Abstract: A deadbolt lock includes a positioning member mounted to a lock part. A protective member includes a recess formed in one side thereof and is mounted to the lock part and the positioning member. A covered area is formed between the positioning member and the protective member. At least one fixing member is connected to the positioning member and located within the covered area. An outer cover is mounted to the protective member and the positioning member. The at least one fixing member is compact in size to reinforce the protective member to reduce manufacturing cost. The protective member and the outer cover are not damaged by impact from outside of the deadbolt lock to enhance safety features of the deadbolt lock.

Abstract: A separation structure for a lock packing assembly includes a rectangular board with multiple holes which accommodate the handle of a lock, and the mounting plate of the lock contacts the board. The board includes a panel extending from each of four sides thereof, and the panels each have a first bending line and a second bending line. Each of the panels is bent along the first bending line and toward the board. Each of the panels is bent along the second bending line to form a separation plate which is perpendicular to the board and located between the holes. The locks are installed through the holes and separated by the separation plates such that the locks do not hit each other. The lock packing assembly includes low cost and can protect the locks.

Abstract: A lock defining a rotating axis and being installed on a door includes a mounting plate, a fastening member and a first handle set. The mounting plate is disposed on a side of the door and includes a mounting plate body and a protruding lug connected to the mounting plate body. The mounting plate body includes a locking slot structure. The protruding lug includes a fastening hole. The fastening member is inserted through the fastening hole of the protruding lug to fix the mounting plate on the door. The first handle set is assembled on the mounting plate. The first handle set includes an engaging structure and a decoration cover. The engaging structure is engaged with the locking slot structure to fix the first handle set on the mounting plate. The decoration cover covers the mounting plate and includes an opening corresponding to the fastening hole.

Abstract: A fixing structure for a lock includes a mounting plate, a cover plate, and a drive plate. The mounting plate is fixedly disposed on a door plank and includes a guided post and a locking slot structure. The cover plate includes an obstruction post, a guiding slot, and an engaging structure. The drive plate has a protruding tab and is rotatably disposed on the cover plate. The cover plate aligns with the mounting plate through the guided post being slidably disposed in the guiding slot. The drive plate is configured to rotate with the cover plate such that the engaging structure engages the locking slot structure. A lock includes two handle sets and the fixing structure. One of the handle sets and the mounting plate are fixedly disposed at opposite sides of the door plank. The other handle set passes through the cover plate and connects with the drive plate.

Abstract: An electric lock includes a motor, a power input port, a first control system and a second control system. The first control system includes an input unit configured to receive input data, an internal power source, and a first processing unit configured to use electricity of the internal power source to control the motor to rotate according to the input data. The second control system includes a wireless unit configured to receive a wireless signal, and a second processing unit different from the first processing unit and configured to use electricity of an external power source to control the motor to rotate when data transmitted in the wireless signal matches predetermined data and when the power input port is electrically connected to the external power source.

Abstract: A double-door lock assembly includes a first lock and a second lock which are mounted to a first door and a second door, respectively. The first lock includes a first rotary member, a first magnetic member and a linkage member. The second lock includes a second rotary member having a driving portion and a second magnetic member. The first and second rotary members can be driven to rotate together to open or close the first and second doors simultaneously when the first and second magnetic members are attracted to each other and the driving portion on the second rotary member contacts against the linkage member on the first rotary member.
