The invention relates to the technical field of agricultural machinery, in particular to a trailer supporting leg mechanism. The trailer supporting leg mechanism comprises a square outer sleeve, an adjusting screw and a square inner supporting leg arranged in the outer sleeve in a sliding mode, wherein one end of the inner supporting leg is fixedly connected with a nut top plate, and the other end of the inner supporting leg is a supporting foot; the adjusting screw penetrates through the outer sleeve and the inner supporting leg and is in threaded fit with the nut top plate to adjust the up-down telescopic amount of the inner supporting leg. According to the trailer supporting leg mechanism, the problem that a trailer supporting leg can be installed and disassembled only by means of a jack and other external auxiliary tools in the actual use process in the prior art can be solved.

    本发明涉及农用机械技术领域,尤其是一种拖车支腿机构,包括方形外套管、调节螺杆和滑动设置在外套管内部的方形内支腿,所述内支腿的一端固定连接有螺母顶板,所述内支腿的另一端为支承脚,所述调节螺杆穿在外套管和内支腿中并与螺母顶板螺纹配合调节内支腿的上下伸缩量,本发明可以解决现有技术中拖车支腿在实际使用时需要借助千斤顶等外部辅助工具才能实现安装与拆卸的问题。
