Bullet train pantograph gas path flow direction and principle display practical teaching device

The utility model relates to the field of function demonstration equipment, and discloses a bullet train pantograph gas path flow direction and principle demonstration practical training teaching device comprising an air storage cylinder, the other side of the air storage cylinder is provided with a pantograph model, and the other side of the pantograph model is provided with a barometer. The pantograph lifting control pipeline simulates a real vehicle in a one-to-one manner, so that a learner can clearly see a pantograph structure without buckling the vehicle, and meanwhile, the pantograph lifting control pipeline is moved to a platform, so that the principle of a gas circuit can be intuitively displayed, corresponding actions can be displayed, the requirements of teaching and practical training can be met, and the practicability of the device is greatly improved; the pantograph lifting control pipeline is demonstrated on site, and independent operation of occupying maintenance time in a real vehicle in each
