An assembled composite air duct comprises: a composite air duct body 1;

[0031] A clamping frame 2, wherein the clamping frame 2 is fixedly mounted on one end of the composite air duct body 1;

[0032] A fixing frame 3, wherein the fixing frame 3 is fixedly mounted on the other end of the composite air duct body 1;

[0033] A movable plate 35, the movable plates 35 are respectively arranged around the fixed frame 3, and the two ends of one side of the movable plate 35 are fixedly installed with a slide bar 32, one end of the slide bar 32 is fixedly installed with a clamping plate 33, and the outer side surface of the slide bar 32 is sleeved with a spring 34;

[0034] A support plate 4 is fixedly installed on the bottom of the composite air duct body 1, and screw rods 41 are fixedly installed on both ends of the top of the support plate 4. The outer side surface of the screw rod 41 is slidably connected with an extension rod 42, and a bearing 45 is fixedly installed on the bottom of the outer side surface of the extension rod 42. A rotating ring 46 is fixedly installed on the outer side surface of the bearing 45, and a threaded sleeve 47 is fixedly installed on the bottom of the inner side surface of the rotating ring 46. The threaded sleeve 47 is threadedly connected to the outer side surface of the screw rod 41.

[0035] The clamping plate 33 is disposed on the inner side of the fixing frame 3 , and the spring 34 is disposed on the top of the clamping portion 32 .

[0036] Limiting grooves 43 are provided on both sides of the screw rod 41, and the inner sides of the two limiting grooves 43 are slidably connected to limiting plates 44. The two limiting plates 44 are respectively fixedly installed on both sides of the bottom of the inner side of the extension rod 42, and a mounting plate 48 is fixedly installed on the top of the extension rod 42.

[0037] The inner thread of the movable plate 35 is connected with a threaded rod 37 , and a handle 36 is fixedly mounted on one end of the threaded rod 37 .

[0038] One end of the threaded rod 37 is disposed on a side surface of the fixing frame 3 , and a sealing gasket 31 is fixedly mounted on one side of the inner side surface of the fixing frame 3 .

[0039] By sliding the limiting plate 44 on the inner side of the limiting groove 43, the extension rod 42 can be limited during use to prevent the extension rod 42 from rotating.

[0040] One end of the outer side surface of the clamping frame 2 is inclined, and one side of the clamping plate 33 is also inclined, so that the clamping frame 2 is conveniently inserted into the inner side surface of the fixed frame 3, so that the clamping plate 33 is moved to one side of the clamping frame 2, so as to install the two composite air duct bodies 1;

[0041] When it is necessary to disassemble the two installed composite air duct bodies 1, the user only needs to rotate the four handles 36 respectively, so that the threaded rod 37 is driven to be threadedly connected inside the movable plate 35, thereby pushing the movable plate 35 away from the fixed frame 3, so that the movable plate 35 drives the clamping plate 33 away from one side of the clamping frame 2 through the sliding rod 32, thereby facilitating the user to disassemble the two spliced ​​composite air duct bodies 1.

[0042] The working principle of the assembled composite air duct provided by the utility model is as follows:

[0043] When in use, when two composite air duct bodies 1 need to be assembled, the user inserts the clamping frame 2 of one composite air duct body 1 into the interior of the fixed frame 3 of the other composite air duct body 1, so that the clamping frame 2 pushes the clamping plate 33. At this time, the sliding rod 32 slides inside the fixed frame 3, and the spring 34 contracts until the clamping plate 33 moves to one side of the clamping frame 2, so that the two composite air duct bodies 1 are installed. When the installation height of the composite air duct body 1 needs to be adjusted, the user can rotate the rotating circle 46 so that the rotating circle 46 drives the threaded sleeve 47 to be threadedly connected to the outer side of the screw rod 41, so that the extension rod 42 slides on the outer side of the screw rod 41, thereby adjusting the height of the composite air duct body 1.

[0044] Compared with the related art, the assembled composite air duct provided by the utility model has the following beneficial effects:

[0045] Through the cooperation of structures such as the snap-fitting frame 2, the fixed frame 3, the sliding rod 32, the snap-fitting plate 33, the spring 34, and the movable plate 35, when in use, the snap-fitting frame 2 is inserted into one side of the inner side surface of the fixed frame 3, and the snap-fitting plate 33 blocks one side of the snap-fitting frame 2, so that the two composite air duct bodies 1 can be installed, which increases the efficiency of installation and facilitates the operation of the user. Through the cooperation of structures such as the screw rod 41, the extension rod 42, the rotating circle 46 and the threaded sleeve 47, the rotating circle 46 drives the threaded sleeve 47 to be threadedly connected to the outer side surface of the screw rod 41, thereby driving the extension rod 42 to slide on the outer side surface of the screw rod 41, so that the user can adjust the installation height of the composite air duct body 1.

[0049] Limit rods 5 are fixedly mounted on both ends of the top of the metal ring 51 , and the limit rods 5 are slidably connected to the inside of the moving plate 35 .

[0050] The working principle of the assembled composite air duct provided by the utility model is as follows:

[0051] After the user rotates the handle 36 to a suitable position, the user can push the metal ring 51 downward, so that the limiting rod 48 rotates inside the movable plate 35, thereby causing the metal ring 51 and the magnetic ring 52 to be magnetically attracted, thereby limiting and fixing the metal ring 51 to prevent the handle 36 from rotating again.

[0052] Compared with the related art, the assembled composite air duct provided by the utility model has the following beneficial effects:
