The invention discloses a pull rod type folding mechanism for an aviation hydraulic jack, and relates to the technical field of aviation jacks, the pull rod type folding mechanism for the aviation hydraulic jack comprises a jack main body, and a base frame is fixedly mounted outside the lower end of the jack main body; second pull rods are arranged outside the base frame in a 120-degree included angle mode, and each second pull rod is connected with a first pull rod; the end, matched with the first pull rod, of the second pull rod is chamfered on one side, so that the second pull rod and the first pull rod can only rotate by one angle, the second pull rod rotates along the pull rod fixing pin, the second pull rod can be rotated anticlockwise to be horizontal with the first pull rod, and the second pull rod can be rotated anticlockwise to be horizontal with the first pull rod. At the moment, the plane of the second pull rod is attached to the plane of the upper groove of the first pull rod, the limiting effect is achieved, and the pull rods stop rotating; when the jack is folded, the quick release pin is pulled out firstly, the two short edges of the pull rod rotate upwards and then are fixed to the folding connector through the quick release pin, and folding of the jack is completed.
本发明公开了一种用于航空液压千斤顶的拉杆式收拢机构,涉及航空千斤顶技术领域,该用于航空液压千斤顶的拉杆式收拢机构包括千斤顶主体,该千斤顶主体下端的外部固定安装有底座架;底座架的外部呈120度夹角式设置拉杆二,且每个拉杆二连接有拉杆一;所述的拉杆一与螺筒固定座连接本发明中,拉杆二与拉杆一配合的一端采用一侧倒角的方式,使拉杆二与拉杆一只能往一个角度转动,拉杆二沿着拉杆固定销转动,可将拉杆二逆时针旋转至与拉杆一水平,此时拉杆二的平面与拉杆一上槽的平面贴合,起到了限位作用,拉杆停止转动;本发明中,千斤顶收拢时,先拔出快卸销,使拉杆二短边向上转动后与收拢接头通过快卸销进行固定,完成千斤顶的收拢。
