The folding elevator comprises a folding ladder and a mounting frame used for hanging the folding ladder to the top of the interior of a containing cabin, a folding frame of the folding ladder is formed by hinging a long connecting rod pair in the middle and short connecting rod pairs at the two ends, and the middle of each long connecting rod pair is hinged to the end of each short connecting rod pair through a pin shaft; a slide way is arranged on the mounting frame, the slide way comprises a horizontal first slide way and an inclined second slide way, a first pin shaft between the long connecting rod pair is in sliding connection with the slide way through a first connecting rod, and the first connecting rod is connected with a driving mechanism; a second pin shaft located at the top of the folding ladder and between the short connecting rod pairs is rotationally connected with the mounting frame through a second connecting rod and a third connecting rod in sequence; the driving mechanism pushes the first connecting rod to slide along the slide way, the second connecting rod and the third connecting rod are driven by the first connecting rod to push the folding ladder to slide out of the containing bin and rotate and unfold, and one-step unfolding and folding of the folding ladder can be achieved by arranging the three-connecting-rod mechanism, cooperating with the preset slide way and controlling the driving mechanism to operate.

    本发明公开了一种折叠升降梯,包括折叠梯、用于将折叠梯挂接在容纳舱内部顶部的安装架,所述折叠梯的折叠架由中部的长连杆对、两端的短连杆对铰接形成,每组长连杆对的中部,每组短连杆对的端部通过销轴铰接,所述安装架上设有滑道,所述滑道包括水平的第一滑道、倾斜的第二滑道,所述长连杆对之间的第一销轴通过第一连杆和滑道滑动连接,第一连杆连接驱动机构;位于折叠梯顶部的、短连杆对之间的第二销轴依次通过第二连杆、第三连杆和安装架转动连接;驱动机构推动第一连杆沿滑道滑动,第二连杆、第三连杆由第一连杆带动,推动折叠梯滑出容纳仓并转动展开,通过设置三连杆机构,配合预设滑道,控制驱动机构运作,即可实现折叠梯一步展开,折叠。
