Detailed Description

The invention is described in detail below with reference to the accompanying drawings, as shown in fig. 1-6: an anti-theft foot nail comprises a foot nail body 1, wherein a threaded section 11 is arranged at the front end of the foot nail body 1, a first nut 2 and a second nut 3 are connected to the threaded section 11 in a threaded manner, the first nut 2 is positioned at the front end of the foot nail body 1, a first groove 12 is formed in the threaded section 11 of the foot nail body 1, and a second groove 21 is formed in the end surface, facing the front end of the foot nail body 1, of the inner side of the first nut 2; the clamping device further comprises a clamping block 4 matched with the first groove 12 and the second groove 21, and the clamping block 4 is used for being clamped with the first groove 12 and the second groove 21.

As shown in fig. 3, the second groove 21 is a stepped groove, the second groove 21 has a first end surface 211 and a second end surface 212 along the radial direction of the first nut 2, the distance from the first end surface 211 to the axis of the first nut 2 is greater than the distance from the second end surface 212 to the axis of the first nut 2, the second end surface 212 is an inclined surface, and the second end surface 212 is fixed with the rubber pad 22.

As shown in fig. 1 and 6, the click block 4 includes a boss portion 41 and a wedge portion 42; when the wedge portion 42 moves to a position right below the second end surface 212, the inclined surface of the wedge portion 42 is pressed and attached to the rubber pad 22, the protrusion 41 is located right below the first end surface 211, and the clamping block 4 is completely located on the inner side of the first nut 2.

The working principle of the embodiment is as follows: during installation, the second nut 3 is screwed to the tail end of the threaded section 11 of the foot nail body 1, then the foot nail body 1 is inserted into a foot nail installation hole in an iron tower material, the second nut 3 is close to the foot nail installation hole, and then the first nut 2 is screwed into the threaded section 11; when the first nut 2 is screwed to be close to the foot nail mounting hole, the angle of the first nut 2 is adjusted, so that the second groove 21 is opposite to the first groove 12;

then inserting the clamping block 4 into the first groove 12, pushing the clamping block 4 to move towards the first nut 2 in the first groove 12 until the clamping block 4 enters the second groove 21, enabling the inclined wedge part 42 to be firstly contacted with the rubber pad 22, knocking the protruding part 41 along the length direction of the first groove 12 through a tool, enabling the inclined wedge part 42 to extrude the rubber pad 22 and the clamping block 4 to completely enter the first nut 2, enabling the inclined wedge part 42 to be located under the second end surface 212 at the moment, enabling the inclined plane of the inclined wedge part 42 to be extruded and attached to the rubber pad 22, enabling the protruding part 41 to be located under the first end surface 211, enabling the clamping block 4 to clamp the first nut 2, and then screwing the second nut 3 to enable the second nut 3 to tightly press tower materials, so that the iron tower is fastened;
