Abstract
Description
Technical Field
[0001] This application relates to the technical field of highlighters, and in particular to a pen tip for easy marking and a highlighter having the same pen tip. Background Technology
[0002] A highlighter is a pen used for marking text. It produces a thick, light ink to cover the text without obscuring the original text. The ink in highlighters contains fluorescent agents, which fluoresce when exposed to ultraviolet light, making the ink appear bright and thus ensuring the marked text is clearly visible.
[0003] In related technologies, highlighters generally include a pen tip for writing and a pen body connected to the pen tip. When writing with traditional highlighters, the pen tip applies a lot of pressure to the paper surface. This not only makes it easy to smudge the original ink on the paper, but also makes it easy for ink residue to bleed at the ends of the written words, resulting in low neatness. Therefore, it needs to be improved. Utility Model Content
[0004] To improve the neatness of marking with a highlighter, this application provides a pen tip for easy marking and a highlighter pen having the pen tip.
[0005] Firstly, the pen tip provided in this application for easy marking adopts the following technical solution:
[0006] A pen tip for easy marking includes a writing core and a connector fitted onto the writing core. A pen body is connected to the connector. The writing core includes a cylindrical portion located inside the pen body and a plate-shaped portion capable of contacting paper. The plate-shaped portion is located outside the pen body and is deformable. The connector includes two extensions for limiting the plate-shaped portion. The two extensions are located on both sides of the plate-shaped portion. The maximum distance between the extensions and the pen body is less than the maximum distance between the plate-shaped portion and the pen body.
[0007] By adopting the above technical solution, when using this highlighter for marking, the plate-shaped part can deform when it comes into contact with the paper, so that the entire end of the pen tip can be completely attached to the paper. At the same time, the two extensions limit the plate-shaped part, preventing the plate-shaped part from deforming in the direction of the two extensions. This makes the handwriting and stroke width more stable, and the written lines can cover the text to be marked in one go. In addition, the pressure of the pen tip on the paper is reduced, which reduces the possibility of ink accumulation and bleeding at the end of the handwriting, thereby reducing the risk of ink contamination on the paper. The pen tip is also less likely to damage the original handwriting, improving the neatness of marking with the highlighter.
[0008] Optionally, the connector further includes two fixing plates disposed between the two extensions, with fixing holes formed between the two fixing plates and the two extensions, the plate-shaped portion passing through the fixing holes, and the width of the fixing holes being greater than the width of the plate-shaped portion and less than the diameter of the column-shaped portion.
[0009] By adopting the above technical solution, when the pen refill is connected to the pen body through the connector, the plate-shaped part of the pen refill will be limited to the outside of the pen body, and the cylindrical part will be limited to the inside of the pen body, making it difficult for the pen refill to slip out of the connector. The connection between the pen refill and the pen body is highly stable and the overall integrity of the highlighter is good.
[0010] Optionally, the connector further includes a fastening part disposed on the side of the extension near the pen body. The fastening part is provided with a plurality of clamping pieces on the side away from the extension. Each clamping piece is evenly distributed along the circumference of the fastening part. The clamping pieces are inclined toward the central axis of the fastening part. When the pen refill is inserted into the connector, the clamping pieces can elastically deform in a direction away from the central axis of the fastening part.
[0011] By adopting the above technical solution, when the pen refill is inserted into the connector, the cylindrical part will press the clamping piece away from the central axis of the fastening part, causing the clamping piece to deform away from the central axis of the fastening part. As a result, the cylindrical part will be stably clamped by the clamping piece, so that the position of the pen refill is fixed relative to the connector, and the connection stability between the pen refill and the pen body is high.
[0012] Optionally, a plurality of reinforcing blocks are provided on the circumferential sidewall of the fastening part, and the reinforcing blocks are disposed between the clamping piece and the extension.
[0013] By adopting the above technical solution, the reinforcing block can increase the sidewall thickness of the connector, thereby enhancing the structural strength and rigidity of the connector and extending its service life.
[0014] Optionally, a plurality of limiting blocks are provided on the inner sidewall of the pen body. The limiting blocks are evenly distributed along the circumference of the pen body, and a limiting groove is formed between two adjacent limiting blocks. The limiting groove is interference-fitted with the reinforcing block.
[0015] By adopting the above technical solution, when the connector is connected to the pen body, the interference fit between the reinforcing block and the limiting groove makes the connection strength between the connector and the pen body high, and the connector is not easy to separate from the pen body during use, thus making the highlighter pen have good integrity.
[0016] Optionally, the connector may further include an extension ring disposed between the fastening portion and the extension portion, wherein the outer diameter of the extension ring is larger than the inner diameter of the pen body.
[0017] By adopting the above technical solution, when the connector is connected to the pen body, the extension ring can limit the extension to the outside of the pen body, so that the extension will not slide to the inside of the pen body when writing, which helps to ensure the normal use of the highlighter.
[0018] Optionally, the extension ring includes an outer ring and an inner ring, the outer ring is disposed outside the inner ring, the extension portion and the fixing piece are disposed on the inner ring, the fastening portion is disposed on the outer ring, and the outer ring and the inner ring are detachably connected.
[0019] By adopting the above technical solution, when it is necessary to replace the pen refills with different widths, the connector can be separated from the pen body first, then the inner ring can be removed from the outer ring, and the original pen refill can be removed from the outer ring to facilitate the installation of pen refills with different widths in the outer ring. After the pen refills are installed, the inner ring with extensions of different spacing can be installed on the outer ring to fix the pen refills of different widths. By replacing pen refills with different widths in the above way, the highlighter can draw lines of different widths, and the pen refill width can be changed according to the size of the text to be marked. Alternatively, the inner ring with extensions of different lengths can be replaced in the above way. The shorter the extension, the greater the deformation of the plate, and thus the larger the area in contact with the paper, and the darker the line color. Users can adjust the degree of deformation of the plate according to their needs, making the use of the highlighter flexible.
[0020] Optionally, the outer ring has a plurality of mounting grooves on its circumferential inner wall, and the inner ring has a plurality of mounting blocks on its circumferential outer wall, wherein the mounting blocks are interference-fitted with the mounting grooves.
[0021] By adopting the above technical solution, the inner ring and the outer ring are connected together by the interference fit of the mounting block and the mounting groove, which makes the connection strength between the inner ring and the outer ring high, and facilitates the disassembly of the inner ring and the outer ring. It also makes the structure of the connector simple and easy to process.
[0022] Secondly, the highlighter provided in this application adopts the following technical solution:
[0023] Optionally, a highlighter includes a pen tip for marking as described in any of the preceding items.
[0024] By adopting the above technical solution, when using this highlighter, the pen tip does not apply excessive pressure to the paper, thus preventing the pen tip from wearing away the original writing and reducing ink bleeding on the paper, resulting in clean markings. The two extensions can limit the plate shape, making the stroke width stable and facilitating marking.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. The plate shape can deform, which reduces the pressure of the pen lead on the paper, making it less likely to damage the original writing and less likely to bleed ink. The two extensions can limit the plate shape, making the stroke width stable and improving the neatness of marking with a highlighter.
[0027] 2. The connector ensures high stability in the connection between the pen tip and the pen body, thereby enhancing the overall structural stability of the highlighter. Attached Figure Description

Detailed Implementation
[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0035] This application discloses a pen tip for easy marking and a highlighter pen having the pen tip.
[0036] Example 1
[0037] Reference Figure 1 The highlighter pen includes a pen body 2 and a pen tip 4. The pen tip 4 includes a writing core 1 and a connector 3 fitted onto the writing core 1. The connector 3 is connected to the pen body 2. The pen body 2 is a hollow tubular structure, with the end of the pen body 2 without the connector 3 closed. The writing core 1 is made of nylon fiber, which has good extensibility and flexibility. It can deform when in contact with paper, thereby reducing the pressure exerted by the writing core 1 on the paper and making it less likely to damage the original writing.
[0038] Reference Figure 1 and Figure 2The pen refill 1 includes a cylindrical portion 11 located inside the pen body 2 and a plate-shaped portion 12 that can contact the paper. When assembled, the plate-shaped portion 12 is located outside the pen body 2. The maximum distance between the extension portion 31 and the pen body 2 is less than the maximum distance between the pen refill 1 and the pen body 2. The cross-section of the plate-shaped portion 12 is preferably a parallelogram. The plate-shaped portion 12 is located outside the pen body 2 and can deform. In this embodiment, the thickness of the plate-shaped portion 12 is preferably gradually thinner from the direction close to the connector 3 to the direction away from the connector 3, and the end of the plate-shaped portion 12 that contacts the paper is the thinnest. With this design, the pen refill 1 can draw finer lines, thereby meeting the different marking needs of users. In other cases, the specific shape of the plate-shaped portion can also be designed according to customer needs.
[0039] Reference Figure 2 The connector 3 includes two extensions 31 for limiting the plate-shaped part 12, a fastening part 37 disposed on the side of the extension 31 near the pen body 2, a plurality of clamping pieces 34 disposed on the side of the fastening part 37 away from the extension 31, and an extension ring 35 disposed between the fastening part 37 and the extension 31. The two extensions 31 are disposed on both sides of the plate-shaped part 12, and two parallel fixing pieces 32 are fixed between the two extensions 31. The two fixing pieces 32 and the two extensions 31 form a fixing hole 33. The plate-shaped part 12 passes through the fixing hole 33. The width of the fixing hole 33 is greater than the width of the plate-shaped part 12 and less than the diameter of the column-shaped part 11.
[0040] Reference Figure 2 Each clamping piece 34 is evenly distributed circumferentially along the fastening part 37. In this embodiment, the number of clamping pieces 34 is preferably four, but the specific number can be selected according to customer needs in other cases. The clamping pieces 34 are inclined towards the central axis of the fastening part 37, and when the pen refill 1 passes through the connector 3, the clamping pieces 34 can elastically deform in a direction away from the central axis of the fastening part 37. With the above arrangement, the cylindrical part 11 of the pen refill 1 is fixed in the connector 3, so that the connection stability between the pen refill 1 and the connector 3 is high.
[0041] Reference Figure 1 and Figure 2 The extension portion 31 is disposed on the extension ring 35, and the fastening portion 37 is disposed on the side of the extension ring 35 away from the extension portion 31, and the outer diameter of the extension ring 35 is larger than the inner diameter of the pen body 2. When the connector 3 is connected to the pen body 2, the extension ring 35 is blocked on the outside of the pen body 2, thereby limiting the plate-shaped portion 12 and the extension portion 31 on the outside of the pen body 2, which helps to ensure the normal use of the highlighter.
[0042] Reference Figure 2 and Figure 3A plurality of reinforcing blocks 36 are fixed on the circumferential sidewall of the fastening part 37. The reinforcing blocks 36 are evenly distributed along the circumferential sidewall of the connector 3 and are positioned between the clamping piece 34 and the extension ring 35. A plurality of limiting blocks 21 are provided on the inner sidewall of the pen body 2. The limiting blocks 21 are evenly distributed along the circumference of the pen body 2, and a limiting groove 22 is formed between two adjacent limiting blocks 21. The limiting groove 22 and the reinforcing block 36 are interference-fitted. The number of limiting grooves 22 and the reinforcing blocks 36 are equal and correspond one-to-one. In this embodiment, the number of both reinforcing blocks 36 and limiting blocks 21 is preferably 4. In other cases, the specific number can be selected according to customer needs. Through the above settings, the connector 3 and the pen body 2 are connected together by the interference fit between the reinforcing blocks 36 and the limiting grooves 22, which makes the connection strength between the connector 3 and the pen body 2 high and makes the structure of the connector 3 simple and easy to disassemble.
[0043] The implementation principle of the marker tip and the highlighter pen with the marker tip in this application embodiment is as follows: During assembly, the connector 3 is first fitted onto the pen refill 1, so that the plate-shaped part 12 passes through the fixing hole 33 and the cylindrical part 11 is clamped by the clamping piece 34. Then, the end of the connector 3 with the clamping piece 34 extends into the inside of the pen body 2, so that the reinforcing block 36 extends into the limiting groove 22, thereby connecting the pen refill 1 and the pen body 2 together. In use, the pen refill 1 can deform when it is in contact with the paper, thereby reducing the pressure applied to the paper and reducing the possibility of the pen refill 1 damaging the original writing, thus improving the neatness and convenience of marking with the highlighter pen. At the same time, the two extensions 31 can limit the plate-shaped part 12, so that the stroke width is stable.
[0044] Example 2
[0045] Reference Figure 2 and Figure 4 The difference between this embodiment and Embodiment 1 is that: the extension ring 35 includes an inner ring 353 and an outer ring 351. The outer ring 351 is disposed outside the inner ring 353. The extension part 31 and the fixing piece 32 are disposed on the inner ring 353. The fastening part 37 is disposed on the outer ring 351. A plurality of mounting blocks 354 are fixed on the circumferential outer wall of the inner ring 353. The circumferential inner wall of the outer ring 351 is provided with mounting grooves 352 that are equal in number and correspond one-to-one with the mounting blocks 354. In this embodiment, the number of mounting blocks 354 and mounting grooves 352 is preferably 4. The inner ring 353 and the outer ring 351 are detachably connected by the interference fit between the mounting blocks 354 and the mounting grooves 352. The inner sidewalls of the two extensions 31 are provided with fixing grooves 311 for the edge of the plate-shaped part 12 to extend into. The fixing grooves 311 can limit the deformation length of the plate-shaped part 12, so that the plate-shaped part 12 located in the fixing grooves 311 cannot deform. Therefore, the shorter the length of the extension 31, the greater the degree of deformation of the plate-shaped part 12.
[0046] The implementation principle of the pen tip for easy marking and the highlighter pen with the pen tip in this application embodiment is as follows: when it is necessary to adjust the degree of deformation of the pen tip 1 or the width of the stroke, the maximum degree of deformation of the plate-shaped part 12 can be changed by replacing the inner ring 353 with extensions 31 of different lengths, or the inner ring 353 with extensions 31 of different spacings can be replaced to install pen tips 1 of different widths, so that the highlighter pen can be used in various scenarios and meet the different marking needs of users.
[0047] 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.
