A novel quick-replaceable sealing trap window structure of a railway vehicle comprises a window frame of the whole window, a fixed window body and a movable window body. The novel quick-replaceable sealing trap window structure is characterized in that a fixed cross beam is welded to the window frame of the whole window and located at the upper end of the fixed window body; a rotary shaft is designed at the upper end of the fixed cross beam; a movable cross beam at the lower end of the movable window body is provided with a rotary shaft groove matched with the rotary shaft on the fixed cross beam at the lower end of the fixed window body; the movable cross beam and the fixed cross beam are movably connected through the rotary shaft; the portion, on the movable window body, of the window frame is provided with a window frame sealing adhesive strip; a cross beam sealing adhesive strip is installed on the side face of the fixed cross beam; the front portion of the movable cross beam is provided with an arc protrusion and a limiting groove; a cross beam cover plate is arranged in front of the matching position of the movable cross beam and the fixed cross beam; an S-shaped spring is arranged between the interior of the cross beam cover plate and the limiting groove of the movable cross beam, and the S-shaped spring is used for positioning the movable window body; and the lower end of the cross beam cover plate is connected with the fixed cross beam. The structure achieves dual sealing; the movable window body is rooted on the window frame, and the risk that the movable window body falls off due to breaking of glass is avoided; and the movable window body is positioned through matching of a pressure spring and the rotary shaft, maintenance is convenient, the maintenance time is shortened, and maintenance cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of operating windows of urban rail vehicles, and includes passenger compartment windows on the standard platforms of urban rail vehicles and light rail and monorail vehicles. In particular, the utility model relates to the sealing performance and quick replacement structure of the rail car window. Background technique [0002] With the progress of society and the development of the times, urban railway vehicles are gradually spreading all over major cities in China, and urban railway windows also adapt to the needs of the market. The safety, fire resistance and comfort requirements of vehicles are getting higher and higher, and the windows of urban railways are also adapting to the needs of the market. In case of fire, it is necessary to meet the needs of emergency ventilation, and the use of movable window structures is required. [0003] In the past, the window and fan structure of the passenger compartme...
