Abstract
The invention discloses a practical lock nut which comprises a hexagon nut part, an anti-loose part, an internal spring, a limiting step and a rotating set. The anti-loose part is provided with a spring stretching-out opening, a spring fixing opening and a center hole. The internal spring comprises a spring fixing end, a spring stretching-out end and a spring ring part. By means of the practical lock nut, due to the fact that an internal spring ring is additionally arranged on the nut, the phenomenon that the nut is loosened due to long time machine vibration of a bolt and the nut can be effectively prevented, and therefore an anti-loose effect of the nut is improved. In addition, a rotating set device is additionally arranged on the lock nut, the internal spring can be loosened and tightened more conveniently, and therefore the lock nut can be used more conveniently.
