Abstract
Bicycle work-saving device, relates to a kind of bicycle work-saving device, especially a kind of device that the acting of cyclist's self gravitation can be utilized to carry out power-assisted.Bicycle work-saving device of the present utility model, it is characterized in that it by the seat board connecting panel be connected as a single entity with seat board, be fixed on movable pulley that seat board connecting panel is together elevated with connecting panel, be fixed on two fixed pulleys on bicycle spider, the Compress Spring be fixed on spider, extension spring under sprocket wheel, the steel rope being connected assembly pulley, chain and the spider set up in the subtend of former footboard drives sprocket wheel form.Steel rope is connected with the chain on sprocket wheel by assembly pulley, and chain is connected with the extension spring be fixed under bicycle spider by stretcher axis.This work-saving device structure is simple, cheap, easy to use again, bicycle can be made to accelerate moving velocity and gradient capability, can temper waist and the whole body coordination ability of cyclist simultaneously by power-assisted, is a kind of well vehicle.
Description
Technical field
The present invention relates to a kind of work-saving device of bicycle, especially a kind of device that the acting of cyclist's self gravitation can be utilized to carry out power-assisted.
Background technology
Existing bicycle we be referred to as bicycle, as the term suggests be exactly drive sprocket rotation with after foot-operated bicycle pedal, sprocket wheel drives fixing rear wheel on the same axis, thus drive bicycle to travel forward, bicycle footboard drives of walking on level land is substantially out of question, but run into road surface complicated and grade ratio is larger time, foot exerts all one's strength very large, the little people of muscle power can only get off implementation, therefore the structure of bicycle can be improved, not only can drive with pin, can hoist by hip during body erect simultaneously and sit down subsequently, by the gravity acting of cyclist self, thus increase propulsive effort, more complex road surface can be adapted to.
Summary of the invention
The problem being exactly bicycle and cyclist's self gravitation can be utilized to drive to be solved in the utility model, provides a kind of structure simple bicycle work-saving device.
Bicycle work-saving device of the present utility model, it is characterized in that it by the seat board connecting panel be connected as a single entity with seat board, be fixed on movable pulley that seat board connecting panel is together elevated with connecting panel, be fixed on two fixed pulleys on bicycle spider, the Compress Spring be fixed on spider, extension spring under sprocket wheel, the steel rope being connected assembly pulley, chain and the spider set up in the subtend of former footboard drives sprocket wheel form.Steel rope is connected with the chain on sprocket wheel by assembly pulley, and chain is connected with the extension spring be fixed under bicycle spider by stretcher axis.
When bicycle runs into complex road surface and climbing situation time, the two foot-treadle of cyclist, health is that stance hip leave seat board, Compress Spring now below seat board draws secondary spring reset with another, seat board is raised automatically, when then sitting down, entire weight drops on seat board, seat board compresses the Compress Spring be fixed on spider with seat board connecting panel, simultaneously, another extension spring Tensile, seat board declines automatically, and the steel rope of assembly pulley drives the chain rotating sprocket be connected with sprocket wheel, thus drives bicycle to advance.The acting repeatedly that so goes round and begins again produces power-assisted.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
In accompanying drawing, each portion title is as follows:
1-fixed pulley, 2-movable pulley, 3-Compress Spring, 4-seat board, 5-seat board connecting panel, 6-fixed pulley, 7-steel rope, 8-drive sprocket, 9-chain, 10-stretcher axis, 11-extension spring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, bicycle work-saving device of the present utility model, by seat board 4, seat board connecting panel 5, movable pulley 2, Compress Spring 3, fixed pulley 1, fixed pulley 6, steel rope 7, drive sprocket 8, chain 9, extension spring 11 is formed, drive sprocket 8 is newly-increased sprocket wheel, install on the same axis with former bicycle drive sprocket and be in the subtend side of former sprocket wheel, pipe link on seat board 4 is inserted in the sleeve pipe on former spider, and with the seat board connecting panel 5 be closely connected by Compress Spring 3 when cyclist goes up a slope, constantly stand and sit down, thus by the Compress Spring 3 under seat board cyclist stand step on stretcher time automatic spring seat board stroke, when again sitting down, seat board declines, pulley rotation pulls steel rope 7 to drive drive sprocket 8 by the chain 9 be connected with steel rope, like this gravity of people is changed into and the propulsive effort of bicycle is done work, increase bicycle propulsive effort, chain 9 is connected with extension spring 11 by bicycle stretcher axis 10, guarantee that seat board resets.So go round and begin again, cyclist had both added power by bike, easily walks, also tempered waist and the whole body coordination ability of cyclist simultaneously when making it at complex road surface and go up a slope.
