Abstract
The utility model relates to an oil cylinder, in particular to a three-level oil cylinder. The three-level oil cylinder comprises an outer cylinder barrel, a middle cylinder barrel and an inner cylinder barrel, wherein a piston rod is connected in the inner cylinder barrel in an inserted way, and the space between the inner cylinder barrel and the piston rod, the space between the middle cylinder barrel and the inner cylinder barrel and the space between the outer cylinder barrel and the middle cylinder barrel are respectively sealed by sealing mechanisms. Each sealing mechanism comprises a dustproof ring, an O-shaped ring, a sealing ring and a guide ring which are sequentially distributed, and a bottom cover is arranged on the tail portion of the outer cylinder barrel. The three-level oil cylinder is simple in structure and convenient to use.
