[0026] Embodiment 1

[0027] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6As shown in the figure, this device includes an upper cardboard 1 and a lower cardboard 2. The upper cardboard 1 and the lower cardboard 2 are in a parallel design state. Between the upper cardboard 1 and the lower cardboard 2, reinforcing plates 3 are fixedly arranged by gluing. On the right side of the reinforcing plate 3, there is an insertion component 4. On the left side of the outside of the upper cardboard 1 and the lower cardboard 2, there is a locking component 5. The insertion component 4 includes a first connection block 401 fixedly arranged on the right side between the upper cardboard 1 and the lower cardboard 2. On the right side of the first connection block 401, there is an insertion block 402 fixedly arranged, and at the top inside the insertion block 402, there is a jack 403 integrally arranged. The locking component 5 includes a connection strip 501 fixedly arranged on the left side of the outside of the upper cardboard 1 and the lower cardboard 2. In the middle of the connection strip 501, there is a housing 502 fixedly arranged. At the top inside the housing 502, there is a guide sleeve 503 fixedly arranged. Inside the guide sleeve 503, there is a wedge-shaped pin 504 slidingly connected. Between the top of the wedge-shaped pin 504 and the guide sleeve 503, there is a spring 505 fixedly arranged. On the left side inside the housing 502, there is a relief hole 506 integrally arranged.

[0028] The upper cardboard 1, the lower cardboard 2, and the reinforcing plates 3 are made of corrugated cardboard material, and the front cross-section of the reinforcing plate 3 is designed with a wavy trend. The outer surfaces of the upper cardboard 1, the lower cardboard 2, and the reinforcing plates 3 are coated with waterproof glue. First, through the combined design of the upper cardboard 1, the lower cardboard 2, and the reinforcing plates 3, corrugated cardboard is formed. The reinforcing plates 3 are arranged at the positions between the upper cardboard 1 and the lower cardboard 2 pairwise, so that the reinforcing plates 3 improve the overall strength of the upper cardboard 1 and the lower cardboard 2. In addition, through the design of the waterproof glue, the waterproof effect of the upper cardboard 1, the lower cardboard 2, and the reinforcing plates 3 during use is improved. When the staff needs to combine multiple corrugated cardboards, first move the insertion block 402 through the relief hole 506 into the housing 502, so that the insertion block 402 squeezes the inclined surface of the wedge-shaped pin 504 to move the wedge-shaped pin 504 upward along the direction of the guide sleeve 503, and the spring 505 deforms. Until the jack 403 and the wedge-shaped pin 504 coincide with each other, through the resilience of the spring 505, the wedge-shaped pin 504 is inserted into the jack 403, and then the state of the combined corrugated cardboard is locked.

[0029] Embodiment 2

[0030] As Figure 2 、 Figure 3 、 Figure 5As shown, a slider 6 is fixedly provided on the left side of the outside of the wedge pin 504, and the slider 6 and the wedge pin 504 are in a vertically designed state. A guide groove 7 is integrally provided at the upper end of the left side inside the housing 502. The guide groove 7 is slidably connected to the slider 6. A second connecting block 8 is fixedly provided at the top of the slider 6. An installation groove 9 is integrally provided at the left side inside the second connecting block 8. The installation groove 9 is designed with a V-shaped trend. A top pin 10 slidably penetrates through the upper end of the left side of the housing 502. Limit blocks 11 are fixedly provided at the front and rear ends on the right side of the outside of the top pin 10. An avoidance hole 12 is integrally provided at the middle end inside the upper connecting strip 501. An installation strip 13 is fixedly provided inside the avoidance hole 12. A screw pin 14 threadedly penetrates through the top of the installation strip 13. A threaded hole 15 is integrally provided at the left side inside the top pin 10. The threaded hole 15 and the screw pin 14 can be disassembled and assembled by threaded connection.

[0031] According to the operation method in Embodiment 1, when the staff needs to separate the combined corrugated cardboard, the staff first reverses the screw pin 14 to make the screw pin 14 disengage from the threaded hole 15, and then pushes the top pin 10. The top pin 10 squeezes the installation groove 9 to drive the second connecting block 8 to drive the slider 6 to move upward along the direction of the guide groove 7. The slider 6 drives the wedge pin 504 to disengage from the jack 403, and the spring 505 deforms. Then the staff can disassemble the combined corrugated cardboard. After the disassembly is completed, the staff releases the top pin 10. Through the resilience of the spring 505, the wedge pin 504 drives the slider 6 to drive the connecting block and the installation groove 9 to push the top pin 10 to reset. The limit blocks 11 can prevent the top pin 10 from disengaging from the housing 502 when it resets. When the top pin 10 resets, the staff then screws the screw pin 14 into the threaded hole 15 to fix the position of the top pin 10 and prevent the top pin 10 from being accidentally touched by an external object and moving.
