Abstract: A solenoid-operated electric lock includes a lock casing, a catch movably mounted on the lock casing, and a solenoid received in the lock casing. The solenoid includes a housing, a first magnet and a second magnet respectively mounted on two ends of the housing, and a movable iron core disposed in the housing. A first bolt is disposed on the movable iron core. A wire coil is wound around the movable iron core. The locking casing receives a driving member, a first gearing device, and a second gearing device. The driving member is selectively pressed by the first bolt. The first gearing device is engaged with the driving member and has a rotatable cylinder mounted therein. The second gearing device has a lever selectively abutting against the catch. The lever has an abutting portion formed thereon for releasably connecting with an outer periphery of the rotatable cylinder.

Abstract: An electromagnetic lock comprises: a body combined with a retaining frame by using locking studs and retaining screws; one side of the retaining frame being installed with a trigger receiving box; and an absorption plate combined to a supporting frame; two metal rings being installed in the absorption plate; the absorption plate having locking screws; wherein in installation, for aligning the body and the absorption plate, adjusting screws are installed between the absorption plate and the supporting frame. The supporting frame has screw holes for receiving the adjusting screws; one side of the supporting frame has two magnetic holes for receiving magnets; a magnet protection sheet are installed at lower side of the magnets; and a small screw serves to lock the protection sheet to the supporting frame. The trigger can be hidden so as to occupy a small space and the installation work is easy.

Abstract: A magnetic lock comprises an actuation portion; a positioning seat having a slot at a rear end thereof for receiving the actuation portion and a circuit board; a tongue embedded at the slot at the lower end of the positioning seat and being fixed to the connecting sheet; the tongue being movable within the positioning seat; a retaining seat having a displace unit; a core embedded into the slot of the retaining seat and to combine with the displace unit; thereby the movable post, driving sheet, connecting sheet and tongue being interconnected. The magnetic lock is suitable for doors of various specifications. Furthermore, the magnetic lock has an open mode in power-on state and a close-mode in power-off state. Moreover, a pin serves to achieve the object of function setting modes. The magnetic lock has the functions of a mechanical lock and an electronic lock.

Abstract: An electromagnetic lock device includes a receptacle, a deadbolt slidably engaged in the receptacle and extendible out of the receptacle, for locking a door panel to a door frame, a shaft attached to one end of the deadbolt. A housing is attached to the receptacle, and includes a plunger core slidably received in a coil and actuatable by the coil and having a pin. An elbow includes an arm pivotally secured to the receptacle, an opening formed in an intermediate connecting portion to slidably receive the pin, and another arm having an oblong hole to slidably receive the shaft, and to allow the deadbolt to be forced in and out of the receptacle by the plunger core via the elbow. A spring member may bias the plunger core out of the housing, when the coil is not energized.
