[0030] A window 7 is arranged at the other side of the carriage 1, a horizontal sliding push-pull window 8 and a vertical rotating outer push window are installed at the window 7. The push-pull window 8 comprises an aluminum alloy frame and glass installed on the movable frame, and the push-pull window 8 can be opened at each position through window sash sliding, and the glass facilitates observation from the outside of the carriage 1 to the inside of the carriage 1. When used as a dining car, the push-pull window 8 is closed, and sanitation can be ensured.

[0031] The outer push window is located outside the push-pull window 8, and the outer push window comprises an upper outer push window 9 and a lower outer push window 10, the upper outer push window 9 is rotatably connected with the upper end of the window 7, and the lower outer push window 10 is rotatably connected with the lower end of the window 7.

[0032] The upper and lower push-out windows 9 and 10 are vertically rotated, the outer side material of the upper and lower push-out windows 9 and 10 is the same as the outer wall material of the carriage 1, and the coating color is consistent, so that the upper and lower push-out windows 9 and 10 have good consistency, integrity and aesthetic appearance when the push-out windows are closed; and the outer side line of the carriage 1 is smooth, and the wind resistance is small.

[0033] The outer side surface area of the upper push-out window 9 is greater than that of the lower push-out window 10, that is, the horizontal size of the upper and lower push-out windows 9 and 10 is the same, and the vertical size of the upper push-out window 9 is greater than that of the lower push-out window 10.

[0036] The inner sides of the horizontal two ends of the upper push-out window 9 and the inner sides of the horizontal two ends of the lower push-out window 10 are connected to the automatic telescopic rods 11; there are four automatic telescopic rods 11.

[0037] When the upper push-out window 9 is opened, the straight plate part thereof is in a horizontal state and can be used for sun-shading and rain-shielding. When the lower push-out window 10 is opened, it is in a horizontal state and is butted against the outer side of the window sill of the window 7, and can be used for placing articles, such as placing food on the upper side of the lower push-out window 10 when taking food.

[0038] In some embodiments, sealing strips can be arranged at the edges of the upper and lower push-out windows 9 and 10, and the lower edge of the upper push-out window 9 and the upper edge of the lower push-out window 10 abut against each other when the push-out windows are closed, so as to further improve the sealing performance of the push-out windows when they are closed. On the basis of the sealing of the double-layer window, the rotating push-out windows have better sealing performance than the horizontally sliding sliding windows 8.

[0039] In order to improve the stability of the upper and lower push-out windows 9 and 10 when they are closed, in the embodiment, the inner sides of the ends of the upper push-out window 9 and the lower push-out window 10 away from the rotating ends thereof are connected to the positioning plates 12, and the positioning plates 12 are provided with pin holes 13. The positioning plates 12 are arranged at the inner sides of the corner parts of the upper and lower push-out windows 9 and 10, and the number of the positioning plates 12 is four.

[0040] The trailer is provided with two limiting plates 16, one side of the limiting plate 16 is connected with two pin columns 18 respectively matched with the inner pin holes 13 of the upper and lower sliding windows 9 and 10; the number of the pin columns 18 is four in total; the inner side of the window 7 is provided with four positioning holes 19 matched with the pin columns 18, wherein the front and rear side walls of the window 7 are respectively provided with two upper and lower positioning holes 19 corresponding to each other.

[0041] When the upper and lower sliding windows 9 and 10 are closed, the pin holes 13 on the inner side positioning plates 12 at the corners are respectively matched with the upper and lower positioning holes 19, and the limiting plate 16 and the pin column 18 are held to make the pin column 18 pass through the pin hole 13 of the limiting plate 12 and enter the positioning hole 19, so as to realize the positioning of the upper and lower sliding windows 9 and 10 after being closed.

[0042] In order to avoid the limiting plate 16 and the pin column 18 from falling off during the forming of the trailer, the inner side of the window 7 is threadedly connected with a stud 14, the front and rear side walls of the window 7 are respectively provided with inner threaded holes threadedly connected with the stud 14, and the inner threaded holes are located between the upper and lower positioning holes 19. The outer end of the stud 14 is connected with a hand wheel 15, so as to facilitate the rotation of the stud 14. The stud 14 passes through the middle part of the limiting plate 16, and the middle part of the limiting plate 16 is provided with a through hole 17 for the stud 14 to pass through, and the inner diameter of the through hole 17 is greater than the maximum outer diameter of the stud 14.

[0043] The rotation of the hand wheel 15 makes the stud 14 rotate; when the stud 14 moves towards the inner end of the inner threaded hole, the hand wheel 15 makes the limiting plate 16 and the pin column 18 move towards the positioning hole 19, and the hand wheel 15 limits the limiting plate 16 and the pin column 18, so as to avoid the pin column 18 from falling off. When the stud 14 moves outwards from the inner threaded hole, the limiting plate 16 and the pin column 18 can be taken out and separated from the positioning hole 19 and the positioning plate 12, and the separation does not affect the opening and closing of the upper and lower sliding windows 9 and 10.
