The invention relates to the field of hydraulic cylinders, in particular to a piston rod of a hydraulic cylinder. The piston rod of the hydraulic cylinder comprises a first lifting mechanism, a secondlifting mechanism, a third lifting mechanism and a stabilizing mechanism, the second lifting mechanism is arranged above the first lifting mechanism, and a traditional hydraulic cylinder extendable rod is improved into the second lifting mechanism and the third lifting mechanism. When the second lifting mechanism extends to the topmost end of a first sleeve in the first lifting mechanism, hydraulic oil is injected through a second oil injection pipe to drive the third lifting mechanism to extend in the second lifting mechanism, so that the piston rod of the hydraulic cylinder can stretch outand draw back for the second time, fine adjustment of the piston rod of the hydraulic cylinder is convenient, and the applicability of the hydraulic cylinder is better; and through the arrangement ofthe stabilizing mechanism, when the second lifting mechanism and the third lifting mechanism ascend and descend, a jacking rod can support a second sleeve and a piston rod body, and the hydraulic cylinder can be more stable in use.
本发明涉及液压缸领域,具体的说是一种液压缸活塞杆,包括第一升降机构、第二升降机构、第三升降机构和稳定机构组成,所述第一升降机构的上方设置有第二升降机构,将传统的液压缸伸缩杆改进为第二升降机构和第三升降机构,使得第二升降机构在第一升降机构的内部延伸至第一套筒的最顶端时,通过第二注油管注入液压油能够驱动第三升降机构在第二升降机构的内部进行延伸至,使得液压缸活塞杆能够进行二次伸缩,便于实现液压缸活塞杆的微调,使得液压缸的适用性更好,通过设置的稳定机构能够使得第二升降机构和第三升降机构在进行升降时,顶升杆能够对第二套筒和活塞杆体进行支撑扶持,能够使得液压缸在使用时更加的稳定。
