Abstract

A strike lock includes an upper frame, a lower frame, a door position detector, a door position detecting spring, an electromagnetic tube, a detecting switch assembly, a buckle assembly, a press assembly, and a lock assembly. The detecting switching assembly is formed by a door position detecting switch, a substrate, and an electromagnetic tube detecting switch. The buckle assembly is formed by a buckle, a buckling spring, and a straight screw. The press assembly is formed by a positioning plate, a press unit, a pressing spring, and a positioning screw. The lock assembly is formed by a lock, a support unit, and a locking spring. The operation of the strike lock is that the electromagnetic tube moves transversally to push the buckle assembly, when the press assembly can move downwards to buckle the buckle assembly, the locking spring and the lock are free to move to have the object of door unlocking. When the press assembly cannot move downwards to buckle the buckle assembly, the locking spring and the lock are locked by the press assembly to have the object of door locking. The operation of the strike lock is that when the electromagnetic tube is excited to move the buckle assembly transversally, the press assembly is able to move downwards and the lock is free to move so as to have the object of an electric lock. Through changing the installation direction of the buckle, the functions of unlocking the door under power supplying or power interruption are switched.
