Description

Technical Field

[0001] This utility model relates to the field of stationery, specifically to a push-button pen tip assembly and a push-button pen. Background Technology

[0002] As a convenient writing tool, the push-button pen is widely used in many scenarios such as daily writing, office note-taking, and student learning because it can extend and retract the pen tip without unscrewing the cap and simply by pressing the button.

[0003] In existing push-button pens, the pen head is divided into sections to ensure the pen tip can smoothly enter and exit for writing and storage, requiring a through hole at the pen head for the pen tip to pass through. However, the presence of this through hole makes this push-button structure unsuitable for fountain pens (such as ballpoint pens that rely on liquid ink).

[0004] For fountain pens, the perforation at the nib directly exposes the ink to continuous airflow, making it highly susceptible to evaporation and drying. This not only significantly shortens the ink's lifespan but also severely impacts writing smoothness due to changes in ink concentration, and may even cause nib clogging, rendering the pen unusable. For this reason, traditional fountain pens often require a cap to seal the nib and prevent these problems, which greatly limits the application of push-button mechanisms in the fountain pen industry.

[0005] At the same time, even for other types of push-button pens, when the pen is not in use and the tip is retracted into the pen head, the open hole can still cause a series of problems: external dust and impurities can easily enter the pen head through the hole, contaminating the tip or the internal channels of the pen and affecting the writing quality; during carrying, if other items accidentally come into contact with the open hole, they may also cause accidental damage to the retracted tip, affecting the normal use of the pen. Utility Model Content

[0006] To address one of the shortcomings of existing technologies, this utility model provides a push-button pen tip assembly and a push-button pen, solving the problem of the closed position of the pen tip in push-button pens.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a push-button pen tip assembly, comprising:

[0008] The shell has an internal cavity. A pen tip through hole is provided on the cavity wall at one end of the cavity so that the pen tip can pass through. A pen tip connecting part is provided at the end of the shell away from the pen tip through hole. The shell can be connected to the external pen barrel structure through the pen tip connecting part.

[0010] The shielding part has an area larger than the area of ​​the pen tip through hole, and the shielding part can block the pen tip through hole;

[0011] A cover connecting part is provided on the side of the shielding part, and the shielding part is rotatably connected to the housing through the cover connecting part.

[0012] Preferably, the pen tip through hole of the housing is a non-circular hole;

[0022] Preferably, the cover is disposed inside the housing;

[0023] The housing also includes:

[0024] A sealing ring is provided on the inner side of the housing and surrounds the pen tip through hole;

[0025] When the cover is in a closed state over the pen tip through hole, the outer side of the shielding part is in contact with the sealing ring.

[0026] Preferably, the cover is disposed inside the housing;

[0027] The first rotating structure is a notch provided on the inner wall of the housing;

[0028] The second rotating structure is a shaft corresponding to the notch of the first rotating structure.

[0029] Preferably, it also includes:

[0037] Compared with existing technologies, it has the following beneficial effects:

[0038] With this design, when the pen tip retracts into the casing, the shielding part of the cover completely blocks the tip's opening, preventing ink from continuously contacting the outside air and significantly reducing ink evaporation and drying. This not only extends the ink's lifespan but also maintains stable ink concentration, ensuring smooth writing and effectively preventing the pen tip from clogging due to dried ink. It overcomes the limitations of push-button designs in fountain pens, allowing them to offer the convenience of push-button operation.

[0039] Meanwhile, for other types of push-button pens, when not in use, the shielding part seals the pen tip opening, preventing external dust and impurities from entering the pen tip through the opening, thus avoiding contamination of the pen tip or internal channels and ensuring writing quality. In addition, the sealed opening also protects the retracted pen tip during carrying, preventing other items from accidentally contacting and damaging the pen tip, extending the pen's lifespan, and improving product reliability and user experience.

[0040] Furthermore, the cover is designed to rotate and connect with the housing through the cover connecting part. Combined with the linkage, the cover can open or close the pen tip hole in conjunction with the pressing action of the pen during use. Without any additional complicated operation steps, the hole can be automatically closed in conjunction with the extension and retraction action of the pen tip of the push-button pen. While ensuring the sealing effect, it does not affect the original convenience of the push-button pen. Attached Figure Description

[0053] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] Please see Figures 1-8 This application provides the following technical solutions:

[0055] A push-button pen tip assembly includes a housing 1 and a cover 2. The housing 1 has an internal cavity, with a pen tip through-hole 11 on one end of the cavity wall for the pen tip to pass through. A pen tip connecting part 12 is located at the end of the housing 1 away from the pen tip through-hole 11. The housing 1 can be connected to an external pen shaft structure via the pen tip connecting part 12. The pen tip connecting part 12 can be of various forms, such as snap-fit ​​or plug-in; this design uses a threaded connection. The housing 1 adopts a combined structure of a near-hemispherical shell and a cylindrical shell. The pen tip through-hole 11 is located at the central axis of the near-hemispherical shell structure, through which the pen tip passes. For ease of explanation, the direction in which the pen tip passes through will be considered forward. The pen tip connecting part 12 is located on the cylindrical shell and is designed with an internal thread. The cover 2 is connected to the housing 1, and the cover 2 includes a shielding part 21 and a cover connecting part 22. The area of ​​the shielding part 21 is larger than the area of ​​the pen tip through hole 11, and the shielding part 21 only needs to be able to block the pen tip through hole 11. The cover connecting part 22 is provided on the side of the shielding part 21, and the shielding part 21 is rotatably connected to the housing 1 through the cover connecting part 22.

[0056] There are several ways to set up the cover 2. In terms of the number of covers 2, they typically include single and double covers. A single cover 2 involves rotating one cover 2 on the housing 1, which, through its rotation, either closes the pen tip through-hole 11 or avoids it. A double cover 2 structure consists of two covers symmetrically arranged on the housing 1. When the two covers 2 rotate, they move closer or further apart, thus closing or opening the pen tip through-hole 11. However, considering that this design uses a pen with a relatively small structure, a single cover 2 structure is used. The axis of rotation of the cover 2 is perpendicular to the direction of pen tip extension and retraction. Furthermore, the cover 2 can be positioned either inside or outside the housing 1. In this design, considering both aesthetics and writing comfort, the cover 2 is placed inside the housing 1.

[0057] For the drive of the cover 2, you can choose manual or other drive methods, as long as it can drive the cover 2 to rotate.

[0058] Based on the above implementation scheme, the pen tip through hole 11 of the housing 1 is a non-circular hole; the hole wall of the pen tip through hole 11 includes a first arc surface and a second arc surface, and the two ends of the first arc surface and the second arc surface are connected to each other.

[0059] The nib through-hole 11 in this design is approximately semi-circular in shape. However, unlike a semi-circular hole, the first arc surface of the nib through-hole 11 is a larger arc than a semi-circle, and the second arc surface is not flat but rather an overall arc structure that is relatively close to a plane. This structure is chosen primarily because of the unique structural characteristics of fountain pen nibs, especially ballpoint pens. This shape of the nib through-hole 11 allows for better adaptation to the pen nib. Furthermore, this structure provides better support for the pen nib when it moves to its foremost position as it enters and exits the nib through-hole 11. Of course, a conventional round hole could also be used for the nib through-hole 11 in this design.

[0060] Based on the above implementation scheme, the shielding part 21 of the cover 2 is symmetrically provided with cover connecting parts 22 on both sides, and the cover connecting parts 22 are provided with a second rotating structure 221; the shell wall of the shell 1 is provided with a first rotating structure 13 corresponding to the cover connecting parts 22; the cover connecting parts 22 are rotatably connected to the shell 1 through the second rotating structure 221 and the first rotating structure 13.

[0061] In this design, the shielding part 21 and the cover connecting part 22 adopt an overall "U" shaped structure. The second rotating structure 221 and the first rotating structure 13 can be correspondingly arranged, and their specific forms are not limited. For example, in this design, the second rotating structure 221 is a cylindrical block used as a shaft, while the first rotating structure 13 can be a corresponding cylindrical or arc-shaped groove, or it can be a hole or other structure. This connection form can be used whether the cover 2 is located on the outside or inside the shell 1, only by changing the setting position and direction of the second rotating structure 221 and the first rotating structure 13.

[0062] Based on the above implementation plan, see Figure 4 and Figure 5 The shielding part 21 includes a shielding plate 211 with an arc-shaped plate structure. The two ends of the shielding plate 211 are connected to the cover connecting part 22. The middle part of the shielding plate 211 can block the pen tip through hole 11. The shielding plate 211 is arc-shaped as a whole, and its edges are also arc-shaped.

[0063] A shielding guide 212 is provided on the side of the shielding plate 211 facing the interior of the housing 1, which is the concave surface of the shielding plate 211, or the arc-shaped inner surface. Here, the concave surface and the arc-shaped inner surface of the shielding plate 211 are the same surface. Figure 5As shown, the shielding guide 212 is a block protruding towards the interior of the housing 1, and is disposed in the middle of the shielding plate 211. An inclined guide surface is provided on one side of the shielding guide 212 facing the interior of the housing 1. One side of the guide surface extends towards the concave side of the shielding plate 211, and the other side extends towards the convex side of the shielding plate 211. In other words, one side of the shielding guide 212 is thinner, and the other side is thicker. For ease of explanation, the side of the shielding guide 212 facing the convex side of the shielding plate 211 is designated as side A; the direction in which the shielding plate 211 rotates when closing the pen tip through hole 11 is designated as direction A; side A of the shielding guide 212 extends to the edge of the shielding plate 211 facing direction A. In other words, the thinner side of the shielding guide 212 is located at the edge of the shielding plate 211, while the thicker side is located in the middle of the concave surface of the shielding plate 211. It should be noted that the edge of the shielding plate 211 corresponding to the thinner side of the shielding guide 212 is the edge that rotates towards when the pen tip through hole 11 is closed.

[0064] The advantage of using the shielding guide 212 is that when the cover 2 is in a closed state to the pen tip through hole 11 until the cover 2 is about to be rotated open, the pen tip moves forward and will assist in pushing the shielding guide 212 from the inside of the housing. With the help of its inclined surface structure, the force is transmitted to the shielding plate 211, making it easier to rotate open.

[0065] Based on the above implementation scheme, a shielding reinforcement 213 is provided on one side of the shielding plate 211. The shielding reinforcement 213 is a reinforcing rib provided along the shielding plate 211. Because this scheme adopts a structure in which the cover 2 is located inside the shell 1, the shielding reinforcement 213 is located on the concave surface of the shielding plate 211.

[0066] Based on the above implementation scheme, the housing 1 also includes a sealing ring 14 on the inner side of the housing 1, and the sealing ring 14 surrounds the pen tip through hole 11; the sealing ring 14 is made of elastic material. When the cover 2 is in a closed state of the pen tip through hole 11, the outer side of the shielding part 21 is in contact with the sealing ring 14.

[0067] This structure enhances the sealing effect at the pen tip.

[0068] Based on the above implementation scheme, as mentioned earlier, the second rotating structure 221 of this scheme is a cylindrical block structure, which serves as the rotating shaft. See [link to relevant documentation]. Figure 3 The first rotating structure 13 is a circular notch corresponding to the second rotating structure 221. The notch is approximately "U" shaped and has a boss on one side of the open end of the notch. The side of the boss away from the notch is an inclined surface.

[0069] This design achieves a rotatable connection between the cover 2 and the shell 1 through this structure, while the protrusion on the outside of the notch is for convenient positioning during assembly.

[0070] Based on the above implementation scheme, this scheme includes a linkage component 3 as the driving structure for the cover 2. The linkage component 3 only needs to be able to be linked with the pressing component of the press-type pen; in other words, when the press-type pen is pressed, the linkage component 3 needs to be able to move together with the movement of the pen tip.

[0071] The cover 2 also includes a cover linkage part 23, which is linked with the linkage member 3. When the pen is pressed out, the linkage member 3 moves toward the housing 1, and the linkage member 3 drives the cover 2 to rotate toward the side that avoids the pen tip through hole 11. Conversely, when the pen is retracted, the linkage member 3 moves away from the housing 1, and drives the cover 2 to rotate toward the side that closes the pen tip through hole 11.

[0072] By introducing the linkage component 3, the cover 2 and the pen's pressing action are linked. There is no need to operate the cover 2 separately; simply pressing the pen normally will cause the cover 2 to rotate, opening or closing the pen tip through-hole 11. Various linkage methods can be used between the linkage component 3 and the pressing assembly, as long as the linkage component 3 can move together with the pen refill; the specific form is not limited.

[0073] Based on the above implementation scheme, this scheme provides the specific structural form of the cover linkage part 23, see [link / reference]. Figure 4 , Figures 6 to 8 The cover linkage part 23 is symmetrically arranged on both sides of the shielding part 21, and is located on the side of the second rotating structure 221 away from the shielding plate 211. The cover linkage part 23 has a hook-shaped structure, and its overall shape is approximately "7". The end of the linkage member 3 facing the cover 2 is provided with a hook-shaped active linkage part 31 corresponding to the cover linkage part 23. The active linkage part 31 is approximately "L"-shaped. The linkage action is achieved through the cooperation of the active linkage part 31 and the cover linkage part 23. Figure 7 As shown, the linkage 3 is currently positioned relatively far from the housing 1. The active linkage 31 drives the cover linkage 23, causing the cover 2 to rotate and close the pen tip through hole 11. See also Figure 8 In this configuration, the linkage 3 is located relatively close to the housing 1. The active linkage 31 pushes the cover linkage 23, causing the cover 2 to rotate to a position that avoids the pen tip through hole 11. The pen tip through hole 11 is then open, allowing the pen tip to extend.
