Abstract

The invention discloses a double-locked oil cylinder. The double-locked oil cylinder comprises a cylinder tube, a piston, a locking nut, a cylinder top cover and a saddle; the cylinder tube is arranged vertically, the cylinder top cover is mounted at the upper end of the cylinder tube, and a sealing clamping ring is arranged on the inner wall of the lower end of the cylinder tube; the sealing clamping ring is provided with a plurality of first sealing grooves and first guiding grooves, first sealing rings are embedded in the first sealing grooves, the piston extends into the cylinder tube, andthe top of the piston is a sealing head matched with the inner wall of the cylinder tube; the outer wall of the sealing head is provide with a plurality of second sealing grooves and second guiding grooves, and second sealing rings are embedded in the second sealing grooves; and a jacking oil hole and a return stoke oil hole are formed in the piston, and upper open ends of the jacking oil hole and the return stoke oil hole are located on the upper end face of the sealing head. According to the double-locked oil cylinder, the locking nut is screwed on the outer wall of the cylinder tube, afterobjects are supported by the oil cylinder, hydraulic pressure and the locking nut can be used together for maintaining, the double locking function is achieved, and reliability and safety are higher.

Description

【Technical field】 [0001] The invention relates to the technical field of hydraulic pressure, in particular to the technical field of oil cylinders. 【Background technique】 [0002] The oil cylinder is a hydraulic cylinder, and the hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of ​​the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow and pressure of the fluid, and the output is the linear motion speed and force. The piston of the hydraulic cylinder can complete linear reciprocating motion, and the output linear displacement is limited. A hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy for reciprocating linear motion. The hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer dev...
