[0030] Working principle:

[0031] The high airtightness movable window on the train has a window frame 1 installed on the train. When the window needs to be opened after the train stops at the station, the handle 6 is held with one hand, and the connecting column 12 and the push block 13 are driven to move through the adjustment plate 8 to release the support for the positioning column 16. At the same time, the adjustment plate 8 compresses the fixing spring 9, and the support spring 18 pushes the limit ring 17 and the positioning column 16 to move, so that the positioning column 16 is separated from the window frame 1. The position of the movable window 3 can be adjusted by the handle 6. The movable window 3 is opened during the train stops at the platform to allow air to flow in the train.

[0032] When the position adjustment of the movable window 3 is completed, the adjusting plate 8 is released, and the fixing spring 9 pushes the adjusting plate 8 to move. The adjusting plate 8 drives the pushing block 13 to move through the connecting column 12. The pushing block 13 supports the positioning column 16, pushes the positioning column 16 to move, and pushes one end of the positioning column 16 into the positioning holes on both sides of the window frame 1, thereby fixing the position of the movable window 3. During the travel of the train, the movable window 3 always remains in a closed state.
