Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology, specifically relating to a pipe fitting with an internal sliding groove. Background Technology

[0002] Finned tubes are a type of heat exchange element designed to improve heat exchange efficiency. Typically, fins are added to the surface of the heat exchange tube to increase its outer surface area, thereby improving heat exchange efficiency.

[0003] Conventional finned tubes are manufactured using flange welding or integral casting processes. During installation, the spacing must be strictly matched to the preset spacing of the piping system. In scenarios such as chemical pipeline renovation and waste heat recovery system expansion, on-site installation dimensional deviations often lead to pipes being unable to connect, forcing the project team to use customized pipe fittings or add transition connectors, significantly increasing construction costs and time. To address this, we have designed a pipe fitting with an internal groove to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0007] Preferably, the adjusting mechanism includes a circular rotating ring, which is sleeved on the outside of the circular heat sink and threadedly connected to the circular heat sink. One end of the circular rotating ring is rotatably connected to a circular sliding ring, and one end of the circular sliding ring is rotatably connected to a plurality of oblique rotating columns via a pin. One end of each oblique rotating column is rotatably connected to a circular sleeve, and a vertical limiting column is fixed inside the circular sleeve.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-6 A pipe fitting with an inner groove includes a circular heat dissipation pipe 1, a plurality of circular heat dissipation fins 2 are evenly distributed and fixed on the outer side of the circular heat dissipation pipe 1, and circular flange connecting pieces 3 are provided at both ends of the circular heat dissipation pipe 1. An internal extension heat dissipation pipe 4 is slidably connected inside the circular heat dissipation pipe 1. The end of the internal extension heat dissipation pipe 4 is close to the circular flange connecting piece 3 and is fixedly connected to the circular flange connecting piece 3. An adjustment mechanism for adjusting the position of the internal extension heat dissipation pipe 4 is provided on the outer side of the circular heat dissipation pipe 1.

[0023] The circular heat sink 1 has a horizontal rectangular groove inside, and multiple horizontal rectangular sliders are evenly distributed and fixed on the outside of the built-in extension heat sink 4. The circular heat sink 1 and the built-in extension heat sink 4 are slidably connected through the cooperation of the horizontal rectangular groove and the horizontal rectangular slider. The horizontal rectangular groove and the horizontal rectangular slider allow the built-in extension heat sink 4 to slide horizontally inside the circular heat sink 1, thereby allowing the distance between the two circular flange connecting pieces 3 to be adjusted so that the circular heat sink 1 can adapt to different length installation requirements.

[0024] The adjustment mechanism includes a circular rotating ring 5, which is sleeved on the outside of the circular heat sink 1 and threadedly connected to the circular heat sink 1. One end of the circular rotating ring 5 is rotatably connected to a circular sliding ring 7. One end of the circular sliding ring 7 is rotatably connected to a plurality of oblique rotating columns 8 via a pin. One end of the oblique rotating column 8 is rotatably connected to a circular sleeve 10. A vertical limiting column 9 is fixed inside the circular sleeve 10. A plurality of circular limiting holes adapted to the vertical limiting column 9 are evenly distributed on the outside of the built-in extended heat sink 4.

[0025] The circular heat sink 1 has a circular through hole inside. The vertical limiting post 9 is located inside the circular through hole and is slidably connected to the circular heat sink 1 through the circular through hole. The circular through hole allows the vertical limiting post 9 to slide inside the circular heat sink 1 so that the vertical limiting post 9 can enter the interior of the built-in extended heat sink 4, thereby restricting the movement of the built-in extended heat sink 4 inside the circular heat sink 1.

[0026] The outer side of the circular heat sink 1 is provided with an internal thread groove, and the inner side of the circular rotating ring 5 is provided with an internal thread groove. The circular heat sink 1 and the circular rotating ring 5 are connected by the mating of the internal thread groove and the external thread groove. By setting the internal thread groove and the external thread groove, the circular rotating ring 5 can rotate on the outside of the circular heat sink 1, thereby allowing the circular sliding ring 7 to move on the outside of the circular heat sink 1.

[0027] A T-shaped rotating ring 6 is fixed to one end of the circular sliding ring 7 near the circular rotating ring 5. A T-shaped rotating groove is provided inside the circular rotating ring 5. The T-shaped rotating ring 6 is located inside the T-shaped rotating groove and is rotatably connected to the circular rotating ring 5 through the T-shaped rotating groove. The T-shaped rotating groove allows the circular rotating ring 5 to rotate outside the T-shaped rotating ring 6.

[0028] Multiple horizontal moving blocks are evenly distributed and fixed inside the circular sliding ring 7. Horizontal moving slots adapted to the horizontal moving blocks are evenly distributed inside the circular heat sink 1. The circular sliding ring 7 and the circular heat sink 1 are slidably connected through the horizontal moving blocks and the horizontal moving slots, thereby allowing the circular sliding ring 7 to move laterally outside the circular heat sink 1. The movement of the circular sliding ring 7 is achieved by the oblique rotating column 8, which allows the vertical limiting column 9 to move vertically inside the circular heat sink 1. This allows the vertical limiting column 9 to enter the circular limiting hole of the built-in extended heat sink 4, thereby restricting the movement of the built-in extended heat sink 4 inside the circular heat sink 1.

[0029] Here, the circular rotating ring 5 is rotated, which allows the T-shaped rotating ring 6 to rotate inside the circular rotating ring 5. Through the threaded connection between the circular rotating ring 5 and the circular heat sink 1, the circular sliding ring 7 can move laterally outside the circular heat sink 1. The lateral movement of the circular sliding ring 7 allows the vertical limiting post 9 to slide vertically inside the circular heat sink 1 through the oblique rotating post 8. When the vertical limiting post 9 moves out of the interior of the built-in extended heat sink 4, the built-in extended heat sink 4 can move laterally inside the circular heat sink 1, thereby adjusting the position of the circular flange connecting piece 3. When the vertical limiting post 9 enters the interior of the built-in extended heat sink 4, the position of the circular flange connecting piece 3 is limited.

[0030] Working principle: When the installation position of the circular flange connecting piece 3 changes, the circular rotating ring 5 is rotated, which in turn allows the T-shaped rotating ring 6 to rotate inside the circular rotating ring 5. Through the threaded connection between the circular rotating ring 5 and the circular heat dissipation pipe 1, the circular sliding ring 7 can move laterally outside the circular heat dissipation pipe 1. The lateral movement of the circular sliding ring 7 causes the vertical limiting post 9 to slide vertically inside the circular heat dissipation pipe 1 through the oblique rotating post 8. When the vertical limiting post 9 moves out of the interior of the built-in extended heat dissipation pipe 4, the built-in extended heat dissipation pipe 4 can move laterally inside the circular heat dissipation pipe 1, thereby adjusting the position of the circular flange connecting piece 3. When the vertical limiting post 9 enters the interior of the built-in extended heat dissipation pipe 4, the position of the circular flange connecting piece 3 is limited.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
