Each firm nut front inner wall be provided with the outer race section stage on the internal thread of external thread spiro fastening, on the inwall of rear end be one with stage after the internal conical surface of outer conical surface complementation;
Each bushing pipe is designed to the external diameter of internal diameter more than or equal to installation pipeline, and its length is greater than the length of interior cover portion shoulder hole, and it can be positioned at shoulder hole in the mode of being inserted in pipeline to be installed;
Described pad is two, is installed in separately between the internal projecting ring and bushing pipe of internal screw thread joint.
The rapid pipe joint of above-mentioned a kind of liquid line, wherein, the outer conical surface after the stage of described external screw thread joint is provided with grooving longitudinally.
The rapid pipe joint of above-mentioned a kind of liquid line, wherein, the outer conical surface of described external screw thread joint is to extend to aperture position thereafter after outer race section circle stage always, and forms angle less than 30 ° with inwall.
The rapid pipe joint of above-mentioned a kind of liquid line, wherein, described pad is the soft metal pad.
The beneficial effects of the utility model are: the rapid pipe joint of a kind of liquid line of the utility model has externally threaded external screw thread joint owing to having set up, it screws togather with the internal screw thread joint that has internal thread, saved great amount of manpower, need or not the pipeline port is welded when mounted at pipeline port hank knotting tooth yet.Simultaneously, the rapid pipe joint of this liquid line also is provided with firm nut and bushing pipe, makes that the rapid pipe joint of this liquid line is not yielding, becomes flexible, and firm performance is good, can bear stronger pulling force.
Description of drawings
Fig. 1 is the sectional drawing of the rapid pipe joint of a kind of liquid line of the utility model.
Embodiment
Be described further below in conjunction with the rapid pipe joint of accompanying drawing a kind of liquid line of the utility model.
See also Fig. 1, the rapid pipe joint of a kind of liquid line of the utility model comprises internal screw thread joint 1, a pair of hollow external screw thread joint 2, a pair of firm nut 3, a pair of bushing pipe 4 and a pair of pad 5, wherein:
Internal screw thread joint 1 has an internal projecting ring on inwall, respectively be provided with internal thread on the inwall of internal projecting ring both sides.
Each hollow external screw thread joint 2 comprises one by the hexagon nut of an evagination intermediate portion 22 that constitutes and the outer race section 21 that is positioned at its both sides, 23, interior cover portion 21 has the shoulder hole of an aperture greater than the internal diameter of hollow external screw thread joint 2, on the periphery wall of interior cover portion 21, be provided with screw thread, on the pipeline 6 that needs to install about the mode that the screw thread that external screw thread joint 2 can be by perisporium and the internal screw thread joint of both sides screw togather is set in, outer race section 23 has the externally threaded round stage that is provided with that is connected with intermediate portion 22 1 sidewalls, after this circle stage, be connected with an outer conical surface, outer conical surface is to extend to aperture position thereafter after outer race section 23 circle stages always, and forms angle less than 30 ° with inwall.This outer conical surface is provided with grooving 24 longitudinally, this grooving 24 be used for following will describe in detail under the effect of tightening up of firm nut 3, can make the wall distortion of the outer conical surface of external screw thread joint 2, wrap, can strengthen the resistance to tension of this rapid pipe joint and pipeline 6 in the pipeline 6 that will install herein.
