[0002] The traditional pressure environment passage door is a swing door with the hinge as the rotation axis and the width of the door body as the rotation radius. When people enter and exit the cabin, the door body occupies a large amount of space in the cabin when opening and closing the door, especially for the two connected cabins. The swing doors at both ends occupy a large space when opening and closing the doors, resulting in the inability to place objects in the rotation area of ​​the door body. In addition, the swing doors are equipped with door locks. When the two cabins are depressurized at the same time, a negative pressure environment is easily formed in the passage between the two doors, making it impossible to open the swing doors.

[0023] One end of the suspension rod structure 6 is installed on the sliding sleeve 4-4, and the other end is installed on the door body 5; the suspension rod structure 6 includes: a suspension rod seat 6-1, a suspension rod 6-2 and a suspension door connecting seat 6-3; the suspension rod seat 6-1 is connected to the sliding sleeve 4-4; the suspension door connecting seat 6-3 is rotatably connected to the door body 5; the suspension rod seat 6-1 and the suspension door connecting seat 6-3 are connected through the suspension rod 6-2.

[0024] The working principle of this utility model:

[0025] 1. Check that all components of the sliding door device are in normal working condition and the door is in the closed position;

[0026] 2. When the personnel outside the cabin need to enter the cabin, the personnel entering the cabin hold the outer door handle on the side of the cabin door with both hands and push it toward the door opening side; the upper slider 5-1 on the door body 5 slides on the upper roller guide block 3, the lower roller 8 slides in the lower roller guide groove 9, the sliding sleeve 4-4 in the pulley device 4 slides on the guide rail 4-1, and the arc-shaped transition guide surface on the upper roller guide block 3 and the lower roller guide groove 9 can reduce the resistance of the door body 5 when opening the door; at the same time, the door body 5 is separated from the sealing plate 10-1 when opening the door to avoid the sealing strip 5-2 from being squeezed and damaged; when the cabin door is pushed to the maximum opening, the door body 5 is impacted and contacted with the limit buffer 1 by the thrust inertia, and the hydraulic buffer function and the rubber head on the limit buffer 1 make the door body 5 stop at the maximum position. At this time, after entering the cabin, the personnel hold the inner door handle on the other side of the cabin door and pull it to the closed state. The closed state is determined by the installation position of the limiter 7. At this time, the personnel complete the cabin entry work.

[0027] 3. When the people in the cabin need to leave the cabin, the same principle applies.

[0028] The protection scope of the present utility model is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
