[0027] As Figure 6As shown in the figure, a stepping fatigue test device according to an embodiment of the present invention includes a frame 20 for fixing a special trampling type toilet for rail transit to be detected, a driving cylinder 21 arranged on the frame 20, and an electric control box 23. A shaft rod 22 is fixed to the shaft end of the cylinder shaft of the driving cylinder 21, and the shaft rod 22 is connected to a lever 11.

[0028] This toilet realizes flushing by stepping, which is convenient to use. In addition, the structure design without a water tank reduces the overall volume, and the structure design of the flip cover mechanism also meets the design requirements for odor sealing; the actions of the drainage and flip cover mechanisms can be controlled simultaneously by stepping on the lever, with a clever design; this stepping fatigue test device realizes the durability detection of this special trampling type toilet for rail transit through an electric control program, greatly reducing the labor intensity of manual detection.

[0029] During specific use, for the convenience of understanding the present invention, it is described in conjunction with the accompanying drawings;
