Description

Acceleration bicycle

Technical field:

The utility model relates to a kind of acceleration bicycle.

Background technology:

Bicycle mostly is battery-driven car or traditional chain bicycle on the present domestic bicycle market.Though can both play the bicycle effect, can't realize quickening and mechanicals efforts.

Summary of the invention:

The purpose of this utility model be a kind of not electricity consumption of on the left side of former bicycle pedal axis, rear axle, having set up big trochal disc, sprocket wheel, need not oil, can realize a kind of acceleration bicycle of acceleration effort, to overcome above-mentioned deficiency.

The purpose of this utility model is realized by following technical scheme:

A kind of acceleration bicycle, comprise: ratchet, stage clip, sour jujube key, big trochal disc, sprocket wheel, chain, be characterized in: on the pedal axis in bicycle left side ratchet is housed, stage clip, sour jujube key are housed on the ratchet, ratchet is equipped with big trochal disc on the outer ring, sprocket wheel is housed on the rear axle, connects big trochal disc, sprocket wheel by chain.

Adopt the utility model acceleration bicycle, can alleviate manpower, be a kind of not electricity consumption, need not oil, both environmental protection resources conservations can realize a kind of acceleration bicycle of acceleration effort again,

Description of drawings:

Fig. 1 is the structural representation of the utility model acceleration bicycle;

Below in conjunction with accompanying drawing the utility model is further described:

The specific embodiment:

Embodiment:

As shown in Figure 1, the utility model is made up of ratchet 1, stage clip 2, sour jujube key 3, big trochal disc 4, sprocket wheel 5, chain 6, on the pedal axis in bicycle left side ratchet 1 is housed, stage clip 2, sour jujube key 3 are housed on the ratchet 1, ratchet is equipped with big trochal disc 4 on 1 outer ring, sprocket wheel 5 is housed on the rear axle, connects big trochal disc 4, sprocket wheel 5 by chain 6.

During use, former bicycle continues pedal, and big trochal disc 4 together rotates and drive sprocket wheel 5 moves ahead bicycle, and sprocket wheel 5 rotates with bicycle rear axle the time, and is simple in structure, very easy to use flexibly.
