Abstract

The utility model relates to a standard line ruler used for drawing engineering drawings, and is exclusively used for drawing straight lines, broken lines, dot lines, double dot lines. The standard line ruler is formed by a ruler body which is made of organic glasses and is adhered to a film. A ruler face is provided with a graduated ruler, a broken-line ruler, a dot-line ruler and a double-dot-line ruler. A user can draw standard dot lines easily like drawing straight lines. The utility model can be widely used for drawing engineering drawings.

Description

Standard line ruler

The utility model relates to drawing instrument, a kind of standard figure line chi of drawing line usefulness in the Graphing of Engineering process of saying so in more detail.

People draw in the Graphing of Engineering process in the past, often will draw dotted line, chain-dotted line and double dot dash line, all are to draw by ruler by hand, owing to there is not special-purpose drawing tool, the dotted line that draws, chain-dotted line are even inadequately, and draw slowly, also relatively require great effort.

The purpose of this utility model is in order to overcome the defective of known technology, to provide a kind of and both can draw straight line, can draw the standard figure line chi of dotted line, chain-dotted line and double dot dash line again, draws soon and easily, the Points And lines section of drawing all is a standard.

The utility model is to realize like this, on this standard figure line chi face, be carved with the scale on ruler, can be used for measuring the length of straight line, side at scale, have Dotting ruler and/or chain-dotted line chi and/or double dot dash line chi or chi is used in other drawing, some chis are combined on the chi face, for the illustrator brings great convenience.Standard figure line chi is to be bonded by plastics blade and matrix.

The plastics blade is made for best with lucite or transparent plastic, also available other plastics or non-plastic material are made.Matrix uses photographic film sheet base for well, and this material had been not only transparent, but also solid, also can use other sheeting and plastics blade to be bonded.

Before plastics blade and matrix are bonding, should leave the strip hole of at least three wide 1～4 millimeter (2～3 millimeters are) at plastic ruler on one's body, its length is decided with chi is long, and is V-shaped for well in a rectangular side.The reverse side of V-type face is stained with matrix, and punching out goes out the square hole and/or the oblong aperture of different size equal intervals then.On matrix, go out equidistantly identical square hole, then make Dotting ruler; Go out two oblong aperture, the centre is a short square hole, and its spacing equates, then makes the chain-dotted line chi; Go out two oblong aperture, the centre is two short square holes, and its spacing equates, then makes the double dot dash line chi.Hole on all chis and pitch of holes are advisable with interior at one millimeter.(can require to decide) according to the standard figure line.

The utility model has many advantages than traditional manual setting-out, mainly be that the dotted line that draws or chain-dotted line or double dot dash line are evenly attractive in appearance, and draw soon, laborsaving, as long as just can be drawn as desirable chain-dotted line as the picture straight line, the line of drawing is long more, many more, then its advantage is just outstanding more, and this chi is sturdy and durable, is applicable to very much the Graphing of Engineering drawing.

Below in conjunction with accompanying drawing the utility model is described further.

Accompanying drawing Fig. 1 is the utility model front view;

Fig. 2 is the A-A profile of Fig. 1.

Accompanying drawing 1,2 is an embodiment.

Standard figure line chi is to be bonded by plastics blade (6) and matrix (5).One side in plastics blade (6) is carved with rule (1), in a side of rule (1), has Dotting ruler (2), chain-dotted line chi (3), double dot dash line chi (4).

Plastics blade (6) is to make with lucite, and matrix (5) is to adopt photographic film sheet base.Before plastics blade (6) and matrix (5) are bonding, on the chi face of plastics blade (6), mill three wide slotted holes of 2 millimeters, the last end mill in hole becomes V-type, and three slotted holes are evenly distributed on the chi face, bonding then matrix (5).Go out spacing in plastic ruler height hole, matrix (5) upper edge and be 1 millimeter some identical square hole, square hole is 2 * 2 millimeters, make Dotting ruler (2), as long as the one side of matrix (5) will be arranged, be placed on the paper, use pen along last groove, as the picture straight line, then one long 2 millimeters, the about 1 millimeter dotted line of spacing draws.On matrix (5), go out a long oblong aperture of 10 millimeters along another slotted hole of plastics blade (6), at a distance of 1 millimeter, go out one 2 millimeters square hole again, one is long and the other is short continuously, then makes chain-dotted line chi (3).On matrix (5), along (6) slotted holes of plastics blade, go out two long oblong aperture of 10 millimeters, the middle square hole that dashes two 2 millimeters, apart from being 1 millimeter, continuous one long two short punching out becomes double dot dash line chi (4) between the hole.

The utility model has many advantages than traditional manual setting-out, mainly be that the dotted line that draws or chain-dotted line or double dot dash line are evenly attractive in appearance, and draw soon, laborsaving, as long as just can be drawn as desirable chain-dotted line as the picture straight line, the line of picture is more long, more many, and then its advantage is just more outstanding, and this chi is sturdy and durable, is applicable to very much the Graphing of Engineering drawing.
