Abstract
The utility model relates to a cylinder barrel sealing mechanism, in particular to a cylinder barrel sealing mechanism for a three-level cylinder. The cylinder barrel sealing mechanism comprises an inner cylinder barrel and an outer cylinder barrel, the heads of the inner cylinder barrel and the outer cylinder barrel are sealed through a dustproof ring, an O-shaped ring and a seal ring, a guide ring is arranged between the inner cylinder barrel and the outer cylinder barrel, and the tails of the inner cylinder barrel and the outer cylinder barrel are in retained connection through a retainer ring. The cylinder barrel sealing mechanism for the three-level cylinder is simple in structure and convenient to use.
