[0002] Hydraulic cylinders are one of the common hydraulic equipment in our life. At the same time, there are hydraulic cylinders of different models and sizes according to different usage scenarios. In order to improve the carrying capacity of hydraulic cylinders, the diameter of hydraulic cylinders is also increasing. However, the current technical considerations are not enough Perfect, has the following disadvantages: when the traditional hydraulic cylinder is working, it pushes the expansion and contraction of the piston rod through the input and output of the oil holes at the left and right ends of the cylinder. When the oil flows in from the oil hole, the distribution is uneven, which in turn causes the piston block to receive a large hydraulic pressure near the oil inlet hole, causing uneven pressure on the sliding surface of the piston block. After a long time of use, it will cause the piston block to move to one side Tilting and wear occur, which in turn affects the sealing of the hydraulic cylinder, resulting in abnormal operation of the hydraulic cylinder and shortening the service life of the hydraulic cylinder

The invention discloses a large-diameter hydraulic oil cylinder with uniformly distributed stress. The large-diameter hydraulic oil cylinder structurally comprises a positioning rod, a hydraulic oil cylinder main body, a first connecting buckle, a hydraulic piston rod and a second connecting buckle, wherein the hydraulic oil cylinder main body is of a cylindrical structure; the positioning rod abuts against the hydraulic oil cylinder main body; and the first connecting buckle is welded to the hydraulic oil cylinder main body. According to the large-diameter hydraulic oil cylinder, a hydraulicoil distributor and a hydraulic driving structure are matched with each other, so that when hydraulic oil is input, the thrust on a piston block is more uniform, the situation that the sliding surfaceof the piston block is not uniformly pressed, then the piston block inclines towards one side and the abrasion is accelerated is effectively avoided, the sealing performance of the hydraulic oil cylinder is guaranteed, and the service life of the hydraulic oil cylinder is prolonged.
