A CONNECTION STRUCTURE FOR PLASTICS PIPE

摘要

A connection structure for a plastic pipe to dually maintain the watertightness with a rubber ring is provided to prevent the water leakage by pushing the rubber ring with a pusher. A connection structure for a plastic pipe comprises a connector(20), a pusher(13), and connection covers(30,31). The connector is connected to a synthetic resin conduit(10). The connector comprises an assemblage groove and a pusher groove(22). The assemblage groove has an assembly incline(24). The pusher groove is formed at the outer side of the assemblage groove. The pusher is installed in the outer side of three angles rubber ring(11). The pusher is combined at the incline formed at a protrusion groove(33) of the connection covers. Three angles rubber ring is combined in the assemblage groove. The connection cover has the incline connecting with the pusher, at the one side of the assemblage groove.
