Universal wheel

Abstract

The invention discloses a universal wheel. The universal wheel comprises a universal wheel bottom plate (1) and universal wheel bodies (2), wherein universal wheel supports (4) are fixed at the bottom of the universal wheel bottom plate (1), and the universal wheel bodies (2) are fixed between the universal wheel supports (4); the universal wheel is characterized by also comprising a support plate (3) and a mounting shaft (5) fixed on the universal wheel supports (4), at least three universal wheel bodies are provided, and are matched on the support plate (3) in a rotating manner, the support plate (3) is matched on the mounting shaft (5) in a rotating manner, and the mounting shaft (5) is detachably connected with the universal wheel bottom plate (1). The invention provides the universal wheel which is simple in structure, high in reliability, convenient to assembly and disassembly, and adjustable in height and can easily pass over a barrier.

Description

technical field

[0001] The invention relates to the field of casters, in particular to a universal wheel. Background technique

[0002] With the rapid development of modern industry and logistics industry, casters are widely used, not only in factories, supermarkets, airports and warehouses, but also in homes. But generally, the working conditions of conventional swivel casters are very good, and the ground is very flat. However, under the bad situation of some road surfaces, such as pits, ridges or stair climbing, according to the prior art, ordinary wheels utilize three or more wheels to solve the above problems, but the structure Complicated, inconvenient to disassemble and assemble, ordinary wheels have poor flexibility and poor reliability. Contents of the invention

[0003] The technical problem to be solved by the present invention is: to overcome the above defects of the prior art, and provide a universal wheel with simple structure, high reliability, convenient ...
