Abstract

The utility model relates to a novel bicycle. In the utility model, a shaft handle is connected with a connecting rod which is connected with a lever with pedals. The support frame of the lower side of a saddle is connected with a beam through a connecting pipe. The driving gear of the bicycle adopts the four-connecting rod principle, which causes the riding to be easy. The circular motions of the feet are changed into the upper and the lower rectilinear motions, and the effective work is increased. Because the corresponding structure requires that the seat is lower, the rider does not need to slide when getting on and getting off. The utility model has the advantage of bigger safety.

Description

Bicycle

The utility model relates to a kind of new bicycle, belongs to the daily life vehicle.

Used bicycle in people's daily life at present, main by pedal power drive footstalk, cause sprocket wheel to drive chain and make backgear promotion bicycle advance this structure, need rider's pin leg to do reciprocal circular movement, effectively merit is few, and the amount of exercise of pin leg is big, and is very big to the amount of expending of human body, time is long slightly, fatiguability, and vehicle seat top is big to the contact surface friction of human body, sits and feels more uncomfortable long afterwards.

The purpose of this utility model is in order to overcome above-mentioned deficiency, and provides a kind of band pedal lever and connecting rod, the new bicycle that connecting rod links to each other with footstalk.This bicycle only needs treadmill human pin to do upper and lower crank motion to get final product.

The utility model is in order to realize above-mentioned purpose, and concrete technical scheme is: this car comprises wheel, Che Liang, vehicle seat and footstalk.The footstalk front end links to each other with connecting rod, the connecting rod other end links to each other with the top of ⊥ shape lever, ⊥ shape lever front end dress pedal, and the rear end links to each other with the rear end of another lever, be connected with ball bearing of main shaft between footstalk and connecting rod, connecting rod and the lever, be connected with ball bearing of main shaft by middle front axle between lever and the lever.The connection pipe that bracing frame middle part dress below the vehicle seat links to each other with the car beam.

Characteristics of the present utility model are: laborsaving, adopt four connecting rod principles in the design, and change the circular movement of bipod into upper and lower straight-line motion, it is nearly 1/3rd that periodic distance has shortened, and effectively merit increases.In addition,, reduced whole center of gravity, avoided reaching forward and bring compressing, and need not slide when getting on the bus and getting off, had bigger safety both arms and both hands because corresponding structure requires the seat lower.

Concrete structure of the present utility model is provided by accompanying drawing 1--3.

Fig. 1 is the integral structure scheme drawing of new bicycle.

Fig. 2 is a new bicycle connection pipe front view.

Fig. 3 is a new bicycle connection pipe lateral plan.

Keystone configuration is among the figure: wheel 1, car beam 2, vehicle seat 3, footstalk 4, connecting rod 5, lever 6, pedal 7, middle front axle 8, bracing frame 9, connection pipe 10, screw 11, keep plate 12, bolt 13.

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

This new bicycle comprises wheel 1, car beam 2, vehicle seat 3 and footstalk 4.Footstalk 4 front ends link to each other with connecting rod 5, connecting rod 5 other ends link to each other with the top of ⊥ shape lever 6, the front end dress pedal 7 of ⊥ shape lever 6, and the rear end is connected by middle front axle 8 usefulness ball bearing of main shafts with the rear end of another lever, be connected with ball bearing of main shaft between the footstalk 4 and connecting rod 5, connecting rod 5 and lever 6.Bracing frame 9 middle part loads below the vehicle seat 3 take over 10, two screws 11 of connection pipe 10 end bands, and the cylindrical end of connection pipe 10 is inserted in the car beam 2, and bracing frame 9 is connected by the bolt 13 in two screws 11 of keep plate 12 usefulness with connection pipe 10.Owing to be horizontally disposed with two screws 11, so can guarantee that vehicle seat 3 is steady.Need not slide earlier in the time of by bike, directly be sitting on the vehicle seat 3, a pin props up ground, and another is foot-operated lives pedal 7 forward, steps on downwards, makes lever 6 drivening rods 5 that footstalk 4 is rotated forward around axis.With this simultaneously axis footstalk 4 that will drive another side rotate counterclockwise, thereby make the lever 6 that is attached thereto backward, upward movement, another lever is got back to the original place again when riding on earth, two pin Zhou Erfu instead back and forth scrunch, and car is constantly moved ahead.During parking, brake earlier, bipod just can with propping up.This car needs brake to remain intact.

Claims (3)

1, a kind of new bicycle is characterized in that comprising wheel, Che Liang, vehicle seat and footstalk, and the footstalk front end links to each other with connecting rod, and the connecting rod other end links to each other with the top of ⊥ shape lever, the front end dress pedal of ⊥ shape lever, and the rear end links to each other with the rear end of another lever.

2, new bicycle as claimed in claim 1 is characterized in that footstalk and connecting rod, is connected with ball bearing of main shaft between connecting rod and the lever, is connected with ball bearing of main shaft by middle front axle between lever and the lever.

3, new bicycle as claimed in claim 1 is characterized in that the bracing frame middle part load of vehicle seat bottom is taken over, two screws of connection pipe end band, and connection pipe links to each other with the car beam, and bracing frame and connection pipe are by the bolted connection in the keep plate usefulness screw.
