Oil pipe connecting structure and hydraulic oil cylinder

The utility model relates to the technical field of hydraulic oil cylinders, in particular to an oil pipe connecting structure and a hydraulic oil cylinder, the oil pipe connecting structure comprises a cylinder body, a fixing frame and a connecting pipe, and moving blocks are arranged at the two ends of the inner side of the fixing frame; the device has the beneficial effects that firstly, a pressing strip is pressed, a first push rod and a second push rod drive a special-shaped block to move in a special-shaped groove hole, then a movable block drives one end of a positioning rod to retract into a through hole, meanwhile, the special-shaped block extrudes a reset spring, and then limiting strips on the two sides of a connecting pipe are inserted into limiting grooves; when the connecting pipe is inserted into the bottom of the oil pipe, the position of the fixing groove is aligned with the position of the through hole, pressure applied to the pressing strip is removed, the positioning rod is inserted into t
