Abstract
A lock mechanism includes a plug assembly, a transmission spindle, a bush and a latchbolt assembly. The transmission spindle is coupled to the plug assembly. The bush and the transmission spindle are coupled as one piece to allow the transmission spindle to drive the bush rotate. The latchbolt assembly includes a latchbolt and an actuation element having an actuation hole. The bush, movably accommodated in the actuation hole, is provided to drive the actuation element in swinging movement to move the latchbolt. Because of the bush movably accommodated in the actuation hole, the latchbolt assembly can move toward or away from the plug assembly and the lock mechanism can be mounted on doors having different thicknesses.
