[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figure 1 and Figure 4 As shown, an air conditioning static pressure box with an air leakage prevention structure includes a box body 1 and a fastening assembly 4. The lower end of the box body 1 is connected to an installation port 2, and an air outlet 3 is snapped onto the outside of the installation port 2. The air outlet 3 is snapped onto the outside of the installation port 2. The front end of the surface of the box body 1 is connected to a connection port 5 by screws. The connection port 5 connects the box body 1 to the pipe. The inside of the box body 1 is provided with a static pressure chamber 6. The box body 1 and the installation port 2 are fixedly connected, and the box body 1 and the static pressure chamber 6 are an integrated structure.

[0024] like Figure 2 As shown, a fastening assembly 4 for increasing connection tightness and preventing air leakage is installed outside the air vent 3. The fastening assembly 4 includes a side baffle 401, a movable hole 402, a control rod 403, a fastening plate 404, and a spring 405. The side baffle 401 has a movable hole 402 on its surface, which provides adjustment space for the control rod 403. The side baffle 401 is U-shaped and serves as an external limiter outside the air vent 3. The side baffle 401 and the fastening plate 404 are fixedly connected. The control rod 403 is installed inside the movable hole 402. Pulling the spring 405 with 403 extends the fastening plate 404, which moves closer to the side baffle 401 to facilitate the installation of the air vent 3. After releasing the control rod 403, the end of the control rod 403 is connected to the fastening plate 404, and the inner side of the control rod 403 is equipped with a spring 405. The spring 405 and the side baffle 401 are fixedly connected, and three springs 405 are linearly distributed about the side baffle 401. The rebound force of the spring 405 causes the fastening plate 404 to reinforce and limit the air vent 3 from the outside, increasing the connection firmness and sealing, and preventing air leakage after the air vent 3 is installed.

[0025] like Figure 3As shown, an adjustment component 7 for wind speed adjustment is provided on the inner side of the air outlet 3, and two sets of adjustment components 7 are provided. The adjustment component 7 includes a hydraulic rod 701 and an adjustment plate 702, and the output end of the hydraulic rod 701 is provided with the adjustment plate 702. The output end of the hydraulic rod 701 and the surface of the adjustment plate 702 are rotatably connected. The adjustment plate 702 and the air outlet 3 are rotatably connected. The hydraulic rod 701 controls the rotation adjustment of the adjustment plate 702 in the inner wall of the air outlet 3 by telescopic control, thereby adjusting the ventilation diameter of the air outlet 3, thereby changing the ventilation volume and ventilation velocity of the air outlet 3. The adjustment plate 702 and the inner wall of the air outlet 3 form an acute angle.

[0026] In summary, this air conditioning static pressure box with an air leakage-proof structure is first based on... Figures 1-4 The structure shown first connects the connection port 5 to the air conditioning duct, then snaps the air vent 3 onto the outside of the installation port 2. During installation, the side baffle 401 acts as an external limiter outside the air vent 3. Then, pulling the control rod 403 and moving it outward causes the spring 405 to extend and the fastening plate 404 to move outward. After the air vent 3 is installed, the control rod 403 is released. The rebound force of the spring 405 causes the fastening plate 404 to reinforce and limit the air vent 3 from the outside, increasing the connection firmness and sealing, and preventing air leakage after the air vent 3 is installed. When adjusting the ventilation flow, because the output end of the hydraulic rod 701 is rotatably connected to the surface of the adjusting plate 702, the hydraulic rod 701 can be controlled to extend and retract, causing the adjusting plate 702 to rotate and adjust within the inner wall of the air vent 3. The adjustment of the distance between the two sets of adjusting plates 702 can adjust the ventilation diameter of the air vent 3, thereby changing the ventilation volume and ventilation speed of the air vent 3.
