The invention relates to an anti-falling unit suitable for the elevator. The unit includes a first gear, a second gear, a trolley wheel, a triggering unit, a connecting rod, an elastic component and a supporting shaft. The guide rail is arranged between the first gear and the trolley wheel, the first gear engages with the gear surface of the guide rail, the trolley wheel rolls on the smooth surface of the guide rail, the connecting rod make the second gear revolve around the axis of the first gear and engage with the first gear, the connecting rod is provided with a triggering bore pluggably matting with the triggering end, when the triggering end withdraw from the triggering bore, the elastic force makes the second gear engage with the guide rail, at this moment, the mechanism has zero freedom degree, the elevator can not move downward or fall so as to achieve the anti-falling function of the elevator. <Figure 1> |
