Specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 6, a kind of multifunctional compass of the invention, including the compasses body 2 being made up of compasses leg 1, The compasses leg 1 includes the measurement leg 11 that can be combined with each other or dismantle and drafting leg 12, the measurement leg 11 Front is provided with the angle index line that surveying mapping angle is provided with for the length scale line 111 of surveying mapping length and the back side 112, the one side for drawing leg 12 is provided with the radius graduation mark 121 for surveying mapping radius, the measurement leg 11 The needle point 113 for fixing the drawing center of circle is provided with, the drafting leg 12 is provided with the pencil 122 for drawing.
Overturn traditional non-removable metal compasses, use can be combined with each other or the measurement leg 11 dismantled with draw The length scale line 111 for surveying mapping length is carved with leg 12, the front of measurement leg 11, and the reverse side for measuring leg 11 is carved There is the angle index line 112 for surveying mapping angle, drafting leg 12 is wherein simultaneously carved with half for surveying mapping radius Footpath graduation mark 121.When measurement leg 11 and drafting leg 12 combine to be used, according to the Dimension Types to be drawn and quarter Degree size carrys out rotation measuring leg 11 and draws leg 12, when both contact it is intersecting when can determine whether a point, this point is shown Scale value be exactly current measured value, then can be carried out the mapping operation of next step.When measurement leg 11 and drafting When the dismounting of leg 12 is used, measurement leg 11 becomes alone ruler, draws leg 12 and becomes pencil 122 alone, realizes pencil 122 With the drawing function of ruler.Multifunctional compass of the invention has merged various drawing instruments such as ruler, pencil 122, protractor Function, so as to avoid toggling for during drawing drawing instrument, reduces human error, improves and draws figure The efficiency and quality of paper.
As shown in Figures 1 to 5, the end of the measurement leg 11 of the present embodiment is provided with draw-in groove 114, the drafting leg 12 End be provided with the buckle 123 used cooperatively with draw-in groove 114, size and the size of buckle 123 of the draw-in groove 114 are mutually fitted Should.Specifically, using cooperatively using buckle 123 and draw-in groove 114, assembles simple and fast, firm and reliable connection, with screw glue The connected mode of material is compared, material-saving cost, long service life.
As shown in Figure 1, Figure 2 and Figure 3, the top of the buckle 123 of the present embodiment is provided with the pencil for Telescopic pencil 122 Button 124, the buckle 123 is rotated around the Pencil button 124.Specifically, the Pencil button for being provided with circle of buckle 123 124, press the Pencil button 124 and stretch out pencil 122 to use, the Pencil button 124 is depressed multiple times and can control the length that pencil 122 stretches out Degree, pinning the Pencil button 124 and do not put can shorten the length that pencil 122 stretches out, it is easy to control, easy to use.Due to the energy of buckle 123 It is enough to be rotated around the Pencil button 124, measurement leg 11 just can be realized when buckle 123 is combined with draw-in groove 114 and leg is drawn 12 multi-angle rotaries are adjusted, and meet the drawing requirements of different angle combinations.
As shown in Fig. 1, Fig. 4 and Fig. 6, the measurement leg 11 of the present embodiment is made up of stainless steel.Specifically, with stainless The measurement leg 11 that steel matter is made, making, material-saving, reduces cost, to environment are integrally formed using all steel material Strong adaptability, corrosion-and high-temp-resistant is convenient for cleaning, is also beneficial to the accurate scale value read on measurement leg 11, and in reality Protrude attractive in appearance and elegance again on the basis of.
As shown in Figure 1, Figure 2 and Figure 3, the drafting leg 12 of the present embodiment is made up of plastic material.Specifically, with plastics material The drafting leg 12 that matter is made, plastic material is soft, flexible to be hardly damaged, long service life.
As shown in Figure 1, Figure 2 and Figure 4, the measurement leg 11 of the present embodiment presents width with the exterior contour for drawing leg 12 Under narrow structure.Specifically, the structure wide at the top and narrow at the bottom is easy to hand to grasp, easy to use.
As shown in Figure 1, Figure 2 and Figure 4, the measurement leg 11 of the present embodiment and the head end for drawing leg 12 be it is circular and The both sides of main body are continuity and are gradually drawn close to middle part.Specifically, measurement leg 11 is designed to similar with drafting leg 12 Pin shape, makes center of gravity be located on leg, by rotating the circular head end of leg come graphing, not only rotate it is smooth but also The line weight drawn out is uniform.
As shown in Figure 1, Figure 2 with shown in Fig. 6, the angle index line 112 of the present embodiment and the scale value of radius graduation mark 121 with Unequal distance is horizontally disposed with.Specifically, made with drawing leg 12 and contact intersect different degrees of according to measurement leg 11 Make angle index value and radius scale value that spacing differs, design science rationally, realize compasses of the invention meet ruler with The drawing function of protractor, meets various drawing requirements to greatest extent.
As shown in Figure 1 and Figure 4, the scale value of the length scale line 111 of the present embodiment is horizontally disposed with equal distance. Specifically, the length scale value that measurement leg 11 is uniformly arranged can be used as ruler, met measurement leg 11 and drawn leg 12 are applied in combination or dismantle the functional need for using.
As shown in figure 1, the intersection point that the measurement leg 11 of the present embodiment is intersected with drafting leg 12 by rotation is to be seen Examine the scale value of display.Specifically, according to the geometrical principle of mathematics, two intersecting straight lines can determine that a point.Measurement leg 11 intersect the point for determining and are current scale value with leg 12 is drawn by mutually rotation, it is easy to observe, be easy to draw.
Understand that the present invention is, with above-described good characteristic, to be able to make it using upper in sum, promote conventional The efficiency that does not have in technology and there is practicality, the product as a great practical value.
Above content is only presently preferred embodiments of the present invention, for one of ordinary skill in the art, according to of the invention Thought, will change in specific embodiments and applications, and this specification content should not be construed as to the present invention Limitation.
