The present invention relates to a solenoid-type explosion-proof elevator door interlock, which locks an elevator door with an external lead power terminal and a solenoid formed inside an explosion-proof case. A timer switch is formed on a front end of the solenoid, and when an elevator is stopped and a solenoid driving signal is applied to the external lead power terminal, the solenoid is driven only for a setting driving time of the timer switch. According to the present invention, a door interlock, that is a primary part for safety of the elevator in areas such as marine plants or warships where reliability is required, is developed to have an explosion-proof structure, thereby providing the solenoid-type explosion-proof elevator door interlock having reliable safety with respect to a fire or explosion. |
