Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1 to 2, the multi-joint hinge frame folding turnover box of the invention comprises a box body 100, a corner hinge group 200 and an edge hinge group 300.

The box 100 includes twelve base plates, and twelve base plates form the box structure of a cuboid, wherein four base plates are as four curb plates of cuboid, and eight base plates are connected respectively at the last lower extreme of four curb plates and all inwards fold in order to form the top surface and the bottom surface of cuboid in addition, and the top and the bottom of the box structure of cuboid form by four base plate overlap, and the base plate of double-phase offside is in the box with the base plate of double-phase offside is impressed in addition. The two connected substrates can be folded around the borderline formed by the connection, that is, the sides of the box 100 are all formed by connecting the two substrates, and the substrates can be folded and rotated around the common borderline. It is contemplated that the folding between the substrates may be accomplished by indentations formed in the joints, or by other types of joints such as hinges that are capable of rotating about an axis.

The eight corner hinge groups 200 are respectively disposed at eight corners of the box body 100, and each of the eight corner hinge groups includes four first fixing plates 210, the four first fixing plates 210 are respectively fixed on four base plates at corresponding corners, each corner is correspondingly provided with four base plates, which are two side plates and a base plate connected to upper ends or lower ends of the two side plates. In the same angular hinge group 200, two first fixing plates 210 corresponding to two connected base plates are sequentially hinged and connected through two first hinge plates 220, that is, the two first fixing plates 210 located on the same angular hinge group 200 and respectively fixed on the two connected base plates are connected through the first hinge plates 220, specifically, the two first hinge plates 220 are hinged and connected, and one side of each of the two first hinge plates 220 opposite to each other is hinged with one first fixing plate 210. In addition, in the same corner hinge group 200, the hinge axes of the three hinges between the two connected first fixing plates 210 are parallel to the corresponding side lines, and the corresponding side lines are the side lines formed by connecting the two base plates fixedly connected to the two first fixing plates 210 respectively. Specifically, the hinge axes between the two pairs of first fixing plates 210 and the first hinge plates 220, and the hinge axes between the two first hinge plates 220 are parallel to the side line formed by the two base plates corresponding to the two first fixing plates 210. Because the three hinge axes are parallel to the corresponding side lines, when the first fixing plates 210 rotate along with the folding of the substrates, the two connected first fixing plates 210 cannot cause structural interference due to relative position change, so that the folding between the substrates becomes smooth.

Twelve side hinge groups 300, namely, the corner hinge groups 200 on the eight corners are connected in series to form a rectangular frame, and twelve side lines of the box body 100 are wrapped, and the rectangular frame formed by the side hinge groups and the corner hinge groups can bear load, can share the load of the substrate and the folding joint of the substrate, reduce the stress of the joint of the substrate and the substrate, and indirectly improve the connection strength of the folding joint; in addition, the side lines and the corners are coated, so that the direct external force impact on the turnover box is avoided, and the service life and the structural strength of the turnover box are improved. Even if the folding sidelines are broken, the turnover box can still keep the shape of a cuboid and be normally used due to the action of the cuboid frame.

Referring to fig. 6 to 8, in some embodiments of the present invention, each of the side hinge sets 300 includes two second fixing plates 310 and two second hinge plates 320, and each of the borderlines formed by the two base plates corresponds to one of the side hinge sets 300. In the hinge group 300 on the same side, two second fixing plates 310 are respectively fixed on two base plates corresponding to the side line, the two second fixing plates 310 are sequentially hinged and connected through two second hinge plates 320, specifically, the two second hinge plates 320 are hinged and connected, and one side of the two second hinge plates 320 opposite to each other is hinged with one second fixing plate 310 respectively. In addition, in the hinge group 300 on the same side, the hinge axes of the three hinges between the two connected second fixing plates 310 are parallel to the corresponding side line, that is, the hinge axes between the two pairs of second fixing plates 310 and the second hinge plates 320, and the hinge axes between the two second hinge plates 320 are parallel to the side line formed by the two corresponding base plates of the two second fixing plates 310. Because the three hinge axes are parallel to the corresponding sidelines, when the second fixing plate 310 rotates along with the folding of the base plate, the two connected second fixing plates 310 cannot cause structural interference due to relative position change, so that the folding between the base plates becomes smooth. Although the relative position of the second fixing plate 310 is changed with the two basic folding, the two second hinge plates 320 are relatively rotated to adapt to the position change of the two second fixing plates 310 due to the hinge action of the two second hinge plates 320, thereby realizing the movable connection between the second fixing plates 310. As can be seen from the above, the edge hinge set 300 and the corner hinge set 200 are connected by a four-plate three-axis connection, which uses the hinge connection of the middle two hinge plates to realize the rotation and position change between the fixed plates.

Specifically, the first fixing plate 210 is provided with a first riveting hole 211, the second fixing plate 310 is provided with a second riveting hole 311, and both the first fixing plate 210 and the second fixing plate 310 are fixed on the substrate by riveting.

Specifically, as can be seen from fig. 6 to 9, the side hinge sets can be divided into three side hinge sets in the height direction, the length direction and the width direction, and are formed by connecting two second fixing plates 310 and two second hinge plates 320, and the length of each side hinge set is determined according to the size of the box 100. In addition, the hinge joint of the first fixing plate 210 and the first hinge plate 220, the hinge joint of the first hinge plate 220 and the first hinge plate 220, the hinge joint of the second fixing plate 310 and the second hinge plate 320, and the hinge joint of the second hinge plate 320 and the second hinge plate 320 are realized by inserting the hinge shaft through the matching of the concave part and the convex part, both ends of the hinge shaft are connected with limiting structures for limiting the axial displacement of the hinge shaft along the hinge shaft, for example, both ends of the hinge shaft protrude to the outside and are in threaded connection with limiting nuts, so that both ends of the hinge shaft can be limited. The number and arrangement design of the concave and convex parts can be selected according to actual conditions, and are not limited herein. In order to better coat the sidelines by the side hinge group 300 and reduce the connection gap in the side hinge group, even if the folded part of the substrate is torn, the solid articles can be well loaded by the small connection gap of the side hinge group 300, the articles are prevented from falling from the self gap of the side hinge group 300, and the normal use of the turnover box is ensured after the substrate is torn and disconnected. In some embodiments, the first hinge plate 220 and the second hinge plate 320 sharing the hinge shaft are touch-fitted to further reduce the gap.

Referring to fig. 2 and 4, in some embodiments of the present invention, three hinges between two connected first fixing plates 210 and three hinges between two connected second fixing plates 310 on the same side line share three hinge axes. That is, on the same side line, the hinge axes of the three hinges on the two first hinge plates 220 and the three hinges on the two second hinge plates 320 are collinear in one-to-one correspondence, and share a hinge shaft. Through sharing the articulated shaft, can reduce spare part, simplify the structure, can also transmit the effort in addition, make the atress more balanced, avoid certain position stress too concentrated and lead to this position to damage, improve the life-span of turnover case.

Referring to fig. 4, in some embodiments of the present invention, the first fixing plate 210 and the second fixing plate 310 corresponding to the same edge and fixed on the same substrate are connected to achieve synchronous rotation, and the first fixing plate 210 and the second fixing plate 310 rotate synchronously, so that the first fixing plate 210 and the second fixing plate 310 fixed on the same substrate and on the same edge do not rotate and shear the substrate, which damages the substrate, and also can avoid local stress deformation, even stress, and improve structural strength and load. Specifically, the second fixing plate 310 has arc protrusions 313 protruding outward at the upper and lower ends thereof, and the first fixing plate 210 has grooves 213 correspondingly matching with the arc protrusions 313, such that the first fixing plate 210 and the second fixing plate 310 rotate synchronously, and the rotation of the first fixing plate 210 drives the rotation of the second fixing plate 310, or vice versa. Therefore, the stress of the first fixing plate 210 can be transferred to the first fixing plate 210 and the second fixing plate 310 on the whole sideline, so that the stress is not concentrated, the acting force can be transmitted, the stress is more uniform, the local stress is reduced, and the stress is not easy to damage.

Referring to fig. 5, in some embodiments of the present invention, twelve substrates are two long side plates 110, two short side plates 120, four long cover plates 111, and four short cover plates 121, respectively, the long side plates 110 and the short side plates 120 are connected in a staggered manner to form a rectangular closed profile, the upper and lower edges of the two long side plates 110 are connected to one long cover plate 111, and the two top long cover plates 111 and the two bottom long cover plates 111 can be spliced to seal the upper and lower openings of the closed profile to form a rectangular box-shaped structure; the upper and lower edges of the short side plate 120 are connected with a short cover plate 121, the short cover plate 121 is covered and pressed into the box body 100 by the long cover plate 111 and is attached to the corresponding long cover plate 111, and when the box body 100 is in a cuboid state, two substrates of each side line are in a vertical state. The short cover plate 121 is covered by the long cover plate 111, and in order to enable the short cover plate 121 to be connected with the corresponding first fixing plate 210 and the second fixing plate 310, the two sides of the long cover plate 111 are provided with abdications 112, and the abdications 112 are used for connecting the short cover plate 121 with the corresponding first fixing plate 210 and the corresponding second fixing plate 310.

It is understood that in some embodiments of the present invention, the box 100 is formed by folding a whole plastic corrugated board by pressing, and during manufacturing, the board shape of the box in a spread-out state is formed by cutting a large plastic corrugated board, and then each foldable side line is formed by pressing the pressing mark, since the closed contour is formed by surrounding a spread-out board, the connection between the long side board 110 and the short side board 120 is not formed naturally, i.e. the long side board 110 and the short side board 120 are disconnected, and need to be connected by gluing, rivets, etc., for example, the long side board 110 and the short side board 120 at both ends need to be connected to form the closed contour, and there is a length left from the folding line for the long side board 110 or the short side board 120 to be connected, and the left length is used for being attached to the short side board 120 or the long side board 110 to be connected and connected by rivets. Adopt the folding box of plastics corrugated sheet preparation, simple manufacture, it is with low costs, be suitable for big preparation in batches, but the plastics corrugated sheet is folded through the indentation folding line, its folding joint department is very fragile, easy damage, and this application utilizes the reinforcement and the protection of the cuboid frame that angle hinge group 200 and limit hinge group 300 are constituteed, make the turnover case to the preparation of plastics corrugated material have the effect that fine structure is strengthened, the cuboid frame can independently bear the load, also can share the load for base plate and indentation folding sideline department, reduce the tearing possibility of plastics corrugated sheet indentation folding department, the turnover case life-span is prolonged.

Referring to fig. 1 to 3, the two corresponding long cover plates 111 have reinforcing blocks 400 mounted at the splicing ends of the outer surfaces thereof, which are aligned with each other, that is, the reinforcing blocks 400 are mounted at the splicing ends of the outer surfaces of the two corresponding long cover plates 111 at the top, and the reinforcing blocks 400 are mounted at the splicing ends of the outer surfaces of the two corresponding long cover plates 111 at the bottom. The aligned reinforcing blocks 400 are provided with aligned through holes 410, and connecting structures 420 are inserted into the aligned through holes 410 to maintain the aligned reinforcing blocks 400 in an aligned split state. It will be appreciated that the connecting structure 420 may be a plastic tie that is threaded through the two through holes 410 and tightened externally so that the two reinforcing blocks 400 are maintained in an aligned split condition. Of course, in other embodiments, the connection structure 420 may also be an insertion rod, and after the insertion rod is inserted into the through hole 410, both ends of the insertion rod protrude out of the through hole 410 and are connected with a limit nut through threads, so as to achieve the same effect, and the insertion rod bears a larger load and is more suitable for loading heavy objects.

In some embodiments of the present invention, the reinforcing blocks 400 are flush with the first fixing plate 210 and the second fixing plate 310 on the corresponding long cover plate 111 in a height direction, which is a vertical direction, so that the reinforcing blocks 400 at the bottom can bear gravity, the central position of the bottom of the box 100 is not suspended, and the deformation of the middle portion is reduced. In addition, since the short cover plate 121 is lower than the long cover plate 111, in order to enable the short cover plate 121 to bear part of the gravity load, the first fixing plate 210 fixed to the short cover plate 121 is provided with a first protrusion 212 protruding outward, the second fixing plate 310 fixed to the short cover plate 121 is provided with a second protrusion 312 protruding outward, and the first protrusion 212 and the second protrusion 312 are flush with the first fixing plate 210 on the long cover plate 111 corresponding to the side. Thus, the gravity load distribution of the whole turnover box is more uniform at the bottom.

In some embodiments of the present invention, two sides of the short cover plate 121 are attached to the inner surfaces of the long side plates 110 located at two sides of the short cover plate 121, so that the short cover plate 121 can support the long side plates 110 at two sides to better maintain the rectangular parallelepiped state of the box body.
