Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of bicycle saddle antifatigue test device.
The technical matters that the utility model further solves is to provide a kind of bicycle saddle antifatigue test device, comprises base, fixed mount, electromagnet, iron block, pressure assembly and controller, and described base is provided with deck panels and lower floor's panel; Described fixed mount is fixed on the top of described upper deck panels; Described pressure assembly is through described upper deck panels, and its top is connected with iron block; Described lower floor panel is fixed with saddle holder; Described electromagnet hangs the top being fixed on described fixed mount; Electromagnet described in described controller control linkage.
The utility model is relative to prior art, and the pressure that bicycle saddle is suppressed by suppressing component passes, the fluctuation range that is stressed of bicycle saddle is little, and the experimental result of endurance test is accurate.
As the further improvement of a kind of bicycle saddle of the utility model antifatigue test device, in order to avoid the Density inhomogeneity of iron block, in the process of freely falling body, tilted upward amplitude affects experimental result too greatly, and described iron block slides in described can descending in described fixed mount.In this embodiment, also can be fixed with transparent baffle in the surrounding of described fixed mount and solve this problem.
According to a preferred embodiment of the present utility model, described pressure assembly comprises long tube and is fixed on the compression block of long tube upper and lower end parts and suppresses block.
As the further improvement of a kind of bicycle saddle of the utility model antifatigue test device, described upper deck panels is provided with for the up and down through hole of described long tube, in order to limit the up and down of long tube, the diameter of described through hole and the difference range of described long tube external diameter are 1mm-3mm.
As the further improvement of a kind of bicycle saddle of the utility model antifatigue test device, in order to make the uniform force of saddle true, described in suppress block lower surface be the arc-shaped of mutually coincideing with the shape of the upper surface of saddle.
As the further improvement of a kind of bicycle saddle of the utility model antifatigue test device, the below of described base is lined with flexible pad, and described flexible pad can avoid the floor of this proving installation to workplace to cause damage.
Except technical matters, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the utility model described above solves, the advantage that the other technologies feature comprised in the other technologies problem that a kind of bicycle saddle antifatigue test device of the utility model can solve, technical scheme and these technical characteristics bring, will be described in further detail by reference to the accompanying drawings.
The advantage that the utility model has and good effect are: because the utility model adopts as above technical scheme, in the endurance test of bicycle saddle, bicycle saddle is forced through pressure assembly transmission, uniform force, the utility model also tentatively can limit the path that moves up and down of iron block, further ensures the accuracy of experiment; Therefore the utility model structure is simple, effectively can avoid the fluctuating factor in testing, therefore improve accuracy and the reliability of experiment.
