The invention discloses a double-acting full-stroke self-locking jack, and relates to the technical field of self-locking jacks, the double-acting full-stroke self-locking jack comprises a jack body, one side of the jack body is provided with an oil inlet hole, one side of the oil inlet hole is slidably provided with a jacking piece, one side of the oil inlet hole is provided with a scale cavity, and the oil inlet hole is communicated with the interior of the scale cavity; an oil inlet hole is formed in the jack body and communicates with the interior of the jack body, a piston is slidably mounted in the jack body, and a piston rod is connected to one side of the piston, so that one side of the movable tooth block abuts against one side of the rotating tooth, the piston is limited, and movement of the piston is rapidly stopped; according to the follow-up auxiliary self-locking mechanism, the piston rod is effectively prevented from being subjected to auxiliary self-locking when the piston rod is not tightly gathered in the gathering process of the locking piece, the stability of the jack in the using process is improved, the control mode of the follow-up auxiliary self-locking mechanism is simple and easy to control, the follow-up auxiliary self-locking mechanism is high in effectiveness and safety, double-acting hydraulic reset is achieved, and the installation space can be saved.

    本发明公开了一种双作用全行程自锁千斤顶,涉及到自锁千斤顶技术领域,包括千斤顶本体,千斤顶本体的一侧设有进油孔,进油孔的一侧滑动安装有顶升件,进油孔的一侧设有刻度腔体,进油孔和刻度腔体的内部相连通,进油孔和千斤顶本体的内部相连通,千斤顶本体的内部滑动安装有活塞,活塞的一侧连接安装有活塞杆使活动齿块的一侧抵接于转动齿的一侧,并对活塞进行限位,使活塞进行快速的止住移动,有效地防止在上述锁紧件在聚拢过程中若对活塞杆的聚拢不紧密时,对活塞杆进行辅助自锁,提升千斤顶在使用过程中的稳定性,上述随动辅助自锁紧机构的控制方式简单易控、有效性强,安全性高,双作用液压复位且可节省安装空间。
