The ultrahigh pressure oil cylinder structure comprises an oil cylinder body, a transition plate, a piston, a rear plug and a front guide sleeve, the transition plate coaxially sleeves the inner side of the cylinder bottom of the oil cylinder body, the piston sleeves the inner side of the cylinder wall of the oil cylinder body in a sliding mode, and the rear plug is installed at the cylinder bottom of the oil cylinder body and the center of the transition plate in a penetrating mode. The front guide sleeve is installed on a cylinder opening of the oil cylinder body, a high-pressure oil cavity is formed between the piston and the transition plate, and a low-pressure oil cavity is formed between the piston and the front guide sleeve. The ultrahigh-pressure oil cylinder structure isolates damage of high-pressure oil to a stress concentration area, changes the pressure direction of the stress concentration area and improves the position of a bottom surface pressure acting point, so that the maximum stress of an o
