  • Patent number: 11905737
    Abstract: An exemplary embodiment provides an electric lock, comprising: (a) a knob; (b) a lock body; (c) a rotatable shaft comprising a rotatable-shaft front end and an opposing rotatable-shaft rear end, wherein the rotatable-shaft rear end is fixedly connected to the lock body to control a locking and unlocking of the lock body; (d) a gear assembly comprising a gear and a movable piece with a common axis center; and (e) a motor assembly for driving the gear to rotate. The knob and the rotatable shaft are connected via the movable piece; the movable piece interacts with the gear via a mechanical barrier, such that electrically driving the gear by the motor assembly causes the movable piece to rotate; and the movable piece can pass over the mechanical barrier when a sufficient rotational force is applied to the knob, such that the movable piece is free to rotate relative to the gear, thereby allowing a user to manually control the locking and unlocking of the lock body.

  • Publication number: 20230014486
    Abstract: 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.

  • Patent number: 9334502
    Abstract: The present invention discloses the use of a human NLK gene and associated drugs thereof. The present invention discloses the use of the NLK gene for tumor treatment, tumor diagnosis and drug preparation. The present invention further constructs an isolated molecule that attenuates expression of the NLK gene of tumor cells, cells comprising the isolated molecule and a NLK interference lentivirus, and discloses the use thereof as well. The isolated molecule or the NLK interference lentivirus that attenuates expression of the NLK gene provided in the present invention can specifically attenuate expression of the human NLK gene, especially the lentivirus, can effectively infect target cells, efficiently inhibit the expression of the NLK gene in target cells, and inhibit the growth of tumor cells, thus has great significance in tumor treatment.
