Abstract
The utility model belongs to the pencil class of a stationery article, particularly a special pencil for drawing, comprising a special drawing lead core, a special drawing pencil and a special drawing moving pencil. The cross-sectional shape of the lead core of the pencil is flat, and the thickness of the lead core is the thickness of a line. The utility model has the advantages of high utilization rate, convenient drawing and even thickness of the drawing line. The drawing people can draw standard drawings with high quality by using the special pencil for drawing.
Description
The utility model belongs to the pencil class in the stationery, is a kind of special-purpose drawing pen, comprises the plumbous heart of special-purpose drawing, special-purpose drawing pencil and special-purpose drawing propelling pencil.
Stipulated to draw pattern in the national standard mechanical drawing and should adopt the figure line of regulation, and stipulated the basic width of various line styles and the ratio between the width, in same pattern, the width of identical line style should be consistent.But the plumbous heart of present drawing pencil and propelling pencil all is circular, have following shortcoming with these two kinds of pen mappings: the line weight that draws is difficult to evenly, the width of identical line style is difficult to consistent, and the ratio of synteny width is not difficult to conform to the ratio of drafting standard regulation yet; Need frequently cut the plumbous heart, plumbous heart waste is serious; Because be subjected to the restriction of plumbous heart intensity, the specification of movable plumbous heart minimum is φ 0.5mm, produce more that the plumbous heart of small dimension is impossible, can not satisfy the requirement of drawing line minimum widith far away.
The purpose of this utility model provides a kind of special-purpose drawing pen, comprises the plumbous heart of special-purpose drawing, special-purpose drawing pencil, special-purpose drawing propelling pencil.The line style that this pen can draw various different in width, easy to use, the line weight that draws evenly, steadily to overcome the defective that the plumbous heart pen drawing of present circle exists, helps the drawing personnel to improve draught smanship.
The utility model is achieved in that
A kind of special-purpose drawing pen comprises the plumbous heart of special-purpose drawing, special-purpose drawing pencil, special-purpose drawing propelling pencil.The transverse shape that it is characterized in that the plumbous heart of pen is flat, the thickness of the plumbous heart is to the basic demand of various width of the graphic line and definite according to " mechanical drawing " standard, the pen of each specification is exclusively used in the figure line of a kind of width of picture, just can the draw figure line of 3～9 kinds of different in width of the pen of making 3～9 kinds of different specification sizes, the drawing personnel select the wherein pen of several specifications for use according to the needs of drawing, and make the plumbous heart thickness of selecting for use identical with the ratio of the line style width of drafting standard regulation, meet " mechanical drawing " specified standard drawing with regard to drawing.The utility model will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the plumbous core structure schematic diagram of the special-purpose drawing of flat, rectangular;
Fig. 2 is special-purpose drawing pencil structural representation.
Fig. 3 is special-purpose drawing propelling pencil structural representation.
Among the figure: the plumbous heart of the special-purpose drawing of 1-flat, rectangular; 2-presss from both sides the timber of the plumbous heart; The plumbous heart of the special-purpose drawing of 3-; 4-ammonium button; The 5-hook; The 6-overcoat; The plumbous heart storage facility of 7-; The plumbous heart of the special-purpose drawing of 8-; The 9-spring; The 10-branch sleeve; The flat movable sleeve of 11-; The flat spring clip of 12-; The 13-pencil stub; The flat nib of 14-.
The cross section of the special-purpose plumbous heart of drawing (1) is that flat, rectangular or minor face are that circular arc, long limit are rectilinear flat form.Its specification can be chosen in long limit 1～4mm, thickness 0.2～1.2mm by drafting standard.Shown in figure (2), with special use chart the plumbous heart (3) be installed in the plumbous heart of folder timber (2) just the centre made special-purpose drawing pencil, during use, the timber (2) that presss from both sides the plumbous heart is reamed, the non-sharpenning plumbous heart just can directly be drawn.Shown in figure (3), the nib (14) and the spring clip (12) of special-purpose drawing propelling pencil, movable sleeve (11) is and the special use supporting flat pattern of the plumbous heart (8) that charts, the special-purpose plumbous heart of drawing (8) is stored in the storage facility (7), storage facility is made flat pattern, more in plumbous heart guiding, nib (13) is the location tight fit with branch sleeve (10), so that collet (12) and nib (14) contraposition, be convenient to the plumbous heart (8) and stretch out nib (14) smoothly, press knob (4), promote descending the relaxing of collet (12), the flat plumbous heart (8) stretches out nib (14) under the gravity effect, the back promotion spring clip (12) under the effect of spring (9) of loosing one's grip is up, under the effect of movable sleeve (11), lead diameter clip is lived.
The utility model compared with prior art has following advantage; Do not cut the plumbous heart, improved the utilization rate of the plumbous heart; Because the area of section of the plumbous heart increases, thereby to make the plumbous heart and the softer plumbous heart of hardness that thickness is 0.2～0.3mm be feasible, overcome the shortcoming that propelling pencil can not be drawn hachure; Because the plumbous heart is flat, with the face width that contacts of drafting instrument, thereby much more steady than the circular plumbous heart during setting-out; The line weight that draws is even, and the width of identical line style is identical, and the ratio of synteny width does not meet the ratio that drafting standard requires, thereby has greatly improved the quality of drawing drawing, makes drawing more attractive in appearance, has significant economic benefit and social benefit.
