Further, in the present invention, inner tube is metal tube, and outer tube is the one in PPR pipe or PE pipe, and during docking, direct metal pipe docks, and during use, current directly circulate from metal tube, anticorrosive, outside logical PPR pipe or the PE seal of tube, fungi-proofing effective.
According to below in conjunction with the accompanying drawing detailed description to the specific embodiment of the invention, those skilled in the art will become more apparent from the above-mentioned of the present invention and other purposes, advantage and feature.
Accompanying drawing explanation
Describe some specific embodiments of the present invention the most by way of example, and not by way of limitation in detail.Reference identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that what these accompanying drawings were not necessarily drawn to scale.In accompanying drawing:
Fig. 1 is the cross-sectional view figure of pipe joint structure according to an embodiment of the invention.
Wherein:
1, pipe connects male;11, male outer tube;12, male inner tube;13, male joint portion;2, pipe connects female;21, female outer tube;22, female inner tube;23, female joint portion;24, female extension.
Detailed description of the invention
Fig. 1 is the cross-sectional view of pipe joint structure according to an embodiment of the invention.
As shown in Figure 1, described pipe joint structure can include a kind of pipe joint structure in general manner, connect male 1 including the pipe docked mutually and pipe connects female 2, described pipe connects male 1 and includes that male outer tube 11 and male inner tube 12, the end of described male inner tube 12 have the male joint portion 13 being longer than described male outer tube 11;Described pipe connects female 2 and includes that female outer tube 21 and female inner tube 22, the end of described female outer tube 21 have the female extension 24 being longer than described female inner tube 22,
Wherein, the internal diameter of described female extension 24 is equal with the external diameter of described male outer tube 11, and the position that described female inner tube 22 is docked with described male joint portion 13 is female joint portion 23, and the internal diameter of described female joint portion 23 is equal to the external diameter of described male joint portion 13.The length of described male joint portion 13 generally can be positioned between 2mm to 4mm.
During assembling, by male joint portion 13, the most namely the extension of male inner tube 12 directly snaps in described female joint portion 23, closely cooperate between the two, air-tightness is good, then use in male outer tube 11 and female outer tube 21 joint the fixing connected mode needed to be fixed, the docking that pipe connects can be realized and fix.
In fact it is understandable that, in order to easy to assembly, the internal diameter of described female joint portion 23 can also be slightly larger than the external diameter of described male joint portion 13, so, pipe in male joint portion 13 docks fixing with female joint portion 23, not only ensure that air-tightness, additionally it is possible to improve stable connection degree to a certain extent.
Further, the internal diameter of described female joint portion 23 is less than the internal diameter of described female extension 24, and described pipe is positioned at the junction of described female joint portion 23 and described female extension 24 and is provided with step-like cementitious adhesive face in connecing the pipe of female 2.
Further, the shoulder height in described cementitious adhesive face is equal to the thickness of described male outer tube 11, and as considered the thickness of female inner tube 22, the shoulder height in described cementitious adhesive face can be slightly less than the thickness of described male outer tube 11, depending on practical situation.
Further, the male outer tube 11 that described pipe connects in male 1 is one-body molded with male inner tube 12, and the female outer tube 21 that described pipe connects in female 2 is one-body molded with female inner tube 22.
As used the connecting tube that is screwed to connect male 1 and pipe connects female 2, described female outer tube 21 and female inner tube 22 are arranged interior metal threaded or the most metal threaded.
In order to meet the design standard of running water pipe, can be metal tube by described male inner tube 12 and described female inner tube 22, male outer tube described in the present embodiment 11 and described female outer tube 21 use PPR pipe, described PPR pipe sweat soldering at described metal tube surface, is coated on the surface of described metal tube and constitutes described pipe and connect male 1 or described pipe connects female 2.In the present embodiment, inner tube is metal tube, and outer tube is PPR pipe, and during docking, direct metal pipe docks, and during use, current directly circulate from metal tube, anticorrosive, outside by PPR pipe, fungi-proofing effective.
Additionally, in order to realize rapid abutting joint, the global shape at the edge in described cementitious adhesive face can be may be designed as shaped form (not shown in figure, the edge in the cementitious adhesive face in the present embodiment accompanying drawing 1 is smooth periphery), the outer rim of described male outer tube 11 is the shaped form matched with described cementitious adhesive face, connects the male 1 rotation in described tube coupling female 2 for limiting described pipe.It addition, smooth edges if round, pipe connects male 1 and pipe connects and will necessarily produce relative rotation between female 2, will affect cementing effect when rotating, and curved edge just can effectively prevent pipe from connecing male 1 and pipe connects the rotation between female 2.
To sum up, pipe joint structure described by the present embodiment, male inner tube 12 can embed described female inner tube 22, male outer tube 11 is directly fixed or cementing with female outer tube 21 gradually compact form, butt junction location is convenient, assembling is simple, described male inner tube 12 and coordinating more closely between female inner tube 22, improves the air-tightness that pipe connects.
So far, those skilled in the art will recognize that, although the most detailed multiple exemplary embodiments illustrate and describing the present invention, but, without departing from the spirit and scope of the present invention, still can directly determine according to present disclosure or derive other variations or modifications of many meeting the principle of the invention.Therefore, the scope of the present invention is it is understood that and regard as covering other variations or modifications all these.
