Abstract
A multifunctional angle square belongs to a novel instrument for measurement provided by drawing formation, and in particular is applicable for teachers and students to use in classroom teaching. The utility model is characterized by mainly consisting of an indicating dial, a finger, a scaleplate and compasses legs. Two different scales are marked on the indicating dial. The utility model has combined functions, thereby being capable of drawing, making angles, measuring side length, etc., and helping improve work efficiency and teaching quality.
Description
A kind of measuring utensil that provides in the making of drawing is provided multifunction angle square rule, and teachers and students use in the especially suitable classroom instruction.
At present, employed relevant teaching aid in classroom instruction uses as protractor, compasses, set square etc. are independent separately, act on single, to some situation that is difficult for setting-out, does the angle and need know the length of side at angle, adopt just inconvenience of existing individual tool.
The purpose of this utility model provides a kind of multifunction angle square rule, can realize the picture circle, does the angle, survey several different effects such as the length of side, and is easy to use.
The utility model is achieved in that mainly to be made up of indicating dial, pointer, scale and compasses angle.Indicating dial is marked with two kinds of different scales, and the one, the scale of indication angular dimension, the 2nd, utilize certain proportionate relationship to indicate the scale of picture radius of a circle size, pointer is used to refer to scale, thus the size of angles of display and radius, scale is used for surveying the length of side.The head of scale is the tip that is used for fixing picture circle usefulness.
Use this instrument, can realize drawing, do effects such as angle, the survey length of side, especially can measure certain length of side under the certain angle with this instrument, utilize indicating dial, also can show outside the size of drawn angle, be to show drawn radius of a circle size, another characteristics are that to adopt this instrument to be used for the length of side measured under a certain angle effective.It is to collect the multi-functional one that is, it is helpful to increase work efficiency and improve the quality of teaching.
Further specify below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of multifunction angle square rule
As seen from the figure, scale 3 tops are made up of indicating dial 1 and pointer 2, and scale 3 belows are made up of compasses angle 4.Indicating dial 1 indicates two kinds of different scales, and the one, indicate angular dimension, the 2nd, indicate drawn radius of a circle size, pointer is used to refer to scale, demonstrates angular dimension and radius size.Scale can be used to survey the length of side, and the scale head is to can be used to the fixedly tip of picture circle.
When implementing to use this instrument to do the angle, make the required angle position of pointer indication, according to the principle that the diagonal angle equates, the angle between scale equates with angle shown in the pointer, the angle of the certain angle size of drawing this moment.In physics teaching, use this instrument can measure the length of the arm of force quickly and easily.Utilize the radius indicating dial in addition, when pointer is indicated a certain position, the circle of the certain radius of can drawing size.
Claims (2)
1, multifunction angle square rule mainly are made up of indicating dial, pointer, scale and compasses angle, it is characterized in that being made up of indicating dial (1) and pointer (2) above the scale (3), and scale (3) below is made up of compasses angle (4).
2, by the described multifunction angle square rule of claim 1, it is characterized in that indicating dial (1) indicates the scale of angle, with the scale of the drawn radius of a circle size of scale.
