The locking thread insert is a new variety developed on the basis of the ordinary thread insert. There is one circle or multiple polygonal thread locking rings in the middle part of the locking thread insert. When the bolt is screwed into the threaded hole of the locking thread insert and the bolt enters the polygonal locking ring, the polygon needs to be expanded to deform the locking edge. At this time, the screw needs to overcome the friction force given by the locking edge when being screwed in. After the screw is tightened, this friction force can prevent the screw from loosening by itself. The thread locking and anti-loosening performance of the locking thread insert is superior to that of some other common locking devices, with higher strength and it can also be disassembled repeatedly.
The locking thread insert is a new type of internal thread fastener. It is made of corrosion-resistant diamond-shaped section steel wire with high strength, high precision and high surface quality. Its appearance is like a spring. When the locking thread insert is installed in the threaded hole, the outer surface of the locking thread insert fits on the threaded hole by elastic force, and its inner surface forms a new thread for screwing in screws or bolts, so that the screws or bolts do not directly contact the base body, protecting the base body and the screws, and playing the roles of prolonging the service life of the thread, increasing the connection strength of the thread, increasing the stress surface of the thread, increasing the bearing capacity and anti-fatigue strength of the thread connection, and preventing loosening due to earthquake.
Locking thread insert products are commonly used in aerospace industry, shipbuilding industry, automotive power machinery, hydraulic transmission machinery, pneumatic tools, mold manufacturing and assembly, pneumatic components, chemical fibers, textiles, machinery, optical instruments, electrical appliances, high-voltage switches, automotive repair and other industries' products and equipment.
