Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casters, in particular to an industrial caster. Background Art
[0002] Shock-absorbing casters are mainly used in mobile containers such as trolleys and mobile pallets, including movable casters and fixed casters. Movable casters are commonly known as universal wheels, and their structure can rotate 360°, while fixed casters are also called fixed casters, which have no rotating structure and cannot rotate.
[0003] For example, Chinese patent application No. 202121357448.0 discloses an anti-entanglement industrial caster, which includes a wheel and an axle. The axle passes through the wheel and is rotatably connected to the wheel. A connecting frame is provided above the wheel, and the connecting frame is rotatably connected to the axle. The beneficial effect of the utility model is that during the use of the caster, the scraper cuts off the silk thread wrapped around the wheel, and the cleaning rod collides with the fine particles attached to the wheel to remove them, ensuring that the caster is not easily entangled and stuck during use.
[0004] In the above scheme, the roller can only move forward and backward in a certain direction, and cannot rotate 360 degrees horizontally, which is not flexible enough. If the existing universal wheel is used, the change of the steering knuckle of the universal wheel is not completely controlled. In many cases, due to the influence of various factors, the following direction of the steering knuckle may not be the accurate desired direction of movement conversion. In order to solve the above problems, we designed an industrial caster. Utility Model Content
