The utility model is achieved through the following technical solutions above-mentioned purpose:
Bicycle saddle fatigue tester, for carrying out testing fatigue to bicycle saddle, comprise frame, saddle fixing device, measurement mechanism, hold down gag and drive unit, saddle fixing device, measurement mechanism, hold down gag and drive unit are all contained in frame, saddle is fixed on saddle fixing device by saddle pipe, drive unit connects hold down gag and drives hold down gag to be compressed by saddle, drive unit connects hold down gag by measurement mechanism, the pressure that measurement mechanism is subject to for measuring saddle.
As preferably, described frame is horizontal base, and the equal level of saddle fixing device, measurement mechanism, hold down gag and drive unit is arranged in frame.
As preferably, described frame is vertical support, and saddle fixing device, measurement mechanism, hold down gag and drive unit are all vertically mounted in frame.
As preferably, described saddle fixing device comprises saddle pipe supporting seat, support limit stop, and saddle pipe horizontal positioned is also supported by saddle pipe supporting seat, and one end of saddle pipe connects saddle, and the other end of saddle pipe connects support limit stop; The connecting portion of described saddle pipe and support limit stop is provided with the second pressure transducer.
As preferably, described hold down gag comprises saddle pressure head, guide pole and linear axis bearing, and guide pole is arranged on base by linear axis bearing, and one end of guide pole connects saddle pressure head, and the other end connects measurement mechanism.
As preferably, described measurement mechanism comprises the first pressure transducer, a Y word joint, the 2nd Y word joint, the first oscillating bearing and second joint bearing, one end of first pressure transducer connects the first oscillating bearing by a Y word joint, the other end connects second joint bearing by the 2nd Y word joint, and second joint bearing connects hold down gag by shaft coupling.
As preferably, described drive unit comprises driving cylinder, drives the piston rod of cylinder to connect measurement mechanism.
As preferably, described first sensor is BLR-1 type sensor.
As preferably, described frame is made up of aluminium section bar.
As preferably, the piston rod of described driving cylinder, the first pressure transducer, guide pole and saddle pipe axle center are on same straight line.
The beneficial effects of the utility model are: the testing efficiency of this fatigue tester is high, structure is simple, cost is low, easy to manufacture; The utility model is the special fatigue tester of bicycle saddle, can detect, ensure that the outgoing of saddle before saddle dispatches from the factory to the fatigue strength of seat cushion and serviceable life; By the pressure regulating BLR-1 type sensor to export different size, the body weight that everyone is different can be simulated, detects the fatigue strength of bicycle saddle under different pressures size, applied widely; The saddle pipe of bicycle saddle cushion can be clamped by lower clamp and upper fixture, by changing retaining part, test machine can be made to be applicable to the saddle of various sizes.
