The utility model discloses an insertion-type anti-loose nut which comprises a nut main body, wherein one end of the nut main body is provided with a spring lock parent body, the middle parts of the spring lock parent body and the nut main body are provided with through threaded holes, the side edge of the spring lock parent body is provided with a spring lock hanging lug, and the nut main body, the spring lock parent body and the spring lock hanging lug are integrally formed. The opposite side distance of the nut body is 19mm, the spring lock parent body is arranged in a circular ring shape, and the outer diameter of the spring lock parent body is 15 mm. The height of the nut body is 9.36mm, and the height of the nut body and the spring lock parent body is 11.7 mm. The utility model relates to a spring lock hanging lug and a spring lock parent body which clamp threads on a bolt and lift from a nut main body, and isolate a spring lock part from the load of the nut main body so as to prevent falling off caused by vibration. The insert-type locknut is commonly used for high vibration tables and vibration equipment. The strength of the bolt should match the strength of the nut body to prevent damage to the threads of the threaded hole. They are suitable for fastening most machines and equipment at comparable strength levels to 8.8 bolts.

Description

Plug-in type locknut

Technical Field

The utility model relates to the technical field of locknuts, in particular to an insertion type locknut.

Background

Locknut uses usually on high shaking table and vibration equipment, and current locknut's structure is complicated, and its locking effect when with the bolt spiro union is not good, is unfavorable for its fastening most machinery and equipment. To this end, we propose a plug-in locknut.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a plug-in type locknut to solve the above problems of the prior art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a bayonet lock nut, includes the nut main part, the one end of nut main part is equipped with the lock latch parent, the middle part of lock latch parent and nut main part is equipped with the screw hole that runs through, lock latch parent side is equipped with the lock latch hangers, nut main part, lock latch parent and lock latch hangers set up as integrated into one piece. The opposite side distance of the nut body is 19mm, the spring lock parent body is arranged in a circular ring shape, and the outer diameter of the spring lock parent body is 15 mm. The height of nut main part is 9.36mm, the height of nut main part and lock parent is 11.7 mm.

Compared with the prior art, the utility model has the beneficial effects that: the steel spring lock hanging part (namely the spring lock hanging lug and the spring lock parent) clamps the screw thread on the bolt and lifts from the nut main body, and the spring lock part is isolated from the load of the nut main body so as to prevent the falling caused by vibration. The insert-type locknut is commonly used for high vibration tables and vibration equipment. The strength of the bolt should match the strength of the nut body to prevent damage to the threads of the threaded hole. They are suitable for fastening most machines and equipment at comparable strength levels to 8.8 bolts.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a bayonet lock nut, includes nut main part 4, the one end of nut main part 4 is equipped with lock latch parent 2, the middle part of lock latch parent 2 and nut main part 4 is equipped with screw hole 3 that runs through, 2 sides of lock latch parent are equipped with lock latch hangers 1, nut main part 4, lock latch parent 2 and lock latch hangers 1 set up for integrated into one piece.

Locknuts, self-tightening nuts, are a common type of fastening locknut. Including mechanical anti-loosening, rivet-punch anti-loosening, friction anti-loosening, structural anti-loosening and the like. The locknut is a nut, is screwed together with a bolt or a screw rod to play a role in fastening, is an original piece which must be used by all production and manufacturing machines, is a part for tightly connecting mechanical equipment, and can be connected together through an inner thread, the locknut with the same specification and the screw.

The locknut has three advantages:

first, superior vibration resistance: when the screw is screwed, the thread linearity of the crest of the bolt tightly enters the 30-degree wedge-shaped inclined plane of the nut to be clamped, and the normal acting force generated by applying to the wedge-shaped inclined plane forms a 60-degree included angle with the axis of the bolt instead of the 30-degree included angle, so that the normal acting force generated by fastening the locknut is far greater than that of a common standard nut, and the locknut has great looseness-proof and vibration-proof capabilities.

Secondly, the wear and shear resistance is strong: the 30-degree inclined plane at the bottom of the nut thread enables the nut locking force to be uniformly distributed on all threads of all the teeth, and the pressing force on the thread surfaces of all the teeth is uniformly distributed, so that the nut can better solve the problems of thread abrasion and shearing deformation.

Thirdly, the repeated use performance is good: a large number of uses show that locknut through fastening and dismantling many times repeatedly, its locking force still does not reduce, can keep original locking effect.

The opposite side distance of the nut body 4 is 19mm, the lock cylinder body 2 is arranged in a circular ring shape, and the outer diameter of the lock cylinder body 2 is 15 mm. The height of the nut body 4 is 9.36mm, and the height of the nut body 4 and the height of the lock parent body 2 are 11.7 mm.

Specifically, during installation, the steel latch hanging part (i.e., the latch hanging lug 1 and the latch parent body 2) clamps the thread on the bolt and lifts from the nut body 4, so as to isolate the latch part from the load of the nut body 4 and prevent the falling caused by vibration. The insert-type locknut is commonly used for high vibration tables and vibration equipment. The strength of the bolt should be matched to the strength of the nut body 4 to prevent damage to the threads of the threaded bore 3. They are suitable for fastening most machines and equipment at comparable strength levels to 8.8 bolts.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
