摘要:
A telescopic pivotal pipe joint for use in a fluid transporting pipe system such as water transporting pipe system installed under the ground is disclosed. The joint has a first pipe member including a semi-spherical inner peripheral face, a second pipe member including a semi-spherical pipe portion projecting radially outward and sidable along the semi-spherical inner peripheral face of the first pipe member, the second pipe member being slidably engaged within the first pipe member, and a third pipe member telescopically sidable in an axial direction and engaged on a straight pipe portion co-extensive with the semi-spherical pipe portion of the second pipe member. The semi-spherical pipe portion of the second pipe member defines an annular groove, into which one end of the third pipe member comes into engagement along the axial direction when the second pipe member and the third pipe member are contracted maximally relative to each other.
