Abstract
The invention relates to a multifunctional ruler for teaching. The multifunctional ruler comprises a left supporting rod and a right supporting rod. A chalk sleeve is arranged at the lower end of the left supporting rod. A supporting point is arranged at the lower end of the right supporting rod. The upper end of the left supporting rod and the upper end of the right supporting rod are rotatably arranged on a connecting block. Angle scales are arranged on the surface of the connecting block, and a vertical sliding groove is formed in the position, between the left supporting rod and the right supporting rod, in the connecting block. A movable block is arranged in the sliding groove. Scales are arranged in the surface of the left supporting rod and the surface of the right supporting rod respectively, and index lines used in cooperation with the angle scales on the surface of the connecting block are arranged at the upper end of the left supporting rod and the upper end of the right supporting rod respectively. Rotatable adjusting rods are arranged in the positions, in the connecting block, of the left supporting rod and the right supporting rod respectively. The other ends of the two adjusting rods are arranged on the movable block. The multifunctional ruler can be used for drawing circles, can be used as a straight ruler, a right angle ruler and a protractor, and is simple in structure and convenient to use.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1-4 is Multifunctional ruler for teaching of the present invention, comprises left support bar 1 and right support bar 2; The side of described left support bar 1 lower end is provided with chalk sleeve 11, for installing chalk; The side of described right support bar 2 lower end is provided with the strong point 21 be made up of elastomeric material, increases the frictional force between blackboard, and preventing picture bowlder from sliding affects precision; The upper end of described left support bar 1 and right support bar 2 is rotating to be respectively arranged on contiguous block 3, and the side near the strong point 21 on the side of chalk sleeve 11 and right support bar 2 on left support bar 1 is oppositely arranged, and can draw the circle that diameter is less; The surface of described contiguous block 3 is provided with angle index, and the inner centre at left support bar 1 and right support bar 2 is provided with the chute 31 vertically arranged; Be provided with in described chute 31 to be made up of elastomeric material and with the movable block 5 of chute 31 interference fits; The surface of described left support bar 1 and right support bar 2 is respectively arranged with scale, and upper end is respectively arranged with index wire, by with the angle index on contiguous block 3 surface with the use of, directly can read angle value; Described left support bar 1 and right support bar 2 are respectively arranged with rotating adjusting rod 4 in contiguous block 3; The other end of two described adjusting rods 4 is separately positioned on movable block 5; During work, slided in chute 31 by movable block 5, described left support bar 1 and right support bar 2 are rotated around contiguous block 3 simultaneously.
During use: due to movable block 5 to be made up of elastomeric material and with chute 31 interference fits, movable block 5 can chute 31 in a generation coupling mechanism force;
When compasses use: overcome coupling mechanism force and left support bar 1 and right support bar 2 are rotated around contiguous block 3, adjustment radius value, just can draw circle by the chalk sleeve 11 of left support bar 1 lower end and the strong point 21 of right support bar 2 lower end.
When chi uses: as shown in Figure 5, overcome coupling mechanism force left support bar 1 and right support bar 2 are outwards rotated around contiguous block 3, the lateral surface making left support bar 1 and right support bar 2 at grade, utilizes the scale on left support bar 1 and right support bar 2 surface when ruler use.
When protractor uses: as shown in Figure 6, overcome coupling mechanism force left support bar 1 and right support bar 2 are rotated around contiguous block 3, overlapped with measured limit by the lateral surface of left support bar 1 and right support bar 2, utilize the angle index on index wire and contiguous block 3 surface with the use of, directly can read angle value.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Multifunctional ruler for teaching of the present invention can draw circle, can use again as ruler, square and angle square, and structure is simple, easy to use.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
