Problems solved by technology

In the drifting movement, in order to enhance the wear resistance of the products currently on the market, the hardness of the roller is relatively high. During the sliding process, the acceleration is not fast enough and the comfort is poor; Ground force; the most important thing in sports is to accelerate the start and stop quickly, which requires the skate wheel to have high elasticity and deformation grip. At present, the single-layer structure wheel on the market cannot meet such requirements; the elasticity of the current...

Embodiment Construction

[0013] specific implementation plan

[0014] refer to Figure 1-2 , a double-layer speed pulley, which includes a core 1, an inner tank 2, and an outer tank 5, the core 1 is in a circular shape, and a circle of waist-shaped holes 4 is added to the edge of the core 1, and the center of the core 1 is designed with a shaft hole 3 for For installation, an inner liner 2 is designed on the outer side of the inner liner 1, and the inner liner 2 is in the shape of a ring, and the inner liner 2 is fixedly connected with the outer edge of the inner liner 1 through injection molding, and the outer liner 5 is located on the outer side of the inner liner 2 in a ring shape, and the outer liner 5 is in the shape of a ring. The liner 5 wraps the inner liner 2, and the inner side of the outer liner 5 wraps the waist-shaped hole 4 on the edge of the inner liner 1 by injection molding, and the outer liner 5 is fixedly connected with the inner liner 2 and the inner liner 1.

Abstract

The invention relates to a double-layered speed skating wheel. The double-layered speed skating wheel comprises an inner core, an inner container and an outer container, wherein the inner core is in around shape; a circle of kidney-shaped holes are additionally formed in the edge of the inner core; an axial hole for mounting is designed in the center of the inner core; the inner container is designed on the outer side of the inner core; the inner container is in a circular ring shape and is fixedly connected with the outer side edge of the inner core through injection molding; the outer container is positioned on the outer side of the inner container and is in a circular ring shape; the outer container covers the inner container; the inner side of the outer container covers the kidney-shaped holes formed in the edge of the inner core through injection molding; the outer container, the inner container and the inner core are fixedly connected with each other. The double-layered speed skating wheel has the advantages that a double-layered structure is adopted; due to the kidney-shaped holes formed in the edge of the speed skating wheel, air exhaustion is facilitated; a circle of inner container of the speed skating wheel is prepared from a soft polyurethane material through injection molding, and the hardness reaches Shore hardness A-level of 65A, so that when wheels incline forturning and steering, the double-layered speed skating wheel has good road holding property, no loss of speed is ensured, and the double-layered speed skating wheel is controlled more easily.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a double-layer speed pulley. Background technique [0002] In the past, the technology of speed pulleys has a single-layer structure, and there are certain defects in targeted applications. In the drifting movement, in order to enhance the wear resistance of the products currently on the market, the hardness of the roller is relatively high. During the sliding process, the acceleration is not fast enough and the comfort is poor; Ground force; the most important thing in sports is to accelerate the start and stop quickly, which requires the skate wheel to have high elasticity and deformation grip. At present, the single-layer structure wheel on the market cannot meet such requirements; the elasticity of the current speed skating products is not The best, so the acceleration is not enough. More importantly, when passing the curve in the speed skating competition, in order not to fa...
