Abstract
The utility model discloses a ruler for equally dividing a segment, which comprises a T-square (1). A straight ruler of the T-square (1) is provided with a slide (2), a plurality of equal-length straight rulers (3) are connected pairwise through hinges (4), the hinges (4) in odd number are arranged in the slide (2) of the straight ruler of the T-square (1) from left to right, and the hinges (4) arranged in the slide (2) are provided with alignment pins (5), and the left end of each straight ruler (3) is arranged on the T-square (1) through a rivet and aligned to the zero position of the T-square (1). By means of the structure, convenience in use and time and labor saving are realized.
Description
Technical field
The utility model relates to a kind of mathematics teaching aid, relates in particular to branches such as a kind of line segment and uses chi.
Background technology
At present branch line segment such as mathematics all adopts and line segment is calculated the back points out on blackboard with ruler and carry out five equilibrium, and not seeing has the use teaching aid to come the five equilibrium line segment, has so not only wasted a large amount of instructional blocks of times, has also increased teacher's labour intensity.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, and is easy to use, saves time, and time saving and energy saving mathematics is used chi with branches such as line segments.
The technical scheme of the utility model is that branches such as a kind of line segment are used chi; It comprises T-square 1; It is characterized in that: on the ruler of said T-square 1, be provided with chute 2, some isometric rulers 3 connect through hinge 4 in twos, and odd number hinge 4 is arranged in the chute 2 of said T-square 1 ruler from left to right; The hinge 4 that is arranged in the said chute 2 is provided with contraposition pin 5, and the left end of said ruler 3 is arranged on the said T-square 1 and with the zero-bit of said T-square 1 through rivet and aligns.
The technical scheme of the utility model is provided with groove 6 at the middle part of said contraposition pin 5 in addition.
The beneficial effect of the utility model is through on the ruler of said T-square 1, being provided with chute 2, and some isometric rulers 3 connect through hinge 4 in twos, and odd number hinge 4 is arranged in the chute 2 of said T-square 1 ruler from left to right; The hinge 4 that is arranged in the said chute 2 is provided with contraposition pin 5; The left end of said ruler 3 is arranged on the said T-square 1 and with the zero-bit of said T-square 1 through rivet and aligns, during use, with the zero-bit of T-square 1 and the left justify of line segment; The ruler 3 that will connect in twos with hand stretches to the right; Confirm that according to the isodisperse of line segment which hinge 4 aligns with the other end of line segment, the two ends of line segment are exactly the Along ent of this line segment with the hinge 4 residing positions between wherein after hinge 4 aligns, because hinge 4 is provided with contraposition pin 5 and is provided with groove 6 in the middle; Mark each Along ent easily with pen; Realized easy to usely, saved time effect of saving time and labor.
