The invention discloses a parking frame crank structure with a crank not hindering folding of supporting legs. The parking frame crank structure comprises a middle shaft and a middle shaft sleeve which are rotationally arranged on a frame, cranks are arranged at two ends of the middle shaft, and pedals arranged at the cranks respectively and rotationally; at least one crank is provided with a supporting leg in a sliding mode, one end of each supporting leg extends out of the end, located on the corresponding pedal, of the corresponding crank, a positioning structure for fixing the supporting leg after the supporting leg slides is arranged in each crank, and the parking frame crank structure further comprises an anti-rotation structure for preventing the crank from rotating when one end ofthe supporting leg makes contact with the ground. The parking frame crank structure has the advantages that the support legs are arranged in the cranks and can extend and retract freely, so that the cranks are prevented from blocking the support legs, the support legs are invisible, and the attractiveness is improved.

    本发明公开了一种曲柄不会阻碍撑脚收起的停车架曲柄结构,包括转动设置在车架上的中轴和中轴套,设置在中轴两端的曲柄,分别转动设置在曲柄上的脚踏,所述至少一个曲柄上滑动设置有撑脚,撑脚的一端从曲柄位于脚踏的那端伸出,曲柄内设置有在撑脚滑动后定住撑脚的定位结构,还包括撑脚的一端在与地面接触时防止曲柄转动的防转结构。本发明的优点是:将撑脚设置在曲柄内,然后可以自由伸出和缩进,这样即避免了曲柄挡住撑脚,还使得撑脚隐形,增加美观。
