Description

Compression stability tester for bicycle rim Technical Field The utility model relates to the technical field of bicycle rim testing, in particular to a bicycle rim compression stability testing machine. Background Bicycles, also known as bicycles or scooters, are typically two-wheeled small land vehicles. The bicycle can also be used as an environment-friendly transportation means for riding instead of walking and going out. The body part of the bicycle mainly comprises a frame, a front fork, a handlebar, a saddle, a front fork assembly and the like. The transmission part of the bicycle comprises pedals, a crank, a chain wheel, a chain, a middle shaft, a flywheel and the like, and the pedals are stepped on by manpower. The running portion of a bicycle generally includes front and rear wheels, front and rear axle members, spokes, rims (wheels), tires, and the like. The traditional detection means of the compression stability of the bicycle rim is simpler, most of the detection means are judged by means of manual experience, whether the appearance of the rim is obviously deformed or not is observed, or the rim is subjected to simple extrusion test, but the methods cannot accurately measure specific performance parameters of the rim under different pressure conditions, and the compression stability of each part of the rim is difficult to comprehensively detect. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a bicycle rim compression stability testing machine, which solves the problems that the traditional bicycle rim compression stability testing means is simpler, the traditional bicycle rim compression stability testing means is mostly judged by relying on manual experience, whether the appearance of the rim is obviously deformed or not is simply tested by extrusion, but the methods cannot accurately measure specific performance parameters of the rim under different pressure conditions, and the compression stability of each part of the rim is difficult to comprehensively detect.
