Use of self locking nut

Lock the external connector or other pipe fitting of the through wire. The nut is connected with the locking mechanism. When the nut is tightened, the locking mechanism locks the ruler body, and the ruler frame cannot move freely to achieve the purpose of locking; When the nut is released, the locking mechanism unlocks the ruler body and the ruler frame moves along the ruler body. Self-locking nuts are generally based on friction, the principle is through the embossing teeth into the sheet metal preset hole is also, generally and the aperture of the square preset hole is slightly smaller than the pressure rivet nut. General nuts in the process of use due to vibration and other reasons will loosen themselves, in order to prevent this phenomenon, so self-locking nuts were invented. Self - locking nut its main function is anti - loosening, anti - vibration. Used on special occasions.

Self-locking nuts having nylon ring inlaid, with neck closing, with metal release device. They all belong to effective torque type locknut. Can refer to GB/T3098.9-2002 national standard. The common foreign self-locking nuts are usually the high-strength self-locking nuts of LANFRANCO ships and Bridges of France, which can convert the friction force into the expansion force between the bolt and the groove nut to achieve excellent locking effect. Some of the self-locking nuts in the thread mouth with nylon material, in place when the installation due to the damping effect of nylon nut is not easy to loose, some in the thread mouth to do a certain amount of deformation of the thread, also make a certain damping between the nut and the screw. In order to prevent loosening of ordinary nuts during installation, spring spacers are generally added to prevent loosening.
