Abstract
Description
Technical Field
[0001] This utility model belongs to the field of road cone technology, and in particular relates to an upper connecting device for the main body of a road cone. Background Technology
[0002] In order to prevent the recurrence of dangers and traffic accidents during road construction and when traffic accidents occur, workers will place traffic cones at a distance behind the construction site or the accident site to serve as warnings and guides. At the same time, traffic cones are easy to store and transport, and can quickly and effectively form temporary warning areas, thereby greatly increasing the efficiency of road construction and traffic accident handling, and protecting the lives of personnel on site. Therefore, traffic cones have become an indispensable and important early warning equipment in road traffic control.
[0003] Traditional traffic cones are generally passive reflective, using a reflective layer on their outer surface to reflect vehicle headlights and warn drivers of obstacles ahead. This reflective layer is typically made by coating fluorescent powder onto a plastic film to form a reflective layer, which is then placed on the outer surface of the traffic cone. However, because traffic cones are exposed to the elements for extended periods, long-term exposure to wind, rain, and sun can easily cause the reflective layer to separate from the cone, reducing or eliminating its warning function. In addition, some traffic cones have smooth surfaces, making them difficult to lift and move. Summary of the Invention
[0004] The purpose of this invention is to provide a connecting device for the upper part of a traffic cone that facilitates lifting and effectively fixes a plastic film coated with fluorescent powder.
[0005] The purpose of this utility model is to solve the following problem:
[0006] An upper connecting device for a traffic cone body includes a tubular body extending downward along the inner edge of a horizontally placed circular ring plate. The inner wall of the tubular body has a vertical groove. Two or more downwardly extending extension plates are spaced apart on the lower end face of the tubular body. The lower end of each extension plate has an outwardly flanged claw forming a snap-fit. An annular outer shell extending downward along the outer edge of the circular ring plate has a radius that gradually increases from top to bottom. The outer wall of the outer shell has annular grooves spaced vertically, and the inner wall of the outer shell has annular protrusions spaced vertically.
[0007] As a further optimization of the above technical solution, the annular groove is a wavy groove, which is arranged circumferentially around the outer wall of the outer shell.
[0008] As a further optimization of the above technical solution, the annular groove is a triangular groove.
[0009] As a further optimization of the above technical solution, the corners of the triangular groove are rounded.
[0010] As a further optimization of the above technical solution, the cross-section of the annular protrusion is triangular or semi-circular.
[0011] As a further optimization of the above technical solution, the upper connecting section of the traffic cone is an integral structure injection molded from plastic material.
[0012] As a further optimization of the above technical solution, the thickness of the outer flange gradually decreases from the inside to the outside.
[0013] As a further optimization of the above technical solution, the height of the lower wall of the outward flange from the inside to the outside gradually increases from the lower end face.
[0014] As a further optimization of the above technical solution, the groove is a rectangular groove.
[0015] As a further optimization of the above technical solution, the wall thickness of the tubular body and the wall thickness of the groove are of equal thickness.
[0016] The advantages of this invention compared to the prior art are:
[0017] 1. This utility model has annular protrusions spaced vertically on the inner wall of the outer shell. After docking with the lower body of the traffic cone, the plastic film coated with fluorescent powder can be effectively fixed on the traffic cone, and the plastic film is not easy to fall off the traffic cone body.
[0018] 2. This utility model has annular grooves spaced vertically on the outer wall of the outer shell to facilitate lifting the traffic cone when moving it.
[0019] 3. The present invention has a snap-fit claw on the lower end face of the tubular body inside the outer shell, which facilitates snap-fit docking with the lower main body of the traffic cone, making connection and assembly convenient.
[0020] 4. This utility model has a simple structure, is easy to lift and handle, and effectively fixes the plastic film, making it suitable for the upper connection structure of traffic cones. Attached Figure Description
