Compared with the prior art, the internal thread of the nut (3) adopts a 30-degree wedge-shaped inclined plane (1), and a helicoid (2) is screwed on the nut body (3).

2. The anti-loose and anti-drop nut as claimed in claim 1, wherein: the inner side of the nut (3) is provided with a thread; and a boss is arranged above the nut (3), and threads meshed with the inner side of the nut (3) are arranged on the outer edge of the boss.

3. The anti-loose and anti-drop nut as claimed in claim 1, wherein: the included angle between the wedge-shaped inclined plane (1) and the thread is 30 degrees.

Technical Field

The invention relates to the technical field of machinery, in particular to a locking and anti-falling nut.

Background

With the development of the times, the anti-loosening screw thread adopted for loosening prevention cannot meet the actual requirements, and particularly in the assembly of parts with high fastening requirements, the conventional anti-loosening screw thread cannot meet the requirements, so that an anti-loosening and anti-loosening nut with high fastening capability and low production cost needs to be designed.

Disclosure of Invention

The invention is intended to solve the technical problem in mechanical technology at least to a certain extent. Therefore, the invention provides an anti-loose and anti-drop nut.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides a locking anticreep nut includes 30 wedge inclined planes, helicoidal and nut, and the nut internal thread is equipped with 30 wedge inclined planes, has the helicoidal on the nut. Compared with the prior art, the internal thread of the nut adopts a 30-degree wedge-shaped inclined plane, and a helicoid is screwed on the nut body.

Preferably, the inner side of the nut is provided with threads; a boss is arranged above the nut, and threads meshed with the inner side of the nut are arranged on the outer edge of the boss.

Preferably, the included angle between the wedge-shaped inclined plane and the thread is 30 degrees.

The invention has the beneficial effects that: by adopting the structure, compared with the prior art, the nut structure has the advantages; the nut has strong wear resistance and shear resistance, the inclined surface of the nut thread can ensure that the locking force of the nut is uniformly distributed on the threads of all the teeth, and the pressing force on the thread surface of each tooth is uniformly distributed, so the nut can better solve the problems of thread wear and shear deformation. The repeated use performance is good, and locknut through fastening and dismantling many times repeatedly, its locking force still does not reduce, can keep original locking effect. The anti-loosening nut has excellent anti-vibration performance, when the threads are screwed down, the thread linearity of the crest of the bolt tightly enters the wedge-shaped inclined plane of the nut to be clamped, the normal acting force generated when the anti-loosening nut is fastened is far greater than that of a common standard nut, and the anti-loosening nut has great anti-loosening capacity.
