Abstract
The utility model provides the laborsaving device of bicycle is held the case and is constituted by foot rest lever subassembly, orbit bearing, guide rail shaft. Ride passerby and pedal running -board 1, drive foot rest lever fulcrum axle 10 and rotate around the axis to rotate on 5 outer lanes on the orbit bearing along with fulcrum bearing 4, because orbit bearing 5 eccentric settings, the event is along with foot rest lever fulcrum axle 10 rotates on 5 outer lanes on the orbit bearing, foot rest lever 3 can be in guide rail fixing bearing 7's spout flexible the slip, pedal shaft 2 is apart from centraxonial distance, the kinetic moment can change thereupon promptly. The device has realized in afterburning interval extension foot rest lever, increase moment for it is laborsaving to ride, shorten the foot rest lever in non - afterburning interval, avoid the foot rest lever overlength to plague for riding. The speed of not sacrificing can be guaranteed in this high -speed laborsaving device of bicycle's invention, can realize the more laborsaving purpose of riding again, lets more people select the green trip of bicycle, promotes the popularization of bicycle and the development of environmental protection cause.
Description
Technical field
The utility model belongs to technical field of bicycles, is a kind of bicycle high speed work-saving device.
Background technology
Existing bicycle is to trample pedal with bipod, drives bicycle walking by foot-driven lever rotary toothed disk.During cycling, effort size depends on riding
The length of bar, the foot-driven lever length of existing bicycle is changeless, the most laborious when riding.In the case of existing, laborsaving is real by speed changing structure
Existing, but labour-saving speed simultaneously can slow down, and the most laborsaving speed can be the slowest, it is difficult to meets the demand of people.
Summary of the invention
The purpose of this utility model is to overcome the drawbacks described above of existing bicycle structure, it is provided that a kind of bicycle high speed work-saving device.
This utility model technical scheme is as follows:
This bicycle high speed work-saving device, solid including pedal, pedal shaft, foot-driven lever, fulcrum roller, track bearing, axis fixing hole, guide rail
Dead axle holds, guide rail bearing case, fixed pivot, foot-driven lever fulcrum shaft and other findings.Bicyclist pedals pedal, drives pedal rod fulcrum shaft
Around central axis, and rotate on track bearing outer ring with fulcrum roller, due to track bearing eccentric setting, so that with foot-driven lever fulcrum shaft at track
On bearing outer ring rotate, foot-driven lever can in the chute of bearing fixed by guide rail telescopic slide, pedal shaft distance axis distance, i.e. kinetic moment can be therewith
Change.When plumbness crossed by foot-driven lever, pin starts reinforcing, to foot-driven lever forward front lower place state close to the vertical shape to time reinforcing terminate, this is interval for adding
Power is interval, actual acting interval the most by bike.This bicycle high speed work-saving device, it is achieved that at above-mentioned afterburning interval elongation foot-driven lever, increase
Moment so that ride laborsaving；At non-afterburning interval shortening foot-driven lever, it is to avoid foot-driven lever is long makes troubles to riding.This laborsaving dress of bicycle high speed
The invention put both can guarantee that does not sacrifices speed, and can realize again riding more labour-saving purpose, allows more people select bicycle Green Travel, promotes certainly
The popularization of driving and the development of environmental protection cause.

Detailed description of the invention
Below in conjunction with the accompanying drawings and be embodied as case the utility model is described in further detail, but not as to restriction of the present utility model.
Bicycle high speed work-saving device as shown in Figure 1 and Figure 2, including pedal 1, pedal shaft 2, foot-driven lever 3, fulcrum roller 4, track axle
Hold 5, axis fixing hole 6, guide rail fix bearing 7, guide rail bearing case bonnet 8, fixed pivot 9, foot-driven lever fulcrum shaft 10.
In this bicycle high speed work-saving device, track bearing 5 is off arranging, and its center of circle offsets from the location mid-shaft of driving, before being positioned at axis
Enter on direction, by fixed pivot 9, the inner ring of track bearing 5 is fixed on cycle frame.Four guide rails are had to fix bearing in guide rail bearing case
7 are arranged symmetrically, and are fixed on the bonnet 8 of guide rail bearing case, and the bonnet 8 of guide rail bearing case has axis fixing hole 6 to fix with axis so that
Guide rail bearing case is with middle shaft rotation.Guide rail is fixed a circle chute on bearing 7 outer ring, four guide rails are fixed bearing 7 and are distributed in foot-driven lever 3 both sides,
Foot-driven lever 3 can slide in the chute of bearing 7 fixed by guide rail.The outer ring of fulcrum roller 4 is that the outer ring with track bearing 5 is fixing, foot-driven lever 3
Rear end slip in the chute that bearing 7 fixed by guide rail, foot-driven lever fulcrum shaft 10 coordinates with fulcrum roller 4.Bicyclist pedals pedal 1, drives pin
Treadle fulcrum shaft 10 is around central axis, and rotates on track bearing 5 outer ring with fulcrum roller 4, due to track bearing 5 eccentric setting, therefore with
Foot-driven lever fulcrum shaft 10 to rotate on track bearing 5 outer ring, foot-driven lever 3 meeting telescopic slide, pedal shaft 2 in the chute of bearing 7 fixed by guide rail
The distance of distance axis, i.e. kinetic moment can change therewith.When plumbness crossed by foot-driven lever 3, pin starts reinforcing, forwards front lower place to foot-driven lever 3 and connects
During nearly plumbness, reinforcing terminates, and this interval is afterburning interval, actual acting interval the most by bike.This bicycle high speed work-saving device, real
Show at above-mentioned afterburning interval elongation foot-driven lever, increased moment so that ride laborsaving；At non-afterburning interval shortening foot-driven lever, it is to avoid foot-driven lever is long
Give the inconvenience brought of riding.
The utility model is not limited to above-mentioned embodiment, if to the various changes of utility model and modification without departing from spirit of the present utility model and
Scope, if these are changed within the scope of belonging to claim of the present utility model and equivalent technologies with modification, then the utility model is also intended to comprise this
A little changes and modification.
