The invention relates to the technical field of semitrailer supporting, in particular to a supporting leg of a semitrailer. A rack is arranged on the supporting leg, driving gears are arranged on two sides of the rack, and power generated by manually rotating a rocking handle by a person is transmitted to the driving gears through a transmission device in a shell; the motion of the driving gears drive the rack and the the semi-trailer supporting assembly is simple in overall structure, low in machining and manufacturing cost, easy to use and suitable for being used as a supporting assembly when a semi-trailer is idle, and the supporting requirement of the semi-trailer can be well met; under the condition that the requirement of the rocking handle for driving the transmission device is met, a limiting effect on the supporting legs is formed by folding the rocking handle, the rocking handle holding part and the shell, on one hand, the attractiveness of the whole device is improved, on the other hand, an additional limiting structure can be omitted, and the manufacturing and machining cost of the device is further reduced.
本发明涉及半挂车支撑技术领域,具体涉及一种半挂车的支撑腿,本发明通过在支腿上设置齿条,且在齿条的两侧设置驱动齿轮,通过在壳体内的传动装置将人员的手动转动摇柄产生的动力传递给驱动齿轮,驱动齿轮的运动带动齿条和支腿实现升降功能,本发明整体结构简单,加工制造成本较低易于使用,适合作为半挂车闲置时的支撑组件,可以很好地提供半挂车的支撑需求,与此同时,通过将摇柄铰接在转轴上,在满足摇柄对传动装置驱动的要求的情况下,通过折叠摇柄,摇柄握持部与壳体形成对支腿的限位作用,这一方面提升了整个发明的美观度,另一方面也可省去额外的限位结构,进一步降低了本发明的制造加工成本。
