Description

Technical Field

[0001] This utility model belongs to the field of ventilation duct technology, specifically relating to an anti-vibration structure for building ventilation ducts. Background Technology

[0002] With the rapid development of modern buildings, industrial facilities and rail transit, ventilation duct systems, as the core carriers of air circulation and environmental regulation, are receiving increasing attention for their safety and stability.

[0003] At the connection point of the ventilation duct, when air is flowing inside the ventilation duct, the eddy current generated by the air will cause the ventilation duct to vibrate. At the connection point between two ventilation ducts, the vibration will create a certain gap or a gap between the connection point and the sealing ring, causing gas to be discharged through the gap.
