a carbon fiber corrugated pipe comprises a carbon fiber layer and a PVC (polyvinyl chloride) line pipe;

the end face of the PVC spool is uniformly provided with a plurality of convex rings, the carbon fiber layer is completely coated on the surface of the PVC spool, and the carbon fiber layer is coated to the convex rings to be bulged to be matched with the shape of the PVC spool for molding.

Preferably, two ends of the carbon fiber corrugated pipe are respectively provided with a joint part and a joint part, the head end of the PVC pipe of the joint part is enlarged for the joint part to connect, and the joint part is connected with the joint part to connect the two carbon fiber corrugated pipes together.

Preferably, the connector part and the joint part are both provided with threads, the threads of the connector part are arranged on the inner wall of the PVC conduit, and the threads of the joint part are arranged on the surface end face of the carbon fiber layer.

Preferably, the PVC conduit is of unitary construction.

Preferably, the PVC conduit is locally bent.

Compared with the background technology, the utility model has the beneficial effects that:

adopt fashioned carbon fiber bellows of this scheme, can regard as the shaping substrate to use with the PVC pipe, do not influence threading guard action, cladding one deck carbon fiber layer on the PVC spool simultaneously, utilize carbon fiber's intensity high, corrosion-resistant characteristics, solved the easy corruption of traditional metal, plastics bellows, the easy damaged problem of pressurized has improved life. The scheme has the advantages of simple structure, compact connection, reasonable design and the like, so that the scheme is a product with both technical and economical properties.
