Foldable stair board
The invention relates to the technical field of climbing machinery, in particular to a foldable stair board. Under the cooperation of key grooves formed by the outer spline shaft, the inner spline shaft and the spline holes, the folding angle between the two pedals can be locked, and then the stair board with the corresponding shape can be formed according to the set requirement. Meanwhile, based on the effect of the outer spline shaft, all the pedals can be folded together after the outer spline shaft is pulled out, the size of the stair board is reduced, carrying, loading and unloading are facilitated, and use convenience is improved. The pedal is transported to a site, then the pedals are unfolded one by one according to needs and then locked, and the pedals are increased layer by layer until the requirements are met. And more pedals can be detached, and less pedals can be added, so that the operation is convenient. Due to the fact that the portable stair climbing device is small in size and convenient to carry, the portable stair climbing device can be rapidly conveyed to a site at some positions where temporary climbing is needed and unfolded to form stairs meeting requirements.
本发明涉及攀爬机械技术领域，具体是一种可折叠楼梯板。本发明在外花键轴、内花键轴和花键孔彼此形成的键槽配合下，能够锁定两个踏板之间的折叠角度，进而可以按照设定的要求形成对应形状的楼梯板。同时，基于外花键轴的作用，能够在拔出外花键轴之后，将各个踏板彼此折叠在一起，减小楼梯板的体积，以便于搬运和装卸，提高了使用的便捷性。先将本发明运送到现场，然后根据需要将踏板逐个展开然后锁定，一层一层增加，直到满足要求。多的踏板可以拆除，少的可以增加，操作方便。由于本发明体积较小，且携带方便，因此在一些临时需要攀爬的位置，可以快速运送至现场，并展开形成满足要求的楼梯。
