Abstract
Description
Technical Field
[0001] This utility model relates to the field of marker pens, and more specifically, to a refillable ink marker pen. Background Technology
[0002] A marker pen is a colored pen used for writing or drawing. It contains ink and usually has a cap, typically with a hard nib. Its ink is volatile, allowing for quick, one-time drawing. It is commonly used for designing objects, advertising slogans, posters, and other artistic creations. Markers come in oil-based, water-based, and alcohol-based varieties, and are characterized by bright colors, easy application, clear strokes, and portability.
[0003] The existing marker caps are not easy to open, making it difficult to add ink. Also, the caps can become loose after repeated insertion and removal, making them prone to falling off. Furthermore, the nibs can develop burrs after prolonged use, making nib replacement inconvenient.
[0004] Therefore, we made improvements and proposed a refillable ink marker. Utility Model Content
[0005] The purpose of this invention is to address the problem that the cap on the top of existing marker pens is inconvenient to open, making it difficult to add ink. Furthermore, the cap may loosen after prolonged use, causing it to fall off easily. Additionally, the pen tip may develop burrs after long-term use, making it inconvenient to replace.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] Refillable markers can improve the above problems.
[0008] The application is as follows:
[0009] The pen includes a pen barrel, a tail cap threaded to the top of the pen barrel, two semicircular blocks fixedly connected to the tail cap, a slot between the two semicircular blocks, a connector threaded to the bottom of the pen barrel, a writing mechanism on the connector, a pen cap on the outer wall of the connector, an opening protrusion integrally formed on the pen cap, and a connecting mechanism on the pen cap.
[0010] As a preferred technical solution of this application, the writing mechanism includes a pen tip disposed at the bottom of the connector.
[0011] As a preferred technical solution of this application, the connecting mechanism includes a magnetic ring fixedly connected to the top of the pen cap, and an iron ring fixedly connected to the pen barrel, the iron ring cooperating with the magnetic ring.
[0012] As a preferred technical solution of this application, the outer wall of the pen barrel is fitted with an anti-slip rubber sleeve.
[0013] As a preferred technical solution of this application, the top of the pen barrel is provided with a first external thread, and the bottom of the pen barrel is provided with a second external thread.
[0014] As a preferred technical solution of this application, the tail cover is provided with a first internal thread, which is engaged with a first external thread.
[0015] As a preferred technical solution of this application, the connector is provided with a second internal thread, which mates with a second external thread.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] In the scheme of this application:
[0018] 1. By inserting the opening protrusion on the pen cap between the two semicircular blocks, and then rotating the pen cap, the pen cap drives the opening protrusion to rotate, which in turn drives the semicircular blocks, which in turn drive the tail cap to rotate, thus removing the tail cap. This makes it easy to open the tail cap and add ink, solving the problem that the tail cap at the top of the marker pen is inconvenient to open, which makes it difficult to add ink.
[0019] 2. By incorporating a magnetic ring and an iron ring, the problem of pen caps loosening after prolonged insertion and removal, leading to loose caps and easy detachment, is solved in existing technologies.
[0020] 3. The detachable pen tip allows for easy replacement, solving the problem of burrs forming on the pen tip after prolonged use in existing technologies, which makes pen tip replacement inconvenient. Attached Figure Description

These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0035] Example:
[0036] like Figure 1-7 As shown, this embodiment proposes a refillable ink marker, including a pen barrel 1. The top of the pen barrel 1 is threadedly connected to a tail cap 2. Two semicircular blocks 3 are fixedly connected to the tail cap 2. A slot is reserved between the two semicircular blocks 3. The bottom of the pen barrel 1 is threadedly connected to a connector 4. A writing mechanism is provided on the connector 4. A pen cap 5 is provided on the outer wall of the connector 4. An opening protrusion 6 is integrally formed on the pen cap 5. A connecting mechanism is provided on the pen cap 5.
[0037] The writing mechanism includes a pen tip 14 located at the bottom of the connector 4. The pen tip 14 is inserted into the connector 4. When the connector 4 is connected to the pen barrel 1, the ink in the pen barrel 1 can be introduced into the pen tip 14 to achieve smooth writing. The pen tip 14 can be made of a fibrous pen tip that can achieve writing in the existing technology, such as fiber hair, polyester fiber hair and nylon fiber hair.
[0038] To prevent the pen cap 5 from becoming loose, the connecting mechanism includes a magnetic ring 12 fixedly connected to the top of the pen cap 5, and an iron ring 13 fixedly connected to the pen barrel 1, with the iron ring 13 cooperating with the magnetic ring 12.
[0039] To prevent the hand from slipping when holding the pen, an anti-slip rubber sleeve 7 is provided on the outer wall of the pen barrel 1.
[0040] A first external thread 8 is formed at the top of the pen barrel 1, and a second external thread 10 is formed at the bottom of the pen barrel 1.
[0041] To facilitate the addition of magic, a first internal thread 9 is provided inside the tail cap 2, which mates with the first external thread 8.
[0042] To facilitate the replacement of the pen tip 14, a second internal thread 11 is provided in the connector 4, which mates with the second external thread 10.
[0043] Specifically, when using this refillable marker pen: to adjust the ink level, remove the cap 5, insert the opening protrusion 6 on the cap 5 between the two semicircular blocks 3, then rotate the cap 5. The cap 5 drives the opening protrusion 6 to rotate, which in turn drives the semicircular blocks 3, which in turn drives the tail cap 2 to rotate, allowing the tail cap 2 to be removed for easy opening and ink addition. When the nib 14 becomes fuzzy after prolonged use and affects writing, simply remove the threaded connector 4 for easy replacement of the nib 14. Furthermore, when the cap 5 is closed, the magnetic ring 12 will attract the iron ring 13, preventing the cap 5 from becoming loose. The marker pen of this application can use the opening protrusion 6 on the cap 5 to open the tail cap 2 for easy ink addition to the pen body 1. Moreover, the cap 5 is not easy to fall off after being closed, and it is also convenient to replace the nib 14.
[0044] All technical features in this embodiment can be freely combined according to actual needs.
[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
