Description

Technical Field

[0001] This utility model relates to the field of highlighter technology, specifically a cap-replaceable highlighter. Background Technology

[0002] Light pens are markers that have emerged in recent years. They use thicker, lighter ink to cover key areas to make marks, ensuring the marks remain legible without obscuring the text. Highlighters contain fluorescent agents that fluoresce when exposed to ultraviolet light, emitting white light and giving the colors a bright, fluorescent appearance. They are commonly used in offices and for studying.

[0003] According to the search, Chinese patent document, publication number CN220009272U, discloses a cap-replaceable refill highlighter. The refill is designed for easy replacement of the internal highlighter refill. When the highlighter runs out or you want to change the color, you can unscrew the cap, replace the refill, and tighten the cap. It is quick and easy to use, and convenient for outdoor use. The retaining ring and cap work together to ensure that the refill will not loosen after insertion, ensuring smooth writing of the highlighter tip. However, in order to maintain the concept of environmental protection, the replacement refills usually do not include the refill cap and the refill barrel. In addition, a softer refill barrel is used for replacement. The refill cap and refill barrel used are prone to being idle during use, resulting in resource waste. Moreover, when replacing, it is necessary to connect to the pen barrel through the threaded end cap. Frequent replacement and disassembly can easily lead to severe wear of the threads, making it impossible to refill the pen refill. The lifespan is shorter, and the pen tip can easily adhere to new impurities during use due to wear and tear on the paper. If the pen cap does not have a scraping effect, it can easily lead to accelerated wear of the pen tip when used again, and the pen tip will not flow smoothly. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a cap-replaceable highlighter pen that allows for the replacement of traditional pen refills, avoiding resource waste and idleness. It also offers advantages such as high installation stability, long service life, and the ability to remove pen tip impurities, thereby improving the smoothness of pen tip use and solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cap-replaceable highlighter pen, comprising a pen barrel, a pen tip movably mounted on the lower end of the inner side of the pen barrel, a limiting cylinder fixedly mounted on the middle position of the inner side of the pen barrel, a pen refill body movably mounted on the inner side of the limiting cylinder, a positioning groove and an adjustment groove respectively opened on the upper end of the inner side of the pen barrel, a tail cap being snapped onto the upper end of the inner side of the pen barrel, and a pen cap being snapped onto the outer side of the lower end of the pen barrel.

[0008] Preferably, a pen compartment is provided at the lower end of the inner side of the pen barrel, a sliding groove is provided on the inner side of the pen compartment, and a pen hole is provided on the bottom side of the inner side of the pen compartment. A pen tip is movably installed on the inner side of the pen compartment and the pen hole, and two baffles are fixedly installed on the upper end of the inner side of the pen barrel.

[0009] Through the above technical solution, during use, the four sliding grooves inside the pen compartment help to limit and orient the pen tip, while the pen hole facilitates the movement of the pen tip on the bottom side of the pen tip.

[0010] Preferably, the pen tip includes a mating block, a slider, a core rod, and a pen tip. The size and shape of the mating block match the pen compartment, and a slider is fixedly installed on the outer side of the mating block. The slider is movably installed on the inner side of the slide groove. A return spring is fixedly installed between the slide groove and the slider. The core rod and the pen tip are fixedly installed on the top and bottom sides of the mating block, respectively.

[0011] With the above technical solution, during the installation process, the pen refill body moves downward, thereby pushing the mating block, the refill rod, and the pen tip downward. This helps to generate elastic force under the action of the return spring, which in turn makes the pen refill body and the refill rod squeeze and lock together, improving the connection fit. At the same time, it can buffer the pen tip in case it falls during use.

[0012] Preferably, the pen refill body includes a soft shell, an absorbent core, and a first magnet. The absorbent core is provided on the inner side of the soft shell. The lower end of the absorbent core is connected to the core rod by a snap-fit ​​structure, and the first magnet is fixedly installed on the upper end of the inner side of the soft shell.

[0013] With the above technical solution, the use of a traditional pen refill body helps to avoid the waste of resources caused by the idleness of extra parts. At the same time, under the action of the No. 1 magnet, it is easy to pull out the pen refill body, which improves the replacement efficiency and avoids the contamination of fingers by fluorescent liquid.

[0014] Preferably, a retaining plate is fixedly installed on the outer side of the lower end of the tail cover, and a positioning block is fixedly installed on the outer side of the retaining plate. The size and shape of the positioning block match the positioning groove and the adjustment groove. A second magnet is movably installed on the inner side of the tail cover, and a fastening spring is fixedly installed between the second magnet and the tail cover.

[0015] With the above technical solution, during the replacement of the pen refill, the tail cap is rotated 90 degrees, causing the positioning block to rotate inside the adjustment groove and be located at the lower end of the positioning groove. Then, the tail cap is pulled out. At this time, under the action of the second magnet and the first magnet, it is easier to pull out the pen refill body directly, thus avoiding the pen refill body being stuck too tightly and unable to be removed. After the first magnet and the second magnet on the new pen refill body are attracted and fixed, the positioning block is positioned and locked with the positioning groove, and then rotated 90 degrees again, so that the baffle limits the locking plate, thereby achieving the fixing effect.

[0016] Preferably, a fitting sleeve is fixedly installed on the inner side of the pen cap, a plurality of equally spaced scrapers are fixedly installed on the bottom side of the fitting sleeve, and a protective seat is fixedly installed on the bottom side of the inner side of the pen cap, the protective seat being made of rubber material.

[0017] Through the above technical solution, during use, the pen cap is engaged with the lower end of the pen barrel, which helps the protective seat to protect and seal the pen tip on the bottom side of the pen tip. At the same time, during the engagement of the pen tip and the pen cap, the pen tip is squeezed and slid against the elastic multi-set scraper, which helps to scrape away the debris and adhesive impurities generated by friction with the paper on the outside of the pen tip. This helps to improve the lifespan of the pen tip and the smoothness of the next use, and avoids the problem of fingers getting fluorescent liquid from manual wiping. The overall disassembly and use does not easily get fingers dirty.

[0018] Compared with the prior art, this utility model provides a cap-replaceable highlighter pen with the following advantages:

[0019] 1. This utility model rotates the tail cap 90 degrees, causing the positioning block to rotate inside the adjustment groove and be located at the lower end of the positioning groove. Then, the tail cap is pulled out. At this time, under the action of the second magnet and the first magnet, it is easy to pull out the pen refill body directly, thus avoiding the pen refill body being stuck too hard and unable to be removed. After the first magnet and the second magnet on the new pen refill body are attracted and fixed, the positioning block is positioned and locked with the positioning groove and rotated 90 degrees again, so that the baffle limits the locking plate, thereby achieving a fixing effect. Replacement is convenient and simple, while avoiding too many parts being idle and causing resource waste. Moreover, it is beneficial to improve the service life of the connection between the tail cap and the pen barrel.

[0020] 2. In the process of use, this utility model engages the pen cap with the lower end of the pen barrel, which helps the protective seat protect and seal the pen tip on the bottom side of the pen tip. At the same time, during the engagement of the pen tip and the pen cap, the pen tip is squeezed and slid against the elastic multi-set scraper, which helps to scrape away the debris and adhesive impurities generated by friction with the paper on the outside of the pen tip. This helps to improve the service life of the pen tip and the smoothness of the next use, and avoids the problem of fingers getting fluorescent liquid from manual wiping. The overall disassembly and assembly process does not easily get fingers dirty. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figure 1-5 As shown, the present invention provides a cap-replaceable highlighter pen, including a pen barrel 1, a pen tip 2 movably mounted on the lower end of the inner side of the pen barrel 1, a limiting cylinder 3 fixedly mounted on the middle position of the inner side of the pen barrel 1, a pen refill body 4 movably mounted on the inner side of the limiting cylinder 3, a positioning groove 5 and an adjustment groove 6 respectively opened on the upper end of the inner side of the pen barrel 1, a tail cap 7 being snapped on the upper end of the inner side of the pen barrel 1, and a pen cap 8 being snapped on the outer side of the lower end of the pen barrel 1.

[0030] Specifically, a pen compartment 101 is provided at the lower end of the inner side of the pen barrel 1. A sliding groove 102 is provided on the inner side of the pen compartment 101, and a pen hole 103 is provided on the bottom inner side of the pen compartment 101. The pen tip 2 is movably installed inside the pen compartment 101 and the pen hole 103. Two baffles 104 are fixedly installed at the upper end of the inner side of the pen barrel 1. The advantage is that the four sliding grooves 102 on the inner side of the pen compartment 101 are conducive to limiting and orienting the pen tip 2, while the pen hole 103 facilitates the movement of the pen tip 204 on the bottom side of the pen tip 2.

[0031] Specifically, the pen tip 2 includes a mating block 201, a slider 202, a core rod 203, and a pen tip 204. The size and shape of the mating block 201 match the pen compartment 101, and the slider 202 is fixedly installed on the outer side of the mating block 201. The slider 202 is movably installed on the inner side of the slide groove 102, and a return spring is fixedly installed between the slide groove 102 and the slider 202. The core rod 203 and the pen tip 204 are fixedly installed on the top and bottom sides of the mating block 201, respectively. The advantage is that by moving the pen refill body 4 downward during installation, the mating block 201, the core rod 203, and the pen tip 204 are pushed downward, which helps to generate elastic force under the action of the return spring, thereby squeezing and engaging the pen refill body 4 with the core rod 203, improving the connection fit. At the same time, it can buffer the pen tip 204 in case it falls during use.

[0032] Specifically, the pen refill body 4 includes a soft shell 401, an absorbent core 402, and a first magnet 403. The absorbent core 402 is located inside the soft shell 401, and its lower end is engaged with the core rod 203. The first magnet 403 is fixedly installed on the upper end of the inner side of the soft shell 401. The advantages are that using a traditional pen refill body 4 avoids wasting resources by leaving unnecessary parts idle. Furthermore, the first magnet 403 facilitates the removal of the pen refill body 4, improving replacement efficiency and preventing fluorescent liquid from contaminating fingers.

[0033] Example 2:

[0034] like Figure 1-5As shown, as an improvement on the previous embodiment, specifically, a retaining plate 701 is fixedly installed on the outer side of the lower end of the tail cover 7, and a positioning block 702 is fixedly installed on the outer side of the retaining plate 701. The size and shape of the positioning block 702 match the positioning groove 5 and the adjustment groove 6, and a second magnet 703 is movably installed on the inner side of the tail cover 7. A fastening spring is fixedly installed between the second magnet 703 and the tail cover 7. The advantage is that by rotating the tail cap 7 by 90 degrees, the positioning block 702 rotates inside the adjustment groove 6 and is located at the lower end of the positioning groove 5. Then, the tail cap 7 is pulled out. At this time, under the action of the second magnet 703 and the first magnet 403, it is easier to pull out the pen refill body 4 directly, thus avoiding the pen refill body 4 being stuck too hard and unable to be removed. After the first magnet 403 and the second magnet 703 on the new pen refill body 4 are attracted and fixed, the positioning block 702 is positioned and locked with the positioning groove 5 and rotated by 90 degrees again, so that the baffle 104 limits the locking plate 701, thereby achieving the fixing effect.

[0035] Specifically, a fitting sleeve 801 is fixedly installed on the inner side of the pen cap 8, and several equally spaced scrapers 802 are fixedly installed on the bottom side of the fitting sleeve 801. A protective seat 803, made of rubber, is also fixedly installed on the bottom inner side of the pen cap 8. The advantage is that by engaging the pen cap 8 with the lower end of the pen barrel 1, the protective seat 803 effectively protects and seals the pen tip 204 on the bottom side of the pen nib 2. Simultaneously, during the engagement of the pen tip 204 with the pen cap 8, the pen tip 204 slides against the elastic multiple sets of scrapers 802, effectively removing debris and adhesive impurities generated by friction with paper on the outer side of the pen tip 204. This improves the lifespan of the pen tip 204 and the smoothness of subsequent use, avoids manual wiping that could result in fingers being stained with fluorescent liquid, and the overall assembly and disassembly process minimizes the risk of finger contamination.

[0036] When replacing the pen refill, rotate the tail cap 7 90 degrees, causing the positioning block 702 to rotate inside the adjustment groove 6 and position itself at the lower end of the positioning groove 5. Then, pull out the tail cap 7. At this point, the pen refill body 4 can be easily pulled out directly by the action of the second magnet 703 and the first magnet 403, thus avoiding the pen refill body 4 being stuck due to excessive force. After attaching and fixing the first magnet 403 and the second magnet 703 on the new pen refill body 4, position the positioning block 702 and the positioning groove 5, and then rotate it 90 degrees again, so that the baffle 104 limits the locking plate 701, thereby achieving a fixing effect. This method is convenient and simple to use, avoids excessive parts being idle and wasting resources, and also helps to improve the usability of the connection position between the tail cap 7 and the pen barrel 1. The lifespan is extended, and under the action of the spring, it is beneficial to push the second magnet 703 and the pen refill body 4 to engage with the core rod 203 on the top side of the pen tip 2, improving the connection fit and avoiding the phenomenon of interruption. At the same time, during use, by engaging the pen cap 8 with the lower end of the pen barrel 1, it is beneficial for the protective seat 803 to protect and seal the pen tip 204 on the bottom side of the pen tip 2. During the engagement of the pen tip 204 and the pen cap 8, the pen tip 204 is squeezed and slid against the elastic multi-set scraper 802, which is beneficial to scrape off the debris and adhesive impurities generated by friction with the paper on the outside of the pen tip 204, thereby improving the lifespan of the pen tip 204 and the smoothness of the next use. It also avoids the problem of fingers getting stained with fluorescent liquid due to manual wiping, and the overall disassembly and use is not easy to stain fingers.
