Description

Adjustable labour-saving pedal

A kind of adjustable effort-saving pedal that is assemblied in the multiscale on the various bicycles.

The research of bicycle labor saving at present is many, and the speed change chain then easily falls chain and damage based on the speed change chain, and is difficult for the configuration chain cover.

The purpose of this utility model provides a kind of adjustable effort-saving pedal of multiscale.

This pedal has not only been eliminated above-mentioned drawback, and runs into against the wind or go up a slope by bike at need, behind the class of adjusting pedal, rides fast, no matter the length of people's leg all can reach the labour-saving purpose by adjusting the class of pedal in the same old way.

The utility model is achieved in that at first, central axis hole on the sleeve, drift bolt hole and bicycle middle shaft join, when the approach road is uneven, to pedal handle and forward level attitude to, step on a grade pin hook, the hook tail backs down the pressure hook spring leaf and leaves high-grade knock hole, simultaneously under the elastic force effect of superior displacement spring leaf, make to pedal in the handle activity and move, rotate then to make and pedal handle vertical (being that pedal is above axis), continue to step on pedal, make low-grade registration mast flatten displacement spring leaf down, make a grade pin hook, hook tail enter low-grade knock hole and reset, so far finished high-grade step-down class.

As be intended to laborsavingly, and when meeting against the wind or going up a slope, ride, need the low-grade class that uprises, at first will pedal handle and go to level, and step on a grade pin hook, continuation will be pedaled handle and forward vertically (being that pedal is below axis) to, step on pedal and make the hook tail of grade pin hook enter high-grade knock hole, can finish this purpose.After selecting high and low class for use, tighten nail silk and will pedal handle and be fixed on the sleeve.

The utlity model has following advantage:

1, reasonable in design, laborsaving, as being first class (being low-grade) with the long 165cm of the crank of former bicycle, second class (being top grade) prolongs 65cm, and length prolongs about 40%, then laborsaving 40%; According to experiment showed, the crank of present various car is prolonged 65cm, when smooth road or upward slope were ridden, pedal did not bump ground, and pedal also hits less than the front vehicle wheel FE Tiler during turning.

2, make simply, many grades adjustable, no matter but the length of the equal root a tree name leg of child adult is suitable with the adjustment of handlebar saddle simultaneously.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a left side of the present utility model pedal overall structure scheme drawing;

Fig. 2 is an A-A generalized section of the present utility model;

Fig. 3 is a B-B generalized section of the present utility model.

Below in conjunction with accompanying drawing in detail this structure of tool of the present utility model and operational detail are described in detail.

See shown in the accompanying drawing 1-3, the utility model by drift bolt hole (1), decide spring silk (2), high-grade registration mast (3), superior displacement spring leaf (4), sleeve (5), shelves pin hook (6), down displacement spring leaf (7), pedal handle (8), low-grade registration mast (9), pedal hole (10), low-grade knock hole (11), pressure hook spring leaf (12), central axis hole (13), jackscrew (14), silk hole slot (15), decide spring silk (16), hook tail (17), high-grade knock hole (18), wear dog hole (19) formation.

Central axis hole (13) on the sleeve (5), drift bolt hole (1) join with bicycle middle shaft.

Sleeve (5) is socketed in pedals handle (8) outside.Sleeve (5) outside has a jackscrew (14), and jackscrew (14) places in the hole slot (15).

Respectively with deciding spring silk (2) fixedly superior displacement spring leaf (4) and following displacement spring leaf (7), decide spring silk (16) and fixing pressure hook spring leaf (12) on the sleeve (5).

Sleeve (5) left side connects central axis hole (13), and a side of central axis hole (13) vertically connects drift bolt hole (1).

Shelves pin hooks (6) pack in the high-grade knock hole (18) hook tail (17) by the dog hole (19) of wearing on the sleeve (5).

Pedal handle (8) and run through sleeve (5).Have high-grade registration mast (3) and low-grade registration mast (9) on the handle (8) pedaling, be drilled with high-grade knock hole (18), be drilled with low-grade knock hole (11) in the corresponding position, side of low-grade registration mast (9) in the corresponding position, side of high-grade registration mast (3).Has pedal hole (10) in the lower end of pedaling handle (8).

The utility model can be to various car crank proper extension, or sets class by the lifting saddle.Situation is ridden in visual examination at ordinary times when adjusting class, should make the vehicle frame top rail be lower than the leg length of oneself.In a word, according to the stature height of oneself, that the adjustment of handlebar saddle is suitable.

The right side pedal is identical with left side pedal structure, and it constructs outline.

The central axis hole of right side pedal is connected with the chain wheel of bicycle, and its central axis hole is bigger.
