Provided with through hole, the inner chamber of the through hole has been radially arranged first baffle, and the outer wall vertical of the first baffle sets connecting rod, institute
The inner chamber for stating the first sleeve and second sleeve is mounted on second baffle, and the connecting rod runs through second baffle, and connecting rod
It is fastenedly connected by the first clamp nut with second baffle.
Preferably, first sleeve and the outer wall of second sleeve offer arc groove.
Preferably, the outer wall of the adpting flange is bonded with gasket seal.
Preferably, the second baffle is strip baffle plate, and is radially arranged in the inner chamber of the first sleeve.
Preferably, the quantity of the strip groove be no less than three, it is and circumferentially distributed in the outer wall of connection ring.
The utility model proposes a kind of ventilating duct connect sealing structure, beneficial effect is：By set connection ring and
Piston, ventilating duct is set in connection ring outer wall when connecting ventilating duct, rotates the first clamp nut, piston and connection ring inwall
Contact and extrude connection ring, realize the sealing of ventilating duct and connection ring, while whole connecting elements is located at sleeve inner, the company of avoiding
Connecing framework is influenceed and is got rusty by mine internal environment, further improves the sealing property of the sealing structure, while need not
Ventilating duct is locked using clip, it is convenient to be installed with operator.
