CN2136144Y - Multipurpose check-drawing ruler - Google Patents

Abstract

The utility model relates to a multipurpose check-drawing ruler. The integral structure of the utility model still fundamentally keeps the appearance of the existing ruler; both sides are marked with the scale of the linear measure; the multipurpose check-drawing ruler is a sliver-shaped ruler which is processed and molded with the organic glass material or the thermoplastic transparent material; a scribing slot [1] is designed in the middle of the multipurpose check-drawing ruler; compound line-transects [2] are designed above the scribing slot [1]. Various temporary tables desired by each one can be easily drew with the multipurpose check-drawing ruler which has the advantages of simple structure, low cost, convenient operation and good effect.

Description

Multipurpose check-drawing ruler

The utility model is to belong to a kind of many with drawing the lattice chi.

The existing common ruler of using is used for drawing interim form, and the system picture is transcribed exercise-book, and four limits measurement length on used quadrangle paper after the lattice fixed point, could be made the form of rule that draws earlier.Otherwise, operating personnel concentrate exactly, firmly making the form that comes that draws diligently also is that the lines imbalance is asymmetric, so it is also pretty troublesome, be not subjected to liking of people: though now have a kind of set square with cylindrical roller, its cost is higher, and it is also not parallel and asymmetric to draw lines with the scale system on the hand control cylinder.

The purpose of this utility model overcomes above-mentioned shortcoming exactly and provides a kind of simple in structure, and the many usefulness that can make the required separately various interim forms that draw are easily drawn the lattice chi.

Accompanying drawing has been described an embodiment of the present utility model.

Accompanying drawing: be with the shape and structure schematic diagram of drawing the lattice chi for many.

1---marking groove 2---compound line-transect 3---groove top

4---groove bottom 5---chi bottom 6---chi top margins

7---scale

Below in conjunction with accompanying drawing the utility model is described in detail.The many usefulness that proposed are drawn the lattice chi, its integral body has still kept the profile of existing common ruler substantially, both sides all indicate the scale of long measure, be to adopt pmma material to process or the thermoplastic transparent material, method one-shot forming with injection moulding is the whole ruler of a strip, middle design has a marking groove (1), for the two ends design of the intensity marking groove (1) of strengthening this chi is circular arc, and in the top of its marking groove (1) design has compound line-transect (2), the design of limit, below has the scale (7) of long measure.

Marking groove described in the utility model (1), its width is 06 centimetre, the distance of groove top (3) and compound line-transect (2) is 05 centimetre, and groove bottom (4) is 09 centimetre with the distance of chi bottom (5), is 1 centimetre in the distance of its compound line-transect (2) and chi top margin (6).

Its using method following (as accompanying drawing):

1, draws the parallel lines of 1Cm apart, to drop down onto marking groove (1) in the works, along groove bottom (4) article one straight line of drawing a picture, when drawing the second line again, to draw the lattice ruler moves down, make compound line-transect (2) and article one adjusting to a line of having drawn compound, just drawn at a distance of two parallel lines of 1Cm by the top Same Way second straight line of drawing a picture then, the full paper parallel lines of arbitrarily to draw of drawing analogous conclusions at a distance of 1Cm;

2, draw parallel lines at a distance of 2Cm, chi top margin (6) is aimed at compound with article one straight line that draws (referring to any line), along groove bottom (4) setting-out, the distance between the parallel lines that then draws is 2Cm with pen.

3, draw the parallel lines of 05Cm apart, with groove top (3) and article one straight line that draws, the distance between the parallel lines that then draws is 05Cm.

4, draw parallel lines at a distance of 15Cm, chi is turned around, it is compound that chi bottom (5) is aimed at article one straight line that draws (referring to any line), and along groove top (3) straight line of drawing a picture, the distance between the parallel lines that then draws is 15Cm with pen.

The utility model is compared with existing ruler, has following advantage:

1, can handle very skillfully, alleviate labor intensity of operating personnel greatly;

2, save the working time of measuring the lattice fixed point;

3, arbitrarily the draw form lines that come of system are parallel with lines, and each grid size unanimity also can be made the grid of the different size that draws, the form space of a whole page and used paper symmetry as required;

4, make this stroke lattice ruler, its marking groove can be saved material, and simple in structure, and cost is low easy to use, effective.

Claims (2)

1, a kind of many with drawing the lattice chi, it is characterized in that it is to be the whole ruler of a strip, middle design has a marking groove (1), the two ends design of marking groove (1) is circular arc, and having designed compound line-transect (2) again in the top of its marking groove (1), the design of limit, below has the scale (7) of long measure.

2, according to claim 1 stroke of lattice chi, the width that it is characterized in that marking groove (1) is 06 centimetre, groove top (3) is 05 centimetre with the distance of compound line-transect (2), the distance of groove bottom (4) and chi bottom (5) is 09 centimetre, is 1 centimetre in the distance of its compound line-transect (2) and chi top margin (6).
