Abstract
A multifunctional angle measuring and arc drawing instrument comprises an elongated base and a scale. The elongated base is provided with a scale accommodating tank which can accommodate the scale. Central side surfaces of the scale accommodating tank are provided with visible semicircular angle measurement scales. A lower end of the scale is rotatably fixed in the scale accommodating tank and is provided at a circle center position of the semicircular angle measurement scales. The lower end of the scale is provided with a pointer which is matched with the semicircular angle measurement scales of the base in the scale accommodating tank for indicating an angle. The scale is provided with a positioning device for the tools such as a paintbrush. In the multifunctional angle measurement and arc drawing instrument according to the technical solution, the scale is matched with the semicircular angle measurement scales which are visible on the elongated base that is provided with ruler scales. The multifunctional angle measuring and arc drawing instrument can be used for drawing a constant-angle arc and measuring the angle. Furthermore the multifunctional angle measuring and arc drawing instrument can be directly used as the ruler. Because the base is provided with the scale accommodating tank which can be used for accommodating the scale, the scale can be accommodated wherein in idle state. Furthermore high convenience in carrying and small volume are obtained.
Description
Technical field
The utility model relates to a kind of teaching aid, and relating in particular to is to be used for picture arc and angulation usefulness.
Background technology
On the classroom, can effectively explain relevant knowledge with educational aid, as protractor, ruler, compasses etc.Usually the instrument that is used for picture arc or angulation in the teaching is compasses, protractor.Usually these educational aids only possess simple function, and the educational aid number of packages is more, and volume is bigger, so carry very inconvenient; In addition, very inconvenient when needing frequently to change educational aid in use and especially drawing arc, also lose time simultaneously, reduce efficient on class.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly carries, multi-functional angulation cyclograph easy to use.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of multi-functional angulation cyclograph, comprise strip base and scale, have the scale accommodating groove that can hold scale on the described strip base, scale accommodating groove central lateral plane is provided with visual semicircle angle measuring calibration, the rotatable home position that is fixed in the scale accommodating groove and places the semicircle angle measuring calibration in scale lower end, described scale lower end has pointer, and pointer cooperates the indication angle with base semicircle angle measuring calibration in the scale accommodating groove; Scale is provided with the positioner of paintbrush class instrument.
The further technical scheme of the utility model is: described scale is provided with slideway, described positioner is the movable block that is nested on the slideway and can moves along slideway, movable block be provided with install and fix paintbrush class instrument install and fix the hole and with the securing member of the fastening location of scale.The side of strip base is provided with the ruler scale.
Adopt the multi-functional angulation cyclograph of technique scheme, semicircle angle measuring calibration visual on scale and the strip base that is provided with the ruler scale cooperates, both can draw and decide angle arc and angulation, also can directly use as ruler, and, when idle, scale can be received capsule wherein because of its base has the scale accommodating groove that can hold scale, easy to carry, volume is little.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of embodiment of the multi-functional angulation cyclograph of the utility model, comprise the strip base 1 and the scale 2 that have ruler scale 5, have the scale accommodating groove 3 that can hold scale 2 on the described strip base 1, scale accommodating groove 3 central lateral planes are provided with visual semicircle angle measuring calibration 4, present embodiment strip base adopts transparent material, can adopt transparent plastic to make, so that the reading of scale.The rotatable home position that is fixed in the base scale accommodating groove 3 and places semicircle angle measuring calibration 4 in scale 2 lower ends, present embodiment adopts telescopic pin 6 nonadjustable signals 2 of spring, push the flat end 6a of pin 6 in use, make point 6b eject, be easier to the center of circle and fix.When idle, push pin flat end 6a once more, make point 6b withdraw, avoid point 6b to stab and be beneficial to and take in, and scale 2 rotations can be pressed in the scale accommodating groove 3, so that carry.Described scale 2 lower ends have pointer 2a, and pointer 2a cooperates the indication angle with the semicircle angle measuring calibration 4 of strip base 1 in scale accommodating groove 3.Scale 2 is provided with the positioner that paintbrush class instrument is installed, the scale 2 of present embodiment is provided with slideway 7, described positioner is the movable block 8 that is nested on the slideway 7 and can moves along slideway 7, movable block 8 be provided with install and fix paintbrush class instrument install and fix hole 10 and with the securing member 9 of scale 2 fastening location, make paintbrush class instrument slide and change the arc radius along slideway 7.
