Abstract

The invention relates to a door lock structure for an external elevator floor door. The door lock structure is mounted above an elevator door, and comprises a left hanging plate and a door lock fixing plate which are mounted on a door head, wherein a lock hook assembly is arranged on the door lock fixing plate, and comprises a rotating shaft which is rotationally connected with the door lock fixing plate; a lock hook is arranged on the rotating shaft; a connecting plate is arranged at the front end of the lock hook; a first movable limiting plate is arranged at the rear end of the lock hook; a first fixed limiting plate is arranged on the door lock fixing plate; the first movable limiting plate is arranged on the outer side of the first fixed limiting plate; a positioning bulge is arranged on the first movable limiting plate; a first lock groove plate used for being matched with the lock hook is arranged on the left hanging plate and provided with a slope; and the slope is matched with the inclined surface at the front end of the lock hook. Through the matching between the first fixed limiting plate and the first movable limiting plate as well as through arrangement of the positioning bulge, the lock hook can be rapidly mounted and positioned. Accordingly, the mounting is convenient and rapid, a lot of time is saved, the mounting efficiency is improved, and the safety performance is guaranteed.

Description

technical field [0001] The invention relates to the elevator production and manufacturing industry, in particular to a door lock structure for the outer door of an elevator floor.
