发明名称 Pipe coupling
摘要 A pipe coupling for joining abutting sections of pipe particularly adapted for connecting corrugated plastic drain pipe to provide a strong yet flexible coupling having a relatively smooth external surface thereby avoiding entanglement of the coupling in the guide of a trencher for the subterranean laying of the pipe. The pipe coupling consists of a substantially flexible rectangular shaped sleeve having at least two rows of teeth disposed along the length of the sleeve and means for fastening the ends of the sleeve around two sections of pipe to allow each row of teeth to engage at least one corrugated groove disposed at or near the end of each section of pipe to provide a coupling having a wide range of applicability for connecting a variety of corrugated pipe configurations.
