发明名称 Traffic cone

The frustum-conical body has a hole in an upper end surface for a signal lamp, and a partial portion of its circumferential wall is thicker than another portion to form a gap between every two traffic cones stacked-up for easily taken off. The frustum-conical body has its bottom formed with a flange consisting of an upper and a lower annular wall and short ribs formed between the upper and the lower annular wall. The upper and the lower annular wall respectively have connect holes facing one another. The upper annular wall has an auxiliary material filling holes beside every connect hole and the lower annular wall has projecting arms. The base has a center hole to fit around the flange of the frustum-conical body to be combined with the same body as integral.
