Description
Technical field
This utility model is related to a kind of measuring scale, especially a kind of double precision graphometric square.
Background technology
It is known：Graphometric square includes drawing graphometric square and measurement double precision graphometric square, and drawing is main with graphometric square
It is used for surveying mapping size used in drawing course, measurement graphometric square is mainly used in what scene was measured to measurement point
Tape measure.
Existing measurement graphometric square typically adopts tape measure, tape measure to be divided into tape measure and ribbon；Existing tape measure is to measurement
Point is measured and can only obtain a kind of size of certainty of measurement；Therefore can only require to choose different according to different certainties of measurement
The tape measure of certainty of measurement.So as to the scope of application is less.Measure simultaneously after cannot the accuracy of logarithm value be estimated.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of double essences that can obtain two kinds of different measuring precision
Degree graphometric square.
This utility model solves the technical scheme adopted by its technical problem：Double precision graphometric square, including chi box, first
Tape measure, the second tape measure；First tape measure and the second tape measure are installed in chi box, and the chi box has chi end and hand-held
End；The chi end that goes out of the chi box is provided with directive wheel；First tape measure has the first chi head, and second tape measure has second
Chi head；First tape measure is extended by the guiding of directive wheel and chi end, and the first chi head is located at out on the outside of chi end 11；It is described
Second tape measure is extended by the guiding of directive wheel and chi end, and the second chi head is located at out the outside at chi end；First tape measure
The unit of the minimum scale that the minimum scale and the second tape measure having has is different；It is all provided with first tape measure and the second tape measure
It is equipped with footage handle.
Further, the handheld terminal of the chi box is provided with handle.
Further, in the chi box, the first tape measure side and the second tape measure side are respectively arranged with transition wheel, and described
One tape measure and the second tape measure are transitioned into directive wheel by transition wheel.
The beneficial effects of the utility model are：Double precision graphometric square described in the utility model is due to being provided with chi box
The tape measure of two kinds of different measuring precision, therefore in measurement process, the tape measure of two kinds of different measuring precision can be adopted to measurement
The size of point is measured, and measurement accuracy can be estimated according to two groups of data.Can measure suitable for two kinds simultaneously
Required precision, increased the scope of application of graphometric square.

Indicate in figure：1- chi boxes, the first tape measures of 2-, the second tape measures of 3-, 4- footage handles, 5- directive wheels, 6- transition wheels.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further illustrated.
As shown in Figures 1 to 4, double precision graphometric square described in the utility model, including chi box 1, the first tape measure 2, second
Tape measure 3；First tape measure 2 and the second tape measure 3 are installed in chi box 1, and the chi box 1 has chi end 11 and handheld terminal
12；The chi end 11 that goes out of the chi box 1 is provided with directive wheel 5；First tape measure 2 has the first chi head 21, second tape measure 3
With the second chi head 31；First tape measure 2 is extended by the guiding of directive wheel 5 and chi end 11, and the first chi head 21 is located at
Go out on the outside of chi end 11；Second tape measure 3 is extended by the guiding of directive wheel 5 and chi end 11, and the second chi head 32 is located at out
The outside at chi end 11；The unit of the minimum scale that the minimum scale and the second tape measure 3 that first tape measure 2 has has is different；
Footage handle 4 is provided with first tape measure 2 and the second tape measure 3.
During application：
Measurement point is first confirmd that, is then required according to certainty of measurement, selected using the first tape measure 2 on double precision graphometric square also
It is that the second tape measure 3 is measured；Two tape measures can also be selected while measuring.
First chi head 21 or the second chi head 31 are fixed in a measurement point, then hand-held graphometric square, by graphometric square
It is pulled to second measurement point, more the reading of the first tape measure 2 or the second tape measure 3, so as to measure corresponding data.
In sum, double precision graphometric square described in the utility model is due to being provided with two kinds of different measurings in chi box 1
The tape measure of precision, therefore in measurement process, the tape measure of two kinds of different measuring precision can be adopted to carry out the size of measurement point
Measurement, can be estimated to measurement accuracy according to two groups of data.Can require suitable for two kinds of certainties of measurement simultaneously, increase
The scope of application of graphometric square.
For the ease of operation, further, the handheld terminal 12 of the chi box 1 is provided with handle 13.
Do solid work with 1, chi box during stretching out or withdrawing in order to avoid tape measure and relate to, further, the chi box 1
Interior first tape measure, 2 side and the second tape measure side are respectively arranged with transition wheel 6, and first tape measure 2 and the second tape measure 3 pass through
Transition wheel 6 is transitioned into directive wheel 5.
