Abstract

PURPOSE: A method of coupling a spring for preventing releasing of a bolt and a nut is provided to maintain a coupled structure(2) safely and continuously. CONSTITUTION: A structure(2) is coupled in a manner that a bolt is inserted into a through hole and a nut(4) tightens. A thread(6) is formed on one surface of the end of the bolt so that the bolt(7) and the nut are not separated due to vibration or temperature. An anti-releasing spring(5) wire elastically protects and inserts the bolt from the thread, is placed between mountains of the bolt, makes tight contact due to strong frictional force, and makes tight contact with one surface of the nut due to strong frictional force and elasticity.

Description

How to combine bolt and nut loosening spring of structure

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

Bolts and nuts are widely used for coupling mechanical elements to machines and structures and are related to the method of coupling bolts and nuts for preventing loosening of structures to perform excellent anti-loosening function.

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 a bolt and nut loosening spring coupling method of the structure excellent in the ability to safely and continuously maintain the combined structure (2).

According to the present invention, the bolt body 7 is inserted into the member 3 through which the bolt and the nut loosening prevention spring are coupled to each other, and the nut 2 is fixed by tightening the nut 4. By the expansion and contraction of the bolt body (7) and the nut (4) does not escape the pulley

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. It is to provide a method of coupling the bolt and nut loosening prevention spring of the structure which is excellent in the function of maintaining the combined structure 2 safely and continuously by suggesting a method so that (4) does not loosen.

The present invention is to prevent the bolt body 7 and the nut (4) is pulled out by the bolt and nut loosening prevention spring coupling method of the structure.

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 is an advantage to provide a bolt and nut loosening spring coupling method of the structure excellent in the ability to safely and continuously maintain the combined structure (2).

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 device and the structure as a bolt and nut loosening spring coupling method of the structure

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 spring coupling product by providing a bolt and nut loosening spring coupling method of the structure

There is an advantage that the bolt and nut loosening spring coupling method of the structure is provided 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"

1 is a perspective view showing a bolt and nut loosening spring coupling method of the structure according to the present invention.

According to the present invention, the bolt body 7 is inserted into the member 3 through which the bolt and the nut loosening prevention spring are coupled to each other, and the nut 2 is fixed by tightening the nut 4. By

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. It is wrapped and inserted resiliently and seated on the valley between the mountain of the bolt body (7) and close contact with strong friction force, and at the same time close contact with one side of the nut (4) with strong friction force and elasticity

It is a method of coupling the bolt and nut loosening prevention spring of the structure that provides a function to prevent the nut (4) from loosening to provide an excellent function to keep the combined structure (2) safely and continuously.

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 anti-loosening function by blocking the escape route to come out while the nut (4) is loosened by vibration while making a 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 method of coupling the bolt and nut loosening prevention spring of the structure

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 of the structure

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.
