Safe escape medium shielding door capable of being opened smoothly
The invention is applicable to the technical field of shielding doors, and provides a safe escape medium shielding door smooth in door opening, which comprises a door frame, two fixed door leaves and two opening door leaves, and the two fixed door leaves are fixedly connected to two ends in the door frame respectively. According to the safe escape medium shielding door capable of being opened smoothly, by arranging the slidable linkage rack, when the shielding door is in a normal operation state, the linkage rack is meshed with the gear in the door frame, when accidents such as power failure occur, people can pull out the fixing plug, and at the moment, the limiting column does not limit the two clamping blocks any more; the clamping block is rebounded to the interior of the linkage rack under the action of the spring, the clamping block does not limit the linkage rack any more, the linkage rack falls down, the linkage rack and the gear are not meshed any more, the linkage rack is not limited any more, and at the moment, people can manually push the two opening door leaves outwards and escape from the interior of the automobile without being trapped; and therefore, the practicability of the shielding door is improved.
本发明适用于屏蔽门技术领域，提供了一种开门平滑的安全逃生媒介屏蔽门，包括门框、两个固定门扇和两个开启门扇，两个所述固定门扇分别固定连接于所述门框内部的两端。该开门平滑的安全逃生媒介屏蔽门，通过设置可滑动的联动齿条，在屏蔽门正常运行的状态下，联动齿条与门框上门框内的齿轮相互啮合，而在遇到停电等事故时，人们可将固定塞拔出，此时限位柱不再对两个卡块进行限位，在弹簧的作用下卡块被弹回联动齿条的内部，卡块就不再对联动齿条进行限位，联动齿条就会下坠，使得联动齿条与齿轮不再相互啮合，也就不再对联动齿条进行限位，此时人们即可手动将两个开启门扇向外推开并从车内逃离，不会被困住，从而提高了该屏蔽门的实用性。
