Description

A kind of high-speed bicycle

The utility model relates to a kind of bicycle, specifically a kind of high-speed bicycle.

The history in existing more than 100 year of human invention bicycle, from the unicycle to the bicycle, from the pre-large post-small two-wheel two-wheel equal to front and back, from hard do not have tire wheel rim to air-inflation tyre, through countless inventors' effort, light, quick, attractive in appearance, the practical form that bicycle is developed into sell on the today of the market.Although the mankind have now had the multiple vehicle such as aviation, navigation, train, automobile, motor bike, but because many advantages such as bicycle is convenient, practical, inexpensive, safe, so far make bicycle in China and many in the world countries, remain the vehicle that people generally use.But also do not have so far a kind of desirable laborsaving, make things convenient for bicycle efficiently.

The purpose of this utility model provides a kind of modern design, and is simple in structure, laborsaving, make things convenient for bicycle efficiently.

Order of the present utility model is realized by following technical scheme.

The utility model is by the vehicle frame of spider, front fork, back vent, and wheel and transmission device are formed, and it is characterized in that:

There is a vehicle seat beam barrel that fuses with the spider end a, back vent upper end, and vehicle seat is screwed in the vehicle seat beam barrel by screw thread;

B, described transmission device comprise chain wheel, flywheel, chain and foot-operated, a pair of chain wheel is connected in both sides, spider bottom by bearing pin, a pair of flywheel is connected in two prong portions of back vent by bearing pin, chain wheel and flywheel are connected in one by a chain, a pair of foot-operated being loaded on respectively on the web of the upper and lower symmetry of two chain wheels.

In the time of by bike, the people steps on the foot-operated chain wheel that drives makes it drive chain and flywheel, drives wheel again and rotates rapidly, thereby overall height speed is exercised.Vehicle seat can be transferred to suitable height by rotation when the cyclist goes up a slope to pedal, make it laborsaving.

The utility model has the advantages that novel in design, simple in structure, laborsaving, quick, easy to use.

Fig. 1 is the utility model structural representation.

Fig. 2 is the oil bottle structural representation.

By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.

Embodiment 1:

(referring to Fig. 1,2) adorns a vehicle seat beam barrel 4 that fuses with the spider end in the back vent of vehicle frame 1 upper end, the vehicle seat 13 of bottom band screw rod is screwed in the vehicle seat beam barrel 4 by screw thread.The chain wheel 5 that with a pair of diameter is 36cm is loaded on both sides, spider bottom by bearing pin 9, and a pair of diameter is that the flywheel 6 of 8cm is loaded on two prong portions of back vent by bearing pin 9, with chain 7 chain wheel 5 and flywheel 6 is connected in one.Again a pair of riding formed rotating mechanism 3 on the web that is loaded on the upper and lower symmetry of two chain wheels respectively, to on its mouthful oil impregnate pipe 11 be housed, the a pair of oil bottle 10 of tip embedding folder hairbrush 12 is inverted in respectively on the chain 7, be fixed on the back vent, hairbrush is covered on the chain 7, during chain movement, the oil in the oil bottle 10 is oozed out by the oil impregnate pipe polishes it lubricated by hairbrush.
