<p>The present invention relates to an improved counterweight structure of traffic cone, which allows the manufacturing of the traffic cone to be provided with lower production cost while the warning function still being kept, a secondary material having lower 5 purchase cost such as a waste or recycled material is adopted for manufacturing an inner base for being combined and enclosed by a traffic cone base thereby saving the product cost of the whole traffic cone; the center of the inner base is formed with a through hole having a large diameter and formed with plural penetrated holes, preset locations on the end surface of the inner base are formed with plural positioning protrusions and further 10 formed with plural abutting protrusions for respectively providing a radial and an axial positioning effect to the inner base disposed in the mold seat thereby preventing from being displaced during injection molding.</p> |
