Abstract

The invention discloses a combination drive device of a pulley block and a lever and a bicycle, which comprises two high brackets and two low brackets arranged side by side; a power input shaft and a winch are arranged on the low bracket; fixed pulleys, Crankshaft, and lever; one end of the lever is hinged with the high bracket as a fulcrum, and the other end is equipped with a movable pulley; a chute is arranged between the two ends of the lever; the end of the noose is fixed on the winch, and the other end of the noose is wound around the fixed pulley and After the movable pulley, it is fixed on any point vertically downward of the axis of the fixed pulley; the power input shaft winches the noose by driving the winch, and the noose pulls the fixed pulley and the movable pulley so as to pull the lever to pry the crankshaft to rotate and output power. The bicycle of the present invention comprises a pulley block and a lever combined driving device, which can save labor and be fast.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a combination drive device of a pulley block and a lever and a bicycle. Background technique [0002] The use of levers and pulley blocks is very common. Although they are common, especially pulley blocks, they are mostly used for lifting or dragging heavy objects, which saves effort. However, the use of a pulley block and a lever can superimpose the increased transmission ratio to increase step by step, and the mechanical drive device that can continuously output rotating work is extremely rare. The present invention is exactly a kind of pulley block, lever combination, to strengthen the mechanical driving device of rotating torsion moment, is by the external power input shaft, and the crank arm, winch wheel, noose, fixed pulley that are parallel and vertical, and fixed at both ends of the power input shaft , movable pulley, lever, crankshaft, etc. constitute t...
