Description

Technical Field

[0001] This utility model relates to the field of building ventilation engineering technology, and more specifically to a duct installation bracket with a self-adjusting shock absorption structure. Background Technology

[0002] During the installation of building ventilation systems, duct mounting brackets are key components for ensuring the stable operation of ducts. Currently, most traditional duct mounting brackets adopt rigid connection structures and lack effective shock absorption and buffering designs. During duct operation, factors such as fan vibration, airflow impact, and changes in ambient temperature can easily cause duct shaking, abnormal noise, and even long-term vibration can lead to problems such as bracket loosening and duct deformation, affecting the normal operation and service life of the ventilation system.

[0003] Meanwhile, existing duct mounting brackets lack flexibility in position adjustment during installation, making it difficult to adapt to the installation needs of ducts of different sizes. Furthermore, after installation, they are ineffective in lateral restraint and longitudinal fixation of the ducts, making them prone to displacement under external disturbances. In addition, traditional brackets have poor corrosion resistance and wear resistance, making them susceptible to damage in humid or highly corrosive environments, increasing maintenance costs and replacement frequency.

[0004] Therefore, developing a duct mounting bracket with self-adjusting shock absorption function, convenient installation and adjustment, firm fixation and long service life is an urgent problem to be solved. Utility Model Content
