Abstract

The utility model discloses a reverse-pedal bicycle which can allow a rider to throw a chest and straighten the waist, wherein, a driving device is that a driving gear is driven by a crank shaft, a driven gear is driven by the driving gear, and the driving gear and the driven gear are rotated oppositely. A wheel disk is driven by the driven gear through a driven shaft, a chain is driven by the wheel disk, and a flywheel arranged on a rear wheel shaft is driven by the chain to realize the ahead running of the bicycle. The utility model is suitable for two-wheel bicycles, man-powered tricycles and children carts.

Description

A kind of rider of making bicycle that straight waist is kicked backward of to square one's shoulders

The utility model relates to the bicycle production technical field, can the square one's shoulders bicycle of straight waist of a kind of specifically rider of making.

Now, sell on the market, the bicycle that people use all is that both feet are pedaled forward, realizes crankshaft revolution, and car moves ahead.But there is a shortcoming in this bicycle, is exactly that the rider tends to bend over, the back of a bow, especially when upward slope or fatigue.Be still people's the main vehicle at Chinese bicycle, it is unfavorable to cause health as long-term use, particularly harmful especially to teenager's body development.Moreover, this mode of pedaling forward also rather allows the cyclist feel effort.

The utility model is to want to provide a kind of rider of allowing the straight waist of can squaring one's shoulders, when reducing to pedal firmly, avoid the teenager is grown the bicycle of harm.

The technical solution of the utility model is as follows:

Driving device structure of the present utility model is that crank shaft drives driving gear, and driving gear cooperates with the driven gear backward rotation.Driven gear is assemblied on the driven shaft, and driven shaft is fixed on the rear column, and wheel disc also is housed on the driven shaft, and wheel disc cooperates with chain, and chain drives the flywheel on the hind axle, to realize car to overtake.

Driving device structure of the present utility model can also be that driving gear and driven gear are assemblied in the gear case, and gear case places the five-way position of car, fixes with preceding cant beam, rear column, the flat wooden fork welding in two backs.Crank shaft is from the break-through of gear housing both sides, and driving gear is driven by crank shaft, and driving gear cooperates with the driven gear backward rotation, driven gear is assemblied on the driven shaft, and driven shaft also is equipped with wheel disc from the break-through of gear housing both sides on the driven shaft, wheel disc cooperates with chain, drives the flywheel on the hind axle.

The motion that the utility model has the advantages that the human body that can make the cyclist, waist, leg more meets human motion physiology, can accomplish to square one's shoulders, straight waist, breathe freely, does not have the sensation of feeling suffocated, and reduces the generation of hunchback, is of value to the healthy of rider.

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

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

Fig. 2 is the structural representation of the utility model embodiment 2.

Embodiment 1: as shown in Figure 1, driving gear 1 driving gear 1 is housed on crank shaft 9 to be cooperated with driven gear 2 backward rotation, driven gear 2 is contained on the driven shaft 3, driven shaft 3 is fixed on the rear column 7, also has wheel disc 4 on the driven shaft, wheel disc 4 cooperates with chain 5, the flywheel that chain 5 drives on the hind axle.Cant beam before other is designated 6 among the figure, the flat wooden fork in 8 backs.

Embodiment 2: as shown in Figure 2, driving gear 1 and driven gear 2 are assemblied in the gear case 10, and gear case 10 places the five-way position of car, and with preceding cant beam 6, rear column 7, flat wooden fork 8 fixed crank axles 9 in back and driven shaft 3 are from gear case 10 both sides break-through; Driving gear 1 is contained on the crank shaft 9, and driving gear 1 cooperates with driven gear 2 backward rotation, and driven gear 2 is assemblied on the driven shaft 3, also is equipped with wheel disc 4 on the driven shaft 3, and wheel disc 4 cooperates with chain 5, the flywheel that chain 5 drives on the hind axle.

The utility model is not only applicable to bicycle, is equally applicable to manual tricycle and carriage for children.Therefore, the bicycle of all employing the utility model actuating devices all should fall within the utility model protection.
