The invention provides a retractable folding ladder. The retractable folding ladder comprises a ladder supporting part, ladder parts and supporting parts. The ladder parts are mounted on the side faceof the ladder supporting part. The supporting parts are mounted below the ladder parts. Each ladder part comprises a ladder supporting plate A, a rotary shaft B, a ladder supporting plate B, a laddersupporting plate A fixing base, a synchronous belt and a connecting plate, wherein the synchronous belt is mounted on synchronous wheels B; the rotary shaft B is rotatably mounted in a circular holeof the connecting plate; and the connecting plate is fixedly connected with the ladder supporting plate B. The retractable folding ladder is composed of the multiple identical ladder parts. Thus, different quantities of ladder parts can be arranged to form different lengths of the ladders, and the requirements for different lengths of the ladders can be met. Through the foldable ladder parts, theretractable folding ladder can be folded and unfolded, can effectively reduce the occupied area and is convenient to take, store and transport.
一种可收缩折叠式扶梯，包括：扶梯支撑部分、扶梯部分和支撑部分，所述扶梯部分安装在扶梯支撑部分侧面；所述支撑部分安装在扶梯部分下面；所述的扶梯部分包括扶梯支撑板A、同步轮B、转轴B、扶梯支撑板B、扶梯支撑板A固定座、同步带、连接板，所述同步带安装在同步轮B上；转轴B转动安装在连接板的圆孔里；连接板与扶梯支撑板B固定连接；通本发明的扶梯部分由多个相同部分构成，因此可以根据不同的扶梯长度来设置不同的数量的扶梯部分，可以满足不同长度扶梯的需求；通过设置可折叠的扶梯部分，来折叠和展开，可以有效的节约占地面积，便于去放和运输。
