[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A lightweight cart tire includes a rubber ring 1 and a support hub 3. The rubber ring 1 is an integrated annular structure and is sleeved on the outside of the support hub 3. The middle of the support hub 3 is rotatably connected to a convex shaft 8 via a bearing 7. The outer wall of the curved end of the rubber ring 1 is integrally formed with multiple groups of convex patterns 2, and the multiple groups of convex patterns 2 are distributed in an annular pattern.

[0025] The first split 301 and the second split 302 are combined and fixed by the locking rod 6 to realize the composition of the support hub 3. Then the integrated rubber ring 1 is put on the outside of the support hub 3. The split support hub 3 increases the flexibility of the hub. Combined with the hollow design of the support hub 3, the designer can more flexibly choose the combination of materials and structures to reduce the total weight of the hub without sacrificing strength. The convex pattern 2 designed on the outer wall of the rubber ring 1 replaces the traditional anti-skid groove, which can effectively prevent the tire from slipping while effectively placing sand and gravel in the embedding, thereby ensuring the stability of the cart tire.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the front end surface of the convex shaft 8 is higher than the front end surface of the bearing 7, and the inner surface wall of the supporting hub 3 is rotatably connected to the convex shaft 8 through the bearing 7. The convex shaft 8 is connected to the shaft rod on the external vehicle body through the convex shaft 8. The convex shaft 8 protrudes a certain amount compared to the bearing 7, which can avoid collision between the external vehicle body and the tire, thereby further ensuring the stability of the lightweight cart tire.

[0027] It should be noted that the bearing 7 is made of plastic material, and the plastic material is preferably BBS, FRPP and CPVC;

[0028] Specifically, such as Figure 2 and Figure 3As shown, the support hub 3 includes a split 1 301 and a split 2 302, and the split 1 301 and the split 2 302 are fixedly connected by a locking rod 6. Both the split 1 301 and the split 2 302 are hollowed out. The split support hub 3 increases the flexibility of the hub. Combined with the hollow design of the support hub 3, the designer can more flexibly choose the combination of materials and structures to reduce the total weight of the hub without sacrificing strength. The inner walls of the split 1 301 and the split 2 302 are fixedly connected with reinforcing ribs to ensure the structural strength of the split 1 301 and the split 2 302 themselves. The front end face of the split 2 302 is fixedly connected with a convex ring 4, and the inner wall of the convex ring 4 is engaged with the rear end face of the split 1 301 through the annular groove 5, so as to achieve a quick and stable combination of the split 1 301 and the split 2 302.

[0029] Working principle: Merge the split part 1 301 and the split part 2 302 and fix them by the locking rod 6 to realize the composition of the support hub 3, and then put the integrated rubber ring 1 onto the outside of the support hub 3. The split support hub 3 increases the flexibility of the hub. Combined with the hollow design of the support hub 3, the designer can more flexibly choose the combination of materials and structures to reduce the total weight of the hub without sacrificing strength. The convex pattern 2 designed on the outer wall of the rubber ring 1 replaces the traditional anti-skid groove, which can effectively prevent the tire from slipping while effectively placing sand and gravel, thereby ensuring the stability of the cart tire. The inner wall of the support hub 3 is rotatably connected to the cam 8 through the bearing 7, and is connected to the shaft rod on the external vehicle body through the cam 8. The cam 8 has a certain protrusion compared to the bearing 7, which can avoid collision between the external vehicle body and the tire, thereby further ensuring the stability of the lightweight cart tire.
