Two-door-leaf manual folding car door device for elevator

Abstract

The invention relates to a two-door-leaf manual folding car door device for an elevator. The two-door-leaf manual folding car door device comprises a car door, wherein the car door is composed of a hanging wheel door and a rotating shaft door which are arranged side by side and hinged to each other; a door hanging rail is arranged at the upper end of a car entrance / exit; the upper end of the outer side of the rotating shaft door is rotationally connected with the door hanging rail through an upper door shaft; the lower end of the outer side of the rotating shaft door is rotationally connected with a sill sliding groove through a lower door shaft; a door hanging wheel is arranged at the upper end of the outer side of the hanging wheel door; a guiding shaft is fixed at the lower end of the outer side of the hanging wheel door; an electromagnetic lock and a door closing in-place verification switch are mounted at the bottom end of the front side surface of a door head beam; an electromagnetic lock suction plate is mounted on the front side surface of the upper end of the rotating shaft door; after the door is closed in place, the door closing in-place verification switch is switched on, the electromagnetic lock and the electromagnetic lock suction plate attract mutually, and safety loop of the elevator is switched on, so that the elevator can run, and high safety and reliability are realized. According to the two-door-leaf manual folding car door device, the hanging wheel door and the rotating shaft door are hinged through a hinge, so that the folding door is formed and mounted at the position of the car entrance / exit, therefore, shearing and squeezing risks during running of the elevator car are prevented.

Description

technical field [0001] The invention relates to a household elevator assembly, in particular to an elevator double-leaf manual folding car door device. Background technique [0002] At present, in order to maximize the indoor space, users have smaller and smaller requirements for the size of the hoistway of the home elevator, which makes it difficult to realize the design of the automatic door opener, and can only be designed as a manual door type. However, most of these designs only have hall doors and no car doors. Although the elevator speed of this type of elevator is usually low (the national standard stipulates that the maximum is 0.4m / s), there are still problems of shearing and extrusion during elevator operation. Security risks. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-leaf manual folding car door device for an elevator, which can effectively prevent the danger of shearing and extrusion ...
