[0019] The principles and characteristics of the utility model are described below in conjunction with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model.

[0020] As Figures 1-4 Shown, a kind of anti -pulling anchor structure, including anchor body 1, the lower end outside of anchor body 1 is arranged with multiple groups of anti -pulling mechanism along the axial direction. Anti -pulling mechanism includes cylindrical pipe part 8 and the inner recess ring 2, outer convex ring 3 arranged in periphery, and the inner recess ring 2, outer convex ring 3, cylindrical pipe part 8 in each group of anti -pulling mechanism are sequentially arranged from top to bottom.

[0021] The cross section circle radius of inner recess ring 2 decreases from top to bottom, and the outer diameter of inner recess ring 2 is less than the outer diameter of anchor body 1. When anchor body 1 is subjected to upward tension, the anchor end surface of inner recess ring 2 lower end can produce greater resistance between the stratum, to improve the anti -pulling performance of anchor body 1.

[0022] The cross section radius of the outer convex ring 3 decreases from top to bottom, and the outer diameter of the outer convex ring 3 is larger than the outer diameter of the anchor rod body 1. When the anchor rod body 1 is subjected to upward pulling force, the anchor rod end surface at the upper end of the outer convex ring 3 will generate larger resistance with the stratum, so as to improve the pulling resistance of the anchor rod body 1.

[0023] Further, the outer side of the cylindrical pipe part 8 is provided with a plurality of inner concave holes 4, which can increase the friction between the cylindrical pipe part 8 and the stratum.

The pulling resistance mechanism on the anchor rod body 1 is an integral structure. The anchor rod body 1 is a concrete structure, and a plurality of steel bars are embedded in the inner part in the axial direction, so as to ensure the structural strength.

Preferably, the planes where the radial positioning plates 5 are located all intersect at the central axis of the anchor rod body 1. When the anchor rod body 1 is subjected to radial external force, the radial positioning plates 5 and the inner concave holes 4 can improve the radial rotation resistance, so as to improve the radial stability of the anchor rod body 1.
