Patent abstract
The utility model discloses an inflatable wheel device for roller skates. The tire has an inflatable structure embedded in the hub, the bearing has a shaft groove, and the return spring is installed in the shaft groove. The shaft rod is embedded in the shaft groove of the bearing in a cross shape and can rotate along the axial direction and the longitudinal direction. The pneumatic tire structure makes the pulley have high elasticity, reduces landing vibration, has good landing performance and fast sliding speed, which can be equivalent to that of roller skates; The cross shaft rod adds two degrees of freedom to the roller skates, especially when the roller skates are inclined to tread sideways, the pedaling angle is increased, the slipping phenomenon is prevented, and the technical actions of ice hockey such as emergency stop and small turn can be realized.
