Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard boxes, and in particular to a high-strength corrugated cardboard box. Background Technology

[0002] Corrugated cardboard boxes, due to their excellent cushioning performance, lightweight, and cost-effectiveness, have been widely used in the express delivery and logistics industry, becoming a mainstay of transport packaging. With the surge in express delivery volume and the increasing demand for transporting high-value, precision instruments, and other fragile items, higher requirements are being placed on the overall compressive strength of corrugated cardboard boxes. However, when subjected to high-intensity stacking and compression, the existing corrugated cardboard box structure still has limitations in its overall load-bearing capacity, making the boxes prone to dents, deformation, and even collapse. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect of insufficient load-bearing capacity of corrugated cardboard boxes in the prior art, thereby providing a high-strength corrugated cardboard box.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-strength corrugated cardboard box, comprising:

[0006] The enclosure includes a bottom plate, four side plates, a vertical load-bearing plate, and a horizontal load-bearing plate. The side plates are all fixed to the bottom plate. The vertical load-bearing plate and the horizontal load-bearing plate are located inside the side plates. The vertical load-bearing plate is fixed to the bottom plate, and the horizontal load-bearing plate is fixed to two adjacent vertical load-bearing plates.

[0007] The cover includes a top plate assembly and four cover side plates, all of which are fixed to the top plate assembly. The top plate assembly includes a first top plate, a pressure plate, and a second top plate arranged vertically. The projection of the vertical pressure plate at least partially overlaps with the projection of the pressure plate.

[0008] Preferably, the vertical load-bearing plate extends in the vertical direction and abuts against the top plate assembly; the horizontal load-bearing plate extends in the horizontal direction and its two ends are respectively fixed to the two vertical load-bearing plates; when the box and the cover are closed, the vertical load-bearing plate abuts against the top plate assembly, and the box and the cover jointly bear the pressure in the vertical direction.

[0009] Preferably, the side of the base plate is provided with a connecting groove, and the vertical load-bearing plate protrudes with a connecting part, which extends into the connecting groove and is snapped and fixed with the base plate; the snap-fit ​​fixing of the base plate and the side plate means that either one can be replaced if it is severely damaged.

[0010] Preferably, the vertical load-bearing plate is L-shaped and is located at the four corners of the box body; this facilitates connection with the horizontal load-bearing plate on the side closest to it, and connection with the bottom plate on the two sides closest to it, while reducing the amount of material used for the load-bearing plate along the vertical direction.

[0011] Preferably, there is one pressure plate, and the pressure plate abuts against both the first top plate and the second top plate; by adding a pressure plate on the basis of the original corrugated cardboard load-bearing capacity, the load-bearing capacity of the cover is improved.

[0012] Preferably, there are multiple pressure plates, some of which are spaced apart along the length direction and others are spaced apart along the width direction, and the pressure plates are snapped together; when the box is closed, the box not only has to bear the pressure from other boxes, but also has to bear the pressure of the cover itself, thus giving the box a greater pressure-bearing capacity.

[0013] Preferably, the pressure plates arranged at intervals along the length direction are provided with snap-fit ​​grooves, and the pressure plates arranged along the width direction are provided with snap-fit ​​blocks, which are snapped into the snap-fit ​​grooves; the detachable design allows for a certain degree of recycling even if some parts are damaged during use.

[0014] Preferably, the cover is provided with a groove, the opening of the groove faces the box body, and the cross-sectional area of ​​the box body is smaller than the area of ​​the groove in the horizontal direction; to ensure that the groove of the cover can contact the side of the box body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The high-strength corrugated cardboard box provided in the above technical solution includes a box body and a lid. The box body includes a bottom plate and four side plates, which are fixed to the bottom plate, forming the basic shape of the box. In addition, the box body is provided with vertical and horizontal load-bearing plates inside.

[0028] Please refer to the following carefully. Figures 1 to 5 This utility model embodiment provides a high-strength corrugated cardboard box, including: box body 1 and lid 2. Specifically, the box body 1 includes a bottom plate 11 and four side plates 12. The four side plates 12 can be selected according to the weight of the loaded objects, and can be any type of cardboard, such as single-wall corrugated cardboard, double-wall corrugated cardboard, triple-wall corrugated cardboard, or extra-strong double-wall corrugated cardboard. The four side plates 12 are fixedly connected to the bottom plate 11, forming the frame of the box body 1. The box body 1 also includes vertical load-bearing plates 13 and horizontal load-bearing plates 14. Both vertical load-bearing plates 13 and horizontal load-bearing plates 14 are set inside the box body 1. The vertical load-bearing plates 13 are L-shaped, and there can be four vertical load-bearing plates 13, specifically set at the four corners of the box body 1. Along the vertical direction, the projection of the vertical load-bearing plates 13 at least partially overlaps with the four right angles of the box body 1. During the stacking of the boxes body 1, the force borne by the box body 1 is mainly the force along the vertical direction. The vertical support plates can bear most of the force along the vertical direction, thereby improving the load-bearing capacity of the box body 1 along the vertical direction.

[0029] The cover 2 includes a top plate assembly 21 and four cover side plates 22. The four cover side plates 22 are of the same model as the four box side plates 12. All four cover side plates 22 are fixedly connected to the top plate assembly 21, forming the basic frame of the cover 2. In the vertical direction, the top plate assembly 21 includes a first top plate 211, a pressure plate 212, and a second top plate 213. The pressure plate 212 is located between the first top plate 211 and the second top plate 213. The components can be fixed together by adhesive. The presence of the pressure plate 212 allows the cover 2 to withstand a large load. Similarly, along the vertical direction, the projection of the vertical load-bearing plate 13 overlaps at least partially with the projection of the pressure plate 212. When the box 1 closes the cover 2, the vertical load-bearing plate 13 abuts against the top plate assembly 21. The pressure plate 212 and the vertical load-bearing plate 13 can jointly bear most of the force along the vertical direction, thus increasing the load-bearing capacity along the vertical direction and enhancing the overall load-bearing capacity of the box 1.

[0030] It is conceivable that the pressure plate 212 can also be configured as multiple vertical load-bearing plates and multiple horizontal load-bearing plates. The multiple vertical load-bearing plates are spaced apart along the length direction, and the multiple horizontal load-bearing plates can be spaced apart along the width direction. When the box 1 is closed with the cover 2, the box 1 still needs to bear the total weight from the cover 2, reducing the material used for the load-bearing plates without affecting the load-bearing capacity of the cover 2, so that the box 1 can withstand more pressure. In addition, within the four side panels of the box 1, two horizontal load-bearing plates 14 can be set between the two vertical load-bearing plates 13. In the vertical direction, the two horizontal load-bearing plates 14 are located on the upper and lower sides of the side panels of the box 1, respectively, and the horizontal load-bearing plates 14 are fixedly connected to the vertical load-bearing plates 13. The lower horizontal load-bearing plate 14 serves to reinforce the side panel of the box 1, and the upper horizontal load-bearing plate 14 shares part of the horizontal reverse pressure of the box 1, preventing the side of the box 1 from collapsing when the stacking is uneven.

[0031] It is conceivable that the bottom plate 11 is provided with a connecting groove 15 on the side of the box body 1, and the vertical load-bearing plate 13 inside the side of the box body 1 is provided with a protruding connecting part 16 on the side of the bottom plate 11. The connecting part 16 can be inserted into the connecting groove 15 and locked with the bottom plate 11. If either the bottom plate 11 or the side of the box body 1 is seriously damaged, it can be replaced, which saves materials to a certain extent.

[0032] It is conceivable that the vertical bearing plate 212 is L-shaped, which facilitates the connection between the side close to the horizontal bearing plate 14 and the side close to the bottom plate 11 and the bottom plate 11, and reduces the material used for the bearing plate in the vertical direction.

[0033] It is conceivable that the cover 2 is provided with a groove 23, the opening of the groove 23 facing the box 1. In the horizontal direction, the cross-sectional area of ​​the box 1 is smaller than the area of ​​the groove 23, that is, the groove 23 of the cover 2 can contact the four sides of the box 1 respectively, ensuring that the cover 2 can form a sealed space with the box 1.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
