Backing preventing lock body mechanism and touch type door lock

Abstract

The invention provides a backing preventing lock body mechanism and a touch type door lock and mainly solves the problem that most of the structures of the existing door lock backing preventing mechanisms are complicated. The touch type door lock is characterized in that a lock shell comprises an inner cavity and an opening which communicate with each other; a lock tongue is arranged in the innercavity and linearly moves for unlocking or locking, and when the lock tongue is located at a locking position, the front end of the lock tongue extends out of the opening and is exposed out of the lock shell; a blocking component comprises a first position at which the blocking component is driven by a rotating core to carry out blocking fit with the lock tongue when the lock tongue is at the locking position and a second position at which the blocking component moves away from the motion path of the lock tongue; and an elastic resetting component is used for pushing the rotating core and driving the blocking component to move towards the second position. According to the lock body mechanism and the touch type door lock, provided by the invention, the backing of the lock tongue is prevented through the motion of the blocking component, the structure is simple, and the use is convenient; and moreover, the touch type door lock provided with the mechanism is further provided, unlocking can be carried out through press rather than rotating, the structure is compact, and the demand on door opening space is low.

Description

technical field [0001] The invention belongs to the technical field of hardware, and in particular relates to an anti-retraction lock body mechanism and a touch-type door lock. Background technique [0002] The door lock is a hardware installed on the door to maintain the privacy of the space. Its basic structure includes a deadbolt that can perform telescopic movement under the action of external force, and cooperates with the buckle box installed on the door frame to prevent the door from being locked. It is opened by accidents such as wind blowing. [0003] Most of the door locks on the market now have an anti-card unlocking mechanism, which is used to prevent the door from being opened due to the retreat of the bolt under force. Most of the current anti-retraction mechanisms are more complicated in structure and difficult to assemble. Most of the locks are structures that are opened by twisting the handle, which requires a lot of space. Contents of the invention [0...
