Disclosed is a lead screw engaged elevator. The lead screw engaged elevator is characterized in that the elevator is provided with a motor (1); the motor drives a lead screw I to rotate through a belt (2) and drives a reversing gear (3) so as to drive a lead screw II to rotate; the lead screw I and the lead screw II are engaged with threaded sleeves (5) on a car body (4) through rotation so as to lift the car body; the lead screws are fixed up and down through bearings (6); the upper portion of the car body is connected with a cable rope (7); the cable rope is connected with a balance weight (9) through a pulley (8). According to the lead screw engaged elevator, the lead screws and the threaded sleeves are engaged so that the car body can be controlled to lift, and the phenomenon that common elevators suddenly fall down due to breaking of cable ropes can be avoided.
