[0001] This utility model relates to the field of corrugated cardboard box technology, specifically a corrugated cardboard box with high compression resistance. Background Technology

[0002] Corrugated cardboard boxes are a very common type of packaging container, widely used in logistics, warehousing, and commodity transportation. The linerboard is the outer layer of the corrugated cardboard, mainly serving a protective and aesthetic purpose. The linerboard usually has good printability and can be printed with various patterns and text information. The core paper is the core of the corrugated cardboard, which is formed into a wavy corrugation after being pressed and molded. The shape and size of the corrugations have a significant impact on the performance of the corrugated cardboard. The linerboard is the inner layer of the corrugated cardboard, mainly serving to support and protect the corrugated core paper. The strength and toughness of the linerboard also affect the overall performance of the corrugated cardboard. Finally, adhesives are used to bond the linerboard, corrugated core paper, and linerboard together.

[0003] Currently, corrugated cardboard boxes are made with multi-layer composite structures to increase their compression resistance. However, during transportation, corrugated cardboard boxes are stacked to increase space utilization. But corrugated cardboard boxes need to withstand the pressure from the goods above them. On bumpy roads, the top of the corrugated cardboard boxes located on the lower layer of the transport vehicle is easily squeezed and deformed, causing damage to the goods.

[0004] Therefore, a corrugated cardboard box with high compression resistance was proposed to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-5 This embodiment provides a corrugated cardboard box with high compression resistance, including a box body 1. Aluminum alloy support rods 12 with vertical support are installed at the four corners inside the box body 1. A cover plate 2 is installed on the top of the box body 1. A cross frame 21 to improve the compression resistance of the cover plate 2 is installed on the inner top of the cover plate 2. The four corners at the bottom of the cross frame 21 are supported by the tops of the four aluminum alloy support rods 12. The cross frame 21 can improve the compression resistance of the top of the cover plate 2, reducing the risk of deformation caused by the pressure from above. At the same time, the pressure on the top of the cover plate 2 is transmitted to the cross frame 21, and the pressure at the four corners at the bottom of the cross frame 21 is transmitted to the aluminum alloy support rods 12, so that most of the pressure of the corrugated cardboard boxes stacked above is concentrated on the aluminum alloy support rods 12, thereby effectively improving the compression resistance of the corrugated cardboard box.

[0028] In this embodiment, as Figure 2 As shown, a plastic baffle is installed at each of the four inner corners of the box 1 to form a triangular groove 11. The inner dimensions of the triangular groove 11 match the dimensions of the aluminum alloy support rod 12. The aluminum alloy support rod 12 is fixedly installed inside the triangular groove 11, and the top and bottom of the aluminum alloy support rod 12 are flush with the top and bottom of the triangular groove 11. By installing the aluminum alloy support rod 12 at the four inner corners of the box 1, the edges and corners of the overall box 1 are more stable and less prone to deformation, while providing four support points with high pressure resistance.

[0029] In this embodiment, as Figure 1 and Figure 3 As shown, support pads 22 are installed at all four ends of the cross frame 21. The support pads 22 are made of solid wood. When the cover plate 2 is placed on top of the box body 1, the bottom of the four support pads 22 on the cross frame 21 is respectively attached to the top of the four aluminum alloy support rods 12. When the corrugated boxes are stacked, the bottom corner of the upper corrugated box will put pressure on the support pads 22 on the cover plate 2 of the lower corrugated box. At this time, the support pads 22 transmit the pressure to the aluminum alloy support rods 12. The aluminum alloy support rods 12 provide stable support for the stacked corrugated boxes, thereby effectively improving the pressure resistance of the corrugated boxes during stacking and transportation.

[0030] In this embodiment, as Figure 3 As shown, each of the four cross plates on the cross frame 21 is equipped with a rubber pad 23 at its bottom. When the cover plate 2 is placed on top of the box 1, the bottom of the rubber pad 23 is attached to the top of the transported goods. The top of the cross frame 21 is fixedly attached to the top of the inner side of the cover plate 2. Since the cross frame 21 is attached to the top of the inner side of the cover plate 2, it can provide the cover plate 2 with a certain compressive strength, reducing the risk of deformation of the cover plate 2 after being compressed. At the same time, when the cover plate 2 deforms downward, the rubber pad 23 is squeezed against the goods, which can play a certain shock-absorbing and buffering effect on the surface of the goods, reducing the risk of deformation of the goods.

[0031] In this embodiment, as Figure 4 and Figure 5 As shown, a base plate 3 is installed at the bottom of the box 1, and a connecting seat 31 matching the size of the connecting groove 13 is installed on the top of the base plate 3. The inner top of the connecting seat 31 is made of corrugated paper to form a grid with vertical pressure resistance. Protective foot pads are installed at the four corners of the connecting seat 31. The top of the protective foot pads fits against the bottom of the aluminum alloy support rod 12. The corrugated paper grid on the top of the connecting seat 31 can provide good support for the bottom of the box 1, improve the load-bearing capacity of the box 1, and is not easy to deform. At the same time, the protective foot pads can prevent the aluminum alloy support rod 12 from piercing the bottom of the box 1 after being compressed.

[0032] Working Principle: This highly pressure-resistant corrugated cardboard box utilizes aluminum alloy support rods 12 installed at the four inner corners of the box body 1. This makes the corners of the box body 1 more stable and less prone to deformation, while also providing four support points with high pressure resistance. When the corrugated cardboard boxes are stacked, the bottom corner of the upper corrugated cardboard box applies pressure to the support pad 22 on the lower corrugated cardboard box cover 2. The support pad 22 then transfers the pressure to the aluminum alloy support rods 12, providing stable support for the stacked corrugated cardboard boxes. This effectively improves the pressure resistance of the corrugated cardboard boxes during stacking and transportation. Simultaneously, the cross frame 21, attached to the top inner side of the cover 2, provides a certain degree of pressure resistance to the cover 2, reducing the risk of deformation under pressure. Furthermore, when the cover 2 deforms downwards, the rubber pad 23 compresses against the goods, providing a certain shock-absorbing and cushioning effect to the surface of the goods, further reducing the risk of deformation.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
