Therefore, in order to advance the technology of the industry, prevent the pulley from slipping, better achieve energy conservation, and improve the competitiveness of core technologies, the present application proposes a new implementation scheme that is different from the pulley structure in the prior art.

Closing sheets are respectively provided on both sides of the wheel body. The closing sheets are fixedly connected to the corresponding connecting ribs. A plurality of through openings are opened on one side of the connecting disc.

[0007] Furthermore, a rubber pad is fixedly connected to one side of the closing piece, and the rubber pad is in contact with the connecting rib.

[0012] The beneficial effects of the utility model are:
