End is equipped with connecting hole, and the center of the connecting seat is equipped with link block, and the link block is equipped with left hoop body, right hoop body, the left side
Hoop body, right hoop body inner end with link block be rotatablely connected, the left hoop body, right hoop body outer end be equipped with engaging lug, it is described
Engaging lug be equipped with through-hole, left hoop body, right hoop body outer end connection after form annulus；The inner arc of the left hoop body, right hoop body
Face is equipped with arc groove, and arc air bag is equipped in the arc groove, is connected between the inner end of arc air bag by flexible joint
It connects, the air flue of two arc air bags of connection is equipped in flexible joint, the outside of left hoop body is equipped with air inflation nozzle, the air inflation nozzle
Inner end is connected with arc air bag.Connecting seat is connect with wall, and the outer end of left hoop body, right hoop body is unfolded, and exhaust duct is caught in left hoop
Then position between body, right hoop body is connected the outer end of left hoop body, right hoop body by bolt, nut, at this time exhaust duct and a left side
There are gaps between annulus after hoop body, the connection of right hoop body, are inflated finally by air inflation nozzle into arc air bag, arc air bag fills
Exhaust duct is held tightly, realizes positioning by expansion after gas；After arc airbag aeration automatically by gap filling, compensation, even if in annulus
The center bias of the heart and exhaust duct does not also influence, and greatly reduces positioning accuracy request；And arc air bag has well
Damping, sucking action, exhaust duct is collided, internal gas flow by when Gas Vibration be not easy to occur noise.
Preferably, the two bottom sides of the arc groove are equipped with arc-shaped slot, the extrados both sides of the arc air bag are set
There is the arc strip coordinated with arc-shaped slot.Arc-shaped slot is used for the positioning of arc air bag.
Preferably, the intrados of the arc air bag is equipped with several spherical boss.It is spherical convex after arc airbag aeration
Platform is contacted with air draft pipe surface, increases contact friction force, while burr that can also prevent air draft pipe surface etc. punctures arc air bag,
It plays a protective role to arc air bag.
Preferably, the outside of the connecting seat is equipped with sliding slot, sliding block is equipped in the sliding slot, the side of sliding slot is equipped with
Locking bolt, the link block are fixedly connected with a slide block.Locking bolt is first unclamped, exhaust duct is packed into and then to arc gas
Capsule is inflated, and the rear slider of inflation is moved along sliding slot to be automatically adjusted to equilbrium position, then tighten locking bolt.
Therefore, the utility model has low installation accuracy requirement, exhaust duct positioning stablity, the advantageous effect for being capable of noise abatement.
