Abstract: A lock includes a lock casing having a lock cylinder hole, a pin replacing hole and a plurality of first pin holes; a lock cylinder rotatably arranged in the lock cylinder hole and formed with a plurality of second pin holes; a pin set including a plurality of first pins respectively accommodated in the first pin holes, and a plurality of second pins respectively accommodated in the second pin holes; an outer casing having an inner wall defining an accommodation space for accommodating the lock casing; and a pin plug including a main body having a first side abutting against the lock casing and a second side abutting against the inner wall, and a protruded block protruded from the first side for closing the pin replacing hole. The second side is opposite to the first side, and a shape of the second side corresponds to the inner wall.

Abstract: A housing of an electric lock includes a first casing having a first and a second side walls arranged at two opposite sides of the first casing, and a second casing mounted between the first and second side walls. The second casing is formed with a first buckle structure adjacent to the first side wall and a first rebound structure abutting against the first casing. The first buckle structure includes a first elastic arm extended along a height direction of the second casing, and a first protrusion protruded toward the first side wall. The first rebound structure is configured to push the second casing away from the first casing along the height direction. The first side wall is formed with a first blocking part configured to abut against the first protrusion to prevent the second casing from moving away from the first casing along the height direction.

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.
