The invention discloses a landing gear actuator control lock which comprises a shell with an axial through hole. A first nozzle is mounted at the left end of the shell, a third nozzle is mounted at the right end of the shell, the first nozzle is communicated with a first rod cavity of an actuator, the third nozzle is communicated with a second rod cavity of the actuator, an opening and closing structure is mounted in the axial through hole of the shell and used for opening or closing oil circuits of the first rod cavity and the second rod cavity of the actuator, a first thermal safety valve and a second thermal safety valve are mounted in the axial through hole of the shell, the first thermal safety valve is used for controlling excessive pressure due to excessive temperature and starting pressure release when the first rod cavity of the actuator is locked, and the second thermal safety valve is used for controlling excessive pressure due to excessive temperature and starting pressure release when the second rod cavity of the actuator is locked. Design complexity of a hydraulic system is reduced, the weight of the system is reduced, space is saved, and reliability and safety of the system and a mechanism are improved.
