Description
Technical field
The invention belongs to anti-loose fastener technical fields, and in particular to a kind of stop nut more particularly to compound embedding spring formula
Stop nut.
Background technique
In numerous areas such as industrial production, automobile, aerospace and rail traffics, screw threads for fastening is largely used in a device
Part realizes connection, but for high-intensitive shock loading and alternating load in the case where, the anti-loose of threaded fastener is asked
Topic is not solved effectively always.
For the anti-loose demand of threaded fastener, existing a large amount of nut, mainly passes through mechanical stop, trimming on the market
The modes such as stop, riveting punching are realized anti-loose, but the effect is unsatisfactory；Nut once loosens, effective connection between screw bolt and nut
Failure can be loosened quickly, and reliability cannot ensure.
In addition, existing nut production and processing difficulty is big, high production cost, yield rate is low and reliability cannot be guaranteed；
In repair and maintenance, some abnormity nuts must be dismantled using specific purpose tool, and disassembly process is cumbersome, time-consuming and laborious, extremely
Inconvenience causes working efficiency low.
Therefore, in this field there are technical problem urgently to be resolved, need to propose more reasonable technical solution, solve with
Upper technical problem.
Summary of the invention
It is an object of that present invention to provide compound embedding spring formula stop nut, which utilizes ripple spring pair
Loading moment allows formation between two sections of screw threads to interfere when the operation power and nut body of nut body and elastic anti-release member screw in,
Tight fit between elastic anti-release member and bolt or screw rod tooth, increases between the thread of nut body and bolt or screw flight
Frictional force achieve the purpose that fastening it is locking.
In order to realize above-mentioned technical effect, the technical scheme adopted by the invention is as follows：
Compound embedding spring formula stop nut, including nut body, are arranged in the elastic anti-release member on nut body.Specifically
It says, along counter sink is axially arranged with, the elastic anti-release member is fixedly installed in counter sink for an end face of the nut body
And elastic anti-release member is equipped with threaded hole, the screwed hole of centre of threaded hole and nut body is coaxial；Elastic anti-release member and nut sheet
It is provided with ripple spring between body, the bottom hole of the lower end in contact counter sink of ripple spring, the upper-end contact elasticity anti-release member of ripple spring
Lower end surface.
Further, elastic anti-release member role is to hold bolt or screw rod, the spiral shell of threaded hole tightly using plastic deformation
Line tooth and bolt or screw flight tooth are fitted close, and increase the friction fastening of threaded connection；It is described to realize this effect
The diameter of thread of threaded hole is greater than or equal to the diameter of thread of screwed hole of centre, and the Major Diam of threaded hole is less than screwed hole of centre
Major Diam.
Further, elastic anti-release member does not contact connection directly with the screwed hole of centre of nut body, when screw rod or bolt
It is easy to appear conflict when cooperating simultaneously with nut body and elastic anti-release member, causes fiting effect poor；Therefore the spiral shell of the threaded hole
Line includes changeover portion and standard paragraphs, and changeover portion is smoothly connected with standard paragraphs, and the screw pitch of changeover portion is greater than the screw pitch of standard paragraphs, standard
The screw pitch of section is equal to the screw pitch of screwed hole of centre；When elastic anti-release member connect cooperation with nut body, changeover portion is located at elasticity
Close to one end of screwed hole of centre in anti-release member, and the lower end surface of elastic anti-release member is started from, standard paragraphs are located in elastic anti-release member
One end far from screwed hole of centre, and terminate in the upper surface of elastic anti-release member.When bolt or screw rod simultaneously with nut body and bullet
Property anti-release member cooperation when, standard paragraphs screw thread is identical as the screw thread of screwed hole of centre, and the screw thread of changeover portion plays the role of linking, makes
Bolt or screw rod more smooth, the good connecting effect when connecting incision.
Further, the screw pitch of changeover portion and standard paragraphs and nut body screwed hole of centre in the threaded hole of elastic anti-release member
Screw pitch it is identical or close, in addition, the screw pitch of changeover portion and standard paragraphs can be used fixed pitch or variation screw pitch design.
Further, the cross section of the elastic anti-release member is polygon, ellipse or other irregular shapes；Described
Counter sink is adapted with the structure of elastic anti-release member.
As a preferred option, the counter sink uses hexagonal counter sink, the screwed hole of centre of hexagonal counter sink and nut
Coaxial arrangement；The cross section of the elasticity anti-release member is corresponding hexagon, and it is locking that the threaded hole of elastic anti-release member is located at elasticity
The center of part.
Further, the lower end surface of the elastic anti-release member is provided with the spring groove of annular, and the upper end of ripple spring is embedded in bullet
In spring slot.Ripple spring is caught in spring groove, is positioned convenient for ripple spring, is played stable support, the elastic force directionality provided is good.
Further, as a preferred solution, at the aperture of the counter sink be equipped with position limiting structure, position limiting structure with
The upper end face contact of elastic anti-release member；The position limiting structure is the flanging bent to the axle center of counter sink being continuously arranged, folding
Axial displacement occurs to outside counter sink for margin elasticity anti-release member.Elastic anti-release member is limited in inside counter sink by position limiting structure,
Make elastic anti-release member axial displacement extreme position be counter sink aperture.
Further, as another preferred scheme, the position limiting structure is the spaced axis to counter sink
The flanging of heart bending, flanging limits, and axial displacement occurs to outside counter sink in elastic anti-release member.Position limiting structure is by elastic anti-release member
Be limited in inside counter sink, make elastic anti-release member axial displacement extreme position be counter sink aperture.
Further, as a preferred solution, the screwed hole of centre of the counter sink and nut body is coaxially set
It sets.
Further, nut body can be used but be not limited to hex nut.
Further, the elastic anti-release member is made of engineering plastics.The plasticity of engineering plastics is strong, is carrying out screw thread
The elastic deformation degree occurred when connection is greater than the generable elastic deformation of metal material, therefore engineering plastics are to screw thread or screw rod
Enclasping force it is stronger, anti-loose ability is more preferable.
Beneficial effects of the present invention are：
1. the present invention, by nut body, elastic anti-release member and ripple spring triplicity, nut body and elastic anti-release member are equal
With screw rod or be bolted, elastic anti-release member holds screw thread or screw rod tightly, plays locking effect, ripple spring provides stable
Axial elastic force, anti-loosing effect are good.
2. the threaded hole setting changeover portion and standard paragraphs of elasticity anti-release member of the invention, in the screw thread and nut body of standard paragraphs
The screw thread of heart threaded hole is identical, and changeover portion is smoothly connected with standard paragraphs, and the screw thread of changeover portion and screwed hole of centre is smoothly postponed,
The connection smooth degree of bolt or screw rod is improved, and introduces bigger active force between two sections of threads.
3. the cross-sectional shape of elastic anti-release member makes elastic anti-release member and nut body convenient for circumferential fixation in the present invention
It keeps in the circumferential relatively fixed.
