Abstract

The invention relates to a gear drive mechanism of a door lock. The gear drive mechanism of the door lock comprises a lock body and a lock tongue pulling plate in the lock body. A gearbox is fixed to the bottom of the lock body, and a driving gear, two intermediate gears and a driven gear are arranged in the gearbox. The driving gear is composed of an upper layer and a lower layer, the upper layer is a linkage ring, and the lower layer is a gear ring. An inserting groove matched with installation of a lock cylinder is formed in the driving gear in the axial direction, and the inserted lock cylinder drives the driving gear to rotate through the linkage ring. The gear ring of the driving gear are engaged with the two intermediate gears which are engaged with the driven gear, and two eccentric pins are fixed to the upper end of the driven gear in the axial direction and matched with transmission grooves formed in the lock tongue pulling plate. Through the specific design of the gear drive mechanism, the gears in the lock body operate in the gearbox, so that operation stability is greatly improved; and the gear drive mechanism has the advantages of being convenient and flexible to operate and use, high in reliability and long in service life.

Description

technical field [0001] The invention relates to a gear transmission mechanism of a door lock. Background technique [0002] The assembly structure of traditional gear-driven door locks is relatively complicated, resulting in a large lock body, laborious opening and closing operations, and poor flexibility. Contents of the invention [0003] In order to overcome the problems of complex structure design of the gear transmission mechanism of the ordinary door lock in the prior art, resulting in a large lock body, laborious opening and closing operation, and poor flexibility, the present invention provides a gear transmission mechanism of the door lock. The gear transmission mechanism of the lock has compact structure design, convenient and flexible operation, high reliability and long service life. [0004] The technical solution adopted by the present invention to solve the technical problem is: comprising the lock body and the bolt pull plate in the lock body, fixing the g...
