The invention belongs to the field of airplane structure design and provides a hook-shaped cabin door position limiting mechanism, which includes a pedestal (2) being connected to a door frame through a screw joint. A position limiting groove is formed in the middle of the pedestal (2). A tail part of a hook-shaped position limiting member (1) is connected to a cabin door through a screw joint. The head of the hook-shaped position limiting member (1) is connected to one end of the position limiting groove formed in the middle of the pedestal (2) through a pin joint through a flat-head shaft (7). A short arm of an L-shaped irregular-shaped shaft switch (4) passes through a side wall of the position limiting groove on the pedestal (2) and is stretched into the position limiting groove. A hook-shaped groove is arranged in the middle of a U-shaped position limiting push rod (3) in the direction opposite to an opening. The position limiting push rod (3) is connected to the other end of the position limiting groove on the pedestal (2) through a pin joint through the flat-head shaft (7) in the direction of being backside to the position limiting groove. The irregular-shaped shaft switch (4) is sleeved with a torsional spring (6) so that a long arm of the irregular-shaped shaft switch (4) is in a raised status under a normal state. The position limiting push rod (3) is sleeved with an irregular-shaped torsional spring (5) so that the position limiting push rod (3) is in a raised status under a normal state.
