Abstract
The utility model belongs to small drawing tools and products. The utility model has the function of simply and accurately drawing parallel lines due to a structure with the function, the design details of the structure is special as the followings introduced by the utility model, and the structure is no available for traditional rulers. The utility model comprises two rulers: a basic ruler A and a slide ruler B. A trapezoidal boss 1 is formed on one side of the basic ruler, a trapezoidal groove 2 is formed at one end of the slide ruler B, the trapezoidal boss 1 and the trapezoidal groove 2 are relatively smooth and can be well embedded together; thus, once the basic ruler A is well fixed, the slide ruler B can stably slid parallel to the basic ruler A without the displacement. Two small oval grooves 5 which do not penetrate a ruler board are formed in the middle of the basic ruler A, so that fingers can better fix the basic ruler A. A plurality of cross holes 3 are formed on a central line 7 of the slide ruler, semi-convex lenses are arranged in the holes, when two cross holes 3 are used for carrying out the two-point alignment, the semi-convex lenses can play the role of appropriate amplification, thereby facilitating the alignment of the central line 7 of the slide ruler B and a straight line to be parallel to. A plurality of obvious lines 4 are marked at the groove end of the slide ruler B, and the translation distance of the slide ruler B can be known by simultaneously combining scale marks 6 of the basic ruler A. Therefore, people can use the groove slide type parallel ruler which can simply and accurately draw the parallel lines.
Description
Affiliated technical field
The utility model relates to a kind of ruler that can conveniently draw parallel lines, and especially can accurately locate and draw the parallel rule to the set a distance parallel lines.
Background technology
At present, ruler on the market is of all kinds, and different combinations is arranged, but is not used for drawing the ruler of parallel lines specially.People, especially be engaged in the people of Graphing of Engineering for those, drawing parallel lines is the things that often run into, the method of drawing parallel lines is exactly with one a long limit of the ruler straight line parallel with desire to be overlapped, with another ruler vertical direction near on one one side of chi, slide last one then carefully to certain a bit, mark parallel lines at last ruler.This method is very simple, and the people who still much streaks parallel lines knows, if a little accidentally, marking the possibility of coming be not parallel lines just, its reason just is that these two rulers well are not engaged togather, and causes in the process of translation, is easy to cause loosening and is offset.
Summary of the invention
Can not stablize the deficiency that accurately draws parallel lines in order to overcome existing ruler, the utility model provides a kind of parallel rule, this parallel rule parallel lines that not only can stably draw, and can come setting-out by given parallel distance.
The technical scheme that the utility model technical solution problem is adopted is: the utility model is made up of two rulers: basic chi and slide rule.Make trapezoid boss (1) in a side of basic chi, one end of slide rule is made trapezoidal groove (2), and trapezoid boss (1) and trapezoidal groove (2) be smoother all, both can be good at being entrenched togather, like this, as long as fix basic chi, slide rule just very stably parallel sliding and do not occur the skew.Driven two little oval grooves (5) of not wearing the chi plate thoroughly at the middle part of basic chi, so just can make the better fixed base chi of finger.In the Central Line (7) of slide rule, be provided with several crosshair holes (3), it in these holes semi-convex mirror body, when when wherein 2 alignments are carried out in two crosshair holes (3), semi-convex mirror body can play suitable amplification, can be more convenient for making the Central Line (7) of slide rule to align with initial parallel lines.Groove ends at slide rule B is carved with some comparatively significantly grooves (4), can just can know the distance of slide rule translation in conjunction with the graduation mark (6) of basic chi.
The beneficial effects of the utility model are, can stablize the parallel lines that draw, and draw parallel lines by given parallel distance, and are simple in structure, flexible operation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Figure one is a basic chi structure chart of the present utility model.
Figure two is slide rule structure charts of the present utility model.
1. trapezoid boss among the figure, 2. trapezoidal groove, 3. crosshair hole and enlarged drawing thereof, 4. groove 5. little oval grooves, 6. basic chi graduation mark, 7. slide rule Central Line.
The specific embodiment
During use, earlier trapezoid boss of basic chi (1) and slide rule trapezoidal groove (2) are lumped together, select two crosshair holes (3) to align with initial parallel lines then, fix basic chi again, the slip slide rule just can mark parallel lines.In conjunction with scale (4) and graduation mark (6), just can accurately locate and draw parallel lines by given parallel distance.
Claims (3)
1. a parallel rule is combined by basic chi and two rulers of slide rule, and it is characterized in that: basic chi is provided with trapezoid boss, has trapezoidal groove on the slide rule, and the two is entrenched togather, and required parallel lines can stably draw.
2. parallel rule according to claim 1 is characterized in that: basic chi trapezoid boss and slide rule trapezoidal groove all are smooth, can well be entrenched togather, and can easily slide; Graduation mark is carved with on trapezoid boss limit at basic chi, is provided with groove at groove one end of slide rule, and the two is used for locating and the displacement of definite slide rule; Be provided with the crosshair hole of Central Line and several semi-convex mirror body shapes in slide rule central authorities, parallel initial line is used for aliging.
3. parallel rule according to claim 1 is characterized in that: driven two little oval grooves of not wearing the chi plate thoroughly at the middle part of basic chi, so just can make the better fixed base chi of finger.
