In the figure: the bolt comprises a bolt body 1, a round cap 2, a regular hexagonal groove 3, a slot 4, a through hole 5, a clamping piece 6, a rod body 7, an installation groove 8, an elastic piece 9, a clamping column 10 and a limiting bolt 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-8, a locking theftproof high strength bolt, including bolt 1, fastener 6, bolt 1 top is fixed and is equipped with round cap 2, round cap 2 top is opened has regular hexagonal groove 3, the bottom is opened in regular hexagonal groove 3 has slot 4 with 6 looks adaptations of fastener, open on the inner wall of slot 4 lower part has two symmetry setting's perforating hole 5, fastener 6 sets up the bottom in slot 4, the both sides of fastener 6 all open and have mounting groove 8 corresponding with perforating hole 5, elastic component 9, card post 10 are inserted in proper order to the bottom in mounting groove 8, the terminal surface in the card post 10 outside is equipped with the cockscomb structure latch, the cockscomb structure latch can be with card post 10.

6 upper surface both sides of fastener all run through and are provided with spacing bolt 11, and the equal threaded connection in spacing bolt 11 bottom is on the card post 10 that corresponds, and after filling in mounting groove 8 with elastic component 9, will block post 10 with power and fill in, utilize spacing bolt 11 will block post 10 fixed afterwards to prevent to block post 10 and pop out.

A rod body 7 is fixedly arranged at the center of the upper surface of the clamping piece 6, and a stop block 12 is fixedly arranged at the top end of the rod body 7. Through setting up dog 12, when inserting fastener 6 in slot 4 and fixed, dog 12 on the body of rod 7 top is stopped up most space in regular hexagon groove 3 to make the external world can't twist the bolt with the help of the instrument.
