[0008] Furthermore, a tooth block is provided on the inner wall of the annular block, and the tooth block on the inner wall of the annular block can conveniently and effectively improve the anti-slip effect after the steel cable passes through the through hole.

[0009] Furthermore, the annular block and the tooth block are both made of stainless steel. The annular block and the tooth block made of stainless steel have good strength and good reliability when used.

[0010] Furthermore, the outer surface of the anchor pad is provided with a galvanized layer.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model provides an anti-skid anchor. The displacement column is exerted with a force toward the center of the anchor pad under the action of a cylindrical spring, so that the annular block is used to exert a compacting force on the steel cable. Through the tooth block inside the annular block and the first anti-skid teeth and the second anti-skid teeth inside the jacket, the anti-skid anchor has multiple groups of anti-skid structures, which can conveniently and effectively provide a reliable anti-skid effect for the steel cable passing through the anchor.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-3 As shown, an anti-skid anchor comprises an anchor pad 1, an annular block 4, a displacement column 7 and a jacket 6, wherein a through hole 2 is penetrated through one end of the anchor pad 1 near the edge, a jacket 6 is arranged on the outer side of one end of the through hole 2, a reserved groove 3 which is arranged to penetrate the through hole 2 is arranged on the outer periphery of the anchor pad 1, a displacement column 7 is connected to the inner wall of the reserved groove 3 through a cylindrical spring 8, an annular block 4 is welded to the end of the displacement column 7, and the annular block 4 is located in the through hole 2, a first anti-skid tooth 9 is arranged on the inner wall of the jacket 6 near the end, and a second anti-skid tooth 10 is arranged on the inner wall of the jacket 6 away from the first anti-skid tooth 9.

[0019] Wherein, a tooth block 5 is arranged on the inner wall of the annular block 4 .

[0020] In this embodiment, Figure 1 and Figure 2 As shown, the tooth block 5 on the inner wall of the annular block 4 can effectively and conveniently improve the anti-slip effect of the steel cable after passing through the through hole 2.
