They serve as vital passageways for evacuating people from within buildings, meeting normal traffic and evacuation requirements. They can withstand the effects of earthquakes and other natural disasters, ensuring safe evacuation. Stairwells are crucial for quickly evacuating people to safe areas. During earthquakes, their structural stability prevents collapse, ensuring a safe escape route within shaky building environments. Even if other parts of the building are damaged, the stairwells provide protection and a means of evacuation.

Part of the elastic snap devices 3 are clamped with the inclined turning device 4, and part of the elastic snap devices 3 are clamped with the plane turning device 5. The inclined turning device 4 includes a fixed plate 41, a rotating plate 42, a connecting plate 43 and a side protection assembly. The fixed plate 41 is fixedly installed on the front side wall of the wall 1, and the rear sides of the plurality of rotating plates 42 are rotatably connected to the upper side of the fixed plate 41 by a rotating shaft. The height of the rotating plate 42 increases successively from left to right, and the connecting plate 43 is rotatably connected to the front side of the rotating plate 42 by a rotating shaft. The side protection assembly is installed between two adjacent rotating plates 42.
[0034] The inclined flipping device 4 and the flat flipping device 5 are quickly deployed to fully shield and protect the upper side of the stair main body 2. At the same time, the elastic snap device 3 allows the inclined flipping device 4 and the flat flipping device 5 to be quickly locked and reinforced with the stair main body 2 after being deployed. The supporting device 6 supports the flipping state and folding state of the inclined flipping device 4 and the flat flipping device 5 to improve stability.
[0035] Specifically, when the device is folded, the rotating plate 42 rotates to drive the connecting plate 43 to move upward and rearward, so that the rotating plate 42 and the connecting plate 43 are both in close contact with the front wall of the wall 1 .
[0036] The rotation of the rotating plate 42 drives the connecting plate 43 to move forward and downward, so that the rotating plate 42 is perpendicular to the front wall of the wall 1, shielding the left side of the stair main body 2, preventing the rubble and debris generated by the shaking of the building during an earthquake from causing harm to the refugees on the stair main body 2, which is conducive to rapid expansion and folding and reduces the space occupied by the equipment.

The arc-shaped rotating plates 33 are rotatably connected in the snap-fit shell 32 through a rotating shaft. The elastic component is installed between the arc-shaped rotating plate 33 and the snap-fit shell 32. The elastic component applies a force to the arc-shaped rotating plate 33 so that the side walls of the two arc-shaped rotating plates 33 close to the central axis of the snap-fit shell 32 are tightly attached to the railing of the stair body 2.
[0042] The elastic component includes an extension block 34 and a tension spring 35.

One end of the tension spring 35 is fixedly mounted in the snap shell 32, and the other end of the tension spring 35 is fixedly mounted on the end of the extension block 34 away from the arc-shaped rotating plate 33.
[0043] The connecting plate 43 moves upward and rearward, driving the vertical plate 31 to move upward and rearward. The vertical plate 31 moves upward and rearward, driving the buckle shell 32 to move upward and rearward. The buckle shell 32 moves upward and rearward, driving the arc-shaped rotating plate 33 to move upward and rearward. The arc-shaped rotating plate 33 leaves the railing of the stair main body 2.
[0044] The connecting plate 43 moves forward and downward, driving the vertical plate 31 to move forward and downward. The vertical plate 31 moves forward and downward, driving the snap shell 32 to move forward and downward. The snap shell 32 moves forward and downward, driving the arc-shaped rotating plate 33 to move forward and downward.
