Universal caster with brake device

Abstract

The invention discloses a universal caster with a brake device. The universal caster comprises a support component and a wheel component, the support component comprises a mounting support and a wheel support, the mounting support is rotatably mounted on the wheel support, the wheel component comprises a tire and a hub, a tire is mounted on the hub, and the hub is mounted on the wheel component. The universal caster further comprises a brake component, the brake component comprises a driving part, a rotating disk, a cam mechanism and a brake part, wherein the driving part is associated with the rotating disk to drive the rotating disk to move, and the rotating disk is associated with the brake part through the cam mechanism to drive the brake part to move, so that the brake part is switched between a first position and a second position. At the first position, the brake part is matched with the hub, so that the universal caster is in a brake state. At the second position, the brake part is disengaged with the hub, so that the universal caster is in a movable state. The universal caster is convenient to operate and low in mounting space requirement.

Description

technical field [0001] The invention relates to a universal caster, in particular to a universal caster with a brake device. Background technique [0002] Swivel casters are widely used in industrial production, hospitals, supermarkets, and daily life. Due to their small size and high flexibility, it is very convenient for vehicles using swivel casters to move around in short distances. Among these swivel casters, quite a few of them require not only the function of turning at any angle, but also the ability to brake, especially both steering brakes and rotation brakes. [0003] According to the understanding and research, the main swivel casters with brake devices on the market are mostly in the form of wheel brakes. The principle is that there is a brake device on the caster bracket assembly, and the brake device has integrated or split brake pads. The brake pads can be tightly squeezed or attached to the wheel surface of the wheel body by external force, relying on the f...

Problems solved by technology

[0005] However, the above two types of brakes have disadvantages. The universal casters of the pedal device need to be operated one by one when braking or unlocking, and the steps are cumbersome; the universal casters driven by the linkage brake have strict requirements on the installation space and the application range is limited.

At the same time, the wheel surface brake requires the brake pads and the wheel surface to maintain a strong pressure, so that when multiple swivel casters need to be braked in conjunction, the mechanism design is very difficult, the parts have high strength requirements, and the reliability is not good.
