Preferably, the banking stop perpendicular with described limiting board is also provided with in the movable end one or both sides of described limiting board.
Preferably, described limit position part is two, is symmetricly set in the both sides of described circumference of flange.Described two movable ends are with described bolt for axle, and rotating angular range is 0 ° ~ 15 °.
Preferably, described limit position part is four, is arranged at the fourth class branch place of the circumference of described flange respectively.
Preferably, described spherical protuberances is 1 ~ 3.
Preferably, in described seal ring, steel wire reinforcement circle is provided with.
The beneficial effects of the utility model are:
1. the utility model is provided with limit position part between two flanges, the scope of axial, radial displacement that pipe coupling place occurs and deflection angle can be limited, damages such as stretching is torn, compressive strain of avoiding elastomer connector to produce because of the displacement of over range, add the working life of elastomer connector.
2. the utility model elastomer connector in use can damping noise reduction, can compensate for displacement when pipeline expands with heat and contract with cold, make pipe coupling be subjected to displacement in the safety range preset and deflect, effectively improve the performance of bending rubber joint.
3. banking stop is set at the movable end of limiting board, the deflection angle of limiting board can be constrained in the scope of banking stop permission, prevent limiting board excessive deflection from causing distortion, distortion, damage; Steel wire reinforcement circle is set in seal ring, the sealing of joint can be increased.
