The control mechanism comprises a lock assembly, a lock-in and lock-out mechanism, a swinging piece and two switching pieces, wherein the lock-in and lock-out mechanism comprises an installing shaft, the installing shaft is located between lock cores of an indoor lock and an outdoor lock, the position of the installing shaft is fixed relative to lock core shafts, and the installing shaft is independent of the lock core shafts; the swinging piece is rotationally arranged on the installing shaft and is provided with sliding pins which are used for pushing a bolt plate to move along the lock-in and lock-out direction; the two switching pieces are used for respectively driving the swinging piece to rotate around the installing shaft under the driving of the corresponding lock core shafts; one switching piece does not rotate synchronously when the swinging piece is driven to rotate by the other switching piece; a gap which is used for a bolt plate to move along the lock-in and lock-out direction is reserved between the lock core of the indoor lock and the lock core of the outdoor lock.

Description

technical field

[0001] The invention relates to the technical field of locks, in particular to a double-opening lock head control mechanism. Background technique

[0002] The lock generally includes a lock head, a door lock bolt plate that is controlled by the lock head to protrude or retract in the direction of locking in and out, and a locking mechanism for the door lock bolt plate. In order to simplify the lock structure and reduce production costs, the applicant previously submitted a Chinese patent application document, the application number is 2012104412406, a door lock locking device, including a deadbolt plate, which can move linearly back and forth along the lock in and out direction. It is arranged in the lock case and is subject to the lock-out bias force pushed out along the lock-out direction; the bolt plate is formed with a traction groove; the pendulum is driven by a power shaft rotatably arranged on the lock case, and can It is reciprocally arranged in the ...
