Abstract
The invention discloses a multi-sealing oil cylinder which comprises a cylinder block, an oil cylinder cap and a piston. The oil cylinder cap is fixed to the cylinder block through bolts. Sealing ring grooves are formed in the side face, making contact with the cylinder block, of the oil cylinder cap and the front face of the oil cylinder cap. O-shaped sealing rings are arranged in the sealing ring grooves, and when the O-shaped sealing ring on the side face loses efficacy, the O-shaped sealing ring on the front face can play the role of oil leakage prevention. Due to the fact that the front face of the oil cylinder cap is in close fit with the cylinder block to play the role of pressure reduction, the pressure is quite small when the oil pressure arrives at the O-shaped sealing ring in the front face, the oil cylinder cap can completely seal leaked hydraulic oil in the secondary sealing process, and thus the problem of oil leakage of the oil cylinder is solved.
