Retractable launching box locking mechanism

The invention provides a retractable launching box locking mechanism which comprises a base mounted on a missile transporting and filling vehicle, and a turnover mechanism, a transmission mechanism, a sensing mechanism, a driving mechanism and a launching box positioning seat are mounted on the base; the sensing mechanism is used for sensing the state of the turnover mechanism and is electrically connected with the driving mechanism, the driving mechanism is in transmission connection with the transmission mechanism, and the transmission mechanism is in transmission connection with the turnover mechanism; the overturning mechanism comprises a spring bolt capable of overturning, and the spring bolt is matched with the launching box positioning seat to lock the launching box. The sensing mechanism senses and feeds back signals, the driving mechanism is remotely controlled to move, the transmission mechanism is used for transmission to control the turnover mechanism to turn over, a spring bolt can be accurately
