step one, opening a door;
in the initial state, the door frame (13) is closed, when the button (36) is stepped by feet, the button (36) drives the second piston rod (35) and the second piston (34) to move downwards, the second piston (34) drives the third piston (38) and the third piston rod (39) to move downwards through hydraulic oil, the diameter of the upper cylinder body (32) is larger than that of the lower cylinder body (33), so that the descending distance of the second piston rod (35) is smaller than that of the third piston rod (39), the third piston rod (39) drives the second connecting rod (23) to rotate downwards through the first connecting rod (22), the rack (24) is pressed downwards through the second connecting rod (23), on one hand, the rack (24) drives the first piston rod (48) to move downwards, the hydraulic oil on the lower side of the first piston (45) in the inner cylinder body (42) flows through the one-way valve (46) and rapidly enters the inner cylinder body (42) on the upper side of the first piston (45), the spring (47) is compressed;
on the other hand, the rack (24) drives the first gear (28) to rotate, the first gear (28) transmits power to the second rotating shaft (27), the second gear (29), the third gear (212), the third rotating shaft (211), the worm (213), the worm wheel (217), the fourth rotating shaft (216), the driving bevel gear (218) and the driven bevel gear (219) in sequence, and the driven bevel gear (219) drives the door frame (13) to rotate through the first rotating shaft (14), so that the door frame (13) is opened;
step two, closing the door in a delayed manner;
the button (36) is loosened, the spring (47) upsprings the first piston (45), because the hydraulic oil on the upper side of the first piston (45) cannot flow through the one-way valve (46) to reach the lower side of the first piston (45), the hydraulic oil on the upper side of the first piston (45) can only enter the outer cylinder (43) through the oil hole (44) on the top of the inner cylinder (42) and then enter the lower side of the first piston (45) through the oil hole (44) on the bottom of the inner cylinder (42), because the aperture of the oil hole (44) is small, the flow rate of the hydraulic oil is slow, the upward movement speed of the first piston (45) is low, the upward movement of the first piston (45) drives the first piston rod (48) and the rack (24) to move upwards, on one hand, the rack (24) drives the second connecting rod (23) to rotate reversely, and the second connecting rod (23) sequentially transfers power to the first connecting rod (22), the third piston rod (39) and the third piston (38), the third piston (38) drives the second piston (34) and the second piston rod (35) to move upwards through hydraulic oil, so that the button (36) is reset to wait for the next stepping;
on the other hand, the rack (24) drives the first gear (28) to rotate reversely, the first gear (28) transmits power to the second rotating shaft (27), the second gear (29), the third gear (212), the third rotating shaft (211), the worm (213), the worm wheel (217), the fourth rotating shaft (216), the driving bevel gear (218) and the driven bevel gear (219) in sequence, and the driven bevel gear (219) drives the door frame (13) to rotate reversely through the first rotating shaft (14), so that the door frame (13) is closed slowly.
