The baby carriage seat frame structure comprises two rotary connecting bases and aseat frame detachably connected to the two rotary connecting bases. Bayonet locks for locking the rotary connecting bases are arranged on the rotary connecting bases; mounting bases detachably connected to the rotary connecting bases are arranged on two sides of the seat frame. Seat locking assemblies are arranged between the mounting bases and the rotary connecting bases; a backrest rod is arranged between the two mounting bases in a spanning manner; rotating seats capable of enabling the backrest rod to rotate relative to the mounting bases are arranged between the end parts of the backrestrod and the mounting bases; backrest locking assemblies capable of locking the rotating seats are arranged between the rotating seats and the mounting bases; a backrest unlocking assembly for unlocking the backrest locking assemblies is arranged on the backrest rod, arc-shaped notches are formed in the rotating seats in the rotating direction of the rotating seats and used for avoiding the bayonetlocks so that the bayonet locks can slide in the arc-shaped notches when the rotating seats rotate, and guide inclined faces which enable the bayonet locks to be ejected out to unlock the rotary connecting bases are arranged at the ends of the arc-shaped notches.
