Technical Field

[0001] The utility model relates to the field of blanking and folding boxes, in particular to a hollow board plug-in box. Background Technique

[0002] With the rapid development of the express delivery industry in the Internet era, the consumption of express packaging continues to grow. Various logistics boxes are widely used in the field of logistics transportation. Logistics boxes are usually sealed with tape. Since the tape itself is a material that is difficult to degrade, the use of a large amount of tape will cause a series of environmental protection problems. When the tape on the existing packaging logistics box is firmly adhered, tools are needed to disassemble it, and the effect of rapid use cannot be achieved.

[0003] In order to solve the above problems, a quick-disassembly type of logistics box has appeared on the market. The box body is usually formed by folding corrugated cardboard, and the mutual connection between the cover plates of the box body is realized through the buckle structure formed by blanking on the corrugated cardboard. However, the buckle structure of the corrugated paper is easily damaged and the connection strength is relatively low, which is not conducive to the environmental protection recycling of the box body. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hollow board plug-in box, which has the advantages of high structural strength and high connection position strength.

The left side plate, the rear side plate, the right side plate and the front side plate are all made of hollow board. Cover plates are arranged on both sides of the left side plate and the right side plate in the height direction. Plug-in covers are arranged on both sides of the front side plate and the rear side plate in the height direction. Insertion structures are arranged at the outward corner positions of the plug-in covers. Accommodating structures matched with the insertion structures are arranged on the cover plates. The insertion structure includes an insertion end, a first clamping groove and a second clamping groove. The first clamping groove is arranged on the side surface of the plug-in cover and recesses inward along the length direction of the plug-in cover. The second clamping groove is arranged on the top of the plug-in cover and recesses inward along the thickness direction of the plug-in cover. The insertion end is formed at the corner position of the plug-in cover and is located between the first clamping groove and the second clamping groove. The accommodating structure includes an accommodating hole, an insertion groove and a deformation hole. The accommodating hole is arranged inside the cover plate. The deformation holes are respectively arranged at the connection positions between the cover plate and the left side plate and between the cover plate and the right side plate. The accommodating hole penetrates through the middle of the cover plate and is matched with the second clamping groove. The insertion groove penetrates through the thickness direction of the cover plate. The two ends of the insertion groove in the length direction are respectively connected to the accommodating hole and the deformation hole. The insertion groove and the deformation hole are for the insertion end to be inserted into the inner side of the cover plate.

[0006] Preferably, the plug cover is divided into an insertion area and a connection area in the width direction, a bending groove is arranged between the insertion area and the connection area, the bending groove extends along the length direction of the plug cover, and the insertion end, the first clamping groove and the second clamping groove are respectively arranged on both sides of the insertion area in the length direction.

[0010] Preferably, an arc-shaped block is arranged between adjacent insertion ends along the length direction of the plug cover, both ends of the arc-shaped block in the length direction are recessed inward, and the second clamping groove is located between the insertion end and the arc-shaped block.

[0011] By adopting the above technical solution, it is convenient for the insertion ends at both ends of the plug cover to deform towards the center, which is convenient for the rigid plug cover to be inserted into the cover plate, and at the same time, it is convenient for the second clamping groove to be clamped with the large arc section.

[0012] Preferably, an inner groove is arranged at the top of the arc-shaped block.

[0013] By adopting the above technical solution, it is convenient for the operator to apply force to the plug cover and convenient for the plug cover to disengage from the cover plate.

[0020] Preferably, the receiving structures on each cover plate are mirror-symmetrical about the center of the cover plate, and the insertion structures on each inserted cover are mirror-symmetrical about the center of the inserted cover.

[0021] By adopting the above technical solution, it plays a role of four-point positioning connection at the top and bottom of the box body.

The bottom and top of the box body are connected through the receiving structure and the insertion structure between the cover plate and the inserted cover. During the connection process, the deformation hole prevents tearing at the connection position between the side plate and the cover plate. The front end of the insertion end is located at the front bottom of the receiving hole of the cover plate, and the cover plate plays a clamping role on the insertion end, thereby obtaining higher structural strength at the connection position.

[0032] Embodiment 1:

[0033] As Figures 1 to 3 shown, a hollow board insertion cover box successively includes a left side plate 11, a rear side plate 12, a right side plate 13, and a front side plate 14. The left side plate 11, the rear side plate 12, the right side plate 13, and the front side plate 14 are all made of hollow boards. The hollow board in this application is a plastic hollow board. More specifically, the hollow board can adopt a structure with uniformly distributed linear channels inside, while in this application, an S-shaped hollow board with a large curvature is used. The S-shaped hollow board includes S-shaped hollow channels uniformly distributed along the length direction, and the S-shaped hollow channels extend along the height direction of the board body. Figure 1 It can also be understood as a die-cutting drawing, that is, the left side plate 11, the rear side plate 12, the right side plate 13, and the front side plate 14 are formed by cutting a whole board, and pre-pressing is required at the bending positions for convenient folding.

[0034] As Figure 1 shown, cover plates 2 are arranged on both sides in the height direction of the left side plate 11 and the right side plate 13. The cover plates 2 are integral with the left side plate 11 and the right side plate 13, and at the same time, bending marks are provided at the bending positions. Insertion covers 3 are arranged on both sides in the height direction of the front side plate 14 and the rear side plate 12. Insertion structures are arranged at the outward corner positions of the insertion covers 3. A receiving structure matching the insertion structure is arranged on the cover plates 2. At the same time, it should be understood that after the cover plates 2 are folded inward, the insertion covers 3 are used to fix one end of the two cover plates 2. Therefore, the receiving structures on each cover plate 2 are mirror-symmetrical with the center of the cover plate 2 as the center, and the insertion structures on each insertion cover 3 are mirror-symmetrical with the center of the insertion cover 3 as the center, facilitating the fixation of both sides of the cover plates 2 at the top and bottom.

[0035] The specific insertion structure includes an insertion end 31, a first clamping groove 32 and a second clamping groove 33. The first clamping groove 32 is arranged on the side surface of the plug cover 3 and is recessed inward along the length direction of the plug cover 3. The second clamping groove 33 is arranged on the top of the plug cover 3 and is recessed inward along the thickness direction of the plug cover 3. The insertion end 31 is formed at the angular position of the plug cover 3 and is located between the first clamping groove 32 and the second clamping groove 33. The cross-sectional shape of the first clamping groove 32 is rectangular, and the first clamping groove 32 penetrates outward along the length direction of the plug cover 3. The connection position between the first clamping groove 32 and the side surface of the plug cover 3 is in an arc transition. The connection position between the first clamping groove 32 and the insertion end 31 is in an arc transition. The side surface of the insertion end 31 is lower than the side surface of the plug cover 3. In the unfolded state, the top of the insertion end 31 is flush with the top of the cover plate 2.

[0036] The specific accommodation structure includes an accommodation hole 21, an insertion groove 22 and a deformation hole 23. The accommodation hole 21 is arranged in the cover plate 2. The deformation holes 23 are respectively arranged at the connection positions between the cover plate 2 and the left side plate 11 and between the cover plate 2 and the right side plate 13. The accommodation hole 21 penetrates through the middle of the cover plate 2 and cooperates with the second clamping groove 33. The insertion groove 22 penetrates through the thickness direction of the cover plate 2. The two ends in the length direction of the insertion groove 22 are respectively connected to the accommodation hole 21 and the deformation hole 23. The insertion groove 22 and the deformation hole 23 are for the insertion end 31 to be inserted into the inner side of the cover plate 2. Among them, the accommodation hole 21 successively includes a first inclined section 211, a large arc section 212, a horizontal section 213, a small arc section 214 and a second inclined section 215 that are connected end to end. The starting end of the first inclined section 211 is connected to the ending end of the second inclined section 215. The insertion groove 22 includes a third inclined section 221 and a vertical section 222. The starting end of the third inclined section 221 is communicated with the starting end of the first inclined section 211. The ending end of the third inclined section 221 is communicated with the starting end of the vertical section 222. The ending end of the vertical section 222 is communicated with the deformation hole 23. The deformation hole 23 extends along the bending direction of the cover plate 2.

[0037] As Figure 2 and Figure 3 shown, in order to facilitate the insertion of the insertion end 31 into the accommodation hole 21, the plug cover 3 needs to be bent. Therefore, the plug cover 3 is divided into an insertion area 41 and a connection area 42 in the width direction. A bending groove 43 is arranged between the insertion area 41 and the connection area 42. The bending groove 43 extends along the length direction of the plug cover 3. The insertion end 31, the first clamping groove 32 and the second clamping groove 33 are respectively arranged on both sides in the length direction of the insertion area 41.

[0038] At the same time, as Figure 2As shown in the figure, in order to better limit the second card slot 33 and the large arc segment 212 in the height direction, an arc-shaped block 44 is provided between adjacent insertion ends 31 of the insertion cover 3 along the length direction. Both ends of the arc-shaped block 44 in the length direction are recessed inward, and the second card slot 33 is located between the insertion end 31 and the arc-shaped block 44.

[0039] Working principle:

[0040] The left side plate 11 and the front side plate 14 of the box body are seamlessly connected by hot melt welding. At the same time, the cover plates 2 on both sides of the top and bottom are folded inward. Subsequently, the insertion cover 3 is deformed under pressure at the bending groove 43, and the insertion end 31 enters the receiving hole 21 along the insertion groove 22. At the same time, the deformation hole 23 prevents the connection position between the cover plate 2 and the side plate from being torn, providing a larger deformation space. After being fixed, the receiving hole 21 clamps the insertion end 31, and when combined with the plastic hollow plate, it has stronger structural strength and clamping effect, which is convenient for recycling and reuse.

[0041] Embodiment 2:

[0042] As Figure 4 shown, another hollow plate insertion cover box is improved in the structure of the arc-shaped block 44 and the insertion end 31. An inner groove 45 is provided at the top of the arc-shaped block, and the inner groove 45 is for the operator's finger to buckle, which is convenient for opening the insertion cover 3; at the same time, a guiding chamfer 46 is provided at the outer end of the insertion end 31.
