Description

Technical Field

[0001] This application relates to the technical field of casters, and more particularly, to a light-duty double universal caster. Background Art

[0002] A universal caster is short for a swivel caster, and its structure allows for 360-degree horizontal rotation. Casters is a general term that includes fixed casters, swivel casters, and swivel brake casters. Fixed casters do not have a rotating structure and cannot rotate horizontally but only vertically. These two types of casters are generally used in combination. For example, the structure of a handcart has two fixed wheels at the front and two swivel universal casters near the pushing armrest at the back.

[0003] A universal caster refers to a caster whose bracket can rotate 360 degrees horizontally under dynamic or static loads. There are various materials for manufacturing universal casters, and the most common materials are nylon, polyurethane, rubber, cast iron, etc. They are widely used in many industries and various fields such as mines, mechanical equipment, electronic equipment, medical equipment, engineering decoration, textiles, printing and dyeing, furniture, logistics equipment, warehousing, turnover carts, chassis, cabinets, equipment, electromechanics, dust-free workshops, production lines, large supermarkets, etc. According to their different uses, the bearings are divided into iron cores, aluminum cores, and plastic cores, with sizes ranging from 1 inch to 8 inches. Among them, iron cores and aluminum cores are generally heavy-duty load-bearing wheels and are often equipped with braking devices when in use.

[0004] After the universal caster on the market is installed and fixed, when the roller needs to be replaced, it is basically necessary to directly replace the entire universal caster, and tools are also required for replacement, which is rather troublesome to operate. Moreover, replacing the entire universal caster increases the maintenance cost, so there are deficiencies. Utility Model Content

[0005] To make up for the above deficiencies, the present utility model provides a light-duty double universal caster, aiming to improve the problem that when the roller needs to be replaced after the universal caster on the market is installed and fixed, it is basically necessary to directly replace the entire universal caster, and tools are also required for replacement, which is rather troublesome to operate, and replacing the entire universal caster increases the maintenance cost.
