Description

TECHNICAL FIELD

[0001] The utility model relates to the field of anti-fatigue pad, in particular to a kind of elastic anti-fatigue pad. BACKGROUND

[0002] In order to improve the anti-fatigue effect of the anti-fatigue pad, the elasticity of the anti-fatigue pad needs to be increased, so that the human body can be buffered and damped when stepping on the anti-fatigue pad.

[0003] PU foam is rich in elasticity and can be used as an anti-fatigue pad, but PU foam has poor wear resistance and is easily worn out when wearing shoes and stepping on it. Moreover, it is not easy to clean. Therefore, a wear-resistant and easy-to-clean surface layer can be added on the top surface of the PU foam. Since PU foam and the surface layer are made of different materials, they cannot be formed at one time and need to be assembled and fixed. In the prior art, glue is often used to fix PU foam and the surface layer, which is not environmentally friendly and cannot be disassembled for separate maintenance, which is costly and needs to be improved. SUMMARY

[0004] The technical problem solved by the utility model is to provide an elastic anti-fatigue pad that improves the convenience of assembly and disassembly and ensures elasticity and anti-fatigue effect.

The top surface of the elastic core layer pad is provided with first positioning holes at intervals. The bottom surface of the elastic core layer pad is provided with second positioning holes corresponding to the first positioning holes in a one-to-one correspondence. The lock comprises a first positioning sleeve and a second positioning sleeve. The second positioning sleeve is arranged in the second positioning hole. The first positioning sleeve is concentrically arranged on the second positioning sleeve and extends upward into the first positioning hole. The inner diameter of the first positioning sleeve is smaller than the inner diameter of the second positioning sleeve to form a stepped hole. The bottom of the elastic core layer pad is provided with self-locking pieces corresponding to the first positioning holes in a one-to-one correspondence. The self-locking pieces comprise two symmetrically distributed elastic rods. The elastic rods extend along the inner wall of the first positioning sleeve into the second positioning sleeve. The outer side of the elastic rod is provided with a wedge extending to the step of the stepped hole.

[0006] In a preferred embodiment of the utility model, the diameter of the first positioning hole is smaller than the diameter of the second positioning hole.

[0012] In a preferred embodiment of the present application, the surface layer pad is provided with a clamping groove in the bottom of the two adjacent edges, and the other two edges are provided with a clamping buckle corresponding to the clamping groove.

[0013] In a preferred embodiment of the present application, the top surface of the surface layer pad is provided with anti-skid ribs at intervals.

[0014] The present application has the advantages that: the elastic fatigue-resistant pad provided by the present application is locked by the cooperation of the lock buckle and the self-locking part after the elastic core layer pad is inserted into the embedding groove in the bottom surface of the surface layer pad, which avoids the separation of the elastic core layer pad and the surface layer pad, and the assembly and disassembly of the lock buckle and the self-locking part are convenient, which does not affect the separate replacement of the surface layer pad or the elastic core layer pad, reduces the use cost, and the lock buckle does not affect the downward deformation of the surface layer pad when it is stepped on, which ensures the elasticity and fatigue-resistant effect.
