The invention relates to the technical field of shielding doors, in particular to a rail shielding door assembly with a two-stage lock structure, which comprises a first grouping lead screw, a second grouping lead screw, a lead screw barrel, a shielding door plate, a capacitance touch panel, a cavity gas layer and a negative pressure adsorption hole, a secondary lock structure is arranged between the first grouped screw rod and the second grouped screw rod and can control and switch two states of synchronous rotation and independent rotation of the first grouped screw rod and the second grouped screw rod; according to the rail shielding door assembly with the two-stage lock structure, when a person is clamped between the inner side of the shielding door and a subway, rescue can be achieved only by touching the capacitive touch panel through skin, compared with a mechanism needing to be pressed for unlocking in the prior art, the situation that the trapped person inclines forwards towards a subway carriage due to counter-acting force during pressing can be avoided, and the safety of the subway is improved. And the safety performance is higher.
本发明涉及屏蔽门技术领域,具体为一种带有二级锁结构的轨道屏蔽门组件,包括第一分组丝杆、第二分组丝杆、丝杆螺套、屏蔽门板、电容触摸面板、空腔气层和负压吸附孔,所述第一分组丝杆与所述第二分组丝杆同轴线轴端相对设置,所述第一分组丝杆与所述第二分组丝杆之间设置有二级锁结构,所述二级锁结构能够控制切换第一分组丝杆与第二分组丝杆同步旋转和单独旋转两种状态;本发明带有二级锁结构的轨道屏蔽门组件,在有人员卡在屏蔽门内侧与地铁之间时,仅通过皮肤触摸电容触摸面板便能够实现施救,相对于现有技术中需要按压解锁的机构,能够避免被困人员在按压时,受到反作用力而向地铁车厢前倾,具有更高的安全性能。
