Provided is a seat frame structure capable of being turned. The technical scheme is that the seat frame structure capable of being turned comprises a limit plate, a sleeve, a limit plate support, a spring, a left connection plate, a right connection plate, a seat cushion framework and a backrest framework. The seat cushion framework comprises a bottom frame, a seat frame and a base. When the bottom frame rotates to form a certain angle with the horizontal direction, a locking block in the middle of the left connection plate or the right connection plate slides into a locking slot on the limit plate, and the bottom frame is locked in position. If the bottom frame rotates upwards continuously, the locking block on the left connection plate or the right connection plate can be separated from the locking slot, and the bottom frame can be turned downwards to the horizontal level. The seat frame structure is simple in operation, reliable in locking and good in stability.
