Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to an anti-eccentric installation structure for HVAC pipelines. Background Technology

[0002] In the field of modern building engineering, HVAC (Heating, Ventilation, and Air Conditioning) is one of the core systems for ensuring indoor environmental comfort. It undertakes key functions such as heating, ventilation, and air conditioning within buildings, and its operational performance directly affects the quality of life of residents, work efficiency, and the stability of industrial production. Whether it is a residential building, a commercial complex, an office building, an industrial plant, or a medical facility, all types of buildings rely on a well-designed HVAC system to maintain suitable temperature, humidity, and air quality.

[0003] A search revealed CN221547976U, which discloses a heating and ventilation (HVAC) pipe for HVAC engineering. The pipe includes a main body and a fastening mechanism. Both ends of the main body have connection ports, and a fastening mechanism is located at one end. The fastening mechanism includes a fixing sleeve and a positioning plate. The front end of the fixing sleeve fits against the inner surface of the connection port and is fixedly connected. The other end of the fixing sleeve is fixedly connected to the main body. An inner cavity is formed between the inner surface of the middle portion of the fixing sleeve and the main body, and a flexible plate is placed within this cavity. The flexible plate is fitted over the main body. An opening is provided on the fixing sleeve, and a bolt is fitted into the opening. The advantages of this invention are: the fastening mechanism uses bolts to press the flexible plate firmly, preventing the main body of the HVAC pipe from shaking or vibrating; the positioning plate positions the two main bodies of the HVAC pipe, preventing displacement between them, and the connection is relatively simple.

[0004] When using the above-mentioned pipelines, it is common to encounter positional errors in pipeline installation, resulting in eccentric installation and excessive stress at the joints. In severe cases, this can lead to production safety accidents such as gas leakage due to disconnection. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model proposes an anti-eccentric installation structure for HVAC pipelines to solve the eccentricity problem that may occur during pipeline installation.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An anti-eccentricity installation structure for HVAC ducts includes a protective plate. A bracket is fixedly connected to the outer wall of the protective plate. A sliding groove is provided inside the bracket. A motor is fixedly connected to the outer wall of the bracket. A rotating column is fixedly installed at the output end of the motor. A connecting plate is fixedly connected to the outer wall of the rotating column. A pull plate is rotatably connected to the outer wall of the connecting plate. A connecting bracket is fixedly connected to the outer wall of the pull plate. A second bracket is fixedly connected to the outer wall of the connecting bracket. A limit block is fixedly connected to the outer wall of the second bracket. A pipe assembly is provided on the outer wall of the limit block. The pipe assembly is used to transport heating.

[0008] Preferably, the pipe assembly includes a connecting pipe, the outer wall of which is disposed on the outer wall of the limiting block, and a conveying pipe is disposed on the outer wall of the connecting pipe.

[0009] Preferably, the outer wall of the second bracket is slidably connected to the inner wall of the groove, and the outer wall of the limiting block is slidably connected to the upper surface of the protective plate.

[0010] Preferably, a retaining plate is attached to the outer wall of the connecting tube, a release post is fixedly connected to the outer wall of the retaining plate, a release block is fixedly connected to the outer wall of the release post, a limit plate is attached to the outer wall of the release block, a cavity is opened inside the connecting tube, a column is fixedly connected to the outer wall of the limit plate, a top plate is fixedly connected to the outer wall of the column, and a spring is fixedly connected to the outer wall of the limit plate.

[0011] Preferably, the outer wall of the release block is slidably connected to the inside of the connecting pipe, and the outer wall of the column is slidably connected to the inner wall of the connecting pipe.

[0012] Preferably, the outer wall of the top plate is slidably connected to the inner wall of the cavity, and the outer wall of the spring is fixedly connected to the inner wall of the cavity.

[0013] Preferably, the outer wall of the limiting plate is slidably connected to the inner wall of the cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model's anti-eccentricity installation structure for HVAC ducts are:

[0015] First, the motor drives the rotating column to rotate, which in turn drives the connecting plate to rotate, thereby pulling the pull plates on both sides to move. This causes the connecting brackets and brackets on both sides to move towards each other and then drive the limit blocks to move towards each other and towards the center. This achieves the effect of avoiding poor sealing caused by installation eccentricity and improving installation efficiency.

[0016] Second, insert the clamping plate and release column into the connecting pipe, push the limiting plate upward along the inclined surface of the release column, and drive the column and top plate upward, so that the limiting plate penetrates into the cavity and compresses the spring. Through the spring's rebound, the limiting plate locks the spring. When it is necessary to remove it, continue to push the release column inward and move the release block simultaneously. Through the reverse inclined surface of the release block, the release column and clamping plate can be removed as a whole. This achieves the effect of making the disassembly process simple and quick when the pipeline has problems such as blockage or damage and needs to be repaired or replaced.

Detailed Implementation

[0022] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] Please refer to the following specific implementation method for an anti-eccentric installation structure for HVAC ducts. Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a protective plate 1, a bracket 2 fixedly connected to the outer wall of the protective plate 1, a sliding groove 3 inside the bracket 2, a motor 4 fixedly connected to the outer wall of the bracket 2, a rotating column 5 fixedly installed at the output end of the motor 4, a connecting plate 6 fixedly connected to the outer wall of the rotating column 5, a pull plate 7 rotatably connected to the outer wall of the connecting plate 6, a connecting bracket 8 rotatably connected to the outer wall of the pull plate 7, a second bracket 9 fixedly connected to the outer wall of the connecting bracket 8, a limit block 10 fixedly connected to the outer wall of the second bracket 9, and a pipe assembly provided on the outer wall of the limit block 10 for conveying heating.

[0024] Through the above technical solution, the starting motor 4 drives the rotating column 5 to rotate, which in turn drives the connecting plate 6 to rotate, thereby pulling the pull plates 7 on both sides to move towards the center. The protective plate 1 ensures the stability of the pipe assembly during use and prevents the motor 4 from being displaced under force. The first bracket 2 supports and restricts the rotating column 5, ensuring that the rotating column 5 will not be displaced when driven by the motor 4. This drives the connecting brackets 8 and the second bracket 9 on both sides to move towards the center, which in turn drives the limiting block 10 to move towards the center, clamping the pipe assembly. The second bracket 9 slides on the inner wall of the slide groove 3, ensuring that the connecting brackets 8 and the second bracket 9 can only make linear linear movements and will not rotate when pulled by the pull plate 7. In addition, there is enough distance between the pipe assembly and the first bracket 2 for connecting other pipes, thereby avoiding poor sealing caused by installation eccentricity and improving installation efficiency.

[0025] The pipeline assembly includes a connecting pipe 11, the outer wall of which is disposed on the outer wall of the limiting block 10, and a conveying pipe 12 is disposed on the outer wall of the connecting pipe 11.

[0026] Through the above technical solution, the heating gas enters through the delivery pipe 12 and is then delivered into the connecting pipe 11, and then directly delivered through the connection of the connecting pipe 11 with other pipes.

[0027] The outer wall of bracket 29 is slidably connected to the inner wall of the slide groove 3, and the outer wall of the limiting block 10 is slidably connected to the upper surface of the protective plate 1.

[0028] Through the above technical solution, the slide groove 3 restricts the support 9 to move linearly, and at the same time drives the spring 19 to move linearly. During installation, there will be no air leakage due to angular deviation. The fit between the limit block 10 and the protective plate 1 further ensures that the limit block 10 and the support 9 can only move linearly.

[0029] A retaining plate 13 is attached to the outer wall of the connecting pipe 11. A release post 14 is fixedly connected to the outer wall of the retaining plate 13. A release block 15 is fixedly connected to the outer wall of the release post 14. A limiting plate 17 is attached to the outer wall of the release block 15. A cavity 16 is opened inside the connecting pipe 11. A column 18 is fixedly connected to the outer wall of the limiting plate 17. A top plate 20 is fixedly connected to the outer wall of the column 18. A spring 19 is fixedly connected to the outer wall of the limiting plate 17.

[0030] Using the above technical solution, the release block 15 is pulled back, and then the clamping plate 13 and the release column 14 are inserted into the interior of the connecting pipe 11. Since the outer wall of the release column 14 is provided with a slope, it will first push the limiting plate 17 to move upward along the slope of the release column 14, and drive the column 18 and the top plate 20 to move upward, so that the limiting plate 17 penetrates into the interior of the cavity 16 and compresses the spring 19. Then, through the rebound of the spring 19, the limiting plate 17 will lock the spring 19 and fix it. When it is necessary to remove it, the release column 14 is continuously pushed inward and the release block 15 is moved simultaneously. Through the reverse slope of the release block 15, the release column 14 and the clamping plate 13 are removed as a whole, so that when the pipeline has problems such as blockage or damage and needs to be repaired or replaced, the disassembly process becomes simple and quick.

[0031] The outer wall of the release block 15 is slidably connected to the inside of the connecting pipe 11, and the outer wall of the column 18 is slidably connected to the inner wall of the connecting pipe 11.

[0032] Through the above technical solution, the connection tube 11 restricts the insertion of the card plate 13, the release column 14 and the release block 15 into the connection tube 11, allowing them to enter horizontally. The connection tube 11 also restricts the column 18 to move vertically up and down when it is driven by the limiting plate 17.

[0033] The outer wall of the top plate 20 is slidably connected to the inner wall of the cavity 16, and the outer wall of the spring 19 is fixedly connected to the inner wall of the cavity 16.

[0034] Through the above technical solution, the cavity 16 restricts the movement of the top plate 20, ensuring that it can only move up and down and preventing the column 18 from rising too high. The two ends of the spring 19 are connected, allowing the spring 19 to push the limiting plate 17 to move and engage the release block 15.

[0035] The outer wall of the limiting plate 17 is slidably connected to the inner wall of the cavity 16.

[0036] Through the above technical solution, the cavity 16 restricts the movement of the limiting plate 17, ensuring that the limiting plate 17 will not rotate when it rises, thus preventing angular deviation from affecting normal use.

[0037] Its working principle is as follows: When installation is required, the motor 4 drives the rotating column 5 to rotate, which in turn drives the connecting plate 6 to rotate, thereby pulling the pull plates 7 on both sides to move towards the center, thereby driving the connecting brackets 8 and bracket 9 on both sides to move towards the center, and in turn driving the limiting block 10 to move towards the center, clamping the pipe assembly, and leaving enough distance between the pipe assembly and bracket 2 for connecting other pipes, thereby avoiding poor sealing caused by installation eccentricity and improving installation efficiency;

[0038] When the connected pipe needs to be installed, insert the clamping plate 13 and the release column 14 into the interior of the connecting pipe 11. Since the outer wall of the release column 14 is provided with a slope, it will first push the limiting plate 17 to move upward along the slope of the release column 14, and drive the column 18 and the top plate 20 to move upward, so that the limiting plate 17 penetrates into the interior of the cavity 16 and compresses the spring 19. Then, through the rebound of the spring 19, the limiting plate 17 will lock the spring 19 and fix it. When it needs to be removed, continue to push the release column 14 inward and move the release block 15 at the same time. Through the reverse slope of the release block 15, the release column 14 and the clamping plate 13 can be removed as a whole, so that when the pipe has problems such as blockage or damage and needs to be repaired or replaced, the disassembly process becomes simple and quick.

[0039] This means that the HVAC duct not only avoids poor sealing caused by misaligned installation and improves installation efficiency, but also makes the disassembly process simple and quick when the duct needs to be repaired or replaced due to blockage or damage.

[0040] It should be noted that, although specific 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 variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
