The invention relates to the field of elevators and in particular relates to an anti-falling elevator. The invention discloses the anti-falling elevator. The anti-falling elevator mainly comprises a bracket fixedly connected with a lift car, a guide rail arranged along an elevator well and an anti-falling unit. The anti-falling elevator is characterized in that the anti-falling unit comprises a first gear, a second gear, a roller, a triggering unit, a connection rod, an elastic restoring part and a support shaft; the triggering unit is mounted on the bracket; the roller and the first gear are freely and rotationally mounted on the bracket by virtue of the support shaft; the guide rail is arranged between the first gear and the roller; the first gear is meshed with the toothed surface of the guide rail; the roller is in rolling fit with the smooth surface of the guide rail; the second gear rotates around the first gear and is meshed with the first gear by virtue of the connection rod; the connection rod is provided with a triggering hole in insertion fit with a triggering end of the triggering unit. When the triggering end is withdrawn from the triggering hole, the second gear is meshed with the guide rail by means of the elastic force of the elastic restoring part, the freedom degree of the mechanism at the moment is 0 and the elevator is incapable of running up and down, so that the falling of the elevator can be prevented.
