Adjustable angle joining system and procedure for round tube profiles of different section (Patent ES 2685221 B2)

Removable and adjustable union system and procedure to join profiles of round tube of different diameters. The system consists of two groups of two flanges, a base flange and an adjustment flange, movable with respect to the base flange, which are coupled together by means of screws wedged in the shape of dovetail cone. This ensures the independent tightening of each profile and thus adjusting to the desired diameter. Both groups are joined by a screws and its respective nut, allowing the rotation between them and join at the desired angle. By means of this system, it is possible to join different round tube profiles without the need to carry out previous operations.
