The invention relates to the technical field of passenger train sliding plug doors, and discloses an inflatable sealed passenger train sliding plug door which comprises a base frame and a train door, and a driving mechanism is arranged on the base frame and used for driving the train door to move so as to open and close the door on the base frame; an inflatable sealing strip is arranged on the base frame and used for inflating and sealing a gap generated between the vehicle door and the base frame when the vehicle door is closed, an inflator pump is arranged on the inflatable sealing strip, and an air outlet is formed in the inflator pump; an air supply mechanism is further arranged on the base frame and used for driving the driving mechanism to operate and inflating and deflating the inflatable sealing strip through an inflator pump; the inflator pump is provided with a control mechanism and a locking mechanism which are used for automatically stopping inflation when inflation in the inflation sealing strip is completed. According to the sliding plug door for the inflatable sealing type passenger train, during inflation sealing, the inflation amount of the sealing strip can be automatically controlled, so that the expansion degree of the sealing strip is close to the most appropriate expansion amount under the influence of comprehensive factors when the train door and a train body are sealed as much as possible.
本发明涉及铁路客车塞拉门技术领域,且公开了一种用于充气密封式铁路客车塞拉门,包括基架和车门,基架上设置有驱动机构用于驱动车门位移以在基架上开关门;基架上设置有充气密封条用于充气密封车门在关门时与基架间产生的缝隙,充气密封条上设置有充气筒,充气筒上设置有出气口;基架上还设置有供气机构用于带动驱动机构运行以及通过充气筒向充气密封条内充气和放气;充气筒上设置有控制机构和锁定机构用于在充气密封条内充气完毕时自动停止充气;该用于充气密封式铁路客车塞拉门,在充气密封时,可自动控制向密封条内充气量,以使得密封条的膨胀程度尽量接近车门与车体在密封时所受综合因素影响下最适宜的膨胀量。
