Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to a high-performance adjustable sound-absorbing blind. Background Art

[0002] As a common form of curtain, blinds play multiple roles and functions in home life. They not only add a unique aesthetic feeling to the room, but also have functions such as light adjustment, privacy protection, and energy conservation. The roles and functions of blinds in home life will be discussed in detail below.

[0003] A Chinese patent with the publication number of CN211258400U discloses a sound-absorbing blind, which includes a rectangular outer frame, and a plurality of guide plates are rotatably connected in the outer frame along the length direction of the outer frame through a rotating shaft.

[0004] Although the above-mentioned patent makes a plurality of guide plates rotate in the same direction simultaneously as the motor rotates through a transmission member during use, and has the effects of high-efficiency noise reduction and flexible adjustment of the angle of the guide plates, when the guide plates are closed, only the surfaces of each guide plate are in contact. When encountering strong winds, due to the gaps between the guide plates, the wind will drill into the gaps and blow the guide plates to generate noise, resulting in poor sound-absorbing effect of the blind. Therefore, there is an urgent need for a new type of high-performance adjustable sound-absorbing blind to solve these problems. Summary of the Utility Model
