Description

Bolt standard part with anti-theft protection performance Technical Field The utility model relates to the technical field of bolts, in particular to a bolt standard part with anti-theft protection performance. Background A bolt is a mechanical part, with a cylindrical threaded fastener of a nut. A fastener consisting of a head part and a screw rod (a cylinder with external threads) needs to be matched with a nut for fastening two parts with through holes. The safety of the bolt-nut fastener in the field infrastructure is important, such as the bolt-nut fastener used in the infrastructure of railway, highway bridge, transmission tower, microwave communication tower, etc. When fixing the article on the fixation clamp, need use bolt and fixation clamp cooperation to fix the article, but the bolt is when using, and the bolt does not possess the theftproof function, and then leads to the bolt to be unscrewed by the lawless persons very easily, causes the condition that article on the fixation clamp was stolen. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a bolt standard part with anti-theft protection performance, which has the advantages of playing an anti-theft function on a bolt and the like, and solves the problem that the bolt does not have the anti-theft function. The bolt standard component with the anti-theft protection performance comprises a bolt rod, a bolt head is arranged at the top of the bolt rod, a disassembly hole is formed in the inner cavity of the bolt head, an anti-theft component is arranged in the inner cavity of the disassembly hole, the anti-theft component comprises a threaded sleeve, the threaded sleeve is arranged in the inner cavity of the disassembly hole, a threaded rod is connected with the inner cavity of the threaded sleeve in a threaded mode, a plum blossom groove is formed in the top of the threaded rod, a spring is arranged at the bottom of the inner cavity of the disassembly hole, one end of the spring is fixedly connected with a top plate, the top of the top plate is contacted with the threaded rod, when the bolt is required to be stolen, a special tool is used for connecting the threaded rod into the threaded sleeve through the plum blossom groove at first, the bottom of the threaded rod is lower than the horizontal plane of the bottom of the threaded sleeve, the threaded rod is extruded through the top plate, the top plate is driven to push the top plate upwards through the inertia of the spring when the rotation of the plum blossom groove is stopped, the threaded rod is more tightly connected with the threaded rod through the top plate, loosening of the threaded rod in the threaded sleeve is avoided, the threaded sleeve is prevented from loosening in the threaded sleeve, the threaded rod, the disassembly hole can be blocked by the threaded sleeve after the threaded rod is installed, a lawless person can be prevented from screwing out, when the threaded rod is required to be screwed out, a special tool is required to be screwed, and the threaded through the threaded rod can be easily removed from the threaded hole by a special bolt through a special wrench.
