Description
The utility model relates to a kind of fastening piece, particularly a kind of dowel formula anti-theft bolt.
At present, bolt and nut is applied on various machines, the equipment etc. widely, and the maintenance of machine, equipment is usually more easily opened these bolt and nuts by instrument for convenience.Yet, when this class bolt and nut is used for electric transmission line connection, communication, mapping and navigation mark etc. and is positioned on open-air iron tower tower material and the metal frame, owing to more easily open these bolt and nuts by instrument, therefore, material is often stolen by the people, causes the massive losses of country.
The purpose of this utility model is to overcome the shortcoming that above-mentioned bolt and nut exists, provide a kind of fastening after the extremely difficult dowel formula anti-theft bolt that withdraws from that unclamps.
The purpose of this utility model is achieved in that the utility model comprises bolt (1), tightening nut (2), anti-theft nut (3) and have the movable latch (4) of spring (5), its special way is to have on the described bolt (1) spacing hole, described anti-theft nut (3) inwall has a hole, a movable latch (4) that has spring (5) is installed in the hole, and described anti-theft nut (3) both can have thread also can not have thread.
To achieve these goals, the utility model comprises bolt (1) equally, tightening nut (2), anti-theft nut (3) and have the movable latch (4) of spring (5), its Placement also can have a hole on described bolt (1), a movable latch (4) that has spring (5) is installed in the hole, and described anti-theft nut inwall has a spacing hole, can have thread also can not have thread.
When using the utility model because movable latch bottom spring can compress, tightening nut has been installed after, set up anti-theft nut again because the obstruction of latch is arranged, the tightening nut of front can't be withdrawed from, thereby plays antitheft effect.
Advantages such as it is simple to the utlity model has manufacturing, and cost is low, and is easy to use can play antitheft effect effectively.
