Description

The utility model provides a drawing pen, in particular to a drawing pen which can make art designers or various poster designers use the pen to draw patterns, and can have more various changes, which uses a clutch rubber spring and an ink tube check Ink function, and when the pen is stopped, the nib and the ink tube can be separated quickly to avoid ink mixing, stably control the mixing ratio of multi-color ink on the nib, and can write long-distance clutch-style gradient Drawing pen structure.

The so-called gradient drawing pens on the market can be seen in Figure 1 (A) and (B), which contain two different colored ink tubes a, b and a drawing tip c with the top, where the ink tubes a and b are respectively Insert the left and right sides of the top of the same drawing pen, so that the two colors of ink flow from the left and right sides of the top of the pen to the bottom, and then mix through the two ends of the bottom edge to the middle; The primary color of the ink gradually produces a mixed color when it moves toward the middle; for example, if the left end of the two ink tubes is yellow and the right end is red, the nib starts to be yellow from the left end, and gradually moves to the middle part, then the red gradually becomes stronger and becomes a mixed orange. Further to the right, the yellow fades to red. However, the above-mentioned gradient drawing pen is a simple gradient pen, and its two ink tubes of different colors are fixedly inserted on the drawing pen tip. After the pen is not used for a period of time, the two-color ink will be completely mixed on the pen tip to form Single mixed color, and because the amount of ink penetration cannot be fully controlled, it will lead to disadvantages such as uneven mixing ratio, which prevents the practicability of the simple gradient pen from being fully utilized, and cannot be favored by consumers.

The utility model aims to provide a clutch-type gradient drawing pen which can overcome the above-mentioned shortcomings. The drawing pen tip utilizes the clutch rubber spring and the ink tube check function to allow the pen tip and the ink tube to be automatically separated when the drawing pen is stopped to avoid ink leakage. Continue to mix to achieve diversified use and practical purposes.

For this reason the utility model provides a kind of drawing pen, it is characterized in that it comprises:

A pen holder, which is provided with two ink tubes that can be filled with ink and a groove that can place the nib assembly;

An ink conduit having a round hole through which ink can seep into the tip of a drawing pen;

The water-stop rubber pad that controls the ink to continue to flow down or stop the flow, which is between the ink tube sleeve and the ink tube;

The ink tube sleeve is used for the insertion of the ink tube and fits on the clutch rubber spring;

Clutch rubber spring, which is placed between the drawing pen tip cover and the ink tube sleeve, can make it contract or relax when the drawing pen tip is pressed or released;

Drawing pen head cover, with hollow cylinder and screw hole on the top, covering body and protruding strips on the bottom, the screw hole cooperates with the stud of the ink conduit to locate the waterproof rubber pad, sleeve and clutch rubber spring, and the covering body The tip of the drawing pen can be placed and positioned by the protruding bar;

The drawing pen head is located in the covering body of the drawing pen head cover.

Taking a broad view of the above, it is known that the drawing pen structural design of the present utility model has the following advantages:

1. It can ensure the gradient effect: when the drawing pen head leaves the drawing surface, the drawing pen head is separated from the ink by the push force of the clutch rubber spring, that is, it is kept in a state of "water cut-off", so that it can block the ink from continuing to penetrate and promote the ink to continue No more mixing without limit, and the effect of color layering can't play its role.

2. Can control the color mixing ratio: because the ink tube is directly filled with ink instead of water-permeable material, when in use, the ink tube is directly inserted into the ink, and the ink flows down quickly, so that the two ends of the pen tip maintain their bright primary colors.

3Long-distance drawability: Since the ink is directly supplied to the tip of the drawing pen, it can be used directly, and the water output is large, so it can be used for long-distance drawing.

4. Simple structure and easy assembly: In addition to complete functions, its cost is even lower, which is completely in line with economic benefits.

5 When applied to a monochrome drawing pen, if you forget to put on the pen cap, the ink will not evaporate completely. If the ink on the tip of the drawing pen is dry, the ink can be quickly replenished, and it can be used immediately, which is economical and affordable.
