Transmission mechanism of mortise-blade lock

Abstract

The invention provides a transmission mechanism of a mortise blade lock, which includes a lock core and a lock tongue moving structure assembly. The lock bolt moving structure assembly is provided with a lock case, a bolt plate, and blades. The groove is movably installed in the lock housing through the guide column, the blade is provided with a return spring and a locking tooth, the bolt plate is connected with a dead bolt, the bolt plate is provided with a dial tooth and a locking column; the lock cylinder is provided with a cam, and the cam There is a dial point and a concave-convex platform on the top. The concave-convex platform of the cam presses the blade to move, forcing the locking teeth in the blade to give way to the channel for the locking column to move. The dial point of the cam drives the dial teeth on the peg plate to move the peg plate. When the platform leaves the blade, the blade resets under the action of the return spring, and the locking teeth clamp the locking column, so as to achieve the purpose of locking the lock tongue at the same time after moving the lock tongue. The invention can improve the anti-theft performance of superposition of the mortise lock and the blade lock, is very convenient to use, and can be widely used in mechanical mortise door locks, mechanical blade door locks and electronic door locks.

Description

technical field [0001] The invention relates to the technical field of blade locks and mortise door locks, in particular to a transmission mechanism of a mortise blade lock.
