[0035] By the layout of vertical reinforcing rib one 6, horizontal reinforcing rib one 7, vertical reinforcing rib two 9 and horizontal reinforcing rib two 10 in the bottom and inside of box body 1, and the inner wall of box body 1 is equipped with support block 8, vertical reinforcing rib one 6 and vertical reinforcing rib two 9 effectively disperse and transmit pressure and impact force from above or below by virtue of their structural characteristics, to avoid excessive deformation of box body 1 in the vertical direction;Horizontal reinforcing rib one 7 and horizontal reinforcing rib two 10 form a powerful support in the horizontal direction, resist the extrusion, collision and other external forces in each horizontal direction during transportation and storage, prevent box body 1 from twisting and deforming, vertical and horizontal reinforcing ribs are staggered with each other, so that the support effect in different directions is complementary, a stable mechanical framework is built in three-dimensional space, support block 8 is closely attached to the inner wall of box body 1, the internal support strength is enhanced, the stress concentration points of key stress points are dispersed, the deformation of box body 1 caused by excessive local stress is prevented, through the coordinated cooperation of the series of structures, the overall strength of the packing box is significantly improved, which can effectively cope with complex external forces and minimize the risk of deformation of box body 1 due to external forces, to provide reliable protection for internal goods.

[0036] With reference to Figure 4The composite assembly 11 includes a smooth sealing layer 12 arranged inside the box body 1, which is made of polyethylene and used to provide wear resistance and sealing of the smooth sealing layer 12. The composite assembly 11 includes a buffer energy absorption layer 13 arranged at the bottom of the smooth sealing layer 12, which is made of foamed polystyrene and used to provide the buffer property of the buffer energy absorption layer 13. The composite assembly 11 includes a high-strength protective layer 14 arranged at the bottom of the buffer energy absorption layer 13, which is made of carbon fiber and used to provide the tensile resistance of the high-strength protective layer 14.

[0037] The composite assembly 11 composed of the high-strength protective layer 14, the buffer energy absorption layer 13 and the smooth sealing layer 12 is arranged inside the box body 1 to build a comprehensive protection system for the packaging box. The high-strength protective layer 14 is made of carbon fiber material and has high strength and tensile resistance, which can effectively resist large external impact and extrusion and prevent the box body 1 from being damaged by external force. The buffer energy absorption layer 13 is made of foamed polystyrene material, which has a porous structure and good buffer property. After the impact force passes through the high-strength protective layer 14, the buffer energy absorption layer 13 absorbs and disperses the remaining impact force, so that the impact force does not directly act on the internal articles, further reducing the risk of damage to the articles. The smooth sealing layer 12 is made of food-grade polyethylene material, which has a smooth surface and flexibility. It can not only prevent the internal articles from being scratched, but also has good sealing performance. After the articles are placed in the box body 1, the smooth sealing layer 12 can tightly cooperate with the sealing rubber strip 3 in the box cover 2 to effectively block the invasion of external factors such as dust and moisture, maintain a good environment inside the packaging box, and realize high toughness and high sealing performance through the synergistic effect of the three layers of structure, thereby providing comprehensive and reliable protection for the internal articles and greatly reducing the damage probability of the articles during transportation and storage.

[0038] Referring to Figure 1 The box body 1 is slidingly connected to the bottom of the box cover 2. The top of the box cover 2 is fixedly connected with a handle 15 and an exhaust port 16. The middle of the exhaust port 16 is equipped with a knob 17.

[0039] The sliding connection of the box body 1 and the bottom of the box cover 2 makes the opening and closing operation more smooth, avoiding structural damage caused by frequent opening and closing. The handle 15 on the top of the box cover 2 facilitates carrying, disperses the force point and enhances stability. The exhaust port 16 and the knob 17 improve the convenience of use and enhance the protection of the articles, meeting various needs.

[0040] Working principle: when in use, the articles are placed in the box body 1. The internal smooth sealing layer 12 prevents scratching and cooperates with the sealing rubber strip 3 in the box cover 2 to preliminarily protect the articles. Then, the box cover 2 is closed, and the box body 1 is tightly connected with the box cover 2 through the friction clamping structure. At the same time, the sealing rubber strip 3 is deformed to fill the gap and block the invasion of dust and moisture.

[0041] In the transportation or storage, if the box 1 is collided and extruded, the vertical reinforcing ribs 6, the horizontal reinforcing ribs 7, the vertical reinforcing ribs 9 and the horizontal reinforcing ribs 10 in the bottom and the inside of the box 1 are supported alternately, the vertical reinforcing ribs resist the vertical external force, the horizontal reinforcing ribs increase the horizontal stability, the support blocks 8 support the inner wall of the box 1, and the strength of the packaging box is improved comprehensively to prevent the deformation of the box 1;

[0042] If the humidity in the box is increased, the rotating exhaust port 16 and the knob 17 discharge the moisture, the knob 17 is rotated to be sealed after the humidity is normal, the high-strength protective layer 14 of the box 1 resists the collision and extrusion, the buffer energy-absorbing layer 13 absorbs and disperses the impact force, and the soft sealing layer 12 prevents scratching and sealing.

[0043] It should be finally pointed out that the above description is only the preferred embodiments of the utility model and is not used for limiting the utility model, although the utility model is described in detail by referring to the foregoing embodiments, the technical scheme recorded in the foregoing embodiments can be modified or the equivalent replacement of some technical features can be made for the person skilled in the art, any modification, equivalent replacement, improvement and the like made in the spirit and principle of the utility model should be included in the protection scope of the utility model.
