Description

Combined template

The utility model belongs to a kind of drawing appliance, particularly integrates the multi-functional combination rule of functions such as set square, compasses, protractor, T-square.

Drawing appliance function singlenesses such as existing set square, compasses, protractor, angle square can only be used separately, therefore, inconvenience is carried in use, particularly when glass plate or metallic plate upper drawing circle, compass foot can't be drawn circle owing to not inserting fixedly centre point of glass or metal.Applicant of the present utility model once proposed a kind of multipurpose plotter that integrates set square, compasses, protractor, angle square in its 90211013.6 patent application, this instrument is made of main shaft, valve rubber, compass foot, angulation pin, slip chi, flexible connection chi, though have above-mentioned functions and characteristics, but product structure design complexity, protractor is an isosceles triangle, is provided with circular arc line, general indigestion, particularly the pupil is difficult to understand and understand, and uses also trouble.

The purpose of this utility model be to avoid above-mentioned the deficiencies in the prior art part and provide a kind of design science, simple in structure, easy to manufacture, use and to carry conveniently, have the multiduty combination rule of functions such as set square, compasses, protractor, T-square.

Solution of the present utility model is: combination rule are made of main scale and adjustable rule, one of its main scale is rectified face the secured adjusted screw is housed, have the isosceles right triangle locating slot, the centre is provided with folded sheet and special triangle fixing point, the unfolded plate is protractor, the other end of main scale is equipped with movable compasses tiptoe, one end of adjustable rule is provided with Connection Card, U type yoke is equipped with in the front, the back side is established all and is pasted the inclined-plane, the other end of adjustable rule indicates protractor central point and special triangle fixing point, and pencil or chalk hole are equipped with in the top.

Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is combination rule main scale and adjustable rule structure chart;

Fig. 2 is the protractor schematic diagram of folded sheet after launching;

Fig. 3 is movable compasses tiptoe structure chart;

Set square schematic diagram when Fig. 4 is use;

Compasses schematic diagram when Fig. 5 is use;

Protractor schematic diagram when Fig. 6 is use;

T-square schematic diagram when Fig. 7 is use.

Fig. 1, main scale 1 among Fig. 2 can be by lucite with adjustable rule 9, transparent plastic, plank or thin sheet metal process, one of main scale 1 is rectified face secured adjusted screw 2 is housed, have the isosceles right triangle locating slot 3 that connects adjustable rule 9, the centre is provided with movable folded sheet 4, folded sheet 4 is marked with right angled triangle, isosceles right triangle fixing point 5, fixing point 6, unfolded plate 4 is protractor 7, be carved with the acute angle number of division of 0 to 90 degree on the camber line of protractor 7, be carved with the obtuse angle number of division of 90 to 180 degree on the string of a musical instrument, the other end of main scale 1 is equipped with rotatable movable compasses tiptoe 8, one end of adjustable rule 9 is provided with Connection Card 10, U type metal yoke 11 is equipped with in the front, the back side is established all and is pasted inclined-plane 12, the other end front of adjustable rule indicates protractor central point 13 and special triangle fixing point 14, and pencil or chalk hole 15 are equipped with in the top.

The movable compasses tiptoe of describing among Fig. 38 is made up of iron pipe nail 16, sponge 17, steel ball ball 18.

During use, the U type metal yoke 11 of adjustable rule 9 is inserted in the lead screw of set screw 2 of main scale, make the Connection Card 10 of adjustable rule 9 be close to the edge of main scale, tighten the screws 2, promptly constitute the right angle triangle of a no hypotenuse as shown in Figure 4, can make right angled triangle at any angle, connect triangle fixing point 5,14 and 6,14 two points respectively, be right angled triangle and right angled isosceles triangle.

Main scale 1 and adjustable rule 9 is positive relative, and the U type yoke 11 of adjustable rule 9 is inserted in the screw rod of set screw 2 of main scale 1, tightens set screw 2, promptly constitutes compasses as shown in Figure 5.These compasses can be drawn circle arbitrarily because tiptoe is equipped with sponge 17 and does not slide on glass plate, steel plate, plank, speed is fast, and is effective, but should notice that main scale 1 is vertical with the plane, adjustable rule 9 and plane oblique.

The U type yoke 11 of adjustable rule 9 is inserted in the screw rod of set screw 2 of main scale 1, Connection Card 10 embeds in the triangle locating slot 3, the tight main scale edge that reclines is cut on inclined-plane 12, tighten set screw 2, unfolded plate 4, promptly constitute a protractor as shown in Figure 6, during the amount acute angle, protractor central point 13 on the adjustable rule 9 is alignd with a limit of institute angulation along the inner edge of adjustable rule, and from left to right, the reading of another of angle limit indication is exactly the angle at this angle, during the amount obtuse angle, right outer edge from protractor central point 13 along adjustable rule aligns with a limit of institute's angulation, and from right to left, the reading of another of angle limit indication is exactly the angle at this angle.

U type yoke 11 on the adjustable rule 9 is placed on the front or the optional position, the back side of main scale 1, the end face of Connection Card 10 is near the edge of main scale 1, just constitute an adjustable head t-square as shown in Figure 7, can make vertical line and parallel lines, when making parallel lines, adjustable rule 9 just can be made parallel lines along the sideline move left and right of main scale 1.

This combination rule can be processed into large, medium and small three types, and are large-scale for all kinds of school instruction usefulness, and medium-sized for project planner's usefulness of drawing, small-sized drawing for students in middle and primary schools' operation used.
