Description

Locking theftproof high strength bolt

Technical Field

The invention relates to the technical field of bolts, in particular to a locking anti-theft high-strength bolt.

Background

The anti-theft bolt, bolts, nuts and tools used for iron towers, metal frameworks, high-pipe guardrails and the like which are arranged outdoors at present are all common types, and even if the anti-theft bolt is special for anti-theft, the popularization and the use are influenced due to the reasons of high price, difficulty in secondary fastening, easiness in loosening and the like, so that the iron towers, the transformers, the guardrails and important facilities are easy to steal and disassemble. The anti-loose anti-theft high-strength bolt is designed to solve the problems.

Disclosure of Invention

The invention aims to solve the defect that the anti-loose and anti-theft effect needs to be improved in the prior art, and provides an anti-loose and anti-theft high-strength bolt.

In order to achieve the purpose, the invention adopts the following technical scheme:

the design is a locking theftproof high strength bolt, including bolt, fastener, the fixed round cap that is equipped with in bolt top, open on the round cap top has regular hexagonal groove, the bottom is opened to regular hexagonal inslot bottom has the slot with fastener looks adaptation, it has the perforating hole that two symmetries set up to open on the inner wall of slot lower part, the fastener sets up the bottom in the slot, the both sides of fastener are all opened the mounting groove corresponding with the perforating hole, bottom inserts elastic component, card post in the mounting groove in proper order, fastener upper surface both sides all run through and are provided with spacing bolt, the equal threaded connection in spacing bolt bottom is on the card post that corresponds, the middle fixed body of rod that is equipped with of department of fastener upper surface.

Preferably, the surface of the tail end of the outer side of the clamping column is provided with saw-toothed clamping teeth.

Preferably, the elastic member may be an elastic rubber column.

Preferably, a stop block is fixedly arranged at the top end of the rod body.

The anti-loose anti-theft high-strength bolt provided by the invention has the beneficial effects that: by arranging the two clamping columns, the sawtooth-shaped clamping teeth at the tail ends of the outer sides of the clamping columns are used for clamping threads on the inner wall of the mounting hole, so that the bolt is effectively prevented from loosening; through the dog that sets up body of rod top, can utilize the dog to plug up regular hexagonal groove to prevent that the external instrument that utilizes from twisting the bolt, it is effectual to prevent burglary.

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 clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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.

When the clamping device is used, the sleeve plate is inserted into the regular hexagonal groove 3 to screw the bolt body 1 into the threaded hole, the rod body 7 is held by a hand to insert the clamping piece 6 into the slot 4, when the clamping piece 6 is completely inserted into the slot 4, the two limiting bolts 11 are screwed out, and the clamping piece 6 is continuously fed into the bottom of the slot 4 by hand; when the clamping piece 6 enters the bottom in the slot 4, under the outward acting force of the two elastic pieces 9, the two clamping columns 10 are pushed into the corresponding through holes 5 by the elastic pieces 9, and the sawtooth-shaped clamping teeth on the outer ends of the clamping columns 10 clamp the threads on the inner wall of the threaded hole, so that the bolt is effectively prevented from loosening.
