DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The air duct of the air conditioner is a passage used by the air conditioner to utilize the cold and heat generated by the main unit to centrally process the return air (or a mixture of return air and fresh air) from the room, such as cooling, heating, humidifying, dehumidifying, purifying, etc., and then send it into the room. After the air duct of the central air conditioner is damaged during use, it needs to be disassembled for maintenance. After the air duct is disassembled, because the air duct is generally high, the maintenance personnel need to support the air duct to prevent it from falling. However, manually supporting the air duct is not only labor-intensive but also easy to fall. Therefore, it is necessary to provide a new air duct maintenance bracket for central air conditioners to solve the above technical problems. The present application drives the threaded rod to rotate by rotating the rotating disk, and the rotation of the threaded rod drives the ring to slide up and down along the connecting column, thereby driving the second connecting arm to rotate, and the rotation of the connecting arm drives the first connecting arm to rotate, so as to facilitate its storage, and the height of the top plate can be adjusted by opening and closing the first connecting arm.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a duct maintenance bracket for a central air conditioner, comprising a top plate 1, a supporting mechanism 2, a connecting mechanism 3 and an adjusting mechanism 4 are installed at the bottom of the top plate 1, the supporting mechanism 2 comprises a first connecting arm 201, a plurality of first connecting arms 201 are provided and are rotatably connected to the outer wall of the top plate 1, the connecting mechanism 3 comprises a fixing frame 301, the fixing frame 301 is fixedly connected to the middle of the bottom of the top plate 1, connecting columns 304 are respectively fixedly connected at both ends of the bottom of the inner side of the fixing frame 301, a matching circular ring 303 is slidably connected to the outside of the connecting column 304, and second connecting arms 305 are rotatably connected to the opposite sides of the outer wall of the circular ring 303, and the second connecting arm 305 is rotatably connected to the corresponding inner side of the first connecting arm 201.

[0022] The adjusting mechanism 4 comprises a connecting block 401 , which is fixedly connected between the two rings 303 , and a threaded rod 402 is threadedly connected to the middle of the connecting block 401 .

[0023] The bottom end of the threaded rod 402 passes through the bottom end of the fixed frame 301 and is fixedly connected to a rotating disk. The middle of the inner top of the fixed frame 301 is fixedly connected to a bearing. The inner wall of the inner ring of the bearing is fixed to the outer wall of the top of the threaded rod 402.

[0024] Sliding holes 302 are respectively provided at both ends of opposite sides of the outer wall of the fixing frame 301 , and the sliding holes 302 and the second connecting arms 305 are matched.
