Summary of the invention:
The technical problem to be solved in the present invention is, provides a kind of and not only can be used as female joint, but also can be used as tool joint pin, the rapid pipe joint that is convenient for people to install and use.
Technical solution of the present invention is, provide a kind of rapid pipe joint with following structure: comprise joint body, spring and be enclosed within the overcoat on joint body, the left part of joint body is provided with outside thread, the right part of joint body is provided with annular boss, the right side of annular boss is provided with seal ring, the left end of outer casing inner wall is provided with annular rib, the right-hand member of overcoat is enclosed within on annular boss, joint body is provided with back-up ring, annular rib left side withstands on back-up ring, spring housing is on joint body, and spring top is between annular rib and annular boss, wherein, edge on the right side of overcoat is circumferentially evenly equipped with a plurality of pull bars, the right-hand member of each pull bar is equipped with overhead kick, the outer corresponding position putting between adjacent two pull bars is equipped with the first axial notch, the axial length of the first axial notch is greater than the length of pull bar, the radial depth of the first axial notch is greater than the thickness of pull bar, the width of the first axial notch is greater than the width of the pull bar of twice, one side of each the first axial notch bottom is also provided with second axial notch that can insert for overhead kick, the axial length of the second axial notch equates with the axial length of the first axial notch, the left side of the first axial notch bottom is provided with the transverse groove communicating with the second axial notch, the radial depth of transverse groove equates with the radial depth of the second axial notch, the distance of the right flank of transverse groove and the right side of overcoat is less than the length of pull bar, transverse groove right flank is provided with the locating slot that can enter for overhead kick.
Adopt after above structure, compared with prior art, rapid pipe joint of the present invention has the following advantages: be divided into female joint from the rapid pipe joint of prior art and tool joint pin is different, the present invention need not distinguish female joint and tool joint pin, in other words, the present invention can be used as female joint, can be used as again tool joint pin, when two rapid pipe joint docking of the present invention, as long as be inserted into respectively in the second axial notch of the other side by a plurality of pull bars, annular boss in two rapid pipe joints can first contact, be inserted at the end, spring contraction, then rotate round about two overcoats, overhead kick is entered in transverse groove, at this moment, under the elastic force effect of spring, overhead kick meeting enters in locating slot, thereby complete the docking of two rapid pipe joints of the present invention, facilitated installing and using of people.
Accompanying drawing explanation:
Fig. 1 is the perspective view of rapid pipe joint of the present invention;
Fig. 2 is that the master of rapid pipe joint of the present invention looks sectional structure schematic diagram;
Perspective view when Fig. 3 is two rapid pipe joints connections of the present invention;
Master when Fig. 4 is two rapid pipe joints connections of the present invention looks sectional structure schematic diagram.
Embodiment:
Below in conjunction with the drawings and specific embodiments, rapid pipe joint of the present invention is described further:
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, in this embodiment, rapid pipe joint of the present invention comprises joint body 13, spring 14 and be enclosed within the overcoat 2 on joint body 13, the left part of joint body 13 is provided with outside thread 1, the right part of joint body 13 is provided with annular boss 7, the right side of annular boss 7 is provided with seal ring 8, the left end of overcoat 2 inwalls is provided with annular rib 12, the right-hand member of overcoat 2 is enclosed within on annular boss 7, joint body 13 is provided with back-up ring 11, annular rib 12 left sides withstand on back-up ring 11, spring 14 is enclosed within on joint body 13, and spring 14 withstands between annular rib 12 and annular boss 7, edge on the right side of overcoat 2 is circumferentially evenly equipped with three pull bars 9, the right-hand member of each pull bar 9 is equipped with overhead kick 10, corresponding position on overcoat 2 between adjacent two pull bars 9 is equipped with the first axial notch 6, the axial length of the first axial notch 6 is greater than the length of pull bar 9, the radial depth of the first axial notch 6 is greater than the thickness of pull bar 9, the width of the first axial notch 6 is greater than the width of the pull bar 9 of twice, one side of each the first axial notch 6 bottom is also provided with second axial notch 5 that can insert for overhead kick 10, the axial length of the second axial notch 5 equates with the axial length of the first axial notch 6, the left side of the first axial notch 6 bottoms is provided with the transverse groove 3 communicating with the second axial notch 5, the radial depth of transverse groove 3 equates with the radial depth of the second axial notch 5, the distance of the right side of the right flank of transverse groove 3 and overcoat 2 is less than the length of pull bar 9, transverse groove 3 right flanks are provided with the locating slot 4 that can enter for overhead kick 10.
