Abstract
Description
Technical Field
[0001] This utility model relates to the field of omnidirectional wheel technology, specifically to an omnidirectional double wheel. Background Technology
[0002] In today's logistics, warehousing, furniture moving, and other fields, casters are widely recognized as an important moving component due to their flexibility and convenience. However, traditional casters have a common problem: when carrying heavy objects, the wheels tend to roll, causing instability of the items outside of handling, increasing safety hazards and workload.
[0003] Most casters on the market currently use a fixed axle design, which keeps the wheel rolling even when carrying heavy loads. While this design facilitates movement, in certain situations, such as when temporarily securing items, performing delicate operations, or ensuring item stability, the rolling characteristic of traditional casters becomes inconvenient. Existing solutions include using caster brakes or fixing clamps. Foot-brake casters brake by contacting friction blocks with the wheel body, which to some extent affects the flexibility and lifespan of the caster.
[0004] Therefore, a universal dual-wheel design is needed to improve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a universal double wheel to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
