## Abstract

The present invention is a traffic cone, mainly to utilizes a two-stage formation manufacturing method in which a cone body is injected for combing with a preformed base, wherein the periphery of a through hole having a large dimension and formed at the center of the base is extended with a cone ring part having a preset height, and the upper portion of the cone ring part is formed with a combination part having reduced inner and outer diameter, a preset quantity of convex columnar members are arranged on the inner and the outer surfaces of the combination part with equal intervals, and a fluid passing hole is respectively formed between adjacent convex columnar member, the original material of cone body flows pass the inner and the outer sides of the combination part through the fluid passing holes and combines with the convex columnar member.

## Claims

### Claim 1

An improved structure of traffic cone, mainly to manufacture a base and a cone body of the traffic cone by stages, so the base is firstly preformed, then disposed in a mold for the injection molding of the cone body, the base is able to be formed with various counterweight according to actual needs, and the bottom surface of the base is formed with a positioning slot for positioning the mold, characterized in that:
a through hole having a large dimension is formed at the center of the base, the periphery of the through hole is upwardly extended with a cone ring part having a preset height and taper, the upper portion of the cone ring part is formed with a combination part having reduced inner and outer diameter, a preset quantity of convex columnar members are installed at the circumference of the combination part and arranged with equal intervals, and a fluid passing hole is respectively formed between adjacent convex columnar members, when the cone body is injected for combing with the combination part of the base, the original material of the cone body is allowed to flow pass the inner and the outer sides through the fluid passing holes and obtain a tightly combing relation with the convex columnar members.

### Claim 2 (depends on 1)

The improved structure of traffic cone according to claim 1, wherein the convex columnar members are correspondingly installed at the outer surface, the inner surface or both of the inner and the outer surfaces of the combination part of the base.

### Claim 3 (depends on 1)

The improved structure of traffic cone according to claim 1, wherein the cone ring part of the base is matched with the taper that the cone body is desired to be formed with.

### Claim 4 (depends on 1)

The improved structure of traffic cone according to claim 1, wherein end surfaces of the convex columnar members are matched with the taper that the cone body is desired to be formed with.

### Claim 5 (depends on 1)

The improved structure of traffic cone according to claim 1, wherein the top edge of the combination part of the base is formed as a non-planar state with wave-like configurations.

### Claim 6 (depends on 1)

The improved structure of traffic cone according to claim 1, wherein the base is manufactured and formed by a secondary material having poorer fluidity or recycled material.
