Abstract

The utility model discloses a multifunctional ruler which comprises a main ruler and an auxiliary ruler. Through-holes are formed at the end parts of both the main ruler and the auxiliary ruler; the main ruler and the auxiliary ruler are in shaft connection through a rotating shaft matched with the through-holes; and an angle measuring plate is mounted on the rotating shaft. The utility model has the advantages that the main ruler and the auxiliary ruler are in shaft connection through the rotating shaft, so that when the main ruler and the auxiliary ruler are folded, a common ruler is obtained, and when the main ruler and the auxiliary ruler are separated from each other to form a certain angle, a set square is obtained for drawing a specific angle; a graduation line pointing to the center of the angle measuring plate is arranged on one side of a strip-shaped hollow slot on the auxiliary ruler so as to confirm the angle readouts, and also the graduation line can be used to measure the degree of an unknown angle; a concave hole is formed on one side of the strip-shaped hollow slot near to the graduation line, so that a user can fix a pen point in the concave hole and rotate the auxiliary ruler to draw a circle; and the concave hole and the readout of the graduation line of the auxiliary ruler correspond to each other, so that the user can quickly determine the radius of the circle, and does not need to measure with a ruler again.

The utility model content

Technical problem to be solved in the utility model is the present situation at prior art, and a kind of multifunctional ruler simple in structure, easy to use is provided, and has ruler, set square, protractor and compasses function concurrently.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: multifunctional ruler, comprise main scale and auxilliary chi, main scale and auxilliary ruler end part are shaped on through hole respectively, main scale and auxilliary chi by the rotating shaft that matches with through hole mutually axle be connected, the angulation dish is installed in the rotating shaft.

For optimizing technique scheme, the measure of taking also comprises:

Have the bar shaped dead slot on the above-mentioned auxilliary chi, bar shaped dead slot and auxilliary chi keeping parallelism, and be shaped on the graduation mark that points to the angulation dish center of circle on the side.On the angulation dish, be shaped on the graduation mark of level, bar shaped dead slot one side is shaped on the graduation mark that points to the angulation dish center of circle, when needs take measurement of an angle, as long as the graduation mark of level is alignd with the base of measured angular, rotate auxilliary chi then, the graduation mark on the auxilliary chi is alignd with the another side of measured angular, just can record angle accurately, easy to use, accuracy of reading.

The side that above-mentioned bar shaped dead slot is positioned at graduation mark is shaped on shrinkage pool, the corresponding setting of millimeter graduation mark on shrinkage pool and the auxilliary chi.The side that the bar shaped dead slot is positioned at graduation mark is shaped on shrinkage pool, and the user can be fixed in nib in the shrinkage pool, rotates auxilliary chi then, the circle of just drawing; Shrinkage pool is corresponding with the graduation mark reading of auxilliary chi, can allow the user determine radius of a circle fast, need not to re-use ruler and measures again.

Compared with prior art, multifunctional ruler of the present utility model comprises main scale and auxilliary chi, and main scale and auxilliary ruler end part are shaped on through hole respectively, main scale and auxilliary chi by the rotating shaft that matches with through hole mutually axle be connected, the angulation dish is installed in the rotating shaft.Advantage of the present utility model be main scale and auxilliary chi by rotating shaft mutually axle connect, when main scale merges with auxilliary chi, can be as common ruler use; Main scale and auxilliary chi separate when forming certain angle, can use as set square, and the specific angle of drawing, bar shaped dead slot one side on the auxilliary chi is shaped on the graduation mark that points to the angulation dish center of circle, can determine the reading at unknown angle; Simultaneously also can utilize graduation mark that the angle at unknown angle is measured; The side that the bar shaped dead slot is positioned at graduation mark is shaped on shrinkage pool, and the user can be fixed in nib in the shrinkage pool, rotates auxilliary chi then, the circle of just drawing; Shrinkage pool is corresponding with the graduation mark reading of auxilliary chi, can allow the user determine radius of a circle fast, need not to re-use ruler and measures again.
