[0036] In some cases, the subway is delayed and the number of people waiting for the train in the station increases, but the traditional seats are not convenient to extend their length to serve more passengers. In this case, the subway staff can use the key to open the side door 2 on one side and rotate the crank 27. Driven by the first bevel gear 24 and the second bevel gear 25, the two groups of auxiliary seats 8 can be synchronously moved out of the main seat 1 to open. The structure is easy to operate. At the same time, the staff can quickly put down the front support feet 10 and the rear support feet 11, and use the latch to lock the second ear plate 7 between the sealing plate 9 and the front support feet 10 to make the supporting structure perpendicular to the auxiliary seats 8 to keep the device stable.

[0044] For reasons such as cleaning, adjusting facilities in the station, or avoiding affecting the flow of people, the seats on the platform level of the subway station sometimes need to be adjusted. Traditional seats are inconvenient to adjust, and the staff cannot quickly and effortlessly open the seat casters 22. In this device, the staff opens the corresponding side door 2, and then presses the pressure rod 19 up and down, so that the movable rod 18 in the jack 17 rises under the push of the oil, and then moves the movable plate 21 down until the bottom of the caster 22 is completely in contact with the ground. The process is relatively simple and convenient, allowing the staff to complete the operation effortlessly. When the caster 22 needs to be retracted, it is only necessary to open the return oil valve 20 to allow the oil in the jack 17 to return to its original position.

[0045] The working principle of a movable subway seat provided by the utility model is as follows:

[0046] Step 1: In some cases, the subway is delayed and the number of people waiting for the train in the station increases, but the traditional seats are not convenient to extend their length to serve more passengers. In this case, the subway staff can use the key to open the side door 2 on one side and rotate the crank 27. Driven by the first bevel gear 24 and the second bevel gear 25, the two sets of auxiliary seats 8 can be synchronously moved out of the main seat 1 to open. The structure is easy to operate. At the same time, the staff can quickly put down the front support legs 10 and the rear support legs 11, and use the latch to lock the second ear plate 7 between the sealing plate 9 and the front support legs 10 to make the supporting structure perpendicular to the auxiliary seats 8 and keep the device stable. When closing, the supporting structure can be retracted and the crank 27 can be reversed. This design is convenient for the staff to quickly retract the auxiliary seats 8 when there is a large flow of people during peak hours in the morning and evening to prevent congestion on the platform. When the flow of people is small, the auxiliary seats 8 are opened to provide a resting place for people in the station.

[0047] The second step: For reasons such as cleaning, adjusting facilities in the station, or avoiding affecting the flow of people, the seats on the subway platform sometimes need to be adjusted. Traditional seats are inconvenient to adjust, and the staff cannot quickly and effortlessly open the seat casters 22. In this device, the staff opens the corresponding side door 2, and then presses the pressure rod 19 up and down, so that the movable rod 18 in the jack 17 rises under the push of the oil, and then the movable plate 21 moves down until the bottom of the caster 22 is completely in contact with the ground. The process is relatively simple and convenient, allowing the staff to complete the operation effortlessly. When the caster 22 needs to be retracted, it is only necessary to open the return oil valve 20 to allow the oil in the jack 17 to return to its original position.
