摘要

Extendable spool for connections in fluids pipes, of the type of which are formed by two halves susceptible of mutually sliding coupling, for which one of the halves presents a cylindrical portion (1) that emerges orthogonally from a base (2) circular circular, and whose internal face has, in the vicinity of its embouchure, an annular groove (3) intended to receive and house a seal between both halves, while the opposite half has a corresponding cylindrical portion (6), of external diameter slightly lower than the internal diameter of the cylindrical portion (1) of the first half, for its sliding housing in the latter, Characterized in that the first part or half above further comprises a rod (4), externally threaded, orthogonally projected wing base (2) on the same side as the cylindrical portion (1), parallel to and spaced from this last, this rod element being dimensioned so that it extends to approximately the same length as said cylindrical portion (1); Because the second part or half mentioned also includes a section of tubular element (8), internally hollow, which emerges orthogonally to the base (7) on the same side as the cylindrical portion (6), parallel to, and separated from the latter, in a position susceptible to facing the section of rod element (4) of the first half when both halves are coupled together, by housing the cylindrical portion (6) of smaller diameter inside the cylindrical portion (1) ) of larger size during the operative condition of the reel, and said section of tubular element (8) being dimensioned so that it has a length that extends to approximately the height of the cylindrical portion (6), and an internal diameter that allows the introduction and housing of the rod portion (4) of the other half; And in that the rod section (4), externally threaded, allows the coupling of a nut and washer assembly, constituting a stop for, and a thrust assembly on, the edge or mouth of the tubular element section (8), in the operative position of the spool with both halves mutually coupled, constituting a device regulating the distance between both halves.
