[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an antistatic PVC foam board of the present invention includes a limiting plate 2, a fixed plate 3 and a plurality of PVC foam boards 1. The limiting plate 2 and the plurality of PVC foam boards 1 are arranged horizontally. Grooves 5 are provided on the bottom surfaces of the limiting plate 2 and the plurality of PVC foam boards 1. The plurality of grooves 5 are combined to form a horizontally arranged connection groove 8. The fixed plate 3 is arranged in the connection groove 8. Fixed blocks 6 are embedded in the middle of the grooves 5. A connection groove 8 is provided on the bottom surface of the fixed block 6. A connection block 9 is inserted into the connection groove 8. The bottom surface of the connection block 9 is mounted on the fixed plate 3.

[0027] In this embodiment, one end of the connection groove 8 expands outward to form an in-and-out groove 7 for the connection block 9 to disengage from the fixed block 6. The width of the in-and-out groove is greater than the width of the connection block 9.

[0028] In this embodiment, the plurality of PVC foam boards 1 are in contact with each other. One end of the limiting plate 2 is in contact with the end face of the adjacent PVC foam board 1. The other end of the limiting plate 2 is fixedly connected to the fixed plate 3 through a torsion spring hinge.

[0029] The length of the fixed plate 3 matches the sum of the lengths of the limiting plate 2 and the plurality of PVC foam boards 1.

[0030] In this embodiment, the cross-sections of the connection groove 8 and the connection block 9 are both arranged in a trapezoidal structure, and the plugged PVC foam board can be positioned by the connection groove and the connection block to avoid separation from the fixing plate.

[0031] In this embodiment, the bottom surface of the fixing plate 3 is flush with the bottom surface of the PVC foam plate 1 and the bottom surface of the limiting plate 2, which increases the flatness after installation and avoids unevenness.

[0032] In this embodiment, a plurality of fixing holes 4 are provided on the fixing plate 3, and screws can pass through the fixing holes to fix the fixing plate at any position.

[0033] In this embodiment, the limit plate 2 is made of a foam board, and a metal spring sheet is installed inside the limit plate 2, wherein the foam board has a certain elasticity, and the metal spring sheet increases the firmness of the foam board to avoid breakage, and the limit plate can be directly lifted upward with the torsion spring hinge as the center by bending, wherein the limit plate can protrude from one end face of the PVC foam board toward the PVC foam board to form a plurality of card blocks, and a plurality of card slots matching the card blocks are provided on the end faces of adjacent PVC foam boards, and the card blocks can be inserted into the card slots, and the positioning effect of the limit plate is increased by card connection.

[0034] In this embodiment, the PVC foam board 1 is an antistatic PVC foam board. As a common material, the antistatic PVC foam board has many advantages, such as antistatic, fireproof, high strength, and not easy to deform.

[0035] During installation, first put the PVC foam board on the fixing board through the groove, insert the connecting block into the inlet and outlet groove, and push the PVC foam board to the right along the fixing board. After the PVC foam board moves to the right, the connecting block can be directly inserted into the connecting groove. The PVC foam board can be directly positioned through the connecting groove and the connecting block of the trapezoidal structure. After covering the limit plate, the limit plate can position the leftmost PVC foam board so that the PVC foam board cannot move to the left, thereby ensuring the stability of the installation.

[0036] On the contrary, when disassembling, the limit plate can be opened upward with the torsion spring hinge as the center. After losing the obstruction of the limit plate, the PVC foam board can move to the left along the fixed plate, so that the connecting block is disengaged from the connecting groove and enters the entry and exit groove, thus completing the disassembly of the PVC foam board and greatly increasing the efficiency of installation and disassembly.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
