Abstract
A sealing cover for covering an opening of a barrel body includes an outer cover body, an inner cover body, an airtight ring and an operating member. The outer cover body includes two pivot connecting portions. The airtight ring is sleeved on an outer peripheral surface of the inner cover body. The operating member is pivotally connected to the pivot connecting portions and the inner cover body. The operating member is operable to pivot so as to drive movement of the inner cover body between a sealed position and an unsealed position. When at the sealed position, the airtight ring is deformed and airtightly pressed between the barrel body and the outer cover body. When at the unsealed position, the airtight ring restores to its original shape and is configured not to be pressed between the barrel body and the outer cover body.
