Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and more specifically to a fountain pen nib and fountain pen with adjustable ink flow. Background Technology

[0002] Fountain pens, as a traditional writing tool, are widely used due to their smooth writing, clear handwriting, and certain artistic appeal. However, as people's demands for a better writing experience continue to rise, some technical problems have gradually emerged in the use of traditional fountain pens:

[0003] Traditional fountain pens typically have a fixed ink flow rate, which cannot be adjusted according to the user's writing needs (such as thick or thin lines). For example, when writing thick lines, the ink flow may be insufficient, resulting in broken lines; while when writing thin lines, the ink flow may be excessive, easily causing ink bleeding. This ink flow design, which cannot adapt to different writing needs, affects the smoothness and quality of writing.

[0004] While some existing technologies attempt to address the ink flow adjustment problem, these designs often suffer from structural complexity and cumbersome operation. For example, in the prior art with patent number 202311222309.0, the pen tip includes a feed, a nib, and a nib. The ink flow is altered by adjusting the ink slit width through screws and multiple adjustment holes. However, this design requires the user to precisely operate multiple screws during adjustment, increasing the difficulty of operation and potentially leading to inaccurate adjustments that affect writing quality.

[0005] Therefore, how to provide a pen tip and pen with adjustable ink flow that is simple in structure and easy to operate is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides an adjustable ink flow pen nib and a pen, aiming to fill the gap in directly finished products.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An adjustable ink flow fountain pen tip includes a sleeve and a pen tip body inserted into the sleeve, the pen tip body having an ink-drawing slit at the tip; and further includes:

[0009] An adjusting ring, which is threadedly connected to one end of the sleeve that is inserted into the pen tip body;

[0010] An arc-shaped plate has its concave surface fitted to the outer surface of the pen tip with the ink-drawing slit, and its two side edges engaging with the two side edges of the pen tip to prevent separation of the arc-shaped plate from the outer surface of the pen tip. The end edge of the arc-shaped plate abuts against the end face of the adjusting ring. By rotating the adjusting ring, the arc-shaped plate is propelled towards the tip of the pen tip, so that the two side edges of the arc-shaped plate can apply a squeezing force towards the central axis to the two side edges of the pen tip to adjust the width of the ink-drawing slit.

[0011] Through the above technical solution, this utility model discloses an adjustable ink flow pen tip. The sleeve serves as a support structure for the pen tip body, providing a stable mounting base for the pen tip body and a carrier for the threaded connection of the adjusting ring. By rotating the adjusting ring, the arc plate moves along the axial direction of the pen tip body, thereby changing the width of the ink slit and adjusting the ink flow. This eliminates the need for complex operating steps, reducing the difficulty of operation and solving the technical problem of needing to adjust multiple screws in the prior art, which increases the difficulty of operation. At the same time, the threaded connection design of the sleeve and the adjusting ring allows for more precise adjustment, and the tight fit between the arc plate and the pen tip body ensures the stability and reliability of the adjustment process.

[0012] Preferably, in the above-mentioned adjustable ink flow pen tip, both sides of the curved plate have protruding ribs extending inwards towards their concave surfaces, and the two ribs are respectively engaged with the two sides of the pen tip. The design of the ribs restricts the movement direction of the curved plate, allowing it to move smoothly along the axial direction of the pen tip body, avoiding inaccurate adjustment due to offset, thereby achieving more precise ink flow adjustment; the ribs also ensure that the curved plate does not wobble or shift during the adjustment process, improving the stability and reliability of the adjustment process.

[0013] Preferably, in the above-mentioned adjustable ink flow fountain pen tip, the pen tip body further includes a feed, on which a plurality of annular grooves are spaced apart, and an ink-guiding groove communicating with the plurality of annular grooves is axially formed on its side wall; the pen tip surrounds the outer surface of the feed on the side with the ink-guiding groove, and the ink-guiding groove corresponds to the ink-guiding groove. The plurality of annular grooves spaced apart on the feed and the ink-guiding grooves communicating with them form an ink temporary storage area, maintaining a continuous ink supply through capillary action; it can effectively guide the ink to flow evenly to the pen tip, making the ink flow more smoothly during writing and avoiding ink accumulation or ink interruption.

[0014] Preferably, in the above-mentioned adjustable ink flow fountain pen tip, the side of the feed away from the tip has a locking block, and the base of the tip has a locking groove that engages with the locking block. This locking structure achieves precise positioning and installation of the feed and tip, which is simple yet effective, preventing the tip from loosening or falling off during writing and ensuring stability during writing; at the same time, the detachable structure facilitates individual replacement of damaged parts.

[0015] Preferably, the above-mentioned adjustable ink flow pen tip also includes a pen grip, which is coaxially sleeved on the outside of the sleeve, and one end of which is inserted into the adjustment ring.

[0016] Preferably, in the above-mentioned adjustable ink flow pen tip, an annular slot is formed on the inner wall of the end of the adjusting ring away from the pen tip, and the pen grip is inserted into the annular slot. The insertion design of the pen grip and the adjusting ring provides dual positioning, ensuring that the pen grip does not rotate when the adjusting ring rotates; the annular slot provides axial freedom, avoiding torque transmission during adjustment.

[0017] Preferably, in the above-mentioned adjustable ink flow pen tip, the pen grip has an ink chamber communicating with the ink inlet end of the feed, and an ink filling channel communicating with the ink chamber. The independent ink filling channel enables non-destructive ink filling and is compatible with different ink filling methods.

[0018] This utility model also provides a fountain pen, including the above-mentioned adjustable ink flow nib.

[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a fountain pen nib and fountain pen with adjustable ink flow, which has the following beneficial effects:

[0020] 1. This utility model can change the width of the ink slit by rotating the adjustment ring, thereby adjusting the ink flow rate to meet different writing needs (such as drawing fine lines or writing bold characters), without complicated operation, thus reducing the difficulty of use.

[0021] 2. This utility model ensures that the squeezing force is evenly distributed by the convex strips on both sides of the arc plate and the pen tip, thus avoiding ink leakage or ink breakage caused by pen tip deformation and displacement.

[0022] 3. The snap-fit ​​structure between the pen feed and the pen tip, and the plug-in design between the pen grip and the sleeve of this utility model support individual component replacement, reducing maintenance costs. Attached Figure Description

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.

[0042] Example 1:

[0043] Participate in the attached Figure 1-4 This utility model discloses an adjustable ink flow pen tip, including a sleeve 1 and a pen tip body 2 inserted into the sleeve 1. The pen tip 21 of the pen tip body 2 has an ink-drawing slit 211; it also includes:

[0044] Adjusting ring 3 is threadedly connected to one end of sleeve 1 that is inserted into pen tip body 2;

[0045] The concave surface of the arc plate 4 is attached to the outer surface of the pen tip 21 with the ink-drawing slit 211, and the two side edges of the arc plate 4 are engaged with the two side edges of the pen tip 21, restricting the separation of the arc plate 4 from the outer surface of the pen tip 21. The end edge of the arc plate 4 abuts against the end face of the adjusting ring 3. By rotating the adjusting ring 3, the arc plate 4 is pushed towards the tip of the pen tip 21, so that the two side edges of the arc plate 4 can apply a squeezing force towards the central axis on the two side edges of the pen tip 21 to adjust the width of the ink-drawing slit 211.

[0046] To further optimize the above technical solutions, such as Figure 2As shown, both sides of the arc plate 4 have protruding strips 41 that protrude inward toward their concave surfaces, and the two protruding strips 41 are respectively engaged on the two sides of the pen tip 21.

[0047] To further optimize the above technical solutions, such as Figure 3 As shown, the pen tip body 2 also includes a nib 22, on which a plurality of annular grooves 221 are arranged at intervals, and an ink-drawing groove 222 communicating with the plurality of annular grooves 221 is axially opened on its side wall; the pen tip 21 surrounds the outer surface of the nib 22 on the side with the ink-drawing groove 222, and the ink-drawing slit 211 corresponds to the ink-drawing groove 222.

[0048] To further optimize the above technical solutions, such as Figure 4 As shown, the side of the pen feed 22 away from the tip of the pen tip 21 has a locking block 223, and the base of the pen tip 21 has a locking groove 212 that engages with the locking block 223.

[0049] To further optimize the above technical solution, a pen grip 5 is also included. The pen grip 5 is coaxially sleeved on the outside of the sleeve 1, and one end of it is inserted into the adjusting ring 3.

[0050] To further optimize the above technical solution, an annular slot is formed on the inner wall of the end of the adjusting ring 3 away from the pen tip 21, and the pen grip 5 is inserted into the annular slot.

[0051] To further optimize the above technical solution, the pen grip 5 has an ink chamber 51 that communicates with the ink inlet end of the pen feed 22, and an ink filling channel 52 that communicates with the ink chamber 51.

[0052] To further optimize the above technical solution, a silicone ring (not shown in the figure) is installed inside the ink injection channel 52.

[0053] This utility model also discloses a fountain pen, including the aforementioned adjustable ink flow fountain pen tip and a pen body. The pen body is the same as that of a conventional fountain pen in the prior art. It is used in conjunction with the adjustable ink flow fountain pen tip to meet different writing needs. The structure and working principle of the pen body are the same as those of the prior art, and will not be described in detail here.

[0054] Example 2:

[0055] See appendix Figure 5-14 This utility model embodiment discloses a fountain pen, including a pen grip 5, a pen barrel 6, a drive assembly 7, and the aforementioned fountain pen tip with adjustable ink flow;

[0056] The pen grip 5 is coaxially sleeved on the outside of the sleeve 1, and one end of it is inserted into the adjusting ring 3. The pen grip 5 has an ink chamber 51 that communicates with the ink inlet end of the pen tip body 2, and an ink filling channel 52 that communicates with the ink chamber 51.

[0057] One end of the pen barrel 6 is detachably connected to the end of the pen grip 5 away from the adjustment ring 3, and it has a receiving channel 61 inside. A spiral ink converter 8 is slidably connected coaxially inside the receiving channel 61. The ink filling end of the spiral ink converter 8 extends through the ink filling channel 52 into the ink chamber 51.

[0058] The drive assembly 7 is installed at the end of the pen barrel 6 away from the pen grip 5 and is connected to the spiral ink converter 8 for driving the spiral ink converter 8 to fill ink.

[0059] To further optimize the above technical solutions, such as Figure 6-8 As shown, the spiral ink converter 8 includes an ink reservoir 81 and a push rod 82. One end of the ink reservoir 81 is fixed with an ink-filling needle 83 that communicates with its interior. A piston 84 and a piston rod 85 are slidably connected inside the ink reservoir 81. One end of the push rod 82 is rotatably connected to the end of the ink reservoir 81 away from the ink-filling needle 83 and is threadedly connected to the piston rod 85. The other end of the push rod 82 has a first gear 86, which meshes with the drive assembly 7.

[0060] To further optimize the above technical solutions, such as Figure 9-10 As shown, the drive assembly 7 includes a cap 71 detachably connected to the pen barrel 6, and a rotating column 72 rotatably connected inside the cap 71. The outer side of the rotating column 72 is fitted with a second gear 73 that meshes with the first gear 86.

[0061] To further optimize the above technical solutions, such as Figure 8 As shown, an ink injection hole 831 is provided on the side wall of the ink needle 83.

[0062] To further optimize the above technical solutions, such as Figure 11-13 As shown, it also includes a locking component 9, which includes an L-shaped slot 91 and a locking pin 92 on the side wall of the pen grip 5. One end of the locking pin 92 is located on the outside of the pen grip 5, and the other end passes through the L-shaped slot 91 and is fixedly connected to the ink reservoir 81. Pushing the locking pin 92 along the L-shaped slot 91 causes the ink reservoir 81 to move axially along the pen barrel 6, so that the ink filling needle 83 retracts into the ink filling channel 52, thereby achieving a seal to stop ink.

[0063] To further optimize the above technical solutions, such as Figure 14 As shown, the inner wall of the receiving channel 61 is formed with a stepped surface 611, and a return spring 821 is sleeved on the outer side of the push rod 82. The return spring 821 is pressed between the stepped surface 611 and the end face of the ink storage cylinder 81.

[0064] To further optimize the above technical solution, the number of receiving channels 61, spiral ink converter 8, ink filling channel 52 and locking assembly 9 are all multiple and the number is the same; multiple receiving channels 61 are arranged circumferentially inside the pen barrel 6.

[0065] To further optimize the above technical solution, the pen barrel 6 has a double-layer cylindrical structure, with the receiving channel 61 located in the inner cylindrical layer.

[0066] To further optimize the above technical solution, a pen cap 10 is also included, which is placed on the outside of the pen tip body 2.

[0067] Therefore, the adjustable ink flow pen tip disclosed in this utility model can be used with components of ordinary pens or combined with the components in Embodiment 2 to form a brand-new multifunctional pen, which has a wide range of applicability.

[0068] The implementation method of Embodiment 1 of this utility model is as follows:

[0069] When it is necessary to adjust the width of the ink-drawing slit 211, simply rotate the adjusting ring 3 clockwise or counterclockwise to move the arc plate 4 along the axial direction of the pen tip 21. Through the protrusions 41 on both sides of the arc plate 4, a squeezing force is applied to both sides of the pen tip 21 in the direction of the central axis, thereby adjusting the width of the ink-drawing slit 211.

[0070] The implementation method of Embodiment 2 of this utility model is as follows:

[0071] When it is necessary to adjust the width of the ink slit 211, the operation process is the same as that in Example 1;

[0072] When ink needs to be drawn in, rotating the rotating column 72 drives the second gear 73 to rotate. Since the second gear 73 meshes with the first gear 86, the first gear 86 drives the push rod 82 to rotate, thereby causing the piston rod 85 to slide along the axial direction of the ink reservoir 81, thus drawing in ink. When ink needs to be added to the ink chamber 51, rotating the rotating column 72 in the opposite direction drives the second gear 83 to rotate, thereby causing the piston rod 85 to slide in the opposite direction along the axial direction of the ink reservoir 81, thus adding ink to the ink chamber 51. This embodiment also discloses a locking assembly 9. When the locking pin 92 is located at the top of the vertical groove of the L-shaped slot 91, the ink filling of the ink reservoir 81 is controlled. The needle 83 extends through the ink filling channel 52 into the ink chamber 51 to fill ink. When the locking pin 92 is pushed into the transverse groove of the L-shaped slot 91, the locking pin 92 drives the ink reservoir 81 to move away from the pen tip, causing the ink filling needle 83 to retract into the ink filling channel 52. At the same time, the ink filling channel 52 has a silicone ring, which seals the ink filling hole 831. Meanwhile, the first gear 86 and the second gear 73 no longer mesh. At this time, rotating the rotating column 72 will not fill ink, ensuring that the ink is stored in the ink reservoir 81 and will not flow into the ink chamber 51.

[0073] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0074] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
