The invention discloses a connecting rod type self-locking mechanism for a boat frame, the self-locking mechanism is arranged on a boat frame, the self-locking mechanism is connected with a shaft body arranged in the center of two sides of a movable pulley, the self-locking mechanism comprises a connecting rod I, a connecting rod II and a connecting rod III, the connecting rod I and the connecting rod II are L-shaped, an arc-shaped notch is arranged at the intersection of the long side and the short side of the connecting rod I. The middle of the long side of the connecting rod I and the boat frame are hinged to a point A. The top of the long side of the connecting rod I and the top of the long side of the connecting rod II are hinged to a point B. The long side of the connecting rod II and the connecting rod III are both arc-shaped, the inner arc of the connecting rod II is attached to the outer arc of the connecting rod III, and the short side of the connecting rod II and the left end of the connecting rod III are hinged to a point C. The right end of the connecting rod III is hinged to the boat frame at a point D. A threading eye plate is arranged at the bottom of the long side of the connecting rod II, one end of a control rope is connected with a hanging ring on the boat frame, and the other end of the control rope sequentially penetrates through a pulley on the hull structure, the threading eye plate and a pulley at the bottom of the boat frame and is finally connected with a remote control locking protection device.
