[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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a central air conditioning duct hanger includes a truss 11, with hangers 12 installed on both sides of the truss 11; a first clamping plate 13 is fixedly connected to the top of the truss 11, and a second clamping plate 14 is slidably connected to the top of the truss 11; multiple first through holes 16 are opened on both sides of the first clamping plate 13 and the second clamping plate 14, and long bolts 15 are installed inside the first through holes 16; four hangers 12 are provided, and multiple second through holes 42 are opened at the ends of the truss 11 and at corresponding positions of the hangers 12; the hangers 12 pass through the second through holes 42, and external threads are opened on the surface of the hangers 12, with nuts 41 threaded onto the external threads;

[0024] In use, the operator places the duct above the truss 11, between the first clamping plate 13 and the second clamping plate 14. Then, the long bolt 15 is passed through the first through hole 16 on the first clamping plate 13 and the second clamping plate 14 to clamp and fix the duct. The second clamping plate 14 and the first clamping plate 13 cooperate to fix the duct. With the above structure, the second clamping plate 14 can move to adapt to ducts of different widths, improve the adaptability range, and facilitate the operator's installation.

[0025] During installation, the hanger 12 is mounted on the wall with fasteners. The hanger 12 has external threads and passes through the second through hole 42 on the truss 11. The truss 11 is locked and fixed with nuts 41 to fix the truss 11. This allows the height of the truss 11 to be adjusted to match the height of the air duct and improve its applicability.

[0026] Furthermore, such as Figure 1-5As shown, the first clamping plate 13 and the second clamping plate 14 are each provided with a support plate 21 on the side close to each other. A rack 25 is fixedly connected to the top of the support plate 21. The top of the first clamping plate 13 and the second clamping plate 14 are rotatably connected to a rotating shaft 22. A fixed arm 23 is fixedly connected to the rotating shaft 22. A gear 24 is fixedly connected to the rotating shaft 22 at the position corresponding to the rack 25. The gear 24 and the rack 25 mesh with each other.

[0027] During installation, as the first clamping plate 13 and the second clamping plate 14 close, the support plate 21 will first contact the air duct, and the compression will push the support plate 21 and the rack 25 to move. The rack 25 and the gear 24 mesh, and the movement of the rack 25 will cause the gear 24, the rotating shaft 22 and the fixing arm 23 to rotate. The fixing arm 23 is located above the air duct, and its rotation fixes the air duct from above, thereby improving the fixing effect of the air duct and improving stability. The support arm 32 is fixedly connected to the first clamping plate 13 and the second clamping plate 14, and the guide rod 31 is slidably connected to the support arm 32, thereby improving the stability of the support plate 21.

[0028] Furthermore, such as Figure 1-5 As shown, support arms 32 are fixedly connected to both sides of the first clamping plate 13 and the second clamping plate 14. A guide rod 31 is fixedly connected to the side of the support plate 21. The guide rod 31 passes through the support arm 32 and is slidably connected to it. A through groove is opened at the top of the first clamping plate 13 and the second clamping plate 14 at the position corresponding to the rack 25. The rack 25 passes through the through groove. A rubber pad 5 is fixedly connected to the top of the truss 11. The rubber pad 5 is located between the first clamping plate 13 and the second clamping plate 14. A spring 6 is sleeved on the guide rod 31. The two ends of the spring 6 are fixedly connected to the support arm 32 and the support plate 21, respectively.

[0029] During use, a rubber pad 5 is fixed to the top of the truss 11. The rubber pad 5 is used to pad the bottom of the air duct. The elastic structure of the rubber pad 5 can play a certain role in shock absorption. A spring 6 is fixed between the support arm 32 and the support plate 21. The spring 6 is used to drive the support plate 21 to move and reset, so that the support plate 21 can be reset and the fixed arm 23 can be kept in the open state.

[0030] Furthermore, such as Figure 1-5 As shown, a slide rail 7 is fixedly connected to the top of the truss 11, and the slide rail 7 and the bottom of the second clamping plate 14 are slidably connected. In use, the connection between the slide rail 7 and the second clamping plate 14 is relied upon to improve stability.

[0031] Working principle: During use, the operator places the air duct above the truss 11, which is located between the first clamping plate 13 and the second clamping plate 14. Then, the long bolt 15 is passed through the first through hole 16 on the first clamping plate 13 and the second clamping plate 14 to clamp and fix the air duct. The second clamping plate 14 cooperates with the first clamping plate 13 to fix the air duct. Relying on the above structure, the second clamping plate 14 can move to adapt to air ducts of different widths, thereby increasing the adaptability range and facilitating the operator's installation.

[0032] During installation, the hanger 12 is mounted on the wall using fasteners. The hanger 12 has external threads and passes through the second through hole 42 on the truss 11. It is then locked in place by a nut 41, thus fixing the truss 11 and adjusting its height to accommodate the duct height and improve its applicability. During installation, as the first clamping plate 13 and the second clamping plate 14 close, their support plate 21 first contacts the duct, and the pressure pushes the support plate 21 and rack 25 to move. The rack 25 meshes with the gear 24, and the movement of the rack 25 causes the gear 24, the rotating shaft 22, and the fixed arm 23 to rotate. The fixed arm 23 is located at... Above the duct, a rotating fixing arm 23 is installed to fix the duct from above, thereby improving the fixing effect and stability of the duct. A support arm 32 is fixedly connected to the first clamping plate 13 and the second clamping plate 14. A guide rod 31 is slidably connected to the support arm 32, thereby improving the stability of the support plate 21. In use, a rubber pad 5 is fixedly connected to the top of the truss 11. The rubber pad 5 is used to pad the bottom of the duct. The elastic structure of the rubber pad 5 can play a certain role in shock absorption. A spring 6 is fixedly connected between the support arm 32 and the support plate 21. The spring 6 is used to drive the support plate 21 to move and reset, thereby facilitating the reset of the support plate 21 and keeping the fixing arm 23 in the open state.
