The technical scheme provided by this disclosed embodiment can include the following benefits：
1, the water heating pipe fittings connection structure of the utility model, structure is relatively simple, the connection side between inner tube and outer tube
Just, and the intensity of connection and reliability are higher.
It should be understood that above general description and following detailed description is only exemplary and explanatory, not
The disclosure can be limited.
Description of the drawings
Fig. 1 is the structural schematic diagram of water heating pipe fittings connection structure in embodiment.
Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Embodiment one：It is as shown in Figure 1, the present embodiment be a kind of water heating pipe fittings connection structure, including inner tube 1, outer tube 2 with
And connecting tube 3, one end of the outer tube 2 are sheathed on outside one end of the inner end 1, the connecting tube 3 is set to said inner tube 1 and institute
Between stating outer tube 2, it is arranged with left casing 4 and right casing 5, said inner tube 1 and the outer tube 2 respectively in the connecting tube 3
One end of connection is inserted into the left casing 4 from the left end of the connecting tube 3 and is threadedly coupled with the left casing 4, described outer
One end that pipe 2 is connect with said inner tube 1 is inserted into the right casing 5 and 5 spiral shell of right casing from the right end of the connecting tube 3
Line connects, and the left convex being recessed inwardly for being positioned to the left casing 4 is provided in the left end of the connecting tube 3
301 are played, the right convex being recessed inwardly for being positioned to the right casing 5 is provided in the right end of the connecting tube 3
Play 302.
The water heating pipe fittings connection structure of the present embodiment, structure is relatively simple, easy to connect between inner tube 1 and outer tube 2,
And the intensity and reliability connected is higher, and the case where be less prone to leakage.
Further, the positioning convex platform 303 extended inwardly is provided in the intermediate inner wall of the connecting tube 3, it is described outer
The end of pipe 2 is against on the right side of the positioning convex platform 303, the left casing 4 be limited at the left positioning protrusion 301 with
Between the positioning convex platform 303, it is convenient for the location and installation of outer tube 2 with this, and can avoid the axial movement of the left casing 4,
And then the reliability of water heating pipe fittings connection structure can be improved.
Further, the inner wall of the outer tube 2 is provided with the positioning extended inwardly and arches upward 201, the end of said inner tube 1
Portion be against the positioning arch upward 201 left side on, be convenient for the location and installation of said inner tube 1 with this, effectively improve inner tube 1 with it is outer
The efficiency that pipe 2 connects, and can avoid the axial movement of inner tube 1 to a certain extent.
Preferably, it is connect on the outer surface of one end with the outer tube 2 in said inner tube 1 and offers an at least annular slot
