Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning duct technology, specifically a noise-reducing air conditioning duct. Background Technology
[0002] Air conditioning ducts are channels used by air conditioners to centrally process the return air from the room by utilizing the cooling and heating energy generated by the main unit, such as cooling, heating, humidifying, dehumidifying, and purifying, before sending it back into the room.
[0003] When air enters the duct, the air inside the square tube will generate some noise. The common sound insulation method is to fix the sound insulation board inside the square tube. The sound insulation board needs to be replaced after long-term use, but the sound insulation board is installed inside the duct, which requires the duct to be removed, so it will cause inconvenience to the staff during maintenance. Utility Model Content
[0004] The purpose of this utility model is to provide a soundproof air conditioning duct to solve the problem that when air is introduced into the duct, the air inside the square tube will generate a certain amount of noise. The common sound insulation method is to fix the sound insulation board inside the square tube for sound insulation. The sound insulation board needs to be replaced after long-term use. However, the sound insulation board is installed inside the duct, which requires the duct to be removed, thus causing inconvenience to the staff during maintenance.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a soundproof air conditioning duct, comprising;
[0006] The air duct is provided with a protective plate on the outside of the air duct. A rotating shaft is provided on the outside of the protective plate. The two protective plates are rotatably connected by the rotating shaft. A limit rod is provided on the outside of one of the protective plates. The limit rod passes through the two protective plates and is movably connected to them.
[0007] The bottom of the limiting rod is provided with a sealing plug, which is made of soft silicone and is fitted into the bottom of the limiting rod.
[0008] Preferably, a fixing plate is provided on one side of the protective plate, the fixing plate is fixedly connected to the protective plate, and a sliding groove is provided on the outer side of the fixing plate.
[0009] Preferably, a sound insulation plate is provided on the outside of the chute, and a limiting plate is provided on one side of the sound insulation plate. The limiting plate is fixedly connected to the sound insulation plate, and the outside of the sound insulation plate is in contact with the outside of the air duct.
[0010] Preferably, a slider is provided on the outer side of the limiting plate, the slider is fixedly connected to the limiting plate, and the slider is slidably connected to the fixed plate through a groove.
[0011] Preferably, connecting plates are fixedly provided at both ends of the air duct, and threaded holes are provided on the outer side of the connecting plates.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] When using this device, align the bottom of the slider with the top of the fixed plate and press down on the sound insulation board. This allows the slider to slide into the interior of the fixed plate through the groove, attaching the sound insulation board to the outside of the duct. Then, surround the outside of the duct with the protective plate, sandwiching the sound insulation board between the protective plate and the duct. After enclosure, pass the limiting rod through the connection between the two protective plates and insert the sealing plug into the bottom of the limiting rod, thus limiting the protective plate. The top of the sound insulation board should be flush with the bottom of the top connecting plate of the duct, and the bottom of the sound insulation board should be flush with the top of the bottom connecting plate of the duct. This solves the problem of noise generated by the airflow inside the square tube when air enters the duct. A common sound insulation method is to fix the sound insulation board inside the square tube. However, the sound insulation board needs to be replaced after long-term use. But since the sound insulation board is installed inside the duct, the duct needs to be removed, which causes inconvenience to the staff during maintenance. Attached Figure Description
