[0023] Among them, one end of the groove guide rail 12 is a bent section and the other end is a straight section. The straight section of the groove guide rail 12 is arranged parallel to the front side of the door carrying arm 7, and the bent section of the groove guide rail 12 is bent in the direction away from the door carrying arm 7.

[0024] The mounting frame 2 is fixedly installed inside the carriage 19, and a door frame 20 is embedded on the surface of the carriage 19. The door-carrying crank arm 7 can extend from the hole of the door frame 20 to the outside of the carriage 19, and the door leaf 1 is closed in the door frame 20 by the plug cover of the door-carrying crank arm 7. By setting a groove guide rail 12, the door-carrying crank arm 7 slides along the groove guide rail 12 through the roller 13, so as to realize the movement of the door leaf 1 in the left and right directions and the front and back directions, thereby achieving the plug opening and closing effect.

[0025] The inner surface of the door leaf 1 is fixedly mounted with a first sealing strip 21 and a second sealing strip 22, an observation window is embedded in the surface of the door leaf 1, a lock 23 is embedded inside the door leaf 1, a limiting hole is provided on the inner wall of the door frame 20, and the telescopic end of the lock 23 can be inserted into the limiting hole.
