Abstract
Description
Technical Field
[0001] This application relates to the field of stationery, and in particular to a marker nib. Background Technology
[0002] Markers are widely used in daily life, especially in the fields of writing and drawing.
[0003] In the process of creating a painting, it is often necessary to use some auxiliary tools to draw standard straight lines. During this process, the side of the marker tip will come into contact with the auxiliary tool, causing ink to stain the tool. Since multiple colors are often used in the painting process, different colored markers can easily cause color bleeding when used with the same auxiliary tool, thus affecting the painting effect. Utility Model Content
[0004] To prevent ink from staining auxiliary tools during use, this application provides a marker tip.
[0005] The marker tip provided in this application adopts the following technical solution:
[0006] A marker tip includes a writing tip, a fixing part for abutting against the pen shell, and an ink guiding part for conveying ink. The writing tip and the ink guiding part are respectively disposed at both ends of the fixing part. The writing tip includes a transition part fixedly connected to the fixing part and a writing part disposed on the side of the transition part away from the fixing part. An anti-scratch shell is circumferentially connected to the outer surface of the transition part, and the anti-scratch shell extends toward and fits the writing part.
[0007] By adopting the above technical solution, when the marker is brought close to an auxiliary tool such as a ruler during use, the anti-scratch shell will come into contact with the ruler, thereby preventing the pen tip from carrying ink out and staining the ruler; at the same time, the anti-scratch shell can prevent the side wall of the pen tip from being scratched by the ruler, thus playing a role in protecting the pen tip.
[0008] Optionally, one side of the writing part is inclined toward the pen tip axis to form an anti-scratching surface, and the anti-scratching surface forms an angle of 6°-8° with the pen tip axis.
[0009] By adopting the above technical solution, when using markers with tools such as rulers, the concave anti-scratch surface ensures that there is always a certain gap between the pen tip and the ruler, effectively preventing the pen tip from scratching the ruler. This prevents the marker ink from staining the auxiliary tools, reduces the number of times writing needs to be interrupted due to ink stains, and allows users to focus more on writing.
[0010] Optionally, the writing part on the side opposite to the anti-scratch surface is completely covered by the anti-scratch shell.
[0011] By adopting the above technical solution, the anti-scratch shell can play a certain supporting role. When writing, the anti-scratch shell can effectively support the pen tip and prevent it from bending, thereby ensuring the stability of writing.
[0012] Optionally, the writing section is inclined towards the side closer to the transition section to form a writing surface, and the inclination angle of the writing surface is 18°-22°.
[0013] By employing the above technical solution, the pen can produce a rich variety of brushstroke effects when writing or drawing. By adjusting the angle between the pen and the paper, the contact area between the writing surface and the paper is changed, thus allowing the writing surface to draw lines of varying thicknesses. When the pen and paper are at a certain angle, the contact area is small, resulting in thinner lines; as the angle changes, the lines drawn also change, ensuring flexibility in use.
[0014] Optionally, the writing surface is set to rounded corners.
[0015] By adopting the above technical solution, when using a marker, setting the writing surface to rounded corners can effectively reduce friction between the writing part and the paper, thereby reducing wear on the writing part during the writing process and effectively improving its service life.
[0016] Optionally, the writing part has inclined surfaces on both sides and is mirror-symmetrical about the axis, with the included angle between the two inclined surfaces being 30°-40°.
[0017] By adopting the above technical solution, when the writing surface is in full contact with the paper, the beveled surfaces on both sides of the writing part allow the user to swing around the contact surface, thus facilitating the user's lateral movement of the marker and improving ease of use. At the same time, the beveled design prevents accidental contact between the pen tip and auxiliary tools such as rulers, effectively preventing ink smudges and maintaining a clean writing environment.
[0018] Optionally, the radius of the transition portion is larger than the radius of the fixed portion.
[0019] By adopting the above technical solution, the bottom wall of the transition section can abut against the end of the pen shell when the pen tip is installed, thereby ensuring that the marker tip is stably fixed to one end of the pen shell. This prevents the marker tip from retracting during writing and ensures stability during writing.
[0020] Optionally, the ink guide part is a frustum, and the radius of the ink guide part gradually decreases towards the side away from the fixed part.
[0021] By adopting the above technical solution, the radius of the end of the ink guide part away from the fixed part is smaller, which can ensure that the ink can be smoothly transferred from the ink guide part to the pen tip, thus ensuring the continuity and stability of the ink during writing.
[0022] In summary, this application has the following beneficial effects:
[0023] 1. By incorporating an anti-scratch shell, when using markers with auxiliary tools such as rulers, the anti-scratch shell effectively prevents the pen tip from carrying ink out and staining the ruler. At the same time, the anti-scratch shell effectively protects the pen tip from being scratched by hard tools such as rulers, thus preventing pen tip wear and ensuring good writing performance and extending the lifespan of the pen.
[0024] 2. By tilting the writing surface towards the transition section, the marker can produce a variety of stroke effects when used. By changing the angle between the pen and the paper, the contact area between the writing surface and the paper is changed, allowing the writing surface to draw lines of different thicknesses, thus improving the flexibility of use.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses a marker tip. (See also...) Figure 1 The marker pen tip includes a pen tip 1 for writing, a fixing part 2 for contacting the pen casing, and an ink guide part 3 for conveying ink. The pen tip 1 and the ink guide part 3 are respectively located at both ends of the fixing part 2. When using the marker pen, the end of the ink guide part 3 away from the fixing part 2 will contact the ink reservoir containing ink, and the ink will be conveyed to the pen tip 1 through capillary action. At this time, when the pen tip 1 contacts the paper, the ink will be drawn out, thereby realizing the writing function of the marker pen.
[0031] Reference Figure 1 , Figure 2The pen tip 1 includes a transition portion 11 fixedly connected to the fixing portion 2 and a writing portion 12 disposed on the side of the transition portion 11 away from the fixing portion 2. A scratch-resistant shell 13 is circumferentially connected to the outer surface of the transition portion 11, and the scratch-resistant shell 13 extends towards the writing portion 12. When using a marker, if it is necessary to draw a straight line, it is often necessary to place the side wall of the marker tip 1 against an auxiliary tool such as a ruler. At this time, the scratch-resistant shell 13 can come into contact with the ruler, preventing the side wall of the pen tip 1 from directly contacting the ruler, thereby effectively preventing the side wall of the pen tip 1 from carrying ink out and staining the ruler, ensuring the cleanliness of the writing tool; at the same time, since the pen tip 1 does not directly contact the ruler, it effectively prevents the side wall of the pen tip 1 from being scratched by a hard ruler during use, thereby effectively protecting the pen tip 1 and increasing the durability of the pen tip 1.
[0032] Reference Figure 1 , Figure 2 The radius of the transition portion 11 is larger than the radius of the fixing portion 2. When installing the marker tip, the bottom wall of the transition portion 11 can abut against the end of the pen shell, so that the marker tip is stably fixed to one end of the pen shell, and the marker tip will not retract during writing, thereby ensuring stability during use.
[0033] Reference Figure 1 , Figure 2 The ink guide part 3 is a frustum, and its radius gradually decreases towards the side away from the fixing part 2. Because the radius of the end of the ink guide part 3 away from the fixing part 2 is smaller, it can be ensured that one end of the ink guide part 3 is completely in contact with the ink reservoir core, so that the ink can be smoothly transported from the ink reservoir core to the pen tip 1 through the ink guide part 3, ensuring the continuity and stability of the ink during writing.
[0034] Reference Figure 1 , Figure 2 The writing section 12 is inclined towards the axis of the pen tip 1 to form an anti-scratch surface 121, which forms an angle of 6°-8° with the axis of the pen tip 1. When using the marker with auxiliary tools such as a ruler, the concave anti-scratch surface 121 ensures that there is always a certain gap between the ruler and the pen tip 1, effectively preventing the pen tip 1 from scratching the ruler. This prevents the marker ink from staining the auxiliary tool, reduces the number of times the creation needs to be interrupted due to ink stains, and allows the user to focus more on writing, improving the convenience of use.
[0035] Reference Figure 1 , Figure 2 The writing part 12 is attached to the anti-scratch shell 13 on the side opposite to the anti-scratch surface 121. When using a marker, the rigid anti-scratch shell 13 can provide a certain degree of support. When the pen tip 1 contacts the paper at an angle, the anti-scratch shell 13 can provide a force opposite to the bending direction of the pen tip 1, thereby effectively supporting the pen tip 1 and preventing the pen tip 1 from bending during writing, thus ensuring the stability of writing.
[0036] Reference Figure 1, Figure 2 The writing section 12 has a writing surface 122 on the side facing away from the transition section 11. The writing surface 122 is tilted towards the side closer to the transition section 11, and the tilt angle of the writing surface 122 is 18°-22°. Due to the tilt angle, when writing, the contact area between the writing surface 122 and the paper can be changed by adjusting the angle between the pen tip 1 and the paper, thereby enabling the writing surface 122 to draw lines of different thicknesses and improving the flexibility of use.
[0037] Reference Figure 2 , Figure 3 The writing surface 122 is rounded. When the rounded tip moves across the paper, the contact area is relatively stable, which makes the variation in line thickness more uniform and natural. Especially when drawing curves or filling large areas with color, the shape of the tip will not cause obvious unevenness or bumps in the lines. At the same time, the rounded writing surface 122 makes relatively uniform contact with the paper during use, avoiding excessive wear on the sharp corners, thereby extending the overall lifespan of the tip and effectively improving its service life.
[0038] Reference Figure 2 , Figure 3 The writing surface 12 has inclined surfaces 123 on both sides, which are mirror-symmetrical about the axis, and the included angle between the two inclined surfaces 123 is 30°-40°. When the writing surface 122 contacts the paper, the inclined surfaces 123 on both sides allow the user to swing around the contact surface, making it easier for the user to move the marker laterally and improving the convenience of use; at the same time, the inclined surfaces 123 on both sides prevent the side wall of the pen tip 1 from coming into contact with auxiliary tools such as rulers, effectively preventing ink smudges.
[0039] The implementation principle of a marker tip in this application embodiment is as follows: when the marker is placed close to an auxiliary tool such as a ruler, the anti-scratch shell 13 fixedly connected to the outer periphery of the transition part 11 comes into contact with the auxiliary tool, and the anti-scratch surface 121 of the writing part 12 can always leave a certain gap between the writing part 12 and the auxiliary tool, thereby preventing the pen tip 1 from bringing out ink and staining the auxiliary tool.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
