Chamber 12, I 3 outer wall lower end of connector are provided with outwardly extending junction button III 13, and II 4 outer wall lower end of connector is provided with to extension
The junction button IV 14 stretched, junction button III coordinate with junction button I, and junction button IV coordinates with junction button II；Connector I 3, connector II
4 tops are horizontally disposed to have bolt hole 15, connector I 3, connector II 4 to be fixedly connected by the bolt in bolt hole 15.
Further, the fixed lasso I 1, fixed lasso II 2 thickness be 1cm, width 10cm.
The beneficial effects of the utility model：
（1）The utility model is smaller to the air duct diameter change of air duct junction, can avoid in conventional coupling arrangement because even
It connects and reduces air duct diameter, increases the shortcomings that ventilation windage；
（2）Rubber pad and closely knit connection is arranged in air duct junction in the utility model, can reduce air leak rate of air curtain；
（3）The utility model have the characteristics that connection it is closely knit consolidate, be not easy distending, be detachable, can secondary use, the company of reduction
The use cost of connection device.
