EASILY-ASSEMBLED MODULAR DOOR LOCK

摘要

The modular door lock includes a tubular shell with a lock tongue at an open end and a turning wheel in the shell. The outer edge of the turning wheel extends out to a flange. A support frame lies between the turning wheel and the lock tongue and a drive is set in the frame. The lock tongue is permanently connected with a connection strap, which is drive-jointed with the turning wheel flange end via the drive. The door lock has a first state causing the lock tongue to draw back into the shell opening end through the drive and the connection strap, as well as a second state that causes the lock tongue to automatically reach outwards, the turning wheel to automatically rotate to the initial position, and the connection strap and drive mechanism to automatically return to their initial positions under the movement of the tongue.
