A partition board is attached to the inside of the cardboard box via long strip Velcro. Limiting blocks are installed at the inner corners of the side box panel via fixing bolts. A support rod is inserted into the inner side of the limiting block. X-shaped reinforcing plates are inserted into the upper and lower ends of the support rod. The X-shaped reinforcing plates are respectively embedded and attached to the surfaces of the lower box panel and the upper box panel.

[0006] Furthermore, a first cut is provided on the front surface of the cardboard box; and the first cut is located at the upper and lower ends of the second cut.

[0007] Furthermore, long strips of Velcro are glued to the inner surfaces of the front and rear sides of the cardboard box; and the long strips of Velcro are arranged at equal intervals.

[0008] Furthermore, adhesive strips are glued to both the front and rear ends of the partition plate, and the adhesive strips are correspondingly glued to the long strip of Velcro.

[0009] Furthermore, the central layer of the partition plate is provided with a double-layer film; and the films are bonded together with a small amount of adhesive.

[0010] Furthermore, the surface of the X-shaped reinforcing plate is provided with insertion holes; and a support rod is inserted into the insertion holes.

[0011] Furthermore, a connecting stud is fixed to one end of the support rod, and a threaded groove is provided on the other end of the rod.

[0012] The beneficial effects of this utility model are as follows: The multi-purpose modular cardboard packaging box utilizes two sets of partitions inside the cardboard box, which are then bonded to long strips of Velcro inside the box, creating two independent spaces within the box. This effectively stores and packages multiple goods, enhancing the flexibility of large-sized cardboard packaging boxes for combined storage. By cutting the cardboard box along the second cut line on its surface, two slightly flattened rectangular storage boxes are formed. After the two sets of partitions are torn apart, they are bonded to the open end of the rectangular packaging box as lids, facilitating further reuse of the cardboard packaging box. This design provides both household and storage uses, increasing the utilization rate of the modular cardboard packaging box. The internal reinforcement structure of the cardboard packaging box is formed by connecting X-shaped reinforcing plates, support rods, and limiting blocks, dispersing the stress on the cardboard packaging box and improving its resistance to pressure and impact.
