Elbow of plastic alloy elbow joint device

The utility model relates to an elbow for a plastic alloy bended jointing device, belonging to the cable laying pipe fitting technical field. The utility model is formed by connecting two semi-syphons and is characterized in that: the two sides of the two semi-syphons are respectively provided with a chimb with a connecting through hole; and the two semi-syphons are fixedly connected with two bolts through the connecting through holes. The elbow for a plastic alloy bended jointing device is simple and reasonable in structure, convenient to be used, suitable to connect two pipes when the cable is led out from the ground and connect the turning of two pipes at the same plane; by the design of elbow structure, the utility model can effectively avoid over bending of cables and leads; by using the fission connecting structure of two semi-syphons, the utilization and mounting of the utility model are simpler and more convenient.
