As shown in fig. 1 to 3, the present application provides an anti-skid structure 100. This antiskid line structure 100 includes substrate layer 1, the surface of substrate layer 1 is provided with a plurality of polygonal lugs 2, and every lug 2 is the same completely. Each lug 2 is arranged to protrude out of the outer surface of the substrate layer 1. Extending outwards from the top corner of the polygonal bump 2 to form an extension 22. In a specific embodiment, the bump 2 is square, one end of each side of the square extends outwards along the direction of the side to form an extension portion 22, and the extension portions 22 on the four sides of the square are spiral in the clockwise or counterclockwise direction.

The anti-skid texture structure 100 is composed of an array formed by a plurality of square protrusions, one end of each side of each square extends outwards to form an extension part 22, and the extension parts 22 of four sides of each square are screwed along the same direction. By adopting the anti-skid texture structure 100, the friction force can be increased, and the hand feeling of touching the anti-skid texture structure 100 is better.

In the present embodiment, the bump 2 has a hollow portion 23, and the hollow portion 23 is communicated with the outer surface of the substrate layer 1.

The middle of each square bump 2 is hollow, so that the hollow part 23 and the substrate layer 1 connected with the hollow part form a concave part, when an operator tightly holds the anti-skid texture structure 100, the concave part can generate negative pressure, the holding force is further improved, and the anti-skid texture structure is not easy to slip.

Specifically, as shown in fig. 2, the ratio of the length L1 of the side 21 of the square of the bump 2 to the length L2 of the extension 22 is 1.5-2. The length L1 of the square edge 21 of the projection 2 in this ratio is adapted to the length L2 of the extension 22 to ensure that the friction and grip are well within the performance limits.
