The invention relates to the technical field of jacks, in particular to an umbrella type folding aircraft jack which comprises a hydraulic driving assembly and at least three sets of supporting assemblies, the hydraulic driving assembly is composed of a driving body and a driver, and the driver is installed at the lower end of the driving body and used for controlling the driving body. Wherein the lifting assembly is installed on the driving body, the supporting assembly comprises an upper support, an inclined supporting column and a sliding support, the upper support is fixedly installed at the upper end of the driving body, the sliding support is connected with the lifting assembly, a pull rod is hinged to the other end of the sliding support, and the other end of the pull rod is hinged to the inclined supporting column. Through mutual cooperation of the supporting assembly and the lifting assembly, when the device needs to be folded and unfolded, the lead screw is rotated to drive the movable nut and the sliding support to move up and down, so that the pull rod moves up and down, and rapid folding and unfolding of the jack are achieved.

    本发明涉及千斤顶技术领域,尤其涉及一种伞式收拢的飞机千斤顶,其包括液压驱动组件和至少三组支撑组件,所述液压驱动组件由驱动主体和驱动器组成,所述驱动器安装在驱动主体的下端部,用于控制驱动主体,其中:所述驱动主体的上安装有升降组件,所述支撑组件包括上支座、斜支柱和滑动支座,所述上支座固定安装在驱动主体的上端,所述滑动支座与升降组件连接,且另一端铰接有拉杆,所述拉杆的另一端与斜支柱铰接。本发明通过设置支撑组件和升降组件的相互配合,当需要对该装置进行收拢和展开时,通过转动丝杆,带动移动螺母和滑动支架上下移动,从而使得拉杆上下移动,达到千斤顶的快速收拢和展开。
