Abstract
The invention discloses a self-locking nut which comprises a nut body. A diamond steel wire lock spring is fixed into a screw hole of the nut body in a tight fit mode. A plurality of partial horizontal folds are arranged on internal threads and external threads of the lock spring respectively. The diamond steel wire lock spring partially provided with the horizontal folds are arranged in the screw hole of the nut body in the close fit mode, so that the friction force between the nut and a bolt is greatly improved, the nut bears balance axial tension force after being screwed down, and the threads bear small axial force. By the adoption of the horizontal folds on the lock spring, the friction force between the nut and the bolt is greatly improved, and the purpose that the nut is fastened in a self-locking mode and can be repeatedly used is achieved.
Description
Technical field:
The present invention relates to nut, reusable self-locking nut when particularly one is applicable to machine-building.
Background technique:
Existing self-locking nut, is be provided with a screw at the center of a nut, is provided with nylon material or the screw thread of screw mouth is made certain amount of deformation, make to produce higher resistance between nut and screw rod, realize self-locking at screw mouth; Some self-locking nuts are that the angle of thread root is changed, and are used for reducing axial tension, increase frictional force and reach self-locking.Because nut and screw thread thereof are integral materials, nut its first button screw thread and second mouthful of screw thread after tightening bear the axial tension of 70-80%, easily cause distortion, the stripped thread of the first button and the second button screw thread, fall button, cause nut to scrap.Existing self-locking nut is all a kind of disposable products, can not reuse, and makes troubles and waste to user.
Summary of the invention:
The object of this invention is to provide one not easily produce stripped thread, dropout and loosen, repeatedly used self-locking nut.
Technological scheme of the present invention completes as follows, a kind of self-locking nut, and it comprises a nut, it is characterized in that: be tightly fixed a diamond wire snap in the screw of nut.
The internal and external threads of snap is respectively equipped with the cross break of multiple local.
There is the diamond wire snap of cross break the present invention close-fitting unification local in the screw of nut, considerably increase the frictional force between nut and bolt, there is the axial tension equilibrium of tightening consequence and being subject to, suffered by screw thread, axial force is less, add the many places cross break on snap, considerably increase the frictional force between nut and bolt, realize self-locking fastening, repeatedly used object.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment:
Describe embodiment in detail by reference to the accompanying drawings, it comprises a nut 1, and be tightly fixed a diamond wire snap 3 in the screw 2 of nut.In order to increase internal and external threads and bolt and nut on snap screw thread between frictional force, the internal and external threads of snap is respectively equipped with multiple local cross break 4.The present invention is because be tightly fixed in the screw of nut by diamond wire snap, its whole screw thread evenly can share load, each screw thread average force is less, so not easily produce stripped thread, dropout, loosen etc. phenomenon, cross break on diamond wire snap further increases the frictional force between screw thread, self-locking effect is more firm, due to snap elastic reaction, the stubborn power not only produced is large, and can repeatedly dismantle, Long-Time Service, can extensively with for fields such as space flight, aviation, military project, automobile, boats and ships, electrical equipment, machine-building.
Claims (2)
1. a self-locking nut, it comprises a nut, it is characterized in that: be tightly fixed a diamond wire snap in the screw of nut.
2. a kind of self-locking nut according to claim 1, is characterized in that: on the internal and external threads of snap, be respectively equipped with the cross break of multiple local.
