Description
Technical field
This utility model relates to a kind of clamp device, is specifically related to a kind of nut anti-looseness device.
Background technology
The threaded lower fluctuating load that may stand all categories in working order of nuts and bolt, including extremely
Fierce vibration and shock loading.Under the effect of fluctuating load, threaded lost efficacy be typically by himself loosen and
Caused by fatigue rupture.In the ordinary course of things, the life-span of threaded antivibration pine is shorter than the fatigue life of its material and structure
Much, before fatigue rupture, occurred in that because of loosen and cause the threaded inefficacy that gets loose, or occur in that because of
Loosen and cause the premature fatigue of connector and connected piece to be destroyed.Threaded inefficacy can affect the normal of product and equipment
Operating, even can cause serious consequence.
In prior art, the anti-loose method that nuts and bolt assembly is conventional has three kinds: rub locking, mechanical locking and permanent
Locking.Wherein, machinery is locking and friction is locking the most locking, and the most locking non-dismountable the most locking.Commonly use
The most locking have: spot welding, rivet, bonding etc..Permanent anti-loose method is threaded fastener to be destroyed when dismounting, causes nut
Cannot reuse with bolt assembly, cause waste.
Machinery is locking is most commonly used that on bolts and nuts punching, loosens to prevent by locking.This method excellent
Point be locking reliably, its locking reliability is generally dependent on static strength or the fatigue strength of mechanical fixed part.Its shortcoming is to increase
Add the weight being fastenedly connected, manufacture and trouble is installed, it is impossible to carry out motor-driven installation, thus relatively costly.
Common friction is locking is to utilize pad, self-locking nut and double nut etc. to increase friction, and then prevents loosening, but it can
To differ from relative to additive method by property.
Summary of the invention
The purpose of this utility model is to provide a kind of nut anti-looseness device, solves nut anti-looseness device and side in prior art
Method cost height, poor reliability, installation or in-convenience in use defect.
In order to achieve the above object, the technical solution of the utility model is:
A kind of nut anti-looseness device, nuts and bolt threaded after, be close to install on the bolt of nut outer end,
Described nut anti-looseness device includes outer prism clamping coil and interior cylinder lock wire circle, interior cylinder lock wire circle by it,
Head rod and second connecting rod of lower end are connected with the upper and lower termination of outer prism clamping coil, interior cylinder lock wire circle
It is concentrically disposed in outer prism clamping coil central；The coil turn of described outer prism clamping coil is no less than two circles, interior cylinder lock
The few circle of coil turn of the coil ratio of stringing circle outer prism clamping coil；The internal diameter of described interior cylinder lock wire circle is not
More than bolt internal diameter.
Described head rod and the second connecting rod are tangent with the upper and lower end face of interior cylinder lock wire circle respectively.
Described outer prism clamping coil be triangular prism spiral winding, quadrangular spiral winding, pentagonal prism spiral winding, six
Prism spiral winding, the one of eight prism spiral windings.
The coil turn of described outer prism clamping coil is four circles, and the coil turn of interior cylinder lock wire circle is three circles.
Described outer prism clamping coil, interior cylinder lock wire circle, head rod, the second connecting rod are one-body molded.
The beneficial effects of the utility model:
This utility model simple in construction, easy to process, low cost, interior cylinder lock wire circle is tightened on nut outer end, outer rib
Post clamping coil provides lasting pulling force to interior cylinder lock wire circle by head rod, the second connecting rod, it is ensured that interior cylinder
Locking coil and the locking of bolt, and then prevent coming off of nut, it is ensured that the stability that nut uses.
