Abstract
A reciprocating-pedaling bicycle comprises a chassis, wheels, and a chain wheel. The chain wheel is provided on the middle axle of the chassis, and is connected with the flywheel of the rear wheel through a chain. The bicycle is characterized in that a connection block is equipped on the chassis; the end portions of a left and a right pedal levers are fixed at the connection block through a pedal shaft; a ratchet is respectively equipped on both ends of the middle axle of the chassis; and the pedal lever is connected with the ratchet through the combination of chain and spring or the combination of cord and spring to drive the ratchet to rotate. The reciprocating-pedaling bicycle has novel structure, and the efficiency of the bicycle is improved greatly by using the reciprocating pedaling to substitute original revolution pedaling, thereby achieving easy drying and saving labor.
Description
Technical field
The utility model relates to bicycle, especially a kind of reciprocal pedal-type bicycle.
Background technology
Existing bicycle structure comes from the bicycle at initial stage before 200 years, though its early stage bicycle has had many changes, it scrunches mode and drive configuration fails to have breakthrough always.Existing bicycle swinging is pedaled and is stepped on the formula drive configuration, and its single pedal is stepped on the not enough half cycle (upper-lower position all has the dead point) of effective exercise, and therefore, effect is not high.
Summary of the invention
The purpose of this utility model just provides a kind of novel structure, reciprocal pedal-type bicycle that effect is high.
Reciprocal pedal-type bicycle of the present utility model comprises vehicle frame, wheel, sprocket wheel, establish sprocket wheel on the vehicle frame axis, sprocket wheel links to each other with the back flying wheel by chain, be characterized in being provided with on the vehicle frame contiguous block, the end of left and right treadle is fixed on the contiguous block by the treadle axle, vehicle frame axis two ends are provided with ratchet respectively, and treadle links to each other with ratchet with spring with spring or rope by chain, and drive the ratchet rotation.
The principle of work of the reciprocal pedal-type bicycle of the utility model:
People ride when scrunching, and left and right sides treadle moves through rope or chain drives left and right sides ratchet respectively, and ratchet drives sprocket wheel through axis, and sprocket wheel finally advances bicycle by the chain drive bicycle rear, and afterwards, treadle is subjected to the traction action power self-return of spring.
Reciprocal pedal-type bicycle novel structure of the present utility model because type of drive is pedaled the formula of stepping on by original revolution and changed reciprocal pedal-type into, make its effect improve greatly, and it is easily laborsaving to ride.
