Abstract: An electronic lock includes a latch mechanism and a rotation assembly. The rotation assembly includes a rotator, a single sensor and a processor, the rotator can be rotated toward a first direction or a second direction to drive a latch of the latch mechanism to be extended or retracted. The sensor is provided to sense a protrusion, an auxiliary protrusion, a recess and an auxiliary recess of the rotator to output a sensing signal. The processor is electrically connected to the sensor to receive the sensing signal and is provided to distinguish whether an actuation of extension or retraction of the latch is complete according to a potential variation of the sensing signal.

Abstract: An electric lock includes a housing, a keypad module and a lock assembly. The keypad module is arranged on the housing. The keypad module includes a key panel, an electrode pad, a circuit board and a spacer. The key panel is marked with a plurality of key characters. The electrode pad is arranged on an inner side of the key panel, and the electrode pad has a plurality of key electrodes corresponding to the plurality of key characters respectively. The circuit board includes a plurality of key circuits. Each of the key circuits is configured to generate a key signal when contacting a corresponding key electrode. The spacer is configured to form a gap between each of the key circuits and the corresponding key electrode. The lock assembly is electrically connected to the keypad module for performing locking and unlocking operations according to the key signal.

Abstract: A door lock includes a main part including an axial tube and a connection tube extending on two ends thereof. A mounting plate has a mounting hole and at least one first engaging portion. A first plate has at least one second engaging portion which faces the mounting plate. Multiple first fixing members extend through the first plate and are not connected to the mounting plate. A second plate is mounted to the connection tube and includes multiple positioning holes. Multiple fastening members extend through the positioning holes and are connected to the first fixing members. The second connection portion is threadedly connected to the first connection portion to adjust a distance between the mounting plate and the main part so that the door lock can be installed to doors of different thicknesses.

Abstract: A rekeyable lock includes a cylinder, a plug and a blocker. The cylinder includes a main body, an accommodation hole and a through hole penetrating through the main body and communicating with the accommodation hole. The plug is rotatably disposed in the accommodation hole. The blocker is movably disposed in the accommodation hole and includes a block portion and a position portion connecting with each other. The block portion is located between the main body and the plug. The position portion protrudes outside the accommodation hole via the through hole and positioned on a steady portion of the main body. The bottom pins can be removed from or blocked in the plug by the blocker for key replacement, and the position of the block portion can be easily adjusted by the position portion protruding outside the accommodation hole for rapidly replacing the bottom pins.

Abstract: A door lock and a method for installation and un-installation of the door lock, includes a lock plate unit and a lock unit. The lock plate unit having an installation hole, an inside face and a cylinder hole. The installation hole includes a first guide and the lock unit includes a second guide. The lock unit includes a latch unit. When installing the door lock, the lock unit is simply installed to the installation hole and rotated. When un-installing the door lock, the latch unit is simply pushed to be disengaged from the cylinder hole, and the lock unit is rotated to remove the lock unit from the lock plate unit without using any tool and without damaging the lock plate unit.

Abstract: A control method includes the electric lock entering an administrator setting mode after receiving an administrator password; the electric lock generating an authentication code in the administrator setting mode; the electric lock wirelessly receiving a first input from a portable device; the electric lock comparing the first input with the authentication code; the electric lock pairing with the portable device and receiving unique identification information of the portable device when the electric lock determines that the first input matches the authentication code; the electric lock storing the unique identification information of the portable device; and the electric lock performing an unlocking operation when the electric lock receiving a second input and sensing the portable device having the unique identification information within a predetermined distance.

Abstract: A rebound apparatus for a lock assembly includes a rotation axle, a driving plate and a torsion spring. One end of the rotation axle is passed through a through hole of a tube to connect with a body of the lock assembly, and the other end of the rotation axle protrudes from the tube. The driving plate is disposed in the through hole and is connected with the rotation axle for simultaneous rotation. The driving plate includes a first notch and a second notch which respectively coincide with a first blocking notch and a second blocking notch of the tube. The torsion spring includes a first pushing portion extending to the first notch and the first blocking notch, and a second pushing portion extending to the second notch and the second blocking notch.

Abstract: A lock knob assembly includes a knob body, a cover and a coupling member. The knob body is provided for covering a lock cylinder, and the cover is provided for covering the knob body. The lock knob assembly utilizes the coupling member to selectively couple the cover and the knob body, thus allowing the cover to couple with or separate from the knob body.
