Abstract
The utility model relates to a student scale that is a multiple using scale for students. The multiple using scale comprises a main scale, an active scale and a detachable and semicircular protractor. The active scale is inserted into the interlayer of the main scale, and a dead bolt of the main scale is passed through a long opening of the main scale and a center circle in one end of the main scale, so the main scale is connected with the active scale. On one side edge near the main scale, the dead bolt of the active scale is passed through the long opening of the active scale and an active slipping stripe, so the active slipping stripe is fixedly connected with the active scale. Complicated figures can be drawn by shifting the active scale and changing angle of the active scale. The semicircular and detachable protractor is inserted and connected into a groove on one end of the negative of the main scale. The utility model has the advantages of simple structure, more function, being used in drawing complicated figure, for example angles, circulars, multilaterals and polyhedrons.
Description
Affiliated technical field
The utility model relates to a kind of student's chi, especially a kind of student's multipurpose ruler.
Background technology
At present, the student is the ruler of single type with chi, and function is more single, and this chi can play the effect of drawing straight line and tolerance length, as for drawing the angle, drawing and justify, draw parallel lines, draw perpendicular bisector, polygon etc. the figure of complexity is just powerless.If draw complicated figure, just need employ multiple drawing instrument, and the student a kind of both simple, that function is many just seems necessary especially with the appearance of chi.
Summary of the invention
In order to overcome the drawback of existing student with the chi function singleness, the utility model proposes a kind of student's multipurpose ruler, this chi is simple in structure, and function is more, can draw comparatively complicated figures such as angle, picture circle, picture polygon.
The technical scheme that its technical problem that solves the utility model adopts is: this multipurpose ruler is assembled by main scale (1), adjustable rule (6) and dismountable semicircle protractor (9) three parts, its main scale (1) is two superimposed frameworks together of rectangular thin slice, and the centre is a space layer; And a side of framework leaves opening, at the middle part of main scale (1) and have a long opening of microscler main scale (10); Adjustable rule (6) is the thin slice of a rectangle, and the long opening of adjustable rule (7) is left at its middle part, and one end center has a circular hole; After adjustable rule inserts the centre of main scale (1), main scale gim peg (5) passes the center hole of long opening of main scale (10) and adjustable rule (6) one ends, main scale (1) and adjustable rule (6) are linked together, on side edge near main scale, pass long opening of adjustable rule (7) and movable draw runner (8) by adjustable rule gim peg (5), movable draw runner is fixedly connected on the adjustable rule; In the groove of main scale (1) egative film one end, insert a connection semicircular protractor (9), protractor (9) is removable detachable.
Its good effect is, owing to adopted such scheme, can make the utility model reach simple in structure, and function is more, can draw complicated figure such as angle, circle, polygon, polyhedron.
Description of drawings
The utility model is described in further detail below in conjunction with the timely embodiment of accompanying drawing.
Accompanying drawing 2 is the utility model side sectional structure principle schematic.
Among the figure, 1. main scale, 2. opening, 3. displacement activity chi, 4. main scale gim peg, 4-1. hold-doun nut, 4-2. band pin button, 5. adjustable rule gim peg, 5-1. hold-doun nut, 6. adjustable rule, the 7. long opening of adjustable rule, 8. movable draw runner, 9. protractor, the 10. long opening of main scale.
The specific embodiment
In Fig. 1, adjustable rule gim peg (5) bottom has one to lift plate, can hold adjustable rule (6), the top of adjustable rule gim peg (5) is helicitic texture, it and hold-doun nut (5-1) are equipped with, the movable draw runner (8) that has central hole, can be inserted in adjustable rule gim peg (5), (5-1) is tightened by hold-doun nut, and after movable draw runner (8) and adjustable rule (6) were fixing, movable draw runner (8) can be close on the edge of main scale (1) and slide, utilize this kind sliding function of adjustable rule (6), can draw parallel lines easily, after hold-doun nut (5) was loosening, adjustable rule (6) can be drawn the angle, bisector of angle, parallel lines, complex figure such as polygon and stereogram.
In Fig. 2, main scale gim peg (4) bottom also has one to lift plate, it can hold adjustable rule (6), the top of main scale gim peg (4) also is threaded structure, it and hold-doun nut (4-1) are equipped with, main scale gim peg (4) passes the circular hole and the long opening of main scale (10) of adjustable rule (6), and (4-1) screws by nut, can main scale (1) last slice be fixed together with adjustable rule (6).The inside of main scale gim peg (4) is a columniform space, wherein one of sliding fit installation has the band pin button (4-2) that little spring heads on, if band pin button (4-2) is pinned, make the pin nail on chart board, pen is fixed in long opening of adjustable rule (7) or the long opening of main scale (10), can draws circle easily.
