Caster wheel

Abstract

The invention provides a caster wheel, belongs to the technical field of machinery, and solves the problems of small damping range and poor buffering effect in the conventional damping spring caster wheel. The caster wheel comprises a foot stand capable of being mounted at the bottom of equipment and a wheel connected with the foot stand, wherein a through connection hole is formed in the side part of the foot stand; a transmission shaft capable of rotating is arranged at the connection hole; a buffer rod is arranged between the transmission shaft and the inner wall of the connection hole; the buffer rod is compressed under the action of gravity of the equipment; supporting plates are fixedly connected to the two ends of the transmission shaft; and the other ends of the supporting plates fixedly connected with the transmission shaft are connected with the wheel. The caster wheel has the advantages of good damping and buffering effects, long service life, simple structure and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a caster, in particular to a caster with buffer function. Background technique [0002] The so-called casters refer to the wheels that are connected to the lower part of the transportation device and can freely change the direction. They can be roughly divided into fixed casters and swivel casters. As an important part of many transportation equipment, casters are not only walking parts, but also have the function of shock absorption, especially in logistics places with uneven ground conditions. to a key influence. Especially for industrial casters, industrial casters mainly refer to a caster product used in factories or mechanical equipment, which require high impact resistance and strength.

AI Technical Summary

Problems solved by technology

[0003] At present, most industrial casters on the market generally use springs as shock absorbing devices. When designing casters, designers generally choose shock absorbing springs according to the maximum load of the casters. The effective shock absorbing range of casters with this structure is narrow, especially in the air. When there is no load or no other heavy objects are placed on the mechanical equipment, it can hardly play the role of shock absorption and buffering

However, when the mechanical equipment is relatively advanced or the price is relatively expensive, it has higher requirements for the cushioning performance of industrial casters. Industrial casters with shock-absorbing springs cannot better meet the requirements of these equipment for the cushioning performance of casters.
