Abstract
The utility model discloses a segment dividing and line drawing ruler which comprises a first straight ruler and a second straight ruler. The first straight ruler and the second straight ruler are connected and fixed by a hinge pin. The segment dividing and line drawing ruler is characterized in that the free ends of the first straight ruler and the second straight ruler are respectively provided with a first segment endpoint positioning pin and a second segment endpoint positioning pin; dividing scales are arranged on the second straight ruler; a sliding sleeve is arranged on the second straight ruler; and a translation ruler parallel to the first straight ruler is fixedly arranged on the sliding sleeve by a bolt. The segment dividing and line drawing ruler has a simple structure, is convenient to use, can be used for accurately drawing divided segments and is time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of improvement of primary school mathematics teaching aid, specifically branch line drawing ruler such as a kind of line segment.
Background technology
At present; Teacher talks about in the line segment five equilibrium in last mathematics class; Method commonly used is to adopt ruler and compasses that line segment is calculated the back on blackboard, to carry out five equilibrium, and this method not only wastes time and energy, inconvenient operation; And the student sounds also bad understanding, also increased teacher's labour intensity simultaneously.
Summary of the invention
The purpose of the utility model be to provide a kind of simple in structure, easy to operate, can be accurately with the branch line drawing rulers such as line segment of line segment five equilibrium.
For reaching above purpose; The technical scheme that the utility model adopted is: branch line drawing rulers such as line segment; Constitute by first ruler and second ruler; First ruler is connected through bearing pin with second ruler to be fixed, and it is characterized in that: the free end of first ruler and second ruler is respectively equipped with first extremity of segment point location pin and second extremity of segment point location pin, on second ruler, is provided with evenly divided; On second ruler, be provided with slip cap, be provided with the translation chi that is parallel to first ruler through bolt on the slip cap.
The utility model is also implemented through following measure: described first ruler and second ruler are the transparent plastic chi; Described first extremity of segment point location pin and second extremity of segment point location pin are respectively perpendicular to the chi face of first ruler and second ruler.
The beneficial effect of the utility model is: simple in structure, easy to use, can accurately finish the line segment five equilibrium, and time saving and energy saving.
Description of drawings
Fig. 1 is the utility model structure schematic top plan view;
1, first ruler among the figure; 2, second ruler; 3, first extremity of segment point location pin; 4, second extremity of segment point location pin; 5, slip cap; 6, translation chi; 7, bearing pin; 8, evenly divided; 9, bolt.
The specific embodiment
Make the utility model with reference to accompanying drawing 1.Branch line drawing rulers such as this line segment; Constitute by first ruler 1 and second ruler 2; First ruler 1 is connected through bearing pin 7 with second ruler 2 to be fixed, and it is characterized in that: the free end of first ruler 1 and second ruler 2 is respectively equipped with first extremity of segment point location pin 3 and second extremity of segment point location pin 4, on second ruler 2, is provided with evenly divided 8; On second ruler 2, be provided with slip cap 5, be fixed with the translation chi 6 that is parallel to first ruler 1 through bolt 9 on the slip cap 5.
As the improvement of the utility model, described first ruler 1 and second ruler 2 are the transparent plastic chi; Described first extremity of segment point location pin 3 and second extremity of segment point location pin 4 are respectively perpendicular to the chi face of first ruler 1 and second ruler 2.
When using the utility model, first extremity of segment point location pin 3 and second extremity of segment point location pin 4 are separately fixed at the two ends of straight line, make translation chi 6 parallel and when pressing close to first ruler 1; It is fixing to tighten bolt 9, moves slip cap 5 this moment, and translation chi 6 can be along with slip cap 5 moves; Because second ruler 2 is provided with evenly divided 8; Can find very easily the line segment quantity of the five equilibrium of wanting, slip cap 5 is moved to the position of required five equilibrium, the intersection point of first ruler 1 and line segment is Along ent.
