Description

Combination changeable ruler
Technical field
The present invention relates to a kind of measurement and drawing instrument, be specially one combination changeable ruler.
Background technology
In daily studying and living, it is often necessary to use various measurement and drawing instrument.The most complete a set of student Ruler, 45 degree of set squares, 60 degree of set squares and protractor is included with chi.Ruler generally only has the measurement scope of 15cm or 20cm, And set square, protractor occupy larger space, carry some inconvenience.Ruler, set square and protractor in use, often Use can be affected owing to being accidentally lost the most a certain part.
Summary of the invention
The purpose of the present invention, is to improve existing ruler, set square, protractor and optimum organization, a kind of group of exploitation Close changeable ruler.
In order to solve above-mentioned technical problem, the present invention by the following technical solutions:
A kind of combination changeable ruler, including ruler first, ruler second, ruler third;Ruler first, ruler second, ruler third length it Than beingRuler second be respectively arranged at two ends with rotating shaft first, rotating shaft second, one end of ruler first, ruler third passes through rotating shaft respectively First, rotating shaft second is rotationally connected with ruler second;Ruler first is respectively equipped with location click beetle, locating button second with the other end of ruler third, fixed Position click beetle, locating button second are box and pin;Ruler first, ruler second, ruler third a side on be carved with length scales first, length respectively Anale settting scale second, length scales third, another side of ruler first, ruler second is respectively equipped with one section to ruler first, ruler second Blade side's inflexed protractor circular arc first, protractor circular arc second, protractor circular arc first, protractor circular arc second is 1/4th Circular arc, arc radius is identical.
Locating button third, locating button fourth is further respectively had on described ruler first, ruler third, locating button third to ruler first one end Distance is equal to ruler first lengthLocating button fourth is equal to ruler first length to the distance of ruler third one endFixed Position button third, locating button fourth are box and pin.
Owing to using above-mentioned design, the present invention can produce following change and beneficial effect:
1, long ruler is added.Rotate ruler first, ruler third rotating around rotating shaft first, rotating shaft second, make ruler first, ruler second, ruler Third is located on a straight line, is made up of the ruler of a lengthening ruler first, ruler second, ruler third.
2,45 degree of set squares and protractor.Location click beetle is fastened with locating button second, by ruler first, ruler second, ruler third Constitute one 45 degree of set squares, the side of protractor circular arc first, protractor circular arc second Yu ruler second constitute a protractor.
3,60 degree of set squares.Locating button third is fastened with locating button fourth, ruler first, ruler second, ruler third constitutes 1 Degree set square.
4, folding ruler.Ruler first, ruler second, ruler third may be folded on together, and volume after folding diminishes, and is convenient for carrying.
Ruler, set square, the function of protractor are organically combined by the present invention, reached when three is used alone without The effect that method reaches, carries and uses convenient, and is not easy to lose any of which part.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the composition schematic diagram of the present invention.
Fig. 2 is the schematic diagram that the present invention constitutes 45 degree of set squares.
Fig. 3 is that the present invention constitutes the schematic diagram adding long ruler.
Fig. 4 is the schematic diagram that the present invention constitutes 60 degree of set squares.
Fig. 5 is the schematic diagram after the present invention folds.
In figure: 1. ruler first, 2. ruler second, 3. ruler third, 12. rotating shaft first, 23. rotating shaft second, 13. location click beetles, 31. is fixed Position button second, 14. length scales first, 24. length scales second, 34. length scales third, 15. protractor circular arc first, 25. protractor circles Arc second, 32. protractor center marks, 16. locating buttons third, 36. locating button fourths.
Detailed description of the invention
As it is shown in figure 1, the present invention includes ruler first 1, ruler second 2, ruler the third 3.Ruler first 1, ruler second 2, ruler the third 3 Length ratio isRuler second 2 be respectively arranged at two ends with rotating shaft first 12, rotating shaft second 23, one end of ruler first 1, ruler the third 3 It is rotationally connected with ruler second 2 by rotating shaft first 12, rotating shaft second 23 respectively.It is fixed that the other end of ruler first 1 and ruler the third 3 is respectively equipped with Position click beetle 13, locating button second 31, location click beetle 13, locating button second 31 are box and pin.The one of ruler first 1, ruler second 2, ruler the third 3 Be carved with length scales first 14, length scales second 24, length scales the third 34 on bar side respectively, ruler first 1, ruler second 2 another One section of protractor circular arc first 15 to the bending of the blade direction of ruler first 1, ruler second 2, protractor circular arc is had respectively on bar side Second 25, protractor circular arc first 15, protractor circular arc second 25 is quarter circular arc, and arc radius is identical.
Further respectively having locating button the third 16, locating button fourth 36 on ruler first 1, ruler the third 3, locating button the third 16 is to ruler first 1 The distance of end it is connected equal to ruler first 1 length with ruler second 2Locating button fourth 36 is connected to ruler the third 3 with ruler second 2 The distance of end is equal to ruler first 1 lengthLocating button the third 16, locating button fourth 36 are box and pin.
As in figure 2 it is shown, location click beetle 13 fastens with locating button second 31, ruler first 1, ruler second 2, ruler the third 3 composition 45 degree Set square, the side composition protractor of protractor circular arc first 15, protractor circular arc second 25 and ruler second 2, protractor circular arc first 15, Being carved with angle scale in protractor circular arc second 25, the point midway of ruler second 2 side is carved with protractor center mark 32, protractor Circular arc first 15, the center of circle of protractor circular arc second 25 are positioned at protractor center mark 32.
As it is shown on figure 3, ruler first 1, ruler second 2, ruler the third 3 is positioned at same straight line, constitute the ruler of a lengthening, long scale Chi first 14, length scales second 24, length scales the third 34 is the length scales of continuous scale.
As shown in Figure 4, locating button the third 16 fastens with locating button fourth 36, ruler first 1, ruler second 2, ruler the third 3 constitute 60 Degree set square.
As it is shown in figure 5, ruler first 1, ruler second 2, ruler the third 3 folds, it is simple to receive and carry.
