Hand-cranking folding ladder
The invention discloses a hand-cranking folding ladder. The hand-cranking folding ladder comprises main ladder rods which are arranged in a bilateral symmetry mode, wherein auxiliary ladder rods are arranged on the front sides of the main ladder rods; folding devices capable of enabling the ladder to stretch out and draw back are arranged between the main ladder rods on the two sides and between the auxiliary ladder rods on the two sides at equal intervals; first sliding blocks are fixedly arranged on the lower side walls of the auxiliary ladder rods; second sliding blocks are fixedly arrangedon the left side walls of the auxiliary ladder rods; and first guide grooves which are in sliding fit with the second sliding blocks are formed in the right side walls of the main ladder rods. According to the hand-cranking folding ladder, the ladder can be folded or unfolded by manually extruding or stretching the ladder, moreover, a mechanical structure is driven by shaking a handle to realizethat two sections of the ladder are combined into one section, so that the height of the ladder is increased, the height of the ladder is increased through a hand-cranking mode, meanwhile, the effectof saving labor is achieved, moreover, the operation is simple and convenient, the manufacturing cost is low, and the occupied area can be reduced and the space can be saved when the ladder does not need to be used.
本发明公开了一种手摇折叠梯，包括左右对称设置的主梯杆，所述主梯杆前侧设有辅助梯杆，两侧所述主梯杆之间以及两侧所述辅助梯杆之间均等间距设有可使梯子伸缩的折叠装置，所述辅助梯杆下侧壁固设有滑块一，所述辅助梯杆左侧壁固设有滑块二，所述主梯杆右侧壁开设有与所述滑块二滑动配合的导向槽一；本发明可以通过人工挤压或拉伸梯子使梯子折叠或张开，并且通过摇动手柄带动机械结构实现两节梯子合并成一节，使梯子高度增加，通过手摇的方式来不仅增加梯子高度，同时到达省力的效果，并且操作简便，制造成本低，可在不需要使用时减小占地面积节省空间。
