Abstract
The utility model discloses a fastening connecting assembly for pipes. The fastening connecting assembly comprises a joint and a jackscrew. The joint comprises a connecting plate. One end of the connecting plate is bent with a pulling plate and the other end of the connecting plate is bent with a jacking plate tilting towards the interior of the joint. Two sides of the jacking plate are bent with flanging. One end of the jackscrew is threadingly connected to the pulling plate and the other end of the jackscrew abuts against the jacking plate. When the jackscrew is rotated tightly, the pulling plate expands downwardly and the jacking plate expands upwardly and drives the flanging to expand upwardly so that four-surface expansion connection is achieved by the joint and inner walls of the pipes. The fastening connecting assembly is advantaged by being simple in structure, convenient in installation and is capable of effectively improving the fastening strength.
