lock edge piece with a positioning clamping groove, and the vertical male buckle is arranged in the positioning clamping groove of the vertical lock edge piece. The vertical lock edge piece is connected with the soft box plate on the small block and the fixed frame is connected with the soft box plate on the large block, and the inner edge part and the outer edge part of the soft box plate are pressed in the grooves at two sides of the Y shape by the straight pressing plate and are riveted by the rivet. The vertical lockrand piece is made integral with the vertical U-shaped piece on the nub if the soft box board on the nub is insufficient to couple the vertical lockrand piece. After the vertical and horizontal climbing buckles are buckled, the complete box is formed.

The upper and lower ends of the fixing frame are connected in the Y-shaped grooves of the upper and lower long transverse U-shaped pieces of the vertical box plate through rivets, and the small inclined plane of the Y-shaped part needs to be removed so as to keep the stable fit of the joint surface of the fixing frame and the Y-shaped groove. The back of the fixed frame is provided with a Y-shaped structure so as to be convenient for connection and fixation with the soft box plate.

After the knot was opened to erect the tie, the perpendicular casing of case just was broken, and the boxboard just can tile and expand, because of the diplopore connector can rotate 180, around vertical axis with length, wide boxboard reverse folding, the inside surface upset of case outside, original surface upset inside, the mode that makes the surface laminate mutually with the surface outside the case is folded, this kind of folding is also called the reverse fold. The inner surface and the outer surface of the box are changed from inside to outside, so that the damping plate, the heat insulation plate, the damping cone plate and the heat insulation cone plate which are originally arranged on the inner surface of the box are turned to the outside at the moment, and the folding of the box is not influenced by the larger thickness of the damping plate; the box bottom of the box cover is respectively folded upwards and downwards around the transverse shaft, the outer surfaces of the box cover and the box bottom are attached, and the inner surface of the box cover and the inner surface of the box bottom face outwards.

The disconnected box plates can be easily connected and opened only by adding a plurality of pairs of vertical and horizontal climbing buckles between the two disconnected box plates. The primary positioning during the buckling of the male buckle and the female buckle in the vertical and horizontal climbing buckle is realized by the mutual matching of the upper surface and the lower surface of the inner side of the opening of the fixing frame and the outer end surface of the sliding chute with the upper surface and the lower surface of the vertical locking edge piece and the three surfaces of the front end surface. Each vertical box button needs to use a sliding groove, and the box plate for mounting the vertical box button is also called a vertical box button plate. The vertical male buckle and the vertical lock edge piece are fixed on the small box plate which is disconnected, the box plate is called a vertical male buckle loose-leaf plate, and the vertical horizontal climbing buckle is buckled or opened in a rotating mode.

The vertical female buckle body and the buckling and pressing plate are penetrated into a whole by the buckling shaft to form a vertical female buckle, the vertical male buckle is the same as the male buckle, and the vertical lock edge piece is the same as the lock edge piece. The vertical male buckle and the vertical locking edge piece are only matched with the vertical female buckle.

The vertical female buckle body is formed by additionally arranging left and right shoulders on the female buckle body and canceling a U-shaped through groove and a riveting hole at the tail part.

The inflating valve is arranged in a fixed round hole of an elbow U-shaped piece, a Y-shaped structure in the U-shaped piece deviates towards the direction of the outer surface, a vacant position which is larger than the thickness of the air bag which can be installed after air exhaust is arranged on the inner side of the U-shaped piece, a pit is formed by simultaneously deviating the Y-shaped structure of the frame, an air bag group is installed at the pit by using a rubber nail, air bags are installed on four vertical box plates and pits on the inner sides of the bottom of the front box cover and the bottom of the rear box cover, all the air bags are communicated by using an air channel, and an air bag box which can inflate the air bags when in use and deflate and fold the air bags when not in use is formed. The air bag is inflated when the case is used, and is deflated and folded when the case is not used.

The elbow U is the key structure that the box can be folded. The wide box plate connected to the U-shaped part of the elbow is folded back to the inner side of the box, and the elbow provides a rotation fulcrum and a folding vacancy for the rotation of the wide box plate. The height of the bend is equal to a wall thickness for the pivotal connection with the wide box plate while leaving a space for its folding.

The distance between two outer side planes of two short vertical plates of the Y shape is equal to the thickness of the flat-top corrugated plate, namely, the two outer side planes are supported inside the inner and outer face plates. The structure is used for smoothly transiting the edge parts of the inner panel and the outer panel into the groove along the inclined plane body and then being pressed and riveted by the pressing plate. The Y-shape in the frame mainly plays a role in connecting the frame with the soft box plate and is a bridge for transition between soft and hard. Therefore, the three problems of compression resistance, shock absorption and light weight can be separately designed, the compression resistance and the load bearing are mainly completed by the frame, and the structural design problem of the U-shaped part is particularly solved. By changing the internal structure of the U-shaped part, the bearing capacity and strength of the U-shaped part can be changed, for example, the thickness and the thin size of the U-shaped flat opening part are increased, and the bearing capacity can be increased by widening, thickening, changing materials with different properties, adding reinforcing rib plates and the like. And shock absorption and light weight are achieved by the soft case plate. Three plates of the soft box plate are generally made of plastics, the toughness and the strength of the soft box plate are much higher than those of paper, and a plurality of different damping effects can be achieved by changing the waveform size or the arrangement density of the middle flat-top corrugated plate, the thickness of the plate and the materials. So that the quantitative and qualitative design can be carried out according to the specific technical requirements of the box. Therefore, a set of perfect technical means is provided for the design, production and use of the box to ensure different load-bearing and shock-absorbing quality requirements of the box.

Shock attenuation awl body board and heat preservation awl body board are regular rectangle's cone board, and unilateral oblique angle is 45, and one section straight surface will be kept with the bottom surface of cone body board to 45 initial points, avoids appearing easy damaged oblique closed angle. The bevel angle is 45 degrees, so that when the two conical plate bodies are spliced into 90 degrees, the edge lines of the upper plane and the lower plane of the two conical plate bodies can be aligned with each other. Six cone plates with the same thickness can be spliced into a complete box body, wherein four cone plates are taken as vertical box plates and are arranged on the inner side surfaces of the long box plate and the wide box plate. In addition, the two blocks are used as the box cover and the box bottom, each block 1/2 along the length dimension needs to be divided into two halves which are respectively arranged on the inner surfaces of the front box cover and the rear box cover and the box bottom, so that the box cover and the box bottom can be opened and closed conveniently. And the damping cone plate and the heat-insulating cone plate are wrapped by a low-temperature-resistant and scratch-resistant sheet. The heat insulation material is prevented from being collided and scratched, and plays a certain protection role. Before the packaging, a plurality of disc-shaped nut pieces are pre-installed at the positions of the shock absorption conical body plate and the heat insulation conical body plate which need to be fixed by screws, and the screws are generally installed on the reinforced support rib plates.

In order to eliminate the gap between the surfaces of the joint of the two insulation cone plates, an elastic sealing strip can be embedded in a groove for installing the sealing strip on the insulation cone plate.

The cross section of the flat-top corrugated board is in an isosceles trapezoid structure with a front surface and a back surface which are continuously arranged, the top of the isosceles trapezoid is a section of plane, so that the contact area between the flat-top corrugated board and the inner and outer panels can be increased, and the bonding strength of the soft box board can be improved. The right and reverse tops of the isosceles trapezoid are bonded to form a structure similar to an isosceles triangle, so that the soft box board is good in structural stability and strong in pressure resistance, and can be quickly restored to the original shape even after being deformed under pressure.

By a positive and a negative, it is meant that the short top edge of the isosceles trapezoid is positive at the top and negative at the bottom.

The middle part of the small square through hole at the upper part of the cross shape is provided with a fastening shaft through hole which is vertical to the left and the right and is a place for installing a concentric cylinder at the tail part of the fastening and pressing plate. The length of the cross-shaped middle sliding chute is equal to the sum of the left and right sliding distances of the two lower hooks in the chute, and the width of the sliding chute ensures that the two lower hooks can smoothly enter and exit the sliding chute. The width of the sliding groove is larger than the thickness of the buckle head.

The opening part is the position between the left box cover bottom and the right box cover bottom and the front box cover bottom and the rear box cover bottom and is a place where the box cover bottom can be opened and closed.

The seal is an operation that the box cover and the box bottom cannot be opened by the self force after being closed, and the seal is buckled by a male buckle and a female buckle.

The transverse plate, the flat plate, the vertical plate, the small flat plate, the long vertical plate, the short vertical plate and the plate in the back plate are cuboid components with one thickness, one length and one width and six flat surfaces.

The box is also called a reverse-folded box after being reverse-folded. This is to be distinguished from the folding of a box in which the vertical box panel is not cut through. Because the damping plate and the heat-insulating cone plate can be wrapped, materials which are more environment-friendly, more damping and better in heat-insulating effect than foamed polyester can be used as raw materials of the damping plate and the heat-insulating cone plate.

The shock absorbing plate is an inner lining plate made of a material capable of absorbing the shock and impact of the articles contained in the box.

The heat insulation board is an inner lining board made of a material with certain heat insulation capacity.

The shapes of the damping plate and the heat insulation plate have no special requirements, and the damping plate and the heat insulation plate can be installed in the box only by meeting the use requirements.

The oblique angle refers to an included angle between the oblique plane and the vertical plane.

The pressing plates are the general names of straight pressing plates, double-inclined pressing plates, long-hole pressing plates and 90-degree pressing plates.

The nail and the second are paired with U-shaped pieces, each piece is provided with a convex section and a concave section, the convex section of the first is embedded into the concave section of the second, the concave section of the first is embedded into the convex section of the second, the sizes of the concave and convex sections at the mutual embedding positions are equal, the nail and the second are called to be equidistant, and the concave and convex sections are circularly and alternately embedded, so the nail and the second are called to be concave-convex alternated. After the first and second parts are matched with each other, the circular holes of the first and second parts are kept concentric, the first and second parts rotate relatively within the range of 0-90 degrees after the shaft is penetrated, the bottom of the concave section only can keep a crescent on one side, and the other side has no crescent. The crescent is located the bottom of concave section, can restrict the rotation of convex section to crescent one side, improves concave, convex section complex leakproofness. The key point is that the crescent structure avoids the straight gap between the inside and the outside at the interconnection joint of the long and the wide vertical box plates. The crescent of the concave sections A and B are on the same side surface after being matched with each other, otherwise, the crescent cannot rotate.

The equal distance means that the size of the concave and convex sections embedded into each other is equal, and the size of the concave and convex sections on the matched U-shaped member is not required to be equal, and can be equal or unequal.

The equidistant concave-convex alternate structure is the same as the equidistant concave-convex alternate structure replacing a crescent except that the crescent is not arranged. Because the double-hole connecting piece in the double-hole elbow U-shaped piece rotates 180 degrees around the vertical shaft, the concave section in the connection of the double-hole connecting piece and the long vertical U-shaped piece of the long box plate can not influence the rotating crescent moon, and an equidistant concave-convex alternate structure is adopted. The U-shaped piece connection between the box cover bottom and the long and wide box plates is the same as the double-hole elbow U-shaped piece. The movable hole of the double-hole connecting piece is connected with the wide vertical U-shaped piece of the wide box plate by adopting an equidistant concave-convex alternate structure replacing a crescent.

The air bag is divided into an elastically expandable air bag and an inelastically expandable air bag according to the protection level of the articles in the box, the shape of the elastically expandable air bag can be changed along with the shape of the articles to be protected, the articles can be tightly wrapped by the elastically expandable air bag, if vibration impact is generated, the vibration impact can be automatically absorbed by the elastic deformation of the air bag, and therefore the articles are prevented from being damaged due to the impact. The elastically expandable air bag tightly wraps the article during operation, and no gap exists between the air bag and the article. When the article is impacted by vibration, the article can generate elastic deformation to automatically absorb the vibration impact wave, so the elastic inflatable air bag provides active protection for the article and can protect the article at a high level. Relatively speaking, the inelastically expandable air bag mainly absorbs the shock impact by compressed gas because the air bag has very small elasticity, when the article is impacted by the shock, the article needs to generate certain displacement because of gaps between the article and the air bag, so that the air bag can be pressed to absorb the shock impact, therefore, the inelastically expandable air bag provides passive protection for the article, and the protection level for the article is relatively low.

The air bags have different functions, the materials used for manufacturing the air bags are different, the elastically expandable air bag is made of a film material with certain elasticity, and the inelastically expandable air bag is made of a common film material or a film material with small elasticity. The elastically expandable air bag means that the shape of the air bag can be changed along with the size of inflation pressure, the air bag with large air pressure is also large, and the air bag with small air pressure is also small. The non-elastic inflatable air bag has less capacity of changing the shape along with the air pressure.

The air bag is made of two elastic materials with air inlet expansion or soft materials with air inlet expansion, the air bag and the air passage are designed, and then the air bag and the air passage are buckled into a whole and formed along the periphery of the air bag and the air passage by hot pressing or gluing. Cutting off the redundant part. The air bags are communicated with each other by an air passage, and the air passage is formed by reserving the width of one air passage between the two air bags and is not bonded. The air bags on one box plate can be arranged in one group or a plurality of groups according to the size of the box, and the number of the air bags in each group is set according to the requirement of protection required by the contained goods. The elastically expandable air bags can deform along with articles, and the number of the air bags required by each group is small, or one air bag can be used. The air bags of one box are assembled into an air bag assembly and matched with an air valve which is arranged in a round hole of an elbow U-shaped piece on a long box plate, so that the normal use of the box is not influenced, the operation of inflation and deflation is convenient, and the air valve can be protected from being damaged.

In addition, because the material cost of the elastic inflatable air bag is high, and only one side of the air bag is required to be contacted with an article, the air bag can be bonded by a common non-elastic sheet and an elastic sheet to form the single-side inflatable air bag, so that the cost is reduced. The elastic inflatable air bag can adjust the elasticity of the air bag material according to the shockproof strength requirement of the article so as to adapt to different article protection requirements.

To the case that need not adopt gasbag absorbing, but the shock attenuation board that can select for use absorbing material to make replaces, if the pit of boxboard can not descend the shock attenuation board, can adopt the structure of anti-folding case to six shock attenuation boards can the amalgamation be a case for the standard.

The straight pressing plate and the 90-degree pressing plate are plate-shaped connecting pieces with inclined surfaces and riveting holes formed in one side edge of the flat plate. The double-inclined pressing plate is a double-side inclined plane. The slope of the inclined surface is the same as that of the "Y" shape. The double-end Y-shaped part, namely the two ends of the flat plate are the upper half parts of the Y shape, and is formed by splicing the tails of the lower ends of the two Y shapes with the tails oppositely.

The horizontal climbing buckle is a combination of a male buckle and a female buckle, and the male buckle and the female buckle are buckled and locked during working. Wherein the female button is formed by connecting a female button body and a button pressing plate into a whole by a button shaft.

The male buckle body is a structure from the clamping arm root to the tail part of the male buckle. Comprises two narrow and long vertical through grooves, two small inclined plane platforms, small notches, a U-shaped through groove and a riveting hole. The two ends of the riveting hole are provided with large-angle taper holes which are similar to inner chamfers at the two ends of the round hole, or the taper holes are replaced by large step holes and are determined according to the shape of the used rivet.

The positioning buckle teeth with the shapes of the concave parts and the convex parts which are complementary on the bevel edges refer to that on the 45-degree bevel edges of two Y-shaped parts which need to be matched, at the same position, the concave parts correspond to the convex parts with the same shape, and the convex parts correspond to the concave parts with the same shape. Complementation is the meaning that the concave and convex shapes on the two mating bevel edges can be mutually jogged.

The positioning buckle teeth not only play a role in positioning and connection, but also can bear shearing force generated on the bevel edge, so that the frame is kept stable.

The Y-shaped part refers to a component with a Y shape for forming the box board frame, namely a U-shaped part, an edge sealing part, an elongated slot U-shaped part, a square hole edge sealing part and an edge locking part. A fixed frame with a "Y" shape is not included here.

The air bag is made of different materials, and can be divided into an elastic expansion air bag and a non-elastic expansion air bag.

The horizontal climbing buckle has the working sequence that when the buckle is hung in the first step and the male buckle and the female buckle are buckled, the buckle head firstly enters the upper buckle platform, the lower buckle platform and the chute of the female buckle, and at the moment, the male buckle and the female buckle are in a hooked state, but are easy to unhook due to accidents. And secondly, locking, namely pressing the buckling and pressing plate to push the spring bolt into the lock hole until the buckling and pressing plate is buckled. Therefore, no matter how the male buckle and the female buckle bump, the oscillating force can be absorbed by the combination of the lock tongue and the lock hole without influencing the buckling of the horizontal climbing buckle. If there is no lock tongue, lock hole and pressure platform, the smooth buckle clamp plate presses the buckle head, and the buckle clamp plate is likely to produce the anti-prying effect to the jaw of the pin buckle because of the external force bumping effect, so that the possibility of tripping the buckle clamp plate is provided, thereby leading to the flat-climbing buckle failure and the case to be damaged. Because of the case is often in unpredictable adverse circumstances, in order to guarantee that the level climbs the knot and stabilizes the closure all the time, had increased the structural design of a spring bolt, lockhole, pressure platform.

The pressing and buckling, the unbuckling and the yielding are carried out, wherein the pressing and buckling means that the buckling plate is pulled downwards from the yielding state to push the spring bolt to enter the lock hole until the buckling teeth of the buckling plate are buckled; the buckle teeth are pried from the small notch when the buckle is released, the buckling plate is pulled upwards, and the lock tongue exits from the lock hole under the action of the resilience force of the clamping arm; the abdicating is that the front surface of the buckling plate leans against the abdicating inclined plane, thereby facilitating the operations of male and female hasp and tripping and not hindering the opening and closing of the box cover.

When the box is opened, the buckling teeth of the U-shaped buckle on the buckling plate are pried by a tool, the buckling plate is pulled upwards, so that the double inclined planes of the buckling plate are separated from the inclined plane of the buckling head, the spring bolt automatically withdraws from the locking opening under the action of the resilience force of the clamping arm, and the locking state is released.

The seemingly repeated design of the upper buckling table, the lower buckling table, the lock hole and the pressing table aims to fully utilize the limited space of the wall thickness of the box and provide an effective structure as much as possible. Due to the wall thickness, a single structure may result in insufficient strength. The thickness of the flat fastener is not limited by the wall thickness, but is generally equal to the wall thickness for covering and folding.

The buckling force of the horizontal climbing buckle mainly comes from the mutual hooking of the upper buckling platform, the lower buckling platform, the upper buckling hook and the lower buckling hook, and the cooperation of the lock tongue, the lock hole, the pressing platform and the clamping arm mainly limits the vibration or bounce generated by the buckling head and the clamping arm under the action of uncertain external force so as to influence the stability of the buckling plate and ensure that the horizontal climbing buckle can maintain normal locking in any severe environment.

The box is mainly made of engineering plastics, and some boxes with special requirements do not exclude the use of metal materials or the use of metal materials for manufacturing parts. In particular, the box board structure described in patent number ZL2020205183175 is most suitable for use as a soft box board.

The invention has the following beneficial effects:

the frame of the box plate can be made of high-strength and high-toughness materials, and the box plate can be used as a main framework of the box, can bear larger weight and larger impact force, and is very suitable for large-scale accumulation and rapid transportation. The load bearing of the soft box plate is not a main problem, the soft box plate can be made of thin sheets, and the soft box plate is shock-resistant, light in weight, good in toughness and not afraid of moisture. Therefore, the three problems of load bearing, shock absorption and light weight are considered separately, and the load bearing can be used for quantitatively and qualitatively designing a frame structure according to the requirements of products. The performance of the used engineering plastic is stable, and the product can easily meet the design requirement and is slightly influenced by the environment. Not much like cardboard uncontrollable factors. The rivet and the pressing plate are connected firmly and reliably. When the folding and unfolding are carried out, the box plates rotate around the shaft, so that the folding and unfolding are easy and convenient, and the edges and corners are not easy to damage. The flat-climbing buckling sealing box is convenient, quick, safe and reliable. Avoiding a packing belt and a sealing adhesive tape. The structure and the material of the box ensure that the box is not easy to damage and lose efficacy, thereby being capable of being recycled. And the folding type portable trolley is convenient for empty box storage and large-scale long-distance transportation. In particular, the use amount of the white foamed polyester can be reduced in the heat preservation box and the air bag box.

The box board of the box is spliced, so that spare parts can be produced in large quantity by injection molding, extrusion molding and other methods, and boxes with various sizes can be produced only by cutting and splicing.

Detailed Description

Example 1:

in order to save space and facilitate use, storage and transportation, the design mode of full connection, full folding and no detachable parts is adopted during folding.

This example mainly describes the box and the main structure of each part, which is composed of soft box board, U-shaped piece, shaft and flat climbing buckle.

Fig. 1 is a schematic isometric view of the box of this embodiment after being sealed, and a left box board 13, a right box board 4, a front box board 12 and a rear box board 1 constitute a main body structure of the box, which is long, wide and high. The axis 11 represents the horizontal axis, vertical axis, and rotational axis. The left box cover 2 and the right box cover 3 are arranged on the topmost layer of the box, and the front box cover 5 and the rear box cover 6 are arranged below the topmost layer. The left box bottom 10 and the right box bottom 7 are arranged on the bottommost layer of the box, and the front box bottom 8 and the rear box bottom 9 are arranged on the bottom layer. The width of the bottom of the left box cover and the right box cover is equal to the dimension of 1/2 locking edge pieces of the width of the boxes exceeding the center line part of the width of the boxes, and the length of the locking edge pieces is equal to the length of the boxes. The length of the bottom of the front cover and the rear cover is equal to 1/2 of the length of the box, the locking edge piece exceeds the size of the central line part of the length of the box, and the width is equal to the width of the box, and two wall thicknesses are subtracted. The problem that the size of the part of the lockrand exceeds the central line is solved because the opening of the box bottom of the box cover is sealed by adopting the horizontal climbing buckle, and the lockrand parts at two sides of the box opening are mutually covered.

Because the case of the present embodiment does not adopt a packing belt and a case sealing adhesive tape, for the case needing to prevent the case from being exposed to the outside at the wide case plate, the horizontal climbing buckles are also arranged at the bottoms of the front case cover and the rear case cover, so that the wide case plate can not be exposed to the outside and exposed to the outside under the locking force of the horizontal climbing buckles.

The box bottoms of the front box cover and the rear box cover are not only ensured that the wide box plate does not leak laterally, but also ensured that the unfolded rear box is square and stable, the width of the box bottoms of the front box cover and the rear box cover is equal to the clearance width of the inner side of the box, the box bottoms of the left box cover and the right box cover are also positioned on the inner side surfaces of the box bottoms of the left box cover and the right box cover, the inner side surfaces of the upper end and the lower end of the left box plate and the right box plate can be supported and supported, the box plates cannot deviate to the inner side, and the trend of the box plates to deviate to the outer side is controlled by the horizontal climbing buckle of the box bottoms of the left box cover and the right box cover in a tensioning mode. Thus, although the four corners of the box are connected by the rotating shafts, the squareness of the box after being unfolded cannot be ensured. But the support of the two sides of the width of the box bottom of the front box cover and the rear box cover and the tightening of the horizontal climbing buckles in the box bottom of the left box cover and the right box cover ensure the squareness and the stability of the box.

Fig. 2 is a schematic view of the folded isometric structure of the product of this embodiment, the folding method is the same as that of the common carton, all the horizontal climbing buckles are unfastened, the left box cover 2, the right box cover 3, the front box cover 5 and the rear box cover 6 are folded by being turned upwards by 90 degrees, and the left box bottom 10, the right box bottom 7, the front box bottom 8 and the rear box bottom 9 are folded by being turned downwards by 90 degrees. Then the long box plate and the wide box plate are pushed to move towards the inner side of the box until the inner side surfaces of the box are completely attached. The front box board 12 and the left box board 13 are mutually stretched and flattened, and the rear box board 1 and the right box board 4 are mutually stretched and flattened. The front box board 12 is positioned on the inner side surface of the elbow U-shaped part 21 of the right box board 4, the rear box board 1 is positioned on the inner side surface of the elbow U-shaped part 21 of the left box board 13, and all parts of the box are folded into a whole, so that the storage and the transportation are convenient.

Figure 3 is a schematic isometric view of the right box panel 4 most prominently featuring the configuration of the elbow U-shaped member 21, which is critical to the successful folding of the box. Fig. 12 is a cross-sectional view of the elbow U-shaped member 21, which is formed by solidifying the double-hole connector 33 and the vertical U-shaped member 43 at mutually perpendicular positions and removing the back plate, and the fixed hole is formed by changing the fixed circular hole into a square hole for uniform wall thickness without passing through a shaft, and the original circular hole is kept unchanged. The distance between the center of the U-shaped round hole and the inner side surface of the box is equal to 1/2 of the wall thickness dimension of the box. I.e. the distance from the top of the outer circle of the U-shaped part to the inner side is equal to the wall thickness of the box. So as to ensure that the front box board 12 matched with the front box board can be rotated by 90 degrees towards the inner side and is parallel to and jointed with the right box board 4, namely, the front box board is folded at the inner side of the elbow U-shaped part 21.

Fig. 5 is a schematic diagram of the frame isometric structure of the right box plate 4, and the right box plate 4 is manufactured in three steps: first, a rectangular frame is made, and the length and height of the right box plate 4 are higher than the length and height of the box. Each U-shaped part is prefabricated with a 45-degree bevel edge at two ends of the length and a positioning buckle tooth on the bevel edge according to design, and the positioning buckle tooth is of a convex-concave structure on the bevel edge. As shown in fig. 6 and 7, the positioning buckle teeth are distributed on the 45-degree oblique edges at the Y-shaped positions of the two ends. A right rectangular frame structure with transverse U-shaped parts and vertical U-shaped parts perpendicular to each other is formed by dividing one elbow U-shaped part 21 and one long vertical U-shaped part 15 into two sides in the length direction and dividing two long transverse U-shaped parts 20 into the upper end and the lower end in the height direction. The positioning buckle teeth at the four corner joints are mutually embedded, so that the frame is accurately positioned and primary connection is realized. The inside edge of the 90 deg. press plate 14 has a bevel dedicated to joining two Y-shaped members at 45 deg. bevel edge seams, one inside and one outside each seam, used in pairs. A frame with four corners requires a total of eight 90 deg. press plates 14. Secondly, installing a soft box plate 17, and prefabricating holes for penetrating rivets on the peripheral edge of the soft box plate 17. Thirdly, the peripheral edges of the inner panel and the outer panel of the soft box board 17 are pressed in the grooves at two sides of the Y shape by a 90-degree pressing board 14 and a straight pressing board 16, and the two sides are riveted and fixed by rivets 19 after being pressed.

As shown in figure 3, if the frame strength is insufficient, a double-inclined pressing plate 18 and a double-head Y-shaped part 59 can be additionally arranged, wherein the double-inclined pressing plate 18 is arranged on two sides, one inside and one outside, and is tightly pressed and fixed by a rivet 19. As shown in fig. 16, double-ended Y-shaped member 59 is located in the middle and the double-ended Y-shaped structure supports inner panel 31 and outer panel 29 of the hose board 17. The double inclined pressing plates 18 are pressed on the inner and outer surfaces of the soft box plate 17 and fixed by rivets 19.

For a frame with a larger height, a double-headed Y-shaped member 59 and a double inclined pressing plate 18 may be added in the horizontal direction. The number of the added-up is determined according to actual requirements. The double ramp plate 18 and double Y-piece 59 can be eliminated if the frame strength is sufficient to meet the box specifications.

Fig. 15 is a partial cross-sectional view of the long cross U-shaped member 20 and the soft box board 17 of the right box board 4, which more clearly shows the long cross U-shaped member 20, the straight pressing plate 16, the rivet 19, and the inner panel 31, the outer panel 29 and the top corrugated board 30 of the soft box board 17 in partial structures and assembled relation to each other. The first is a long transverse U-shaped element 20, which is made up of two parts, one of which is a U-shaped hole portion, where, in view of the shrinkage of the plastic material, two rectangular slots are made between the inner hole and the flat mouth portion, so that the wall thickness is as uniform as possible. The other is the Y-shaped double-sided slot part, i.e. the thin vertical plate with rivet holes is vertically drawn at the lower half of the Y and is positioned in the middle of the U-shaped soft box plate 17. The double inclined plane body of the upper part of the Y-shaped part and the two outer side planes of the two short vertical plates play the roles of supporting and transition. The distance between the inner side surfaces of the inner panel 31 and the outer panel 29 for supporting the soft box board 17 is equal to the height of the flat-top corrugated board 30. The inclined surface is used for ensuring that the edge parts of the inner and outer panels of the soft box plate 17 are transited to the thin vertical plate in the groove along the inclined surface. The straight pressing plates 16 are used in pairs, one inside and one outside are provided, and one side of the soft box plate 17 is provided with an inclined plane with the same angle as the Y-shaped double inclined planes. Similarly, the surface of the 90 ° press plate 14 that contacts the soft box plate 17 is also beveled.

The soft box board 17 is composed of an outer panel 29, a flat-top corrugated board 30 and an inner panel 31 which are bonded together. Is generally made of plastics and has the characteristics of light weight, strong shock resistance, high toughness and moisture resistance. The flat-topped corrugated sheet 30 is formed by a forward and a backward continuously arranged isosceles trapezoid, the top of the isosceles trapezoid is a section of plane, which can increase the contact area with the inner and outer panels, thereby improving the bonding strength.

FIG. 11 is a cross-sectional schematic view of a flat U-shaped member, wherein a concentric inner circular hole is added to the arc portion of the U-shape with the opening sealed, and the inner hole is a complete circular hole without considering deformation and uniform wall thickness, and one end of the sealed part is called a flat opening part. The Y shape is that the top of the vertical plate is provided with inclined planes symmetrically extending to the left and right sides, and the top of each inclined plane is provided with a short vertical plate parallel to the vertical plate. The lowest end of the Y shape is vertical to the flat mouth part of the U shape.

The Y-shaped configuration in the elbow U-shaped member 21, the long upright U-shaped member 15, the closeout member 22, the lockdown member 23, and the long lid U-shaped member 25 is substantially the same size and long cross U-shaped member 20.

The front box board 12 and the rear box board 1 are structured in such a way that two wide vertical U-shaped pieces are symmetrically arranged at two sides of the box in the width direction, and two wide transverse U-shaped pieces are symmetrically arranged at the upper end and the lower end of the box in the height direction. The rest of the structure is identical to that of the right box plate 4. The width dimension of the wide box panel is reduced by the total width of the box by a wall thickness dimension, since one end of the wide box panel is strung together with the bent U-shaped part 21 of the left and

right box panels

13, 4, the bent U-shaped part 21 taking up a wall thickness. The box bottoms of the front box cover and the rear box cover which are connected with the front box plate and the rear box plate are respectively positioned on the inner side surfaces of the box bottoms of the left box cover and the right box cover, and the height of the wide box plate is equal to the total height of the box, except for two wall thicknesses.

Fig. 4 is a schematic isometric view of the right case cover 3, and the edge sealing members 22 are two, and are symmetrically disposed at two ends of the right case cover 3 in the length direction. The locking edge pieces 23 and the long cover U-shaped piece 25 are arranged in a same piece and are oppositely distributed at two ends of the width direction of the right box cover 3 to form a regular rectangular frame. According to the assembling relation of the box, the right box cover 3 and the right box plate 4 are matched at the position of the transverse shaft, the long transverse U-shaped part 20 and the long cover U-shaped part 25 adopt an equidistant concave-convex alternate structure to be matched with each other, the circular holes of the two U-shaped parts are matched with each other to be concentric circular holes, and the two U-shaped parts can be connected into a whole by the shaft 11 in series. The crescent of the concave section is cancelled, so that the opening angle of the box cover is larger than 180 degrees, and articles can be conveniently taken and placed. The soft box plate 17 is installed in the same manner as the fixing method and the right box plate 4.

As shown in fig. 6, two positioning slots for installing the male buckle 24 are provided on the locking edge piece 23, the width dimension of the positioning slots is the same as that of the male buckle 24, and the rivet hole on the Y-shaped slot is matched with the rivet hole at the tail of the male buckle 24. The tail U-shaped groove of the pin 24 is fixed to the Y-shaped plate of the lockrand 23 with a rivet 19. The structure size of the locking edge piece 23 adjacent to the male buckle 24 is equal to or larger than the corresponding size of the male buckle 24, so as to play a role in protecting against collision and scratching.

As shown in fig. 1, the left cover 2 has substantially the same structure as the right cover 3 except that a female button is provided on the locking edge of the left cover 2. The left box bottom 10 and the right box bottom 7 are arranged at the lower end cross shaft of the left box plate and the right box plate, and the structure and the arrangement of the left box bottom and the right box bottom are the same as those of the left box cover and the right box cover. The structures of the front box cover 5, the rear box cover 6, the front box bottom 8 and the rear box bottom 9 are basically the same as those of the left box cover bottom and the right box cover bottom.

Fig. 6 is an isometric view of the lockside member 23 of the right cover 3, and fig. 14 is a cross-sectional view of the lockside member 23. The main structure is Y-shaped and perpendicular to a plate member, one end of the plate member is provided with a long vertical plate member extending downwards, and the lower end and the near middle part of the long vertical plate member are provided with two small plates in the same direction as the plate member. The long vertical plate is prevented from deforming due to the thinness of the plate, and the long vertical plate plays a role of reinforcing ribs. After the box is sealed, the box plays a role in mutual supporting and isolating dust and sundries. The Y-shaped 45-degree bevel edge at the two ends of the lockrand 23 is provided with a concave-convex positioning buckle tooth. Two notches on the long vertical plate are two positioning clamping grooves which are used for installing the male buckle 24, and the riveting holes on the Y-shaped thin plate at the bottom of the clamping grooves are used for fixing the male buckle.

Fig. 7 is an isometric view of the edge banding 22 of the right cover 3, and fig. 13 is a cross-sectional view of the edge banding 22. The cross-sectional configuration is Y-shaped perpendicular to a plate member. The bevel edge of the sealing piece 22 with two ends of Y-shaped 45 degrees is provided with a concave-convex positioning buckle tooth. The shape, position and size of the positioning buckle teeth are the same as those of the positioning buckle teeth of the lock edge piece 23 at the matched position, but the concave and convex positions are exchanged, namely the concave and convex shapes on the two pieces are complementary. The small round holes arranged along the Y-shaped groove are rivet holes for fixing the rivets of the soft box plate and the pressure plate.

Fig. 28 is a front view schematically showing the structure of the flat buckle, which is opened, and the buckling plate 27 is leaned against the yielding slope. Fig. 29 is a schematic top view and fig. 30 is a schematic isometric view of a flat fastener, which is composed of four parts, namely a male fastener 24, a female fastener body 26, a fastening plate 27 and a fastening shaft 28. The female buckle body 26 and the buckling plate 27 are connected in series by the buckling shaft 28 to form a female buckle. The male buckle 24 and the female buckle are called a horizontal climbing buckle and are key parts of the box, the structure is slightly complex, and the box is simple to operate, convenient and fast to use, firm and reliable. And will be described in more detail below.

The hole end of the buckling plate 27 is arranged in a square through hole in the middle of the female buckle body 26 and is penetrated into a whole by the buckling shaft 28, and the buckling plate 27 can swing around the buckling shaft 28 within a certain angle range so as to realize actions of buckling, unbuckling and abdicating.

Fig. 22 is a front view of the female buckle body 26, and fig. 24 is an isometric view of the female buckle body 26, the female buckle body 26 being symmetrically arranged along a center line between left and right sides. The front platform is extended from the bottom and is provided with a abdication notch, and the front platform is mainly used for providing a support plane for a pair of clamping arms of the male buckle 24. The abdication gap of the front platform is of a concave shape and is designed for partial abdication of the bottom surface of the U-shaped buckle of the buckle pressing plate 27, and the length size of the front platform ensures the proper distance between the male buckle and the female buckle. The middle part has more structures and mainly surrounds the periphery of the through hole with the central part similar to a cross shape. The top of the cross shape is provided with a relief slope H, when the flat climbing buckle is unfastened, the front surface of the buckling and pressing plate 27 can lean on the relief slope H so as not to obstruct the normal opening or buckling of the jaws of the male buckle 24. The middle of the cross-shaped small square-mouth through hole at the upper part is provided with a round through hole which is vertical to the left and the right and has the same diameter with the through hole at the tail part of the buckling plate 27 and the buckling shaft 28. The long through groove in the cross-shaped middle part is a sliding groove, and the two lower hooks C of the two hooks on the clamping arm can slide left and right in the sliding groove. The length of the sliding groove, namely the distance between the two sliding stop surfaces N of the sliding groove, is not less than the distance between the sliding stop platforms Z of the two lower clasps C after buckling. The long vertical surface of the sliding groove near the front end is a lower buckle platform J, and is attached to a lower buckle C of the male buckle 24 during buckling. The surface of the lower buckling platform J is extended up along with two symmetrical rectangular platform columns which are the upper buckling platform G, and the left side and the right side of the upper buckling platform G are respectively provided with one rectangular platform column. The maximum distance that the two clamping arms can swing is reserved between the left upper buckling platform G and the right upper buckling platform G, namely the maximum distance cannot be smaller than the size of the contact position of the outer side surfaces of the two clamping arms and the left upper buckling platform G and the right upper buckling platform G after buckling. The two pressing platforms S are symmetrical left and right and are positioned at the upper parts of the left and right upper buckling platforms G towards the center. Two through holes which take the locking surface M as an initial surface are arranged on the platform surfaces at the left side and the right side of the sliding groove, namely locking holes I, wherein the left side and the right side are respectively provided with one locking surface M, and the hole walls of the locking holes I are closed. The right upper buckle platform G extends rightwards to the right side surface of the female buckle body 26 to form a section of hole wall of the right lock hole I; the upper left buckle G extends leftwards to the left side face of the female buckle body 26 to form a section of hole wall of the left lock hole I. The plane between the locking surface M and the sliding surface N is the extension of the bottom planes of the left and right lock holes I, and the large step surface P of the lock tongue B can slide back and forth on the plane. The surface of the lower buckling platform J connected with the left upper buckling platform G and the right upper buckling platform G is the buckling surface of the female buckling body. A short through groove is formed in the middle of the lower buckling platform J, namely the lower half part of the cross shape, and is used for yielding the double-inclined-surface boss of the buckling pressure plate 27 during swinging. The middle of the tail part of the female buckle body 26 is provided with a U-shaped through groove, the structural shapes of the upper groove body and the lower groove body are similar to that of the straight pressing plate 16, and round holes with chamfers are arranged on the upper surface and the lower surface of the groove body for mounting rivets.

Fig. 23 is a schematic front view of the male buckle 24, and it can be seen from the figure that the clip arm is a bent clip arm formed by a horizontal part of length, turning 90 ° toward the center, turning 90 ° forward after a vertical part of size, and extending a horizontal size, that is, two 90 ° clockwise turns. The inner and outer right angles at the corner are in smooth transition by using circular arcs.

Fig. 25 is a schematic isometric view of the male buckle 24, which is symmetrically disposed along a center line between the left and right sides, and is divided into front, middle and rear portions. The front end is two buckles with the same shape and symmetrically distributed, two lock tongues B on the buckles face to the left and the right respectively, the shape of the two buckles is the same as that of the lock hole I, and the two lock tongues B can enter the lock hole I and can slide easily. The step between spring bolt B and the button head top surface is locking platform W, and it is for the length that control spring bolt B got into lockhole I, and when locking platform W and locking surface M laminated, spring bolt B just stopped moving. The left and right opposite inclined planes of the two button heads are pushed inclined planes A which are matched with a main pushing inclined plane K on the button plate 27, and the inclined angle between the inclined planes and the vertical line perpendicular to the bottom surface is smaller than 12 degrees, so that larger thrust can be ensured and self-locking can be realized, namely, the button plate 27 cannot be bounced by the button head due to the reverse thrust generated by the elasticity of the clamping arm. The bottom edge line of the pushed inclined plane A is intersected with the bottom surface of the lower clasp C, the bottom surface of the lock tongue B is a large step surface P, a step is arranged between the large step surface P and the bottom surface of the lower clasp C and is called as a sliding stop platform Z, and the height of the sliding stop platform Z is equal to the depth of the chute of the female clasp body 26. The large step surface P can slide on the bottom plane of the lock hole I of the female buckle body 26. The top surface of the button head is flush with the front surface of the male button 24. The distance between the outermost left and right surfaces of the lock tongue B and the locking surface M of the female buckle body 26 should be greater than zero when the male buckle 24 is not buckled, so as to ensure that the jaws of the male buckle 24 can be buckled and unbuckled smoothly. The upper clasp E is the part of the clasp head extending leftwards and rightwards on the outer sides of the left and right clamping arms and also comprises a lock tongue B. The surface of the buckle head connected with the clamping arm is the hooking surface of the male buckle 24. The hooking surface of the male buckle is mutually attached to the buckling surface of the female buckle body during buckling. The left and right arms in the middle of the male buckle 24 may be straight or curved, depending on the particular configuration. This example is curved. The bend is to give enough space for the U-shaped buckle of the holding-down plate 27 to be long and wide. The inner sides of the root parts of the two clamping arms are respectively provided with a narrow and long vertical through groove which is communicated with the upper surface and the lower surface of the male buckle 24. The length of the root of the clamping arm is increased to reduce the swing angle of the clamping arm when the buckle moves, so that the plastic deformation possibly caused by the overlarge swing angle due to the overlarge swing angle caused by the overlarge length of the clamping arm is avoided. The central line of the small notch D is coincident with the central line of the male buckle 24, and small inclined plane platforms F are distributed on the two sides and are used for reducing the resistance when the buckle teeth L are buckled. The lower table-board of the small inclined plane platform F is attached to the front surface of the buckle tooth L after buckling. When the horizontal climbing buckle needs to be opened, a small horizontal screwdriver is inserted into the small notch D, the buckle teeth L are pried to be separated from the small inclined plane platform F, then the buckle pressing plate 27 is pulled, and the two buckle heads gradually exit from the lock hole I under the action of the resilience force of the clamping arms along with the gradual separation between the main push inclined plane and the pushed inclined plane, so that the horizontal climbing buckle can be unfastened. The tail structure of the male buckle 24 is the same as the tail structure of the female buckle body 26.

Fig. 26 is a front view structural diagram of the pressing plate 27, and the isometric structural diagram of the pressing plate 27 in fig. 27 is distributed symmetrically along the center line between the left and right sides, and is divided into three sections, namely a front section, a middle section and a rear section, a U-shaped buckle with a buckle tooth L is arranged in a long notch at the front end, the U-shaped buckle is composed of a fixed hook and a movable hook, the fixed hook is connected with the back of the pressing plate 27 panel into a whole, and the buckle tooth L is arranged on the outer side of the movable hook. The cross section of the button tooth L is similar to a right triangle, and a V-shaped through groove is formed in the position, close to the inner side, of the straight top edge. The space between the left end and the right end of the U-shaped hook and the long notch is used for enabling the U-shaped buckle to be independent so as to facilitate the swing of the movable hook under the action of external force. The slightly convex vertical platform in the middle gap of the buckle tooth L is a small middle gap matched with the male buckle body, so that the buckle tooth L can be conveniently pried by a tool. The pressing plate is also the body of the buckling and pressing plate 27 and is responsible for connecting the front section, the middle section and the tail section into a whole. The area of the panel is larger in order to shield the clamping arm of the male buckle after buckling. The middle part is mainly a double-inclined-plane boss consisting of two symmetrical main push inclined planes K. The tail part is mainly of a concentric circular ring structure. The circular hole of the shaft can be threaded through the shaft 28.

Fig. 20 is a schematic view of the two U-shaped members at 90 ° after mating with each other, and fig. 21 is a schematic view of the two U-shaped members at 0 ° after mating with each other. The crescent on one side of the concave section of the U-shaped part is integrated with the bottom of the concave section, and can limit the rotation of the matched convex section to one side of the concave section, namely limit the rotation of the matched U-shaped part to one side of the concave section. The relative rotation of the U-shaped pieces in the range of 0-90 degrees is allowed, and because of the folding and unfolding of the box, the relative rotation of the adjacent long and wide box plates only needs to be 0-90 degrees. The crescent is the detail structure of the U-shaped part, and the structure of the crescent is not shown in the assembly drawings of the rest of the drawings for the convenience of drawing. The crescent has the functions of limiting the unilateral rotation of the U-shaped piece and avoiding the inner and outer bilateral swing of two long and wide box plates at the joint; and secondly, straight inner and outer gaps at the bottom of the groove of the matched U-shaped part are eliminated, and the sealing performance of the box is improved.

The horizontal climbing buckle is more convenient and faster to use than a screw and saves more space than a common buckle. Is an ideal locking device for closing the opening of the thin-wall box plate of the box.

Example 2:

the present example mainly introduces the structure of the insulation can, which is the introduction of the structure that the insulation board and the vertical and horizontal climbing buckle are added on the basis of the box in example 1, and the box is reversely folded by adopting a double-hole connecting piece.

Fig. 33 is an isometric view of the product of this example with the lid open, and fig. 40 is an isometric view of the product of this example after being folded back.

In fig. 33, the case bottom is in a closed state and the case lid is in an open state. The vertical and horizontal climbing buckles are in a buckling state. The left box plate 13, the rear box plate 1, the right box plate 4 and the front box plate 12 form a main structure of the length, the width and the height of the insulation box, an insulation cone plate 38 is fixed on the inner surface of each box plate through screws, and four edges of each insulation cone plate 38 are provided with 45-degree inclined planes. The front box cover 5 and the rear box cover 6, and the rear box bottom 9 and the front box bottom 8 are respectively provided with 1/2 long heat-preservation conical plates, and the integral heat-preservation conical plates are formed after the front box cover and the rear box cover are covered. The left box cover 2 and the right box cover 3 as well as the left box bottom 10 and the right box bottom 7 are positioned on the outer surfaces of the box bottoms of the front box cover and the rear box cover after the box is closed.

In fig. 34, the left box panel 13 covering the rear box panel 1 and the box lid bottom, which need not be reflected therein, are removed in order to clearly reflect the position of the male vertical hinge panel 32 after being folded back. The two-hole coupler 33 of the two-hole elbow U-shaped member 56 is rotated by 180 ° from the position shown in fig. 34 to the position shown in the figure, and at this time, the back plate of the two-hole coupler 33 is changed from the position facing the inside of the box shown in fig. 35 to the position facing the outside. The dual hole joint 33 connecting the rear and left box panels 1, 13 is retained in this view for clarity in reflecting the folded position of the dual hole joint 33. The right box plate 4 is attached to the outer surface of the front box plate 12 with the insulation cone plate 38 facing the outer side surface. As can be seen in the figures, the rear box panel 1 is formed by splicing together a vertical box panel 42 and a vertical box panel 32. The position of the male vertical button 36 is the same as that of fig. 33, except that the female vertical button body 35 is set back a distance to give a position for the male vertical button 36. Because the boxboard is the reverse folding this moment, the front of climbing the knot vertically and horizontally sticks to the surface of the left boxboard 13, the buckling of climbing the knot vertically and horizontally is inconvenient.

Fig. 35 shows the state of the vertical and horizontal climbers when just unfastened and the vertical box button has been retracted in the chute, and the vertical male-button flap 32 rotates around the vertical axis to separate the rear box board 1 into two pieces, namely the vertical female-button box board 42 and the vertical male-button flap 32, so that the box can be opened along the vertical direction of the rear box board 1. The box cover and the box bottom are not shown in the figure because the box cover and the box bottom are irrelevant to the opening and closing of the vertical and horizontal climbing buckles.

The connections between the left box plate 13 and the vertical box plate 42 and between the right box plate 4 and the front box plate 12 are double-hole elbow U-shaped members 56, and the double-hole connectors 33 can rotate in the range of 0-180 degrees around the vertical axis of the vertical U-shaped members 43. For clarity of illustration, the two double-headed elbow U-shaped members 56 are identified by the same part number 56.

As shown in FIG. 36, the position of the double-hole linkage 33 and the vertical U-shaped member 43 is shown when the incubator is unfolded, in which the crescent and the back plate are located on the Y-shaped side. Because of the blocking of the crescent and the reinforcing plate, the wide box plate can not continuously rotate towards the inner side of the insulation box and can only keep the mutually vertical position relation with the long box plate.

Fig. 9 is a schematic cross-sectional view taken at E-E of fig. 36, clearly showing the connection and positional relationship between dual-hole connector 33 and vertical clevis 43, where dual-hole connector 33 and vertical clevis 43 are perpendicular to each other.

As shown in fig. 37, which is the positional relationship between the dual-hole coupling 33 and the upright U-shaped member 43 when the incubator is folded back, the crescent is exactly opposite to the reinforcing plate and the Y-shape, and the dual-hole coupling 33 has been rotated 180 ° about the vertical axis of the upright U-shaped member 43, as compared with fig. 35. The outer surfaces of the left box board 13 and the vertical box board 42 after rotating and the outer surfaces of the right box board 4 and the front box board 12 after rotating are respectively attached to enable the inner surface of the box to be converted into the outer surface, the heat preservation cone board 38 fixed on the inner surface also turns outwards along with the rotation, and the larger thickness of the heat preservation cone board does not influence the reverse folding of the box. As shown in fig. 34, after being folded flat, the vertical male buckle loose-leaf board 32 is still butted with the vertical female buckle box board 42, and the vertical male buckle 36 is located at the empty position where the vertical female buckle body 35 exits.

Fig. 10 is a schematic sectional view taken along line F-F of fig. 37, clearly showing the perpendicular relationship of the dual aperture coupler 33 and the upright U-shaped member 43 when the incubator is folded back. In contrast to fig. 9, the two-hole coupling 33 has now been rotated 180 ° around the hole, with the back plate facing outwards.

The vertical female buckle body 35 and the vertical male buckle 36 are respectively arranged in the positioning sliding groove HH of the fixed frame 34 and the clamping groove of the vertical locking side piece 37, so that the male buckle and the female buckle can be accurately buckled. The installation and the use of the vertical and horizontal climbing buckle are convenient. The upper and lower inner side surfaces AA of the fixing frame 34 are matched with the upper and lower outer side surfaces CC of the locking edge piece 37 and the vertical inner side surface BB is matched with the front end surface DD of the locking edge piece 37, and the positions of the positioning sliding groove HH of the mounting vertical female buckle body 35, the clamping groove of the mounting vertical male buckle 36 and the positioning surface are relatively fixed, so that the positioning purpose can be achieved.

Fig. 64 is a schematic sectional view of the fixing frame 34 of fig. 8 taken along the line a-a, and includes a positioning slide groove HH having upper and lower side surfaces and a groove bottom surface KK. An inner groove-shaped shoulder type slideway is dug between the inner side of the part of the upper and lower two side surfaces close to the bottom plane of the fixed frame and the groove bottom KK and the limit table GG respectively. The outer shoulders on the two sides of the vertical female buckle body 35 are pressed in the shoulder type slide way to slide.

The fixing frame 34 is a support EE near the opening, and is a process column for preventing the deformation of the opening of the frame. It is necessary to make a space to accommodate support EE on the back of insulating plate 38 or at the corresponding positions of vertical pin 36 and vertical lockrand 37. The size and position of the support EE are determined so as not to interfere with the sliding position of the vertical female buckle body 35 and not to affect the buckling of the vertical male buckle 36. The back surface FF is provided with a Y-shaped structure which is a soft box plate connected with the back surface FF and plays a role in connecting and reinforcing the fixed frame 34. The rivet and the straight pressing plate are used for assisting in connection. For simplicity of the drawings, the Y-shaped structure coupling method of the rear face FF of the fixing frame 34 is not shown in fig. 33, 34, 35, and 38.

As shown in FIG. 31, the vertical female buckle body 35 is provided with external shoulders at both sides. Fig. 32 is an isometric view of the vertical button body 35. The inner shoulders are matched with the inner shoulders on two sides of the positioning sliding groove HH of the fixing frame 34 in a sliding way, the inner shoulders are not communicated with BB surfaces, and the non-communicated parts form a limiting table GG so as to prevent the vertical female buckle body 35 from slipping and play a role in positioning. That is, when the vertical female buckle body 35 is located at the position of the limit, the vertical male buckle body can be accurately buckled with the vertical male buckle 36.

The vertical button body 35 of fig. 32 has no rivet holes and U-shaped slots in the tail portion and has more external shoulders on both sides than the button body 26 of fig. 24.

Fig. 38 is an isometric view of the box panel 42 with the vertical snaps retracted along the slot, in this case the rear panel 1, and vertically cut along the open end side II of the frame 34. There is a fixed frame 34 and two vertical female buckle bodies 35. The fixing frame 34 is connected to the Y-shaped double-bevel removed plate of the upper and lower U-shaped members by rivets 19. The vertical female buckle body 35 is mounted in the slide groove and slides on the back of the insulation cone plate 38. The insulation cone plate 38 is fixed to the inner surface of the rear box plate 1 by screws 41, and the number and positions of the screws 41 are not shown in the drawing.

The vertical shaft is connected in series in the hole of the long vertical U-shaped piece of the right box plate 4, and the buckling and the unbuckling are completed by rotating around the vertical shaft. The flap U-shaped element 58 is here the wide upright U-shaped element of the rear box panel 1.

Fig. 17 is a schematic cross-sectional view of the front box board 12, which is a simplified structure of the front box board 12, and the front box board 12 is treated as an integral part, and the structure is not shown in detail in the cross section. The four sides of the heat preservation cone plate 38 are all inverted by 45 degrees to form a cone with 45 degrees at the four sides. The bottom of the cone is a section of regular cuboid. The different sizes of the box boards are different because the shapes of the box boards are the same, and the sizes of the box boards are different. And thus all use the same part number. Because general heat-insulating materials are softer, defects and damages are easily caused in use. The heat insulation board 38 is entirely covered and protected by the covering member 40. The service life of the device is prolonged. The disk of the disk nut 39 is as large as possible, the soft insulation cone plate 38 is pressed by the enlarged area, and is tightened and fixed by a screw 41, and the screw 41 is generally fixed on the reinforced support rib plate.

The elastic sealing member 57 is used for eliminating a gap generated between the abutting surfaces of the two insulation boards due to manufacturing errors, and is attached to the four inclined surfaces of the insulation cone plate 38 in the groove for installing the elastic sealing member 57, so that the gap is eliminated, and the sealing and heat insulation performance is improved. The resilient seal 57 is not shown in the other figures.

Fig. 18 is a cross-sectional view of the groove of the double hole coupling 33, and the double hole coupling 33 is a key structural member for switching between inside and outside of the incubator. The double-hole connector 33 is formed by connecting two circles with the same diameter and the same wall thickness in a tangent manner at the center and connecting the two circles by two common tangents. Similar to a butt joint of two U-shaped bodies. The two bores are of equal diameter to the shaft 11. The concave section of the part connected with the vertical U-shaped piece 43 is formed by rotary cutting with a circular milling cutter with the diameter equal to the wall thickness, and three crescent shapes needing to be folded are removed along the central line of the two circles, so that the excircle of the convex section of the vertical U-shaped piece 43 can rotate in the groove, and the rest convex sections are left in crescent connection. A reinforcing plate with a width smaller than the wall thickness 1/2 and a proper thickness, also called a back plate, is added on the back of the crescent to penetrate through one side surface of the whole double-hole connecting piece 33 so as to enhance the connecting strength of the crescent. The hole without crescent is connected in series with the shaft 11 in the hole of the vertical U-shaped piece 43 to form a fixed hole. The other hole with the crescent is a movable hole and is stringed in the wide vertical U-shaped part hole of the wide box plate, and one side with the crescent is positioned on the inner side surface of the box. The movable hole can rotate around the fixed hole shaft within the range of 0-180 degrees. Thereby realizing the mutual conversion of the inside and the outside of the long box board and the wide box board of the box.

The upwardly convex block in fig. 18 is the back plate, which is used to increase the crescent strength and function as an auxiliary link.

The box of the embodiment is convenient in that the box can be reversely folded, and is slightly complicated compared with the box of the embodiment 1 that the box can be folded when being used for one time. But compared with the existing polyester foaming incubator which cannot be folded, the folding incubator is advanced.

Each air bag group consists of a plurality of air bags and an air passage Q, and the air bags are connected and communicated with each other through the air passages Q. The tail of the valve 44 is bonded between the upper and lower bladder halves 54, 55. As shown in fig. 41 and 42, the head of the valve 44 is fitted into the circular hole of the elbow U-shaped member 21 a little above the plane thereof. The end angle of the long cap U-shaped member 25, which interferes with the mounting of the head of the valve 44, is removed in a portion slightly larger than the head of the valve 44, facilitating the operations of air intake, closing and air exhaust of the valve 44. The valve 44 is a standard component and is used only here, and its structure will not be described.

As shown in fig. 44, the box is divided into six inner surfaces of front and back, left and right, and cover and bottom, four air bag groups are needed for each of the length and width, four air bag groups are needed for the left and right halves of the cover and bottom, a total of eight air bag groups are formed into an air bag assembly 45, and the air bag groups are connected with each other by air passages Q. The air bag groups of the box cover and the box bottom are respectively communicated with the air bag group of the wide box plate. The valve 44 is mounted on the head bag of the left box panel bag bank 46. The front box cover air bag group 48 and the front box bottom air bag group 49 are respectively positioned at the upper end and the lower end of the front box plate air bag group 47 and are communicated with the air bag groups through air passages Q. The right box panel airbag group 50 communicates only with the front box panel airbag group 47 and the rear box panel airbag group 52 with the air passage Q. The rear box cover air bag group 51 and the rear box bottom air bag group 53 are respectively positioned at the upper end and the lower end of the rear box plate air bag group 52 and communicated with the air bag groups through air passages Q. The left panel airbag group 46 communicates only with the front panel airbag group 47 via the air passage Q. Round through holes distributed at four corners of the air bag group are used for fixing the air bag group.

As shown in fig. 42, the air bag module 45 is simply installed in the case, and first, the left case panel air bag unit 46 with the valve 44 is installed in the concave of the left case panel 13, and the valve 44 is fixed to the mouth of the fixed circular hole after passing through the hole between the fixed circular hole and the Y-shape of the bent U-shaped member 21. As shown in fig. 45, the Y-shape of the long transverse U-shaped member 20 is offset laterally outward by a distance sufficient to accommodate the deflated thickness of the balloon. The Y-shapes of the four U-shaped parts forming the box board frame are all offset by the same distance, and then concave pits for installing the air bag groups are formed. The straight pressing plate 16, the rivet 19, and the outer panel 29, the flat-topped corrugated sheet 30, and the inner panel 31 constituting the hose sheet 17 are all simultaneously offset by the same distance along the Y-shape. A plurality of clamping grooves which correspond to the fixing hole positions on the air bag groups and can be inserted with rubber nails are arranged in the pits, the rubber nails are penetrated through the fixing holes of the air bag components 4, the rubber nails are inserted into the corresponding clamping grooves, the other air bag groups are sequentially fixed in the corresponding box plate pits by the same method, and the installation of the air bag components 45 in the box is finished smoothly. The air bag box capable of being repeatedly inflated and deflated is formed, when the air bag box is required to be used, the box is unfolded, the screw cap for blocking the air nozzle opening on the air nozzle 44 is unscrewed, the air bag is inflated, the air nozzle is still blocked by the screw cap after the air bag is filled to be qualified, and then articles are put in the air bag box and the box is sealed. After the air bag box is used, the screw cap of the inflating valve 44 is unscrewed, the valve in the inflating valve 44 is pressed down to release the gas in the air bag, the air faucet is sealed by the screw cap, and the air bag box is folded and stored for later use. The rubber nail has certain elasticity and can stretch out and draw back along with the inflation and deflation of the air bag group, thereby achieving the purpose of dynamically fixing the air bag group.

The deflated air bag groups return to respective pits under the action of the tensile force of the rubber nails, and the folding of the air bag box is not influenced. The folding method is the same as example 1, and the folded shape is the same as example 1 and fig. 2.

The inflatable air bag is formed by bonding a common material and an air bag, wherein the common material and an elastic material are bonded to form a single-side inflatable air bag, the structure of the single-side inflatable air bag is basically the same as that of the inflatable air bag formed by bonding double-layer elastic materials, and the common material without elasticity also has certain bending performance so as to be convenient for connecting air passages between the air bag groups and turning along with the box plate.

Regarding the case that adopts the shock attenuation board, if the shock attenuation board is installed in the pit, its thickness does not influence folding, can adopt the case structure of example 3. If the thickness affects folding, the box structure of example 2 is used. The structures are the same and different, and detailed description is omitted.

Example 4

The embodiment is a simple introduction of the structures of the telescopic box cover, the box cover without the horizontal climbing buckles and the self-balancing horizontal climbing buckles.

For some boxes with larger difference in length and width, the box bottoms of the front box cover and the rear box cover are folded to be much longer than those of the left box cover and the right box cover, so that stacking and packaging are influenced. Therefore, the extension portion is retracted to form a telescopic structure. Especially insulation can, damper box and gasbag case, the left and right case lid bottom of the case will exchange the position with preceding, back case lid bottom of the case in many times, because sometimes with heated board, damper plate and gasbag assembly at the left and right case lid bottom of the case probably more suitable. The front cover and the back cover which are arranged on the outer layer of the box can be made into a telescopic cover and a telescopic box bottom.

The box is sealed by horizontal climbing buckles at the mouth parts of the left box cover bottom and the right box cover bottom on the outer layer, while the front box cover bottom and the rear box cover bottom on the inner layer do not need to be sealed by horizontal climbing buckles, and the structure of the box cover without the horizontal climbing buckles is adopted.

For empty boxes, half boxes and boxes with more virtual objects, the box cover may collapse, thereby affecting the buckling of the horizontal climbing buckle. At the moment, a self-balancing device is added to the horizontal climbing buckle.

(1) Telescopic box cover

Fig. 49 is a schematic front view of a square hole edge sealing member 61, in which a plurality of rectangular through holes are formed in the front surface of the edge sealing member, and the number of the through holes is determined according to the length of the edge sealing member. The T-shaped strip 60 is a narrow strip with one end replacing a round hole and the other end replacing a left shoulder and a right shoulder, the width and the thickness of the T-shaped strip are the same as the length and the width of the rectangular through hole, and the length of the T-shaped strip is related to the size of the telescopic size of the box cover.

Fig. 50 is an isometric view of the T-bar 60 inserted into the square hole sealing member 61 with the alternate hole end of the T-bar 60 outboard of the square hole sealing member 61 and the alternate shoulder end on the same side as the Y-shaped structure. The T-bar 60 is intended to slide easily in the rectangular through hole.

Fig. 46 is a front view schematically showing the front cover when the front cover is opened, and fig. 47 is a front view schematically showing the front cover when the front cover is retracted, and the structure of the pressing plate, the soft case plate and the rivet is not shown. Flat-top corrugated board can be eliminated for soft box board for small boxes and removed for larger boxes at the shoulder sliding portion of the T-bar 60. The non-beveled lockstitching member 66 eliminates the need for beveled edges at both ends because the Y-shaped structure is no longer coupled to the frame. The male buckle is arranged in the two positioning clamping grooves of the non-bevel-edge locking piece 66, the head of the T-shaped strip 60 instead of a round hole is arranged in a corresponding small square notch on the Y-shaped structure, and the small square notch is specially used for installing the T-shaped strip 60. And fixed by a pressing plate and a rivet. The frame of the front cover is the fixed portion and the non-beveled serging member 66 and the male buckle are the movable portions. It is stretched when used and shortened when folded.

The structure of the telescopic front box bottom is the same as that of the telescopic front box cover, and the structures of the telescopic rear box cover and the box bottom are the same as that of the telescopic front box cover except that the female buckle is arranged in the non-bevel-edge lockrand piece 66.

A gap is arranged between the T-shaped strips at the bottom of the telescopic box cover, and the left box cover bottom and the right box cover bottom are buckled by a horizontal climbing buckle, so that the sealing performance of the box is not influenced.

(2) Non-horizontal climbing buckle box cover

Fig. 48 is a partial sectional view showing the front cover 5 and the left cover 2 without the flat climbing buckle, and the opening of the front cover 5 is closed by the elongated groove U-shaped member 65 instead of the locking edge member. Fig. 54 is a schematic top view of the elongated slot U-shaped member 65, with the two ends of the Y-shape having a 45 ° bevel and male and female positioning teeth, and the U-shape adjacent the two ends having a groove therein for receiving the straight tooth 64. However, the middle part of the length of the long groove U-shaped piece 65 is overlapped with the buckling parts of the horizontal climbing buckles of the left box cover and the right box cover, and the straight buckle teeth 64 cannot be installed. A narrow rectangular through hole is formed between the bottom of the groove and the Y shape, a thin rectangular body is arranged between the bottom of the groove and the narrow rectangular through hole, and the middle part of the thin rectangular body can deform and give way to the direction of the narrow rectangular through hole after being pressed. Fig. 55 is a front view of the straight tooth 64, which is a U-shaped flat mouth with a square vertical tooth added to the flat mouth of the flat mouth instead of a cone.

Fig. 56 is an isometric view of the straight-buckled tooth 64, a semi-circular arc structure with a radius R2 is added to the middle circular arc part of the straight-buckled tooth 64, the R2 is larger than the size of the "U" -shaped R1, a plane tangent to the R1 circular arc is formed at the top and left side of the R2, and a vertical plane tangent to the R2 is added at the right side. Fig. 19 is a partial sectional view of the straight-toothed portion 64 when it is erected, and the straight-toothed portion 64 is integrally penetrated with the long-groove U-shaped member 65 by the shaft 11. The left vertical surface of the straight tooth 64 abuts against the bottom surface of the groove of the long groove U-shaped member 65, and the distance between the bottom surface of the groove and the center of the inner circular hole of the straight tooth 64 is equal to R1. Because the size of R2 is bigger than that of R1, the bigger vertical surface part can block the rotation of the straight tooth 64 to the outside of the groove, and the straight tooth can only rotate to the outside of the groove after the middle part of the thin cuboid is pressed and deformed to the narrow and long through holes to give way. The added vertical surface on the right side is an anti-misoperation arrangement that prevents pulling in the opposite direction when straightening the tooth 64 is cocked.

As shown in fig. 48, a long hole pressing plate 63 and a long hole Y-shaped member 62 as rectangular through grooves are provided on the left cover 2 at a position overlapping with the square vertical teeth of the straight tooth 64 of the front cover 5, and the double-inclined pressing plate 18 is positioned on the outer side surface and fixed by riveting with a rivet 19. The square vertical teeth of the straight buckling teeth 64 are inserted into the through grooves of the rectangular holes to limit the movement of the front box cover 5, so that the front box plate is pulled to achieve the purpose of preventing the front box cover from being exposed. The connection of the long groove U-shaped piece 65 and the soft box plate of the front box cover 5 also uses two straight pressing plates 16 to press the inner and outer panels of the soft box plate in the Y-shaped groove and uses the rivet 19 to rivet and fix.

A long hole pressing plate 63 and a long hole Y-shaped member 62 which are rectangular through grooves are also arranged on the right box cover 3 at the same position as the left box cover 2.

Fig. 53 is an isometric view of the straight buckle teeth 64 in the vertical position, where the two vertical straight buckle teeth are inserted into the through slot of the rectangular hole of the left case cover 2 on the left side and into the through slot of the rectangular hole of the right case cover 3 on the right side.

The structures of the long groove U-shaped pieces 65 and the straight buckle teeth 64 of the other front box bottom, the rear box cover and the rear box bottom without the horizontal climbing buckles are the same as the structure of the front box cover 5, and the structures and the installation and the fixation of the long hole pressing plates 63 and the long hole Y-shaped pieces 62 of the right box cover, the left box bottom and the right box bottom are the same as the structures and the installation and the fixation of the left box cover 2.

FIG. 51 is a partial cross-sectional view of the flat plate 64 of the straight tooth of example 4, and FIG. 52 is an isometric view of the flat plate 64. The circular arc top plane of the straight cog 64 abuts against the groove bottom surface of the long groove U-shaped member 65, because R2 constituting the circular arc top plane is larger than R1. The straight-tooth 64 presses the thin rectangular parallelepiped whether it is rotated upward or downward. The structure mainly prevents the straight buckle teeth 64 from freely swinging, so that the boxes can be stacked and leveled after being folded. The straight buckle teeth 64 are also designed to prevent free swinging when erected, so as to facilitate insertion into the through grooves of the corresponding rectangular holes.

The mouth parts of the box bottoms of the front box cover and the rear box cover without the horizontal climbing buckles can not be closed, and the sealing performance of the box is not influenced because the box bottoms of the left box cover and the right box cover are buckled by the horizontal climbing buckles.

Fig. 62 is a schematic top view of a self-balancing horizontal climbing buckle, in which a self-balancing device of the horizontal climbing buckle is located outside two clamp arms, and has a spacing distance from the clamp arms, so that the self-balancing device does not hinder the swing of the clamp arms. Fig. 63 is an isometric structural view of the self-balancing buckle, which is composed of four parts, namely a self-balancing male buckle 68, a self-balancing female buckle body 67, a buckle pressing plate 27 and a buckle shaft 28. The self-balancing female buckle body 67 and the buckling plate 27 are connected in series by the buckling shaft 28 to form the self-balancing female buckle. The self-balancing male buckle 68 and the self-balancing female buckle are called self-balancing climbing buckles.

Fig. 57 is a front view structural diagram of the self-balancing female buckle body 67, fig. 59 is an isometric structural diagram of the self-balancing female buckle body 67, and the self-balancing female buckle body 67 is symmetrically distributed along a center line between the left and right surfaces. The left side and the right side of the front platform surface are respectively provided with a narrow rectangular body which is longer than the front platform and is a self-balancing device of a self-balancing female buckle body and a self-balancing male buckle.

Fig. 58 is a schematic front view of the self-balancing male buckle 68, fig. 60 is a schematic isometric view of the self-balancing male buckle 68, and the outer sides of the two clamp arms are provided with a narrow vertical through groove and a sunken step with the same thickness as the front platform, which is a self-balancing device of the self-balancing male buckle and the self-balancing female buckle body.

As shown in fig. 61, the narrow rectangular body is pressed against the depressed step, and a large gap is formed between the front end surface of the narrow rectangular body and the inner vertical surface of the depressed step, in order to prevent interference at the time of engagement. As shown in fig. 62 and 63, a pair of latch arms press against the front deck. The pressing and the supporting are mutually realized, and the balance is achieved.

The four examples are different in application, but the basic structure is the same. Examples 2 and 3 are modifications of example 1, and example 4 is a supplement to the deficiencies of the three box structures described above. From the same structure, a frame, a soft box plate and a horizontal climbing buckle; the same idea, cyclic utilization, reduce rubbish. The existing materials and technologies are fully utilized, and the pollution and waste at present are solved as much as possible.
