The vertical hinged door leaf 10 is located inside the outlet 12, a handle is not installed on the side, located on the outer side of the one-way door, of the vertical hinged door leaf 10, and passengers on the outer side of the one-way door outlet 12 are difficult to open the vertical hinged door leaf 10 from the outer side of the one-way door body 1.

Example 11: the one-way door with the closing door is different from the one-way door in embodiment 1 in that the closing door is a spring door, and the spring door is arranged at the inlet 11 and the outlet 12 of the one-way door body 1.

Example 12: a one-way door with a closing door, which is different from embodiment 1 in that, as shown in fig. 19, 20, 21 and 21, the one-way door comprises a frame, a main door 6 rotatably connected to the frame, a one-way device 64 for limiting the one-way rotation of the main door 6, a winding drum 19 rotatably arranged on the frame, and a sub-door 193 wound on the winding drum 19, wherein the frame is fixed with a mounting shaft 191, a first torsion spring 192 is mounted on the mounting shaft 191, one end of the first torsion spring 192 is fixed with the mounting shaft 191, and the other end is fixed with the winding drum 19. A slide rail is fixed on the frame, and a pulley 18 is connected on the slide rail in a sliding way. The main door 6 comprises a main shaft 61, three revolving door leaves 62 fixed to the main shaft 61. A driving crank 65 is fixed on the main shaft 61, a transmission connecting rod 66 is hinged on the driving crank 65, and the transmission connecting rod 66 is connected with the pulley 18. The sub-door 193 includes a plurality of door pieces hinged in sequence, and the sub-door 193 is fixed to the pulley 18. The elastic force of the first torsion spring 192 drives the winding drum 19 to wind the auxiliary door 193, and the pulley 18 is driven to move towards one end of the sliding rail.

The frame is also rotatably connected with a balance rotating shaft 201, a balance wheel 20 is fixed on the balance rotating shaft 201, and the balance wheel 20 and the winding drum 19 are distributed on two sides of the pulley 18. The balance wheel 20 is wound with a balance belt 202, one end of the balance belt 202 is fixed with the balance wheel 20, and the other end is fixed with the pulley 18. The balance rotating shaft 201 is sleeved with a second torsion spring 203, one end of the second torsion spring 203 is fixed with the balance rotating shaft 201, and the other end of the second torsion spring 203 is fixed with the rack. The elastic force of the second torsion spring 203 drives the balance rotating shaft 201 and the balance wheel 20 to rotate, so as to drive the pulley 18 to move towards the other end of the sliding rail.

When the passenger pushes the main door 6 to rotate, the main door 6 drives the pulley 18 to reciprocate through the main crank 81 and the transmission connecting rod 66. When the sliding vehicle 18 moves towards one end of the sliding rail and approaches the winding drum 19 when the rotating door leaf 62 of the main door 6 approaches the auxiliary door 193, the elastic force of the first torsion spring 192 drives the winding drum 19 to rotate to wind the auxiliary door 193, so that the door leaf of the main door 6 passes through the auxiliary door 193. The main door 6 continues to rotate and the trolley 18 moves towards the other end of the track and away from the drum 19, the trolley 18 driving the secondary door 193 to unfold and close to the main axis 61 of the main door 6, preventing the passenger from passing the one-way door in the opposite direction with the main door 6.
