Abstract

The invention relates to a civil air defense protective door locking device. The civil air defense protective door locking device comprises a push rod 1, a connection rod 2, a rotary plate 3, a rotary plate driving mechanism, at least one locking pin 5 and a corresponding pin seat 51, wherein the push rod 1 is arranged close to one edge of a door frame; the locking pin 5 is arranged on one side, close to the door frame, of the push rod 1; the pin seat 51 is mounted in the position corresponding to the position of the locking pin 5 of the door frame; one end of the connection rod 2 is connected with the push rod 1; the other end of the connection rod 2 is connected with the rotary plate 3; the rotary plate driving mechanism is connected with the rotary plate 3; the rotary plate 3 is capable of rotating under the driving of the rotary plate driving mechanism; the rotary plate 3 rotates and drives the connection rod 2 to axially move, so that the locking pin 5 is inserted into or removed out of the corresponding pin seat 51. With the adoption of gear transmission, the civil air defense protective door locking device is high in transmission efficiency. Compared with the adoption of worm and gear transmission in an existing civil air defense protective door locking device, the civil air defense protective door locking device has the advantages of simple structure, low cost and the like.
