A fall-proof telescopic plate for subway platform screen doors

Abstract

The present invention discloses a fall-proof telescopic plate for a subway platform screen door, which comprises a door assembly. The door assembly includes a platform screen door, a subway door, a slide rail and a gap. The platform screen door and the subway door are placed parallel to each other, and there is a gap in the middle. The subway door is slidably connected inside the slide rail, and a fall-proof assembly is provided on the side wall of the slide rail. The fall-proof assembly includes a chute assembly, a slider, a telescopic assembly, a rotating sling and a hook. The side end face of the slide rail vertically penetrates through the chute assembly. The slider is slidably connected inside the chute assembly. One end of the slider is fixedly connected to the telescopic assembly, and the other end of the telescopic assembly is fixedly connected to the rotating sling. The inner wall of the rotating sling is clamped with the hook, and the hook is fixedly connected to the side wall of the platform screen door. When the platform screen door is opened to both sides, the hook is driven to pull the left telescopic plate and the right telescopic plate to both sides, so that a plurality of telescopic plates are unfolded. And because the chute is an inclined plane downward inside, if there are small objects falling in, they can roll down along the slope to avoid falling to the bottom of the slide rail.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-5, the present invention provides a technical solution: an anti-fall telescopic plate for a subway platform screen door, which includes a door assembly 1. The door assembly 1 includes a platform screen door 11, a subway door 12, a slide rail 13 and a gap 14. The platform screen door 11 and the subway door 12 are placed parallel to each other, and there is a gap 14 in the middle. The subway door 12 is slidably connected inside the slide rail 13. An anti-fall assembly 2 is provided on the side wall of the slide rail 13. The anti-fall assembly 2 includes a chute assembly 20, a slider 22, a telescopic assembly 23, a rotating sling 24 and a hook 25. The side end face of the slide rail 13 vertically penetrates the chute assembly 20. The slider 22 is slidably connected inside the chute assembly 20. One end of the telescopic assembly 23 is fixedly connected to the slider 22, and the other end of the telescopic assembly 23 is fixedly connected to the rotating sling 24. The inner wall of the rotating sling 24 is clamped with the hook 25, and the hook 25 is fixedly connected to the side wall of the platform screen door 11.

[0018] The chute assembly 20 includes a chute 201, a stop chute 202 and a placement groove 203. The side wall of the slide rail 13 vertically penetrates the chute 201. The stop chute 202 penetrates both side walls of the chute 201. The inner wall of the chute 201 extends through the placement groove 203, and the slider 22 is slidably connected inside the placement groove 203.

[0019] The chute 201 is a downwardly concave inverted "V" - shaped groove, the placement groove 203 is a spherical groove, the stop chute 202 is a three - quarter circular hole mechanism, and the inner wall is fixedly connected with an anti - slip sheet made of rubber material.

[0020] The telescopic assembly 23 includes a left telescopic plate 230, a right telescopic plate 231 and louvers 232. The left telescopic plate 230 and the right telescopic plate 231 are connected end to end by the louvers 232, and the connection positions on one side end face of the left telescopic plate 230 and the right telescopic plate 231 are fixedly connected with the slider 22 at intervals. The front and rear ends of the other side end face of the left telescopic plate 230 and the right telescopic plate 231 are fixedly connected with the rotating sling 24.
