Abstract: A door lock disposed on a door leaf includes a casing, a bolt member, a latch member, an auxiliary latch member and a transmission unit. When the door lock is in an open state, the bolt member is retracted into the casing and held by the transmission unit. During a closing operation of the door leaf, the latch member and the auxiliary latch member are successively pushed into the casing to actuate the transmission unit, so that the transmission unit releases the bolt member when the door leaf is closed, and that the bolt member automatically projects out of the casing to lock the door leaf.

Abstract: An electronic door lock includes a dead bolt moved by a deadbolt transmitting assembly, a spring-loaded latch bolt moved by a latchbolt transmitting assembly, a lock core rotated by a core transmitting assembly, and a spring-loaded prying resisting member. A monitoring unit includes sensors respectively corresponsive to those assemblies and the prying resisting member, and a security controller which performs a security procedure in accordance with position of those assemblies and the prying resisting member sensed by the sensors.

Abstract: A reversible electric door lock includes a clutch unit, a dead bolt unit and a handle unit. The clutch unit has an external driving member, two driving plates mounted at two sides of the external driving member, an internal driving member rotatably mounted in the external driving member, and a clutch pin movably disposed in the external driving member between an engaging position to allow synchronous rotation of the external and internal driving members, and a disengaged position to allow idle rotation of the internal driving member. The external driving member is rotated to actuate the dead bolt unit to switch to an unlatched position. The handle unit includes an internal operating handle coupled with one of the driving plates, and an external operating handle coupled with the internal driving member. The reversible electric door lock can be applied to left-hand and right-hand doors.

Abstract: An electronic lock system includes a server unit and an electronic lock device including a control module and a transmission module. The control module outputs a wakeup signal upon receipt of an input signal. The transmission module is to be awaken to an awaken state from a sleep state upon receipt of the wakeup signal, and outputs a confirm signal based on the input signal. The server unit receives a remote signal containing an unlock condition associated with the confirm signal, and outputs an unlock signal to the control module to cause the electronic lock device to operate in an unlock state upon receipt of the unlock signal when the unlock condition is satisfied.

Abstract: An electric lock login setting method includes: a first detection step: using a verification card to detect a detection unit of an electric lock; a learning pairing step: the electric lock stepping into a learning pairing mode so as to communicate an electronic device with the electric lock via a wireless signal, thereby setting pairing between the electronic device with the electric lock; and a second detection step: after setting pairing between the electronic device with the electric lock, using the verification card to detect the detection unit of the electric lock again so as to finishing setting login of the electronic device relative to the electric lock such that the electronic device is authorized to detect the detection unit to activate a control device to unlock the electric lock.

Abstract: An electronic cylinder includes a knob; a cylinder core connected with the knob; a motor having a protrusion block; a clutch unit; a coupler including a chamber receiving the clutch unit and a front portion having a front end face with an opening constituted by an injection channel indented inwardly from the end face and extending from a first point of a periphery confining the end face, an recess indented inwardly from a bottom surface of the injection channel and an outflow channel indented inwardly from the end face and extending from a second point of the periphery, the bottom of the recess being formed with a hole permitting extension of an axle for engaging the clutch unit, a preventing block in a depth of the opening such that after assembly, the end face abuts against the motor; and a waterproof filler hermetically filling the recess.

Abstract: An actuating motor set includes a mounting base; a motor; a transmission set including a worm gear formed with a tooth, wherein two opposite ends of the worm gear respectively defining are a pushing end and a restoring end; and a spring including an engagement part and an abutment part. The engagement part is engaged with the tooth, and an inner diameter of the abutment part is larger than an outer diameter of the tooth. The spring is pushed spirally by the tooth upon rotation of worm gear, and thus moving back and forth on an axial direction of the worm gear. The spring idles when it is moved to the pushing end due to lack of engagement therewith, and the spring also idles when it is moved the restoring end due to lack of engagement therewith.

Abstract: An electronic anti-theft lock mainly internally includes an electromagnetic valve having a vertically movable rod; a locating mechanism that includes a turning plate adapted to shift the whole mechanism inward or outward in multiple steps, a restoring plate adapted to mechanically depress the rod of the electromagnetic valve at an upward extended position, and a stopper adapted to engage with the extended rod of the electromagnetic valve to stop the locating mechanism from moving inward further; and a control circuit adapted to detect a correct IC code of an inserted chip-contained key, and to excite the electromagnetic valve to extend the rod to stop a locking bolt of the locating mechanism from moving inward to open the lock only when an incorrect IC code is detected.
