Abstract
The utility model discloses an anti-theft bolt which comprises a screw and a nut, wherein, a screw groove is formed at the thread end of the screw along the axial direction, a nut groove is formed on the inner side of the nut along the axial direction, the screw and the nut are mutually occluded and then the screw groove and the nut groove form a pin hole, and a check pin is additionally arranged in the pin hole. The check pin is usually pushed into the pin hole through a hammer and is not easy to be taken out, and the nut is not easy to be disassembled under the condition that the bolt pair is not damaged by a thief, therefore, the anti-theft bolt has good anti-theft performance; and in addition, the utility model also has the advantages of simple structure, convenient installation, and the like.
Description
Technical field
The utility model relates to a kind of mechanical Component, especially a kind of anti-theft bolt.
Background technique
The bolt of prior art is made of the screw rod with screw head, nut.This bolt is very easy to dismounting with spanner.In some machinery,, all need to be connected and fixed by bolt as the pylon of power circuit spanning equipment iron tower, wind-driven generator, communication signal tower etc.Frequent stolen molecule is laid down under the situation that the no one keeps an eye in the open air, causes very serious economy loss easily.For antitheft, on plain bolt, add a cover Anti-theft cap, knock the distortion of screw rod end with iron hammer, but these measures all can not reach real antitheft purpose, the burglar still can dismantle with spanner is powerful.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and is simple in structure, easy for installation, a kind of anti-theft bolt of good anti-theft effect.
The purpose of this utility model is achieved in that a kind of anti-theft bolt, it comprises screw rod and nut, it is characterized in that: screw flutes along axial direction is arranged at the screw flight end, nut groove along axial direction is arranged in the inboard of nut, screw flutes and nut groove constitute a pin hole after the mutual interlock of screw rod and nut, set up a locking pin in this pin hole.
Its cross section of described screw flutes and nut groove all is semicircle, and screw flutes and nut groove constitute a cylindrical pin hole after the mutual interlock of screw rod and nut, set up a cylindrical locking pin in this pin hole.
The utility model is compared its advantage and is with prior art: owing to screw flutes and nut groove after screw rod of the present utility model and the mutual interlock of nut constitute a pin hole, in this pin hole, insert a locking pin, prevent to use spanner to unload lower nut, play antitheft purpose, this structure good anti-theft effect, described locking pin is generally pounded in the pin hole with hammer, and locking pin is not easy to take out, and does not take out pin and can not unload lower nut with spanner.It also has advantages such as simple in structure, easy for installation in addition.
