[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The present invention provides an embodiment of a moisture-proof cardboard box, comprising a cardboard box body 1, wherein the four outer corners of the cardboard box body 1 are fixedly connected with reinforcing plates 2. The reinforcing plates 2 are used to enhance the structural stability of the cardboard box body 1 and prevent deformation or damage during transportation and stacking. The four bottom corners of the cardboard box body 1 are fixedly connected with pads 3 (such as the attached Figure 2 As shown in the figure, the pad 3 can effectively disperse the pressure of heavy objects, prevent the bottom from being damaged by pressure, and isolate the box body 1 from moisture brought by the ground. Support plates 4 are fixedly connected to both sides of the inner wall of the cardboard box body 1. The support plates 4 can provide additional support and enhance the load-bearing capacity of the box body 1. Four connecting plates 5 are fixedly connected to the adjacent sides of the two support plates 4. The connecting plates 5 are designed in a cross shape, which can significantly improve the strength and stability of the overall structure. The outer parts of the connecting plates 5 are fixedly connected to the inner wall of the cardboard box body 1, which enables the connecting plates 5 to better bear the weight of the internal items and reduce the risk of deformation.

[0032] The inner wall of the cardboard box body 1 is fixedly connected with a limiting plate 6, which helps to keep the internal items in a fixed position to prevent collision or sliding during movement. The outer part of the limiting plate 6 is fixedly connected to the inner wall of multiple connecting plates 5. This structure increases the mutual support between the connecting plates 5 and the limiting plate 6, and improves the overall firmness (such as the attached Figure 3 Both sides of the cardboard box body 1 are fixedly connected with ventilation holes 7, which can effectively promote air circulation and avoid the formation of a humid environment inside.

[0033] refer to Figure 2The top of the cardboard box 1 is slidably connected to a closure assembly for opening the box 1. This design allows users to quickly access items inside and enhances ease of use. The closure assembly includes a lid 8, which is designed to ensure a tight closure when not in use, further protecting it from moisture. The bottom of the lid 8 is slidably connected to the top of the cardboard box 1. This sliding connection simplifies the opening operation and improves efficiency. A handle 9 is fixedly connected to the top of the lid 8, providing a convenient grip for easier transportation.

[0034] refer to Figure 4 The inner wall of the cardboard box 1 is fixedly connected to the outer layer 10. The outer layer 10 is made of polyethylene film and has excellent waterproof performance, ensuring that the items inside the box 1 will not be affected by moisture. The inner side wall of the outer layer 10 is fixedly connected to the middle layer 11. The middle layer 11 uses high-strength corrugated paper, which increases the load-bearing capacity of the box 1 while maintaining a lightweight design for easy handling. The middle layer 11 is fixedly connected to the end away from the outer layer 10 with a vacuum layer 12. The presence of the vacuum layer 12 significantly reduces the transfer of external moisture and effectively prevents items from getting damp. The vacuum layer 12 is fixedly connected to the end away from the middle layer 11 with an inner layer 13. The inner layer 13 is made of aluminum foil, which further enhances the moisture-proof effect and can reflect external heat to protect internal items from temperature changes.

[0035] Working Principle: The moisture-proof cardboard box relies on the synergistic effect of multiple structural components to ensure effective protection of the contents. The cardboard box body 1 serves as the core structure, offering excellent load-bearing and pressure-resistant properties. External reinforcement panels 2 enhance the box body's stability, preventing deformation during transport and stacking. The bottom pad 3 effectively distributes the pressure of heavy objects, ensuring resistance to breakage under pressure.

[0036] The inner wall support plates 4 provide additional support, increasing the load-bearing capacity of the box 1 and ensuring stability. The cross-shaped design of the connecting plates 5 significantly enhances overall strength, helps evenly distribute the load, and reduces the risk of deformation. The restraining plates 6 secure the contents to prevent damage from collisions or sliding.

[0037] To prevent moisture, vents 7 are provided on both sides of the cardboard box body 1 to promote air circulation and facilitate transportation. The box cover 8 in the closure assembly can be tightly closed to further enhance the moisture-proof effect, and the handle 9 on the top is easy to open and enhance the convenience of use.

[0038] The outer layer 10 is made of polyethylene film, which has excellent waterproof properties and effectively isolates external moisture. The inner middle layer 11 uses high-strength corrugated paper to increase load-bearing capacity while maintaining lightweight. The vacuum layer 12 outside the middle layer 11 significantly reduces the transmission of external moisture by forming an air layer, effectively preventing items from getting wet.

[0039] The inner layer 13 is made of aluminum foil to further enhance the moisture-proof effect, while reflecting external heat to prevent internal temperature fluctuations. The moisture-proof cardboard box forms an efficient moisture-proof structure through the reasonable layout and material selection of each structure, ensuring the safety and integrity of the internal items under different environmental conditions.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
