Abstract
The invention relates to the technical field of machinery, in particular to an anti-loose and anti-drop nut which comprises a 30-degree wedge-shaped inclined plane, a helicoid and a nut body. The internal thread of nut body is equipped with 30 wedge inclined planes, has the helicoidal on the nut body. Compared with the prior art, the internal thread of the nut body adopts a 30-degree wedge-shaped inclined plane, and the nut body is screwed with a helicoid, so that the defect of free falling caused by operation or improper installation torque is reduced, and the anti-loosening and anti-falling functions of the nut are ensured.
Description
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.
Drawings
FIG. 1 is a schematic structural view of the anti-loose and anti-drop nut of the invention:
1 is a wedge-shaped inclined plane, 2 is a spiral ring, and 3 is a nut.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
The invention discloses an anti-loose and anti-drop nut which comprises a 30-degree wedge-shaped inclined surface 1, a helicoid 2 and a nut 3, wherein the 30-degree wedge-shaped inclined surface 1 is arranged on an internal thread of the nut 3, and the helicoid 2 is arranged on the nut 3. Compared with the prior art, the internal thread of the nut 3 adopts a 30-degree wedge-shaped inclined plane 1, and the nut body 3 is screwed with a helicoid 2.
The inner side of the nut 3 is provided with threads; 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.
The included angle between the wedge-shaped inclined plane 1 and the thread is 30 degrees.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
