The present disclosure provides a driving mechanism for a door lock and a door lock. The driving mechanism includes a motor, a planet gear assembly and a holding frame. The planet gear assembly includes a gear ring, a planet gear and a sun gear. The motor is rotatably coupled to the sun gear. The gear ring defines a receiving space. The planet gear and part of the sun gear are received in the receiving space. The planet gear is rotatably coupled between the sun gear and the gear ring. The holding frame is located on one side of the planet gear assembly. The planet gear is coupled to the holding frame. When the gear ring is in an unmovable state, the sun gear is rotated by the motor. When the sun gear is in an unmovable state, the gear ring is controlled to rotate.

A handle assembly for a window or door leaf having first and second opposing sides, the handle assembly having a forward end and a rearward end, the handle assembly comprising: a first handle grip, configured for mounting to a first side of the leaf, the first handle grip being moveable rotatably and axially relative to a first handle axis, and a second handle grip configured for mounting to the second side of the leaf, the second handle grip being movable at least rotatably relative to a second handle axis, each handle grip having a closed position, wherein the handle grip is in a first angular position and an open position, wherein the handle grip is in a second angular position, the handle assembly having a rest mode and a locked mode.

The application discloses an electronic door lock with an unlocking monitoring function and a working method thereof, belonging to the technical field of intelligent locks, which comprises a lock body, a mechanical unlocking member connected to a deadbolt assembly, a main control board arranged in the lock body, and a micro switch electrically connected to the main control board. The mechanical unlocking member comprises a knob that is rotatably arranged on the lock body, and a paddle that is synchronously and coaxially driven by the knob. When the knob drives the deadbolt assembly to switch between the locked state and the unlocked state, the paddle can be rotated to trigger the micro switch. A wireless transmitting module for transmitting the trigger signal of the micro switch is integrated on the control board. The mechanical unlocking monitoring function is added.

A clutch engagement assembly for a door lock device includes a first shaft having at an end thereof an insertion end portion in which a channel is formed; a second drive shaft having a hollow engagement end portion into which the insertion end portion of the first shaft is inserted; a driving member which provides a driving force; and a pin member that is installed in a state of being elastically supported in the engagement end portion of the second shaft and is movable by the driving member so as to extending through (be inserted in) at least a part of the first shaft and at least a part of the second shaft, thereby causing a clutch engagement or a disengagement between a first shaft and a second shaft. The clutch engagement assembly may provide a relatively small size structure of the door lock device and a firm engagement force.

A handle set includes a main body that has a handle and a faceplate positioned around the handle, the faceplate having a toggle aperture. The handle set includes a locking mechanism that includes a locking piece that has a locking notch. The locking mechanism includes a toggle positioned within a toggle housing, the toggle being movable relative to the toggle housing. The toggle includes a toggle tail configured to be received into the locking notch. The toggle includes a toggle head removably attached to the toggle tail, the toggle head being at least one of a privacy attachment button and a passage attachment button. At least a portion of the privacy attachment button extends from the toggle aperture and beyond the faceplate. The passage attachment button interfaces with the toggle housing to prevent relative movement between the passage attachment button and the toggle housing.

A latch assembly comprising an elongated flat latch slider slidable along a first axis between a first position and a second position in relation to a main latch, wherein the latch slider is provided with a protruding lug; a lock arrangement comprising; a body moving between a locking position and an unlocking position, wherein in the locking position a portion of the body is preventing movement of the lug along a path in parallel with said first axis, and in the unlocking position the lug can be moved along said first axis; and an electrically powered device connected to the body for moving the body between the locking position and the unlocking position.

A fixing structure for a lock includes a mounting plate, a cover plate, and a drive plate. The mounting plate is fixedly disposed on a door plank and includes a guided post and a locking slot structure. The cover plate includes an obstruction post, a guiding slot, and an engaging structure. The drive plate has a protruding tab and is rotatably disposed on the cover plate. The cover plate aligns with the mounting plate through the guided post being slidably disposed in the guiding slot. The drive plate is configured to rotate with the cover plate such that the engaging structure engages the locking slot structure. A lock includes two handle sets and the fixing structure. One of the handle sets and the mounting plate are fixedly disposed at opposite sides of the door plank. The other handle set passes through the cover plate and connects with the drive plate.

A tamper-resistant sash window lock includes a housing, a shaft, a cam, and a lever member. An interior surface of the housing wall that defines a cavity. A portion of the interior surface of the housing wall is curved about a hole in the housing, with a distal end of the wall portion formed into a lock surface. The shaft is rotatably mounted in the hole, and a hub of the cam is rotatably mounted on the shaft. The cam has a cantilevered arm with a lock surface and an engagement surface. The lever member is fixedly secured to the shaft, for a first side thereof to engage and drive the cam hub in a first rotational direction into a lock position when the shaft is actuated in the first rotational direction, so the lock surface of the cantilevered arm engages the lock surface of the housing preventing forced entry.
