An LED display screen lock includes a handle, a lock seat and a lock core. The lock seat includes a base, a through hole and a pin slidably disposed on the base. The lock core is rotatably disposed on the handle and received in the through hole. A locking hole is formed on the lock core and the pin is inserted in the locking hole. An unlocking portion is disposed on a circumference of the handle. The unlocking portion is abutted against the pin, in order to drive the pin to exit the locking hole.

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.

The present invention relates to a handle arrangement (1) comprising a locking mechanism (10), a blocking mechanism (20), a handle (30), a display unit (50), and a control unit (40) communicatively connected to a remote server (80) and configured to display a QR code on the display unit for a user to read, wherein the QR code is unique for the handle arrangement and the time period during which the QR code is displayed, receive, from a remote server, information that the user has communicated, to the remote server, a reading of the displayed QR code together with an identification of the user, and that the identified user is authorized to open the door, and either operate the blocking mechanism enabling opening of the door by means of the handle, or enabling a second level authorization function for the user to verify its authorization, and if access is granted, operating the blocking mechanism enabling opening of the door by means of the handle.

Systems and methods are disclosed for a lock assembly having a touchscreen. The lock assembly includes an interior assembly and an exterior assembly having an exterior lock housing and a touchscreen assembly. The touchscreen assembly includes a touchscreen having selectable icons on a front surface thereof, a printed circuit board assembly (PCBA), and a support structure. The PCBA includes input regions corresponding to the selectable icons and light emitters. The support structure is configured to reflect light emitted from the light emitters through the front surface of the touchscreen.

A storage apparatus having a keyless lock/unlock system. The storage apparatus may including a housing having a storage cavity and a door may be coupled to the housing. A handle is coupled to the door and defines a handle cavity. The locking system includes an electronics assembly and a locking mechanism that are in operable communication. The electronics assembly includes a reader component and an indicator component that are located within the handle cavity. The indicator component is visible through a window in the handle. When the reader component receives credential data which is then authenticated, the locking system transitions between a locked configuration whereby the locking mechanism is locked and the indicator component is in a first display state and an unlocked configuration whereby the locking mechanism is unlocked and the indicator component is in a second display state. The indicator component may be electronic paper.

A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

An electronic access system and method utilizes a modular latch system and method. The modular latch system and method include a reader module and latch module. The reader module includes a user interface with one or more readers or devices for receiving input from a user, and sending the input to a controller. The latch module is configured for mounting to a closure that provides access to the secure area. The latch module can be operated in a stand-alone mode while detached from the reader module. Alternatively, the latch module can be releasably engaged to the reader module and operated in an assembled mode. The modular system and method allow for engagement of the reader module to the latch module, disengagement of the reader module from the latch module, and engagement of an alternate reader module to the latch module for retrofitting the reader module with the alternate reader module.

The invention is related to construction, namely, discloses a shackle and a locking device comprising said shackle. The technical effect is improving the performance of the device due to a certain design of the shackle. The technical effect is achieved by the fact that the shackle comprises: a first end; a second end, and a plurality of bends between the first end and the second end, thereby forming: a first segment between the first end and a first bend, a second segment between the first bend and a second bend, a third segment between the second bend and a third bend, and a fourth segment between the third bend and the second end, wherein the first segment lies in a first plane and the fourth segment is substantially co-planar with the first segment, and the technical effect is also achieved by design options of the locking device comprising said shackle.

A system for a door includes a door lock having a handle assembly and a lock. The lock is movable between an engaged position and a disengaged position. An authentication module is mounted to the door lock at a position offset from a surface of the door. The authentication module is operably coupled to the lock.
