During appearance, the concaveconvex structure of neighbouring bonds is mutually inserted to form assembling, so as to improve connection sealing.
Preferably, the width of anchor ear is at least the distance between outer trough of corrugated tube end of two connections and sealing ring
Width sum.
Preferably, the side of anchor ear is provided with flanging, flanging is towards the direction side bending of the anchor ear arc center of circle.Pass through folding
Side can carry out spacing to sealing ring.
Preferably, the middle part of anchor ear is provided with the polyurethane inlet of radial direction insertion.
The beneficial effects of the utility model are：Sealing ring is monolithic construction, it is ensured that attachment structure is in a circumferential direction
Sealing, it is to avoid the seepage after connection in the axial direction；Three-stage anchor ear is coordinated to hold sealing ring, and filled polyurethane tightly, so that real
Existing bellows connection and sealing, good airproof performance, sealing ring is separated for complete circle and with anchor ear, with the deformation energy of bellows
Power is not restricted by anchor ear.
