Equipment, which can not work normally, even causes safety accident.Conventional nut be the nut body equipped with internal screw thread screw hole, completely according to
It is tightened by screw thread and plays fastening effect, with equipment operational shock, the phenomenon that there are nut and bolt loosenesses.How to effectively prevent
Nut loosening reduces the generation of equipment fault, it is ensured that the safe and reliable operation of equipment is the major issue for being badly in need of facing.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of stop nut, this stop nut overcomes conventional nut
The defect only fastened by tightening screw thread, both can effectively prevent nut loosening, and be easy to dismount, it is ensured that threaded fastener is set
Standby normal operation.
In order to solve the above technical problems, it includes concentric knurled nut and eccentric recessed spiral shell that the utility model, which provides a kind of stop nut,
Mother, the threaded hole and nut concentric of the concentric knurled nut are identical as the threaded hole position of conventional nut, described concentric
Knurled nut top is in truncated cone-shaped protrusion, and radius is gradually reduced convex portion from bottom to top, the threaded hole of the recessed nut of bias
With nut decentraction, and rotary table connected in star is arranged at eccentric recessed nut lower part, and the circular platform type groove and nut are concentric, and groove part
Radius is gradually reduced from bottom to top.
Further, the concentric knurled nut is penetrated through with eccentric recessed nut thread hole, and knurled nut and eccentric recessed spiral shell with one heart
Female spiral hole radius is identical, and screw pitch is identical, oppositely oriented.
Further, the concentric knurled nut protruding portion side and nut axis inclination angle are greater than 0 degree, eccentric recessed nut groove
Surface and nut axis inclination angle are greater than 0 degree.
Further, the concentric knurled nut and eccentric recessed nut mounted in pairs, when installation, concentric knurled nut convex portion is stretched
Enter in eccentric recessed nut groove, and knurled nut is installed than eccentric recessed nut closer to joint face with one heart.
Since a kind of stop nut of the utility model uses above-mentioned technical proposal, i.e. this stop nut includes concentric raised spiral shell
Female and eccentric recessed nut, the threaded hole and nut concentric of the concentric knurled nut, the threaded hole position with conventional nut
Identical, the concentric knurled nut top is in truncated cone-shaped protrusion, and radius is gradually reduced convex portion from bottom to top, and the bias is recessed
The threaded hole of nut and nut decentraction, and rotary table connected in star is arranged at eccentric recessed nut lower part, the circular platform type groove and nut are same
The heart, and radius is gradually reduced groove part from bottom to top.The concentric knurled nut is penetrated through with eccentric recessed nut thread hole, and same
Cardiac prominence nut is identical as eccentric recessed nut thread pore radius, and screw pitch is identical, oppositely oriented.The concentric knurled nut convex portion side
Face and nut axis inclination angle are greater than 0 degree, and eccentric recessed nut groove surface and nut axis inclination angle are greater than 0 degree.It is described concentric
Knurled nut and eccentric recessed nut mounted in pairs, when installation, concentric knurled nut convex portion is protruded into eccentric recessed nut groove, and same
Cardiac prominence nut is installed than eccentric recessed nut closer to joint face.This stop nut tightens work on stud by eccentric recessed nut
With making eccentric recessed nut groove side generate extruding to concentric knurled nut protruding portion side, lateral compression effect is formed, effectively
Concentric raised nut loosening is prevented, meanwhile, anti-work of the concentric knurled nut protruding portion side to eccentric recessed nut groove surface
The squeezing action firmly generated prevents eccentric recessed nut loosening, and knurled nut and eccentric recessed nut are oppositely oriented with one heart, effectively anti-
Only concentric knurled nut and eccentric recessed nut loosening.And be easily installed, it dismantles, facilitates mechanical part to overhaul, effectively reduce because of nut
Equipment fault caused by loosening.
