Abstract
The invention discloses a kind of portable mathematical modeling plotting units, including main scale, auxiliary scale, auxiliary scale card slot, shaft, the upper surface side of main scale is provided with and the sizable auxiliary scale card slot of auxiliary scale, one end between main scale and auxiliary scale is rotatablely connected by shaft, shaft can only make auxiliary scale rotate 90 degree, and auxiliary scale, which turns to after main scale is overlapped, to be located in the auxiliary scale card slot of main scale.When the present invention carries, ruler will be increased and increase cylinder clearance gauge and be contracted in main scale, auxiliary scale is folded on the auxiliary scale card slot of main scale again, volume just narrows down to the size of only main scale, it is easy to carry, when use, it is used if you need to 90 degree, auxiliary scale is then unfolded, volume increase ruler can also be unfolded to fathom, length etc., cylinder clearance gauge measures narrow space, it can also be tapered by assistance clearance gauge replacement, convenient for measuring narrow space, growth ruler can also be replaced with to the clinohedral of side triangle, convenient for purposes such as measurement gaps, it is easy to use, it is easy to carry, it has the value of popularization and application.
Description
Technical field
The present invention relates to a kind of to learn teaching aid more particularly to a kind of portable mathematical modeling plotting unit.
Background technique
Mathematical modeling is exactly to be solved to mathematical model, then basis according to practical problem come founding mathematical models
As a result solving practical problems are removed.
When needing from one practical problem of quantitative angle analysis and research, people will in-depth investigation and research,
Solution object information, on the basis of making and simplifying hypothesis, the analysis work such as inherent law, with the symbol of mathematics and language make statement come
Founding mathematical models.
In the prior art, mathematical modeling will use drawing tool mostly, and in the prior art mostly need using set square,
Ruler etc., but existing set square ruler excessively occupied space, are unfavorable for carrying, accordingly, there exist rooms for improvement.
Summary of the invention
The object of the invention is that providing a kind of portable mathematical modeling drawing to solve the above-mentioned problems
Device.
The present invention through the following technical solutions to achieve the above objectives:
The present invention includes main scale, auxiliary scale, auxiliary scale card slot, shaft, and the upper surface side of the main scale is provided with and the pair
The sizable auxiliary scale card slot of ruler, one end between the main scale and the auxiliary scale are rotatablely connected by the shaft, and described turn
Axis can only make the auxiliary scale rotate 90 degree, and the auxiliary scale, which turns to after main scale is overlapped, to be located in the auxiliary scale card slot of the main scale.
As an improvement, opening is arranged in the end of the main scale, hollow structure is set, in the hollow structure in the main scale
It is provided with growth ruler, the growth ruler can be slided in the hollow structure.
Preferably, the growth ruler scale display window of the upper surface setting and hollow structure perforation of the main scale.
As an improvement, the end of the main scale is provided with opening, hollow structure, the hollow structure are set in the main scale
Interior setting increases cylinder clearance gauge, and the growth cylinder clearance gauge can be slided in the hollow structure.
Preferably, the upper surface setting of the main scale and the growth cylinder clearance gauge scale of hollow structure perforation are shown
Window.
The beneficial effects of the present invention are:
The present invention is a kind of portable mathematical modeling plotting unit, compared with prior art, when the present invention carries,
Ruler will be increased and increase cylinder clearance gauge and be contracted in main scale, then auxiliary scale is folded on the auxiliary scale card slot of main scale, volume just contracts
It is so small to have only the size of main scale, it is easy to carry, in use, using if you need to 90 degree, then auxiliary scale is unfolded, can also be unfolded to increase production ruler
Fathom, length etc., cylinder clearance gauge measures narrow space, can also will assistance clearance gauge replacement it is tapered, convenient for measuring narrow sky
Between, growth ruler can also be replaced with to the clinohedral of side triangle, it is easy to use convenient for purposes such as measurement gaps, it is convenient for
It carries, has the value of popularization and application.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the side structure schematic diagram of main scale of the present invention；
Fig. 3 is main scale and auxiliary scale combinatorial construction schematic diagram of the invention.
In figure: 1- main scale, 2- auxiliary scale, 3- auxiliary scale card slot, 4- shaft, 5- increase ruler, 6- increases ruler scale display window,
7- increases cylinder clearance gauge, 8- increases cylinder clearance gauge scale display window.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in figures 1 and 3: the present invention includes main scale 1, auxiliary scale 2, auxiliary scale card slot 3, shaft 4, the upper surface of the main scale
Side, which is provided with, to be turned with the sizable auxiliary scale card slot of the auxiliary scale, one end between the main scale and the auxiliary scale by described
Axis rotation connection, the shaft can only make the auxiliary scale rotate 90 degree, and the auxiliary scale, which turns to after main scale is overlapped, is located at the master
In the auxiliary scale card slot of ruler.
As shown in Figure 2: opening is arranged in the end of the main scale, and hollow structure, the hollow structure is arranged in the main scale
It is inside provided with and increases ruler 5, the growth ruler can be slided in the hollow structure.
Preferably, the growth ruler scale display window 6 of the upper surface setting and hollow structure perforation of the main scale.
As an improvement, the end of the main scale is provided with opening, hollow structure, the hollow structure are set in the main scale
Interior setting increases cylinder clearance gauge 7, and the growth cylinder clearance gauge can be slided in the hollow structure.
Preferably, the growth cylinder clearance gauge scale display window of the upper surface setting and hollow structure perforation of the main scale
8。
Basic principles and main features and advantages of the present invention of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
