Including shield door and shielding door frame, the structure is partly surrounded in fixed setting on the lateral wall of shielding door frame, outer corridor inner with partly surround structure fixed connection, interior corridor nestification in outer corridor, identical hard pressing rubber frame to the side of fixed set port shape and the train onits outer port. Partly surround the structural drive arrangement who acts on outer corridor that is provided with for the corridor outwards moves to the hard pressing rubber frame outside port and train surface contact and inwards moves the return in the drive, drive arrangement is controlled by the controller, and the controller is received by outdoor temperature value and shield door switchingsignal that temperature sen
