Abstract
A piping joint includes a male member or joint fastened to a female member or socket by locking pawls of a retainer sleeve onto pawl engaging portions. By pressing a flange by the tip ends of the pawls, the male member (joint) can be disengaged from the female member (socket) by reducing the diameter of the retainer sleeve and disengaging the pawls from the pawl engaging portions. A ring member is formed of an elastic material and is inserted between the retainer sleeve and a cylinder portion in a locked condition. A reduction of the diameter of the retainer sleeve is prevented by the presence of the ring member. Therefore, the connecting or detaching of the piping joint can be carried out in a condition where a holding force of the piping joint is maintained.
Claims17
A piping joint structure comprising:
- a female member having a fitting hole;
- a male member having a cylinder portion capable of being inserted into said fitting hole;
- a flange being provided on said cylinder portion;
- a retainer sleeve being capable of being enlarged and reduced between a large diameter and a smaller diameter, wherein said retainer sleeve is capable of being operatively engaged with said cylinder portion;
- a pawl projecting diametrically outwards from said retainer sleeve;
- a pawl engaging portion provided in at least one of said female member or said male member for locking said retainer sleeve, wherein said male member can be fastened to said female member by locking said pawl of said retainer sleeve onto said pawl engaging portion and pressing said flange by a tip end of said pawl;
- and
- a ring member capable of being inserted between said retainer sleeve and said cylinder portion in a locked condition, said ring member including a ring portion having a ring opening and a cap portion having a cap opening, wherein said cap opening is positioned substantially normal to said ring opening, wherein a reduction of the diameter of said retainer sleeve to said smaller diameter is prevented by the presence of said ring member and said ring member is constructed of an elastic material.
