[0013] Preferred configuration: Corrugated cardboard is placed on the inner bottom of the box, and several corrugated paper strips are fixedly connected to the bottom of the corrugated cardboard. When it is necessary to store items, the corrugated cardboard is first placed on the inner bottom of the box, and the corrugated paper strips play a cushioning role.

[0014] Preferably, grooves are formed between the concave cardboard and the four inner sidewalls of the box lid.

[0015] Preferably, the lid is connected to the opening of the box body by compression through a groove.

[0016] Preferably, the four triangular blocks are engaged with the four slots respectively.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] I. This application, by setting up a box lid, concave cardboard, and corrugated cardboard, provides a first layer of protection. If the box lid is damaged by external factors, the inner box body can also provide protection. If the top surface of the box lid is damaged, the concave cardboard can provide protection. If the bottom of the box body is damaged, the corrugated cardboard can also provide protection. This prevents external impurities from entering the box body and damaging the contents, thus solving the problem that existing corrugated cardboard boxes are easily affected by external interference when damaged, resulting in poor performance.

[0019] Second, with this application, only the corrugated cardboard needs to be placed inside the box, and then the box lid can be directly put on the open end of the box to complete the assembly. Compared with the existing folding corrugated cardboard boxes, this application is more convenient to assemble, giving it the advantage of being easy to use. Attached Figure Description
