The invention relates to a design method for the anti-falling elevator. The method mainly includes providing the anti-falling unit with a first gear, a second gear, a trolley wheel, a connecting rod and an elastic component; arranging the guide rail between the first gear and the trolley wheel; arranging for the first gear to engage with the gear surface of the guide rail; arranging for the trolley wheel to roll on the smooth surface of the guide rail, arranging for the connecting rod to make the second gear revolve around the axis of the first gear and engage with the first gear; providing the connecting rod with a triggering bore pluggably matting with the triggering end; when the triggering end withdraw from the triggering bore, arranging for the elastic force to make the second gear engage with the guide rail, at this moment, the mechanism has zero freedom degree, the elevator can not move downward so as to achieve the anti-falling function of the elevator. <Figure 1> |
