Description

Technical Field

[0001] This application relates to the technical field of air duct installation, and specifically relates to a fixing bracket for a central air-conditioning air duct. Background Art

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air-conditioning systems. The air duct is an important part of the central air-conditioning system, which is used to transport cold and hot air to help adjust the indoor temperature, humidity, and air quality.

[0003] The air duct fixing bracket is a device installed in a building to support and fix the air duct. By using the fixing bracket, it is ensured that the air duct can be correctly installed and positioned, and at the same time, it can also bear the weight of the air duct and the vibration or stress generated by the pressure change in the air duct.

[0004] In order to consider factors such as indoor space, building structure, and equipment location, and optimize the routing and layout of the air duct, a bendable air duct is designed to connect two straight air ducts.

[0005] Due to the diverse layouts of the air ducts, the bending angle of the bendable air duct is adjusted according to the on-site installation. However, the size and position of the conventional fixing bracket are relatively fixed. When facing air ducts with different angles, the bending part of the air duct will be suspended, resulting in poor fixing effect, increasing noise, and also obstructing the air flow in the air duct. Therefore, it is necessary to provide a fixing bracket for a central air-conditioning air duct to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0012] Mounting holes are opened on the first extension plate and the second extension plate, and the mounting holes are adapted to the screw rods;

[0013] The upper ends of the fixed rod, the first vertical rod and the second vertical rod are all installed with fixed plate members, and the fixed plate members are adapted to fix the fixed bracket to the top of the wall.

[0014] Further, the structures of the first chassis and the second chassis are the same. The first chassis has a housing, and an inner shaft is slidably connected inside the housing, and the inner shaft cooperates with the housing.

[0015] Further, a mating hole is penetrated through the inner shaft, a fixing hole is penetrated through the housing, the fixing hole corresponds to the mating hole, and a third bolt is arranged in the fixing hole and the mating hole.

[0016] Further, the first extension plate is flush with the bottom end of the first chassis, the second extension plate is flush with the top end of the second chassis, and the first extension plate and the second extension plate are in contact with each other.

[0017] The beneficial effect of the present application is that: a central air-conditioning air duct fixing bracket provided by the present application adjusts the angle of the fixing bracket to ensure the support and fixation of the bent part of the bent air duct, thereby improving the fixing effect, reducing noise, preventing the air flow in the bent air duct from being blocked, and being able to adapt to bent air ducts with different bending angles.

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] As Figures 1-3 shown, the present application provides a fixed bracket for a central air-conditioning air duct, including a bent air duct 1. The center of the bent air duct 1 is set as an adjustable pipe, so as to facilitate adjusting the bending angle of the bent air duct 1. A fixed bracket 2 is arranged at the lower end of the bent air duct 1, and the fixed bracket 2 is used to fix the bent air duct 1 below the wall top.

[0030] The fixed bracket 2 has a fixed rod 21. The lower end of the fixed rod 21 is rotatably connected to a first bottom frame 24 and a second bottom frame 25. A first vertical rod 23 is arranged at one end of the first bottom frame 24 away from the fixed rod 21, and the first vertical rod 23 and the first bottom frame 24 are fixed by a first bolt 3. A second vertical rod 22 is arranged at one end of the second bottom frame 25 away from the fixed rod 21, and the second vertical rod 22 and the second bottom frame 25 are fixed by a second bolt 4;

[0031] Meanwhile, the upper ends of the fixing rod 21, the first vertical rod 23 and the second vertical rod 22 are all fixedly installed with fixing plate members 5 through the fourth bolts 6. Expansion bolts are provided on the fixing plate members 5. Before installation, corresponding holes are drilled on the top of the wall. Then, the fixing plate members 5 are aligned with the holes and fixed by the expansion bolts.

[0032] In this application, the first bolt 3, the second bolt 4 and the fourth bolt 6 are all prior arts and will not be elaborated here.

[0033] As Figures 2-3 shown, in order to facilitate the installation of the first bottom frame 24 and the second bottom frame 25 to the fixing rod 21 respectively, a screw rod 211 is fixedly installed at the lower end of the fixing rod 21, and a nut 212 is threadedly connected to the screw rod 211;

[0034] Meanwhile, a first extension plate 241 is fixedly installed at one end of the first bottom frame 24 close to the fixing rod 21, a second extension plate 251 is fixedly installed at one end of the second bottom frame 25 close to the fixing rod 21, and mounting holes 242 are formed on both the first extension plate 241 and the second extension plate 251. The mounting holes 242 are adapted to the screw rod 211. During installation, the first extension plate 241 and the second extension plate 251 are sleeved on the screw rod 211, and then the nut 212 is screwed onto the screw rod 211;

[0035] In this application, the first extension plate 241 is flush with the bottom end of the first bottom frame 24, and the second extension plate 251 is flush with the top end of the second bottom frame 25. During installation, the first extension plate 241 and the second extension plate 251 are attached to each other. Therefore, when adjusting the angles of the first bottom frame 24 and the second bottom frame 25, the first extension plate 241 will slide on the second extension plate 251, thus increasing the rotation angles of the first bottom frame 24 and the second bottom frame 25 to adapt to the curved air ducts 1 with different angles.

[0036] It should be noted that the structures of the first bottom frame 24 and the second bottom frame 25 are the same. For the convenience of understanding, the following takes the first bottom frame 24 as an example for elaboration. Specifically:

[0037] In order to adapt to the curved air ducts 1 with different widths, the first bottom frame 24 has a housing 244. An inner shaft 243 is slidably connected inside the housing 244. The inner shaft 243 cooperates with the housing 244. At the same time, multiple groups of mating holes 246 are provided through the inner shaft 243, and fixing holes 245 are formed through the housing 244. The fixing holes 245 correspond to the mating holes 246. In this application, a third bolt 247 is provided in one group of the fixing holes 245 and the mating holes 246 to fix the inner shaft 243 and the housing 244 through the third bolt 247.

[0038] In summary: Before installing and fixing the bent air duct 1, first adjust the bent air duct 1 to an appropriate angle, then remove the third bolt 247, adjust the positions of the outer shell 244 and the inner shaft 243 so that the lengths of the first chassis 24 and the second chassis 25 match the width of the bent air duct 1, and then re-fix the inner shaft 243 to the outer shell 244 through the third bolt 247;

[0039] At this time, first fix the fixing rod 21 on the top of the wall, then put the second extension plate 251 on the screw rod 211, and then fix the second vertical rod 22 on the top of the wall. At this time, place the bent air duct 1 on the second chassis 25 and adjust the angle of the bent air duct 1;

[0040] Finally, put the first extension plate 241 on the screw rod 211 and make it located below the second extension plate 251, and rotate the first chassis 24 along the screw rod 211 so that the angle between the first chassis 24 and the second chassis 25 can stably support the bent air duct 1. Then fix the first vertical rod 23 on the top of the wall and tighten the nut 212 to complete the installation of the bent air duct 1 and the fixing bracket 2;

[0041] Therefore, when facing bent air ducts 1 with different bending angles, by adjusting the angle of the fixing bracket 2, it is ensured that the bent part of the bent air duct 1 is supported and fixed, thereby improving the fixing effect, reducing noise, preventing the air flow in the bent air duct 1 from being blocked, and being able to adapt to bent air ducts 1 with different bending angles.

[0042] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
