CONNECTING STRUCTURE FOR PIPELINE

摘要

The present invention relates to a connecting structure capable of improving stability in a pipeline, which comprises: a main pipe unit; a box unit which extends from one longitudinal section of the main pipe, wherein the size of the cross section of an inner circumferential surface increases as the cross section gets away from the main pipe unit, a curve is formed in the longitudinal direction of the main pipe part, and a female screw part is formed on the inner circumferential surface; a connecting pipe which is connected to the main pipe unit; and a fin unit which extends from the one longitudinal section of the main pipe and can be inserted into the box unit, such that a male screw unit can be formed on the outer circumferential surface so as to engage in correspondence with the female screw part.
