[0007] A wheel with a hollow structure includes a rim. A tire is arranged on the outer wall of the rim, and a bearing is arranged on the inner wall of the rim. The rim is composed of a first mating ring and a second mating ring. One end of the first mating ring close to the second mating ring is fixedly connected with bolts at equal intervals. Arc-shaped holes are opened at equal intervals on the front end face of the second mating ring. The front ends of the bolts penetrate through the arc-shaped holes and are threadedly connected with nuts, and the right ends of the nuts are abutted against the front end of the second mating ring.

[0008] Preferably: A bearing is fixedly connected to the inner wall of the first mating ring, and mounting frames are fixedly connected to the inner wall of the bearing at equal intervals.

[0009] Preferably: Limiting grooves are opened at equal intervals on one end face of the first mating ring close to the second mating ring, and clamping grooves are arranged inside the limiting grooves.

[0010] Preferably, one end of the second mating ring close to the first mating ring is fixedly connected with connecting blocks at equal intervals. The connecting blocks are located inside the card slots. One end of the connecting block away from the second mating ring is fixedly connected with a clamping block, and the clamping block is located inside the card slot and is engaged with it.

[0011] Preferably, a hand wheel is fixedly connected to the front end of the second mating ring through a connecting rod.

[0012] Preferably, the tire is designed as a solid structure, and hollow holes are arranged at equal intervals on the front end face of the tire.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model adopts an innovative tire installation method. Through the coordinated action of the first mating ring and the second mating ring, the tire installation process is simplified, and the step of using expansion equipment to expand the inner diameter of the tire in the traditional installation process is omitted, thereby reducing the equipment investment and maintenance costs of the enterprise and effectively solving the problem of cost control.

[0015] 2. Through the coordinated action of the carefully designed limiting grooves, card slots, bolts, nuts, arc-shaped holes and other components, the present utility model realizes the firm connection between the second mating ring and the first mating ring, and firmly fixes the tire between these two rings. This structural design not only ensures the stable installation of the tire, but also improves the overall installation efficiency and reliability. BRIEF DESCRIPTION OF THE DRAWINGS
