An electric strike lock is disclosed. The electric strike lock cooperates with a lock when in use. The lock has a lock tongue. The electric strike lock includes a base. The base has an opening for accommodating the lock tongue. The base has a pair of grooves corresponding to two opposite sides of the opening. Two sliding members are slidably disposed in the respective grooves. The sliding members are connected with at least one driving unit for the sliding members to slide closer to each other so that the lock tongue is engaged in the opening, or for the sliding members to gradually slide away from each other so that the lock tongue is disengaged from the opening, thereby performing locking and unlocking operations on a door in a sliding manner.

An interconnection assembly includes a chassis, and cam plates that are rotatably coupled to the chassis to pivot about a plurality of rotational axises. An upper cam plate is operatively coupled to a deadbolt. The upper cam plate has a cam surface. A lower cam plate is rotatably coupled to the chassis to pivot about a second rotational axis. The lower cam plate is operatively coupled to an interior latch bolt handle. The lower cam plate has a cam slot. A linkage bar is rotatably coupled to the chassis to pivot about a pivot axis. The linkage bar has a first linkage portion having a first cam follower configured to operatively engage the cam surface of the upper cam plate and has a second linkage portion having a second cam follower operatively received in the cam slot of the lower cam plate.

A latch or connector system having a latch housing, a first latching component, a second latching component, and a handle. The first and second latching components are movably mounted to the latch housing, and movable respective latched and unlatched positions. The handle is movably mounted to the latch housing and operatively associated with the first latching component and the second latching component. The handle is movable from a closed handle position to an open handle position to cause the first latching component and the second latching component to move from their respective latched positions to their respective unlatched positions, and the handle is movable from the open handle position to the closed handle position only when the first latching component and the second latching component are in their respective latched positions.

A door lock device is provided and includes: a housing, an acting assembly arranged in the housing and having a lock tongue, an operating assembly arranged in the housing and interlocked with an outdoor handle, and a regulating assembly arranged in the housing for a user to regulate the operating assembly into an interlocking state or an idle state. As such, in the interlocking state, the outdoor handle drives the acting assembly through the operating assembly to cause the lock tongue to extend or retract relative to the housing, and in the idle state, the operating assembly cannot drive the acting assembly and the outdoor handle cannot be interlocked with the lock tongue.

A door lock system comprising a first rotary configured to control extension and retraction of the deadbolt via a primary cam mechanism; a second rotary control configured to control extension and retraction of the latch; and a link configured to retract the deadbolt in response to operation of the second rotary control when the latch is retracted by the second rotary control. The link is configured to move along a linear path normal to the movement of the deadbolt and the door latch and to contact the primary cam mechanism upon the link movement to affect deadbolt retraction and extension. A lever may be used to retract the latch in response to rotation of the first rotary control in a first rotational direction when the deadbolt is retracted by the first rotary control.
