Lock state reminding device

Abstract

The invention discloses a lock state reminding device which comprises a clutch assembly, a left optocoupler, a right optocoupler, a right optocoupler swing plate assembly and a left optocoupler swing plate assembly. The clutch assembly comprises a rotating clutch wheel and a sliding block guide base. The rotating clutch wheel is rotatably arranged on the periphery of the outer side of the sliding block guide base in a sleeving mode. The distance from the outer side wall of the rotating clutch wheel to the circle center of the sliding block guide base is gradually decreased. The left optocoupler and the left optocoupler swing plate assembly are arranged on the left side of the clutch assembly, the right end of the left optocoupler swing plate assembly makes contact with the outer side wall of the rotating clutch wheel, and the left optocoupler swing plate assembly can be rotated in and out of the left optocoupler. The right optocoupler and the right optocoupler swing plate assembly are arranged on the right side of the clutch assembly, the left end of the right optocoupler swing plate assembly makes contact with the outer side wall of the rotating clutch wheel, and the right optocoupler swing plate assembly can be rotated in and out of the right optocoupler. The lock state reminding device is simple and compact in structure and can carry out state adjustment accurately in time.

Description

technical field [0001] The invention belongs to the technical field of lock manufacturing, and in particular relates to a lock state reminding device.
