Abstract

PURPOSE: A nut with an equiangular trapezoidal washer for preventing loosening is provided to enable easy bolt-nut coupling in a structure using a tightening tool and maintain the stability of the structure. CONSTITUTION: A nut(7) comprises threads(1) and a center hole(4) and is attached with a washer. The bevel angle(3) of the bottom of the washer is 0.01~45 degrees. When vibration is applied to the nut, the vibration is transmitted to a wide part of the nut first and the force of the vibration is transmitted to the nut as an eccentric nut.

Description

Nuts with Loosen Isometric Trapezoidal Washers {omitted}

The present invention is an anti-loosening trapezoidal or trapezoidal washer nut.

Bolts and nuts are widely used to couple mechanical elements to machines and structures, and the main role of nuts is to ensure that the bolts and nuts fastened to the joined structure are not loosened.

In general, bolts, nuts and washers used as a means for conventional coupling are designed to prevent self-release due to frictional force generated at the mating contact surface, but when the vibration and shock are applied, the contact pressure decreases instantaneously and the frictional force almost disappears. If this phenomenon is repeated, the nut is loosened and the combined structure and the device are dismantled, which causes a big problem.

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

The present invention is to provide an anti-loosening trapezoidal or trapezoidal washer nut for preventing the bolts and nuts from loosening due to vibration in order to join the structure that is not loosened by vibration.

In the inventor's isometric trapezoidal washer nut, the inventors' anti-loosening trapezoidal or trapezoidal washer nut 7 is a trapezoidal or trapezoidal washer nut with a comb (3) angled at an angle of 45 degrees or less at an angle of 0.01 degrees or more. 7) Provide

By combining the structure with the anti-loosening trapezoidal or trapezoidal washer nut 7 of the present invention, there is an advantage of preventing the bolt and the nut from loosening by vibration and maintaining the stability of the structure.

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

1 is a front view schematically showing a nut with an anti-loosening trapezoidal washer according to the present invention,

The inventors of the present invention anti-loosening trapezoidal trapezoid or trapezoidal washer nut 7 is a trapezoidal or trapezoidal washer nut 7 in which the lower angle of the washer 3 forms an angle of 45 degrees or less at an angle of 0.01 degree or more.

In addition, when the vibration of the assembled structure is applied to the fastened isometric trapezoid or trapezoidal and washer nut 7, the vibration is an unscrewed trapezoidal or trapezoidal washer with an angle of more than 45 degrees and less than 0.01 degrees. The force of the momentary vibration that is transmitted to the area of) and is transmitted to the eccentric load like a lever or trapezoidal washer with a trapezoidal or trapezoidal washer (7) centered on the bolt shaft (9). It is derived from the nut with the trapezoidal washer that is excellent in the function of tightening more strongly by applying the force of close contact with the screw thread (1) formed inside the center hole (4) and the bolt screw thread of 7).

In addition, the present inventors anti-loosening equilateral trapezoidal or trapezoidal washer nut 7 has a hexagonal, pentagonal, octagonal, square, round, washer at the nut end of the butterfly nut, and the comb angle 3 is less than 45 degrees at an angle of 0.01 degrees or more. Made of isometric trapezoidal or trapezoidal washer nuts (7)

It is a nut with an anti-loosening ladder that prevents the bolts and nuts from loosening due to vibrations and keeps the structure stable by easily combining the structure by using the tightening tool.

Claims (3)

The inventors of the present invention anti-loosening trapezoidal trapezoid or trapezoidal washer nut 7 is characterized in that the nut washer is a trapezoidal or trapezoidal washer nut 7 with a comb angle 3 of 45 degrees or less at an angle of 0.01 degree or more. Isometric trapezoidal nuts The method of claim 1 When the vibration of the assembled structure is applied to the fastened isometric trapezoidal or trapezoidal washer nut 7, the vibrations of the anti-loosening trapezoidal or trapezoidal washer nut 7 having an oblique angle of 45 degrees or less at an angle of more than 0.01 degree are included. An anti-loosening equilateral trapezoidal washer nut, characterized in that the force of vibration is transmitted as an eccentric load to the isometric trapezoid or trapezoidal washer nut (7) as if it were first delivered to a large area and then impacted by a momentary bolt axis. The method of claim 1 The inventors of the present inventors anti-angular trapezoidal or trapezoidal nut (7) hexagonal, pentagonal, octagonal, square, round, washer at the nut end of the nut nut, the comb angle (3) is an angle trapezoid of 45 degrees or less at an angle of more than 0.01 degrees Or characterized by being manufactured with a trapezoidal washer nut 7 is within the scope of the claims of the present invention.
