The utility model provides an
elevator landing door mechanism which comprises an upper sill
assembly, a lower sill sliding rail, a first landing door plate and a second landing door plate. The first landing door plate and the second landing door plate are installed between the upper sill
assembly and the lower sill sliding rail in a sliding mode. The upper sill
assembly comprises an upper
sill plate, a first displacement frame, a second displacement frame and a driving part, the first displacement frame and the second displacement frame are installed on the upper
sill plate in a sliding mode, the driving part drives the first displacement frame and the second displacement frame to synchronously move in the opposite or opposite directions, a first layer door plate is fixedly installed at the lower end of the first displacement frame, and a second layer door plate is fixedly installed at the lower end of the second displacement frame. An in-place switch on the support is used for detecting whether the first-layer door plate and the second-layer door plate are closed in place or not, and if a stick or a glass article is clamped between the first-layer door plate and the second-layer door plate, the first-layer door plate and the second-layer door plate are prevented from being closed in place; the
photoelectric sensor detects whether the groove between the first layer door plate and the second layer door plate is blocked by articles, and if articles such as ropes are clamped in the groove,
light source receiving of the
photoelectric sensor can be blocked.
