Abstract

The invention belongs to the technical field of oil cylinders and discloses a hydraulic oil cylinder comprising an oil cylinder body and a piston rod. A cylindrical cavity is arranged in the oil cylinder body. A rod core is arranged at the center of the cavity. The piston rod comprises a piston portion and a rod portion, wherein the cross section of the piston portion is in a circular ring shape.The piston portion is connected into the cavity in a sliding manner. One end of the rod portion is fixed to the piston portion. The rod portion penetrates through the oil cylinder and extends out of the oil cylinder. The other end of the rod portion is connected with an end block. The end block, the inner portion of the rod portion and the outer portion of the oil cylinder body define a first oilcavity. The rod portion, the piston portion, the rod core and the inner portion of the oil cylinder body define a second oil cavity. The rod core and the oil cylinder body are provided with a first oil channel and a second oil channel, wherein the first oil channel communicates with the first oil cavity, and the second oil channel communicates with the second oil cavity. The oil cylinder body is provided with a third oil channel communicating with the first oil cavity and the second oil cavity. The third oil channel is provided with an oil pumping unit. Compared with the prior art. The hydraulic oil cylinder can utilize the originally possessed moving state of the piston rod to accelerate extension and resetting of the piston rod, and therefore the hydraulic oil cylinder can be rapidly used.

Description

technical field [0001] The invention belongs to the technical field of oil cylinders, and specifically discloses a hydraulic oil cylinder. Background technique [0002] A hydraulic cylinder is a device that converts hydraulic energy into mechanical energy, mainly to achieve linear reciprocating motion or reciprocating swing. Due to the advantages of large power and stable movement of hydraulic equipment, with the development and progress of hydraulic technology, hydraulic cylinders are widely used in machinery, construction and other fields. The hydraulic cylinder is generally composed of a piston rod and an oil cylinder. The piston rod generates power under the action of liquid pressure, and is restored by liquid suction or external force, so that the piston rod moves in the oil cylinder. [0003] When the piston rod is extending or recovering, the liquid in the cylinder needs to be injected and discharged. When the oil hole is small or the oil circuit is long, the piston ...
