Abstract
The utility model discloses a hydraulic oil cylinder with an embedded sealing device. The hydraulic oil cylinder comprises a cylinder block, wherein a sleeve shaft portion is arranged in the cylinder block. The sleeve shaft portion comprises a main shaft, a sealing portion and a fixed portion. An open sealing steel ring gasket is arranged on the sealing portion. A first sealing rubber ring is arranged between the sealing portion and the fixed portion. A second sealing rubber ring is arranged between the fixed portion and the cylinder block. A separable third sealing rubber ring is arranged in a shaft hole of the sealing portion. The third sealing rubber ring is made of Teflon nylon and has perfect abrasion resistance. Through adoption of the third sealing rubber ring, the hydraulic oil cylinder with the embedded sealing device can maintain sealing performance of the whole main shaft even if the hydraulic oil cylinder operates for a long time.
