Abstract

The utility model discloses a multifunctional mathematical ruler, which is composed of a fixed ruler 1, a rotation ruler 3, a translation ruler 10 and a movable pen sleeve frame 6. The rotation ruler 3 comprises a rotation straight ruler 13 and a semi-protractor 5, and the movable pen sleeve frame 6 is arranged on the rotation straight ruler 13. The rotation ruler 3 and the fixed ruler 1 penetrate through a circular hole 8 having a wire port through an adjusting screw 4, and then are screwed to integration. The translation ruler 10 is clamped and sheathed on the rotation straight ruler 13. The multifunction mathematical ruler is the composite unit of the ruler, compasses and the protractor, and has the advantages of simple operation and convenient and quick drawing.

Description

Multifunctional mathmatical ruler

The utility model relates to the mathmatical ruler tool of a kind of multifunctional assembled suitable teaching, research and production field drawing usefulness.

Mostly existing mathmatical ruler tool is to divide and independent the use, as ruler, protractor, compasses etc., carry inconvenience on the one hand, using also inconveniently on the other hand in some aspects, during described point curve plotting figure, is to utilize right angle triangle to determine the abscissa of point in plane right-angle coordinate for example, determine ordinate again, could determine the position of this point after finishing this two step, not only not directly perceived, and than bothering.

The purpose of this utility model is to overcome the shortcoming of existing mathmatical ruler tool, provides a kind of ruler, protractor, compasses of collecting to be the multifunctional mathmatical ruler of one, and is easy to carry, uses simply, can draw quickly and easily.

For achieving the above object, the solution that the utility model adopts is: this multifunctional mathmatical ruler, by fixedly ruler, rotation chi, translation ruler are formed, fixedly be provided with the protractor pointer and be with a circular hole of mouth on the ruler, the rotation chi then is made up of ruler and half protractor, the rotation chi by regulating degree of tightness screw and fixedly ruler kink and be one, and the screw that can regulate degree of tightness is the axle rotation, the translation ruler passes through several latches perpendicular to the rotation chi, cover is stuck on the rotation chi, partly offers slotted eye at the ruler of rotation chi in addition one movable pen cap frame is set.

Owing to adopted said structure, when fixedly ruler and rotation chi are vertical, just constituted the horizontal longitudinal axis of rectangular coordinate system, utilize the translation ruler can determine a little horizontal ordinate again, that is determined the position of putting once the step, utilize this chi described point drawing convenient and swift.Rotation rotation chi utilizes half protractor that rotates on the chi can measure the number of degrees of quadrant angle easily; Utilization activity pen cap frame inserts trepanning with pencil or chalk, and ruler is the center of circle with the screw that rotates chi to kink fixedly, the arc or the circle of any major radius that can draw.So this multifunctional mathmatical ruler is the assembly of ruler, protractor, compasses, the many usefulness of a chi, it is convenient and swift to draw.

Below in conjunction with the drawings and specific embodiments the utility model is done and to be described in further detail.

Fig. 1 is the floor map of multifunctional mathmatical ruler

Fig. 2 is the fixing schematic diagram of ruler

Fig. 3 is the schematic diagram of rotation chi

Fig. 4 is the schematic diagram of translation ruler

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, multifunctional mathmatical ruler is by fixedly ruler 1, rotation chi 3, translation ruler 10 are formed.Fixedly ruler 1 is provided with protractor pointer 2 and has a circular hole 8 of mouth; Rotation chi 3 is made up of ruler 13 and half protractor 5, offers a rectangle slotted eye 12 on ruler 13, has installed a movable pen cap frame 6 that moves up and down along rectangle slotted eye 12 by the screw 7 of adjusting degree of tightness on slotted eye 12, has offered pen cap hole 9 on the stock 6; Rotation chi 3 and fixedly ruler 1 pass circular hole 8 by the screw 4 that can regulate degree of tightness and kink and be one, rotation chi 3 can screw 4 be the axle rotation, this moment half protractor in company with rotating together, can be easy to measure the number of degrees of quadrant angle according to the index of protractor pointer 2.When needs picture circle or arc, at first move movable pen cap frame 6 by set screw 7, determine radius length, then pencil or chalk are inserted the stock hole 9 of stock 6, with set screw nail 4 is the center of circle, and hand-held pencil or chalk rotate rotation chi 3 can draw required circle or arc.When needs are determined the position of plane right-angle coordinate mid point, making fixedly, ruler 1 keeps vertical with rotation ruler 3, the horizontal axis of ordinates that is equivalent to rectangular coordinate system, with translation ruler 10 by latch 11 vertically overlap be stuck in the rotation ruler 13 on since translation ruler 10 perpendicular to the rotation ruler 13, promptly be parallel to axis of abscissas, the abscissa of reading on its chi that is point, upper and lower translation moves the ordinate that ruler 10 is determined point, promptly once going on foot the coordinate that can determine a little, has also just determined the position of point.
