Title:
CONNECTION STRUCTURE OF CORRUGATED PIPE
Document Type and Number:
WIPO Patent Application WO/2011/126251
Kind Code:
A2
Abstract:
According to the present invention, a connection structure of a corrugated pipe comprises a corrugated pipe, a clamping nut located outside the corrugated pipe, a confinement ring mounted on a valley of the corrugated pipe and held in position of the clamping nut, a connection body having an insertion portion inserted into the clamping nut and having male threads threaded to the clamping nut, and a packing member located between an end of the corrugated pipe and the insertion portion to compress and deform the end of the corrugated pipe when the clamping nut is clamped and to provide sealing between the end of the corrugated pipe and the insertion portion. Since the packing member provides sealing between the insertion portion of the connection body and the end of the corrugated pipe, a gap may minimally occur and reliability is increased.
