MALFUNCTION BY IMPACT PREVENTING DEVICE OF THE LOCKING DEVICE

摘要

The device for preventing abnormal operation of card-type magnetic locking device when the outside shock is given, comprises a locking plate (1) with a plurality of holes; an actuator (3) being movable near the plate (1) and having a plurality of openings (32) opposed to the holes; a module plate (2) for fixing the plate (1); a weight (34) near the actuator; an interlocking latch (36) on the module plate at the passage for passing the actuator. When the weight is displaced by the outside shock, the weight is interlocked with the latch and the actuator is not able to descend.
