Abstract
The utility model relates to a man-power bicycle, which comprises a bicycle body with a drive mechanism which uses ratchet mechanisms arranged at both ends of a rear wheel axle of the bicycle, wherein, ratchets of the ratchet mechanisms are respectively engaged with an arc-shaped rack which is respectively connected with one end of a connecting rod, wherein, the other end of which is extended to the crank position arranged on a middle axle of the bicycle and is movably cooperated and combined with the crank; the position of each connecting rod close to the arc-shaped rack is combined with a rear frame of the bicycle through a hinge axle. Due to the adoption of the structural characteristics, the utility model has the advantages of chain omitting and avoidance of chain falling and trouser edges and labor saving at the time riding.
Description
The utility model relates to a kind of bicycle and man.
The type of drive of known bicycle and man mainly is that the tortuous handle of roller is made circular movement, drives bicycle rear by driving chain and rotates.The existing deficiency of this type of drive have following some: one because the wheel disc crank makes circular movement, the brachium of crank be subjected to the restriction of distance between bicycle middle shaft and the ground and can not do long, make and comparatively require great effort when riding; Its two: owing to adopt chain-driving, easily produce loose chain, fall chain, and when riding, easily pollute trouser legs.
The purpose of this utility model provides a kind of bicycle and man with regard to being at above-mentioned existing in prior technology deficiency.
The purpose of this utility model can realize by following technical measures:
The utility model comprises the bicycle body that has driver train, and described driver train is the ratchet device that is separately positioned on the bicycle rear shaft two ends, and the ratchet in the described ratchet device is meshed with an arc-shaped rack respectively; Described arc-shaped rack is connected with an end of a connecting rod respectively, and the other end of described connecting rod extends to the crank position place that is arranged on the bicycle middle shaft place, and combines with described crank running-fit; Described connecting rod combines with rear bicycle frame by hinge near the arc-shaped rack place.
Described ratchet device is made up of unilateral bearing and the gear that is sleeved on the described unilateral bearing, or adopts bicycle freewheel.
Advantage of the present utility model just is to be respectively arranged with a ratchet device at the bicycle rear shaft two ends, and the ratchet in the described ratchet device is meshed with an arc-shaped rack respectively; And arc-shaped rack is connected with an end of a connecting rod, make and when riding, need only ride the crank left and right sides up-and-down movement that is arranged on the bicycle middle shaft place, can reach and drive the purpose that bicycle moves ahead.Owing to adopt connecting rod that arc-shaped rack is connected with crank, thereby save the chain of standard bicycle, avoided chain, polluted trouser legs, combine with rear bicycle frame by hinge near the arc-shaped rack place at described connecting rod simultaneously, thereby increased power arm, make when riding more laborsaving.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a three-dimensional schematic views of the present utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises the bicycle body that has driver train, and described driver train is the ratchet device that is separately positioned on bicycle rear shaft 1 two ends, and described ratchet device is made up of unilateral bearing and the gear that is sleeved on the described unilateral bearing.Ratchet 2 in the ratchet device is meshed with an arc-shaped rack 3 respectively; Arc-shaped rack 3 is connected with an end of a connecting rod 4 respectively, and the other end of connecting rod 4 extends to crank 5 positions that are arranged on the bicycle middle shaft place, and combines with crank 5 running-fits; Connecting rod 4 combines with rear bicycle frame 7 by hinge 6 near arc-shaped rack 3 places.
Claims (3)
