Folding stair
The invention provides a folding stair. The folding stair comprises an installing plate, an upper stair combination, a lower stair combination, a steering pedal, a connecting rod combination, a wire rope and a pulley block, wherein the installing plate is fixedly connected with the bottom face of a ceiling and connected with the upper stair combination through a jointed shaft, the upper stair combination and the lower stair combination are connected through a jointed shaft as well, the steering pedal is arranged between the upper stair combination and the lower stair combination, the steeringpedal is rotationally connected with the installing plate by using the connecting rod combination, and the lower stair combination and the connecting rod combination are connected with the pulley block on the installing plate through the wire rope. The folding stair is simple in structure and convenient to use, install and uninstall, a winch is used as a power system, limiting is accurate, the structure is stable, the stair construction time and quality are greatly improved, unnecessary cost is reduced, and the working efficiency is improved.
本发明提供了一种折叠式楼梯，包括安装板、上楼梯组合、下楼梯组合、转向踩踏板、连杆组合、油丝绳和滑轮组，所述的安装板与天花板底面固定连接，所述的安装板使用铰接轴与上楼梯组合连接，上楼梯组合与下楼梯组合之间也通过铰接轴连接，上楼梯组合和下楼梯组合之间设有转向踩踏板，所述的转向踩踏板使用连杆组合与安装板旋转连接，所述的下楼梯组合和连杆组合通过油丝绳与安装板上的滑轮组连接，本发明结构简单，使用方便，安装和拆卸方便，利用卷扬机作为动力系统，限位准确，结构稳固，大大提高了楼梯施工时间及质量的保证，从而减少不必要费用的产生，提高了工作效率。
