[0002] Double-line pen is a special writing tool, which usually has two writing liquid pen heads and can write two lines at the same time or alternately. The design of double-line pen allows users to complete two parallel lines or lines of different colors and thicknesses at the same time when writing, and is widely used in fields such as drawing, artistic creation, marking, calligraphy and decoration. Especially in the field of drawing design and engineering drawing, artists and designers often use double-line pen to draw two parallel lines at the same time when making sketches, outlines and decorative patterns, which increases the depth and three-dimensionality of the work. In engineering drawing, double-line pen can be used to represent different levels or different types of lines (such as building structure lines and annotation lines), making the drawing clearer and easier to read.

[0003] The main feature of double-line pen is its double-head design. The two pen heads are supplied with ink through a shared ink storage system or independent ink pipes, which can usually provide different writing effects. Common double-line pens include double-color double-head pens (i.e. two pen heads provide different colored ink), double-thickness pens (two pen heads have different line thickness effects), and some high-end artistic tools that can simultaneously write thin and thick lines as needed.

DETAILED DESCRIPTION

[0023] In order to more understand the technical content of the utility model, specific embodiments are raised and the following is described with the attached drawings.The aspects of the utility model are described in the disclosure with reference to the drawings, and many illustrated embodiments are shown in the drawings.The embodiments of the disclosure are not necessarily defined in all aspects including the utility model.It should be understood that the various concepts and embodiments introduced above, and those concepts and embodiments described in more detail below can be implemented in any one of many ways, because the concepts and embodiments disclosed by the utility model are not limited to any implementation manner.In addition, some aspects of the utility model can be used alone, or used in any appropriate combination with other aspects of the utility model.

[0024] Embodiment 1

[0025] As Figures 1-4 shown, a double-line pen pen head, including pen seat 1, one side of pen seat 1 is fixedly connected with first connecting square tube 2 and second connecting square tube 3, first connecting square tube 2 and second connecting square tube 3 are in echelon, the other side of pen seat 1 is fixedly connected with first liquid guide tube 4 and second liquid guide tube 5, the interval of first liquid guide tube 4 and second liquid guide tube 5 is 0.5cm, pen seat 1, first connecting square tube 2, second connecting square tube 3, first liquid guide tube 4 and second liquid guide tube 5 are communicated, and the liquid of double-line pen can pass through first connecting square tube 2 and second connecting square tube 3 in turn and enter first liquid guide tube 4 and second liquid guide tube 5 respectively, and the end of first liquid guide tube 4 and second liquid guide tube 5 is provided with liquid outlet head 7.

[0026] The second connecting tube 3 can be inserted into the end of the pen tube 9, and the end of the second connecting tube 3 inserted into the pen tube 9 is provided with a sealing rubber ring 8. The pen tube 9 is provided with ink, and the sealing rubber ring 8 is arranged at the connection between the second connecting tube 3 and the pen tube 9, which can effectively prevent ink leakage. These sealing rubber rings ensure that ink only flows out through the liquid outlet head 7 during writing, and will not leak due to loosening of the connection part, ensuring the cleanliness and comfort of the user during writing.

[0027] The core working principle of the double-line pen tip is to transmit ink from the pen tube to the liquid outlet head through the double liquid guide tubes. Specifically, the ink first flows into the first connecting tube 2 and the second connecting tube 3 in sequence through the pen tube. These two connecting tubes are designed in a stepped manner, which can accurately control the flow of ink and ensure that the ink is evenly distributed to the two liquid guide tubes through the pen seat 1 pipeline. The ink flows through the first liquid guide tube 4 and the second liquid guide tube 5 in sequence, and is finally released through the liquid outlet head 7, completing the writing of two lines.

[0028] During the flow of ink, the first liquid guide tube 4 and the second liquid guide tube 5 respectively transport different ink to the liquid outlet head, forming two parallel writing lines. By designing different liquid guide tube spacings, such as 0.24 cm, 0.5 cm or 0.7 cm, users can choose the writing effect that suits their needs. In this way, the double-line pen can draw two clear and uniform lines at the same time, meeting the needs of drawing, calligraphy or decorative creation.

[0029] Embodiment 2

[0030] As shown in Figures 1-4 In this embodiment, the first liquid guide tube 4 and the second liquid guide tube 5 are fixedly connected by a reinforcing rib 6. The reinforcing rib 6 fixes the first liquid guide tube 4 and the second liquid guide tube 5 together, enhancing the stability between the liquid guide tubes and preventing the pipeline from deforming or breaking due to excessive pressure or external force. The reinforcing rib functions to fix the liquid guide tubes together, maintaining the overall stability of the pen tip and ensuring that the flow of ink is not affected by external factors.

[0031] In this embodiment, the spacing between the first liquid guide tube 4 and the second liquid guide tube 5 is 0.7 cm, and the cross-sectional area of the pen seat 1 is larger than that of the first connecting tube 2, which can ensure complete liquid outlet.

[0032] In this embodiment, the pen seat 1, the first connecting tube 2, the second connecting tube 3, the first liquid guide tube 4 and the second liquid guide tube 5 are all made of plastic, which ensures the lightness and durability of the pen tip. During long-term use, the design and material of the pen tip ensure the stability of the ink flow, avoiding the problem of uneven ink flow or pen tip damage due to long-term use.

[0033] In this embodiment, the first connecting pipe 2 and the second connecting pipe 3 are both flat, and the cross section of the first connecting pipe 2 and the second connecting pipe 3 is square. The flat design facilitates handheld replacement. The design of the double-line pen tip allows the second connecting pipe 3 to be inserted into the pen tube 9, providing strong compatibility and adapting to different models of pen tubes. Users only need to replace the pen tip to adapt to different pen tubes, further improving the applicability and flexibility of the product.

[0034] The double-line pen tip of the present application is designed to be detachable, and the second connecting pipe 3 can be inserted into the end of the pen tube 9. Users can easily replace pen tips of different distances according to their needs. When adjusting the line spacing, users only need to replace the pen tip, without the need to purchase multiple pen tubes. This design provides higher flexibility and economy.

[0035] The double-line pen tip of the above embodiment realizes more convenient use and maintenance through innovative structural design and material selection, allowing users to flexibly adjust the double-line spacing while ensuring the stability and cleanliness of writing, providing more efficient and economical writing tools for various users.

[0036] Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application. Those skilled in the art can make various modifications and improvements without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application shall be subject to the definition of the claims.
