[0028] like Figures 1 to 6 As shown, it includes a steel ring body 2, a surface array of the steel ring body 2 is provided with a support assembly 3 for supporting the tire, the surface of the steel ring body 2 is provided with an adjustment assembly 1 for adjusting the position of the support assembly 3, and the adjustment assembly 1 is movably connected to the steel ring body 2.

[0029] Under the action of the adjustment component 1, the support component 3 can be moved and adjusted along the radius of the steel ring body 2. When the moving distance of the support component 3 exceeds the radius of the steel ring body 2, the overall length and diameter of the steel ring will change. When the tire is installed, the support component 3 can apply pressure to the inside of the tire, thereby increasing the contact area between the tire and the ground and improving the practicality of the steel ring.

[0030] like Figure 2 and Figure 5 As shown, the adjustment component 1 includes an adjustment ring 105, and the adjustment ring 105 is rotatably connected to the steel ring body 2, the surface array of the adjustment ring 105 is provided with an arc groove 101, and the arc groove 101 runs through the surface of the adjustment ring 105, the side of the adjustment ring 105 is provided with an adjustment groove 106, and a gear bar 104 is provided in the adjustment groove 106, an adjustment motor 102 is fixed on the surface of the steel ring body 2, and a transmission gear 103 is provided at the output end of the adjustment motor 102, and the transmission gear 103 and the gear bar 104 are meshed with each other.

[0031] In the adjustment component 1, under the drive of the adjustment motor 102, the transmission gear 103 at the output end of the adjustment motor 102 meshes and rotates with the gear bar 104 in the adjustment groove 106 on the surface of the adjustment ring 105, and then the adjustment ring 105 rotates, and at the same time, the arc groove 101 on the surface of the adjustment ring 105 moves and adjusts with the support component 3.

[0032] like Figure 1 , Figure 2 and Figure 6 As shown, the support assembly 3 includes an adjusting rod 306, a push rod 307 is fixed on the surface of the adjusting rod 306, and the push rod 307 is movably connected to the arc groove 101, a buffer groove 305 is opened at the top of the adjusting rod 306, a movable rod 303 is arranged in the buffer groove 305, and the movable rod 303 is movably connected to the buffer groove 305, a support plate 302 is fixed to the top of the movable rod 303, balls 301 are evenly arranged on the top surface of the support plate 302, a buffer spring 304 is arranged in the buffer groove 305, and the two ends of the buffer spring 304 are respectively fixedly connected to the movable rod 303 and the buffer groove 305.

At the same time, the arc groove 101 on the surface of the adjustment ring 105 moves and adjusts the support component 3. When the arc groove 101 in the adjustment component 1 moves with the push rod 307 and the adjustment rod 306, the movable rod 303 and the support plate 302 will move outward from the steel ring body 2. When the tire is installed on the surface of the steel ring body 2, the support plate 302 can support the inner side of the tire, and the ball 301 on the surface of the support plate 302 can reduce the friction between the tire and the support plate 302, and the buffer spring 304 in the buffer groove 305 can absorb the shaking of the steel ring body 2 during rolling to avoid damage to the movable rod 303 and the support plate 302.
