[0023] Based on this, in order to improve the insufficient strength of the packaging box in the related art, which causes the bottom packaging box to be damaged during the stacking process, resulting in damage to the goods in the packaging box and economic loss, the embodiments of the present application provide the following solutions.

[0024] Please refer to Figures 1-4, including a packaging box body 1, the packaging box body 1 includes an outer box body 13, an inner box body 12, a bottom plate 11, a cover plate 15 and a support assembly 14, the support assembly 14 includes a support column 141, the outer box body 13 and the inner box body 12 are bonded on the bottom plate 11, the cover plate 15 is rotationally connected on the outer box body 13, the outer box body 13 is sleeved on the inner box body 12, a placing cavity 16 is formed between the outer box body 13 and the inner box body 12, the support column 141 is arranged in the placing cavity 16, the outer periphery of the support column 141 abuts against the outer wall of the inner box body 12 and the inner wall of the outer box body 13, the lower end of the support column 141 abuts against the bottom plate 11, and the upper end of the support column 141 is flush with the upper edge of the outer box body 13 and the inner box body 12.

[0025] In this way, when the packaging box is used, the articles to be sent are placed in, the cover plate 15 is rotated to completely cover above the outer box body 13, and then a plurality of turns of adhesive tape is wound on the sealing portion, so that the packaging box can be sent out safely, the placing cavity 16 formed between the outer box body 13 and the inner box body 12 is internally provided with a plurality of support columns 141, the lower end of the support column 141 abuts against the bottom plate 11, and can provide firm bottom support, and the upper end of the support column 141 is flush with the upper edge of the outer box body 13 and the inner box body 12, so that the outer box body 13, the inner box body 12 and the support column 141 can share the great pressure that the packaging box may be subjected to during stacking and transportation, and prevent the packaging box from collapsing due to heavy pressure, so as to damage the articles in the packaging box, and meanwhile, the support column 141 can give the packaging box a pressure resistance on the side surface due to the cylindrical characteristic, so as to enhance the stability of the packaging box when subjected to lateral extrusion, and thus increase the anti-deformation ability of the packaging box as a whole.

[0026] Optionally, in some embodiments, referring to Figures 1-3 , the four corners of the packaging box body 1 are provided with corner guards 2, and the corner guards 2 abut against the bottom plate 11 and the outer box body 13.

[0027] In this way, the corner guards 2 can tightly wrap the edges and corners of the packaging box, and these areas are most likely to be subjected to collision and extrusion during transportation and handling, and the corner guards 2 form a firm protective barrier, effectively avoiding the damage of the edges and corners, so as to protect the products in the packaging from damage, and meanwhile, the corner guards 2 have good buffering performance, and when external impact force acts on the packaging box, the corner guards 2 can quickly absorb and disperse the force, reducing the damage to the internal goods, and this buffering effect is particularly important for protecting fragile and high-value articles.

[0028] Optionally, in some embodiments, referring to Figure 1 , Figure 3 and Figure 4The support assembly 14 further comprises a support plate 142 and a support strip 143, the inner wall of the inner box body 12 is provided with a sliding groove, the support plate 142 is in sliding connection with the inner box body 12, one end of the support plate 142 is in abutment with the bottom plate 11, the other end of the support plate 142 is flush with the upper edge of the inner box body 12, the inner box body 12 is further provided with a placing groove, the bottom plate 11 is internally provided with a cavity, the support strip 143 is composed of a plurality of transversely and longitudinally arranged strip-shaped hard materials, and the support strip 143 is arranged in the cavity and in abutment with the inner wall of the cavity of the bottom plate 11.

[0029] In this way, the support plate 142 slides on the inner box body 12 through the sliding groove, so as to divide the internal space of the packaging box into two parts. The internal space of the packaging box is originally a cuboid space, which is divided into two cubes by the support plate 142. The cube has stronger stability than the cuboid. The cuboid is prone to deformation on the long side. Meanwhile, the support plate 142 has a similar effect to the support column 141 and shares the great pressure that the packaging box may be subjected to during stacking and transportation with the support column 141, so as to prevent the packaging box from collapsing due to heavy pressure and damaging the goods in the packaging box. The bottom plate 11 is internally provided with a cavity, and the support strip 143 is arranged in the cavity. The support strip 143 is made of carbon fiber material and has strong rigidity and light weight, and is mainly used to enhance the compression resistance of the side of the packaging box. The presence of the support strip 143 can prevent the packaging box from deforming when subjected to lateral extrusion to the greatest extent. Meanwhile, the inner box body 12 is further provided with a placing groove for placing the support plate 142. When the goods in the packaging box are relatively large, the support plate 142 is temporarily not needed, and the support plate 142 can be inserted into the placing groove. When the packaging box is used next time, if the support plate 142 is needed, the support plate 142 is taken out from the placing groove, and the internal space of the packaging box is divided through the sliding groove.

[0030] Optionally, in some embodiments, referring to Figure 2 The bottom plate 11 is further attached with a reinforcing rib 3, the reinforcing rib 3 is arranged in a diagonal line, and the reinforcing rib 3 is in abutment with the corner guard 2.

[0031] Thus, due to the design of the corner protector 2, the bottom plate 11 is effectively lifted, thereby avoiding direct contact with the ground or table surface, and is in a suspended state. This design is not only beautiful, but also practical, and the suspended bottom plate 11 can effectively avoid water stains on the table surface or ground. The reinforcing rib 3, as a structural supplement, is located between the gap between the bottom plate 11 and the table surface or ground, not only ensuring the stability of the package, but also further improving the overall load-bearing capacity. At the same time, the introduction of the reinforcing rib 3 also significantly enhances the ability of the packaging box to resist pressure from the side direction, making the entire packaging structure more solid and durable, better protecting the internal items from external impact and pressure, thereby ensuring the safety and integrity of the product.

[0032] Optionally, in some embodiments, referring to Figure 4 , the cavity inside the bottom plate 11 and the placement cavity 16 are filled with waterproof material 4.

[0033] Thus, the packaging box is easily eroded by water, and excessive humidity can cause problems such as deformation, wrinkling, delamination, and cracking of the packaging material, affecting the appearance of the package, reducing its load-bearing performance, causing the carton to collapse during loading or transportation, causing damage to the goods and hindering transportation. The waterproof material 4 can avoid such situations as much as possible. The filled waterproof material 4 can be one or more of polyethylene (PE) and polypropylene (PP) plastic film, EPE pearl wool, and polystyrene foam, wherein the EPE pearl wool has excellent waterproof performance, as well as excellent shock and pressure resistance.

[0034] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
