Description

Technical Field

[0001] This utility model relates to the field of fiber marker tip technology; more specifically, it relates to an antibacterial fiber marker tip. Background Technology

[0002] The fiber marker tip is made of dense bundles of synthetic fibers with a core structure that has porous capillary properties. It can efficiently absorb and continuously release ink, ensuring smooth and uninterrupted writing. Its fiber material gives it excellent abrasion resistance and impact resistance, making it especially suitable for marking on rough surfaces, while also storing a sufficient amount of ink.

[0003] Currently, existing fiber marker tips have several drawbacks during use. These tips are prone to damage, and the relatively fixed structure of most existing devices makes quick and easy replacement of individual tips inconvenient, reducing the device's practicality. Furthermore, when multiple people share the device, bacteria can be transferred directly from the tip to the next user's hands or object surfaces, potentially causing outbreaks in hospitals, schools, and other similar settings. In addition, microbial growth accelerates tip deterioration, and mold growth leads to mildew spots or odors, severely shortening the tip's lifespan and further diminishing the device's usability. Therefore, there is an urgent need for an antibacterial fiber marker tip to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an antibacterial fiber marker tip to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an antibacterial fiber marker tip, comprising:

[0006] A pen holder, wherein a pen tip body is inserted into the inner surface of the outer surface of one end of the pen holder, and a detachable structure is provided between the inner surface of one end of the pen holder and the outer surface of the pen tip body, and a protective structure is provided at one end of the pen holder.

[0007] The disassembly and assembly structure includes a connecting groove, which is located inside the outer surface of one end of the pen holder.

[0008] The protective structure includes a pen cap, which is threaded onto the outer surface of one end of the pen holder.

[0009] Preferably, the disassembly and assembly structure further includes a movable groove, and there are two sets of movable grooves. The two sets of movable grooves are respectively opened inside the inner wall surface of the upper and lower ends of the connecting groove. An insertion rod is fixedly connected to the outer surface of the pen tip body, and a positioning block is fixedly connected to the outer surface of the upper and lower ends of the insertion rod. An operation groove is opened inside the inner wall surface of the inner end of the connecting groove, and a spring is fixedly connected to the inner wall surface of the inner end of the operation groove. A limit block is fixedly connected to the outer surface of the outer end of the insertion rod. This design allows the insertion rod to move inside the connecting groove.

[0010] Preferably, the internal dimensions of the connecting groove are adapted to the external dimensions of the insertion rod, and the internal dimensions of the moving groove are adapted to the external dimensions of the positioning block. This design makes the insertion rod more stable when moving inside the connecting groove.

[0011] Preferably, the other end of the spring abuts against the outer surface of the two sets of positioning blocks. The external dimensions of the positioning blocks are adapted to the internal dimensions of the operating groove, and the external dimensions of the limiting block are larger than the internal dimensions of the connecting groove. This design can support and press the positioning blocks by the elasticity of the spring itself, and can position the positioning blocks.

[0012] Preferably, the protective structure further includes a storage groove, which is located inside the pen cap. A protective layer is fixedly connected inside the storage groove and is fitted onto the outer surface of the pen tip body. This design allows the pen tip body to be protected by the protective layer when the pen cap is threadedly connected to the pen barrel.

[0013] Preferably, the protective layer is made of polypropylene, and the pen tip body is made of nanocomposite material. Both the protective layer and the pen tip body are coated with quaternary ammonium salt, and the internal dimensions of the protective layer are adapted to the external dimensions of the pen tip body. This design can provide more antibacterial active sites by utilizing the huge specific surface area of ​​the pen tip body material, effectively improving the antibacterial performance of the pen tip.

[0014] The technical effects and advantages of this utility model are as follows: This utility model inserts the pen tip body into the interior of one end of the pen holder, and drives the insertion rod and positioning block to be inserted into the interior of the connecting groove and the moving groove respectively. After the positioning block is moved into the interior of the operating groove, rotating the insertion rod can drive the positioning block to rotate inside the operating groove. Through the elasticity of the spring itself, the positioning block can be supported and pressed, so that the outer surface of the positioning block is pressed against the inner wall surface of the operating groove, thereby positioning the pen tip body. This allows for quick installation of the pen tip body. When rotating the insertion rod, the positioning block is rotated to correspond to the position of the moving groove. Through the elasticity of the spring itself, the positioning block can be automatically moved outward inside the moving groove, and the pen tip body can be detached from the interior of one end of the pen holder. This allows for quick disassembly of the pen tip body, and quick replacement when the pen tip is damaged, thus improving the practicality of the equipment to a certain extent.

[0015] By rotating the pen cap threaded onto the outer surface of one end of the pen barrel, the protective layer can be fitted onto the outer surface of the pen tip. The antibacterial properties of the protective layer material itself prevent bacteria from growing in a damp and enclosed environment when the pen tip is inserted into the pen cap. At the same time, the large specific surface area of ​​the pen tip material itself can further enhance the antibacterial performance of the pen tip, preventing group infections in hospitals or schools. It can also prevent mold growth, mold spots, or odors that would shorten the life of the pen tip, thus improving the practicality of the device to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The fiber marker tip involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0022] like Figure 1 and Figure 2 As shown, this embodiment proposes an antibacterial fiber marker tip, comprising:

[0023] Pen holder 1, pen tip body 2 is inserted into the inner surface of the outer surface of one end of pen holder 1, and a disassembly structure 3 is provided between the inner surface of one end of pen holder 1 and the outer surface of pen tip body 2, and a protective structure 4 is provided at one end of pen holder 1.

[0024] The disassembly and assembly structure 3 includes a connecting groove 31, which is located inside the outer surface of one end of the pen holder 1. The disassembly and assembly structure 3 also includes a movable groove 32, which is provided in two sets. The two sets of movable grooves 32 are respectively located inside the inner wall surfaces of the upper and lower ends of the connecting groove 31. An insertion rod 33 is fixedly connected to the outer surface of the pen tip body 2, and a positioning block 34 is fixedly connected to the outer surface of both the upper and lower ends of the insertion rod 33. The internal dimensions of the connecting groove 31 are adapted to the external dimensions of the insertion rod 33, and the internal dimensions of the movable groove 32 are adapted to the external dimensions of the positioning block 34. This design allows the insertion rod 33 to move inside the connecting groove 31, and the insertion rod 33 can move more stably. At the same time, it can drive the positioning block 34 to move inside the movable groove 32, and the positioning block 34 can move more stably inside the movable groove 32.

[0025] An operating groove 35 is formed on the inner wall surface of the inner end of the connecting groove 31, and a spring 36 is fixedly connected to the inner wall surface of the inner end of the operating groove 35. A limiting block 37 is fixedly connected to the outer surface of the outer end of the insertion rod 33. The other end of the spring 36 abuts against the outer surface of two sets of positioning blocks 34. The external dimensions of the positioning blocks 34 are adapted to the internal dimensions of the operating groove 35, and the external dimensions of the limiting block 37 are larger than the internal dimensions of the connecting groove 31. This design, through the elasticity of the spring 36 itself, can press the positioning blocks 34 together. When the positioning blocks 34 are inside the operating groove 35, the outer surface of the positioning blocks 34 can be pressed against the inner wall surface of the operating groove 35, thereby positioning the position of the positioning blocks 34. At the same time, it can make the positioning blocks 34 more stable inside the operating groove 35. By the mutual abutment between the outer surfaces of the limiting block 37 and the pen holder 1, the positioning blocks 34 can be prevented from shaking inside the operating groove 35, thereby making the pen tip body 2 more stable inside the pen holder 1. Example 2

[0026] like Figure 3 and Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0027] The protective structure 4 includes a pen cap 41, which is threaded to the outer surface of one end of the pen barrel 1. The protective structure 4 also includes a storage groove 42, which is opened inside the pen cap 41. A protective layer 43 is fixedly connected inside the storage groove 42, and the protective layer 43 is sleeved on the outer surface of the pen tip body 2. The protective layer 43 is made of polypropylene, and the pen tip body 2 is made of nanocomposite material. Both the protective layer 43 and the pen tip body 2 are coated with quaternary ammonium salt, and the internal dimensions of the protective layer 43 are adapted to the external dimensions of the pen tip body 2.

[0028] In this embodiment, the pen cap 41 is threaded to the outer surface of one end of the pen barrel 1, allowing the protective layer 43 to cover the pen tip body 2. This ensures a more complete cover for the pen tip body 2, preventing contamination from external bacteria. The large specific surface area of ​​the pen tip body 2 provides more antibacterial active sites, effectively improving its antibacterial performance. Furthermore, the antibacterial properties of the protective layer 43 and the positive charge of the quaternary ammonium salt coating disrupt bacterial cell membranes, resulting in physical sterilization without the risk of drug resistance, further enhancing the device's antibacterial performance.

[0029] Working principle: When using the equipment, first insert the pen tip body 2 into the interior of one end of the pen holder 1, and drive the insertion rod 33 and the positioning block 34 to be inserted into the interior of the connecting groove 31 and the moving groove 32 respectively. After moving the positioning block 34 into the interior of the operating groove 35, rotate the insertion rod 33 to offset the position of the positioning block 34 from the position of the moving groove 32. At the same time, the spring 36 supports the positioning block 34 through its own elasticity, so that the positioning block 34 can be pressed against the inner wall surface of the operating groove 35, and the pen tip body 2 can be quickly installed.

[0030] After writing is finished, first rotate the pen cap 41 and thread it onto the outer surface of one end of the pen holder 1. The pen tip body 2 will then be completely wrapped by the protective layer 43, protecting it from external bacteria contamination. This is the complete working principle of this device.

[0031] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
