Wheel core capable of preventing tread from peeling off and roller skate

Abstract

The invention discloses a wheel core capable of preventing a tread from peeling off and a roller skate. The wheel core comprises a body and a fastening structure for preventing a high polymer materialfrom peeling off due to lateral stress. The body comprises spokes, a hub and a rim, the spokes are connected with the hub and the rim, and the fastening structure is arranged on the rim in the circumferential direction of the body. The fastening structure is of a kidney-shaped hole structure with at least two layers. The roller skate comprises a wheel carrier and the wheel core capable of preventing a tread from peeling off, a high polymer material is poured outside a wheel rim to form a tread, the thickness of the wheel core is 15-21mm, and a body is rotationally connected with the wheel carrier. Compared with the prior art, the thin wheel core has the advantages that the weight is reduced, the roller skate is more competitive in a match, the material cost is reduced, and resources are saved; due to the existence of the double-layer kidney-shaped holes, when the high polymer material is poured outside the rim, the combination area of the wheel core and the high polymer material is greatly increased, the anti-peeling performance is improved, and the roller skating wheel is more stable when the included angle between the roller skating wheel and the ground is changed.

Description

Technical field [0001] The invention relates to the field of sporting goods, in particular to a wheel core and roller skates with anti-tread peeling. Background technique [0002] In daily life, roller skating is a great means of transportation; in the field of sports, there are many competitions. In each event, especially in speed skating, special attention is paid to the performance of roller skates; when it comes to roller skates, you must It is necessary to mention the wheels of roller skates. For many years, the thickness of the inline skate wheels has always been maintained at 24mm, which has led to the inline skates not being able to be more lightweight, resulting in always being restricted by their weight in the competition. At the same time, the material cost is high and wasteful, and it is more cumbersome to dispose of scrapped wheels as garbage. [0003] After the wheel is thinned, it is difficult to meet the requirements of product testing, especially the problem of ea...

Problems solved by technology

[0002] In daily life, roller skating is a great means of transportation; in the field of sports, there are many kinds of events. In each event, especially in speed skating events, the performance of roller skates is particularly important; when it comes to roller skates, it must be When it comes to the wheels of roller skates, the thickness of inline skate wheels has been kept at 24mm for many years, which leads to the inline skates not being able to achieve better weight reduction, resulting in always being restricted by their weight during competitions. At the same time, the cost of materials is high and wasteful, and it is more cumbersome to dispose of scrapped wheels as garbage

[0003] After the wheel is thinned, it is difficult to meet the requirements of product testing, especially the problem that the tread and the wheel core are easy to separate
