Quickly-installed damping air duct finished product support

The utility model discloses a shock-absorbing air duct finished product support capable of being rapidly installed, which belongs to the field of supports and comprises a first C-shaped channel steel, a sleeve connecting sleeve, a second C-shaped channel steel and a dihedral angle type connecting plate. The two ends of the second C-shaped steel channel abut against one side of the bottom end of the first C-shaped steel channel. The outer side of the bottom end of the first C-shaped steel channel is matched with the interior of one side of the dihedral angle type connecting plate. According to the shock-absorbing air duct finished product support capable of being rapidly installed, the mode that the rubber inner core is combined with the springs is adopted, the vibration phenomenon in the using process is reduced, in addition, in the air duct installing process, the installing height can be adjusted in a self-adaptive mode through the rigidity of different springs, and the installing efficiency is improved.
