Abstract

The utility model relates to a bicycle viameter, which comprises a dynamic ball, a static ball, an electrical contact, a power supply, a spring, a computing element and a casing. The electrical contact, the power supply and the computing element form a circuit which is installed in a first cavity of the casing; the static ball and the spring are connected with each other and installed in a second cavity of the casing; and the dynamic ball is installed on a wheel. The bicycle viameter has the advantages of accurate metering, simple structure and low manufacturing cost.

Description

A kind of bicycle use taximeter

Technical field

The utility model relates to a kind of taximeter, more particularly, relates to a kind of bicycle use taximeter.

Background technology

Usually there is complex structure in existing bicycle use taximeter or the inaccurate problem of having the records of distance by the log, the bicycle taximeter of Chinese patent CN93244712.0 for example, and complex structure is unfavorable for utilization and extention; And the digital display of Chinese patent CN92206062 shows that the bicycle distance and speed counter adopts comparatively complicated Circuits System, and is convenient inadequately in the manufacturing.

The utility model content

The purpose of this utility model is to solve problems of the prior art, and a kind of simple in structure, convenient and practical bicycle use taximeter is provided.

The following technical proposals that adopted the utility model solves above-mentioned technical matters:

A kind of bicycle use taximeter comprises moving ball, quiet ball, electric contact, power supply, spring, computing element and housing; Electric contact, power supply and computing element are formed the loop, and are installed in first cavity of housing, and quiet ball is connected with spring, is installed in second cavity of housing, and moving ball is installed on the wheel.

Described computing element is made up of counter, counter and display.

The beneficial effects of the utility model are: accurately have the records of distance by the log (1); (2) simple in structure, low cost of manufacture.

Embodiment

Bicycle use taximeter as shown in Figure 1 comprises moving ball 1, quiet ball 2, electric contact 3, power supply 4, spring 5, computing element 7 and housing 9; Electric contact 3, power supply 4 and computing element 7 are formed the loop, and are installed in first cavity 8 of housing 9, and quiet ball 2 is connected with spring 5, is installed in second cavity 6 of housing 9, and moving ball 1 is installed on the wheel 10.

Computing element 7 is made up of counter, counter and display.

The moving circle of wheel 10 revolutions, moving ball 1 contacts once with quiet ball 2, when moving ball 1 contacts with quiet ball 2, quiet ball 2 is pressed in the housing 9 contacts with electric contact 3, thereby making electric contact 3, power supply 4 and computing element 7 form the loop connects, the rolling counters forward of computing element 7 demonstrates numerical value by display after calculating mileage by counter.

Claims (2)

1. bicycle use taximeter, comprise moving ball, quiet ball, electric contact, power supply, spring, computing element and housing, it is characterized in that, electric contact, power supply and computing element are formed the loop, and be installed in first cavity of housing, quiet ball is connected with spring, is installed in second cavity of housing, and moving ball is installed on the wheel.

2. bicycle use taximeter according to claim 1 is characterized in that described computing element is made up of counter, counter and display.
