The invention relates to a linear elastic extension rod mechanism with spiral extension and linear support, which belongs to the field of machinery and comprises an elastic winding drum assembly, three linear extension support assemblies and a load mounting top plate assembly. The elastic winding drum assembly is axially and vertically arranged; the load mounting top plate assembly is horizontally arranged at the top of the elastic winding drum assembly; the axial top end of the elastic drum assembly is butted with the center of the lower surface of the load mounting top plate assembly; the three linear extension supporting assemblies are evenly distributed on the outer wall of the bottom end of the elastic winding drum assembly in the circumferential direction, and the tops of the three linear extension supporting assemblies are fixedly connected with the lower surface of the load mounting top plate assembly. The elastic winding drum assembly stretches out and draws back in the axial direction, the load installation top plate assembly is jacked up, and the three linear stretching supporting assemblies are driven to stretch out or retract back. The problems that a traditional unfolding mechanism is small in storage ratio and large in folding size are solved, the problem of rotation of a large-storage-ratio spiral stretching rod mechanism is solved, orientation is guaranteed, and rigidity is improved.

    本发明涉及一种螺旋伸展和直线支撑的线弹性伸杆机构,属于机械领域,包括弹性卷筒组件、3个线性伸展支撑组件和载荷安装顶板组件;弹性卷筒组件轴向竖直放置;载荷安装顶板组件水平设置在弹性卷筒组件的顶部;弹性卷筒组件的轴向顶端与载荷安装顶板组件下表面中心对接;3个线性伸展支撑组件沿周向均匀分布在弹性卷筒组件的底端外壁处,且3个线性伸展支撑组件的顶部均与载荷安装顶板组件下表面固连;弹性卷筒组件实现沿轴向伸缩,将载荷安装顶板组件顶起,并带动3个线性伸展支撑组件拉伸或缩回。本发明解决了传统展开机构收纳比小、收拢体积大的问题,还解决了大收纳比螺旋伸杆机构旋转的问题,保证定指向和提高刚度。
