Description

Universal wheel

Technical Field

The invention relates to the technical field of universal wheels, in particular to a universal wheel.

Background

The caster is a general term and comprises a movable caster and a fixed caster. The movable caster is a universal wheel, and the fixed caster is also called a directional wheel, and has no rotating structure and can not rotate. Because the universal wheel can rotate, instability is increased, and in some use occasions, the caster needs to be locked. The universal caster wheel lock comprises two aspects, one is to prevent the caster wheel from walking; one to prevent the caster from swinging. Generally, a caster with a braking function is basically composed of a body and a wheel body pivoted to the body, a cam, a brake disc and a brake block are arranged between the body and the wheel body, and the brake block is pressed on a tire to brake by moving down the brake disc.

The fixed caster is also called a directional caster, and has no rotating structure and can not rotate. Conventional casters typically secure the wheels to the frame via an axle. The caster support is complex in structure and multiple in parts, and great obstruction is caused to mold design and caster assembly. Therefore, a need exists for a new caster structure.
