TH93271B - Pipe tightening structure - Google Patents

Abstract

New request updated on 4/03/2016 to reliably restrain the pipe body with a simple structure regardless of the shrinkage and radial deformation of the pipe body while preventing the scraping of the outer surface of the pipe body. Even if the clip body 2 is moved along the outer surface A1 of the pipe body A to the point where the double-ended male coupling 1 is inserted, the distal face 41d of the softened portion 41 will not collide with the outer surface A1 of the pipe body A while it is kept subjected to radial expansion and deformation by the operating member 3. The clip body 2 is moved towards the locking flange 12 of the double-ended male coupling 1 and, after the softened portion 41 of the hook 4 is moved over the locking flange 12 in the axial direction, the clip body 2 is released from the radial expansion by the operating member 3. As a result, the clip body 2 is subjected to elastic contraction and radial deformation. And the distal end surface 41d of the softened portion 41 enters the constraint groove 13 of the double-sided male joint 1 through the application of radial contraction and deformation. At the same time, the softened portion 41 constrains the locking flange 12 in the axial direction to prevent it from moving. Subsequently, even though the pipe body A is subjected to radial contraction and deformation by the engagement of the clip body 2 with the outer surface A1 of the pipe body A and deterioration with age, the softened portion 41 moves inward in the radial direction by the locking flange 12, and the constrained condition of the softened portion 41 and the locking flange 12 is maintained.
