Abstract
The utility model discloses a kind of Anti-loosening nuts, it include: that stud 1, opening nut 2 and double cut nut 3 form, the stud is equipped with stud screw thread 101, it is open in nut equipped with straight thread 201 and oblique screw thread 202, the double cut nut is equipped with internal screw thread 301 and external screw thread 302, the stud screw thread is matched with straight thread, and oblique screw thread is matched with external screw thread, and straight thread is matched with internal screw thread；Gap 303 is additionally provided on the double cut nut.It is designed by special structure, realizes the technical effect of nut anti-looseness.
Description
Technical field
The present invention relates to nut field more particularly to Anti-loosening nuts.
Background technique
Stop nut, self-tightening nut are a kind of common fastening locknuts.For stop nut originating from foreign countries, it is with spy
Different engineering plastics are permanent to be attached on screw thread, makes internal and external threads in the process that tightens, and engineering plastics are extruded and generate powerful
Reaction force, substantially increase the frictional force between internal and external threads, provide the absolute resistance to vibration.
Utility model content
The purpose of the utility model is to provide a kind of stop nuts, are designed by special structure, realize nut anti-looseness
Technical effect.
To solve the above problems, the utility model discloses a kind of Anti-loosening nuts, comprising: stud, opening nut and
Double cut nut composition, the stud are equipped with stud screw thread, are equipped with straight thread and oblique screw thread, the double cut nut in opening nut
Be equipped with internal screw thread and external screw thread, the stud screw thread matches with straight thread, and oblique screw thread is matched with external screw thread, straight thread and
Internal screw thread matches；Gap is additionally provided on the double cut nut.
Further, wherein the height of the straight thread is the 1/2 of opening nut.
Further, wherein the height in the gap is the 1/2 of double cut nut.
Further, wherein double cut nut top is additionally provided with vertical non-threaded area.
The utility model has the beneficial effects that:
First, superior resistance to shock: the normal force that stop nut generates when fastening is much larger than common standard nut,
With great loose-proof anti-vibration ability.
Second, wear-resistant and anti-shear ability is strong: nut can preferably solve the problems, such as thread abrasion and shear-deformable.
Third, repeat performance are good: by the setting stop nut in gap by repeatedly fastening and dismantling repeatedly, lock
Clamp force does not reduce still, is able to maintain original locking effect.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described.
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the use figure of the utility model.
Specific embodiment

Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Obviously, it is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Embodiment one:
A kind of Anti-loosening nut, comprising: stud 1, opening nut 2 and double cut nut 3 form, and the stud is equipped with spiral shell
Male screw 101, the nut that is open is interior to be equipped with straight thread 201 and oblique screw thread 202, and the double cut nut is equipped with internal screw thread 301 and outside
Screw thread 302, the stud screw thread are matched with straight thread, and oblique screw thread is matched with external screw thread, and straight thread is matched with internal screw thread；
Gap 303 is additionally provided on the double cut nut.
Wherein the height of the straight thread is the 1/2 of opening nut.Wherein the height in the gap is the 1/ of double cut nut
2.Double cut nut top is additionally provided with vertical non-threaded area 304.
Opening nut is screwed in stud any position when use, then double cut nut is screwed on stud, makes double cut nut
External screw thread is tiltedly threadedly engaged with opening nut, and by further tightening, gap is compressed, sufficiently realizes anti-loosening effect
Fruit.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
