Description

Technical Field

[0001] This utility model relates to the field of stationery, specifically to an adjustment component, a pressing mechanism, and a pen. Background Technology

[0002] In everyday writing scenarios such as office work and study, push-button pens are widely used because they do not require pen caps and are convenient to use. Traditional push-button pens typically use a fixed refill cavity and a push-to-drive mechanism. Their working principle is that pressing the component triggers an internal locking or linkage device to push the refill out of the pen tip for writing, and pressing again retracts the refill.

[0003] However, existing push-button pens have significant drawbacks. Because different manufacturers produce refills of varying lengths, and users often replace refills themselves when they run out, the new refill may not be the same length as the original. Furthermore, the push-button linkage mechanism in existing pens is often of a fixed length. When a shorter refill is installed, it may not be able to extend from the tip for writing; when a longer refill is installed, it may not retract completely, potentially causing bending or damage to the pen's internal structure. This severely limits the pens' applicability to different refills, reduces user experience, and diminishes product versatility.

[0004] Existing technologies include improved structures that can adapt to pen refills of different lengths, but most of them employ an adjustable telescopic structure within the pen barrel itself, such as CN200920026752 – Adjustable All-Purpose Ballpoint Pen. This solution combines a pen holder, outer sleeve, and inner sleeve, allowing the length of the entire pen barrel (100) to be adjusted to accommodate pen refills of different lengths. However, it cannot be adapted to push-button pens and leads to increased complexity and weight in the pen barrel structure. Utility Model Content

The linkage design between the adjusting structure and the first or second adjusting component allows the linkage seat to move closer to or further away from the first adjusting component. Based on this structure, when faced with pen refills of varying lengths from different manufacturers, or non-standard length refills replaced by the user, it ensures that the pen refill can be smoothly extended from the pen tip for writing and completely retracted into the pen body after use. This effectively avoids situations where the pen refill cannot be extended or retracted due to a mismatch between the pen refill length and the press-to-retract mechanism, or even results in the pen refill being bent or the internal structure of the pen being damaged. This greatly expands the compatibility of press-type pens with different pen refills, significantly improving the product's versatility and user experience. Attached Figure Description

[0066] 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.

[0067] Please see Figures 1-9This application provides the following technical solutions:

[0068] An adjustment assembly includes a first adjustment member 1 and a second adjustment member 2. The first adjustment member 1 has an external connecting portion A12 that can be connected to an external structure; the second adjustment member 2 has an internal connecting portion 22 that can be linked with an external component; an adjustment structure 3 is disposed between the first adjustment member 1 and the second adjustment member 2, and the adjustment structure 3 is linked with either the first adjustment member 1 or the second adjustment member 2. The internal connecting portion 22 of the second adjustment member 2 can move closer to or further away from the first adjustment member 1 through the adjustment structure 3.

[0069] Because this adjustment assembly is primarily used as an internal component of a push-button pen, the external structure connected to the first adjustment member 1 via the external connecting part A12 is the pen barrel 100, and the external component linked to the second adjustment member 2 via the internal connecting part 22 is the pen refill 200. However, this adjustment assembly is not limited to conventional writing pens; it can also be used in structures such as cosmetic pens, electric pens, and utility knives that have similar push-to-release and retract mechanisms. Therefore, the pen barrel 100 can also be a corresponding electric pen outer casing, utility knife shell, or similar structure, and the pen refill 200 can also be a corresponding core structure, i.e., the aforementioned external component. For ease of explanation, a push-button pen will be used as an example thereafter. The first adjustment member 1 and the second adjustment member 2 are coaxially arranged within the pen barrel 100, and the adjustment structure 3 is located at the end where the first adjustment member 1 and the second adjustment member 2 are close to each other.

[0070] With the structure of this solution, the first adjusting member 1 can be positioned on the pen barrel 100 via the outer connecting part A12, thereby achieving relative movement between the second adjusting member 2 and the first adjusting member 1. This relative movement causes the position of the inner connecting part 22 in the second adjusting member 2 to shift relative to the first adjusting member 1, thus changing the distance between them. (See also...) Figure 3The inner connecting part 22 adopts a conventional array-shaped guide structure of a push-button pen, which consists of several protruding strips. The end of each protruding strip facing the pen tip has a stepped structure and an inclined surface, and guide grooves are provided between adjacent protruding strips. This structure corresponds to the linkage seat 400 of an existing push-button pen. The pen refill 200 is inserted into one side of the linkage seat 400, and its periphery also has a strip-shaped structure corresponding to the protruding strips of the inner connecting part 22. When the pressing member 300 presses the linkage seat 400, the linkage seat 300 slides and rotates slightly relative to the inner connecting part 22, thereby realizing the ejection or retraction of the pen refill 200. The specific structural shapes of the linkage seat 400, inner connecting part 22, and pressing member 300 are existing technologies and will not be described in detail here. The main improvement of this solution is that the inner connecting part 22 is placed on the second adjusting member 2, and then the position of the second adjusting member 2 within the pen barrel 100 is changed by the adjusting structure 3, thereby indirectly changing the position of the linkage seat 400 within the pen barrel to accommodate pen refills 200 of different lengths. This improvement does not require any adjustment to the pen barrel 100; the pen barrel 100 can adopt a traditional integrated form or a separate connection form.

[0071] Based on the above implementation scheme, and considering the matching of the internal space of a conventional pen shape, both the first adjusting member 1 and the second adjusting member 2 are hollow cylindrical structures; the first adjusting member 1 and the second adjusting member 2 can be fitted with a linkage seat 400 and a pressing member 300.

[0072] The first adjusting member 1 and the second adjusting member 2 are not limited to a cylindrical structure; other internal cavity connection forms for irregularly shaped pen bodies are also possible. The first adjusting member 1 and the second adjusting member 2 only need to be able to connect internally to the pen barrel 100 and have adjustable mobility.

[0073] Based on the above implementation scheme, the first adjusting member 1 includes a first main body 11 that can be fitted into the pen barrel 100. The first main body 11 is a cylindrical body. An outer connecting part A12 is disposed on the outer wall of the first main body 11. The first main body 11 is connected to the inside of the pen barrel 100 through the outer connecting part A12. The second adjusting member 2 includes a second main body 21, which is also a cylindrical body. The second main body 21 has a cavity inside that can fit the pen refill 200 and the linkage seat 400. An inner connecting part 22 is disposed inside the second main body 21. An outer connecting part B23 is disposed on the outside of the second main body 21. The second main body 21 is connected to the pen barrel 100 through the outer connecting part B23.

[0074] Based on the above implementation scheme, the specific movement forms of the first adjusting member 1 and the second adjusting member 2 can be varied, as long as the positional relationship between them can change. The following structural form is adopted in this scheme.

[0075] The outer connecting part A12 is a rotatable connection structure, through which the first main body 11 is rotatably connected to the end of the pen barrel 100; the outer connecting part B23 is a sliding connection structure, through which the second main body 21 is slidably connected to the inside of the pen barrel 100, with the sliding direction being the axial direction of the pen barrel 100. Through this structure, the first adjusting member 1 can rotate relative to the pen barrel 100 without displacement in the axial direction. By rotating the first adjusting member 1, the second adjusting member 2 slides within the pen barrel 100, thereby changing the position of the linkage seat 400. How the adjusting structure specifically achieves the positional changes of the first adjusting member 1 and the second adjusting member 2 will be further explained later.

[0076] Based on the above implementation plan, see Figure 6 and Figure 7 The outer connecting part A12 includes a first connecting member 121 and a second connecting member 122. Both the first connecting member 121 and the second connecting member 122 are annular structures disposed around the first main body 11. The outer diameter of the first connecting member 121 is greater than or equal to the outer diameter of the end of the pen barrel 100; a gap is left between the second connecting member 122 and the first connecting member 121; the second connecting member 122 is greater than or equal to the inner diameter of the pen barrel 100. Considering the fit of the second connecting member 122, it is preferable to provide a matching fitting structure inside the pen barrel 100 corresponding to the second connecting member 122.

[0077] Various forms can be adopted for the specific shape of the annular structure. For example, in this solution, both the first connector 121 and the second connector 122 are outwardly convex annular boss structures. The first connector 121 can abut against the end of the pen barrel 100, and the pen barrel 100 can have an annular groove for fitting the second connector 122. This achieves a rotatable connection.

[0078] Unlike the above scheme, the end of the pen barrel 100 can also be provided with an annular groove to achieve a rotatable connection with the first connector 121 in a snap-fit ​​manner.

[0079] In addition, the first connector 121 and the second connector 122 can also adopt the structure of an annular groove. In this case, the pen barrel 100 can be provided with a boss structure that can be inserted into the groove.

[0080] As an adaptive adjustment to the above scheme, the first connector 121 and the second connector 122 can also adopt a structure in which one is a groove and the other is a boss, and the specific selection form is not limited.

[0081] The outer connecting part B23 of the second adjusting member 2 is an elongated guide groove or guide block provided on the outer side of the second main body 21. A matching sliding structure is provided inside the pen barrel 100 corresponding to the outer connecting part B23. The outer connecting part B23 shown in the attached drawings is a guide groove structure, with two guide grooves symmetrically formed on both sides of the outer wall of the second main body 21. Therefore, only a corresponding guide block needs to be provided inside the pen barrel 100. In this way, the second adjusting member 2 is limited to sliding axially within the pen barrel 100 and will not rotate.

[0082] Based on the above implementation scheme, the first adjusting member 1 further includes a first limiting member 13, which is disposed on the outer wall of the first main body 11. The first limiting member 13 can limit the rotation angle of the first adjusting member 1. In this scheme, the first limiting member 13 is a block-shaped boss structure, and a corresponding limiting boss can also be provided inside the pen barrel 100. As the first adjusting member 1 rotates, when the first limiting member 13 and the limiting boss inside the pen barrel 100 abut against each other, the first adjusting member 1 cannot continue to rotate. This is how the rotation range of the first adjusting member 1 is limited.

[0083] Based on the above implementation scheme, the first adjusting member 1 also includes a screwing structure 14. The screwing structure 14 is located on the outside of the first main body 11. It only needs to facilitate the rotation of the first adjusting member 1. The screwing structure 14 can be an anti-slip strip or anti-slip groove located on the periphery of the first main body 11. The anti-slip strip is shown in the attached figure of this scheme.

[0084] Based on the above implementation scheme, the adjustment structure 3 only needs to satisfy the requirement that the second adjustment component 2 can slide by rotating the first adjustment component 1. Various linkage methods can be adopted, and the following one is given in this scheme.

[0085] See Figures 3 to 9 The adjustment structure 3 includes an adjustment member A31 fixedly connected to the first main body 11, and an adjustment member B32 fixedly connected to the second main body 21. The adjustment member A31 includes two pushers, which in this design are rods protruding towards the inside of the first main body 11; two pushers are symmetrically arranged inside the first main body 11.

[0086] Adjusting member B32 is annular, and an adjusting groove group is provided on the edge of adjusting member A31. The adjusting groove group consists of several adjusting grooves of different depths; the opening end of the adjusting groove faces the first adjusting member 1, and its bottom is arc-shaped. The end of the pushing member can be inserted into the adjusting groove. Adjusting member B32 includes two adjusting groove groups.

[0087] The different depths of the adjustment grooves mentioned here refer to the distance from the bottom of the groove to the outermost edge of the adjustment component B32. Figure 3Taking the direction shown as an example, the outermost edge of the adjusting member B32 is the left edge. The adjusting member B32 is a ring structure, which is fitted inside the end of the first adjusting member 1. The adjusting grooves are distributed in an inclined manner, facing towards the attached... Figure 3 The depth gradually increases from the left side. The highest and lowest ends of adjacent regulating tank groups are connected to form a ring.

[0088] In actual production, there can be more pushers, as long as they are evenly distributed in a ring. Considering the difficulty of production and the stability of use, this solution is better in the form of a combination of two pushers and two adjustment slots.

[0089] Because the pusher of the adjusting member A31 is pressed against the adjusting groove, when the first adjusting member 1 rotates, the pusher switches between different adjusting grooves of the adjusting member B32, thereby causing the position of the second adjusting member 2 to change.

[0090] Based on the above implementation plan, see Figures 10 to 12 This solution also provides a pressing mechanism using the aforementioned adjusting components, including a pressing member 300 and a linkage seat 400. One end of the linkage seat 400 has a slot, and the linkage seat 400 is sleeved inside the second adjusting member 2, with the linkage seat 400 and the inner connecting portion 22 in sliding engagement. The pressing member 300 is sleeved inside the first adjusting member 1, with one end extending to the outside of the first adjusting member 1 and the other end extending into the second adjusting member 2, and the end of the second adjusting member 2 facing towards the linkage seat 400 abutting against it.

[0091] As mentioned earlier, the adjustment component of this solution is not only suitable for writing pens, but also adaptable to corresponding devices with press-type pop-out and retraction structures. Therefore, the pressing mechanism proposed in this solution utilizes the aforementioned adjustment component. Different components can be installed on the corresponding linkage base 400, including writing pen refills, cosmetic pen bodies, electric pen barrels, utility knife connecting rods, etc.

[0092] Based on the above implementation plan, see Figures 13 to 15This solution also provides a pen that uses the aforementioned adjustment components or mechanism. It includes a pen barrel 100, a refill 200, a pressing member 300, and a linkage seat 400. A first adjusting member 1 is rotatably disposed at the end of the pen barrel 100 away from the pen tip. A second adjusting member 2 is slidably connected inside the pen barrel 100. The connection form between the pen barrel 100 and the first and second adjusting members 1 and 2 can be referred to the previous description and will not be repeated here. The linkage seat 400 is inserted into the end of the refill 200 away from the pen tip, and the linkage seat 400 is sleeved inside the second adjusting member 2. The linkage seat 400 and the inner connecting part 22 are slidably engaged. This slidable engagement is the sliding and rotating of the linkage seat 400 mentioned above, i.e., the movement of a conventional pressing pen. The pressing member 300 is sleeved inside the first adjusting member 1, with one end extending to the outside of the first adjusting member 1 and the other end extending into the second adjusting member 2. The end of the second adjusting member 2 located inside the second adjusting member 2 abuts against the linkage seat 400. In addition, a spring is provided on the periphery of the pen refill 200 near the end of the pen barrel 100 to provide a restoring force to the pen refill 200 when it retracts.
