Rubber tube connecting device

A rubber pipe connecting device comprises a rubber pipe, the inner diameter of the rubber pipe is larger than the outer diameter of a connected seamless steel pipe, the rubber pipe partially coincides with the inner end of the seamless steel pipe to form interference fit, the inner diameter of the seamless steel pipe is larger than the outer diameter of a liner pipe, and the seamless steel pipe partially coincides with the outer end of the liner pipe to form interference fit; a clamping sleeve is arranged on the outer side wall of the overlapped part of the rubber pipe and the seamless steel pipe. The utility model provides a rubber tube connecting device, which solves the problems of unstable welding quality, low reliability and high cost in the prior art, adopts an interference fit mode at the overlapping part, is internally provided with a convex ring and is externally and tightly attached to a clamping sleeve, so as to determine the sealing property and the connecting reliability. 一种橡胶管连接装置，包括橡胶管，橡胶管的内径大于
