Stable plastic wire coil

Abstract

The utility model discloses a stable type plastic wire coil which comprises a wire roller and a blocking piece, one side of the wire roller is provided with an installation hole, an inner cavity of the installation hole is provided with a metal cylinder, one side of the wire roller is provided with a reinforcing hole, an inner cavity of the reinforcing hole is provided with a reinforcing rod, and the right side of the blocking piece is provided with a reinforcing ring. Through cooperation of the metal cylinder, the reinforcing rods and the reinforcing rings, the bearing capacity of the wire roller can be improved through the metal cylinder and the reinforcing rods, the overall structural strength of the wire roller can be improved through the reinforcing rings, the stability of the plastic wire coil is improved, the anti-aging composite layer is designed to be of a three-layer structure, the anti-aging function is achieved, and meanwhile the service life of the plastic wire coil is prolonged. According to the plastic wire coil, the covering layer can be prevented from deforming, the shape of the anti-aging layer is kept, the surface of the plastic wire coil is more resistant to abrasion, higher in impact resistance and good in low-temperature-resistant effect by designing the abrasion-resistant layer, and therefore the effect of high safety is achieved, and the problem that an existing device is low in safety is solved.
