[0002] Subway screen doors are sliding door systems installed on both sides of the subway train. They are mainly used to protect passengers from being pinched between the train doors and platform doors before the train stops at the station. They are also helpful in improving the platform environment and the service level of rail transit. Subway screen doors can isolate the noise and pollution between the platform and the train, providing passengers with a more comfortable waiting environment. The glass window part of the subway screen door usually has good light transmittance and dustproof effect, which is convenient for cleaning and maintenance. The subway screen door system usually adopts a modular design, which is convenient for inspection and replacement of parts, and improves the convenience of maintenance.

[0003] If there are a large number of people on the subway, some passengers will lean their backs against the platform screen doors. When the platform screen doors open, the passengers will fall, increasing the risk of accidents. Existing platform screen doors cannot provide timely warnings when they are under pressure.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1-4 As shown, the utility model provides a subway screen door that is easy to maintain, comprising a screen door body 1;

[0022] In this embodiment, a frame-shaped groove 2 is provided on the inner side of the shielding door body 1, a frame-shaped warning member 3 is inserted in the frame-shaped groove 2, elastic pressure-bearing members 4 connected to the inner wall of the frame-shaped groove 2 are installed around the frame-shaped warning member 3, and the frame-shaped warning member 3 is electrically connected to the elastic pressure-bearing member 4;

[0023] The elastic pressure-bearing member 4 includes a pressure-bearing tube 41 .

[0024] In this embodiment, the frame-type warning member 3 includes a frame-type tube 31, which is inserted into the frame-type groove 2, and part of the frame-type tube 31 is exposed to the outside, and a plurality of pressure-bearing tubes 41 are respectively installed around the frame-type tube 31, and an alarm 32 is installed on the outside of the frame-type tube 31, and the alarm 32 is electrically connected to the elastic pressure-bearing member 4. An insertion cavity is provided in the pressure-bearing tube 41, and a pressure sensor 42 is installed in the insertion cavity. An elastic part 43 inserted in the insertion cavity is provided on the pressure-bearing tube 41, and one end of the elastic part 43 away from the pressure-bearing tube 41 is connected to the inner wall of the frame-type groove 2, and the pressure sensor 42 is electrically connected to the alarm 32. The elastic part 43 includes an insert rod 431, an end block 432 and a spring 433. The insert rod 431 is inserted into the insertion cavity, and there is a distance between one end of the insert rod 431 and the pressure sensor 42.
