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.

The present invention relates to a door-lock device (100) for locking and unlocking a door of a household appliance, such as a washing machine, a dishwasher and the like, comprising a first (110) and a second (120) electrical connecting terminal, a closing switch (130) series connected to said first connecting terminal (110) or to said second connection terminal (120), and arranged to close when the door of said household appliance is closed, an actuator (140), connected to said first (110) and second (120) connecting terminals, comprising at least one coil (141, 142), suitable to generate a magnetic field capable of causing the locking and unlocking of said door, and a Hall sensor (151) connected between said first (110) and said second (120) terminal, arranged in parallel with said actuator (140), said Hall sensor (151) being arranged so as to detect said magnetic field of said actuator (140).

A method for detecting a handed configuration of a door includes providing an electronic lock, which includes a latch assembly that includes a bolt movable between an extended position and a retracted position and a motor that is configured to drive the bolt between the extended position and the retracted position. The latch assembly includes a control circuit for controlling the motor to selectively move the bolt, at least one sensor in electrical communication with the control circuit, and at least one orientation indicator. The method includes detecting the presence of the at least one the orientation indicator and identifying a handed configuration based on the detection by the at least one sensor. The method includes driving, by the control circuit, the motor based on the identified handed configuration. The control circuit identifies the handed configuration without moving the bolt between the extended position and the retracted position.

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.
