Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The utility model provides a water plastic hose joint, which comprises a joint 1 and a locking nut 2;
the inside passageway 13 that radially runs through that forms of joint 1, rivers circulate along passageway 13, joint 1 both ends are link 11, installation end 12 respectively, link 11 is including the grafting section 111 that is used for pegging graft the hose, the external screw thread section 112 that is used for connecting lock nut 2, grafting section 111 is located the tip of link 11, the last array of grafting section 111 is equipped with three external diameter and is greater than the cyclic annular flange 113 of hose internal diameter, the number of cyclic annular flange 113 can set up according to actual need, and cyclic annular flange 113 is connected with the internal surface interference of hose, when fixing hose 3, still plays the sealed effect in junction to prevent leaking, and cyclic annular flange 113 has increased the frictional force between joint 1 and hose 3 simultaneously, makes hose 3 be difficult for droing off, the tip of grafting section 111 is the toper, when pegging graft hose 3 on joint 1, the hose is propped open to conical grafting section 111 tip, meanwhile, the guiding effect is achieved, the inserting process is more convenient and labor-saving, the mounting end 12 surface of the joint 1 is provided with the mounting thread 121, the boss 14 is arranged between the external thread section 112 and the mounting thread 121 of the joint 1, the joint 1 can be fixed on a corresponding through hole by matching the nut with the mounting thread 121 in a corresponding specification, the nut and the boss 14 are clamped at two ends of the through hole, the mounting and fixing can be completed, and the mounting thread 121 can also be directly screwed into a threaded hole in a corresponding specification to fix the joint 1;
