Description
【Technical field】
The technical field of fastener is the utility model is related to, particularly a kind of technical field of anti-loose anti-theft nut.
【Background technology】
Fastener products the most frequently used in electromechanical industries are traditional hexagonal (hexagon)nut at present, due to the nut body of hexagonal (hexagon)nut
For hexagon, as long as using general tool with regard to that can turn.Therefore often occur in various plant equipment, electric power facility split
Unload, steal phenomenon, immeasurable loss is caused to collective, country.
Because nut is when fastening latter stage, the surface of nut and fixation rubs, and easily causes by fixation surface
It is impaired, and tighten laborious.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of anti-loose anti-theft nut, and use is general
Logical instrument can not turn, and can avoid fixation surface damage, tighten laborsaving.
To achieve the above object, the utility model proposes a kind of anti-loose anti-theft nut, including body, groove, nut body,
Screw, caulking part and locking pad, the body are truncated cone-shaped shape, and one end of the body is provided with groove, set in the groove
There is nut body, the nut body is the isosceles triangle shape that three angles change into arc-shaped, and the screw runs through body and spiral shell
Parent, the other end of the body are provided with caulking part, and the body is rotatably connected by caulking part and locking pad, described locking
Pad and be provided with the arc convex of ring-type, front end face and the locking pad of the locking pad for coniform shape, the rear end of the locking pad
Medial surface between set transition circle cambered surface.
Preferably, the medial surface of the locking pad is provided with overcoat.
Preferably, the body and nut body by integral forming.
The beneficial effects of the utility model：The utility model is provided with groove by one end of body, and nut is provided with groove
Body, nut body are the isosceles triangle shape that at least one angle changes into arc-shaped, can not be turned using common instrument, cone
The locking pad of shape can play anti-pine certainly after being driven plain, the rear end of locking pad is provided with the arc convex of ring-type, can reduce locking pad
Frictional force between body, during tightening operation, the rotation probability of locking pad can be reduced, reduce fixation surface damage machine
Rate, and tighten laborsaving；Transition circle cambered surface, the inner side of locking pad are set between the medial surface of the front end face of locking pad and locking pad
Face is provided with overcoat, is further ensured that fixation surface is not damaged.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of structural representation of anti-loose anti-theft nut of the utility model；
Fig. 2 is the structural representation that locking pad is arranged on body.
In figure：The locking pad of 1- bodies, 2- grooves, 3- nut bodies, 4- screws, 5- caulking parts, 6-, 61- arc convex, 62-
Transition circle cambered surface, 63- overcoats.
【Embodiment】
Refering to Fig. 1,2, a kind of anti-loose anti-theft nut of the utility model, including body 1, groove 2, nut body 3, screw 4, riveting
Socket part 5 and locking pad 6, the body 1 are truncated cone-shaped shape, and one end of the body 1 is provided with groove 2, is provided with the groove 2
Nut body 3, the nut body 3 are the isosceles triangle shape that three angles change into arc-shaped, and the screw 4 runs through the He of body 1
Nut body 3, the other end of the body 1 are provided with caulking part 5, and the body 1 is rotatably connected by caulking part 5 and locking pad 6,
The locking pad 6 is coniform shape, arc convex 61 of the rear end provided with ring-type of the locking pad 6, before the locking pad 6
Transition circle cambered surface 62 is set between the medial surface of end face and locking pad 6, and the medial surface of the locking pad 6 is provided with overcoat 63, institute
Body 1 is stated to be integrally formed with nut body 3.
Utility model works process：
A kind of anti-loose anti-theft nut of the utility model is provided with groove 2, groove 2 in the course of the work, by one end of body 1
Interior to be provided with nut body 3, nut body 3 is the isosceles triangle shape that at least one angle changes into arc-shaped, using common instrument without
Method turns, and the locking pad 6 of coniform shape can play anti-from pine after being driven plain, the arc that the rear end of locking pad 6 is provided with ring-type is convex
Rise, can reduce the frictional force between locking pad 6 and body 1, during tightening operation, the rotation probability of locking pad 6 can be reduced, reduce quilt
Fixture surface damage probability, and tighten laborsaving；Transition is set between the front end face of locking pad 6 and the medial surface of locking pad 6
Arc surface 62, the medial surface of locking pad 6 are provided with overcoat 63, are further ensured that fixation surface is not damaged, with prior art
Compare, can not be turned using common instrument, and fixation surface damage can be avoided, tighten laborsaving.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to the scope of protection of the utility model.
