The invention relates to the technical field of hydraulic oil cylinders, in particular to a supporting-height-adjustable hydraulic oil cylinder. The supporting-height-adjustable hydraulic oil cylinder comprises an oil cylinder body and an extendable rod, wherein the extendable rod is located at the upper end of the oil cylinder body and is movably connected with the oil cylinder body, the lower end of the outer surface of the extendable rod is sleeved with a cleaning mechanism, the position, close to the upper end, of the outer surface of the oil cylinder body is sleeved with and fixedly connected with a first fixing disc, the upper end of the extendable rod is fixedly connected with a second fixing disc, an adjusting mechanism is arranged on the outer surface of the upper end of the second fixing disc, protection mechanisms are arranged between the first fixing disc and the second fixing disc, and the three groups of protection mechanisms are annularly arranged on the outer side of the extendable rod at equal intervals. According to the device structure, when the extendable rod is jacked and contracted, a certain protection effect can be achieved on the extendable rod, the direct touch probability of external objects is reduced, the touch force effect is reduced, and the collision force is buffered, so that the service life of the hydraulic oil cylinder is effectively prolonged, and the damage probability of the hydraulic oil cylinder is reduced.

    本发明涉及液压油缸技术领域,尤其是涉及一种支撑高度可调式的液压油缸,包括油缸主体与伸缩杆,所述伸缩杆位于油缸主体上端并与油缸主体活动连接,所述伸缩杆外表面下端套接有清理机构,所述油缸主体的外表面靠近上端的位置套接并固定连接有固定盘一,且伸缩杆的上端固定连接有固定盘二,所述固定盘二的上端外表面设置有调节机构,所述固定盘一与固定盘二之间设置有防护机构,且防护机构的数量为三组并环形等距离设在在伸缩杆外侧。该装置结构在伸缩杆顶升以及收缩时,能够对伸缩杆起到一定防护效果,减少外界物体直接碰触几率,降低碰触力度的效果,对碰撞力度缓冲,从而有效的延长装置使用寿命,降低设备损坏几率。
