[0022] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a Wantong board with good toughness, including a surface layer 1, a connecting box 2 is fixedly connected to the right side of the surface layer 1, two moving parts 10 are slidably connected inside the connecting box 2, the adjacent sides of the two moving parts 10 are rotatably connected with a connecting rod 13, a pressing block 3 is rotatably connected between the tops of the two connecting rods 13, the top of the pressing block 3 passes through and extends to the top of the connecting box 2, the pressing block 3 is slidably connected to the connecting box 2, the two moving parts 10 are fixedly connected to a locking piece 4 on the right side, the bottom of the pressing block 3 is fixedly connected to a spring 11, and the bottom end of the spring 11 is fixedly connected to the inner wall of the connecting box 2.

[0023] Specifically, pressing the pressing block 3 squeezes the spring 11, and the pressing block 3 drives the connecting rod 13 to move. The two connecting rods 13 push open the moving parts 10 on both sides, and the two moving parts 10 drive the locking parts 4 to separate. At this time, the two locking parts 4 are inserted into the connecting groove 14 on the connecting block 8. At this time, the pressing block 3 is released. Under the action of the spring 11, the pressing block 3 is pushed up, so that the two locking parts 4 are brought together, realizing the rapid splicing between the two Wantong plates.

[0024] Reference Figure 1 The bottom of the surface layer 1 is fixedly connected to the middle layer 5 , the bottom of the middle layer 5 is fixedly connected to the bottom layer 7 , and a plurality of through holes 6 are opened between the front and back sides of the middle layer 5 .

[0025] Specifically, the multi-layer composite structure can effectively disperse stress, reduce stress concentration, and improve the overall reliability and durability of the plate.

[0026] Reference Figure 2 A connecting block 8 is fixedly connected to the left side of the surface layer 1, and two connecting grooves 14 are opened on the left side of the connecting block 8.

[0027] Specifically, the two connecting grooves 14 are L-shaped, and the two locking members 4 are inserted therein for connection and fixation.

[0028] Reference Figure 3 A card slot 12 is provided on the rear side of the connection box 2 and the connection block 8 .

[0029] Specifically, the card slot 12 is used for splicing the front and rear Wantong boards to prevent the front and rear Wantong boards from shifting left and right.

[0030] Reference Figure 1 The connection box 2 and the front side of the connection block 8 are fixedly connected with a fixing block 9, and the fixing block 9 has the same size as the card slot 12 and the through hole 6.

It can also provide certain wear resistance and scratch resistance to protect the underlying layer.

[0034] Reference Figure 1 The middle layer 5 is made of polycarbonate and the bottom layer 7 is made of glass fiber reinforced nylon.

[0035] Specifically, the middle layer 5 made of polycarbonate has high strength and rigidity; when the impact energy is transmitted to this layer, it can resist large loads, prevent the rapid expansion of cracks, and transfer part of the energy to the lower layer, while cooperating with the first layer to disperse stress. The bottom layer 7 made of glass fiber reinforced nylon has strength and hardness, providing the main support and bearing capacity for the entire structure. It can effectively disperse and withstand internal stress, ensuring that the Wantong board will not easily deform or break during normal use and when subjected to large impacts.

[0038] Working principle: When in use, press the pressing block 3 to squeeze the spring 11, and the pressing block 3 drives the connecting rod 13 to move. The two connecting rods 13 push open the moving parts 10 on both sides, and the two moving parts 10 drive the locking parts 4 to separate. At this time, the two locking parts 4 are inserted into the connecting groove 14 on the connecting block 8. At this time, release the pressing block 3. Under the action of the spring 11, the pressing block 3 is pushed up, so that the two locking parts 4 are brought together, realizing the rapid splicing between the left and right Wantong boards. When the front and rear Wantong boards are spliced, the rear fixing block 9 is inserted into the slot 12 or through hole 6 on the front Wantong board to prevent the front and rear Wantong boards from offsetting. The Wantong board composed of the surface layer 1, the middle layer 5 and the bottom layer 7, this multi-layer composite structure can effectively disperse stress, reduce stress concentration, and improve the overall reliability and durability of the board.
