Embodiment 1

[0014] The present embodiment provides a kind of anti-loosening mechanical device, it is characterized in that: described anti-loosening mechanical device comprises nut 1, sawtooth 2, flange pad 3, triangular tooth 4;

[0015] Among them: the outside of the nut 1 is hexagonal, the inside is provided with threads, and the bottom is provided with serrations 2. The serrations 2 provided at the bottom of the nut 1 correspond to the serrations 2 connected to the flange pad 3. The flange pad 3 is disc-shaped, and the center is provided with a Round hole, the upper part corresponds to the sawtooth 2 at the bottom of the nut 1. The bottom of the flange pad 3 is also provided with a triangular tooth 4. The helical tooth surface of the nut 1 of the present invention and the helical tooth surface of the flange pad 3 can only rotate forward , lock each other when rotating in reverse.

[0016] Said sawtooth 2 is provided correspondingly to the sawtooth 2 , and the direction of rotation of ...

Abstract

An anti-loose mechanical device is characterized by comprising a nut, sawteeth, a flange gasket and triangular teeth. The outer portion of the nut is hexagonal, and threads are arranged inside the nut; the sawteeth are arranged at the bottom of the nut, and the sawteeth arranged at the bottom of the nut are correspondingly connected with the sawteeth on the flange gasket; the flange gasket is in a disc shape, and a round hole is formed in the center of the flange gasket; the sawteeth are arranged on the upper portion, corresponding to the sawteeth at the bottom of the nut, of the flange gasket; and the triangular teeth are arranged at the bottom of the flange gasket. The helical tooth face of the nut and the helical tooth face of the flange gasket can only rotate in the forward direction, and when the helical tooth face of the nut and the helical tooth face of the flange gasket rotate inversely, the helical tooth face of the nut and the helical tooth face of the flange gasket are locked mutually. The anti-loose mechanical device has the advantages of being good in anti-loose antitheft effect, simple in design, easy to manufacture and low in cost.

Description

technical field [0001] The invention relates to the field of an anti-loosening and anti-theft fastening mechanical device, and in particular provides an anti-loosening mechanical device. Background technique [0002] The existing anti-theft nuts are mainly divided into three categories, one is that it is inconvenient to install and use with special tools; the other is that the appearance is standard but the structure is complicated, and the production is difficult; the third is that the structure of the anti-theft and anti-loosening nuts is too complicated, which is not conducive to popularization use. As time goes by, the screws of the steel structure will loosen under the action of external force. This is a relatively prominent shortcoming of torsional shear bolts. Contents of the invention [0003] The object of the present invention is to solve the problem of the anti-theft and anti-loosening nut which is too complex in structure, which is not conducive to populariza...
