Description
Technical field
The utility model relates to field of vehicles, especially a kind of bicycle.
Background technology
Existing bicycle need with bipod alternate cycles ground whole circle scrunch two pedals, pedal drive floral disc wheel moves in a circle, bipod ceaselessly whole circle rotates the physiological property not meeting people, effort and easily tired, riding speed is slower, particularly to run into when blowing or climb suffering more, bring great inconvenience to the trip of people.
Therefore in Chinese patent application (CN200820091303.9), disclose a kind of foot-operated labour-saving bicycle, change the whole circle of pedal into the driving of trampling and realizing bicycle that only need circulate up and down.Foot-operated labour-saving bicycle main body is by vehicle frame, vehicle seat, handlebar, front-wheel and several large parts composition of trailing wheel, vehicle frame both sides and trailing wheel coaxially respectively fixedly mount a sprocket wheel, sprocket wheel front, by the hinged floral disc wheel of click structure on the vehicle frame of trailing wheel both sides, floral disc wheel is connected by chain with sprocket wheel, floral disc wheel is driven by ratchet, the treadle of a band pedal is respectively installed in floral disc wheel both sides, treadle extends to bicycle direct of travel, two treadles are connected by a steel wire, steel wire rides on the pulley that arranges on cycle frame, left and right pin is placed on pedal by bicyclist, rotate to floral disc wheel during inferoanterior Pedalling, floral disc wheel transmits motion on minor sprocket by chain, left and right pin firmly drives floral disc wheel to rotate before lower, so just can realize bicycle to move ahead.Rider drives the power thrusts of bicycle to be inferoanterior, and the back upper place of the person be do not have object to support because of this person more tired out after for a long time firmly, be inconvenient to exert oneself.The Hard link of steel wire rope also brings a kind of impact to human foot joint and knee joint simultaneously, rides for a long time unfavorable to the person.
Utility model content
The utility model technical issues that need to address are to provide a kind of bicycle had an effect by bicyclist's body weight, save bicyclist's muscle power, realize the buffering to manipulator's lower limb in foot-operated process simultaneously, make operation more comfortable.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of bicycle, comprise vehicle frame side and the co-axially fixed sprocket wheel of rear wheel, the vehicle frame in sprocket wheel homonymy front is hinged with the floral disc be connected with sprocket wheel by chain to take turns, vehicle frame both sides and floral disc are taken turns and are coaxially respectively connected a treadle, the treadle of both sides is connected by steel rope, steel rope is by being fixed on the pulley support on vehicle frame, treadle extends between floral disc wheel and sprocket wheel, the junction of treadle and steel rope is provided with recoil spring, treadle is one in front and one in back fixed two stretchers, stretcher is positioned at the below of vehicle seat.
The further improvement of technical solutions of the utility model is: tandemly on described vehicle frame fix two vehicle seats.
The further improvement of technical solutions of the utility model is: described pulley midway location is provided with a groove preventing steel rope from departing from pulley.
The further improvement of technical solutions of the utility model is: described sprocket wheel is the cone pulley structure be made up of the sprocket coaxiality of multiple different-diameter.
Owing to have employed technique scheme, the technological advance that the utility model obtains is:
The treadle of bicycle of the present utility model is arranged between large faceplate wheel and minor sprocket, treadle extends back, and make the stretcher on treadle corresponding to the below of the health of bicyclist, bicyclist has an effect at the downward rear when trampling stretcher, bicyclist can by gravity acting, more meet the custom of having an effect of human body, save the muscle power of bicyclist, if treadle extends forward, then pedal can away from human body, bicyclist is being sitting on vehicle seat, is lifted by leg and exerts oneself forward, and it can be very uncomfortable.Treadle extends to the reversing sense of bicycle running simultaneously, and ground foreign material in driving process can be avoided to go on treadle or stretcher; Especially irregular upward slope road surface, the treadle extended back avoids treadle lower end and withstands the hard object such as ground and the Peril Incident causing bicycle to roll forward.
The junction of treadle and steel rope is provided with recoil spring, and recoil spring realizes bicyclist's buffering to operator's lower limb in foot-operated process, reduces this Hard link of steel rope to the impact of tricycle joint of lower extremity, makes ride more comfortable.
The treadle of both sides is one in front and one in back respectively provided with two stretchers, two people can rides simultaneously, trample different stretchers.It is less that amplitude trampled by the nearer stretcher of distance floral disc wheel, is applicable to trampling of the fast frequency of bicyclist; But although the strength needed when distance floral disc wheel stretcher far away tramples that amplitude is little tramples is smaller, be applicable to the occasion of the useless muscle power such as climbing.Bicycle of the present utility model arranges vehicle seat, but is only trample up and down when riding, and can not be sitting on vehicle seat, time tired or can be sitting on vehicle seat on mild road surface.Two bike saddles can allow bicyclist be sitting on different vehicle seats, switch different to trample position and angle, are convenient to tired alleviation.
Two vehicle seats on vehicle frame coordinate two stretchers on treadle to expand the range of use of bicycle, add the enjoyment of riding, and save rider's muscle power.
Pulley midway location is provided with groove, and prevent steel rope from pulley repeatedly moving process, departing from pulley, riding for safety provides safeguard.
Multiple different-diameter composition cone pulley structure is arranged to by sprocket wheel, and cone pulley structure is provided with gearshift, meets bicyclist and improving bicycle speed or saving unrestricted choice between muscle power at a slow speed.
The utility model with step on compared with the bicycle pedaled before and after the circumference of routine, the dynamic dead angle of mode of trampling of conventional bicycle, can lose time and strength, bicycle of the present utility model does not have dynamic dead angle, can save strength.The utility model can also be used on the foot-operated equipment such as water cycle, three-wheel vehicle.
