The invention discloses a fireproof safe passage conversion indicator lamp which comprises a door arranged in a wall, a key shaft is rotatably connected in the door, a key hole into which a key can beinserted is formed in the key shaft, and a first spring cavity located on the upper side of the key hole is formed in the door. A jacking rod extending into the key shaft is slidably connected into the first spring cavity, and the lower side of the jacking rod makes contact with a contact rod slidably connected into the key hole and the first spring cavity. Compared with a traditional passage indicating lamp, the fireproof safe passage conversion indicator lamp has the advantages that firstly, indication can be changed through the locking condition of a door, secondly, when a fire occurs, theair cylinder is started to unlock the door, the indicator lamp is converted into the passage indicator lamp, and finally, the door can be automatically opened, so that evacuation of personnel is facilitated, and the safety is greatly improved.
本发明公开的一种防火式安全通行转换指示灯，包括设于墙壁内的门，所述门内转动连接有钥匙轴，所述钥匙轴内设有钥匙能插入的钥匙孔，所述门内设有位于所述钥匙孔上侧的第一弹簧腔，所述第一弹簧腔内滑动连接有伸入所述钥匙轴内的顶压杆，所述顶压杆下侧接触有滑动连接于所述钥匙孔与所述第一弹簧腔内的接触杆，本发明相比于传统的通行指示灯，首先，其能通过门的上锁情况来改变指示，其次，本发明能在发生火灾时，启动气缸来给门开锁，并转换指示灯为通行指示灯，最后还能自动打开门从而方便人员的撤离，极大的增加了安全性。
