Abstract

The utility model relates to a pen type gage for charts, which is composed of a pen type casing, a rolling quantity wheel in the casing, a transmission mechanism and an accumulating device, wherein, the pen type casing is provided with a window for displaying the data; or the whole casing is a transparent body without the window; the lower end of the inside of the casing is provide with the rolling quantity wheel; the rolling quantity wheel is fixed on the transmission mechanism; the transmission mechanism is connected with the accumulating device which is arranged on the upper part of the casing. The utility model has the advantages that the utility model regenerates that the length of an engineering drawing and modes of corresponding engineering quantity are traditionally measured by the proportional scale, brings convenient and quick budget and final accounting of the engineering drawing, reduces labor intensity and enhances speed and precision of measure.

Description

The pen type gage for chart

The utility model relates to a kind of pen type gage for chart, is applicable to the quantities metering of building, finishing, apparatus and process, engineering construction figure such as electric.

In the past during the quantities in computational engineering figure, the traditional left hand of general employing takes engineer's scale to measure on figure, the computation schema that the right hand adds up by the counter segmentation, so not only engineering drawing pre-, the final accounts workload is huge, labour intensity is high, and during with the various arc length on the engineer's scale computational engineering figure, broken line length, its speed and precision also can't improve.Therefore be badly in need of breaking this traditional quantitative model, design a kind of easy to use, metering device efficiently.

The purpose of this utility model is to provide a kind of simple in structure, easy to use, quick at the technical matters of above-mentioned existence, the long-pending pen type figure length measuring of measuring, add, be combined into the whole body.

The purpose of this utility model by following technical proposals in advance to realize:

It is that gear train and accumulator are formed by the wheel of the rolling amount in pen type housing and the housing.Wherein, on the pen type housing, offer window, show that in order to numeral also can not offer window, whole housing is made by transparent material.In the pen type housing, be provided with two axles, and can freely turn round, one is arranged on the bottom of housing, another design position more than the bottom, being fixed with respectively on the wheel shaft of bottom rolls puts wheel and power wheel, is fixed with two power wheels on the wheel shaft of above position respectively, housing top is fixed with accumulator, have transmission shaft on the accumulator, be fixed with power wheel on this transmission shaft, the upper and lower position be provided with driving-belt in twos between the power wheel.

Described gear train also can adopt gear transmission mode to make its measurement more accurate.

The utility model has the advantages that:

1, the usage ratio chi that breaks traditions measures the length in the engineering drawing and the pattern of correspondingly quantities.Alleviated and carried out the labour intensity that quantities is calculated in the engineering drawing, can use pen type figure the length among the figure to be finished a piece of writing at one go easily, thereby accelerate the quantities computing velocity, brought unprecedented convenient, fast for pre-, the final accounts of engineering drawing with length measuring.

2, this product is long-pending measures, adds, closes, quantities among the computational engineering figure, needn't use traditional left hand again takes engineer's scale to measure on figure, the right hand connects the computation schema that the counter segmentation adds up, and just can open-and-shutly accurately obtain measuring the result so long as streak part with pen type figure with length measuring among the figure.

3, particularly the various arc length on the computational engineering figure, the speed and the precision of broken line length have more only road part, are to use engineer's scale incomparable.

4, pen type figure with length measuring have volume little, be convenient to carry, be more suitable for working-yard work.

5, change the model of accumulator and the radius of inner driven wheel, can realize being applied on the engineering drawing of any ratio and measure.

Describe the utility model in detail below in conjunction with accompanying drawing:

Shown in Fig. 1-5, it is made up of rolling amount wheel 8, gear train and accumulator 10 in pen type housing 14 and the housing 14.Offer window 1 on the housing 14, in order to display digit.Also can not offer window, whole housing 14 is made by transparent material, directly display digit.The bottom is provided with wheel shaft 7 in the housing 14, wheel shaft 7 two ends and the stick of housing upper shaft hole, and can freely turn round, be fixed with rolling amount wheel 8 and power wheel 6 on the wheel shaft 7, more up position is provided with another wheel shaft 4 in the bottom, be fixed with power wheel 5 and power wheel 12 on this wheel shaft 4 respectively, housing 14 internal upper parts are fixed with accumulator 10, can select the commercially available prod for use, have transmission shaft 9 on the accumulator 10, be fixed with power wheel 8 on this transmission shaft 9, be provided with driving-belt 13 between power wheel 6 and power wheel 5, be provided with driving-belt 11 between power wheel 12 and power wheel 3, the reset button on the accumulator 10 is 2, can also be provided with pen clip 18 on the housing 14, pen holds 16.

The course of work of the present utility model is as follows:

1, when using the pen type gage for chart to begin to measure, at first press reset button 2, make it to drive number implement by the transmission gear in the accumulator 10 and return zero, the numeral of at this moment digital display window 1 is shown as the zero-bit state.

2, the rolling amount on being fixed on wheel shaft 7 wheel 8 contacts when beginning to rotate with plan, wheel shaft 7 will drive the power wheel 6 that is fixed on this synchronously, driving power wheel 5 by driving-belt 13 simultaneously rotates, power wheel 5 and power wheel 12 rotate synchronously, driving power wheel 3 by driving-belt 11 again rotates, power wheel 3 is finally realized the purpose of automatic data display by the counting gear work of transmission shaft 9 drive accumulators 10.
