Description

Technical Field

[0001] This utility model relates to the field of level testing machine technology, and in particular to a level testing machine for shock-absorbing front forks. Background Technology

[0002] In recent years, high-performance mountain bikes and road bikes have become increasingly popular among consumers. These bikes, operating on complex terrain, place extremely high demands on the performance and precision of their suspension forks. They require not only excellent shock absorption but also precise fork leveling to ensure riding stability and handling. To improve product quality and market competitiveness, bicycle manufacturers need to conduct rigorous quality testing on suspension forks. Leveling, as a crucial quality indicator for suspension forks, directly impacts the overall performance and safety of the bicycle. Therefore, efficient and precise testing equipment is essential to ensure consistent product quality.

[0003] Currently, most level testing machines on the market consist of a test bench and a test stand. In the early stages of bicycle production and repair, the levelness of suspension forks was mainly determined by simple hand tools and experience. A ruler or level was placed against the suspension fork, and its levelness was judged by visual inspection. This method was not only inaccurate but also highly susceptible to human factors, making it difficult to accurately measure minute level deviations. With the development of cycling, especially the popularization of high-performance mountain bikes and road bikes, riders have increasingly higher requirements for bicycle handling and comfort. As one of the key factors affecting the riding experience, the levelness of the suspension fork directly relates to the stability and steering precision of the bicycle during riding. Therefore, a high-precision and high-efficiency testing device is needed to ensure that the levelness of the suspension fork meets the requirements. Utility Model Content
