A door assembly includes a door having opposing first and second surfaces and a hole defined in the door and extending between the first and second surfaces, a cylinder lock mounted to the second surface at the hole, and a cylinder dry lock assembly mounted to the door at the hole adjacent the first surface. The cylinder dry lock assembly including a main body that defines a central orifice, a low-friction member received within the central orifice, and an actuation mechanism extending from the low-friction member and engageable with the cylinder lock. Actuating the cylinder lock rotates the actuation mechanism, and the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces at the hole.

A lockset (10) is actuable by pivoting a lever (14,16) about a longitudinal axis of the lockset (10) by rotating the lever (14,16) and by pivoting the lever (14,16) about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset (10) includes an inside lever (14) and an outside lever (16), each associated with an independent mechanism, each of which can independently actuate the lockset (10). A keyed locking cylinder (250) is disposed axially in the outside lever (16) and pivots with the outside lever (16). The keyed lock cylinder (250) has an opening that pivotably engages an actuator (260). The actuator (260) extends into a retractor assembly (33) of the lockset (10) and is configured to perform an unlocking or locking function when actuated.

A lock cylinder includes a housing, in which a sleeve having a cylinder core accommodated therein is rotatably supported. The cylinder core has spring-loaded tumblers forming a form closure with recesses arranged in the sleeve when a key engaging the tumblers is removed. Inside the housing, the sleeve is coupled to a coupling element by means of a disengaging sleeve. The coupling element is supported inside the housing and connected to a bearing in a rotationally-fixed manner. The bearing supports an output element. At least one of the sleeve and the coupling element forms a form closure with the bearing to block the rotation of the output element if an improper object is used in operative connection with the cylinder core.

A household electric and mechanical dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a locking head, a springback lock tongue, a first round rotary table and a fixed seat, wherein: an end portion of the springback lock tongue extends outside the fixed seat, an arched guide rail which is fitted with the first round rotary table is located on the springback lock tongue. The intelligent electronic control structure includes a PCB (printed circuit board), a motor, a scalable suite and a second round rotary table, wherein: one end of the scalable suite is fixedly connected with the motor, the other end of the scalable suite is fixedly connected with the second round rotary table, an arched guide rail which is fitted with the second round rotary table is located on the other surface of the springback lock tongue.

A vehicle door lock device includes a door handle base provided at a vehicle door and provided with a cylinder lock, and a door latch mechanism provided at the vehicle door. The cylinder lock includes a key cylinder, a paddle portion operably and detachably coupled to the door latch mechanism and configured to transmit rotation of the key cylinder to the door latch mechanism, and a support portion configured to rotatably support the paddle portion. The door latch mechanism includes a key rotor into which the paddle portion is detachably inserted. The paddle portion is supported on the support portion to rotate between a direction of a center axis of the support portion and a direction inclined with respect to the center axis.

A housing configured to accept a rekeyable lock core for use in lockable enclosures. The housing is configured to use a lock core that is designed for deadbolt and door lever/knob operation. The housing allows a rekeyable lock cylinder to be used in one's home as well as other enclosure enclosures. A common key may therefore be used for all devices as the lock core is of a rekeyable design.

A lock set transmission mechanism includes a lock case, a lock core, a transmission rod, a supporting member and a fixing member. The lock core is arranged on the lock case and configured to be driven by a key to rotate relative to the lock case. The transmission rod has a first end configured to be connected to a latch, and a second end. The supporting member includes a first supporting ring sleeved on the lock core, a second supporting ring configured to support the second end of the transmission rod, and at least one supporting rib connected to the first and second supporting rings. The fixing member is configured to fix the supporting member to the lock core. Wherein, when the lock core is rotated relative to the lock case, the transmission rod is driven by the lock core to rotate, in order to move the latch.

A lock mechanism includes a plug assembly, a transmission spindle, a bush and a latchbolt assembly. The transmission spindle is coupled to the plug assembly. The bush and the transmission spindle are coupled as one piece to allow the transmission spindle to drive the bush rotate. The latchbolt assembly includes a latchbolt and an actuation element having an actuation hole. The bush, movably accommodated in the actuation hole, is provided to drive the actuation element in swinging movement to move the latchbolt. Because of the bush movably accommodated in the actuation hole, the latchbolt assembly can move toward or away from the plug assembly and the lock mechanism can be mounted on doors having different thicknesses.

A vehicle door lock device includes a door handle base provided at a vehicle door and provided with a cylinder lock, and a door latch mechanism provided at the vehicle door. The cylinder lock includes a key cylinder, a paddle portion operably and detachably coupled to the door latch mechanism and configured to transmit rotation of the key cylinder to the door latch mechanism, and a support portion configured to rotatably support the paddle portion. The door latch mechanism includes a key rotor into which the paddle portion is detachably inserted. The paddle portion is supported on the support portion to displace in a far-near direction relative to the key rotor.
