Summary of information:We have more than ten years of experience in screw industry production, the main products are: iron colored zinc screws,...

self-locking nut is a nut that can self-lock by friction. The general nut will loosen itself due to vibration and other reasons during use. In order to prevent this phenomenon, the self-locking nut was invented. The main functions of self-locking nuts are anti-loose and anti-vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque type lock nuts (see GB/T3098.9-2002 national standard).

shaft card assembling device, comprising two struts, the same fixing plate is welded on the side of the two struts that are close to each other, the top of the fixing plate is symmetrically fixed with a motor, and the output shafts of the two motors are welded with * a bevel gear;

Rivet nuts, pull caps, and instant pull caps are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, instruments, furniture, and decoration. It is developed to solve the shortcomings of thin metal plate and thin tube welding nuts, such as easy melting and easy sliding of internal threads. Chinese name rivet nut, foreign name Rivetnut, blinddrivetnut, threadedforbid, rivnut, also known as rivet nut, is used in various metal sheets, pipes and other manufacturing industrial applications in railways, refrigeration, elevators, switches

The blind rivet is realized by pulling the core head. With the help of a force from the inside to the outside, under the action of the unidirectional pulling force, the pulling screw is pulled upwards, which causes the outer collar material to expand and deform, resulting in a sexual tightening force. , After the riveting is completed, the tension screw in the middle part breaks and falls out. Since a large pulling force is required to cause the rivet to expand and deform, the tensile screw is longer and accounts for about 60-80% of the total length of the rivet. At the same time, due to the limitation of the deformation mode, it is difficult for the blind rivet to be made into a hexagonal structure like a rivet nut, so the torsion resistance of its connection is low.
