Portable multifunctional folding ladder
The invention belongs to the field of ladders, and discloses a portable multifunctional folding ladder. The portable multifunctional folding ladder is characterized in that a first ladder beam is arranged to be a plurality of first ladder beam units and a plurality of second ladder beam units which are alternately arranged and are connected by virtue of revolute pairs, the lower end of the first ladder beam is connected with a third ladder beam unit by virtue of a revolute pair, the upper end of a second ladder beam is connected with a fourth ladder beam unit through a revolute pair, the rotating directions of the corresponding revolute pairs on the first ladder beam are sequentially opposite, the rotating directions of the corresponding revolute pairs on the second ladder beam are sequentially opposite, the revolute pairs can rotate by 180 degrees, and the first ladder beam units and the second ladder beam can be folded. A plurality of treading units are arranged between the first ladder beam and the second ladder beam at equal intervals, the first ladder beam and the second ladder beam can be folded at the same time, and the occupied space can be further reduced.
本发明属于梯子领域，公开了一种便携式多功能折叠梯子，本发明中，通过将第一梯梁设置成多个交替设置并借助转动副连接的第一梯梁单元和第二梯梁单元，第一梯梁下端借助转动副连接有第三梯梁单元，第二梯梁上端借助转动副连接有第四梯梁单元，所述第一梯梁上对应的转动副能够转动的方向依次相反，所述第二梯梁上对应转动副能够转动的方向依次相反，且转动副能够转动180°，能够实现第一梯梁单元和第二梯梁的可折叠，踩踏单元包括多个，且多个踩踏单元等间距设置在第一梯梁与第二梯梁之间，第一梯梁和第二梯梁能够同时折叠可以进一步减小所占空间。
