The invention discloses a locking and unlocking device suitable for a space-based two-dimensional turntable, which comprises a space-based two-dimensional turntable bottom plate, a U-shaped frame and a two-dimensional turntable inner frame, and is characterized in that the U-shaped frame is mounted in the middle of the top surface of the space-based two-dimensional turntable bottom plate through a rotating shaft and can rotate along the rotating shaft; the two ends of the two-dimensional rotary table inner frame are installed in the U-shaped frame through pitch shafts respectively and can rotate along the pitch shafts. The two sides of the bottom of the U-shaped frame are locked through direction locking assemblies respectively, and the direction locking assemblies are installed on a space-based two-dimensional rotary table bottom plate. The outer side of the two-dimensional rotary table inner frame is locked through a pin puller, and the pin puller is installed at the top end of the U-shaped frame. The space-based two-dimensional tracking rotary table locking device meets the application requirement that a space-based two-dimensional tracking rotary table needs to be locked in the launching process, and has the advantages of being reliable in locking, simple in unlocking movement, capable of improving the rigidity of the whole rotary table and good in adaptability to the space mechanical environment and the temperature environment for a locking assembly of a pitching and azimuth mechanism of the two-dimensional rotary table.
