摘要： A rotary cylinder assembly, including a rotary cylinder housing assembly and a spindle transmission assembly, wherein the spindle transmission assembly is arranged on one side of a latch or used individually; and a rotary cylinder housing assembly is arranged at the other end of the spindle transmission assembly and configured to drive the spindle transmission assembly under an external force to rotate to realize deadlocking. The rotary cylinder assembly drives the spindle transmission assembly by driving the rotary cylinder housing assembly to toggle the latch toggling sleeve to drive a bolt of the latch to extend, or drives a toggling adaptor of the spindle transmission assembly to directly hook or clamp a certain fixed part of a to-be-locked object, thereby realizing keyless mechanical deadlocking of the mechanical deadbolt lock.

摘要： A lock includes a lock housing, a cylinder assembly rotatably arranged in the lock housing and a locking keyless assembly connected to the cylinder assembly in a transmission way. The cylinder assembly includes a cylinder core and a tailpiece unit, a first clutch mechanism is provided between the cylinder core and the tailpiece unit, and a second clutch mechanism is provided between the locking keyless assembly and the tailpiece unit. When the second clutch mechanism is engaged, the locking keyless assembly is movable relative to the lock housing in a first direction under a driving of an external force for locking, and the cylinder core and the tailpiece unit rotate along with the locking keyless assembly. When the external force on the locking keyless assembly is withdrawn, the locking keyless assembly moves in an opposite second direction opposite, so that the second clutch mechanism switches to a disengaged state.

摘要： A locking device comprises a latch, a spindle and a rotary assembly. The latch is fixed to an object to be locked for engaging with a bore of a strike; the latch has a bolt which locks the object. One end of the spindle is detachably connected to the latch to drive the bolt to move towards or away from the bore. The rotary assembly is disposed at the other end of the spindle, which comprises a cylinder body and a rotary body, the cylinder body is rotated by the rotary body as it rotates, wherein one end of the rotary assembly is provided with a spindle driving means engaged with the other end of the spindle to drive the spindle to rotate. The rotary assembly drives the spindle to rotate via the spindle driving means, and the spindle drives the bolt to move approaching the bore to realize locking.

摘要： A dead-locking control mechanism for a door lock includes: a lock body; a fixing assembly; a rotatable spindle assembly having a first end rotatably connected with the fixing assembly and a second end in torque transmission connection with the bolt of the lock body, such that the bolt is drivable to extend beyond or retract into the fixed object; and a dead-locking control assembly including a stopping member arranged at the first end of the spindle assembly. The stopping member is movable between first and second positions relative to the spindle assembly, wherein in the first position, a first end of the stopping member is engaged with the fixing assembly and locked relative to the fixing assembly to thereby prevent the spindle assembly from rotating, and wherein in the second position, the stopping member is released from fixing assembly and thus the spindle assembly is capable of rotation freely.
