The invention discloses a high-pressure-resistant oil cylinder in a composite structure for jacks. The high-pressure-resistant oil cylinder consists of a three-layer thick-wall cylinder, pressure sensors and a pressure display, wherein the three-layer thick-wall cylinder comprises an inner cylinder, a middle cylinder and an outer cylinder; the outer diameter of the inner cylinder is the same as the inner diameter of the middle cylinder; the outer diameter of the middle cylinder is the same as the inner diameter of the outer cylinder; one pressure sensor is mounted on the inner cylinder wall of each layer; the pressure display is positioned on the outer wall of the outer cylinder; the inner cylinder is made of cast steel; the middle cylinder is made of alloy steel; the outer cylinder is made of glass fiber reinforced plastics. The high-pressure-resistant oil cylinder disclosed by the invention has the benefits that three cylinders are arranged in a sleeving manner and in clearance fit, so that the strength of the oil cylinder is improved; the oil cylinder in the structure is small in size and light in weight, so that the oil cylinder has high superiority; the oil cylinder is provided with the pressure sensors and the pressure display, so that the real-time pressure in each layer of the cylinder can be known, and the safe operation is facilitated.
