Description

Technical Field

[0001] The utility model relates to the technical field of caster application, in particular to a caster integrally formed with a bottom plate of a transport equipment. Background Art

[0002] During the manufacturing process of the one-piece base, all parts are formed at one time through a continuous material flow, so there are no welding points or connectors, which greatly enhances its overall structural strength. This sturdy structure can withstand greater weight and impact, ensuring the stability and durability of the caster and being able to withstand greater loads. This is especially important for equipment that needs to be moved frequently and carry heavy objects, and can ensure the stability and safety of the equipment during movement. The one-piece base is usually designed with standard mounting holes and interfaces, making the installation process of the caster simple and quick.

[0003] In the related art, a universal caster with a brake is usually braked by friction between a brake spring and a roller, and the brake spring and the outer surface of the roller are in contact to brake the wheel, thereby realizing the braking function of the universal caster. However, when the speed is fast or the load is heavy, the deformation of the brake spring is large during braking, and the braking performance is unstable. How to improve the stability of the braking effect is a problem that needs to be discussed and solved urgently.

[0004] The existing patent (publication number: CN220923700U) is a caster, which is provided with a plurality of grooves on the side of the brake spring plate facing the single wheel and a strip boss is formed on the side of the brake spring plate facing the brake bracket, so that the brake spring plate passes through the strip boss structure during braking, thereby increasing the deformation resistance of the brake spring plate, so that the brake spring plate can be more stably abutted against the single wheel during braking, thereby improving the stability of the braking effect, and due to the increase in deformation resistance, the service life of the braking function is increased.

[0005] In view of the above problems, existing patents have provided solutions. The base plates of existing casters are mostly formed by segmented processing and welding, and are connected and fixed with bolts during installation, which reduces the overall strength and makes the installation process complicated.

[0006] To this end, a caster with an integrally formed bottom plate of a transport equipment is proposed. Utility Model Content
