Noise-reduction door
The embodiment of the invention provides a noise-reduction door, relates to noise-reduction equipment and solves the problems that the noise-reduction door cannot meet different noise-reduction effects and air duct resistance. The noise-reduction door comprises a T-shaped structural part, two fan-shaped structural parts and a door sheet, wherein the T-shaped structural part and the fan-shaped structural parts are connected with the door sheet through demountable connection structural parts; the T-shaped structural part is positioned at the central axis of the door sheet; and the two fan-shaped structural parts are respectively positioned on the two sides of the T-shaped structural part. Through such manner, different noise-reduction door forms can be obtained by changing the different mounting positions and mounting modes of the fan-shaped structural parts on the door sheet. The noise-reduction door provided by the embodiment of the invention is applied to noise reduction of cabinets.
