[0004] The above-mentioned aluminum plastic plate improves the tear resistance of the whole aluminum plastic plate through the metal mesh layer, but when the aluminum plastic plate is applied to the ground or needs to bear heavy objects, the resilience of the aluminum plastic plate itself is weak, thereby easily leading to pressure loss or concave deformation, which needs to be improved.

[0005] In summary, there is a need for an anti-extrusion composite board that can improve the anti-extrusion capability. UTILITY MODEL CONTENT

[0006] The utility model discloses in order to overcome the prior art when the aluminum plastic plate is applied to the ground or needs to bear heavy objects, because the resilience of the aluminum plastic plate itself is weak, thereby easily leading to pressure loss or concave deformation, provide an anti-extrusion composite board that can improve the anti-extrusion capability.

[0007] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0008] An anti-extrusion composite board comprises:

[0009] A top plate;

[0010] A bottom plate arranged below the top plate;

[0011] An elastic layer arranged between the top plate and the bottom plate, the upper end surface of the elastic layer is fixedly connected with the bottom surface of the top plate, and the lower end surface of the elastic layer is fixedly connected with the top surface of the bottom plate.

[0012] When the top plate is subjected to external pressure or impact force, the top plate transmits the pressure to the elastic layer, and the external pressure is buffered and absorbed through the elastic deformation of the elastic layer, thereby greatly improving the anti-extrusion capability of the board, and the elastic layer pushes the top plate back to its original position through the elastic force, thereby avoiding damage or concave deformation of the board.

[0013] Preferably, the elastic layer is provided with a plurality of elastic layer through holes. The elastic layer through holes provide sufficient space for the lateral expansion of the elastic layer when the elastic layer is deformed under pressure.

[0014] Preferably, the material of the elastic layer is PVC plastic. The PVC plastic has high strength and toughness, and can withstand large pressure without breaking.

[0015] Preferably, the bottom surface of the top plate is fixed with a plurality of vertical guide columns, the inside of the bottom plate is provided with a pressure relief cavity matched with the vertical guide columns, the top surface of the pressure relief cavity is provided with vertical guide column through holes, the vertical guide columns pass through the vertical guide column through holes and are placed inside the pressure relief cavity, the vertical guide columns and the vertical guide column through holes are movably connected, the side wall of the pressure relief cavity is provided with a horizontal guide column sliding groove, the horizontal guide column sliding groove is provided with a horizontal guide column, the horizontal guide column and the horizontal guide column sliding groove are movably connected, the bottom end of the vertical guide column and the side opposite to the horizontal guide column are provided with an inclined guide surface one, the inclined guide surface one is inclined from bottom to top towards the horizontal guide column, one end of the horizontal guide column is located outside the horizontal guide column sliding groove and is provided with an inclined guide surface two matched with the inclined guide surface one, the inclined guide surface one and the inclined guide surface two are in contact, the other end of the horizontal guide column is located inside the horizontal guide column sliding groove, and the other end of the horizontal guide column and the bottom surface of the horizontal guide column sliding groove are connected through a spring. When the top plate moves downward under pressure, the vertical guide columns on the top plate also move downward, and at this time, under the guidance of the inclined guide surface one and the inclined guide surface two, most of the vertical pressure is converted into horizontal pressure, thereby greatly reducing the pressure on the bottom plate in the vertical direction and further improving the extrusion resistance of the plate. At this time, the vertical guide column pushes the horizontal guide column to move towards the bottom of the horizontal guide column sliding groove and compresses the spring, and finally the spring completes the final buffering through the elastic effect to offset the pressure, thereby greatly improving the extrusion resistance.

[0016] Preferably, the inside of the pressure relief cavity is provided with damping liquid, the side wall of the vertical guide column is fixed with a flange, the flange is placed in the pressure relief cavity and movably connected therewith, and the flange is provided with a plurality of damping liquid through holes. In the process of the downward movement of the vertical guide column, the damping force formed by the friction between the hole wall of the damping liquid through hole on the flange and the damping liquid and the internal friction between the molecules of the damping liquid can well relieve and absorb the external pressure from the vertical direction and play a damping buffering role for the movement of the vertical guide column.

[0017] Preferably, the vertical guide column and the vertical guide column through hole are movably connected through a sealing ring one. The sealing ring one can prevent the leakage of the damping liquid through the gap between the vertical guide column and the vertical guide column through hole, thereby improving the sealing performance of the plate.

[0018] As preferred, the transverse guide pillar and the transverse guide pillar sliding groove are connected through the sealing ring two. Through the design of the sealing ring two, the leakage of the damping liquid through the gap between the transverse guide pillar and the transverse guide pillar sliding groove into the transverse guide pillar sliding groove is avoided, so that the normal work of the transverse guide pillar sliding groove is affected.
