Description

Technical Field

[0001] The utility model relates to the technical field of composite pipes, in particular to a connecting component for flexible composite pipes. Background Art

[0002] Composite pipes are generally composed of two or more chemical substances. By reasonably selecting materials and strengthening methods, the problems of metal pipe corrosion and poor pressure resistance of plastic pipes are solved, and the performance is more excellent. Therefore, they have been widely used in oil and gas transportation and other aspects. A flexible composite pipe is a pipe fitting for the oil and gas industry made of polymer composite materials, which has certain advantages such as high strength, high pressure resistance, and corrosion resistance.

[0003] The patent with publication number CN221145675U discloses a waterproof and sealed flexible composite pipe joint, which relates to the technical field of pipe connection. It includes an upper fixing plate. A first fixed hinge is fixedly connected to the back of the upper fixing plate. A support rod is rotatably connected inside the first fixed hinge. Two second fixed hinges are fixedly connected to both sides of the outer wall of the support rod. A lower fixing plate is fixedly connected to the back of the second fixed hinge. A second connecting pipe is movably inserted into one side of the top of the lower fixing plate. By the user pulling the handle, the movement of the handle will drive the positioning rod to move, so that the second spring is stretched. By the positioning rod leaving the front of the rotating plate, the rotating plate on the fixing block can be rotated, so that the rotating plate no longer overlaps on the fixing plate, and the fixing plate fixed on the upper fixing plate can be pulled downward forcefully, so that the fixing plate is no longer fixed on the upper fixing plate, and the upper fixing plate can be opened, which is convenient for connecting the first connecting pipe and the second connecting pipe.

[0004] The installation process of the composite pipe joint in the above comparative document is cumbersome, the pipe cannot be quickly locked, and the locking effect is average. It cannot independently perform double locking on the composite pipes on both sides. Therefore, a connecting component for flexible composite pipes is designed here to solve the above problems.
