The door lock according to the invention comprises a lock body, a bolt, a follower, a driver on both sides of the follower, and a latch solution to connect at least one of the drivers in force transmission connection and out of force transmission connection with the follower. The door lock further comprises a baffle plate between the follower and the driver at least on one side of the follower. The baffle plate comprises at least one support surface, which is set against the lock body or against a part which is connected to the lock body in a fixed manner. The baffle plate can thus not be rotated in relation to the lock body. A baffle plate which cannot be rotated prevents turning force from being transmitted from the driver to the follower.

In an embodiment, the present application discloses a door lock, comprising: a knob, positioned on a side of a door; a lock body, disposed within the door; and a connecting assembly, comprising a connecting shaft, comprising a front end and an opposite, rear end; and a receiving piece, comprising a connecting shaft receiving portion and a knob receiving portion. The knob receiving portion is configured to fixedly connect to the knob, and the connecting shaft receiving portion is configured to receive and detachably connect to the rear end. In an installed state, the front end acts on at least a part of the lock body to control the open and close of the lock body. The connecting shaft receiving portion and the rear end further have at least two connecting mechanisms in a longitudinal axis direction, so as to adjust the distance between the knob and the lock body. The door lock can adapt to doors of different thicknesses by adjusting the distance between the knob and the lock body.

An electronic cylinder lock has a main body. The main body is provided with a rotary cam. A first shaft is connected to the rotary cam. The first shaft has a first engaging portion. The main body is provided with a second shaft. The second shaft has a second engaging portion. A control lever is connected to the second shaft. A driving source is connected to the control lever. The driving source can drive the control lever to pull the second shaft to approach the first shaft, so that the second engaging portion is engaged with the first engaging portion, thereby improving the joint stability between the second engaging portion and the first engaging portion.

A rotation converter according to certain embodiments generally includes a case, an input member, a shuttle, and an output member. The input member is rotatably mounted to the case, and is rotatable from an input member home position in each of a first rotational direction and a second rotational direction. The shuttle is movably mounted in the case, and is engaged with the input member such that rotation of the input member from the input member home position in each of the first rotational direction and the second rotational direction drives the shuttle from a shuttle home position to a shuttle actuated position. The output member is rotatably mounted to the case and engaged with the shuttle such that the output member rotates in an output member rotational direction in response to movement of the shuttle from the shuttle home position to the shuttle actuated position.

Discloses is a lock for releasably locking a first component to a second component. The lock includes a driving assembly, configured to be installed on the first component and including a rotatable cylinder housing; a transmission assembly, including a cylinder core which insertable by a key and is in torque-transmission connection with the driving assembly; and a locking assembly, connected with the transmission assembly and having a first position decoupled from the second component and a second position coupled with the second component, wherein the driving assembly can move relative to the first component and drive the locking assembly by means of the movement to complete the locking, and the locking includes: making the locking assembly move to the second position from the first position and be locked there.

An anti-ligature lock having a locking mechanism for retracting a latch between a locked and an unlocked position. The anti-ligature lock includes a lock handle rotatable about the axis and operatively connected to a lock mechanism hub to rotate the hub and retract the latch between the locked and the unlocked positions. The anti-ligature lock includes a connector between the hub and the lock handle and rotatable about the axis, the connector having a female portion having an opening with walls elongated in a direction normal to the axis and a male portion having projections extending in opposite directions normal to the axis, the male portion extending within the female portion opening and having a neutral position wherein one of the male or female portion may be partially rotated in either direction about the axis with respect to the other of the male or female portion without the male portion projections contacting the female portion opening walls.

A door lock system includes a toolless handing assembly that selectively sets a handle in a left or right home position. The handing assembly may cooperate with a disc and a spring that biases the disc to a default position. The disc may be rotated in a first direction to set the disc in a first home position. A catch may engage the disc to retain the disc in the first home position. The catch may be released to return the disc to the default position and the disc may be rotated in a second direction to set the disc in a second home position, opposite the first home position.

A door lock system that adjusts to doors of different thicknesses. The door lock system may include self-adjusting spindles that engage and center a lock body in a door. The spindles may exert equal and opposing forces that center the lock body within the door and align the lock body with a latch.

A latch includes a housing that has a first side and a second side. The latch includes a bolt assembly that is positioned at least partially within the housing. The bolt assembly includes a bolt movable between an extended position and a retracted position relative to at least one of the first and second sides of the housing. The bolt is biased toward at least one of the extended position and the retracted position, and the bolt is positionable so as to selectively extend from either the first side or the second of the housing in the extended position.

An apparatus comprising an inner part including an external thread and a slot with a non-circular cross section in a plane perpendicular to the screw axis of the external thread. The slot is configured to locate an elongate member with a corresponding non-circular cross section, such that when located in the slot the elongate member is rotatably fixed relative to the slot. The apparatus further comprises an outer part including an internal surface that comprises a threaded portion, wherein the outer part is configured to threadably rotate around the inner part.
