Description

Technical Field

[0001] This utility model relates to the field of spiral duct installation technology, specifically to an air conditioning spiral duct that is easy to disassemble and assemble. Background Technology

[0002] Spiral duct is a thin-walled pipe made of metal strip rolled into a spiral seam. It is round, without welding, airtight, and watertight. It is mostly used for air supply and bulk material transportation and can replace traditional galvanized iron pipes. Flange connection is mostly used during installation.

[0003] Utility model patent CN217003513U discloses a central air conditioning spiral duct, including a first pipe, a first connecting flange fixedly installed at one end of the first pipe, a limit post fixedly installed on the outer wall of the first connecting flange, and a second connecting flange movably connected to the outer wall of the limit post; the second connecting flange has a limit hole inside, a threaded sleeve movably connected to the outer wall of the first pipe, a second pipe fixedly installed on the outer wall of the second connecting flange, and a threaded post movably connected to the outer wall of the second pipe. This allows the device to be easily disassembled and installed by the user, thereby improving the installation efficiency of the staff, avoiding cumbersome operations during installation, bringing convenience to the user, and improving the practicality of the device.

[0004] However, there are still some shortcomings in the above technical solution: When the above technical solution is used, the threaded column is rotated to make it threadedly connected with the threaded sleeve, so as to realize the convenient connection between the first pipe and the second pipe. However, if the threaded column wants to rotate, it must be rotated to the outside of the second pipe. The connection method can be a bearing connection, but the bearing is not very effective in resisting lateral tensile force, which can easily lead to the threaded column and the second pipe separating. Therefore, the existing technical solution needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide an air conditioning spiral duct that is easy to install and disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning spiral duct that is easy to assemble and disassemble, comprising a first duct and a second duct.

[0007] A flange is installed on the end of the first duct near the second duct, and a flange is installed on the end of the second duct near the first duct. A limiting post is provided on the flange that is inserted into the flange. A connecting ring is installed on the outside of the flange on the first duct and a connecting ring is installed on the outside of the flange on the second duct. Both the connecting ring and the connecting ring are threaded on their sidewalls, and an internal threaded sleeve is threaded onto the connecting ring.

[0008] By adopting the above technical solution, during use, after the first and second air ducts are connected to each other, the limiting post on flange one is inserted into flange two, so that connecting ring one and connecting ring two are aligned. Then, the internal threaded sleeve on connecting ring one is rotated, so that the internal threaded sleeve rotates between connecting ring one and connecting ring two to achieve the connection effect between connecting ring one and connecting ring two. During this process, connecting ring one and connecting ring two do not need to rotate, thus avoiding the situation of separation.

[0009] As a further embodiment of this utility model: a sealing ring groove 1 is provided on the side of flange 1 near flange 2, and a sealing ring groove 2 is provided on the side of flange 2 near flange 1. A sealing ring is installed between the sealing ring groove 1 and the sealing ring groove 2.

[0010] By adopting the above technical solution, during use, the sealing ring between sealing ring groove one and sealing ring groove two can seal the gap between flange one and flange two, reducing gas leakage.

[0011] As a further embodiment of this utility model: the flange 2 is also provided with a limiting hole, which is aligned with the limiting post.

[0012] By adopting the above technical solution, the design of the limiting hole facilitates the passage of the limiting post during use, and the limiting post and flange are used as a whole to limit the movement.

[0013] As a further embodiment of this utility model: a magnetic metal ring is installed on the side wall of the first connecting ring, and a magnet ring is installed on the side wall of the second connecting ring at a position aligned with the magnetic metal ring.

[0014] By adopting the above technical solution, the mutual attraction between the magnetic metal ring and the magnet ring during use avoids the need to constantly press against the first and second air ducts during installation, thus reducing the operation during installation.

[0015] As a further embodiment of this utility model: both the first connecting ring and the second connecting ring have a recessed notch on their sidewalls, and the recessed notch has a thread, with the internal thread sleeve threaded into the recessed notch.

[0016] By adopting the above technical solution, the design of the recessed notch during use prevents the internal threaded sleeve from rotating to the outside of connecting ring one and connecting ring two.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this air conditioning spiral duct is easy to disassemble and assemble.

[0018] The system is equipped with a first connecting ring, a second connecting ring, and an internal threaded sleeve. When the first duct and the second duct are aligned, the first connecting ring and the second connecting ring are also aligned. The limiting post on the first flange is inserted into the second flange to position the mating angle of the first connecting ring and the second connecting ring, so that the threads on the first connecting ring and the second connecting ring are properly mated. Finally, the internal threaded sleeve rotates between the first connecting ring and the second connecting ring to fix the first duct and the second duct, thus preventing the first connecting ring and the second connecting ring from falling off due to rotation.

[0019] In addition, the easy-to-disassemble air conditioning spiral duct is also equipped with magnetic metal rings and magnet rings. When connecting, the magnetic metal rings and magnet rings on connecting ring one and connecting ring two attract each other, avoiding the situation where there is a gap between connecting ring one and connecting ring two, which would prevent the inner thread sleeve from rotating.

[0025] Please see Figure 1-3 This utility model provides a technical solution: an air conditioning spiral duct that is easy to assemble and disassemble, comprising a first duct 1 and a second duct 2.

[0026] A flange 3 is installed at the end of the first duct 1 near the second duct 2, and a flange 4 is installed at the end of the second duct 2 near the first duct 1. A limiting post 5 is provided on the flange 3 and inserted into the flange 4. A connecting ring 7 is installed on the outside of the flange 3 on the first duct 1, and a connecting ring 8 is installed on the outside of the flange 4 on the second duct 2. Both the connecting ring 7 and the connecting ring 8 have threads on their side walls, and an internal threaded sleeve 9 is threaded onto the connecting ring 7.

[0027] Please see Figure 2 Furthermore, a sealing ring groove 301 is provided on the side of flange 3 near flange 4, and a sealing ring groove 401 is provided on the side of flange 4 near flange 3. A sealing ring 10 is installed between the sealing ring groove 301 and the sealing ring groove 401.

[0028] Please see Figure 2 Furthermore, a limiting hole 6 is also provided on flange 24, which is aligned with the limiting post 5;

[0029] Specifically, the limiting post 5 and the limiting hole 6 are provided in two sets, upper and lower, and the threads on the outer sides of the connecting ring 1 7 and the connecting ring 2 8 are also aligned with each other when the limiting post 5 and the limiting hole 6 are aligned, which facilitates the rotation of the internal thread sleeve 9.

[0030] Please see Figure 2 Furthermore, a magnetic metal ring 11 is installed on the side wall of the connecting ring 7, and a magnet ring 12 is installed on the side wall of the connecting ring 8 at a position aligned with the magnetic metal ring 11.

[0031] Please see Figure 1 and Figure 3 Furthermore, both the first connecting ring 7 and the second connecting ring 8 have a recessed notch on their sidewalls, and the recessed notch has a thread, with the internal threaded sleeve 9 threadedly connected to the recessed notch.

[0032] Working principle: When using this easy-to-assemble and disassemble air conditioning spiral duct, after the first duct 1 and the second duct 2 are aligned, the connecting ring 1 7 and the connecting ring 2 8 are also aligned. The limiting post 5 on the flange 1 3 is inserted into the flange 2 4 to position the mating angle of the connecting ring 1 7 and the connecting ring 2 8, so that the threads on the connecting ring 1 7 and the connecting ring 2 8 are properly mated. Finally, the inner thread sleeve 9 rotates between the connecting ring 1 7 and the connecting ring 2 8 to fix the first duct 1 and the second duct 2, avoiding the situation where the connecting ring 1 7 and the connecting ring 2 8 will fall off due to rotation. During mating, the magnetic metal ring 11 and the magnet ring 12 on the connecting ring 1 7 and the connecting ring 2 8 attract each other, preventing the inner thread sleeve 9 from being unable to rotate due to gaps between the connecting ring 1 7 and the connecting ring 2 8.
