ELECTRIC STRIKE LOCK

摘要

An electric strike lock has a strike body, a latch having a latch bolt and a deadlatch, a keeper having a stop block to abut against the deadlatch, and an adjusting section having an elliptical adjusting hole corresponding to a screw hole on the keeper and an adjusting piece fitting a shape of the elliptical adjusting hole and having an eccentric through hole for an adjusting screw to pass through and to be screwed to the screw hole. The keeper further combined with a solenoid which has a movable rod passing through the keeper and engaging the stop block, and the elliptical adjusting hole has its major axis arranged in the same direction as an axis of the solenoid. By changing the placement of the adjusting piece, the positions of the stop block and the deadlatch can be altered to adjust the strike lock into a fail-safe or a fail-secure strike lock.

主权项

1. An electric strike lock comprising:
a strike body engaged with a cover plate; a latch having a latch bolt and a deadlatch, said latch engaging a spring and being disposed inside the strike body together with said spring; a keeper having a screw hole and a stop block in correspondence to the deadlatch and connecting to a solenoid which has a movable rod passing through the keeper and engaging the stop block; whereby the stop block is pushed by the solenoid and moves between a position blocking the latch and a position unblocking the latch; and an adjusting section including an elliptical adjusting hole on the cover plate in correspondence to the screw hole, and an elliptical adjusting piece corresponding to the adjusting hole, said adjusting piece having an eccentric through hole for an adjusting screw to pass through and to be screwed with the screw hole, a major axis of said adjusting hole arranged in the same direction as an axis of the solenoid; whereby the eccentric through hole enables the adjusting piece to be disposed in two different positions by rotating 180° for adjusting the electric strike lock to be fail-safe or fail-secure.
