The present invention relates to an elbow assembly structure allowing omnidirectional angular adjustment, which is not limited to installation applications or various installation places but is widely used with respect to a bent place. The elbow assembly structure of the present invention comprises: a body (10) provided in one of "+," "T," "Y," and "L" shapes and has an inner space formed to be hollow; connection holes respectively extended from the body to independent places in four directions, and formed at respective end portions of the body such that inner portions thereof communicate with the hollow body; and multiple connection members (30) provided in a left-right symmetrical fan shape so as to form a curved path, and fixedly coupled with each other in a sequential manner at respective end portions of the connection holes, to vary the curvature range of an area extending from the connection holes. Lead-in projecting portions are extended along a corresponding circumferential surface of one side of the connection member (30) and the end portion of the connection hole, wherein the lead-in projection portion has fitting protrusions arranged at regular intervals so as to enter an adjacent connection member. In addition, coupling grooves are formed in an end portion of the other side of the connection member to be dented inwards, so as to restrain the fitting protrusions and the lead-in projection portions. Therefore, the several connection members (30) can be closely coupled with each other by inter-overlapping of respective fitting protrusions of the lead-in projection portion, and the coupling grooves. |
