After receiving the signal, the platform screen door control system will control the first sliding door 201 and the second sliding door 202 to contract towards the inside of the fixed door 1, thereby controlling the opening of the platform screen door, and then pedestrians pass through the platform screen door in turn.
[0023] As a technical optimization solution of the present utility model, the telescopic structure 3 includes a sliding groove 301. A sliding groove 301 is provided at the edge of the first sliding door 201. A buffer plate 302 is slidably connected inside the sliding groove 301. Two springs 304 are fixedly connected between the inner wall of the sliding groove 301 and the buffer plate 302. Two guide rods 303 are fixedly connected to the inner wall of the sliding groove 301. The guide rods 303 penetrate through the springs 304. The buffer plate 302 is slidably connected between the two guide rods 303. If the hair or clothes are clamped due to pedestrians not passing through the shielding door in time, since the buffer plate 302 is provided on the first sliding door 201 and the buffer plate 302 slides in the sliding groove 301 opened on the first sliding door 201, when pulling the clothes or hair outwards, the buffer plate 302 is driven to contract towards the inside of the sliding groove 301 along the two guide rods 303, thereby increasing the gap between the buffer plate 302 and the rubber pad 402, so as to facilitate the extraction of the hair or clothes from between the first sliding door 201 and the second sliding door 202. At the same time, since the upper and lower ends of the edge of the first sliding door 201 are always engaged in the docking groove 401, the closing state of the shielding door is not affected during the process of extracting the clothes, and the flexibility is strong.
[0024] As a technical optimization solution of the present utility model, a maintenance plate 305 is installed on the first sliding door 201.
