Abstract

The utility model discloses a common multifuncitonal measuring instrument whose type and amount can be changed. Three straight rulers are combined with a protractor to form the common multifuncitonal measuring instrument. Two straight rules of the three straight rulers are provided with trackways. The common multifuncitonal measuring instrument has all the functions of a triangular plate, a protractor, a straight ruler, compasses and a beam divider and the function displayed when a triangular plate, a protractor, a straight ruler, compasses and a beam divider are matched. When the common multifuncitonal measuring instrument is used, the varying relation of type and amount in a figure can be visually observed. The common multifuncitonal measuring instrument can be widely used by students, teachers and workers who generally draw figures.

Description

Common multifuncitonal measuring instrument

The utility model is the invention about the measurer structure.A kind of plain edition multifunctional measuring tool that is suitable for student and general mapping use.

Current known ordinary measring tool, all adopt traditional finalizing the design with particular value, because existing measurer is all fixing on type and amount, and in the reality mapping, the fixedly figure effect of particular value is little, and the measurer of the existing typing of a lot of situations can not independently be finished, and has only with several to cooperate repeated use, this does not satisfy the requirement of actual mapping to using and carrying all and make troubles.

Task of the present utility model is: provide a kind of and can have student mapping and the required function of general mapping, and type and amount can both be in than applicable scope continually varying plain edition measurer.

The scheme of its solution is: with three rulers, wherein two belt tracks effectively are connected with protractor again.They can both be changed on type and amount mutually.

The utlity model has existing with set square, ruler, protractor, compasses, divider repertoire and they make up the function that demonstrates mutually and can observe the situation of change of shape and amount intuitively by the utility model, help thinking.

The worker that the utility model can extensively be fit to student, teacher and general mapping uses.

Accompanying drawing has been described an embodiment of the present utility model, and accompanying drawing 1 is a general lay-out of the present utility model, and accompanying drawing 2 is that the utility model structure is separated audio-visual picture.

As shown in Figure 2: the ruler (2) of unoccupied orbital forms a fixed connection with protractor (1) in the band, the ruler of trough of belt (3) is by being engaged in the rotating shaft (5) and ruler (2) combination in the interior unoccupied orbital of ruler (2), like this, ruler (3) is (5) rotation around the shaft both, can move up and down along ruler (2) with rotating shaft (5) again, ruler (4) is by being installed in the turning point (8) and ruler (3) combination in ruler (3) groove, and it was both rotatable, can move up and down along groove with turning point (8) again.

From accompanying drawing 1 as seen: ruler (3) can change 180 ° along protractor by rotating shaft (5).For this reason, the function that has had ruler, protractor and their cooperation mappings; When ruler (3) forwards maximum limit angle (180 °) to, be in line on same plane with ruler (2), can enlarge the ruler range; Ruler (3) when the interior unoccupied orbital by rotating shaft (5) and ruler (2) along ruler (2) when moving up and down, have the function that ruler, protractor, set square cooperate mapping; Ruler (4) moves up and down along the chute of ruler (3), can intersect with ruler (2), (3).Have angle, limit at this and change the function that constitutes arbitrary triangle, if insert iron nail or pencil-lead in the aperture (6) of ruler (2), (3) lower end, (7), turn-off left bottom ruler (4) is moved on to is measured required separation distance between bipod.Has the function of compasses or divider this moment.

Claims

A kind of student who is made of ruler, protractor uses the plain edition multifunctional measuring tool, it is characterized in that: ruler (3) is connected by rotating shaft (5) with ruler (2) and protractor, ruler (3) can rotate 180 ° along protractor by rotating shaft (5), when ruler (3) forwards 180 ° at maximum limit angle to, be in line on same plane with ruler (2); There is interior unoccupied orbital can supply ruler (3), ruler (4) to move therein on ruler (2), the ruler (3); Ruler (2), ruler (3) lower end have aperture (6), (7) that can insert iron nail or pencil-lead.
