Abstract

The utility model discloses a bicycle mileage counter, relating to a device for counting and displaying the ride mileage of bicycles. The bicycle mileage counter is composed of a mechanical counter and a driving mechanism. The mechanical counter comprises mainly a cumulative counting wheel, a sectional counting wheel, a worm gear pair and a zero restoring handle, and the mechanical counter is fixed on the handlebar of a bicycle. The driving mechanism comprises screw gears in mesh, a worm, and a flexible shaft. The screw gears are arranged on the outer side of the rear shaft of the bicycle. When the screw gears is rotated synchronously with the rear shaft, the cumulative counting wheel and the sectional counting wheel can be driven by the worm, the flexible shaft and the worm gear pair to rotate and carry bit. In addition, the sectional counting wheel can return to zero through operating the zero restoring handle. The utility model can be widely used as mileage counters of various bicycles.

Description

Bicycle mileage counter

The utility model relates to a kind of device that is used to count and show the cycling mileage.

Bicycle is the traffic means of transport that people often use, and in city and rural area application is very widely arranged all.But bicycle of the prior art all is equipped with counting basically and shows the counting assembly of the mileage of riding, thereby the accumulation that is difficult to estimate bicycle life-span and the segmentation mileage of riding of riding, and therefore the function of bicycle also is subjected to some restrictions.

The mileage counter that the purpose of this utility model promptly is to design a kind of count enable and shows the cycling mileage.

To achieve these goals, the utility model utilizes gear train and mechanical counter to form a kind of mechanical bicycle mileage counter.Mechanical counter mainly is made up of stored counts wheel and fragmentation count wheel, is fixed on the bicycle handlebar by its box body; Gear train comprises intermeshing cross helical gear and worm screw and flexible axle, cross helical gear is installed in the outside of bicycle rear axle by bicycle rear axle skin and gear casing and can rotates synchronously with rear axle, and the two ends of flexible axle then link to each other with mechanical counter with worm screw respectively.Can rotate and carry by the stored counts wheel and the fragmentation count wheel of gear train driving device counter when bicycle rear axle rotates, realize bicycle accumulated distance counting and segmentation mileage counting.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model bicycle mileage counter.

Accompanying drawing 1 is the structural representation of the utility model bicycle mileage counter;

Accompanying drawing 2 is the structure and the scheme of installation of gear train;

With reference to the accompanying drawings 1 and accompanying drawing 2, the utility model bicycle mileage counter mainly is made up of mechanical counter and gear train.Gear train mainly comprises intermeshing cross helical gear 1 and worm screw 2 and flexible axle 3, cross helical gear 1 is fixed on the outside of bicycle rear axle by bicycle rear axle skin 4 and gear casing 5 and can rotates synchronously with rear axle, and the two ends of flexible axle 3 link to each other with mechanical counter with worm screw 2 respectively.Mechanical counter reaches back zero handle by worm couple, stored counts wheel, fragmentation count wheel and constitutes, and is fixed on the bicycle handlebar by its box body.Worm couple comprises intermeshing successively chopped-off head worm couple 6, middle worm couple 7 and final stage worm couple 8, and chopped-off head worm couple 6 links to each other with an end of flexible axle 3, and 8 of final stage worm couples and the first stored counts digit wheel intermesh.The stored counts wheel comprises the digit wheel 9 that is used to represent the accumulated distance number more than 5, all evenly indicates the 0-9 arabic numeral of totally 10 expression mileages on the wheel rim of each digit wheel, all has intermeshing with it carry idle wheel 10 between adjacent two digit wheels.The fragmentation count wheel comprises the digit wheel 11 that is used to represent the segmentation mileage number more than 4, all evenly indicate the 0-9 arabic numeral of totally 10 expression mileages on the wheel rim of each digit wheel, from each digit wheel of second order digit character wheel, the peach shape wheel 12 of working in coordination with time zero handle is installed all, between the first stored counts digit wheel and the first fragmentation count digit wheel intermeshing with it idle wheel 13 is housed.Return zero handle 14 and be installed on the mechanical counter box body by Handle axis 15 and can rotate by thorny arbor 15, return zero handle have more than 3 respectively with peach shape wheel 12 driving levers of working in coordination 16 and more than 3 respectively with the intermeshing coaxial carry idle wheel 17 of adjacent two fragmentation count digit wheels.Can make carry idle wheel 17 and fragmentation count digit wheel break away from engagement and take turns 12 by peach shape when pulling back zero handle makes the fragmentation count digit wheel get back to zero point.

The utility model is simple in structure, and is easy to install and use, both count enables and show the bicycle accumulation mileage of riding, also count enable and the display segment mileage of riding.Therefore, the utility model can be widely used as the mileage counter of various bicycles.
