Document Type and Number:

WIPO Patent Application WO/2018/090377

Kind Code:

A1

Abstract:

Disclosed are a composite anchoring body (1), a pipeline connection device using the anchoring body (1), and a method for installing same. An elastic body (4) in the composite anchoring body (1) is a straight strip-shaped polyhedron with a wide bottom and a narrow top, wherein a bottom face (41), a left end face (42) and a right end face are all flat faces, the bottom face 41 is an isosceles trapezoid, and a top face (44) is a curved face formed by connecting flat faces in a curvedmanner. A number of racks (2) are embedded, at intervals, in the length L direction of the elastic body (4), and the tooth top direction of sawteeth (21) of the racks is parallel to the long side of each of the flat faces, which are connected to form the curved face. A horizontal face (443) of the elastic body is provided with a plurality of yielding portions (3) uniformly distributed in the length L direction thereof, and one rack (2) is adjacent to at least one of the yielding portions (3) in the width W direction of the elastic body (4). After at least one composite anchoring body (1) is connected end to end to form an annular anchoring body (20), and same is put into an anchoring chamber (11) of a bellmouth (10) of the pipeline connection device, the sawteeth (21) and an outer wall of a socket (13) are engaged. The composite anchoring body (1) and the pipeline connection device are easy to manufacture, convenient to use, have a good anchoring effect and are adapted to pipes of different diameters. The method for installing the pipeline connection device has simple operations and a high work efficiency.
