The present invention relates to a flexible joint coupling structure formed into a unit coupling body composed of a packing member, an insulating member, a middle connector, and a coupling connector and used as a connecting pipe to connect a flexible pipe formed into a different shape with different size and having a low out-of-roundness with other pipes. Especially, in the past, a middle connector and a coupling connector for a heavy and large normal pipe that are not proper to a flexible pipe having a structure reinforced by furrows and formed into a thin pipe of a thin plate material at all are applied to the flexible pipe, thus a flexible joint is excessively heavy and large. To solve this, a flexible joint is formed by using the middle connector and the coupling connector formed of a thin pipe and having a specialized shape proper to the flexible pipe, thus the stronger and more efficient structure proper to the purpose is formed. The purpose of the present invention is to achieve the flexible joint capable of remarkably reducing manufacturing costs and providing an excellent construction quality by replacing the coupler into the cheap and economic one. |
