Description

Technical Field

[0001] This utility model relates to the field of fiber pen tip technology; more specifically, it relates to a fiber pen tip that is easy to disassemble. Background Technology

[0002] Fiber pens are characterized by their nibs made of fiber material, which provides excellent elasticity and durability. They are commonly used for writing, drawing, marking, and many other purposes, due to their fine nib, clear lines, and rich colors.

[0003] Currently, existing fiber pen tips typically connect to the pen body via a threaded connection. While this provides good stability, disassembly or installation requires several rotations of the pen tip, making the connection cumbersome and slow, thus reducing the device's practicality. Furthermore, users may pause writing for extended periods, causing the pen tip to come into contact with the paper, leaving marks and affecting writing quality. After use, the cap is typically placed on the pen tip for sealing, but residual ink can drip inside the cap, affecting future use and further compromising the device's usability. Therefore, there is an urgent need for a fiber pen tip that is easy to disassemble to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fiber pen tip that is easy to disassemble, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a fiber pen tip that is easy to disassemble, comprising:

[0006] The pen tip body has an auxiliary structure on its outer surface, and an insertion round plate is fixedly connected to one end of the pen tip body. A pen barrel is fitted on the outer surface of the insertion round plate. The pen barrel has a detachable structure inside, and a pen cap is fitted on one end of the pen barrel.

[0007] The auxiliary structure includes a pen sleeve, which is fitted onto the outer surface of the pen tip body.

[0008] The disassembly structure includes an insertion slot and an insertion block, with the insertion slot located inside the other side of the pen barrel.

[0009] Preferably, the outer surface of the pen tip body is covered with a rubber pad, which can improve the user's comfort.

[0010] Preferably, the auxiliary structure further includes an auxiliary plate, and the bottom surface of the auxiliary plate is fixedly connected to the top of the outer surface of the pen cap. A support plate is fixedly connected to one side of the bottom of the outer surface of the pen cap, and the support plate has a groove inside. This design can seal and protect the pen tip body under the action of the pen cap, preventing the pen tip body from drying out due to prolonged contact with air.

[0011] Preferably, the disassembly structure further includes an arc groove, which is formed on one side inside the insertion slot. A spring is fixedly connected inside the arc groove, and one end of the spring is fixedly connected to an arc plate. A pull rod is fixedly connected to the end of the outer surface of the arc plate away from the spring, and one end of the pull rod passes through and extends out of the interior of the arc groove. An insertion block is fixedly connected to one side of the outer surface of the insertion plate, and the insertion block is inserted into the interior of the insertion slot. A through groove is formed on one side of the interior of the insertion block. This design can locate the position of the insertion plate after installation.

[0012] Preferably, the internal dimensions of the insertion slot are adapted to the external dimensions of the insertion block, which allows the insertion block to move smoothly inside the insertion slot.

[0013] Preferably, the interior of both the arc groove and the through groove is circular, and the internal dimensions of the arc groove and the through groove are adapted to the external dimensions of the arc plate. This design allows the arc plate to move in close contact with the inner wall of the arc groove.

[0014] The technical effects and advantages of this utility model are as follows: By pulling the lever, when the pulling force is greater than the elastic force of the spring, the arc plate can be moved back inside the arc groove until the arc plate is disengaged from the insertion groove. Then, the insertion block is aligned with the insertion groove and inserted. At this time, the insertion plate is inserted into the pen barrel. When the insertion block moves to the bottom of the inner wall of the insertion groove, the lever can be released, and the arc plate is ejected outward under the elastic force of the spring. At this time, the arc plate will move out of the arc groove and be inserted into the through groove. This design can position the insertion plate inside the pen barrel and facilitate the user to quickly install and disassemble it. Compared with the traditional threaded connection method, it is faster and more convenient to disassemble, which improves the practicality of the equipment to a certain extent.

[0015] By removing the pen cap from the outer surface of the pen tip, the entire auxiliary structure can be flipped over. With the auxiliary plate placed on a table, the groove faces upwards. This design, aided by the auxiliary plate, ensures stability of the groove and support plate when facing upwards. The groove also allows the user to easily place the pen tip inside, preventing ink marks from the paper surface. This makes it convenient to use. After use, the pen cap can be slipped over the outside of the pen tip, creating a seal. When the support plate is in contact with the table, the pen tip is tilted, preventing ink from dripping into the pen cap and keeping it clean. This also prevents ink buildup inside the pen cap from affecting future use, improving the device's practicality. Furthermore, its simple and reasonable overall design makes it 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 pen 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 easily detachable fiber pen tip, comprising:

[0023] The pen tip body 1 has an auxiliary structure 2 on its outer surface, and an insertion round plate 3 is fixedly connected to one end of the pen tip body 1. A pen barrel 4 is fitted on the outer surface of the insertion round plate 3. A disassembly structure 5 is provided inside the pen barrel 4, and a pen cap 6 is fitted on one end of the pen barrel 4.

[0024] The outer surface of the pen tip body 1 is covered with a rubber pad. This design, with the softness of the rubber pad itself, can improve the comfort of the fingers when the user pinches the pen tip body 1 to write.

[0025] The auxiliary structure 2 includes a pen sleeve 21, which is fitted onto the outer surface of the pen tip body 1. The auxiliary structure 2 also includes an auxiliary plate 22, the bottom surface of which is fixedly connected to the top of the outer surface of the pen sleeve 21. A support plate 23 is fixedly connected to one side of the bottom of the outer surface of the pen sleeve 21, and a groove 24 is provided inside the support plate 23. When the groove 24 faces upward, this design can form a placement platform, which makes it easy to place the pen tip body 1 inside the groove 24. At the same time, the groove 24 is arc-shaped, which can prevent the pen tip body 1 from falling out of the groove 24 due to slight shaking. 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 disassembly structure 5 includes an insertion slot 51 and an insertion block 56. The insertion slot 51 is located inside the other side of the pen barrel 4. The disassembly structure 5 also includes an arc groove 52, which is located inside the insertion slot 51. A spring 53 is fixedly connected inside the arc groove 52, and an arc plate 54 is fixedly connected to one end of the spring 53. A pull rod 55 is fixedly connected to the end of the outer surface of the arc plate 54 away from the spring 53, and one end of the pull rod 55 passes through and extends out of the interior of the arc groove 52. An insertion block is fixedly connected to one side of the outer surface of the insertion plate 3. A block 56 is provided, and the insertion block 56 is inserted into the insertion slot 51. A through slot 57 is provided on one side of the insertion block 56. Under the elastic action of the spring 53, the arc plate 54 can be automatically reset, so that the arc plate 54 can be stably inserted into the through slot 57, thereby positioning the insertion plate 3. This ensures that the insertion plate 3 is always installed in the same position inside the pen barrel 4, making it easier for the user to accurately contact the insertion plate 3 when adding a new ink cartridge, thus improving the overall ease of operation and accuracy.

[0028] The internal dimensions of the insertion slot 51 are adapted to the external dimensions of the insertion block 56. This design allows the insertion block 56 to be accurately inserted into the insertion slot 51 and the insertion disc 3 to be accurately inserted into the pen barrel 4.

[0029] The interiors of both the arc groove 52 and the through groove 57 are circular, and the internal dimensions of the arc groove 52 and the through groove 57 are adapted to the external dimensions of the arc plate 54. This design allows the arc plate 54 to move tightly against the inner wall of the arc groove 52 when it is subjected to the elastic force of the spring 53, and allows the arc plate 54 to be accurately inserted into the interior of the through groove 57.

[0030] Working principle: When the device is in use, by pulling the lever 55, when the pulling force is greater than the elastic force of the spring 53, the arc plate 54 can be moved back inside the arc groove 52 until the arc plate 54 is disengaged from the insertion groove 51. Then, the insertion block 56 is inserted into the insertion groove 51. At this time, the insertion round plate 3 is inserted into the pen barrel 4. When the insertion block 56 moves to the bottom of the inner wall of the insertion groove 51, the lever 55 can be released, and the arc plate 54 will be ejected outward under the elastic force of the spring 53. At this time, the arc plate 54 will be moved out of the arc groove 52 and inserted into the through groove 57. This design can be used to position the insertion round plate 3 after installation. After use, the above operation can be repeated to remove the arc plate 54 from the through groove 57, thereby canceling the positioning effect of the insertion round plate 3 and making it convenient for the user to disassemble the pen head body 1.

[0031] When using the device, first remove the pen cap 21 from the outer surface of the pen tip body 1, then the pen tip body 1 can be used. At this time, the pen cap 21 can be flipped over so that the auxiliary plate 22 is placed on the table with the groove 24 facing upwards. Under the action of the auxiliary plate 22, the groove 24 and the support plate 23 remain stable when facing upwards. Under the action of the groove 24, it is easy for the user to place the pen tip body 1 inside the groove 24, avoiding the situation of leaving marks on the paper surface due to the pen being placed there. It is more convenient to use. After use, the pen cap 21 can be removed again. Flip it over once and place the pen cap 21 on the outside of the pen tip body 1 to form a seal, preventing the pen tip body 1 from drying out due to prolonged contact with air. Under the support of the support plate 23, the pen tip body 1 can form a certain tilt inside the pen cap 21, which can prevent ink from dripping from the surface of the pen tip body 1 into the pen cap 21 to a certain extent, keeping the inside of the pen cap 21 clean and tidy. It also prevents the pen cap 21 from having a lot of ink inside, which would affect the next use. The above is the entire working principle of this utility model.
