[0002] In the field of modern logistics and commodity packaging, packaging boxes serve as an important tool for protecting goods and facilitating transportation and storage. However, existing packaging boxes still have some shortcomings in terms of pressure resistance, portability, internal space utilization, and assembly and storage. On the one hand, many traditional packaging boxes cannot effectively buffer and disperse the force when faced with external impacts and compression, making the contents easily damaged. Although some packaging boxes use simple cushioning materials, such as foam pads, the cushioning effect of these materials is limited and it is difficult to flexibly adjust them according to different packaging needs. On the other hand, the assembly process of some packaging boxes is complicated, requiring multiple tools and a lot of time, which increases packaging and time costs. Moreover, most packaging boxes occupy a lot of space when not in use, making them inconvenient for transportation and storage, thus increasing the operating costs of enterprises.
