Abstract
The utility model relates to a ruler with a circle drawing function. The ruler comprises a ruler main body (1), wherein scale values (2) are arranged on the ruler surface of the ruler main body; the ruler is characterized in that a through groove (3), which is formed in a straight-line direction, is formed in the ruler surface of the ruler main body; a locating block (4) and a slide block (5) are arranged in the through groove; the locating block (4) is fixed at one end of the through groove (3); a locating needle (6) is arranged at the bottom of the locating block (4); the slide block (5) can slide along the through groove (3); and a pencil lead (7) is arranged at the bottom of the slide block (5). During drawing a straight line, the slide block first slides to a corresponding dimension position, then the locating block is pressed so that the locating needle is fixed together with a drawing board after penetrating through paper, and finally the straight line with a specified length can be drawn on the paper by using the pencil lead below the slide block as long as the slide block is pulled back; and during drawing a circle or an arc line, the slide block first slides to a corresponding dimension position, then the locating block is pressed so that the locating needle is fixed together with the drawing board after penetrating through paper, and finally the slide block is pressed and the pencil lead below the slide block can draw the circle or the arc line with a specified dimension on the paper by using the locating needle as circle center.
Description
Technical field
The utility model relates to a kind of drawing instrument, relates in particular to a kind of ruler with picture circle function.
Background technology
Ruler is a kind of drawing instrument of routine, on the upper surface near straight line one side, is provided with scale value, and this ruler can only be used for drawing and the measurement straight line.Compasses also are a kind of drawing instruments, are mainly used in picture circle and camber line.Ruler often separates use with compasses, and being inconvenient to work as very much need be by compasses when using compasses, and the compasses circle of size regulation that can not draw itself also need be through the measurement of rule.
Also do not have at present ruler with picture circle function.
Summary of the invention
The utility model technical problem to be solved is that a kind of ruler with picture circle function is provided to above-mentioned prior art present situation, and this ruler also need not in addition with just drawing specific length straight line and the circle of predetermined radius or camber line.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of ruler with picture circle function; Comprise the ruler body; The chi face of ruler body is provided with scale value, it is characterized in that: have the groove that runs through along the rectilinear direction setting on the chi face of said ruler body, this runs through and is provided with locating piece and slide block in the groove; Said locating piece is fixed on an end that runs through groove; The bottom of locating piece is provided with the pilot pin of exposing the ruler body downwards, and said slide block can be along running through the groove slippage, and the bottom of slide block is provided with the pencil-lead that exposes the ruler body downwards.
The upper surface of above-mentioned locating piece and slide block is provided with anti-skidding lines.Anti-skidding lines is set can be at sliding slider with push locating piece the time, and slide block and locating piece are difficult for leaving with the dislocation of finger joint, are convenient to operate.
The radius of the length that draws lines for ease of reading or drawn circle or circular arc, a side of above-mentioned slide block have the pointer portion that points to scale value.
Compared with prior art, the advantage of the utility model is: this ruler need not in addition with just drawing specific length straight line and the circle of predetermined radius or camber line; When drawing straight line, earlier slide block is slid onto the corresponding size position, push locating piece then; Make pilot pin see through paper and drawing board is fixed, the last slide block of only need pulling back, the pencil-lead of the slide block below straight line of specific length that just on paper, draws; When drawing circle or camber line; Also be earlier slide block to be slid onto the corresponding size position, push locating piece then, make pilot pin see through paper and drawing board is fixed; Pinning slide block at last is the center of circle with the pilot pin, the pencil-lead of slide block below just can on paper, the draw circle or the camber line of given size.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1～6, be a preferred embodiment of the utility model.
A kind of ruler with picture circle function comprises ruler body 1, and the chi face of ruler body 1 is provided with scale value 2; Have on the chi face of ruler body 1 and run through groove 3 along the rectilinear direction setting; This runs through, and constraint has locating piece 4 and slide block 5 in the groove 3, and locating piece 4 is fixed on an end that runs through groove 3, and the bottom of locating piece 4 is provided with the pilot pin 6 of exposing ruler body 1 downwards; Slide block 5 can be along running through groove 3 slippages, and the bottom of slide block 5 is provided with the pencil-lead 7 that exposes ruler body 1 downwards.The upper surface of locating piece 4 and slide block 5 is provided with anti-skidding lines 8.One side of slide block 5 has the pointer portion 9 that points to scale value 2.
When drawing straight line; Earlier slide block 5 is slid onto the corresponding size position; At this moment the 9 indication scales of the pointer portion on the slide block 5 are exactly the length that will draw straight line, push locating piece 4 then, and the pilot pin 6 on the locating piece 4 is fixed through paper and drawing board; The last slide block 5 of only need pulling back, the pencil-lead 7 of the slide block 5 belows straight line of specific length that just on paper, draws.
When drawing circle or camber line; Also be earlier slide block 5 to be slid onto the corresponding size position; At this moment the 9 indication scales of the pointer portion on the slide block 5 are exactly the size that will draw circle or arc radius, push locating piece 4 then, and the pilot pin 6 on the locating piece 4 is fixed through paper and drawing board; Pinning slide block 5 at last is the center of circle with pilot pin 6, the pencil-lead 7 of slide block 5 belows just can on paper, the draw circle or the camber line of given size.
