AI Technical Summary

Technical Problem

Traditional threaded inserts are prone to loosening in vibrating environments, resulting in unstable connections. Furthermore, the small contact area between the screw head and the insert surface leads to deformation, affecting the stability and safety of the connection.

Method used

A special-shaped threaded sleeve is designed, comprising a slot, a washer, a locking block, a sleeve, a pressure head, a top pressure plate, a metal locking plate, and an anti-slip block. By increasing the contact area between the screw head and the top of the threaded sleeve, and by using the anti-slip block to tightly fit against the inner wall of the connector to increase friction, loosening and falling off are prevented.

Benefits of technology

It effectively prevents the threaded sleeve from loosening and deforming, improves the stability and safety of the connection, and avoids the threaded sleeve from slipping off the connecting parts.

Description

TECHNICAL FIELD

[0001] The utility model discloses screw set installation technical field, specifically is a special-shaped screw set with antiskid function. BACKGROUND

[0002] In many mechanical connection fields, screw sets are widely used to enhance the strength of threaded connections, repair damaged threaded holes, etc. However, in many actual working conditions, equipment often suffers from different degrees of vibration. The traditional screw set relies on the friction force between the threads to fix. Under the influence of such repeated vibration, the small gap between the threads will gradually expand, and the friction force will continuously decrease, eventually leading to screw set loosening. In severe cases, the connecting parts may even fall off, endangering the safe operation of the entire equipment. Moreover, when the screw is directly tightened with the screw set, the contact area between the screw head and the surface of the screw set is relatively small. During the tightening process of the screw, the force will be concentrated on this small contact area, resulting in a large pressure and causing the surface of the screw set to deform, thereby affecting the stability and flatness of the connection. To solve the above problems, a special-shaped screw set with antiskid function is needed.

[0003] The existing special-shaped screw set cannot prevent slipping and has poor connection stability during operation. Therefore, there is an urgent need for a special-shaped screw set with antiskid function. SUMMARY
