[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A wear-resistant corrugated cardboard box includes a box body 1. A symmetrical box cover 2 is rotatably connected to the upper end of the box body 1. A crease is provided at the connection between the box cover 2 and the box body 1, allowing folding. A first wear-resistant card plate 3, a second wear-resistant card plate 4, and a third wear-resistant card plate 5 are respectively provided on the front and rear ends of the left, right, and lower sides of the box body 1. A fourth wear-resistant card plate 6 is provided on the front and rear ends of the upper side of the box cover 2. The two sets of first wear-resistant card plates 3, second wear-resistant card plates 4, third wear-resistant card plates 5, and fourth wear-resistant card plates 6 are all provided at the edges of the box body 1 and the box cover 2, thereby increasing the protective effect of the box body 1. A symmetrical U-shaped block 7 is fixed on the opposite face of the first wear-resistant card plate 3, second wear-resistant card plate 4, third wear-resistant card plate 5, and fourth wear-resistant card plate 6. A locking block 8 is rotatably connected inside the U-shaped block 7 through a shaft pin.

[0027] The front and rear ends of the housing 1 are provided with four strip plates 9. The interior of each of the four strip plates 9 is slidably connected with a symmetrical insert plate 10. The other end of the insert plate 10 is provided with a cavity. The cavity is provided with a limit mechanism. The insert plate 10 is inserted into the card block 8 through the limit mechanism.

[0028] Both the front and rear sides of the box 1 are provided with handling ports, which facilitates the handling of the box 1 during use.

[0029] Both lids 2 are fixed with evenly arranged support blocks 11 on their lower sides. The two sets of symmetrical support blocks 11 are in contact with the side wall of the box body 1 on opposite sides. When a heavy object presses down on the upper end of the lid 2, the support block 11 can increase the support force of the lid 2 and prevent the lid 2 from being damaged.

[0030] The front side of the strip plate 9 is threaded with a fastening bolt 12. One end of the fastening bolt 12 extends into the inside of the strip plate 9 and engages with the insert plate 10. This allows the length of the insert plate 10 inside the strip plate 9 to be adjusted, thereby making the first wear-resistant card plate 3, the second wear-resistant card plate 4, the third wear-resistant card plate 5 and the fourth wear-resistant card plate 6 in this application suitable for various sizes of cartons.

[0031] The limiting mechanism includes two sliders 13, both of which are slidably connected to the inner wall of the cavity. A spring 14 is fixed between the two sliders 13. A pressing block 15 is fixed to the opposite side of each of the two sliders 13. A locking rod 16 is fixed to one end of the pressing block 15 on the opposite side of each of the two sliders 13. A locking groove is opened on the inner wall of the locking block 8. The locking rod 16 is inserted into the locking groove. Both the pressing block 15 and the locking rod 16 are slidably connected to the side wall of the insert plate 10.

[0032] The side walls of the first wear-resistant pallet 3, the second wear-resistant pallet 4, the third wear-resistant pallet 5, and the fourth wear-resistant pallet 6 are all fixed with rubber cushioning pads, which can increase the cushioning effect when the cartons collide with each other.

[0033] The box body 1 and the box cover 2 include two surface paper layers 17, and corrugated paper layers 18 are fixed to the inner walls of the two surface paper layers 17. A reinforcing layer 19 is fixed between the two corrugated paper layers 18.

[0034] Working principle:

[0035] When the interior of the box 1 is full of items, close the two top lids 2. Secure the two sets of first wear-resistant plates 3, second wear-resistant plates 4, third wear-resistant plates 5, and fourth wear-resistant plates 6 to the left, bottom, and right sides of the box 1 and the top of the lid 2, respectively. Move the length of the insert plate 10 inside the strip plate 9 and fix the other end of the insert plate 10 to the locking block 8 through the limiting mechanism. This limits the two sets of first wear-resistant plates 3, second wear-resistant plates 4, third wear-resistant plates 5, and fourth wear-resistant plates 6. During the use of the box 1, this can minimize the friction damage caused by the side wall of the box 1 coming into contact with other side walls of the box 1. Furthermore, when the box 1 is not in use, the first wear-resistant plates 3, second wear-resistant plates 4, third wear-resistant plates 5, fourth wear-resistant plates 6, as well as the U-shaped block 7, locking block 8, strip plate 9, and insert plate 10 can all be reused multiple times.
