The invention discloses an elevator with a hidden type rescue hole, and relates to the technical field of elevators. The elevator comprises a car which is of a box body structure, wherein a groove is formed in the upper surface of the car; a rotary shaft is rotatably connected in the groove; a rotary block is fixedly connected to the peripheral side surface of the rotary shaft; the left side wall of the rotary block is fixedly connected to a rescue door; a concave hole is formed in the left side wall of the rescue door; an extrusion spring is fixedly connected in the concave hole; one end of the extrusion spring is fixedly connected to a wedge-shaped block; a rescue hole is formed in the upper surface of the car; and a blocking slot is formed in the left side wall of the rescue hole. The wedge-shaped block is arranged, and a rescue door is rotated, so that the wedge-shaped block is blocked into the blocking slot; the groove is equal to the rotary block in size, and the rescue hole is equal to the rescue door in size, so that passengers are prevented from opening the rescue door; and a button is arranged outside the car in a matched mode, so that a rescuer can press the button to extrude the wedge-shaped block through an extrusion rod for opening the rescue door to rescue.
