Abstract
It the utility model is related to a kind of anti-loose lock nut, category mechanical engineering Element Technology field.The utility model includes stop nut, clamping nut, stop nut is screwed on bolt, clamping nut is screwed on stop nut again, tighten the end face that clamping nut makes its endoporus compression boss push down stop nut, the internal bore groove and peripheral groove for making stop nut are deformed, and then the main threaded section of stop nut and secondary threaded section is set axially to produce relative deformation and relative skew, so that thread faces different with bolt contact and locked respectively for the main threaded section and secondary threaded section of stop nut, locking anti-loose effect is played.
Description
Technical field
It the utility model is related to a kind of anti-loose lock nut, category mechanical engineering Element Technology field.
Background technology
Stop nut be it is a kind of prevent occurring the fastener loosened in use, stop nut and bolt or screw rod are screwed in one
Rise and reach fastening effect, anti-loose method has that machinery is locking, riveting rushes that locking and friction is locking etc., and it is most widely used anti-that friction is locking
Loose measure method, itself the frictional force that nut can be prevented to relatively rotate is produced by the way that locking nut is secondary, reach locking purpose, it is existing
Problem is that most of locking nuts are flanks by holding bolt tightly, using increasing rubbing for nut thread face and bolt thread face
Power is wiped to prevent nut from being rotated relative to bolt, reaches anti-loose effect.But frictional force is unstable, easy locking failure.
The content of the invention
The utility model purpose is to provide a kind of anti-loose lock nut, and the thread for making stop nut by clamping nut exists
Axial deformation so that the pitch of nut thread is different from the pitch of bolt thread, causes nut " to suppress on bolt and turn motionless ",
Play and prevent nut from being produced relative rotation with bolt, so as to reach locking purpose, for solving the locking problem of nut.
The technical solution adopted in the utility model is：A kind of anti-loose lock nut, including stop nut 1, clamping nut 2,
The stop nut 1 includes inner hole thread I3, outer round thread 4, peripheral groove 5, internal bore groove 6, end face 7, and inner hole thread I 3 is divided into again
Main threaded section 8 and secondary threaded section 9, the clamping nut 2 include inner hole thread II 10, endoporus compression boss 11；The locking spiral shell
Mother 1 is screwed on bolt by inner hole thread I3 connections, then clamping nut 2 is passed through its inner hole thread II10 and stop nut 1
The outer connection of round thread 4 is screwed on stop nut 1, and tightening clamping nut 2 makes its endoporus compression boss 11 tightly push down stop nut 1
End face 7, make stop nut 1 peripheral groove 5 and internal bore groove 6 axially be deformed so that the main threaded section 8 of stop nut 1
Thread faces different with bolt contact and locked respectively with secondary threaded section 9.
Operation principle of the present utility model is：Stop nut 1 is screwed on bolt by inner hole thread I3 connections, then pressure
Tight nut 2 is connected by its inner hole thread II10 with the outer round thread 4 of stop nut 1 to be screwed on stop nut 1, tightens compression spiral shell
Cap 2 makes its endoporus compression boss 11 tightly push down the end face 7 of stop nut 1, and the peripheral groove 5 and internal bore groove 6 for making stop nut 1 exist
Axially it is deformed so that thread faces different with bolt contact simultaneously the main threaded section 8 and secondary threaded section 9 of stop nut 1 respectively
Locking, reach the locking purpose of locking.
The beneficial effects of the utility model are：Make the main threaded section 8 of stop nut 1 and secondary spiral shell by tightening clamping nut 2
Tooth section 9 is axially being deformed changing with pitch, has the function that the thread of left and right fishbolt, plays locking anti-loosing effect.

Embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail, but content of the present utility model is not
It is limited to the scope.
Embodiment 1：As Figure 1-4, a kind of anti-loose lock nut, including stop nut 1, clamping nut 2, it is described locking
Nut 1 is characterised by including inner hole thread I3, outer round thread 4, peripheral groove 5, internal bore groove 6 and end face 7, and inner hole thread I3 is divided into again
Main threaded section 8 and secondary threaded section 9, the clamping nut 2 are characterised by including inner hole thread II10, endoporus compression boss 11.
Stop nut 1 is screwed on bolt by inner hole thread I3 connections, then clamping nut 2 is passed through its inner hole thread II10 and locking spiral shell
The connection of outer round thread 4 of mother 1 is screwed on stop nut 1, and tightening clamping nut 2, its endoporus compression boss 11 is tightly pushed down locking
The end face 7 of nut 1, the peripheral groove 5 and internal bore groove 6 for making stop nut 1 are deformed axially, made by tightening clamping nut 2
The main threaded section 8 and secondary threaded section 9 of stop nut 1 are axially being deformed changing with pitch so that the main thread of stop nut 1
Thread faces different with bolt contact and locked respectively for section 8 and secondary threaded section 9, play locking anti-loosing effect.
Specific embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not
It is limited to above-mentioned embodiment, in those of ordinary skill in the art's possessed knowledge, this practicality can also be not being departed from
Various changes can be made on the premise of new objective.
