EMU side airtight ventilation window

Abstract

The invention belongs to the technical field of windows of motor train units and discloses an airtight ventilation window on sides of a motor train unit. The airtight ventilation window comprises an outer frame installed on a train body. A movable-sash window is installed in the outer frame, one end of the movable-sash window is hinged to the outer frame, and the other end of the movable-sash window is provided with a movable-sash handle used for being connected with the outer frame. The openable movable-sash window is adopted, the movable-sash window can be rotated by 180 degrees, a space in an automobile is not occupied after the window is opened, and thus ventilation or escape can be realized; the safety inside and outside the train can be further guaranteed under the ventilation state through the arrangement of a protective screen, thus the situation that passengers throw foreign objects and the safety of adjacent lines is influenced is avoided, and the safety of the passengers is guaranteed; the movable-sash window is positioned through a movable-sash window positioning device; the movable-sash window adopts a sealing way of double sealing rubber strips, a slight compression function is fulfilled when a window sash lock is locked, the airtightness between an inner frame and the outer frame, that is, between the movable-sash window and the outer frame can be guaranteed through the double-layer or multi-layer sealing rubber strips, and therefore the use requirement is met.

Description

technical field [0001] The invention relates to the technical field of vehicle windows of multiple train units, in particular to an airtight ventilation window on the side of train trains. Background technique [0002] The EMU is a high-speed train with a speed of more than 300 kilometers per hour. In order to ensure the comfort of passengers, the passenger rooms of the existing EMU are all fixed windows with airtight structure. When the train power supply or air conditioner fails, the passenger room must be completed by opening the door. ventilation. The opening of the car door affects the traction of the train, and because the door-opening operation has potential safety hazards, the door-opening operation cannot be performed. For example, if the air conditioning system fails, only the ventilator is needed, but the windows are closed, and the EMU cannot continue to run after the doors are opened. Therefore be badly in need of a kind of not only can realize ventilating, th...
