Description
Technical field
The present invention relates to a kind of nut, more particularly to a kind of seperated auto-lock stop nut.
Background technology
The bolt assembly that the fastener of usual mechanical equipment thread connection is made of bolt, nut, spring washer etc., one
As in the case of bolt by nut itself it is locking.Wherein stop nut is mainly the following：The i.e. built-in anti-slow ring type of nylon
Stop nut, built-in anti-slow steel-sheet type stop nut, built-in anti-slow coil spring formula stop nut, built-in anti-slow pin (ball) formula are locking
Nut changes form of thread angie type stop nut, opens anti-slow slot type stop nut in sagittal plane, screw thread is rushed deformation to increase spiral shell
Female and bolt moment of friction formula stop nut etc..In addition, nut is realized using the joint retention device formed from external action
Locking has：Add spring washer locking, add locked spacer locking, it is locking using adhesive, in bolt, the punching deformation of nut junction
Put the forms such as locking.More than anti-loose method, cuts both ways, but in operating modes such as vibration frequency is high, oscillation intensity is big, vibration period length
Under, it is difficult to meet locking requirement.And nut currently used in the market under vibration environment pretightning force decline cause connection loosen,
It cannot play and be fastenedly connected, be particularly easy to trigger failure and accident.
The content of the invention
The purpose of the present invention is that solve the above-mentioned problems and provides a kind of seperated auto-lock stop nut, solves
Nut pretightning force decline under vibration environment leads to problems such as connection loosen, cannot play and be fastenedly connected.
To solve the above-mentioned problems, the present invention provides a kind of technical solutions：A kind of seperated auto-lock stop nut, wound
New point is：Including recessed nut main body, recessed nut thread hole, recessed nut groove, knurled nut main body, knurled nut threaded hole and convex spiral shell
Female boss；The recessed nut main body middle position is equipped with recessed nut thread hole；The recessed nut groove is located at recessed nut main body bottom
Portion middle position；The knurled nut main body middle position is equipped with knurled nut threaded hole；The knurled nut boss is located at knurled nut master
At the top of body；The recessed nut main body is located at the positive upside of knurled nut main body.
Preferably, the recessed nut groove side is equipped with taper.
Preferably, the knurled nut boss center line deviates knurled nut screw thread centerline hole.
Preferably, the knurled nut boss side surfaces are equipped with taper.
Preferably, the recessed nut groove is identical with the knurled nut boss side surfaces taper.
Preferably, the recessed nut thread hole and the threaded hole that knurled nut threaded hole is same specification.
Preferably, the knurled nut boss top maximum is while less than recessed nut groove bottom maximum.
Beneficial effects of the present invention：
(1) present invention have it is rational in infrastructure it is simple, production cost is low, easy for installation, self locking anti-loose nut is set, ensures shaking
Pretightning force, which will not fail, under rotating ring border causes connection to loosen, so as to reduce the generation for triggering failure and accident.
(2) present invention sets knurled nut boss center line to deviate knurled nut screw thread centerline hole, to attachment bolt during use
Radial pressure is generated, forms radially locking moment of friction.
(3) present invention sets recessed nut groove identical with the knurled nut boss side surfaces taper, ensure that matching somebody with somebody during connection
Conjunction and stability.
