[0002] In modern buildings, industrial plants, underground parking garages, and other similar locations, ventilation systems are crucial for ensuring air circulation, environmental comfort, and the normal operation of equipment. Due to their weight, airflow impact, and the complexity of the installation environment, ventilation ducts place high demands on the stability, adaptability, and ease of installation of their supporting structures. Traditional supporting structures suffer from inconvenient adjustment, complex installation, and poor stability, making it difficult to meet the needs of diverse scenarios.

[0003] To address the aforementioned issues, the ventilation duct support structure must possess the ability to flexibly adjust the pipe diameter to adapt to ventilation ducts of different sizes; enable rapid and precise installation, reducing construction difficulty and time costs; provide stable and reliable support to cope with complex environments and changes in duct stress, ensuring the long-term stable operation of the ventilation system and improving the safety and reliability of ventilation systems in buildings or industrial sites.

[0004] Therefore, we propose a support structure for ventilation ducts. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0024] Example: A support structure for a ventilation duct, such as Figures 1-4As shown, the support includes a support plate 1, with several movable supports 2 movably disposed on the inner side of the support plate 1, and mounting flanges 3 movably disposed on both sides of the support plate 1. The support plate 1 is semi-circular in side view. Several mounting supports 4 are movably disposed on both sides of the bottom end of the support plate 1, and adjusting rods 5 are movably disposed on the inner side of the mounting supports 4. Several connecting holes 6 are opened on both sides of the support plate 1, and the connecting holes 6 engage with the mounting flanges 3. Several mounting holes 7 for connecting to the wall are opened on the outer side of the mounting flanges 3. This support structure adopts a combination design of "movable supports 2 + mounting supports 4 + adjusting rods 5", which has excellent stability and adaptability. The movable supports 2 on the inner side of the support plate 1 can be flexibly adjusted to adapt to ventilation ducts of different diameters. Its semi-circular structure cooperates with the reinforcing plate 10 to increase the contact area with the duct. The friction coating 11 on the surface of the reinforcing plate 10 further prevents the duct from sliding. The adjusting rod 5 in the mounting support 4 is threaded to the base plate 12, and together with the support spring 15 and the connecting rod 14, the height can be finely adjusted according to the actual installation environment. The top plate 13 is welded and fixed to the support plate 1 to ensure the overall structure is stable and can maintain a good support effect even in complex building environments or when the pipeline is subjected to changes in stress.

[0025] like Figures 1-4 As shown, the mounting flange 3 has a pipe insertion hole 8 on its surface, which corresponds to the support plate 1. The support plate 1 has a flow groove 9 on its inner side, which engages with the bottom end of the movable support 2. The movable support 2 is semi-circular in side view. Semi-circular reinforcing plates 10 are fixedly installed on both sides of the movable support 2, and the surface of the reinforcing plates 10 is coated with a friction coating 11.

[0026] like Figures 1-3 As shown, the mounting support 4 includes a base plate 12, which is threadedly connected to an adjusting rod 5. A fixing hole 16 is provided on one side of the base plate 12. A top plate 13 is movably mounted on one side of the top of the base plate 12. One side of the top plate 13 is welded and fixed to the outer side of the support plate 1. A connecting rod 14 is fixedly mounted on the inner side of the top plate 13. A support spring 15 is fixedly mounted on the top of the adjusting rod 5. The other side of the support spring 15 is connected and fixed to the bottom end of the connecting rod 14. The mounting flange 3 engages with the support plate 1 through a connecting hole 6. The outer mounting hole 7 facilitates fixing to the wall, enabling rapid structural installation and positioning. The pipe insertion holes 8 on the flange surface precisely correspond to the support plate 1, ensuring accurate installation of the ventilation duct and reducing installation errors and adjustment time. Simultaneously, the fixing holes 16 on the base plate 12 of the mounting support 4 can assist in secondary fixing, further enhancing the robustness of the connection between the structure and the wall. This modular and precise installation design significantly improves construction efficiency and reduces installation difficulty and cost.

[0027] Working Principle: During installation, the entire support structure is first fixed to the wall through the mounting holes 7 on the outside of the mounting flange 3. The flange and support plate 1 are then engaged and positioned using the connecting holes 6, ensuring accurate relative positioning. The ventilation duct is inserted into the pipe insertion hole 8 of the flange, aligning with the support plate 1. At this point, the movable support 2 slides within the flow groove 9, automatically adjusting its position according to the pipe diameter. The reinforcing plate 10 and its friction coating 11 tightly adhere to the pipe, providing anti-slip fixation. The adjusting rod 5 of the mounting support 4 can be rotated to adjust its height to accommodate different installation height requirements. During adjustment, the support spring 15 and connecting rod 14 work together to absorb the impact force during installation and provide cushioning. After adjustment, secondary reinforcement is achieved through the fixing holes 16 on the base plate 12. During use, when the ventilation duct vibrates or experiences force changes due to airflow, the elasticity of the movable support 2 and the friction coating 11 effectively buffer the vibration. The adjusting rod 5 and support spring 15 system of the mounting support 4 can adjust the support force in real time, maintaining duct stability and ensuring the safe operation of the ventilation system.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
