A kind of transit joint of body
The present invention relates to a kind of transit joint, especially relate to a kind of transit joint of body.
Have a kind of transit joint of body to serve as connection between the body, it comprises matrix, and an end of matrix is provided with is with externally threaded joint, the other end of matrix is provided with cutting ferrule, joint, matrix and cutting ferrule three in one are provided with, and cutting ferrule is provided with U type cartoon hole, is used to install U type card.In use, be with externally threaded joint to be screwed into body fully after, therefore the through hole that may occur on the cutting ferrule is not corresponding with its supporting body through hole, can't insert U type card.Need externally threaded joint is oppositely back-outed a bit for this reason, make the through hole on the cutting ferrule corresponding fully with supporting body through hole, inserting the U type fastens, though this kind way can make the two ends of transit joint all connect with body, but what this moment, joint and body can become because oppositely back-out is loosening, and its sealing is influenced.At some special occasions, the connection sealing requirements of body is than higher.In the as installed process, just the transit joint of the various different sizes of needs configuration adapts to the connection between the different bodys, and cost is than higher.
Summary of the invention
Technical problem to be solved by this invention provides the lead to the hole site transit joint of adjustable body as required on a kind of cutting ferrule
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of transit joint of body, comprise matrix, described matrix one end is set with is with externally threaded joint, it also includes cutting ferrule, cutting ferrule is provided with U type cartoon hole, and described cutting ferrule comprises first draw-in groove and first snap ring, and the described matrix the other end is provided with second draw-in groove and second snap ring, described first draw-in groove cooperates with described second snap ring, and described second draw-in groove cooperates with described first snap ring.
Described joint and described matrix are wholely set.
Be provided with inner hexagonal hole in the described matrix.
Described matrix outer fixing has the outer-hexagonal nut.
Compared with prior art, advantage of the present invention cooperates with second snap ring owing to first draw-in groove, second draw-in groove cooperates with first snap ring, make cutting ferrule be socketed on the matrix, simultaneously cutting ferrule can freely rotate in that matrix is enterprising, when joint with after body is connected, position that can free adjustment U type cartoon hole, U type cartoon hole on the cutting ferrule and the through hole on being connected body complete corresponding after, can insert U type card cutting ferrule and connected body are fixed.
Be provided with inner hexagonal hole in the matrix, when transit joint is installed, because it is narrower and small to be mounted the space at body place, directly twist transit joint with spanner and can be difficult to operation, inner hexagonal hole is set in the matrix, can operates by inner hexagon spanner, relatively convenient.
The matrix outer fixing has the outer-hexagonal nut, also can transit joint be installed with spanner.
