Abstract
The utility model relates to a labor-saving bicycle, which comprises a frame, a handle, wheels, pedals, a middle axle, a rear axle, a middle sprocket, a rear sprocket and a chain and is characterizedin that an accelerating pulley is arranged between the middle axle and the rear axle, the accelerating pulley is connected with the rear sprocket through the chain and the accelerating pulley is connected with the middle sprocket through a chain or teeth. Since the accelerating pulley is arranged between the middle axle and the rear axle, the utility model has the advantages that the point of force of the pedals can be reduced, the pedaling force of the feet is increased and thereby the goal of saving labor is obtained.
Description
Technical field
The utility model relates to technical field of bicycles, particularly a kind of labour-saving bicycle.
Background technology
Present bicycle mainly contains two kinds of common car and derailleurs, and it comprises vehicle frame, handlebar, wheel, stretcher, axletree, sprocket wheel and chain, and its shortcoming is relatively to require great effort when fast running.
Summary of the invention
The purpose of this utility model provides a kind of labour-saving labour-saving bicycle that compares when fast running.
The utility model is to realize like this, it comprises vehicle frame, handlebar, wheel, stretcher, axis, rear axle, middle sprocket, back sprocket wheel and chain, it is characterized in that between axis and rear axle, being provided with accelerating pulley, accelerating pulley is connected by chain with the back sprocket wheel, and accelerating pulley links or toe joint with middle sprocket.
The utility model can dwindle the force of stretcher owing to be provided with accelerating pulley between axis and rear axle, increases the power of pedaling of pin, reaches the labour-saving purpose.
