Description

Full-plastic bicycle

The utility model is a kind of vehicle during people live.

At present, bicycle has spreaded all over China town and country, be the indispensable vehicle in people's daily life, but the bicycle of bicycle 98 percent or more that uses now other all make by part by metallic material, these bicycle body's weight are big, corrosion-vulnerable is got rusty and is damaged, complex structure, cost is higher, maintenance difficult and seriously polluted, cause inconvenience for people's use, therefore develop a kind of Full-plastic bicycle is problem anxious to be solved both at home and abroad always.

The purpose of this utility model is exactly that a kind of band simple in structure, handsome in appearance, bent, spoke, rim axle skin are connected as a single entity, car body is light, cost is low in order to provide, pollution-free, laborsaving, use Full-plastic bicycle easy to maintenance.

The purpose of this utility model is achieved in that whole device is by saddle, the seat pipe, vehicle frame, back brake, flywheel, after pull out chain, chain, before pull out chain, the bent plate wheel disc, pedal, reflector plate, upright, cross handle, brake lever, the speed change handle, front fork, front brake, cover tire, the inner tube of a tyre, rim, the axle skin, valve, mudwing, the brake cable pipe, the speed change spool, clothes hanger, the bent band of wheel is formed, vehicle frame adopts the plastic hollow pipe of a compression molding to make, clothes hanger, pedal, crank wheel disk is connected on the vehicle frame with screw, wheel adopts sun wheel, adopt once molding formed rim, the axle skin, the bent band of wheel, three groups of bent being with and rim of six roots of sensation wheel, the axle skin connects together, the axle intracutaneous is installed two cover bearings, handlebar, the car fork adopts the hollow pipe of moulding to make.Handlebar has three kinds of patterns, and conventional shape is made swallow handle, bent handle, mountain region handle, racing car handle; Resistance to compression be the mountain region the basis on two ends set up the polymer disk, and disk is sleeved on last, disk perimeter is provided with eight apertures, and eight thin bars are sub-packed in the hole, and nut tightens up, damping is provided with the column tube sticking at the front and back car, the middle damping spring that connects, outer cover is a cylinder, the front fork upper end connects handlebar, the back vent upper end connects vehicle frame, and the lower end is fixed on the forward and backward axle.Main points of the present utility model are its structural shape and manufacture craft.Its principle of work and method of operation are: the rotational force that utilizes the people to pedal pedal and axis rotation generation rotates crank wheel disk, drives flywheel and wheel by chain, drives car body and moves forward.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the structural representation of the utility model embodiment one.
