PURPOSE: A pipe connector for a banner is provided to simplify an assembly process by fixing a pillar with nuts without additional components. CONSTITUTION: A lower pipe connector is fitted to the center of a support. A lower pillar is fixed to the support by the lower pipe connector. An upper pillar is withdrawn from the lower pillar. An upper pipe connector fixes the upper pillar. A tapered screw(3b,6b) of a connector body(3a,6a) is combined with a nut(11) to fix the upper pillar. A wedge(13) is formed in the tapered screw with a U type cut unit(12). A screw groove(13a) is formed on the upper side of the wedge to correspond to a screw thread(11a) of the nut. A ground surface is formed on the sides of the upper and lower pillars. |
