Abstract

The invention provides a labor-saving bicycle, and belongs to the technical field of bicycles. The problem of poor stability of an existing bicycle structure is solved. The labor-saving bicycle comprises a bicycle frame and driving wheels, the side part of the bicycle frame is connected with a crankshaft disc which is vertically arranged, and the side part of the crankshaft disc is connected withpedals; the labor-saving bicycle also comprises a guide rod, a guide sleeve, a drive rod, a transmission rod and a transmission shaft I, the guide rod is vertically fixed on the bicycle frame above the crankshaft disc, the guide sleeve sleeves the outer side of the guide rod, one end of the drive rod is hinged to the eccentric position of the side part of the crankshaft disc, the other end of thedrive rod is hinged to the outer side of the guide sleeve, one end of the transmission rod is hinged to the outer side of the guide sleeve, the other end of the transmission rod is sleeved on the outer side of the transmission shaft I and can drive the transmission shaft I to rotate in the circumferential direction, a one-way transmission mechanism is connected between the transmission rod and thetransmission shaft I or the transmission shaft I and the drive wheel, and the one-way transmission mechanism can enable the transmission rod to drive the drive wheel to rotate in one direction. The labor-saving bicycle has the advantage of good structural stability.

Description

technical field [0001] The invention belongs to the technical field of bicycles and relates to a labor-saving bicycle. Background technique [0002] Because of its economy, convenience, flexibility, pollution-free and docking freedom, bicycles begin to receive people's attention constantly, and bicycles will inevitably become an indispensable means of transportation in people's daily life. Yet present bicycle only cooperates simple sprocket chain structure to drive wheel forward by traditional foot pedal, once run into the road condition that needs bigger driving force such as steep slope, will cause bigger inconvenience to people's travel. [0003] For this reason, people have designed a kind of double crank connecting rod reciprocating bicycle and have applied for Chinese patent (its application number is: 201410733747.8; Its announcement number is: CN104527899B), this double crank connecting rod reciprocating bicycle comprises double crank connecting rod mechanism, the T...
