The invention discloses a household portable ladder device capable of automatically lifting. The household portable ladder device capable of automatically lifting comprises basis stairs arranged in bilateral symmetry. Each basis stair is internally provided with a basis cavity with an upward opening. The lower side of each basis cavity is provided with a spline shaft. A spline screw rod extendingupwards into each basis cavity is connected to the interior of the upper end wall of each spline shaft in a rotating fit mode. A thread cavity located in each basis cavity is connected to the corresponding spline screw rod in a screw-thread fit mode. The rear end face of each thread cavity is fixedly connected with a pneumatic supporting rod. The tail end of the rear side of each pneumatic supporting rod is fixedly connected with a pneumatic rod. Connecting rods are hinged to the upper end face of each pneumatic rod in bilateral symmetry. Through the thread cavities in the ladder and up-down reciprocating motion of pneumatic connecting rod devices on the thread cavities, the telescopic ladder achieves the step-by-step telescoping effect and the self-locking effect. A user does not need tomanually stretch the ladder and can control rising and dropping of the telescopic ladder just by pressing a key. The household portable ladder device is wider in scene and people application range, long in service cycle and high in safety reliability, and the possible risk that the ladder device is used in various types of people is avoided.
本发明公开了一种可自动升降的家用便携梯子装置；包括左右对称设置的基础阶梯，基础阶梯内设有开口向上的基础腔，基础腔下侧设有花键轴，花键轴上端壁内转动配合连接有向上延伸至基础腔内的花键螺杆，花键螺杆上螺纹配合连接有位于基础腔内的螺纹腔，螺纹腔后端面固定连接有气动支撑杆，气动支撑杆后侧末端固定连接有气动杆，气动杆上端面左右对称铰接有连接杆，通过置于梯内的螺纹腔及其上的气动连杆装置的上下往复运动，使伸缩梯实现逐梯伸缩的效果，并进行自锁，无需费力进行手动拉伸，只需按动按键即可控制伸缩梯的升降，适用场景、人群更广，使用周期长，安全可靠性高，避免了各类人群在使用中可能存在的风险。
