Abstract

PURPOSE: A method of coupling a bolt and a nut is provided to maintain a coupled structure safely and continuously. CONSTITUTION: A method of coupling a bolt and a nut is as follows. A structure(2) is fixed by inserting of a bolt(7) into a member(3) and tightening of a nut(4). Thread(6) is formed on one side of the end of the bolt so that the structure has an impact on contraction and expansion due to vibration or temperature, thus the bolt is not separated from the nut. An anti-releasing spring(5) elastically protects the bolt from the thread. The structure is placed between mountains of the bolt to make tight contact with strong frictional force and to make tight contact with one side of the nut with strong frictional force and elasticity so that the nut is not released.

Description

Bolt and nut loosening spring coupling method {omitted}

The present invention relates to a bolt and nut loosening prevention spring coupling method,

Bolts and nuts are widely used to combine mechanical elements in machines and structures, and are excellent in preventing vibration loosening.

The bolt and nut loosening prevention spring combination method

In general, bolts and nuts used as a means of conventional coupling are designed to prevent self-release due to frictional force generated on the mating screw contact surface, but the contact force decreases momentarily when subjected to vibrations and shocks, and the frictional force almost disappears. If this phenomenon is repeated, the screws are loosened and the combined structures and devices are dismantled, which causes a great problem.

The present invention eliminates possible eye elements in order to solve the above-mentioned conventional problems,

This is to provide an excellent bolt and nut loosening spring joining method with the ability to keep the combined structure 2 safely and continuously.

The present invention is a bolt and nut loosening prevention spring coupling method

The bolt body 7 is inserted into the penetrating member 3, and the nut 4 is fixed and fastened. Then, the fixed structure 2 is affected by shrinkage expansion due to vibration or temperature. 4 do not let the puller escape

From the thread (6) formed on one side of the bolt end portion, the anti-loosening blocking spring (5) is inserted and wrapped around the bolt body (7) to be seated on the valley between the acid and the acid of the nut (4) to close the nut with strong friction. The purpose is to provide a bolt and nut loosening prevention spring coupling method that is excellent in the function of safely and continuously holding the combined structure (2) so that (4) does not loosen.

The present invention is a bolt and nut loosening prevention spring coupling method so that the bolt body 7 and the nut (4) does not escape pulley

From the thread 6 formed on one side of the bolt end part, the anti-loosening blocking spring 5 is elastically wrapped and inserted into the bolt body 7 so as to be in close contact with one side of the nut 4 to prevent the nut 4 from loosening.

It has the advantage of providing excellent bolt and nut loosening prevention spring joining method with the ability to keep the combined structure 2 safely and continuously.

In addition, the anti-loosening blocking spring (5) by rotating the steel wire along the valley between the thread (6) and the mountain has the advantage of easy removal.

In addition, the present invention is widely used to couple the mechanical elements to the machine and the structure as a bolt and nut loosening prevention spring coupling method

Providing precise anti-loosening function promotes maximum safety, but it is easy and easy to install, which greatly reduces the construction cost.

In addition, the present invention provides a bolt and nut loosening prevention spring coupling method by providing a bolt and nut loosening prevention spring coupling method

The bolt and nut loosening spring coupling method of the structure has the advantage of providing at the same time

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

"In detail, it looks like this"

The present invention is a bolt and nut loosening prevention spring coupling method

The bolt body 7 is inserted into the member 3 to be penetrated, and the nut 4 is fixed and fastened, and then the fixed structure 2 is moved by vibration or temperature.

In order to prevent the bolt body 7 and the nut 4 from escaping the pulley under the influence of the expansion and contraction, the bolt body 7 is moved from the thread 6 formed on one side of the bolt end portion to the anti-loosening blocking spring 5. Elastically wrapped and inserted

It is placed on the valley between the peak and the peak of the bolt body (7) and closes with strong frictional force. At the same time, one side of the nut (4) is closely attached with strong frictional force and elasticity.

By presenting a method to prevent the nut (4) from loosening, which provides an excellent function to keep the combined structure (2) safely and continuously

Bolt and nut loosening spring combination method

In addition, the thickness of the anti-loosening blocking spring (5) steel wire that is seated on the valley between the thread (6) and the peak of the bolt body (7) is less than the millimeter dimension if the thread (6) is a screw thread of the millimeter dimension

If the thread 6 is an inch dimension, it is provided as an inch or less dimension so that it is firmly and elastically seated on the valley between the mountains.

In addition, the anti-loosening blocking spring (5) steel wire which is seated on the valley between the thread (6) and the peak of the bolt body (7) generates a gap between the nut (4) and the structure (2) during use of the structure (2) Tighten the nut (4) to improve

The anti-loosening blocking spring (5) is rotated along the valley between the thread (6) and the top of the nut (4) so that one side of the nut (4) has a strong elasticity and closes against the loosening function.

In addition, from the thread (6) formed on one side of the bolt end portion of the bolt (7) to prevent the loosening of the bolt body (7) is wrapped around the bolt body (7) is inserted into the valley between the peak of the bolt body (7) and strong It is a method of maximizing the prevention of loosening function by close-off the escape route to come out while the nut (4) is loosened by vibration while making close contact with friction force.

In addition, the present invention is widely used to couple the mechanical elements to the machine and the structure as a bolt and nut loosening prevention spring coupling method

Providing precise anti-loosening function, while achieving maximum safety, construction is simple and easy, and construction cost is greatly reduced.

In addition, the anti-loosening blocking spring (5) by rotating the wire along the valley between the thread (6) and the mountain is easy to attach and detach.

In addition, the present invention by providing a bolt and nut loosening prevention spring coupling method

The product is provided by the bolt and nut loosening spring coupling method, and the structure of bolt and nut loosening spring coupling method is provided at the same time.
