[0032] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figures 1 to 3 , an embodiment provided by the present utility model: The wheel hub 1 presents a strong and thick structure, and a trolley tire 2 is carefully sleeved outside it. The trolley tire 2 has good elasticity and wear resistance, and a plurality of clearly visible wave patterns 3 are evenly arranged on its outside. These wave patterns 3 not only increase the friction between the tire and the ground, making the trolley more stable during driving, but also provide excellent grip under different road conditions. A plurality of reinforcing blocks 4 are fixedly connected to the inner side wall of the wheel hub 1 tightly. These reinforcing blocks 4 provide additional support and stability for the wheel hub 1. A unique trapezoidal opening is provided inside the reinforcing block 4. This trapezoidal opening design can not only reduce the weight of the reinforcing block 4, but also achieve better air circulation without affecting its strength, thereby reducing the temperature of the tire during operation. A connecting cylinder 5 is fixedly connected to the adjacent side of a plurality of reinforcing blocks 4 firmly. The inner wall of the connecting cylinder 5 is smooth and can achieve good rotational connection with the rotating shaft 6. Limit rings 7 are fixedly connected to both the front and rear ends of the rotating shaft 6. The sizes of these two limit rings 7 match the rotating shaft 6, which can effectively prevent the axial movement of the rotating shaft 6 and ensure its stability during operation. The adjacent sides of the two limit rings 7 are in close contact with the opposite sides of the connecting cylinder 5 respectively, providing stable support for the rotating shaft 6.

[0034] Referring to Figures 2 to 4, multiple balls 8 are movably connected to the middle of the rotating shaft 6. These balls 8 are round and smooth, playing a key role in reducing friction between the rotating shaft 6 and the connecting cylinder 5, enabling the rotating shaft 6 to rotate more smoothly and facilitating the transmission of lubricating oil. The outer parts of multiple balls 8 are all in close contact with the inner wall of the connecting cylinder 5, ensuring the smoothness of lubricating oil transmission. Both the front and rear ends of the top of the rotating shaft 6 are fixedly connected with rings 9. The rings 9 have a firm structure, and the inner wall is fixedly connected with threaded cylinders 10. The outer part of the threaded cylinder 10 is threadedly connected with a sealing component for sealing the threaded cylinder 10. The sealing component includes a threaded cap 11. The inner wall of the threaded cap 11 is carefully designed to have a threaded structure matching the outer part of the threaded cylinder 10 and can be tightly threadedly connected to the outer part of the threaded cylinder 10, playing a good sealing role. The bottom side of the threaded cap 11 is fixedly connected with a sealing ring 12. The sealing ring 12 can closely fit on the outer part of the threaded cylinder 10, and during the rotation of the threaded cap 11, the sealing ring 12 can rotate together with the threaded cap 11 and always maintain close contact with the threaded cylinder 10, ensuring the reliability of the seal. The outer part of the sealing ring 12 is rotatably connected to the outer part of the threaded cylinder 10, and the bottom side of the sealing ring 12 is in close contact with the top side of the ring 9, further enhancing the sealing effect.

[0035] Refer to Figure 1 , Figure 5 and Figure 6 , a connecting plate 14 is fixedly connected to the top side of two brackets 13. The connecting plate 14 is flat and firm, and multiple square openings 15 are provided on the bottom side, providing space for the subsequent components to rotate. A plurality of rotating columns 16 are rotatably connected to the bottom end of the connecting plate 14. The rotating columns 16 can rotate flexibly and are used to clean the inside of the wavy pattern 3. A rotating rod 17 is fixedly connected to the bottom side of the rotating column 16, and the bottom end can be accurately slidably connected to the inside of the wavy pattern 3. As the cart tire 2 rotates, the rotating rod 17 slides in the wavy pattern 3 to clean the stuck stones. Assembly components for assembling the cart tire 2 are fixedly connected to both the front and rear sides of the rotating shaft 6. The assembly components include connecting columns 18. The bottom ends of the two brackets 13 are respectively rotatably connected to the outer parts of the two connecting columns 18. The size of the connecting columns 18 matches the bottom ends of the brackets 13, enabling stable rotational connection. The closer sides of the two connecting columns 18 are respectively fixedly connected to the farther sides of the rotating shaft 6, ensuring the firmness of the connection. Limit disks 19 are fixedly connected to the farther sides of the two connecting columns 18. The diameter of the limit disks 19 is larger than the diameter of the connecting columns 18, which can effectively prevent the brackets 13 from moving in the axial direction and ensure the stability of the assembly;

[0036] A powerful spring 20 is sleeved outside the connecting column 18. The powerful spring 20 has a high elastic coefficient and can provide sufficient elastic force for the assembly process. A limiting cylinder 21 is slidably connected to the outside of the connecting column 18. The inner wall of the limiting cylinder 21 is smooth and can slide smoothly on the connecting column 18. The adjacent ends of the two powerful springs 20 are respectively fixedly connected to the adjacent sides of the inner walls of the two limiting cylinders 21, and the opposite ends of the two powerful springs 20 are respectively fixedly connected to the adjacent sides of the two limiting plates 19. The setting of the powerful spring 20 enables the limiting cylinder 21 to move within a certain range, providing flexibility for the assembly process. The outside of the limiting cylinder 21 is slidably connected to the inner wall of the limiting plate 19, ensuring the stable movement of the limiting cylinder 21 in the axial direction. The outside of the limiting cylinder 21 is rotatably connected to the inner wall of the bottom end of the bracket 13, enabling the bracket 13 to rotate flexibly. Pull rings 22 are fixedly connected to the opposite sides of the two limiting cylinders 21. The design of the pull rings 22 facilitates the operation of the user during the assembly process. Two limiting blocks 23 are fixedly connected to the bottom ends of the adjacent sides of the two brackets 13. The adjacent sides of every two limiting blocks 23 are in close contact with the outside of one of the threaded caps 11, which can effectively prevent the threaded cap 11 from loosening during operation and ensure stable rotation.

[0037] Working principle: The connecting cylinder 5 is restricted between the outside of the rotating shaft 6 and the two limiting rings 7, and then the connecting columns 18 on both sides of the rotating shaft 6 are clamped inside the bracket 13. At this time, hold the pull ring 22 and drive the limiting cylinder 21 to slide, and then compress the powerful spring 20 so that the powerful spring 20 can store elastic potential energy, and then give the limiting cylinder 21 a force in the opposite direction. After pulling the limiting cylinder 21 to be misaligned with the bracket 13, the connecting column 18 can be driven to slide upward at the bottom end of the bracket 13. After the connecting column 18 slides to abut against the bracket 13, release the force on the pull ring 22. At this time, the limiting cylinder 21 will be subjected to the restoring force of the powerful spring 20 and be clamped inside the limiting cylinder 21, thus completing rapid assembly and improving the assembly efficiency. At the same time, by holding the threaded cap 11 and applying a counterclockwise force to drive the sealing ring 12 to rotate. After the sealing ring 12 rotates to be disengaged from the threaded cylinder 10, the threaded cylinder 10 is exposed at this time. At this time, lubricating oil can be poured into the inside of the rotating shaft 6 in advance, and then the threaded cap 11 is fixed to the outside of the threaded cylinder 10 in the clockwise direction and the sealing ring 12 is made to fit with the ring 9, so as to avoid the volatilization of the lubricating oil. The lubricating oil will contact the ball 8 inside the rotating shaft 6, and the connecting cylinder 5 will contact the ball 8 after rotation, so that the ball 8 can transfer the lubricating oil to the connecting cylinder 5, thereby reducing the wear of the connecting cylinder 5 during rotation and eliminating the need to frequently apply lubricating oil to the connecting cylinder 5, thus reducing the operation steps and improving the work efficiency.

[0038] Then, when the tire 2 drives the reinforcement block 4 and rotates around the rotating shaft 6 by using the connecting tube 5, the wave pattern 3 on the surface of the tire 2 is used to increase the friction during use to improve the stability of the tire 2. At the same time, the rotating column 16 is driven by the rotating rod 17 to make a circular arc motion back and forth around the rotating column 16 as the center. As the tire 2 rotates, the wave pattern 3 is used to guide the movement of the rotating rod 17, so that the rotating rod 17 can clean up the stones inside the wave pattern 3 provided on the tire 2, thereby avoiding the deformation of the tire 2 caused by the long-term presence of stones, thereby extending its service life.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
