Abstract

The utility model relates to a drawing pen with multiple heads, which is suitable for drawing line figures with different thickness, belonging to a drawing apparatus. The utility model is characterized in that the basic structure of the intrinsic drawing pen is kept; two to three pen points with different standards are synchronously installed on a pen head only; each pen point is formed by that a pen pin is inserted into a pen rod pipe; the pen point and a body axis present an angle which slants outwards; the pen point part which extends to the front capsula of the pen along with the pen head, is spaced out by a clapboard type hollow body which is arranged on the front of a pen core; lines with different thickness can be drawn by only turning the pen body when using the drawing pen with multiple heads. The utility model solves the problem of continually replacing pens when drawing lines with different thicknesses with the traditional drawing pen with single head, with the advantages of high work efficiency, simple structure, and low cost.

Description

The bull drawing pen

The utility model bull drawing pen is applicable to and draws the different thicknesses bargraphs, belongs to drawing appliance.

Present commercially available drawing pen mostly is nib of one-pen, when drawing the figure of different thicknesses lines, needs constantly to change drawing pen, and promptly inconvenience is time-consuming again.

The purpose of this utility model is to overcome the shortcoming that above-mentioned drawing pen exists, and design a kind ofly not change the drawing pen essential structure, and set up the different size nib on one-pen, does not change the figure that drawing pen just can be drawn out the different thicknesses lines with realization.

The purpose of this utility model can realize in the following manner.

Keep the basic structure of common drawing pen constant, capsule 2, nib 3, pen core 6, the more common drawing pen overstriking of the cap for brush before penholder, a capsule 1, the pen, pen core front end 7 is positioned at a preceding capsule 2 for iris type hollow body, 2-3 needle tubings 4 are with being contained on the nib 3, needle tubing 4 is outward-dipping angle with a body axis direction, insert a corresponding needle tubing 4 after capsule inner route clapboard formula pen core front end 7 separates before pen with the pin 5 of a needle tubing 4 equal numbers respectively, constitute the bull nib thus.

Inclination angle between needle tubing 4 and the body axis is 10 °-15 °; When the bull nib was 2, it was symmetric configuration on nib 3, and pen core front end 7 is an iris type sheet hollow body (see figure 7); When the bull nib was 3, it was evenly distributed on nib 3, and pen core front end 7 is a garden cylindricality hollow body; (see figure 8); The thickness of each nib can be respectively 0.3 millimeter, 0.6 millimeter, 0.9 millimeter specification commonly used.

This bull drawing pen is compared following advantage with common single head drawing pen: because of the nib with 0.3 millimeter, 0.6 millimeter, 0.9 millimeter different size is loaded on the nib together, when drawing the figure of different thicknesses lines, frequently change-fountain pen, need only just can finish by rotating penholder, thereby easy to use, improve work efficiency; Before pen, be provided with the pen core front end of iris type hollow body in the capsule, can guarantee that ink is unimpeded, also prevent the mutual interference of several pin phases; The basic structure that does not change former drawing pen only increases nib, makes it simple in structure, and is cheap.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1,2,3 is respectively the utility model capsule, the preceding capsule of pen, nib and nib each several part cutaway view;

Fig. 4, Fig. 5 be respectively have 2,3 written A view;

Fig. 6 is a pen core structure cutaway view;

Fig. 7, Fig. 8 are respectively the pen core front end B view with 2,3 pens.

A 1-capsule among the figure, capsule before 2-pen, 3-nib, a 4-needle tubing, a 5-pin, 6-pen core, 7-pen core front end, 8-iris type sheet hollow body pen core front end, 9-garden cylindricality hollow body pen core front end, 10,11-2 nibs, 12,13,14-3 nibs.

With 3 drawing pens is example, with penholder, capsule 1, capsule 2 before the pen, nib 3, pen core 6, press the original structure assembling after the cap for brush overstriking, a capsule 1 is inserted in the rear end of pen core 6, its pen core front end 7 is a garden post hollow body shape (shown in 9 among Fig. 8), this garden post hollow body pen core front end 9 stretches into a front portion of preceding capsule 2, and in the middle of being positioned at, the front portion of the preceding capsule 2 of pen is inserted at the rear portion of nib 3, with 0.3 millimeter, 0.6 millimeter, 0.9 respectively being separated by 120 °, a needle tubing of 3 kinds of different sizes of millimeter is contained in (see figure 5) on the nib 3,3 needle tubings have 10 °-15 ° the oblique angle that leans outward respectively with a body axis, again 3 pins are inserted corresponding needle tubing respectively and constitute 3

nibs

12,13,14, (see figure 3) in the nib 3 is stretched at the rear portion of pin, and 3 stretch into a front portion of preceding capsule 2 with nib, by garden post hollow body shape pen core front end 93 pin rear portions are separated.Only need the pen with rotary body just can draw the lines of different thicknesses during use.

Claims

1, a kind of bull drawing pen comprises penholder, capsule, capsule before the pen, pen core, nib, the cap for brush and the nib of forming by a needle tubing and a pin, it is characterized in that: penholder, capsule (1), capsule (2) before the pen, nib (3), pen core (6), the more common drawing pen overstriking of the cap for brush, pen core front end (7) is positioned at a preceding capsule (2) for iris type hollow body, 2-3 needle tubings (4) are with being contained on the nib (3), needle tubing (4) is the angle that leans outward with a body axis direction, insert a corresponding needle tubing (4) after capsule (2) inner route clapboard formula pen core front end (7) separates before pen with the bobbin (5) of a needle tubing (4) equal number respectively, constitute the bull nib thus.

2, bull drawing pen according to claim 1 is characterized in that: the inclination angle between a needle tubing (4) and the body axis is 10 °-15 °; When the bull nib was 2, it was symmetric configuration on nib (3), and pen core front end (7) is an iris type sheet hollow body; When the bull nib was 3, it was evenly distributed on nib (3), and pen core front end (7) is a garden cylindricality hollow body; The thickness of each nib can be respectively 0.3 millimeter, 0.6 millimeter, 0.9 millimeter specification commonly used.
