(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of pipe joint, it comprises joint body (1), positioning joint (2) and fixing-assembly (3), the two ends of this joint body (1) are provided with tapped hole (11), in tapped hole (11), be provided with directional post (12) and sealing gasket (13), the internal orifice dimension of the external diameter of this directional post (12) and institute's connecting tube is Spielpassung; Positioning joint (2) comprises thread section (21), smooth section (22) and positive stop end (23), the through hole (212) that this thread section (21) is provided with the outside thread (211) that matches with tapped hole (11) and matches with institute connecting tube external diameter; Fixing-assembly (3) comprises position limit cycle (31), U-shaped connecting rod (32), retainer ring (33) and bolt (34), position limit cycle (31) is connected by U-shaped connecting rod (32) with retainer ring (33), and the external diameter of the internal diameter of this position limit cycle (31) and smooth section (22) matches; Retainer ring (33) is two half-turn compositions, and is connected by bolt (34).
Wherein, directional post (12) is cone shape.
Wherein, between the thread section (21) of positioning joint (2) and smooth section (22), be provided with hexagonal shell of column (24).
Wherein, retainer ring (33) inwall of fixing-assembly (3) is provided with anti-slip tank.
Wherein, retainer ring (33) inwall of fixing-assembly (3) is provided with protective pad (35), and this protective pad (35) is made up of rubber material.
(3) beneficial effect
Compared with prior art, the directly smooth pipeline of jointing end of the utility model; Wherein, directional post is arranged to cone shape, can more effective leading pipe joint connection puts in place; Hexagonal shell of column is set on positioning joint, can connects and put in place by pipe joint by tightening positioning joint; At the retainer ring inwall of the fixing-assembly chute of setting up defences, can effectively increase the friction factor between retainer ring inwall and pipeline, prevent that pipe joint and pipeline from departing from; And at the retainer ring inwall of fixing-assembly, protective pad is set, can effectively reduce the wearing and tearing at retainer ring and tube contacts position; In addition, make protective pad by rubber material, can protect those pipelines of being made by plastic material (as PE pipe, plastic tube etc.).
