Technical Field

[0001] The utility model relates to the technical field of universal wheel testing, in particular to universal wheel aging testing equipment. Background Art

[0002] A universal wheel is a so-called movable caster, whose structure allows for 360-degree horizontal rotation. Casters are a general term that includes both movable and fixed casters. Fixed casters lack a swivel mechanism and cannot rotate horizontally, only vertically. These two types of casters are typically used in combination. For example, a trolley has two fixed wheels at the front and two movable universal wheels at the back, near the push handles.

[0003] Based on the above, the inventors found that the following problems exist: traditional testing equipment has poor adaptability to universal wheels of different sizes. In large-scale production, aging tests need to be performed on a large number of universal wheels of different sizes. If the equipment cannot quickly adapt to universal wheels of different sizes, it will seriously slow down the production progress and increase the time cost of product launch.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a universal wheel aging test equipment is provided to achieve a purpose with greater practical value. Utility Model Content

[0033] See also Figure 1 - Figure 5A Hall switch 1006 is installed on one side of the upper end of the mounting frame 1001, and a touch panel 1004 is installed on one side of the upper end surface of the mounting frame 1001.
