Problems solved by technology

[0002] In the prior art, most of the parts on some machine equipment are connected by bolts, but the machine will vibrate during operation, and the bolts on some parts will automatically loosen
The existing protective measures include anti-loosening by bonding and anti-loosening with spring gaskets. Most of the threaded fasteners will be destroyed when the anti-loosening by bonding is disassembled and cannot be reused.

Embodiment Construction

[0005] Screw the T-shaped bolt 1 in the clockwise direction on the screw hole of the machine part 4, set the C-shaped gasket 2 on the bolt, the gasket is made of spring steel, and the end 3 of the gasket pointing to the counterclockwise direction opens outwards. Serrations are provided on the surface of the gasket and the bottom surface of the head of the bolt respectively and engage with each other 6 . Serrations 5 are provided on the periphery of the screw hole outer end of the machine part, the tooth tips of the serrations face the direction of the screw hole, and the slopes of the serrations face the counterclockwise direction. The serrations on the face of the washer lock the head of the bolt, and the open end of the washer catches the serrations on the outer end of the screw hole. The elastic C-shaped gasket on the bolt can only rotate clockwise. When it rotates counterclockwise, the opened end of the C-shaped gasket will be stuck on the serrations at the outer end of th...

Abstract

The invention discloses a permanent lock bolt, wherein a C-shaped gasket is arranged on a T-shaped bolt in a sleeving manner; the gasket is made of a spring steel material; the surface of the gasket is provided with saw teeth; one end of the gasket is opened towards the outside of a circle. Saw teeth are arranged in the edge of the bottom surface of the head part of the T-shaped bolt and are mutually meshed with the saw teeth in the gasket; the periphery of the outer end of a bolt hole of a machine member is provided with saw teeth with tooth tips facing the direction of the bolt hole; the inclined surfaces of the saw teeth of the bolt hole face the anticlockwise direction; the bolt can be only rotated in the clockwise direction in the bolt hole of the machine member; when the bolt is rotated in the anticlockwise direction, one end, which is opened outwards, of the C-shaped gasket is jammed on the saw teeth of the machine member. Therefore, the purpose of the lock bolt is achieved.

Description

technical field [0001] The invention relates to a permanent anti-loosening bolt and its application method. Background technique [0002] In the prior art, most of the parts on some machine equipment are connected by bolts, but the machine will vibrate during operation, and the bolts on some parts will automatically loosen. Existing protective measures include bonding anti-loosening and adding spring gaskets to prevent loosening. Most of the adhesive anti-loosening will destroy threaded fasteners during disassembly and cannot be reused. Spring gaskets are added to prevent loosening, because the spring gaskets will be deformed under long-term pressure and lose the anti-loosening effect. In order to solve the above problems, the object of the present invention is to provide a permanent anti-loosening bolt, which can effectively prevent the bolt from loosening. Contents of the invention [0003] The invention is realized in the following way: serrations are provided on the ...
