The invention belongs to the technical field of foldable stairs, and discloses a foldable stair for connecting a cabin and a deck, the foldable stair comprises a support plate frame, two breast boards are fixedly connected to the two ends of the support plate frame, and a T-shaped groove is formed in the inner wall of the bottom end of each breast board; the pull handles at the two ends of the bottom plate are manually pulled to drive the sliding rods arranged on the floors to move downwards, so that the groove rods connected through the inclined plates are driven to move, the ladder plates are driven to move out of the inner walls of the ladder grooves, and the first springs will not be squeezed any more and will rebound immediately to drive the U-shaped rubber plates to move upwards; when a person steps on the stair formed by a floor and a stair plate, generated extrusion force and shaking can drive the chain to synchronously move up and down to be in a loose and tight state, so that the corrugated pipe is driven to generate gas, each suction cup conducts negative pressure adsorption on the ground around the conical plate, and two symmetrical clamping covers connected through a T-shaped clamping plate are pushed to move in a T-shaped groove; and the whole stabilizing part can be clamped and covered in the fixing part.

    本发明属于可折叠楼梯技术领域,且公开了一种船舱与甲板连接用的可折叠楼梯,包括支板架,支板架的两端上均固定连接有两个栏板,每个栏板底端内壁中均设有T形槽;通过人工拉住底板两端上的拉柄可带动每个楼板上设置的滑杆进行下移,由此带动由斜板连接的槽杆进行移动,带动梯板移动出梯槽内壁,弹簧一就不会再受到挤压,会立刻回弹带动每个U形胶板上移,当底板被拉动接触到地面时,人工踩踏由楼板和梯板构成的楼梯时,所产生的挤压力以及晃动会带动锁链同步上下移动呈现松、紧状态,由此带动波纹管产生气体,使每个吸盘均对圆锥板周边地面进行负压吸附,推动由T形卡板连接的两个对称卡罩在T形槽中移动,可将整个稳固部卡罩在其内部。
