Description

Technical Field

[0001] The utility model relates to the technical field of subway shielding doors, in particular to an anti-pinch structure for subway shielding doors. Background Art

[0002] The subway platform is a place with many people. When the train enters the station and stops, the screen door opens in both directions and passengers enter one after another. After the train leaves, the screen door closes. The screen door is a glass curtain wall on the platform that surrounds the subway platform and the boarding and alighting space of the train. When the train arrives, the electric door on the glass curtain wall is opened for passengers to get on and off the train. When passengers get on and off the train, backpacks are easily caught by the closed screen door, which is inconvenient to remove.
