Abstract: A door lock device is worked in cooperate with a latch bolt, and includes a solenoid device engaged in a housing, a catch member pivotally attached to the housing with a spindle, two arms connected between the catch member and the spindle, and the solenoid device includes a shaft slidably engaged in a receptacle, and the shaft includes an upper end portion extendible upwardly beyond the receptacle and a lower end portion extendible downwardly beyond the receptacle, and the solenoid device includes two anchors on the upper end portion for selectively engaging with the upper arm, and two stops on the lower end portion for selectively engaging with the lower arm of the latch device, and for allowing the catch member to be evenly engaged with the latch bolt.

Abstract: An exit lock assembly is provided. The exit lock assembly comprises a base, two doorstops, two first links, two second links, two solenoid valves and a cover. The base and the cover are combined to form a receiving space to receive the two doorstops, the two first links, the two second links and the two solenoid valves. The doorstops are closed in an initial position when the solenoid valves are not energized. When the solenoid valves are energized, two plugs of the two solenoid valves move along the direction opposite a central area and drive two fifth ends of the two second links, two fourth ends of the two second links thus get away from the third ends of the first links, and the second end of the doorstop moves down and makes the doorstops in an open status.

Abstract: A lock device includes a tongue engaged in a housing, an anchoring device slidably disposed in the housing and movable with a moving device, the includes two sides each having a latch socket and an anchoring member, when one side of the anchoring device is directed toward the tongue, the lock device is locked when the moving device is turned off, and the lock device is locked when the moving device is turned on and when the other side of the anchoring device is directed toward the tongue, such that the electric lock device is adjustable and operatable when the electromagnetic mechanism of the moving device is either switched on or switched off.

Abstract: A lock device includes a tongue slidably engaged with a housing and extendible out of the housing, an anchoring device slidably disposed in the housing and having two anchoring members for selectively aligning with the tongue and having a compartment formed between the anchoring members, and a moving device for moving the anchoring device relative to the housing to selectively align either of the anchoring members with the tongue and for preventing the tongue from being engaged into the compartment of the anchoring device. The moving device includes an electromagnetic mechanism coupled to the anchoring device for moving the anchoring device relative to the housing.
