SAFE DOOR LOCK WITH SERVO MOTOR OPERATED CAM
Abstract:
A safe door lock with a servo motor (34) operated cam (33) is described. A retracting lever (26) is pivotally secured to the locking bolt (15) and is displaced on a pivot connection with the bolt (15) by the cam (33). The position of the cam (33) and the bolt (15) are detected by microswitches. When the retracting lever (26) is in a locking position, the bolt (15) cannot be retracted within the lock housing (11). The cam (33) is operated by a servo motor (34) and locked in position by the gear train which includes a worm gear (64, 67). The locking bolt (15) may be a slam bolt having a spring (50) biased latch (16) which slides therewith or the locking bolt (15) may be a deadbolt when the lock is used with a boltwork system of a vault door.
Abstract(Chinese):

描述了具有伺服电机（34）操作的凸轮（33）的安全门锁。 缩回杆（26）枢转地固定到锁定螺栓（15）上并且通过凸轮（33）与螺栓（15）枢转连接而移位。 通过微动开关检测凸轮（33）和螺栓（15）的位置。 当缩回杆（26）处于锁定位置时，螺栓（15）不能缩回锁定壳体（11）内。 凸轮（33）由伺服电机（34）操作，并由包括蜗轮（64,67）的齿轮系锁定在适当位置。 锁定螺栓（15）可以是具有弹簧（50）偏置的闩锁（16）的撞栓，当弹簧（50）与闩锁（16）一起滑动时，锁定螺栓（15）可以是闩锁，当锁与拱门的螺栓系统一起使用时。
