2. The treadmill for physical training of claim 1, wherein: the cylinder walls of the left telescopic cylinder (24) and the right telescopic cylinder (28) are made of natural latex, imitation latex, TPE or PVC materials with corrugated or sawtooth-shaped cross sections, and the left telescopic cylinder (24) and the right telescopic cylinder (28) can stretch along the axis direction.
3. Use of a treadmill for physical training as claimed in claim 2 wherein:
when no sporter exists on the tape running platform (43), the front end of the tape running platform (43) tilts upwards by a preset gradient under the elastic return action of the left return spring (16) and the right return spring (11); when a sportsman runs on the running belt platform (43), when the sportsman pedals the running belt (71) downwards with feet, under the impact of the foot pedal of the sportsman, the front end of the running belt platform (43) can downwards drive the buffer board (3) to downwards displace for a certain distance, and when the sportsman is separated from the running belt (71), the front end of the running belt platform (43) can upwards tilt up a preset gradient again under the rebounding action of the left return spring (16) and the right return spring (11); meanwhile, the roller (81) at the tail end of the tape running platform (43) can roll on the ground adaptively;
when the sporter continuously runs on the running belt (71), the buffer board (3) can periodically move downwards and rebound upwards;
in the process that the buffer plate (3) is impacted by pedals to move downwards, the left connecting rod (18) and the right connecting rod (32) are driven by the buffer plate (3) to move to synchronously approach the left slider (2) and the right slider (8) in opposite directions through the downward displacement of the buffer plate (3), the left push rod (21) and the right push rod (7) are driven by the left slider (2) and the right slider (8) to move in opposite directions respectively to drive the left disc body (4) and the right disc body (6) to move in opposite directions, the left telescopic cylinder (24) and the right telescopic cylinder (28) are driven by the left disc body (4) and the right disc body (6) to contract in the axial direction through the movement in opposite directions, so that the volume of the damping air chamber (47) is rapidly reduced, the air in the damping air chamber (47) is instantly compressed, the compressed air in the damping air chamber (47) cannot instantly enter the flow dividing chamber (49) through the second one-way valve (48) in the air guide channel (50), therefore, the rebound force of the left disc body (4) and the right disc body (6) is formed in the damping air chamber cavity (47), the trend that the left disc body (4) and the right disc body (6) are continuously close to each other is buffered and restrained, and the buffer effect of the buffer plate (3) moving downwards is further achieved, meanwhile, in the process that the air in the damping air chamber cavity (47) is compressed, part of the compressed air can enter the shunting cavity (49) through a second one-way valve (48) in the air guide channel (50), so that the effect of continuously weakening the rebound force of the damping air chamber cavity (47) on the left disc body (4) and the right disc body (6) is achieved, the phenomenon that the rebound force of the damping air chamber cavity (47) is larger and larger after being compressed is prevented, and the damping and buffering process of the buffer plate (3) is more stable;
when the buffer plate (3) moves upwards, under the rebound action of the return spring (16) and the right return spring (11), the left disc body (4) and the right disc body (6) start to move away from each other, so that the left telescopic cylinder (24) and the right telescopic cylinder (28) both move in a relaxation mode along the axis direction, at the moment, negative pressure is formed in the shock absorption air chamber cavity (47) due to the increase of the volume, the rebound speed of the springs is weakened, the shock intensity of the buffer plate (3) due to the upward rebound of the return spring (16) and the right return spring (11) is relieved, meanwhile, under the negative pressure action in the shock absorption air chamber cavity (47), external air enters the shock absorption air chamber cavity (47) through a first one-way valve in the vent pipe (26), and the air pressure in the shock absorption air chamber cavity (47) is kept to be the same as the large air pressure;
along with the continuous running of the running sporters, the left telescopic cylinder (24) and the right telescopic cylinder (28) can be periodically contracted and expanded, so that the pressurized air is continuously fed into the shunting cavity (49), the pressurized air in the shunting cavity (49) can be continuously shunted to the left air guide channel (41) and the right air guide channel (42), and finally the positive pressure air is continuously formed in the left air collection chamber (39) and the right air collection chamber (33); finally, the pressurized air in the left air collection chamber (39) and the right air collection chamber (33) is sprayed out through the air outlets (40), and the airflow sprayed out from the air outlets (40) is blown to the runner running on the running belt (71) to blow air and cool the runner.
