Abstract
The utility model relates to a combined measurer ruler for mathematics teaching, which belongs to the technical field of cultural and teaching goods. At present, a graphometer and a ruler which are used in teaching stationery are both single products and are respectively used. If angles of larger dimensions are measured and straight lines are drawn, the graphometer and the ruler are inconvenient, and sometimes, measuring errors and line drawing errors can be caused. The utility model has the technical scheme that a right graphometer 1 and a left graphometer 2 are respectively fixed on a rotary shaft 3, a ruler 4 between the right graphometer 1 and the left graphometer 2 is sheathed on the rotary shaft 3 and is hinged with the rotary shaft 3, and both side surfaces of the ruler 4 are fixedly provided with pad layer boards 5 of the straight ruler. The utility model has the advantages that the combined measurer ruler for mathematics teaching has simple and convenient operation, the combined measurer ruler for mathematics teaching can be used for teachers and students to teach and do homework to enhance drawing efficiency and accuracy rate, the combined measurer ruler for mathematics teaching has dual purposes with one object for use with combination, and the combined measurer ruler for mathematics teaching has low cost and good popularization and generalization prospects. When the angles of the larger dimensions are measured, the ruler 4 can be rotated and positioned to required angles, and is convenient for drawing the straight lines. At ordinary time, the combined measurer ruler for mathematics teaching can also be used as the ruler.
Description
Technical field: the utility model relates to culture and education apparatus technical field, is that a kind of mathematical education is with making up the measurer chi more specifically.
Background technology: the graphometer and the ruler that use in the stationery of imparting knowledge to students at present are single product, use respectively, if it is just very inconvenient to measure the angle and the picture straight line of large-size, cause measure error and setting-out error sometimes.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is that a kind of mathematical education of design is with making up the measurer chi.Its technical scheme is: right semi-circle instrument 1 and left semicircle instrument 2 are separately fixed in the rotating shaft 3, and the ruler 4 between right semi-circle instrument 1 and left semicircle instrument 2 is enclosed within the rotating shaft 3 hinged with rotating shaft 3, and ruler 4 two sides are fixed with ruler bed course plate 5.The advantage of this utility model is: the reasonable in design practicality, the novelty that is skillfully constructed, easy to use, Faculty and Students are with this chi teaching and do one's assignment and improved mapping efficient and accuracy rate, this chi dual-use material is used in combination, and its low cost of manufacture has good penetration and promotion prospect.It is very convenient the ruler rotation can be navigated to institute's angle measurement degree picture straight line when measuring the large-size angle, also can work as ruler at ordinary times and use.
Description of drawings: Fig. 1 front view, Fig. 2 side view.In the accompanying drawing: 1, right semi-circle instrument, 2, the left semicircle instrument, 3, rotating shaft, 4, ruler, 5, ruler bed course plate.
The specific embodiment: right semi-circle instrument 1 and left semicircle instrument 2 are separately fixed in the rotating shaft 3, and the ruler 4 between right semi-circle instrument 1 and left semicircle instrument 2 is enclosed within the rotating shaft 3 hinged with rotating shaft 3, and ruler 4 two sides are fixed with ruler bed course plate 5.This chi is provided with right semi-circle instrument 1 and but left semicircle instrument 2 is regardless of all measuring angle uses of face anyway, ruler 4 two sides are fixed with ruler bed course plate 5 and help the picture straight line, when measuring the large-size angle, take measurement of an angle by right semi-circle instrument 1 and left semicircle instrument 2, navigate to measured angle by ruler 43 rotations around the shaft and read accurate angle value, can directly draw by ruler 4 as drawing straight line; When drawing straight line, ruler 4 can be forwarded to and be a linear position with right semi-circle instrument 1 and left semicircle instrument 2 and get final product when ruler uses.
Claims (1)
1, a kind of mathematical education is with making up the measurer chi, it is characterized in that: right semi-circle instrument (1) and left semicircle instrument (2) are separately fixed in the rotating shaft (3), ruler (4) between right semi-circle instrument (1) and left semicircle instrument (2) is enclosed within that rotating shaft (3) is gone up and rotating shaft (3) is hinged, and ruler (4) two sides are fixed with ruler bed course plate (5).
