Title: A bolt having an anti-loosening spring
Inventor: CHO HAN BAEK
IPC: F16B37/12
Filed: 2020-01-10
Abstract: The present invention relates to a bolt that the loosening of the bolt can be prevented even after long-term use by the action of a spring coupled to the bolt. When a front end of the spring is in a fixed end state in which a position is fixed along a rotational direction of the bolt body and the rear end is in a locking position state which is in a free end state, the spring provides a reaction force that prevents rotation in the loosening direction. The front end of the spring is released from the fixed end state and converted to the free end state by the rotational force of the loosening direction torque greater than the threshold value. When the rear end of the spring is coupled in the unlocking position state, which is the fixed end state, the rear end of the spring operates to remove the reaction force in the loosening direction of the spring.
