Further, on the pipe shaft of described public air pipe connector, be provided with the first limit point and reducing; On the pipe shaft of described female air pipe connector, be provided with the first restraining groove.
Further, described the first restraining groove and described the first limit point are corresponding limit structure spare.
Further, on described female air pipe connector, be provided with the anti-lost shrouding of band.
The good effect of the utility model circular duct link is:
(1) utilize male airduct to carry out being connected of circular duct with female airduct, do not re-use flanged surface and be connected with bolt, easy for installation, sealing effect is better.
(2) in the situation that the airduct space is identical, it is maximum that vent area can reach, and duct resistance is reduced, and can select the blower fan of the low one-level of pressure head, therefore can reduce cost and the occupation area of blower fan, can reduce noise simultaneously, reduces local turbulent flow.
(3) manufacturing process is uncomplicated, and I&M is convenient, and is better with the matching relationship of existing railway vehicle air conditioner system, is a kind of air pipe connector that is worthy to be popularized.
