The invention relates to the field of underwater equipment, in particular to a launching cylinder of underwater equipment, which comprises an inner cylinder, an outer cylinder and a sealing structure between the inner cylinder and the outer cylinder, an inner cylinder convex ring and an outer cylinder convex ring are respectively arranged at the end parts of the same ends of the inner cylinder and the outer cylinder, and the sealing structure comprises an inter-cylinder sealing ring; the inner edge and the outer edge of the inter-cylinder sealing ring are connected to the inner cylinder protruding ring and the outer cylinder protruding ring in a sealed mode respectively, bearing rings are arranged on the sides, close to the inter-cylinder sealing ring, of the inner cylinder protruding ring and the outer cylinder protruding ring and provided with supporting faces facing the inter-cylinder sealing ring, and the inner edge and the outer edge of each bearing ring are in lap joint with the surface of the inner cylinder protruding ring and the surface of the outer cylinder protruding ring respectively. The inner cylinder and/or the outer cylinder are/is provided with a bearing frame, and the bearing frame is connected with a tensioning piece which penetrates through the gap between the inner cylinder protruding ring and the outer cylinder protruding ring and tensions the bearing ring. The problem that in the prior art, a sealing ring between two layers of cylinders is prone to damage, and consequently sealing fails is solved.

    本发明涉及水下装备领域,具体涉及一种水下装备的发射筒,包括内筒、外筒以及两者之间的密封结构,内筒和外筒的同一端的端部分别设有内筒凸环和外筒凸环,密封结构包括筒间密封环,筒间密封环的内外边缘分别密封连接在内筒凸环和外筒凸环上,内筒凸环和外筒凸环的靠近筒间密封环的一侧布置有承载环,承载环具有朝向筒间密封环的支撑面,承载环的内外边缘分别搭接在内筒凸环和外筒凸环的表面,内筒和/或外筒上设有承载架,承载架上连接有穿过内筒凸环和外筒凸环的间隙并拉紧承载环的拉紧件。本发明解决了现有技术中的双层筒间的密封环容易损坏而导致密封失效的问题。
