Nut body apparatus with release prevention structure

Abstract

The invention discloses a nut body device with a loose prevention structure, which is provided with a nut body with inside threads penetrated on a concentric circle relative to a vertical central line, wherein a flat groove structure is formed above the horizontal central line of the nut body and in a position from one side of the nut body to the other side of the nut body beyond the vertical central line of the inside threads. An inclined plane tilting an angle of between 1 degree and 5 degrees relative to the horizontal plane is designed on the bottom surface of the nut body. The nut body device has the same shape as the prior hexagonal nut and can be used singly, and when the nut body device is connected with a bolt, a complicated tool and a procedural fastening method are not needed. The aim of the invention is to provide a nut body device which cannot become loose even affected by additional vibrations and is easy to produce, and to provide a function for preventing falling off.

Description

technical field [0001] The invention relates to a nut body device (METHOD OF FASTENING A NAT AND THEIR FASTENINGSTRUCTURE) with a loosening prevention structure that will not loosen even under severe vibration. Background technique [0002] Structural objects such as automobiles, various machines, electrical equipment, and various buildings are usually fixed with bolts and nuts when they are assembled, because they are easy to assemble and disassemble, and are cheap, so they are widely used. However, when bolts and other fasteners are affected by external forces such as external shocks, vibrations, or heat, the nuts will slowly start to rotate in the opposite direction, losing the fastening force of the bolt fasteners, so that the fastening effect cannot be exerted. effect. [0003] So far, there are still accidents in the industry due to loose bolt and nut bodies. Solving the loosening problem of such bolt and nut fasteners is one of the important issues that the industry...

AI Technical Summary

Problems solved by technology

[0006] However, using the double nut structure requires two nuts, so not only the cost is increased but also the installation has to be repeated twice

[0007] In view of the above-mentioned defects in the existing nuts, the present inventor, based on years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of academic theory, actively researches and innovates, in order to create a new structure with the ability to prevent slack The structure of the nut body device can improve the general existing nuts that are easy to loosen, making it more practical
