Detachable and expandable spliced plate type turnover box with damping system

Technical Field

The invention belongs to an express transfer box, in particular to an express transfer box which can be disassembled into a plane panel, can be quickly clamped and restored, is internally provided with light objects of a combined type air bag for filling and is lighter, and is particularly suitable for express delivery.

Background

A container for express delivery, especially a container for express delivery, is desired to have a container which can be expanded and reduced in the total volume and capacity of the contents and to use no or less shock-absorbing filler for the contents.

The prior art relates to a transfer container with a small and expandable total volume capacity of the contained goods, as follows:

the Chinese patent 201120196875.5 Tianjin Shuizhun plastic products Limited company discloses a hollow plate turnover box, which is a large turnover box divided into a plurality of small box units. The disadvantages are that: firstly, the large turnover box and the small turnover box exist simultaneously, and the small turnover box cannot be used singly.

Chinese patent 200910261597.4 Yangguang discloses a split-type turnover box, which is a folding turnover box composed of six panels, and a multi-turnover box split-type structure using the turnover box as a unit. The disadvantages are that: firstly, structural components of the turnover box are too complex, secondly, the appearance size of the large turnover box formed by splicing multiple turnover boxes is enlarged, and the space in the large turnover box is still an independent space of a small turnover box, namely, the large turnover box cannot be filled with large articles.

The prior art relates to the use of no or little shock-absorbing filler, such as the following three items:

chinese patent 201520419050.3 hunan ao pie automation equipment limited company discloses a "theftproof turnover case with internal positioning function", the top surface of case lid is equipped with the locating piece, the bottom surface of case lid is fixed with the gasbag, the top surface of case lid is equipped with the inlet end and the end of giving vent to anger that communicate with the gasbag respectively, the edge of case lid is equipped with the magnetism pickproof lock with turnover case opening lock.

Chinese patent 201420185096.9 Henan province tobacco company Job's city company discloses a "tobacco turnover case", including case lid, lateral wall and bottom plate all around, lateral wall inner wall indent all around, the indent position be equipped with the gasbag, the gasbag four corners be fixed in the four corners of inner wall, the lateral wall be equipped with the through-hole, the inflation and deflation hole of gasbag be fixed in the through-hole.

The Chinese patent 201610583735.0 Suzhou Xinlichang electronic material limited company discloses a plastic circulation box with an air cushion, which is characterized by comprising a plastic circulation box body, cross partition plates, air bags, inflating valves and a simple treading type inflating pump, wherein the cross partition plates are arranged inside the plastic circulation box body, the air bags are attached and fixed on the surfaces of the cross partition plates, the inflating valves are arranged on the edges of the cross partition plates and connected with the air bags, and the simple treading type inflating pump is arranged between the cross partition plates and connected with the inflating valves.

The disadvantages of the three aforementioned shock absorbing bladder patents are: the turnover box can not be disassembled, so that the turnover box material is inconvenient to recycle in a volume reduction mode; the turnover box can not be spliced to enlarge or reduce the volume, but can not reduce or increase the gap between the air and the articles in the turnover box; each gasbag independently makes and aerifys the number of times many, and it is inconvenient as emerging express delivery trade use now, and each gasbag independently makes the turnover case built-in article can not be placed in the middle, easily damages built-in article in the transport.

Traditional mortise and tenon structure can not be as the reason that inner space dilatation turnover case: traditional mortise and tenon structure always blocks in mortise or mortise groove entirely in the tenon, but realize that 2 apron backs are expanded into to the curb plate that a volume unit used and the parallel of apron, when 2 apron were enclosed into the box body to the curb plate that originally was used for a volume unit used, 2 curb plates that even become the coplanar concatenation always were shorter than 2 apron that become the coplanar concatenation, make its curb plate that originally was used for a volume unit used, can not be used for the synthetic turnover case of 2 apron of coplanar concatenation. And (4) conclusion: the traditional full-clamping mortise and tenon structure can not be used for synthesizing a unit turnover box with 4 side plates and 2 cover plates only by using two plate types, namely a side plate and a cover plate, but also can be used for connecting 2 cover plates spliced on the same plane into a large hollow expansion turnover box in a mortise and tenon manner; in a word, the traditional full-clamping type mortise and tenon structure only uses two plates, namely a side plate and a cover plate, can only splice the unit turnover box, and cannot be expanded into a turnover box with a large inner space formed by combining multiple units.

The principle that the traditional mortise and tenon can not expand the turnover box is as follows: as shown in fig. 18, it can be seen from the reason that the conventional mortise and tenon structure cannot be used as an expansion turnover box in the background art, the conventional mortise and tenon structure is that the tenons are all in the mortise and tenon, and one group of mortise and tenon structures only have one mortise and tenon connection mode, and one mortise and tenon connection mode only has one connection size. And a unit turnover box of the turnover box which can be expanded and a plurality of unit combination turnover boxes which can be expanded require that the side plates are spliced into different splicing lengths, so that only one connecting size of a traditional mortise and tenon connecting mode cannot be used for splicing one side plate into one unit turnover box, and a plurality of unit combination turnover boxes can be spliced.

The upper drawing of fig. 18 shows that the turnover box is spliced by the spliced side plates 1 of the invention, but the spliced side plates 1 are connected in a full-mortise and tenon seamless and seamless non-hollow clamping mode by the traditional mortise and tenon, and the connection length of the two spliced side plates 1 is shorter than the connection length 2a of the two upper cover plates and the lower cover plates 3 by c/2, so that the turnover box which is not expanded by the spliced side plates 1 of the invention can only be connected into a turnover box with 2a being 2b +3c-c/2, the invention purpose cannot be realized, and the turnover box which is not expanded by the traditional mortise and tenon seamless and non-hollow clamping mode by the traditional mortise and tenon can not be realized.

As shown in the lower drawing of fig. 18, the spliced side plates 1 are used for splicing a turnover box, the spliced side plates 1 are connected in an incomplete clamping mode with gaps by mortise and tenon, and are connected and combined with the mortise and tenon in a full clamping mode with seamless and no gaps by mortise and tenon, one mortise and tenon is used for connecting in two modes, namely a long clamping mode and a short clamping mode, a plurality of spliced side plates 1 can be connected into a length of 2a + 2b +3c, which is just the same plane connection length of two upper cover plates and lower cover plates 3, so that the spliced side plates 1 and the upper cover plates and the lower cover plates 3 can be expanded into a large-inner-space turnover box by using two modes, namely the long connecting mode and the short connecting mode.

The invention can expand the turnover box and has three principles:

the first invention relates to a long and short dual-purpose tenon and a deep and shallow dual-purpose mortise: the mortise and tenon structure of the splicing side plate 1 can be connected into 2 types of length and length, two concave racks 26 with equal depth are arranged in the deep and shallow dual-purpose mortise and tenon groove 10 of the splicing side plate 1, so that the deep and shallow dual-purpose mortise and tenon groove 10 can be a deep and shallow dual-purpose mortise and tenon groove which can use one concave rack 26 and can clamp mortise and tenon heads by using 2 concave racks 26. The single-sliding long-short dual-purpose tenon side 4 of the splicing side plate 1 is provided with two convex racks 25 which are used for equally dividing the section length of the tenon, so that the single-sliding long-short dual-purpose tenon side 4 becomes a long and short dual-purpose tenon capable of using one

convex rack

25 and 2 convex racks 25 to clamp the mortise slot.

Secondly, the invention discloses the matching of the sizes of the mortise and tenon joints of the splicing side plate 1, namely the relation of the space width of each convex tooth: in the same single-slip long-short dual-purpose tenon side 4, the width of a convex rack 25 of 1 single-slip long-short dual-purpose tenon side 4 is equal to the width of another convex rack 25 of 1 single-slip long-short dual-purpose tenon side 4 is equal to the width of the same side surface deep-shallow dual-purpose mortise slot 10, and the width of a concave rack 26 of 1 side surface deep-shallow dual-purpose mortise slot 10 is equal to the width of another concave rack 26 of 1 side surface deep-shallow dual-purpose mortise slot 10 and the width of a concave rack 26 of 1 end surface shallow mortise slot 11 is equal to 1: 1. The size of the mortise is matched, so that 1 convex rack 25 of the single-sliding long and short dual-purpose mortise side 4 is clamped on 1 concave rack 26 of the side deep and shallow dual-purpose mortise groove 10 to generate short-size connection; and 2 convex racks 25 of the long and short dual-purpose tenon sides 4 can be clamped on 2 concave racks 26 of the side deep and shallow dual-purpose mortise groove 10 to form long-size connection. The mortise and tenon joint of the spliced side plates 1 can be produced into two connection sizes of long and short, and the problem that a traditional mortise and tenon connection mode only has one connection size and cannot be spliced into a unit turnover box by one side plate and can be spliced into a plurality of units to be combined into the turnover box is solved.

Thirdly, the position of each mortise and tenon of the splicing side plate 1 is set as follows: the single-sliding long and short dual-purpose tenon edge 4 and the single-sliding double-mortise slot edge 5 are arranged on two opposite sides of the splicing side plate 1. The single-sliding long-short dual-purpose tenon strip 4 is an end face on one side, can be used for corner connection and long-time delay extension, and is a corner and extension dual-purpose tenon strip; the deep and shallow dual-purpose mortise slot 10 of the single-sliding double-mortise slot edge 5 is arranged on the inner surface 9 of the spliced plate of the spliced side plate 1 and is only used for corner turning, and the shallow mortise slot 11 of the single-sliding double-mortise slot edge 5 is arranged on the end surface of the spliced side plate 1 and is only used for extending the delay length; the mortise slot of the splicing side plate 1 is divided into a deep and shallow dual-purpose mortise slot 10 for corners and a shallow mortise slot 11 for expansion.

Fourthly, the invention discloses an extended volume connection mode of the structure splicing side plate 1: as shown in fig. 12, when the turnover box of one unit is spliced, one spliced side plate 1 is connected with the deep and shallow mortise slot 10 of the other spliced side plate 1 in a seamless corner mode only by using the single-sliding long and short dual-purpose tenon side 4. As shown in fig. 13, when the circulation box is expanded, the single-sliding long and short mortise 4 of the first spliced side plate 1 and the deep and shallow mortise 10 of the second spliced side plate 1 are connected in a c/2 gap corner manner, and the shallow mortise 11 of the third spliced side plate 1 is connected with one convex rack 25 in the single-sliding long and short mortise 4 of the first spliced side plate 1. The description that the specific polylith concatenation curb plate 1 can expand to connect into and has already expanded upper and lower apron 3 matched with is as follows:

as shown in fig. 13, when the circulation box is expanded, only one convex rack 25 of the single-slip long and short dual-purpose tenon side 4 of the side plate 1[ shown in the grid lines ] is clamped into 1 concave rack 26 of the deep and shallow dual-purpose mortise slot 10 at the corner position, and c/2 depth is left in the deep and shallow dual-purpose mortise slot 10, compared with the full clamping in fig. 12, the length of the spliced side plate 1 corresponding to the corner position [ shown in the grid lines ] is increased by c/2; the extension splicing side plate 1[ shown without grid lines ] has only one convex rack 25 on the single-sliding long and short dual-purpose tenon side 4 clamped into one concave rack 26 of the shallow mortise slot 11, and the extension splicing side plate 1[ shown without grid lines ] has the other convex rack 25 on the single-sliding long and short dual-purpose tenon side 4 not in the mortise slot, so that compared with the case of full clamping in the picture 12, the extension splicing side plate 1[ shown without grid lines ] has the length increased by c/2. Thus, as shown in fig. 13, in the extended connection mode, the length of the extended spliced side plate 1[ without grid lines ] at the corner position [ indicated by grid lines ] is increased by c/2, the length of the extended spliced side plate 1[ without grid lines ] is increased by c/2, compared with the full-clamping of fig. 12, the total length of c is increased by the corner of the same plane and the extended 2 spliced side plates 1, which is equivalent to the thickness of the spliced side plate 1, i.e. two units corresponding to fig. 12, are spliced, with two splicing side plates 1 in the middle, so that, the splicing side plate 1 of figure 13 can be equal to the total length of the two upper and lower cover plates 3, the total length of the square formed by connecting 8

splicing side plates

1 and 4 upper and lower cover plates 3 for the extension of figure 13 is completely equal, and the square formed by connecting 8 splicing side plates 1 in an extension mode and the square formed by connecting 4 upper cover plates and 4 lower cover plates 3 in an extension mode are connected to form a turnover box.

As shown in fig. 13, when the container is expanded,

the total length a of one upper cover plate 3 and the total length of one lower cover plate 3 are [ b + c + c/2] (corner position [ indicated by grid lines ] to splice the total length of the side plates 1;

the total length a of one upper cover plate 3 and one lower cover plate 3 is [ b + c + c/2] is the total length of the extended [ non-grid line representation ] splicing side plates 1;

the total length 2a of one side of 4 upper and lower cover plates 3 of 2x2 is 2x [ b + c + c/2] ═ 2b +3c (corner position [ indicated by the grid lines ] total length of the splice side plate 1 + total length of the extension [ indicated by the grid lines ] total length of the splice side plate 1. The splicing of the expanded turnover box with the size of 4 upper cover plates and 4 lower cover plates 3 of 2x2 can be realized by only using the two plates of the upper cover plate and the lower cover plate 3 and the splicing side plate 1.

According to the unit circulation box splicing method, as shown in fig. 12, when 4 spliced

side plates

1 and 2 upper and lower cover plates 3 are spliced into a unit circulation box, the single-sliding long and short dual-purpose mortise side 4 on the end face of one spliced side plate 1 is completely clamped into the side surface deep and shallow dual-purpose mortise slot 10 on the side surface of the other spliced side plate 1, and no hole space exists in the side surface deep and shallow dual-purpose mortise slot 10, namely, two convex racks 25 of the single-sliding long and short dual-purpose mortise side 4 and two concave racks 26 of the side surface deep and shallow dual-purpose mortise slot 10 are completely embedded without hole spaces.

The length a of the upper cover plate and the lower cover plate 3 of the unit turnover box is equal to the main body length b of the splicing side plate 1, the width c of the single-sliding long-short dual-purpose tenon side 4 of the splicing side plate 1 and the depth c/2 of the shallow mortise groove 11 of the splicing side plate 1, namely, a is equal to b + c + c/2.

The two corner splicing methods of the two spliced side plates 1 are as follows: as shown in fig. 12, in the corner splicing method of the first unit turnover box, two convex racks 25 of the single-sliding long and short dual-purpose tenon side 4 of the first spliced side plate 1 are all clamped in the deep and shallow dual-purpose mortise slot 10 of the second spliced side plate 1, and no hole is left in the deep and shallow dual-purpose mortise slot 10. As shown in fig. 13, in the second corner splicing method for the expanded circulation box, the first spliced side plate 1 is used for single-sliding two convex racks 25 of the long and short dual-purpose tenon sides 4, only one convex rack 25 outside and one concave rack 26 outside the side deep and shallow dual-purpose mortise slot 10 of the second spliced side plate 1 are fully embedded to realize corner splicing, a hole space is arranged in the side deep and shallow dual-purpose mortise slot 10 at the corner, the depth of the hole space is c/2, and the length of the hole space is equivalent to that the length of the c/2 is increased in the spliced structure of the first spliced side plate 1. The coplanar extension splicing method comprises the following steps:

the same-plane prolonged splicing method of the two spliced side plates 1 comprises the following steps: when the first spliced side plate 1 with the length of c/2 is extended in the same plane, the shallow mortise slot 11 on the end surface of the first spliced side plate 1 with the length of c/2 is only c/2 deep, and then the single-sliding long-short dual-purpose tenon side 4 of the third spliced side plate 1 for extension in the same plane can be clamped in the shallow mortise slot 11 of the first spliced side plate 1 only by the outer convex rack 25 of the two convex racks 25.

The spliced airbag system 23 is another invention point of the patent, and the key invention of the spliced airbag system 23 has three points:

the first point is that the combined air bags 2 of the single plates are spliced into a spliced air bag system 23 of the turnover box, and the spliced air bag system 23 of the turnover box is formed by splicing the combined air bags with the spliced side plates 1 and the upper cover plate and the lower cover plate 3 which are respectively independent.

The air pressure of all air pipes 12 of the whole cargo turnover box is equal: all air pipes 12 in each plate of the whole cargo turnover box are positioned and clamped by using the clamping type connecting structures of the splicing side plate 1 and the upper cover plate and the lower cover plate 3, or the clamping type connecting structures of the splicing side plate 1 and the splicing side plate 1 are positioned and clamped, or the clamping type connecting structures of the upper cover plate 3, the lower cover plate 3 and the upper cover plate 3 are positioned and clamped, so that the air two-way valves 16 of the two plates are communicated with the air pipes 12 of the two plates. All the air pipes 12 in all the plates of the whole cargo turnover box are communicated, so that the air pressures of all the air pipes 12 of the whole cargo turnover box are equal.

The structure of the single-plate combined air bag 2 can also be described as follows: an air pipe 12, an air inlet 15, an air guide port 14 and an air outlet 13 of the air pipe 12 are respectively arranged in the bodies of the spliced side plate 1 and the upper cover plate 3, the air inlet 15 is provided with an air inlet one-way valve, the air guide port 14 is provided with an air two-way valve 16, one end of the air two-way valve 16 is communicated with the air guide port 14 of the spliced side plate 1 or the upper cover plate 3 in the plate, the other end of the air two-way valve 16 is opened on the surface of the spliced side plate 1 or the upper cover plate 3, so that the air two-way valve 16 is communicated with the air two-way valves 16 of other plates, and an air bag 24 adhered to the inner surface 9 of the spliced plate communicated with the air outlet 13 or the inner surfaces of.

The turnover box has an airtight structure: the two connected plates communicate with each other through the gas two-way valve 16 on the gas guide port 14, the gas two-way valves 16 of the two plates are designed to be corresponding in position, but when the circulation box is assembled, the gas two-way valves 16 of the two plates are enabled to be corresponding in position, the two gas two-way valves 16 of the two plates are clamped and fixed in position by means of the clamping type connecting structure arranged on the two sides of the gas two-way valves 16 of the two plates, the two gas two-way valves 16 of the two plates are fixed to be corresponding in position, and then gas is filled into the circulation box without. The spherical segment body of the spherical segment-shaped sliding tenon bulge 17, the clamping and sliding short mortise slot 18 which is tightly matched with the spherical segment body, and the positioning recess 21 at the bottom of the clamping and sliding short mortise slot 18 are important structural guarantees for positioning the two gas two-way valves 16 of the two plates in a gas-tight state. In industrial product design, the optimal distance between the two-piece gas bi-directional valve 16 and the snap-in type connection structure parts on both sides is an important parameter for achieving gas-tightness.

The single-plate combined air bag 2 can be used for air leakage detection: when the spliced side plate 1 or the upper and lower cover plates 3 are not connected with other plates, gas is filled from the gas inlet 15, the sliding gas valve elliptical ball 33 of the gas two-way valve 16 seals the small hole end 32, the gas can only enter the space between the spliced side plate 1 or the upper and lower cover plates 3 and the air bag film 24, the air bag film 24 is expanded, if the air bag film 24 cannot be expanded, the gas two-way valve 16 or the air bag film 24 can be detected to leak gas, or other reasons exist. The single-plate combined air bag 2 is very convenient for air leakage detection. The gas bi-directional valve 16 and the inlet check valve of the inlet port 15 are essential components for gas leakage detection.

The part of the inside of the turnover box is not provided with the film expansion air bag: the spliced air bag system 23 of the turnover box is formed by communicating the gas two-way valves 16 of the combined air bags 2 of the spliced side plates 1 and the upper and lower cover plates 3 which form the turnover box, and in addition, parts are added to block the gas two-way valves 16 of a certain block or a plurality of blocks, so that the air bag films 24 of a certain block or a plurality of blocks can not be expanded into air bags to meet the special requirements of goods filled in the turnover box.

Equal advantages of gas pressure: all the air pipes 12 in all the plates of the whole goods turnover box are communicated, so that the whole goods turnover box can only have one air inlet 15, or each plate can have the air inlet 15, but when the goods turnover box is inflated, only one air inlet 15 can be inflated to ensure that the air bag films 24 in all the goods turnover box are inflated by air to be expanded, shockproof fillers used in the existing turnover box are replaced, and the operation of inflating only one air inlet 15 is simplified. All the air pipes 12 are communicated, so that all the air bag films 24 in the goods turnover box have the characteristic of the same air pressure, the goods can be kept in the middle position in the turnover box, and the goods in the turnover box can be protected more favorably.

The second point is that one turnover box can only have one spliced air bag system 23, or can have a plurality of spliced air bag systems 23, and the air pressure of all air bag films 24 in one spliced air bag system 23 is equal. Closing one or more or each gas two-way valve 16 of the spliced side plate 1 of the turnover box; or, the gas two-way valve 16 of one or more or each upper and lower cover plates 3 of the turnover box is closed; a container may have a plurality of spliced airbag systems 23, such as by closing the gas bi-directional valve 16 of each panel, and the combined airbag 2 of each panel becomes a spliced airbag system 23. Multiple bladder membranes 24 in a turnaround box may present different inflated bladder sizes to accommodate different contents of the turnaround box.

The third point is that the gas two-way valve 16 has three functions: acting on a first air pipe 12 for communicating different plates; secondly, when the combined air bag 2 of the single plate is used for detecting air leakage, the combined air bag is used for plugging the communicating ports of the air pipes 12 of the two plates, namely the air guide ports 14; and thirdly, when the circulation boxes with different sizes are spliced, if the air guide port 14 of one plate is not communicated with the air guide ports 14 of any plates, the air guide port 14 of the plate is exposed to the outside, other air guide ports 14 of the plate are communicated with the air guide ports 14 of other plates, the air bag film 24 of the plate needs to be capable of expanding into an air bag, and the air two-way valve 16 exposed to the outside air guide port 14 can seal the air flow, so that the air bag film 24 of the plate can be ensured to be capable of expanding into the air bag.
