Abstract
The present invention discloses a novel compasses ruler. The compasses ruler is a ruler of transparent sheet and with regularly distributed small holes, which may be matched with two pens to draw circle. The compasses ruler has the functions of both ruler and compasses, and compared with common compasses, the present invention has low cost and convenient use.
Description
Technical field
The invention belongs to compasses and ruler in the drafting instrument, the present invention mainly introduces the compasses chi that a kind of newly-designed compasses and this compasses and ruler are combined into together.
Background technology
Compasses are common drafting instruments, but the compasses that people use always all are the bifoot type compasses, the centering of one pin, and a pin is drawn circle.
Summary of the invention
The purpose of this invention is to provide a kind of futuramic compasses, and with this compasses by pasting or some other means make it merge with ruler to become the compasses chi, make it can work as ruler usefulness, can work as compasses again and be used for picture and justify.
Adopt following technical scheme for reaching the present invention of this purpose: 70 millimeters of block lengths, wide 30 millimeters rectangle thin transparent plastic plate, the line segment point midway of doing one 60 millimeters long in plastic plate central authorities are made a call to a diameter less than 1 millimeter circular hole, and this hole is a circle center hole.The left end of circle center hole is made a call to 15 diameters left less than 1 millimeter hole successively successively 2 millimeters of distance circle center holes, 4 millimeters, 6 millimeters to 30 millimeters places, making the distance between the hole in circle center hole and other each adjacent hole is 2 millimeters.The right-hand member of circle center hole locates to make a call to 13 diameters less than 1 millimeter hole to 29 millimeters to the right successively 5 millimeters of distance circle center holes, 7 millimeters, 9 millimeters, locates to make a call to an aperture at right-hand member apart from 32 millimeters of circle center holes.
With this piece plastic board coexist punch position have two wide 4 millimeters, length is pasted together greater than the plastic ruler of the empty frame of rectangle of 28 millimeters and 30 millimeters respectively and is combined into a flat circle scale.
Newly-designed compasses proposed by the invention also can directly be designed on the ruler, but those apertures that its needs to introduce the front are designed on two straight lines, make the distance between the Kong Yukong be increased to 4 millimeters.
If will increase the quantity of the circle that the present invention can draw, the quantity that only needs respectively increase a little unit lengths aperture corresponding with it at the circle center hole two ends can realize.
The compasses chi that adopts such scheme to make can be used as ruler and draws, again can with two pens incompatible picture circle that matches.It compares more conveniently, quick with original bipod compasses in use, and interface can not take place the circle that comes of drawing has deviation to connect phenomenon incessantly.Its cost is lower, and the technology during making, specification requirement are also lower, is easy to the large batch of manufacturing.
Description of drawings
The flat thin that Fig. 1 can draw the 4-60 millimeter for the present invention is moulded the structural representation of plate aperture Positioing compasses.
Fig. 2 is the structural representation of the combined ruler of the compasses of the present invention and Fig. 1 design.
Fig. 3 is the structural representation of the above-mentioned compasses chi that both are combined into.
Fig. 4 directly is designed on the ruler for the present invention, and aperture is distributed in the structural representation of two compasses chis on the straight line.
Fig. 5 can draw the structural representation of the compasses of 4-80 millimeter circle for the present invention.
Fig. 6 draws the enforcement schematic diagram that radius is 20 millimeters circles for the present invention.
Fig. 7 draws the enforcement schematic diagram that radius is 25 millimeters circles for the present invention.
The specific embodiment
As shown in Figure 6, left hand hold one-pen by center circle center hole 1 with ruler by living the center of circle on paper surely, the right hand hold one-pen be placed on the left side 20 millimeters places aperture in, the circle that a drive ruler of the right hand is fixed around the pen of left hand rotates a week, the circle that draws on paper simultaneously, the point of being fixed with the pen of left hand that promptly can draw is the center of circle.20 millimeters long are the circle of radius, draw other radius less than 30 millimeters fenestra with the fixing center of circle of center circle center hole, look for and draw circle with the hole of its radius corresponding length with said method and get final product.
If will draw radius greater than 30 millimeters circle, be that example illustrates with 52 millimeters, with the fixing center of circle, the hole 3 at 32 millimeters places of right-hand member, be the picture circular hole with the hole at 20 millimeters places of left end, the radius that can draw is 52 millimeters a circle; If its radius length is an odd number, be that example illustrates with 49 millimeters, with the hole 2 at 30 millimeters places of left end fixedly the center of circle be the picture circular hole with the hole at 19 millimeters places of right-hand member, the circle of 49 millimeters of the radiuses of can drawing.Use the present invention to draw that circle is main notices that circle center hole and the actual range of drawing circular hole are that the radius of a circle length of the picture of preparing gets final product.
The present invention can stamp graduation mark and make and look for the hole more convenient on plastic plate when actual fabrication, graduation mark is imprinted on the one side that plastic plate and ruler paste, and it is more longer to protect graduation mark not to be worn away service time in use.Also can compasses of the present invention be designed on set square or the protractor, make these two kinds of stationery also can be used for picture circle according to actual conditions.Use the method that the present invention introduced also to can be made into the compasses chi of chalk at the blackboard upper drawing circle.
Claims (5)
1, a kind of plane aperture Positioing compasses, it is characterized in that: mould in the flat thin of 30 millimeters of a block length 70 mm wides and get one 60 millimeters line segment on the plate, the line segment point midway is made a call to an aperture, this aperture is the center circle center hole, the circle center hole left end is made a call to an aperture every 2 millimeters and is made a call to 15 holes altogether, the circle center hole right-hand member locates to make a call to a hole at 5 millimeters, makes a call to an aperture at place, this hole every 2 millimeters and adds that this hole makes a call to 13 holes, and right-hand member is being made a call to a hole again at 32 millimeters places of distance.
