The invention relates to a mechanism for automatically opening a roller shutter door (20) in emergency, which comprises a roller (21) which is a hollow round roller and comprises at least one first positioning hole (211), and the first positioning hole is arranged at one end of the roller; the diameter of the rotating shaft (22) is smaller than that of the roller (21), the rotating shaft can rotate along with the roller (21), and two rotating ends (222) are formed by protruding from the two ends of the roller; one end (241) of the spring (24) is fixed on the rotating shaft (22), and the other end (242) of the spring (24) is fixed on the inner surface of the roller (21); when the rotating shaft (22) rotates relative to the roller (21) in the opposite direction of the roller shutter door body, the spring (24) rotates to generate elastic stored energy of the spring (24). The elastic energy storage fixing unit (25) is arranged at the rotating end (222) of the rotating shaft (22), and a first positioning hole (211) used for fixing elastic energy storage is formed in the roller (21); and the starter is started to release the elastic stored energy, so that the automatic opening efficiency of the roller shutter door is ensured.
本申请涉及一种紧急情况下自动打开卷帘门(20)的机构，包括：滚筒(21)，为空心圆滚筒，包括至少一个第一定位孔(211)，第一定位孔设置在滚筒的一端；旋转轴(22)，旋转轴的直径小于滚筒(21)的直径，可随滚筒(21)转动，并从滚筒的两端突出形成两个旋转端(222)；至少一个弹簧(24)，一端(241)固定在旋转轴(22)上，另一端(242)固定在滚筒(21)的内表面；当旋转轴(22)相对于滚筒(21)沿卷帘门体的相反方向相对旋转时，弹簧(24)回旋产生弹簧(24)的弹性蓄能；弹性蓄能固定单元(25)，设置在旋转轴(22)的旋转端(222)上，滚筒(21)上设有用于固定弹性蓄能的第一定位孔(211)；启动器启动，释放弹性蓄能，从而保证卷帘门自动开启的效率。
