The present invention relates to an assembling structure for an elbow capable of regulating the angle at all directions, which is not limited to installation usages or spaces and can be widely used in bending places. The assembling structure for an elbow comprises a body (10) which is included in one shape among "'+," "T," "Y," and "L" and has a hollow inner space; connecting holes (20) which are extended to independent places respectively toward all directions from the body, and where the hollow body communicates with and the inside thereof; and multiple connecting members (30) which are included a symmetric fan shape in order to form a path on a curved surface, and change the relevant curvature range to an area extended from the connecting holes by fixating and connecting the connecting holes by making each end of the connecting holes consecutively neighbor. The connecting member (30) is made of metal or nonferrous metal, and extends and forms an inserting protrusion unit (35) at one side thereof, which is included in a spiral concavo-convex shape in order to enter and be included inside the connecting hole (20) or an adjacent connecting member. One or more fixing pieces (37, 21) are formed to protrude from the other side of the connecting member and the inside of the connecting hole. A concave groove is placed at the relevant end where connecting members are overlapped, and a sealing member formed of an elastic material and a coupling ring is inserted into the concave groove. The inserting protrusion unit (35) includes a straight tooth form protrusion (36) which is formed of continuous concave and convex shapes on the entering path of the fixing piece in order to confine both ends of the head (37a) of the fixing piece. Therefore, multiple connecting members can be closed connect with one another through mutual confinement between each inserting protrusion unit and fixing piece. |
