Description

A kind of anti-theft nut structure

Technical field

The utility model relates to nut technical field, specially a kind of anti-theft nut structure.

Background technique

Conventional nut does not have anti-theft function, but in some special use occasions, such as the transmission of electricity of electric system At the field facilities such as steel tower, communication system and highway, for the destruction for preventing criminal, then fastening nut is required to have anti- Steal function.There is miscellaneous antitheft mode in the prior art, for example, nut is designed to can only be by specific purpose tool rotation Special nut, or anti-theft pin etc. is installed in nut, but these anti-theft nuts can be strong by pipe wrench class clamping device System clamps nut and carries out destructive disassembly to nut, and anti-theft performance is poor.

Utility model content

The purpose of this utility model is to provide a kind of anti-theft nut structures, to solve mentioned above in the background art ask Topic.

To achieve the above object, the utility model provides the following technical solutions: a kind of anti-theft nut structure, including nut Set, the nut set is internal to be enclosed with nut, and the top left side of the nut set offers lockhole, is equipped with lock inside the lockhole Core, the lower end of the lock core are welded with the bar positioned at nut set top, are uniformly provided with five first in the middle part of the lock core Groove, the inside of five first grooves are equipped with the first pellet, and the nut, which is put on, to be offered and five the first groove phases Second groove of alignment, second inside grooves are equipped with the second pellet, and the right side of second pellet is equipped with recessed positioned at second Compressed spring inside slot, the lock core are equipped with compatible key therewith.

This setting opens up lockhole on nut set, and can be manually rotated key can link together nut and nut set, And bar can rotate the underface covered to nut, prevent nut from separating with nut set.It must be with key by spiral shell when needing nutting Mother set is separated with nut can just turn nut, play antitheft effect.

Preferably, the top of the nut set offers circular hole, and the diameter of circular hole millimeter smaller than the diameter of nut.

This setting prevents spanner that can be inserted into nut set inside from upper end, carries out nutting operation.

Preferably, the length of first pellet is 8-10 millimeters bigger than the length of the second pellet, and the first pellet and second The diameter of bullet is identical, and the shape of first pellet and the second pellet is cylinder.

Preferably, the size of second groove and the first groove is identical.

Preferably, the shape of the nut set is truncated cone-shaped.

This is arranged so that spanner can not the stuck nut.

Compared with prior art, the utility model has the beneficial effects that this anti-theft nut structure, opens up lock on nut set Hole, can be manually rotated key can link together nut and nut set, and bar can rotate the underface covered to nut, prevent Nut is separated with nut set.It needs to be separated nut set with nut with key when nutting and can just turn nut, play anti- The effect of robber.
