Description

Technical Field

[0002] As we all know, air duct is a pipe system used for air delivery and distribution. It is widely used in various industries and is one of the indispensable parts in industrial production. According to the cross-sectional shape, air duct can be divided into circular air duct, rectangular air duct, oblate air duct and other types. Among them, the circular air duct has the smallest resistance, but because the height of the circular air duct is the largest and the production is more complicated, the most commonly used air duct is still the rectangular air duct.

[0003] According to a Chinese patent with the announcement number "CN219712635U", a 90-degree bent air duct connector is disclosed, including an upper air duct and a lower air duct, a first connecting plate is provided on the bottom plate of the upper air duct, a circular connecting groove is provided on the bottom surface of the first connecting plate, a second connecting plate is provided on the top plate of the lower air duct, a circular connecting block is provided on the top surface of the second connecting plate, and the connecting block is deeply connected to the inside of the connecting groove for docking, a sealing ring is provided inside the connecting groove and on the outer side of the connecting block, a plurality of bolt holes are symmetrically provided on the bottom surface of the first connecting plate, and the spacing between the bolt holes is 30°, the upper air duct and the lower air duct can be adjusted at 90°, 120°, 150° and 180°, bolt through holes are provided on the left and right sides of the second connecting plate, and the first connecting plate and the second connecting plate are connected by bolts.
