The invention has the beneficial effects as follows: the present invention is simple in structure, and convenient test can realize the accurate detection to the fatigue strength of bicycle handle bar, realizes controlling automatically, analyzing and to load, and the quality of the accessory that guaranteed to dispatch from the factory is good, has guaranteed bicyclist's personal safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done concrete being described below.
Fig. 1 is a structural representation of the present invention.As shown in the figure, dynamic fatigue test machine for bicycle handle bar of the present invention, comprise body 11, guide plate 10, handle riser anchor clamps 9, transverse tube anchor clamps 8, force transducer 7, displacement transducer 5, cylinder 4, support 3, lifting screw 2, handwheel 1 and crossbeam 6, support 1 adopts the gate-type structure, be fixed on the body 11, seal in lifting screw 2 on the top board of support 3 downwards, handwheel 1 matches with lifting screw 2, and is located at the top of top board.At the lower end of lifting screw 2 fixed cross beam 6, the two ends of crossbeam 6 are provided with stationary installation (not shown), crossbeam 6 is adjusted to a suitable position after, by stationary installation crossbeam 6 is fixed up.
Fix two cylinders 4 on crossbeam 6 respectively, the piston rod of cylinder 4 connects transverse tube anchor clamps 8 on its top down, and displacement transducer 5 and force transducer 7 are set on the piston rod of cylinder 4.In order to adapt to the different angles between transverse tube anchor clamps 8 and the handlebar test specimen, between the piston rod of transverse tube anchor clamps 8 and cylinder 4, ball-joint is set, can be so that can change the angle of transverse tube anchor clamps 8 as required.In body 11, stable-pressure device is set, stable-pressure device links to each other with cylinder 4 by pipeline, on pipeline, be provided with solenoid valve, solenoid valve, displacement transducer 5, force transducer 7 usefulness signal wires are linked to each other with outer computer, the signal of being gathered is passed to outer computer, and by the action of outer computer control electromagnetic valve, and show real time data.
