Technical Field

[0001] The utility model belongs to the technical field of tires, and in particular relates to a cart tire which is not easily deformed. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They are usually installed on metal rims and can support the vehicle body, cushion external impacts, achieve contact with the road surface and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation.

[0029] In this embodiment, the rotating shaft 25 is first rotated, and the rotating shaft 25 drives the driving gear 26 to rotate. The driving gear 26 drives the screw 28 to rotate by meshing with the passive gear 27. The screw 28 drives the slider 29 to move in the moving hole 221.
