Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, the utility model discloses a steel ring structure, which comprises a rim 1, a spoke 2 and a valve 3.

The rim 1 comprises a rim body 11, a well 12, two bead seats 13 and two rims 14. The well 12 is located in the middle of the rim body 11, bead seats 13 are provided on both sides of the well 12, and the rim 14 is provided on the outside of the bead seats 13.

Specifically, the bead seat 13 is provided with a first bending section 131 and a second bending section 132. A rim hump 133 is provided between the first bending section 131 and the second bending section 132. The slope α of the first bending section 131 is 15 ° ± 1 °. The slope β of the second bending section 132 is 30 ° to 45 °, preferably 45 °. Thereby ensuring smooth transition of bending and facilitating molding and manufacturing.

Specifically, the width of the well 12 is up to 43% of the width of the body of the rim 1. So that the rim 1 body and the spokes 2 can be assembled to a larger threshold offset.

Wherein the outer diameter edge of the spoke 2 is fixedly connected with the inner diameter of the rim groove 12 by welding. The center of the spoke 2 is provided with a middle hole, the outer side of the middle hole is uniformly provided with a plurality of screw holes 21 and wind holes 22 along the circumferential direction, and the screw holes 21 are positioned below the wind holes 22.
