[0019] Embodiment:
[0020] As Figure 1As shown, an elevator landing door device includes a door headboard 1. A pair of first hanging door panels 2 and second hanging door panels 3 are symmetrically distributed on the left and right sides and slidably connected to the door headboard 1. Rope pulleys 4 are symmetrically provided at both ends of the door headboard 1. A steel wire rope 5 is wound between the two rope pulleys 4. One end of the steel wire rope 5 is connected to the second hanging door panel 3 through a fixed rope head 51, and the other end of the steel wire rope 5 passes around the two rope pulleys 4 and is connected to the second hanging door panel 3 through an adjustable rope head 52. The first hanging door panel 2 is provided with a fixing bolt 21 that is fixedly connected to the steel wire rope 5.
[0021] The first hanging door panel 2 and the second hanging door panel 3 are respectively fixed to the steel wire rope 5. The fixed rope end 51 is connected to the second hanging door panel 3 through a flat-head screw, and the adjustable rope end 52 is connected to the second hanging door panel 3 through a long screw and a nut. The steel wire rope 5 is used to achieve linkage so that the first hanging door panel 2 and the second hanging door panel 3 can move simultaneously to the center or simultaneously to both ends. A fixed locking hook 6 is provided on the door head panel 1 between the first hanging door panel 2 and the second hanging door panel 3. The second hanging door panel 3 is provided with a landing door lock hook 7 that cooperates with the fixed locking hook 6 to lock. The landing door lock hook 7 is provided with a scale 71.
