TH158894B - Pipe tightening structure - Google Patents

Abstract

The new request, revised 4/03/2016 to reliably brace the tubular body with a simple structure regardless of shrinkage and Radial deformation of the pipe body in the presence of anti-scuffing on the outer surface of the tube body. Although the clip 2 tank is moved along the A1 outer surface of the A tube body to the point where the coupling Double-sided male type 1 was inserted, 41d far end surface of the softened part 41, would not collide with the outer surface A1 of the A tube body, while being treated to be distorted and radially deformed by Working section 3, clip body 2 is moved onto the locking flange 12 of the double-sided male coupling 1, and after the softening part 41 of the hook 4 moves over the locking flange 12 in axial direction. The clip 2 body is released from radial expansion by the working segment 3, as a result, the clip 2 body is retracted and deformed, flexible and radially. And the distal surface 41d of the softened portion 41 is entered into the force groove 13 of the double-sided male joint 1 through the use of contraction and radial deformation. At the same time The softened section 41 is driven against the locking flange 12 in the axial direction to prevent it from moving. Thereafter, though, the A tubing is shrunk and radially deformed following the clipping of the clip 2 body onto the outer surface A1 of the A tubing body and degradation with life. But the softened part 41 will move inward in the radial direction. According to the locking flange 12 and the forced condition of the softened section 41 and the locking flange 12 are maintained.

New request updated 4/03/2016 1. Structure of pipe tightening consists of A duplex male coupling that is inserted into the pipe body which can be flexibly deformed; The clip body can be flexibly deformed in the radial direction through which the hoses are retained. Between the clip body and the aforementioned double-sided couplings and are tightened; & nb:
