Abstract

PURPOSE: An anti-loose beveled nut is provided to assemble a structure with a bolt and prevent loosening against shock and vibration. CONSTITUTION: An anti-loose beveled nut(7) is composed as follows. The top bevel(2) and the bottom bevel(3) have a parallel oblique angle of 0.01~45°. A hole for insertion of a bolt is formed in the center of the beveled nut. The hole has internal threads(1) for coupling with a bolt.

Description

Loosen Nuts for Loosening {omitted}

The present invention is an anti-loosening angle 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 bent nut for preventing the bolt and nut from loosening by vibration in order to join the structure that is not loosened by vibration.

In the present inventors anti-loosening angle nut

The present inventors anti-loosening comb nut 7 is formed with a screw thread 1 inside the central hole of the nut, and the comb angle of the nut upper face comb angle 2 and the lower comb angle 3 forming a parallel diagonal angle of 45 degrees or less at an angle of 0.01 degree or more. Nut 7

In addition, the present inventors anti-loosening comb nut (7) is made of a comb nut (7) to form a parallel oblique angle of less than 45 degrees at an angle of 0.01 degrees or more at the end of the hexagonal, pentagonal, octagonal, square, circular nut tightening tool Provides easy tightening

Combining the structure with the anti-loosening bevel nut 7 of the present invention has the advantage of preventing the bolt and nut from loosening by vibration and to maintain the stability of the structure

In addition, it is easy to manufacture the oblique nut 7 forming a parallel oblique angle of less than 45 degrees at an angle of 0.01 degrees or more, there is an advantage of excellent mass productivity and low manufacturing cost.

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

1 is a perspective view illustrating an anti-loosening bead nut in accordance with the present invention.

The anti-loosening comb nut 7 of the present invention is a comb nut 7 in which the nut upper surface comb angle 2 and the lower comb angle 3 form a parallel diagonal angle of 45 degrees or less at an angle of 0.01 degrees or more.

In addition, when the vibration of the assembled structure is applied to the fastened bevel nut 7, the vibration is transmitted to a part of the area of the anti-loosening bevel nut 7 which forms an oblique angle of less than 45 degrees to an angle of more than 0.01 degrees to impart an impact. Vibration force is transmitted at right angles like a lever is lifted around the bolt shaft (9) at the moment, and it is tightened more strongly by applying a force to the screw thread (1) and the bolt screw thread formed in the inner side of the central hole of the oblique nut (7). This is a bevel nut with a prevention function

In addition, the present inventors anti-loosening comb nut (7) is a hexagonal, pentagonal, octagonal, square, rounded upper comb angle (2) and lower surface comb angle (3) at the nut end of the round angle of 45 degrees or less at an angle of more than 0.01 degrees It is made of comb nut (7) which is made of comb nut to provide easy fastening by using fastening tool.It is an unlocking comb nut that prevents bolts and nuts from loosening due to vibration and keeps the structure stable.

Claims (3)

Anti-loosening comb nut 7 of the present invention is an anti-loosening comb nut 7 characterized in that the nut upper surface comb angle (2) and the lower comb angle (3) are comb-nuts (7) that form a parallel diagonal angle of 45 degrees or less at an angle of 0.01 degree or more. The method of claim 1 When the vibration of the assembled structure is applied to the fastened bevel nut 7, the vibration is transmitted to a part of the area of the anti-loosening bevel nut 7 which forms a parallel diagonal angle of 45 degrees or less at an angle of 0.01 degrees or more and gives an impact. Vibration force is transmitted at right angles, like a lever with a bolt shaft as the center, and applied to the screw thread (1) and the bolt screw thread formed inside the central hole of the oblique nut (7) more tightly coupled to derive an excellent loosening prevention function Anti-loosening bent nut, characterized in that The method of claim 1 The inventors anti-loosening comb nut (7) is a hexagonal, pentagonal, octagonal, square, round the upper comb angle (2) and the lower comb angle (3) to the nut end of the round to form a parallel oblique angle of less than 45 degrees at an angle of 0.01 degrees or more The anti-loosening nut angle nut, which is made of a non-nut nut (7), is provided to be easily fastened using a tightening tool, thereby combining the structure and preventing the bolts and nuts from loosening by vibration and maintaining the stability of the structure.
