Abstract
The utility model discloses a labor-saving bicycle which comprises a handlebar, a front wheel, a back wheel, pedals, a seat, a beam, a back support and a support arm, wherein a diameter of the back wheel is larger than that of the front wheel, a lower fork connected with the front wheel is in a bending-backward shape, a handlebar shaft connected with the lower fork is provided with a stopping rod, and the lower fork is provided with a baffle which is matched with a stopping rod. Due to the fact that the diameter of the back wheel is larger than that of the front wheel, compared with the prior art, the diameter of the front wheel is small and the length of a bicycle body is shortened correspondingly, the resistance in climbing is small, and the bicycle can start quickly. Due to the fact that the lower fork on the front wheel is bended backward, the arrangement of the baffle and the stopping rod can enable a rider to ride stably and prevent the rider from distorting the front handlebar in emergency.
Description
Technical field
The utility model relates to a kind of daily vehicle, is specifically related to a kind of bicycle.
Background technology
Bicycle is the more common vehicle, and especially in the society of advocating environment protection, health, increasing youngster tends to go on a journey by bike, play.Existing bicycle arranges former and later two wheels more, and front-wheel is identical with the trailing wheel size.Concerning the tourist that part is gone on a journey by bike, this class bicycle is not easy to climbing.
The utility model content
The technical problems to be solved in the utility model is that the bicycle climbing is slow, and a kind of fast labour-saving bicycle of climbing is provided.
The technical solution of the utility model realizes in the following manner: a kind of labour-saving bicycle, comprise handlebar, front-wheel, trailing wheel, pedal, vehicle seat, Che Liang, after poppet and leg, described rear wheel diameter is greater than the diameter of front-wheel, the lower fork that links to each other with front-wheel is backward bending-like, the handlebar axis that links to each other with lower fork is provided with pin, and lower fork is provided with the baffle plate that cooperates with pin.
Described leg is arranged in the middle of pedal rotating shaft and the hind axle.
Be connected with hood on the described after poppet, described hood comprises the hollow tubular that is fixed on the vehicle frame, and connection pipe is plugged in the hollow tubular, the connection pipe top is provided with jack, the connection pipe top links to each other with top supporting frame, and locating rack is plugged in the jack, is connected with ceiling on locating rack, the top supporting frame.
Described vehicle seat links to each other with lower bracket, and described car beam comprises entablatrance and oblique beam, and the projection on the lower bracket can be slided along the chute on the oblique beam, and the lower bracket lower end is provided with damping spring.
Be connected with wind wheel on described front-wheel and the trailing wheel.
Rear wheel diameter of the present utility model is greater than front wheel diameter, and with respect to prior art, its front wheel diameter has diminished, the vehicle body distance shortens accordingly, and its resistance is little in the time of climbing, starting is fast.And the lower fork in the utility model on the front vehicle wheel is backward bending, and baffle plate and pin are set can be so that walking be more stable, and handle is crooked before can prevent from running into unexpected situation the time.

Fig. 2 is the structural representation after hood removes ceiling.
Fig. 3 is that schematic diagram is looked on the left side of hood.
Fig. 4 is vehicle seat part connection diagram.
The specific embodiment
As shown in Figure 1, a kind of labour-saving bicycle comprises handlebar 2, front-wheel 1, trailing wheel 7, pedal, vehicle seat 5, car beam 4, after poppet 11 and leg 6.In the utility model: described trailing wheel 7 diameters are greater than the diameter of front-wheel 1, and the lower fork 9 that links to each other with front-wheel 1 is backward bending-like, and the handlebar axis 10 that links to each other with lower fork 9 is provided with pin 8, and lower fork 9 is provided with the baffle plate 3 that cooperates with pin 8.Described pin 8 can make bolt or other materials that is fixed on the lower fork 9, and when handlebar was subject to External Force Acting and turns round suddenly, pin 8 was run into baffle plate 3 and can not be rotated further, and prevents from bringing harm because turning round suddenly to the rider.
Improve as second point of the present utility model: described leg 6 is arranged in the middle of pedal rotating shaft and the hind axle.Leg is set like this, can be so that stop more stable.
Thirdly improve as of the present utility model: be connected with hood on the described after poppet 11, described hood comprises the hollow tubular 12 that is fixed on the vehicle frame 11, connection pipe 13 is plugged in the hollow tubular 12, connection pipe 13 tops are provided with jack 15, connection pipe 13 tops link to each other with top supporting frame 14, locating rack 17 is plugged in the jack 15, is connected with ceiling 16 on locating rack 17, the top supporting frame 14.Arrange after the hood, can be rider's shading wind and rain and the sun.And the hood in the utility model can fold, with locating rack 17 from jack 15 interior taking-ups, can implement device folding.When not wanting to use hood, connection pipe 13 is got final product from hollow tubular 12 interior taking-ups.When wind and rain is larger, a plastic cloth can be sticked on the hood, but windshield block rain.
Hood in the utility model also can be used on other two-wheeled electric cars or the motor bike.
As the 4th improvement of the present utility model: described vehicle seat 5 links to each other with lower bracket 18, and described car beam 4 comprises entablatrance 4-2 and oblique beam 4-1, and the projection on the lower bracket 18 can be slided along the chute on the oblique beam 4-1, and lower bracket 18 lower ends are provided with damping spring 19.This structure can on scraggly road, reduce the vibrations on the vehicle seat.
As the 5th improvement of the present utility model: be connected with wind wheel 20 on described front-wheel 1 and the trailing wheel 7.In operation, wind wheel can take full advantage of natural wind, promotes bicycle to move ahead, against the wind, wind wheel 20 can both play a role with the wind.Wind wheel also can be installed in front and back wheel axle two ends.
