Abstract

The invention discloses a nut locking structure. The nut locking structure comprises a main body and locking nuts, and the main body and the locking nut lock the main body and a screw through at leastone locking mechanism; a thread is formed in an inner ring of the main body, the locking mechanism comprises locking parts formed on the side wall of the main body, and the locking parts protrude from the side wall of the main body and are gradually lowered in the clockwise direction; and grooves which are matched with the locking parts are formed in the inner walls of the locking nuts, lock parts are arranged on one sides of the grooves in the anti-clockwise direction, the depth of the lock parts are gradually decreased in the clockwise direction, and protrusion blocks are arranged at the initial ends of the lock parts. According to the nut locking structure, the locking parts are arranged on the main body, matched lock parts and protrusion blocks are arranged on the locking nuts, forward and reverse rotation of the locking nut during a locking condition is limited, and the reliability of locking of the nut is ensured; and meanwhile, the protrusion blocks can show operation personnelwhether the locking nut is under a locking state or not.

Description

technical field [0001] The invention relates to the field of fastening structures, in particular to a nut locking structure. Background technique [0002] At present, the nuts used in industry have poor self-locking effect after tightening. When used in a vibrating environment, the nuts may loosen. It is common and poses a great security risk. Contents of the invention [0003] Aiming at the above defects in the prior art, the main purpose of the present invention is to overcome the deficiencies of the prior art, and discloses a nut locking structure, including a body and a lock nut, the body and the lock nut pass through at least one locking mechanism locks the body and the screw; [0004] The inner ring of the body is provided with threads, the locking mechanism includes a locking portion provided on the side wall of the body, the locking portion protrudes from the side wall of the body, and the locking portion is along the The clockwise direction gradually decreases,...
