Abstract
The utility model relates to a cultural article, particularly a convenient multi-purpose semi-circle instrument which uses a common semi-circle instrument and a ruler as the main structure. The common semi-circle instrument and the ruler are connected and matched. The utility model has the functions of a common semi-circle instrument and a ruler. The utility model can also be used for directly drawing various angles and various arcs. The utility model has the advantages of simple structure, convenient usage and low cost. The utility model suitable for new requirements for stationery for students, teachers and engineering personnel.
Description
The utility model relates to a kind of cultural goods, and is particularly a kind of through improved convenient multi-purpose graphometer.
At present, common graphometer is many to be made of a semicircle ruler, and main effect is to take measurement of an angle, at an angle the angle of can't directly drawing, the arc of the certain radius of also can't drawing.
The purpose of this utility model is to provide a kind of convenient multi-purpose graphometer, and it can not only take measurement of an angle as common graphometer, simultaneously, can also directly draw into the angle of various angles and the arc of multiple radius, thereby satisfies people's multiple needs easily.
The utility model graphometer with a common graphometer and ruler as basic building block, wherein, graphometer has a plurality of kinds, can be that learning teaching is used, also can be that engineering is used, can be solid, preferably hollow, the length of another member ruler is corresponding with the graphometer diameter, on ruler, process a straight line parallel and well-regulated a plurality of aperture, between connector and graphometer and ruler, flexible member will be housed, so that the two has certain frictional force with the ruler edge, all be processed with centre bore in graphometer and the ruler in the heart, pass centre bore with an axle the two is coupled together, these two can be relatively rotated, thereby not only play the effect of common graphometer and can directly draw various angles and multiple arc.
The utility model simple structure, easy to use, purposes is various, can be widely used in student's study and teachers ' teaching and Graphing of Engineering.
1 couple of embodiment of the present utility model is described further below in conjunction with accompanying drawing.
Fig. 1 is the schematic top plan view of an embodiment of the utility model.
With reference to the accompanying drawings 1, the utility model is made up of graphometer (1), ruler (2), connector (3), flexible member (4).Wherein, graphometer (1) is the hollow graphometer of common plastics, ruler (2) be plastics and be the ruler at zero point with the center.On ruler (2), scale is arranged and be carved with a straight line (5) by the center of circle, be used for aiming at scale, the a plurality of apertures (6) that are processed with arranged askew on ruler (2) can be used for the picture arc, in graphometer (1) and ruler (2), be processed with centre bore in the heart, be used for passing connector (3).Connector (3) can be a metal, also can be plastics, transparent, can rivet, also can be threaded, can be solid, preferably hollow, its role is to the centre bore by ruler (2) and graphometer (1), the two couples together them, and allows them to relatively rotate.Flexible member (4) is made by the phosphorus bronze sheet punching press, and middle porose, connected piece (3) compresses it, to keep the frictional force between graphometer (1) and ruler (2), makes the utility model have stability in use.When using the utility model, rotate ruler and the center line (5) of its ruler (2) is aimed at the desired number of degrees on the graphometer, the angled angle of can drawing along the edge of ruler (2) and graphometer (1), in the aperture (6) that nib is inserted on the ruler (2), the arc of the certain radius of can drawing, meanwhile the utility model can also use as general graphometer and ruler.
Claims (5)
1, a kind of convenient multi-purpose graphometer is characterized in that being assembled by common graphometer (1), ruler (2), connector (3), flexible member (4).
2, convenient multi-purpose graphometer according to claim 1 is characterized in that graphometer (1) can be solid, also can be hollow and be processed with centre bore on its center of circle.
3, convenient multi-purpose graphometer according to claim 1 is characterized in that being processed with centre bore on the ruler (2), is carved with a straight line by the center (5) and is processed with a plurality of apertures (6) that rule is arranged.
4, convenient multi-purpose graphometer according to claim 1 is characterized in that connector (3) can be a metal, also can be plastics, can be solid, also can be hollow, can be the riveted joint, hot pressing, also can be threaded, when being solid, preferably transparent.
5, convenient multi-purpose graphometer according to claim 1 is characterized in that flexible member (4) made by elastic material, and processes porose thereon.
