一种为平时关闭状态，有人走动时，要推动门开启，人走过后在闭门器作用下自动关闭，有恢复到关闭状态，称之为活动式防火卷帘门。

One is usually closed. When someone walks around, the door should be pushed to open. After walking, the door will automatically close under the action of the door closer. If it returns to the closed state, it is called a movable fire rolling shutter door.
