Description

Technical Field

[0001] The present invention relates to the technical field of railway station facilities, and particularly relates to a one-way door. Background Art

[0002] The one-way door, also known as a one-way access door, is usually arranged at railway stations and bus stations to facilitate passengers inside the station to exit unidirectionally. Among the existing one-way doors, the comb-shaped one-way access door is the most common one. During its use, there are the following defects: First, people on both sides of the one-way door can pass dangerous goods to each other, posing a safety hazard during the use of the station; Second, when the comb-shaped one-way access door is in use, it connects the inside and outside of the station. When the air conditioner is turned on in summer and winter, it reduces the heating or cooling effect of the air conditioner, resulting in a large waste of energy consumption. Summary of the Invention

[0003] The purpose of the present invention is to provide a one-way door, which has the effects of one-way passage, preventing people on both sides from passing items, and reducing the waste of air-conditioning energy consumption inside the station when in use.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A one-way door includes a frame, the frame is provided with a pedestrian passage, a return passage, a plurality of door leaves movably arranged on the frame, and a driving mechanism. The side wall of the pedestrian passage is provided with two connecting passages communicating with the return passage, and the driving mechanism is used to drive the door leaves to move cyclically in the pedestrian passage and the return passage.

[0005] By adopting the above technical solutions, when the one-way door works, the driving mechanism drives the door leaves to move in the pedestrian passage and the return passage. After a pedestrian enters the pedestrian passage, they walk forward following the door leaf. When the door leaf moves to the connecting passage on the side wall of the pedestrian passage, the door leaf passes through the connecting passage and enters the return passage, and the pedestrian continues to walk forward and exits the pedestrian passage. During the working process of the one-way door, there are a plurality of door leaves, so that there is always at least one door leaf in the pedestrian passage to prevent pedestrians from passing through the pedestrian passage in the reverse direction, realizing one-way passage.

[0006] When the one-way door is installed in the station, the door leaves in the pedestrian passage of the one-way door can play a blocking role, preventing people on both sides of the door leaf from passing items to each other, and having good safety performance. When the air conditioner in the station heats or cools, the blocking of the door leaf can reduce the air convection on both sides of the one-way door, which is beneficial to maintaining the heating effect or cooling effect inside the station and reducing the waste of energy consumption.

[0007] The further setting of the present invention is that: the driving mechanism includes a plurality of independent driving units.

[0008] By adopting the above technical solution, the driving mechanism includes several independent driving units, each of which drives the door leaf to move a certain distance, so as to flexibly adjust the position of the door leaf when the one-way door fails or a pedestrian is stuck.

When a recessed hole 1 is provided on the toggle part 1, a plurality of driven parts 1 are fixed on the door leaf, and after the driven part 1 is embedded in the recessed hole 1, the movement of the chain drives the toggle part 1 and the driven part 1 to move, thereby driving the door leaf to move.

[0011] When another driven part 1 on the door leaf is embedded in a recessed hole 1 of a toggle part 1 in a next driving unit, the next driving unit drives the door leaf to continue moving. During the movement of the door leaf, one of the driven parts 1 is disengaged from a recessed hole 1 of a toggle part 1 in a previous driving unit.

[0012] The present invention is further configured as follows: the driving unit includes two transmission wheels rotatably arranged on the frame, a transmission belt sleeved on the two transmission wheels, and a driving motor 2 for driving the transmission wheels to rotate forward or reversely, a driven part 2 is fixed on the door leaf, a toggle part 2 is fixed on the transmission belt, the toggle part 2 is provided with a recessed hole 3 for the driven part 2 to be embedded in, or the driven part 2 is provided with a recessed hole 4 for the toggle part 2 to be embedded in, or the toggle part 2 is used to abut against the side wall of the driven part 2 to drive the driven part 2 to move.

[0013] By adopting the above technical solution, the second driving motor drives the transmission wheel to rotate, the transmission wheel drives the transmission belt to move, the second driving part on the transmission belt drives the second driven part to move, and the second driven part drives the door leaf to move.

One end of the pedestrian passage 11 is an entrance, and the other end is an exit. The side walls at the entrance and exit of the pedestrian passage 11 are both provided with connecting passages 13, and the connecting passage 13 connects the pedestrian passage 11 with the return passage 12. The width of the connecting passage 13 is greater than the thickness of the door leaf 2, so that the door leaf 2 can pass through the connecting passage 13. A slide groove 14 is arranged on the frame 1, and the door leaf 2 includes a door body 21 and a slide seat 22 fixed on the door body 21, and the slide seat 22 is embedded in the slide groove 14.
