[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 protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4 As shown, a quick-installation smoke exhaust duct includes: a duct channel 1 and two sets of mounting seats 2, the two sets of mounting seats 2 being respectively disposed on both sides of the duct channel 1; a quick-installation mechanism 3, the quick-installation mechanism 3 being installed on the surface of the duct channel 1, the surface of the quick-installation mechanism 3 being connected to the lower end of the adjacent mounting seat 2; wherein, the quick-installation mechanism 3 includes a limiting component 31 installed on the upper end of the duct channel 1, and a positioning component 32 being disposed on the surface of the duct channel 1, the positioning component 32 being connected to the lower end of the adjacent mounting seat 2;

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the limiting component 31 includes two sets of fixed tubes 311 fixedly connected to the upper end of the air duct channel 1. One side of the fixed tubes 311 are evenly distributed in a straight line along the upper end of the air duct channel 1. Two rotating shafts 312 are rotatably connected to the inner wall of the fixed tubes 311. Multiple metal strips 313 are fixedly connected to the surface of the rotating shafts 312. The other end of the rotating shaft 312 passes through the inner wall of the adjacent fixed tube 311. One end of the rotating shaft 312 is fixedly connected to the end of the adjacent rotating shaft 312. Multiple metal strips 313 are evenly distributed in a straight line along the surface of the rotating shaft 312. The surfaces of two metal strips 313 are in contact with the surface of the positioning component 32.

[0024] When using the device, the duct channel 1 is placed on the upper end of the support frame 322, and after the duct channel 1 is pushed to the installation position, the rotating shaft 312 is manually rotated. At this time, the metal strip 313 is moved to fit against the surface facing the connecting hanger 321. The metal strip 313 is made of deformable strip metal. The metal strip 313, which is not in contact with the connecting hanger 321, limits the movement of the duct channel 1, thereby improving the convenience of installation.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the positioning component 32 includes two connecting hangers 321 fixedly connected to the lower end of the mounting base 2. A supporting crossbeam 322 is fixedly connected to the lower end of the connecting hanger 321. The upper end of the supporting crossbeam 322 contacts the lower end of the air duct channel 1. A positioning lock 323 is sleeved on the surface of the connecting hanger 321 near the air duct channel 1. A connecting plate 325 is fixedly connected to the side of one side of the positioning lock 323. A hook 326 is hinged to the upper end of the connecting plate 325. A spring piece 327 is fixedly connected to the surface of the hook 326. The other end of the spring piece 327 is fixedly connected to the surface of the connecting plate 325. A protruding buckle 324 is embedded in the inner side of the connecting hanger 321. One end of the protruding buckle 324 extends through the connecting hanger 321.

[0026] The bend of the hook 326 engages with the surface of the protrusion 324. The spring 327 drives the positioning lock 323 to be positioned on the surface of the connecting hanger 321 near the mounting base 2. During use, after the air duct 1 moves the limiting component 31 to the installation position, the hook 326 is manually moved to separate the bend of the hook 326 from the upper end of the protrusion 324. At this time, multiple positioning locks 323 slide down along the surface of the connecting hanger 321 under the action of gravity. At this time, the two metal strips 313 are in contact with the surfaces of the two connecting hangers 321. During the downward movement, the positioning lock 323 will wrap the surface of the metal strip 313 near the end inside the positioning lock 323. The end of the metal strip 313 will extend into the interior of the positioning lock 323. At this time, the gap between the positioning lock 323 and the connecting hanger 321 is inserted by the metal strip 313 to form a positioning effect, which improves the convenience of installation.

[0027] In use, the bend of the hook 326 engages with the surface of the protrusion 324. The spring 327 drives the positioning lock 323 to be positioned on the surface of the connecting hanger 321 near the mounting base 2. The duct channel 1 is placed on the upper end of the supporting crossbeam 322. After pushing the duct channel 1 to the installation position, the rotating shaft 312 is manually rotated to move the metal strip 313 to the surface of the connecting hanger 321. The metal strip 313, which is not in contact with the connecting hanger 321, limits the movement of the duct channel 1. When the upper end of the hook 326 is separated from the buckle 324, multiple positioning latches 323 slide downward along the surface of the connecting hanger 321 under the action of gravity. The two metal strips 313 are in contact with the surfaces of the two connecting hangers 321. During the downward movement, the positioning latches 323 will wrap the surface of the metal strips 313 near the end inside the positioning latches 323. The gap between the positioning latches 323 and the connecting hangers 321 is filled by the metal strips 313 to form a positioning effect, which improves the convenience of installation.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment are also appropriately combined to form other embodiments understood by those skilled in the art.
