The main hinge plate component 3 and the auxiliary hinge plate component 4 can be made of GB/T12777-2019 products.
Example two.
The structure of this embodiment is substantially the same as that of the first embodiment, and the main difference is that: in the embodiment, the main hinge plate assembly and the auxiliary hinge plate assembly are not used, but two groups of hinge assemblies are respectively arranged on the two end connecting pipes and are arranged by being staggered by 90 degrees. Meanwhile, the hinge assembly is connected with the universal ring through a pin shaft, so that corresponding angular displacement compensation is realized, and internal pressure thrust generated by the corrugated pipe is borne. The hinge assembly and gimbal ring may be selected from the gimbal hinge type expansion joints of GB/T12777.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
