AI Technical Summary

Benefits of technology

This new type of locking mechanism for bolts used in vehicles was developed during this patented process. It uses an improved design made from copper or aluminum material without requiring expensive machining processes like turning it into threaded holes. By doing away with traditional methods such as drilling threads, millings, etc., these improvements resulted in more precise parts while maintaining their strengths over longer periods of use compared to previous designs. Additionally, there are no protruders near certain points within the structure where they were located due to its shape being circularly shaped rather than rectangular. Overall, this innovation provides technical benefits including increased efficiency, reduced failures rates, enhanced durability, and greater flexibility when adjustable.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the design of bolted joint systems that can resist torsional stress caused by vibrations or shock loads while maintain their effectiveness at extreme temperatures (such as those associated with automobile engines).

Abstract

The invention provides a locking fastener with a tenon. According to the locking fastener, one-time cold extrusion forming can be achieved, all borne impact forces can be gathered to a damping bag, the impact forces are completely eliminated through deformation of the damping bag and change of the flowing track of gas in the damping bag, and the impact forces cannot be transmitted to a screw rod;an elastic assembly is arranged, a string can be directly pulled to drive a positioning piece, the positioning piece can rotate around a connecting rod, then the positioning piece can be clamped in asquare neck, and the application range of a round-head square-neck bolt is enlarged; and a notch is formed in the square neck, the square neck can be better placed in a through hole of an object, partof the notch can be embedded in a round hole, inclination of the screw rod can be relieved, and a nut can be better screwed on.
