[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figures 1 to 6 As shown,

[0028] A special-shaped heat exchange tube assembly that is easy to connect comprises: a plurality of one-way valves 1 and a plurality of special-shaped tubes 2 that are connected and communicated with each other, a connecting assembly 3 that can connect and fix the two is provided between the one-way valves 1 and the special-shaped tubes 2, the connecting assembly 3 comprises a connecting frame 31, the connecting frame 31 is provided with a first positioning frame 32 that can rotate relative to each other, the first positioning frame 32 is provided with a first positioning groove 321 that can position and allow the one-way valve 1 to be snapped in, a first adjusting assembly 33 that can adjust the inclination angle of the first positioning frame 32 relative to the connecting frame 31 is provided between the first positioning frame 32 and the connecting frame 31, a support frame 34 is connected to one side of the connecting frame 31, the support frame 34 is rotatably connected to the connecting frame 31, the end of the support frame 34 is connected to a second positioning frame 35, the second positioning frame 35 is provided with a second positioning groove 351 that can position and allow the special-shaped tube 2 to be snapped in, and a second adjusting assembly 36 that can adjust the inclination angle of the first positioning frame 32 relative to the connecting frame 31 is provided between the support frame 34 and the connecting frame 31.

[0029] When it is necessary to connect the special-shaped heat exchange tube assembly, the first positioning frame 32 is sleeved on the one-way valve 1, and then the special-shaped tube 2 connected to the one-way valve 1 is sleeved in the second positioning frame 35. The first positioning frame 32 and the second positioning frame 35 are respectively clamped and fixed in the first positioning groove 321 and the second positioning groove 351. Then, the first adjusting component 33 and the second adjusting component 36 are respectively operated to make the first positioning frame 32 rotate relative to the connecting frame 31, and the supporting frame 34 rotate relative to the connecting frame 31, so that the one-way valve 1 and the special-shaped tube 2 are connected at a preset angle and welded. The setting of the connecting component 3 makes it more convenient to connect the one-way valve 1 and the special-shaped tube 2, and can be used as a positioning tool for welding. At the same time, since the connecting component 3 fixes the one-way valve 1 and the special-shaped tube 2, it can reduce the vibration of the pipelines where the one-way valve 1 and the special-shaped tube 2 are respectively located, reduce the vibration of each pipeline when it is suspended, and make the connection of the special-shaped heat exchange tube assembly more stable.

[0030] The first adjustment assembly 33 includes a first rotating rod 331 rotatably connected to the connecting frame 31. A second rotating rod 332 is provided between the first rotating rod 331 and the first positioning frame 32, rotatably connected thereto. To adjust the first positioning frame 32, the second rotating rod 332 is rotated. Rotation of the second rotating rod 332 rotates the first rotating rod 331, which in turn rotates the first rotating rod 331, thereby adjusting the inclination angle of the first positioning frame 32 relative to the connecting frame 31.

[0031] The second rotating rod 332 includes a first rotating seat 3321 rotatably connected to the upper end of the first rotating rod 331. The upper end of the first positioning frame 32 is connected to the second rotating seat 3322. A first rod 3323 is disposed between the first rotating seat 3321 and the second rotating seat 3322, capable of being threadedly connected to the first and second rotating seats 3321 and 3322. By operating the first rod 3323 with a wrench, the first rod 3323 can be rotated relative to the first and second rotating seats 3321 and 3322, retracting into the first and second rotating seats 3321 and 3322, or extending outward from the first and second rotating seats 3321 and 3322, thereby facilitating adjustment of the inclination angle of the first positioning frame 32 relative to the connecting frame 31.

[0032] The first positioning frame 32 includes a first frame body 322, a first positioning slot 321 being provided in the middle of the first frame body 322, and upwardly extending connecting portions 323 being provided at the left and right ends of the first frame body 322. The connecting portions 323 are rotatably connected to the connecting frame 31. The connecting portions 323 are conveniently mounted on the rotating shaft of the connecting frame 31, facilitating the rotation of the first positioning frame 32 relative to the connecting frame 31.

[0033] The connecting portion 323 is connected to a rotating bracket 324 arranged in a triangle shape. Both sides of the lower end of the rotating bracket 324 are connected to the first positioning bracket 32 ​​and the connecting bracket 31 . The upper end of the rotating bracket 324 is rotatably connected to the second rotating seat 3322 .

[0034] When the second rotating seat 3322 moves, the upper end of the rotating bracket 324 moves, and the upper end of the rotating bracket 324 also moves relative to the second rotating seat 3322, so that the rotating bracket 324 drives the connecting portion 323 to move, thereby causing the first positioning frame 32 to rotate relative to the connecting frame 31.

[0035] The rotating bracket 324 is also provided with a rotating handle 325 that can be threadedly connected thereto. When the rotating handle 325 is rotated relative to the rotating bracket 324, the end of the rotating handle 325 abuts against or moves away from the outer side of the one-way valve 1. When the rotating handle 325 is tightened, its end abuts against the outer side of the one-way valve 1, further positioning and securing the installation.

[0036] The support frame 34 is provided with a slot 341 into which the connecting frame 31 can be inserted. The slot 341 is used for positioning and also facilitates the rotation of the support frame 34 .

[0037] The second adjustment assembly 36 includes a third rotating rod 361 rotatably connected to the connecting frame 31. A fourth rotating rod 362 is provided between the third rotating rod 361 and the support frame 34, and is rotatably connected to both. When the support frame 34 and the second positioning frame 35 need to be adjusted, the fourth rotating rod 362 is rotated. The rotation of the fourth rotating rod 362 drives the rotation of the third rotating rod 361, which in turn drives the rotation of the first rotating rod 331, thereby driving the rotation of the support frame 34 and the second positioning frame 35, thereby adjusting the inclination angle of the support frame 34 and the second positioning frame 35 relative to the connecting frame 31.

[0038] The third rotating rod 361 includes a third rotating base 3611 rotatably connected to the connecting frame 31. The free end of the fourth rotating rod 362 is rotatably connected to the fourth rotating base 3612. A second rod 3613 is disposed between the fourth rotating base 3612 and the third rotating base 3611, capable of being threadedly connected thereto. By operating the second rod 3613 with a wrench, the second rod 3613 can be rotated relative to the third and fourth rotating bases 3611 and 3612, allowing the second rod 3613 to retract into the third and fourth rotating bases 3611 and 3612, or extend outward from the third and fourth rotating bases 3611 and 3612, thereby facilitating adjustment of the inclination angle of the support frame 34 and the second positioning frame 35 relative to the connecting frame 31.

[0039] The second positioning frame 35 includes a base plate 352, with multiple support rods 353 connected to the left and right sides of the base plate 352. A mounting plate 354 is connected between the top ends of the support rods 353 on the same side. A downwardly extending connecting column 355 is connected to the mounting plate 354, and the lower end of the connecting column 355 is connected to the second frame 356. The second frame 356 is provided with a second positioning groove 351 for the special-shaped tube 2 to be inserted. The base plate 352 is also provided with a second positioning groove 351 for the special-shaped tube 2 to be inserted. The connecting column 355 is a column with a shock-absorbing spring or silicone pad to facilitate shock absorption. At the same time, the parallel arrangement of the second frame 356 and the base plate 352 facilitates positioning and fixing, making the installation and connection more stable.

[0040] The connecting frame 31 is C-shaped and is provided with a receiving groove 311 capable of accommodating the first positioning frame 32 to rotate therein, so as to facilitate connection and positioning.

[0041] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
