Description
Technical field
The present invention relates to a kind of dip stick, especially a kind of double precision graphometric square.
Background technology
Known: graphometric square includes drawing graphometric square and measurement double precision graphometric square, and drawing graphometric square is main
Drawing course uses for surveying mapping size, measurement graphometric square, be mainly used in on-the-spot to measuring what point measured
Tape measure.
Existing measurement graphometric square typically uses tape measure, and tape measure is divided into tape measure and ribbon；Existing tape measure is to measurement
Point measures the size that all can only obtain a kind of certainty of measurement；Therefore can only require to choose difference according to different certainties of measurement
The tape measure of certainty of measurement.Thus the scope of application is less.Cannot the accuracy of logarithm value be estimated after measuring simultaneously.
Summary of the invention
The technical problem to be solved is to provide a kind of double precision that can obtain two kinds of different measuring precision and surveys
Paint chi.
The technical solution adopted for the present invention to solve the technical problems is: double precision graphometric square, including chi box, the first volume
Chi, the second tape measure；Described first tape measure and the second tape measure are installed in chi box, and described chi box has chi end and hand-held
End；The chi end that goes out of described chi box is provided with directive wheel；Described first tape measure has the first chi head, and described second tape measure has second
Chi head；Described first tape measure is extended by the guiding of directive wheel and chi end, and the first chi head is positioned at outside chi end 11；Described
Second tape measure is extended by the guiding of directive wheel and chi end, and the second chi head is positioned at the outside of chi end；Described first tape measure
The unit of the minimum scale that the minimum scale having and the second tape measure have is different；It is all provided with on described first tape measure and the second tape measure
It is equipped with footage handle.
Further, the handheld terminal of described chi box is provided with handle.
Further, in described 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 all transitioned into directive wheel by transition wheel.
The invention has the beneficial effects as follows: double precision graphometric square of the present invention is owing to being provided with two kinds of differences in chi box
The tape measure of certainty of measurement, therefore during measuring, can use the tape measure of two kinds of different measuring precision to measuring the size put
Measure, measurement accuracy can be estimated according to two groups of data.Two kinds of certainty of measurement requirements can be applicable to simultaneously,
Add the scope of application of graphometric square.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, double precision graphometric square of the present invention, including chi box the 1, first tape measure the 2, second tape measure
3；Described first tape measure 2 and the second tape measure 3 are installed in chi box 1, and described chi box 1 has chi end 11 and handheld terminal 12；
The chi end 11 that goes out of described chi box 1 is provided with directive wheel 5；Described first tape measure 2 has the first chi head 21, and described second tape measure 3 has
There is the second chi head 31；Described first tape measure 2 is extended by the guiding of directive wheel 5 and chi end 11, and the first chi head 21 is positioned at
Outside chi end 11；Described second tape measure 3 is extended by the guiding of directive wheel 5 and chi end 11, and the second chi head 32 is positioned at chi
The outside of end 11；The unit of minimum scale that described first tape measure 2 has and the minimum scale that the second tape measure 3 has is different；Institute
State and be provided with footage handle 4 on the first tape measure 2 and the second tape measure 3.
During application:
First confirm that measurement point, then according to certainty of measurement requirement, select to use the first tape measure 2 on double precision graphometric square to go back
It is that the second tape measure 3 measures；Two tape measures can also be selected to measure simultaneously.
First chi head 21 or the second chi head 31 being fixed on one measure on point, the most hand-held graphometric square, by graphometric square
It is pulled to second and measures point, the more first tape measure 2 or reading of the second tape measure 3, thus measure corresponding data.
In sum, double precision graphometric square of the present invention is owing to being provided with two kinds of different measuring precision in chi box 1
Tape measure, therefore during measuring, can use the tape measure of two kinds of different measuring precision that the size measuring point is measured,
Measurement accuracy can be estimated according to two groups of data.Two kinds of certainty of measurement requirements can be applicable to simultaneously, add survey
Paint the scope of application of chi.
For the ease of operation, further, the handheld terminal 12 of described chi box 1 is provided with handle 13.
Do solid work with 1, chi box during stretching out or regaining in order to avoid tape measure and relate to, further, described chi box 1
Interior first tape measure 2 side and the second tape measure side are respectively arranged with transition wheel 6, and described first tape measure 2 and the second tape measure 3 all pass through
Transition wheel 6 is transitioned into directive wheel 5.
