    摘要： A door lock includes a latch slideably received in a case and an unlocking mechanism mounted in the case and operatively connected to the latch for moving the latch between a latching position and an unlatching position. The unlocking mechanism includes an unlocking mechanism having a shaft for moving a locking member between a front position in which the unlocking mechanism is locked and a rear position in which the unlocking mechanism is not locked. The shaft can be driven by a motor through wired or wireless control to rotate in a forward direction or reverse direction for locking or unlocking purposes.

    摘要： A clutch includes an outer box and an intermediate member pivotably connected to the outer box. The intermediate member is coupled with an outer handle to pivot therewith. A torsion spring is disposed between the intermediate member and the outer box and biases the intermediate member to an initial position. A coupling member is pivotably mounted between the intermediate member and the outer box and is operatively connected to a first latch of a latch device of a lock device. When the coupling member and the intermediate member are jointly pivotable, pivotal movement of the outer handle causes the first latch to move from the latching position or the unlatching position. When the coupling member is not jointly pivotable with the intermediate member, pivotal movement of the outer handle is incapable of causing movement of the first latch. A lock device with the clutch is also disclosed.

    摘要： A lock case interlockable with an anti-theft latch is mounted on a door. The lock case includes a latch coupled with a latch hole in a door frame for retaining the door in a closed position. The anti-theft latch can be operated to engage with the door frame. When the latch is picked, the anti-theft latch still remains engaged with the door frame to prevent opening of the door. When normally operated, an inner operating device or an outer operating device can be operated to disengage the latch from the latch hole while disengaging the anti-theft latch from the door frame, permitting easy, convenient opening of the door.

    摘要： An electric control door lock includes an inner operational device, an outer operational device, and a latch bolt operably connected to the inner and outer operational devices. A rotating shaft is rotatably supported in an activation member and includes a driving threaded in threading connection with a driving spring. When the rotating shaft is driven by a motor to rotate, the driving spring moves along a longitudinal axis to actuate the activation member. Movement of the activation member is used to control operation of the outer operational device, thereby permitting or not permitting movement of the latch bolt to the unlatching position.
