As preferably, described hanging plate wheel has two at least, the quantity of described grab and position and hanging plate wheel one_to_one corresponding, and grab is positioned at immediately below corresponding hanging plate wheel.Described hanging plate wheel blocks a guide rail for head plate downwards, and described grab upwards snaps in edge at the bottom of the guide rail of described door head plate, namely all blocks a guide rail for head plate up and down, prevents door-plate when being subject to clashing into, and a head plate deviate from by suspension bracket.
As preferably, described grab is U-shaped, and the end of described door head plate is along inserting in the opening of U-shaped.Grab is U-shaped, and processing is simple, directly grab and suspension bracket is fixed during installation.
As preferably, described grab is installed fixing by helicitic texture and described suspension bracket.Suspension bracket can be processed as required and dodge hole, hole is dodged by the end of door head plate along semi-surrounding through this in grab side, and opposite side is adjacent on suspension bracket, fixing both being realized by bolt etc.
As preferably, described lock hook and suspension bracket are wholely set.Add man-hour, utilize suspension bracket once compressing, ensure that the bulk strength of lock hook.
The utility model compared with prior art has following good effect:
Elevator landing door of the present utility model, solve door-plate when being subject to clashing into, the suspension bracket on layer door gear is deviate from, thus the problem causing door-plate to come off, also solve when hanging plate wheel breaks, the problem that suspension bracket comes off simultaneously.This layer of door gear has the advantages that structure is simple, safety performance is high, fabrication and installation are easy, and cost is low.
