[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 、 Figure 3 、 Figure 4 As an embodiment provided by the present invention: a trolley tire with a self-locking function includes a fixed plate 1. A plurality of bolts 2 are threadedly connected inside the fixed plate 1 to firmly connect the fixed plate 1 to the trolley, ensuring stability and safety. A support frame 3 is fixedly connected to the bottom of the fixed plate 1. The support frame 3 provides a structural framework for supporting and positioning the tire. A wheel 4 is rotatably connected inside the support frame 3 and is fixedly connected to the inside of the drive assembly to provide the necessary power and movement ability. The wheel 4 is fixedly connected to a drive assembly that provides a telescopic force inside. The drive assembly includes a cylinder 5. The driving end of the cylinder 5 is fixedly connected to two telescopic columns 6. A spring 7 is sleeved outside the telescopic column 6 to increase the stability and buffering ability of the telescopic column 6. The other end of the spring 7 is fixedly connected to the outside of the clamping column 8. The outside of the rotating column 9 is rotatably connected inside the clamping column 8. One end of the spring 7 is outside the cylinder 5. Two clamping columns 8 are fixedly connected to the outside of the drive assembly to limit the tire. A connecting column 17 is rotatably connected inside the clamping column 8. A plurality of rotating columns 9 are fixedly connected to the outside of the connecting column 17. Clamping blocks 10 are fixedly connected to the outside of the rotating columns 9, enabling the tire to firmly grip the ground and providing better traction and stability;

[0032] Refer to Figure 1 、 Figure 2, a rotating column 11 is slidably connected to the outside of the clamping block 10. The rotating column 11 slides freely on the clamping block 10 to adapt to different ground conditions. A groove 12 is formed inside the rotating column 11 to provide additional clamping function and increase structural strength. Two holes 13 are formed inside the wheel 4, and the outside of the telescopic column 6 is slidably connected inside the holes 13, so that the wheel 4 can move accordingly with the movement of the telescopic column 6 to adapt to different driving states. A plurality of Z-shaped convex grooves 14 are fixedly connected to the outside of the wheel 4, and a plurality of circular convex grooves 15 are fixedly connected to the outside of the wheel 4. The material of the Z-shaped convex groove 14 is polyurethane, which helps to provide stable traction on various surfaces. The material of the circular convex groove 15 is polyester fiber, which can provide a certain buffering effect while ensuring the tire structure, providing an anti-slip effect. Soft hairs 16 are fixedly connected to the outside of the circular convex groove 15 to provide additional adhesion.

[0033] Working principle: First, when it is necessary to stop the trolley, the air cylinder 5 is started, so that the telescopic columns 6 at both ends of the air cylinder 5 move backward simultaneously, thereby driving the connecting column 17 fixedly connected thereto to roll backward inside the clamping column 8. Then, under the action of the backward force of the clamping block 10 fixed to the connecting column 17, it contracts inward, so that the clamping block 10 is stuck at the groove 12 inside the rotating column 11 and applies a fixed force to it, thereby changing the two rotating columns 11 from a rotating state to a stationary state, and then the wheels also stop accordingly. Therefore, the one-key self-locking function of the trolley tire is realized, ensuring that it is more convenient for users during use.

[0034] Due to the presence of a plurality of Z-shaped convex grooves 14 on the surface of the wheel, and its material is polyurethane, with wear-resistant and anti-slip characteristics, and there are also a plurality of circular convex grooves 15 which are beautiful. There are also soft hairs 16 on the surface of the circular convex groove 15, and the material of the circular convex groove 15 is polyester fiber, which enhances the strength and wear resistance of the tire, provides additional anti-slip. Under the dual action of physics and material, the anti-slip and anti-wear effects of the trolley tire are realized.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
