[0002] Caster wheels are a general term, including swivel caster wheels, fixed caster wheels and swivel caster wheels with brakes. Swivel caster wheels, that is, the universal wheels we mentioned, have a structure that allows 360-degree rotation; fixed caster wheels, also called directional caster wheels, have no rotating structure and cannot rotate. Usually, these two types of caster wheels are generally used in combination. For example, the structure of a handcart is two directional wheels in the front and two universal wheels near the pushing armrest in the back;

[0003] Caster wheels are made of various materials, such as pp caster wheels, PVC caster wheels, PU caster wheels, cast iron caster wheels, nylon caster wheels, TPR caster wheels, iron core nylon caster wheels, iron core PU caster wheels, etc.;

[0004] Most of the existing mobile caster wheels have a single-shell structure design and no internal strengthening structure. Therefore, in actual use, the overall bearing capacity of the caster wheels is weak, and unilateral deviation wear is likely to occur after long-term use, affecting the overall use effect and service life of the wheel body. For this reason, the utility model proposes a high-strength mobile caster wheel. Content of the Utility Model
