The invention relates to the field of supporting leg structures, in particular to a leveling supporting leg. A nut body is installed in a supporting leg shell through a bearing, the nut body comprises an upper trapezoidal thread, a lower trapezoidal thread and a limiting protrusion, an ascending lead screw is installed in the upper trapezoidal thread, a descending lead screw is installed in the lower trapezoidal thread, the upper trapezoidal thread and the lower trapezoidal thread are arranged in different thread directions, and the upper bearing is clamped between the supporting leg shell and the nut body. The lower bearing is clamped between the supporting leg shell and the limiting protrusion, the diameter of the outer layer of the ascending lead screw is smaller than that of the inner layer of the descending lead screw, and the ascending lead screw is inserted into the descending lead screw after being recycled. The length size of the leveling supporting leg body is effectively reduced under the condition that the stroke is not reduced, the leveling supporting leg is small and compact, and the requirement for vehicle transportation off-road performance is met.
本发明涉及撑腿结构领域,特涉及一种调平撑腿。本发明的螺母体通过轴承安装在撑腿外壳内,螺母体包括上梯形螺纹、下梯形螺纹、限位凸起,上梯形螺纹内安装上行丝杆,下梯形螺纹内下行丝杆,上梯形螺纹和下梯形螺纹设置不同的螺纹方向,上部的轴承卡设在撑腿外壳与螺母体之间,下部的轴承卡设在撑腿外壳与限位凸起之间,上行丝杆外层直径比下行丝杆内层直径小,回收后,上行丝杆插入下行丝杆内。本发明在不降低行程的情况下有效减小调平撑腿本体长度尺寸,做到小而紧凑,满足车辆运输越野性能需要。
