Abstract
The utility model relates to a combined angle protractor. A straight bottom edge of a known semi-circular protractor is assembled with an auxiliary plate which can be one or a plurality of angle protractors, set squares, rulers, etc. the utility model can be used for drawing circles and angles, measuring angles, length, the angular dimensions of objects, etc., and has the advantages of simple structure and convenient assembly.
Description
The utility model relates to a kind of multifunction combined protractor.
Existing angle square function singleness is drawn all inconveniences of angle, angulation with it, especially is difficult to measure angle in kind.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of simple in structure, and combined and instant can be measured angle in kind, has the combined type protractor of multiple function.
The purpose of this utility model can reach by following measure:
A kind of multifunction combined protractor comprises that circumferential edge 2 is provided with the semicircle Angle protractor 1 of angle measuring calibration 3, and its special character is, is equipped with on the straight base 8 of described Angle protractor 1 and can makes the accessory plate 11 that circumference rotates.
Accessory plate 11 of the present utility model also can be assemblied on the Angle protractor 1 by the slotted eye 12 that can cooperate with Angle protractor 1 straight base 8 epirelief axles 10 on it.
Accessory plate 11 of the present utility model also can be assemblied on the Angle protractor 1 by the protruding axle 13 that can cooperate with slotted eye 4 on the Angle protractor 1 straight base 8 on it.
Accessory plate 11 of the present utility model also can cooperate by the slotted eye 12 on slotted eye 4, the accessory plate 11 on bearing pin 14 and the Angle protractor 1 straight base 8 and is assemblied on the Angle protractor 1.
The insertion end of bearing pin 14 of the present utility model can be cone-shaped.
Accessory plate 11 of the present utility model can be semicircle Angle protractor, ruler or set square; Described slotted eye 4 and slotted eye 12 are open-work, blind hole or shallow grooves.
Protruding axle 10 on the Angle protractor 1 of the present utility model can be located at the central point 7 or the two ends on its straight base 8, and the slotted eye 4 on the described Angle protractor 1 is located at central point 7, the both sides on its straight base 8 or is distributed on its straight base 8; Center or edge that protruding axle 13 on the described accessory plate 11, slotted eye 12 are located at its straight flange respectively.
The accompanying drawing drawing is described as follows:
Fig. 1 is the structural representation of the utility model Angle protractor.
Fig. 2 is the structural representation of the utility model embodiment one.
Fig. 3 is the structural representation of the utility model embodiment two.
Fig. 4 is the structural representation of the utility model embodiment three.
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, the angle measuring calibration 3 that is provided with on the circumferential edge 2 of the utility model semicircle Angle protractor 1 is mainly used in measuring angle, the length scale 6 of 180 ° of bottom lines 5 and amount length can be set on its straight base 8, also be provided with slotted eye 4 or protruding axle 10 on its straight base 8, slotted eye 4 can be arranged at central point 7, the two ends on straight base 8 or be distributed on the straight base 8.When slotted eye 4 is distributed on the straight base 8, can be corresponding with length scale 6 on it by certain-length, with slotted eye 4 double as scale mark holes 9, be 0.5 centimetre, 1 centimetre etc. as, the spacing that makes slotted eye 4.The protruding axle 10 of Angle protractor 1 can be arranged at the central point 7 or the two ends on its straight base 8.Referring to Fig. 2, accessory plate 11 can be the semicircle Angle protractor, its straight base be provided with Angle protractor 1 on slotted eye 4 or 10 assemblings of protruding axle, the slotted eye 12 that cooperates or protruding 13.Present embodiment is to cooperate by the penetrating slotted eye of bearing pin 14 with Angle protractor 1 and accessory plate 11 central spot, and both are assembled together, when the insertion end of bearing pin 14 was cone-shaped, maintenance when easy to use also can be assembled together the termination on two straight bases of Angle protractor in the present embodiment.Accessory plate 11 shown in Figure 3 is a ruler, one end on ruler one end and Angle protractor 1 straight base 8 is assembled together, it also can be assemblied on the protruding axle 10 of the one of slotted eye 4 uniform on the Angle protractor 1 straight base 8 or central point, accessory plate 11 can be a plurality of, accessory plate 11 among Fig. 4 is by Angle protractor 15, set square 16,18 form, the one end mount on one end on Angle protractor 15 straight bases and the straight base 8 of Angle protractor 1, the other end on both straight bases respectively with set square 16, one jiao of mount of 18, adjust two Angle protractors and two set squares when measuring material object, can obtain full size, as, the distance among Fig. 4 between two set square bases is exactly a length dimension in kind.The utility model can adopt materials such as plastics, organic glass, also the handwriting practicing groove can be set on the plate face of Angle protractor.
The utility model compared with prior art has following advantage:
Simple in structure, combined and instant, function is many, cost is low, one-object-many-purposes, can be used for angulation, the amount length, Handwriting practicing, amount material object etc.
