Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a multipoint lock. The multipoint lock may include a horizontally translating lock bolt and at least one vertical translating lock bolt. In addition, the multipoint lock includes a linkage coupled to and configured to translate the horizontally translating lock bolt and the at least one vertical translating lock bolt. Further, the multipoint lock includes a gear mechanism configured to actuate the linkage and to effect translation of the horizontally translating lock bolt and the at least one vertical translating lock bolt.

A door lock device and a door lock having the same, wherein the door lock device includes: a switch mechanism capable of being operatively switched from a first position to a second position or a third position; an oblique tongue mechanism, including an oblique tongue body and an oblique tongue drive assembly, the oblique tongue drive assembly being connected to the switch mechanism, wherein, when the switch mechanism is in the first position, the oblique tongue body is in an extended state, and when the switch mechanism is switched from the first position to the second position or the third position, the switch mechanism drives the oblique tongue drive assembly, to drive the oblique tongue body to be in a retracted state; a deadbolt mechanism, including a deadbolt body and a deadbolt drive assembly; and a linkage mechanism connecting the switch mechanism and the deadbolt drive assembly.

In a door lock, a locking mechanism includes an outer wheel, an inner wheel disposed inside the outer wheel and operable to rotate relative to the outer wheel, a clutch member disposed in the inner wheel and normally biased to radially extend from the inner wheel into the outer wheel to interengage the inner and outer wheels, and an arm plate sleeved around the inner wheel. When the inner wheel rotates in a first direction, the arm plate is driven by the inner wheel to actuate the deadbolt. When the inner and outer wheels are interengaged, the inner wheel drives the outer wheel by rotating in a second direction. When the inner wheel disengages from the outer wheel, rotation of the inner wheel in the first or second direction is idle relative to the outer wheel.

A lock capable of locking a movable door includes a lock shell having opening parts, and hook tongues extending out of the opening parts. The lock further includes lock tongue support frames, lock tongue reset springs, left and right first guide grooves, and shifting blocks. The lock tongue support frames are movably disposed on the lock shell and combined with shaft pins. The hook tongues have lower shaft holes and rotatably sleeve the shaft pins via the lower shaft holes. Each lock tongue reset springs has one free end combined with the lock tongue support frames, and another one free end combined with the hook tongues. The left and right first guide grooves are symmetrically-arranged and correspond to the shaft pins. Two ends of the shaft pins respectively extending into the left and right first guide grooves. The shaft pins drive the hook tongues to move to be unhooked or locked when the lock tongue support frames move to drive the shaft pins to move along the left and right first guide grooves. Axial centers of the shifting blocks have center holes that allow shifting sheets to be inserted therein. The lock tongue support frames are able to move back and forth to respond to rotation of shifting handles on the shifting blocks when the shifting blocks rotate.

The present invention relates to the field of lockset and provides a lock body a latch bolt installation structure comprising a latch bolt body having a driving part and a latch part, wherein the latch part is detachably connected with the driving part. The latch part is configured with a male part inserting into a female part on the driving part; the female part comprises a first installation position and a second installation position for installing the latch part; when the latch part is installed at the first installation position, a flat surface of the latch part faces towards a first direction; when the latch part is installed at the second installation position, the flat surface of the latch part faces towards a second direction which is opposite to the first direction. The present invention is advantageous in fast reversal of the installation of the latch bolt as well as the construction progress control and user experiences.

A door lock for a handle, comprises a housing, a rotatable connector inside the housing, a first elastic element and a second elastic element both arranged inside the housing. The rotatable connector is interacted with the handle. The first elastic element is at least configured to provide a restoring force for the handle to return to its origin position when the handle is rotated upward to lock the door, and the second elastic element is configured to provide a restoring force for the handle to return to its origin position when the handle is rotated downward to unlock and open the door, as well as to provide enough resistance to remain handle at its origin position when the handle is released. The door lock is effort-saving for the users to rotate the handle upward, and also adapted for various handles having different weights, to be remained at the origin position when the handle is released.

In a door lock, a locking mechanism includes an outer wheel, an inner wheel disposed inside the outer wheel and operable to rotate relative to the outer wheel, a clutch member disposed in the inner wheel and normally biased to radially extend from the inner wheel into the outer wheel to interengage the inner and outer wheels, and an arm plate sleeved around the inner wheel. When the inner wheel rotates in a first direction, the arm plate is driven by the inner wheel to actuate the deadbolt. When the inner and outer wheels are interengaged, the inner wheel drives the outer wheel by rotating in a second direction. When the inner wheel disengages from the outer wheel, rotation of the inner wheel in the first or second direction is idle relative to the outer wheel.

The present disclosure provides a smart door lock and a method for controlling the smart door lock. The method may be implemented on a computing apparatus including a processor and a storage device. The method may include obtaining user information and determining whether the user information passes a verification. The method may further include in response to a determination that the user information passes the verification, controlling the smart door lock to perform an unlock operation. The method may further include determining whether the door on which the smart door lock is installed has a preset action within a preset time period and in response to a determination that the door has the preset action within the preset time period, controlling at least one component of the smart door lock to perform at least one operation.
