Abstract
The utility model discloses a direct pedal type new bicycle which comprises a vehicle frame, a front wheel, a rear wheel and a central axle under the vehicle frame. The two sides of the central axle are respectively provided with a helical gear which is co-axial with the wheel disc. The two ends of the central axle outside the helical gear are respectively provided with a lengthened pedal connecting rod. The two pedal connecting rods are respectively provided with propulsive keys and propulsive levers. The lower ends of the pedal connecting rods are in circular arc shape and are provided with grooves. The two ends of the superior side of the central axle and the position corresponding to the circular arc of the lower end of the pedal connecting rods are respectively provided with a transmitting wheel with a groove. The two grooves of the transmitting wheels connect with the grooves of the lower ends of the two pedal connecting rods by the tractive ropes. The two ends of the central axle sleeve barrel are provided with circular arc grooves and the grooves are respectively provided with propulsive key poker rods. The upper ends of the two propulsive key poker rods respectively insert into the inner of the slotted holes of one end of the propulsive key lever. The propulsive key poker rods are provided with springs. Therefore, the utility model has good force moment effect and is very comfortable and convenient for treading. The direct pedal type new bicycle has the advantages of high adaptability, simple structure, long service life and low use-cost.
Description
Affiliated technical field
The utility model relates to a kind of new bicycle, relates to a kind of formula of directly stepping on new bicycle of directly stepping on the formula driver train that adopts specifically.
Background technology
At present, bicycle driving of the prior art mechanism generally all is that circumference is foot-operated, the bicycle of this form need be with moving in a circle that pin does not stop, in the process that moves in a circle, pin can not utilize gravity fully, and the pin relatively effort that moves in a circle also, the moment weak effect is stepped on and is pedaled discomfort; And the texture ratio at the bicycle pedal place of this structure is easier to damage, and needs often to change, and has so not only increased use cost, and bicycle goes wrong cumbersomely halfway, causes a lot of troubles for people's use.
Summary of the invention
In order to overcome the deficiency of the existing foot-operated driving of bicycle circumference, the utility model provides a kind of formula new bicycle of directly stepping on, and this bicycle moment is effective, scrunches convenient and strength-savingly, and comformability is strong, and is simple in structure, easy to operate.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of formula new bicycle of directly stepping on, comprise vehicle frame, front vehicle wheel, axis below rear wheel and the vehicle frame, its structural feature is: the axis both sides respectively fixedly mount an angular gear coaxial with wheel disc, the foot-operated connecting rod of a lengthening is respectively installed at the axis two ends of angular gear outside, on two foot-operated connecting rods thrust button and thrust lever are installed respectively, foot-operated connecting rod lower end is circular arc and groove is arranged, at axis upside two ends and the corresponding position of circular arc, foot-operated connecting rod lower end a power wheel that has groove is installed respectively, two power wheel grooves have pulling rope to be connected with two foot-operated connecting rod lower end grooves, at axis sleeve two ends arc groove is arranged, the thrust button poke rod respectively is installed in the groove, and the upper end of two thrust button poke rods inserted in the slotted hole of thrust button lever one end thrust button poke rod place mounting spring respectively.
The beneficial effects of the utility model are, during the utility model work, when left foot is stepped on, left side thrust button poke rod is stirred an end of thrust button lever and is upwards lifted, the other end is then to the whereabouts, an end that falls is stirred thrust button and the engagement of axis angular gear, this moment, left angular gear and wheel disc rotated in the same way, rotate by chain drawing bicycle trailing wheel, when left foot is stepped on, left threading connecting rod pulling rope spurs two power wheels and rotates in the same way, and meanwhile the reverse pulling rope of right threading connecting rod affects the right threading connecting rod upwards to mention, when mentioning, right thrust button poke rod is stirred an end of thrust button lever to the whereabouts, the other end is then upwards lifted, on the end lifted stir thrust button and separate with the axis angular gear, to avoid the friction between thrust button and the angular gear; When right crus of diaphragm is stepped on, just produce effect same when stepping on left foot.Foot-operated connecting rod is alternately done and is pumped about realizing like this, by chain the bicycle rear wheel is advanced forward.The utility model since by bike the time bipod alternately do to step on up and down and pedal motion, the distance that both feet move is all the time in the bigger position of moment, so moment is effective; Because bipod is done in the course of nature stepping on up and down and pedaled motion by bike the time, steps on very comfortable convenience when pedaling, the people who particularly begins to learn by bike can feel to learn very easily, has to scrunch comfortable effect easily; Cyclist of the present utility model is long according to oneself height and leg, and can do bipod miles of relative movement is that stepping on of arbitrary value pedaled motion, has overcome to do many discomforts that the motion of circumference fixed range produces, so comformability is strong.The utility model can be applicable to perambulator, manual tricycle etc. simultaneously; The utility model is simple in structure, few easy workout part, and long service life, use cost is low.
