Compared with prior art, the inner surface of the outer tube of the flexible duct transition joint extends out from inside to outside, outer tube
Inner surface be evenly arranged with multiple annular snap-latch surfaces that section is zigzag distribution, the outer surface of the sleeve end of inner core tube is uniform
Multiple annular snap-latch surfaces that section is zigzag distribution are provided with, thus greatly strengthen the sealing of flexible duct transition joint
Property, this certain caliber for changing inner core tube makes the caliber of inner core tube different, so interior for convenience to expand, it is necessary to which internal diameter tube is divided
Engaged for two sections by transition joint, while the setting of the splined section of transition joint and internal diameter tube joint can limit inner core
Pipe rotates, and prevents from rotating between two sections of inner core tubes and causes airway tube torsional deformation, while connector and connector internal ventilation passage
Setting leaking medium is in circulation status, flow to the discharge of the flexible duct transition joint other end, and the structure setting makes
Exhaust passage will not distort or extrude because of pipeline and block deformation, and leaking medium will not be accumulated, and emission effect is good.
