The transparent airtight cavity of minor arc shape institute to the central angle size with the angular dimension at one of them angle of set -square equals. The set -square is the isosceles right -angle set -square, be equipped with an orthogonal angular bisector on the isosceles right -angle set -square plane, the transparent airtight cavity of minor arc shape institute be 90 degrees to the central angle size, its to the angular bisector of central angle and the orthogonal angular bisector of isosceles right -angle set -square coincidence, its be in to the centre of a circle of central angle on the orthogonal angular bisector of isosceles right -angle set -square.

Description

Novel set square

Technical field

Novel set square, belongs to stationery or realia field.

Background technology

Usually need to draw horizontal line, vertical curve, the line at certain inclination angle, the angle of certain angle in teaching.Current set square Sensation of lower edges or teacher of the horizontal line needs by blackboard to level is drawn, but often teacher can not accurately draw water very much Flat, vertical curve；Draw the line at certain inclination angle, certain angle angle can only it is existing 30 degree by set square, 45 degree, 60 degree, 75 Degree, 90 degree of angle, for the technique of painting at such angle is also required to by two set squares sometimes.Appoint to be drawn using a set square Meaning angle, while in order to allow set square that there is function of angle gauge, devising Novel set square.

The content of the invention

There is determined level, function that is vertical, drawing special angle to make set square, the technical scheme for implementing is as follows. Novel set square, including set square body, it is characterised in that：Set square plane is provided with the transparent closed cavity of minor arc shape；It is described Include liquid and bubble in transparent closed cavity；The set square plane for being provided with the transparent closed cavity of minor arc shape is provided with bad with described The adaptable uniform arcuate shape graduation mark of the transparent closed cavity of arc；The uniform arcuate shape graduation mark is transparent closed by the minor arc shape Cavity institute is to central angle decile.

The transparent closed cavity of the minor arc shape angular dimension to central angle size and the one of angle of the set square It is equal.

The set square is isosceles right angle triangle；The isosceles right angle triangle plane is provided with the angle at a right angle and puts down Separated time；The transparent closed cavity institute of the minor arc shape is 90 degree to central angle size, its to the angular bisector of central angle with it is described The angular bisector at isosceles right angle triangle right angle overlaps, its to the center of circle of central angle at the isosceles right angle triangle right angle On angular bisector.

The set square be provided with the one side of the transparent closed cavity of minor arc shape be additionally provided with it is another transparent closed with the minor arc shape The identical transparent closed cavity two of cavity；The cavity two is with the transparent closed cavity of the minor arc shape with regard to the minor arc shape The largest chord of transparent closed cavity arc is into being symmetrical arranged；Curved scale also is provided with surrounding's set square plane of the cavity two Line two.

The transparent closed cavity is separate with the cavity two, also has liquid and bubble in the cavity two.

The transparent closed cavity of the minor arc shape is connected with the conducting of the two ends of the cavity two.Can so make minor arc shape transparent close Close cavity and transparent closed cavity two and constitute linker, can so make bubble action on made triangle in closed cavity more Plus it is rapid sensitive, bubble can be also made around the new confined air being made up of the transparent closed cavity of minor arc shape and transparent closed cavity two Chamber is complete one week.

The cross section of the transparent closed cavity of the minor arc shape and cavity two is circular, rectangle or ellipse.

The circular half is inside set square；The oval major axis overlaps with set square plane.

Beneficial effect：Now the set square with protractor does not possess determined level and vertical function.By design, can There is the Novel set square and judge institute's setting-out whether level, function that is vertical, drawing specific angle.

Specific embodiment

Novel set square, including set square body（1）, it is characterised in that：It is transparent close that set square plane is provided with minor arc shape Close cavity（3）；The transparent closed cavity（3）It is interior including liquid and bubble；It is provided with the transparent closed cavity of minor arc shape（3）Triangle Plate plane is provided with the uniform arcuate shape graduation mark being adapted with the transparent closed cavity of the minor arc shape；The uniform arcuate shape graduation mark By the transparent closed cavity institute of the minor arc shape to central angle decile.

The set square is isosceles right angle triangle；The isosceles right angle triangle plane is provided with the angle at a right angle and puts down Separated time；The transparent closed cavity institute of the minor arc shape is 90 degree to central angle size, its to the angular bisector of central angle with it is described The angular bisector at isosceles right angle triangle right angle（2）Overlap, its it is straight in the isosceles right angle triangle to the center of circle of central angle The angular bisector at angle（2）On.

The set square is provided with the transparent closed cavity of minor arc shape（3）One side be additionally provided with it is another transparent close with the minor arc shape Close cavity（3）Identical transparent closed cavity two（4）；The cavity two（4）With the transparent closed cavity of the minor arc shape（3） With regard to the transparent closed cavity arc of the minor arc shape largest chord into being symmetrical arranged, such as Fig. 2；The cavity two（4）Around three Curved scale line two also is provided with gusset plane.Cavity two（4）Setting can more further expand the function of set square, such as may be used So that hypotenuse vertical plane to be placed the levelness situation that can measure inclined-plane.

The transparent closed cavity of the minor arc shape（3）With the cavity two（4）Two ends conducting connection.Minor arc shape can so be made Transparent closed cavity constitutes linker with transparent closed cavity two, can so make the bubble on made triangle in closed cavity Action is more rapid sensitive, can also make bubble around new with what transparent closed cavity two was constituted by the transparent closed cavity of minor arc shape Closed cavity is complete one week.
