However, no matter how the appearance of the type of pipe changes, most of the type of pipe needs to be connected by adopting a thermal shrinkage sleeve rubber ring socket joint in the process of main installation and construction, and the rubber ring socket joint is a connection mode adopted by the main stream of the market. However, the socket wall is basically in a thin-wall cylinder shape, the sealing ring is used for sealing water, the pipe does not have drawing resistance, the connection pulling resistance is low, the pipe is easy to be disjointed, and particularly after the settlement phenomenon occurs, the quality problem is more likely to occur later, so that potential safety hazards exist in use durability and the like. Meanwhile, the rubber ring adopted in the prior art is generally of an O-shaped ring or a single-tooth structure, the sealing performance is poor, in the installation process, the rubber ring is extruded during jacking, overturning can occur, and serious water leakage can occur once an installer does not find the rubber ring in time, so that the rubber ring is inconvenient to use.

Therefore, we propose a kind of anti-drop impeller reinforcing compound pipe connection structure.
