Description

A kind of mathematic(al) construction apparatus easy to use
Technical field:
The utility model relates to the mathematic(al) construction instrument used in mathematical education, mathematical studying and Mathematics Application, what be specifically related to is a kind of mathematic(al) construction apparatus easy to use.
Background technology:
Various mathematic(al) construction instrument often will be used in mathematical education, mathematical studying and Mathematics Application, as compasses, rule, set square, protractor etc., existing several common mathematical drawing tool is nearly all independent individuality, people are when mathematic(al) construction, just to not complete one or both mappings, but multiple mapping will be completed, so the office bag (school bag) of people is inner often compasses, rule, set square, protractor etc. are housed simultaneously, causes people to carry and use equal inconvenience.
Summary of the invention:
The purpose of this utility model is to provide a kind of mathematic(al) construction apparatus easy to use, and it is all that independent individuality causes carrying and inconvenient problem with use for solving current several common mathematical drawing tool.
The technical scheme that the utility model adopts is: this mathematic(al) construction apparatus easy to use comprises housing, housing is rectangle, a side of housing is open import and export, the another one side of housing is provided with compasses, housing is transparent plastic casing, is provided with the first ruler, the second ruler, the 3rd ruler, protractor in housing; Housing end face has chute, and the first ruler is connected with slide, and one end of the second ruler is connected by little axle with the first ruler, and the other end of the second ruler is free end; One end of 3rd ruler is also connected by little axle with the first ruler, and the other end of the 3rd ruler is also free end; Housing bottom surface has chute, and protractor is connected with slide; Compasses are made up of bar-shaped trough, mobile supporting leg, fixed supporting leg, fixed supporting leg is fixed on housing side, the end of fixed supporting leg is sucker, mobile supporting leg is formed by Mobile base being installed supporting leg, the end of supporting leg is stationary magazine creel, pencil is inserted in stationary magazine creel, and Mobile base is arranged in bar-shaped trough, is slidably connected with bar-shaped trough.
The front panel of such scheme middle shell is positioned at entrance end and is provided with groove, and the first ruler and protractor are all out exposed from groove, the first ruler and protractor is released in housing to facilitate.
The utility model has following beneficial effect:
Ruler, protractor, compasses are concentrated and are designed on housing by the utility model, housing can also play collecting effect, during use, the first ruler, the second ruler, the 3rd ruler can not only realize making straight line, right angled triangle, acute triangle, flat shape quadrangle are made in the realization that can also cooperatively interact, and the second ruler or the 3rd ruler are coordinated with protractor respectively and can also make straight line and the tangent figure of circular arc; In addition, compasses can also be utilized to justify, carry and use all very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The schematic diagram that Fig. 2 is the first ruler in the utility model, protractor is extracted out in housing.
1 housing, 2 first rulers, 3 second rulers, 4 the 3rd rulers, 5 protractors, 6 little axles, 7 import and export, and 8 bar-shaped troughs, 9 move supporting leg, 10 fixed supporting legs, 11 suckers.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, this mathematic(al) construction apparatus easy to use comprises housing 1, housing 1 is rectangle, a side of housing 1 is open import and export 7, the another one side of housing 1 is provided with compasses, housing 1 is transparent plastic casing, and housing 1 is shallow shell, is provided with the first ruler 2, second ruler 3, the 3rd ruler 4, protractor 5 in housing 1, housing 1 end face has chute, and the first ruler 2 is connected with slide, and one end of the second ruler 3 is connected by little axle 6 with the first ruler 2, and the other end of the second ruler 3 is free end, one end of 3rd ruler 4 is also connected by little axle 6 with the first ruler 2, the other end of the 3rd ruler 4 is also free end, during use, shown in composition graphs 2, first ruler 2 is released in housing 1, second ruler 3 and the 3rd ruler 4 can just to be followed in housing out, second ruler 3 and the 3rd ruler 4 can tilt to any direction as required, can the two intersect, now triangle can be made, the two can be positioned at the same side of the first ruler 2, second ruler 3 and the 3rd ruler 4 can also lay respectively at the both sides of the first ruler 2, specifically can rotate to the position of needs as required.
Housing 1 bottom surface has chute, and protractor 5 is connected with slide.Front panel is positioned at entrance end and is provided with groove, the first ruler 2 and protractor 5 all out exposed from groove, to facilitate, the first ruler 2 and protractor 5 are released in housing 1.
Compasses are made up of bar-shaped trough 8, mobile supporting leg 9, fixed supporting leg 10, fixed supporting leg 10 is fixed on housing 1 side, the end of fixed supporting leg 10 is suckers 11, mobile supporting leg 9 is formed by Mobile base being installed supporting leg, the end of supporting leg is stationary magazine creel, pencil is inserted in stationary magazine creel, and Mobile base is arranged in bar-shaped trough 8, is slidably connected with bar-shaped trough 8.During use, the large young pathbreaker of the circle drawn as required moves supporting leg 9 and slides into corresponding position, is adsorbed on blackboard, rotary shell 1, just can draws the circle of needs by fixed supporting leg 10 by sucker 11.
