Abstract
The invention discloses a triangle, which comprises a first ruler (1), a second ruler (2) and a third ruler (3), wherein one end of the second ruler (2) is provided with a first protractor (4), one end of the third ruler (3) is provided with a second protractor (5), and scales are arranged on the first ruler (1), the second ruler (2) and the third ruler (3); and the end of the second ruler (2) with the protractor is hinged in a slidable frame groove (8) of the first ruler (1) through a movable shaft (6), and the third ruler (3) is embedded in the slidable frame groove of the first ruler (1) through a stipulated shaft (7). The triangle has low manufacture cost, is convenient to use, and is easy to carry.
Description
Technical field
The present invention relates to the educational aid field, especially a kind of set square.
Background technology
At present; In mathematical education, leg-of-mutton application is very extensive, draw one know two adjacent angle angles and an edge lengths, three edge lengths, or two edge lengths hand over triangle arbitrarily such as an angle; All more loaded down with trivial details by the routine mapping; Use ruler or set square, protractor and compasses, speed slowly and process is loaded down with trivial details, how not portable again thing is.
Summary of the invention
The present invention is that the slow and process of the leg-of-mutton instrument operating speed of present picture is loaded down with trivial details problem such as to be not easy to carry again in order to solve; A kind of set square is provided for this reason; Comprise first ruler 1, second ruler 2 and the 3rd ruler 3,, an end of second ruler 2 is provided with first protractor 4; One end of the 3rd ruler 3 is provided with on second protractor, 5, the first rulers 1, second ruler 2 and the 3rd ruler 3 and all is provided with scale; Second ruler, 2 band protractor ends are articulated in through movable axis 6 in the slider bar groove 8 of first ruler 1, and the 3rd ruler 3 embeds in the slider bar groove of ruler first ruler 1 through predetermined axis 7.
According to embodiments of the invention, said second ruler 2 can be around movable axis 6 rotation 0-180 degree, and the 3rd ruler 3 can be around fixed axis 7 rotation 0-180 degree.
According to embodiments of the invention, said second ruler, 2 protractor ends can be in the slider bar groove 8 of first ruler 1 parallel sliding.
The invention has the beneficial effects as follows:
Owing to adopted rule and the good matched combined of protractor, the triangle of the various needs of picture is accomplished immediately and accurately and reliably, simple in structure, cost is low, it is easy, easy to use to carry.
Description of drawings
The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a set square vertical view of the present invention;
Fig. 2 is a set square front view of the present invention.
The specific embodiment
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
Like Fig. 1, set square shown in Figure 2; It comprises first ruler 1, second ruler 2 and the 3rd ruler 3,, an end of second ruler 2 is provided with first protractor 4; One end of the 3rd ruler 3 is provided with on second protractor, 5, the first rulers 1, second ruler 2 and the 3rd ruler 3 and all is provided with scale; Second ruler, 2 band protractor ends are articulated in through movable axis 6 in the slider bar groove 8 of first ruler 1, and the 3rd ruler 3 embeds in the slider bar groove of ruler first ruler 1 through predetermined axis 7; Said second ruler 2 can be around movable axis 6 rotation 0-180 degree, and the 3rd ruler 3 can be around fixed axis 7 rotation 0-180 degree; Said second ruler, 2 protractor ends can be in the slider bar groove 8 of first ruler 1 parallel sliding.The present invention has been owing to adopted rule and the good matched combined of protractor, the triangle of the various needs of picture accomplished immediately and accurately and reliably, simple in structure, cost is low, and it is easy, easy to use to carry.
The present invention is not limited to the aforesaid specific embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
