Description

Technical Field

[0001] This utility model relates to the field of stationery, specifically to a press-type pen transmission component, pen refill, linkage assembly, and pen. Background Technology

[0002] Retractable pens have long held a significant market position in writing instruments due to their convenient operation and compact design. Traditional retractable pens extend and retract the pen tip by pressing the end of the pen. Their core working principle revolves around a reciprocating motion component—when the user applies pressure, internal springs, latches, and other components work together to complete a cycle of force storage and release, thereby changing the working state of the pen tip.

[0003] However, with the development of multifunctional writing instruments, the single function of nib extension is no longer sufficient to meet diverse usage needs. Currently, the structural design of traditional push-button pens has significant limitations: it only includes components related to the reciprocating motion of the nib extension, lacking a structure capable of effectively transmitting the pressing action. This means that the energy of the pressing action can only act on the nib control of the pen itself, and cannot be extended to drive other functional modules. Utility Model Content

[0004] To address one of the shortcomings of existing technologies, this utility model provides a push-type pen transmission component, which solves the linkage problem of the pressing action of the push-type pen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a press-type pen transmission component, characterized in that it comprises:

[0006] The connecting structure is a cylindrical body that can be connected to the pen refill assembly;

[0007] The transmission structure is fixedly installed on the outer side of the cylindrical wall of the connecting structure. The transmission structure is a long strip-shaped block, and the length direction of the transmission structure is parallel to the axial direction of the connecting structure. One end of the transmission structure is a pushing part, which can be linked with external parts.

[0008] The limiting structure is a boss located on the outer side of the connecting structure cylinder wall; the limiting structure is located near the pushing part;

[0009] The reset structure is a boss located on the outer side of the connecting structure cylinder wall; the reset structure is located away from the pushing part.

[0011] Preferably, the end of the press-type pen actuator facing the pen tip in the use state is the front end;

[0012] The driving part of the transmission structure includes:

[0013] An insert is located at the front end of the pusher, and the front end of the insert is a pointed tip; the rear ends of the insert have stepped structures on both sides.

[0014] Preferably, the front edge of the limiting structure is located at the tip of the insert, and the rear edge of the limiting structure is located at the stepped structure of the insert.

[0015] A pen refill that uses a press-type pen action mechanism as described above.

[0016] Preferably, it includes:

[0017] The regulator is located inside the connection structure;

[0018] The pen tip limiting component is inserted into the front end of the connecting structure, and a through hole is provided in the middle of the pen tip limiting component;

[0019] The pen tip is inserted into the pen tip limiting member, and the pen tip can pass through the pen tip limiting member and be connected to the adjuster;

[0020] The ink cartridge connector is plugged into the rear end of the connection structure.

[0021] Preferably, it also includes:

[0022] A sealing ring is fitted into an annular groove at the rear end of the connecting structure.

[0023] A linkage component, using the pen refill as described above, further includes:

[0024] A linkage component is disposed on the front side of the connecting structure. The linkage component is a cylindrical body and is sleeved and slidably connected to the connecting structure. The transmission structure abuts against the linkage component.

[0025] Preferably, the linkage component includes:

[0026] The linkage groove is a through groove formed on the cylinder wall of the linkage component. One end of the linkage groove is an open end, and the transmission structure can be inserted into the linkage groove through the open end of the linkage groove.

[0027] A linkage block is disposed inside the linkage groove. Two linkage blocks are symmetrically arranged and are located on two opposite groove walls of the linkage groove. When the transmission structure is inserted into the linkage groove, the linkage blocks are located on both sides of the transmission structure. The front side of the linkage block is an inclined surface, and the rear side is a plane corresponding to the stepped structure of the insert.

[0028] A positioning structure is provided inside the linkage component. The positioning structure is an annular boss near the rear end of the linkage component, and the positioning structure is located behind the limiting structure of the press-type pen transmission component.

It is highly compatible with pen refill components, has no technical difficulties in production and processing, and is easy to popularize and promote. Attached Figure Description

[0045] 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.

[0046] Please see Figures 1-3 This application provides the following technical solutions:

[0047] A push-button pen actuator includes a cylindrical connecting structure 11, which can be connected to a pen refill assembly. A transmission structure 12, a limiting structure 13, and a resetting structure 14 are fixedly disposed on the outer side of the cylindrical wall of the connecting structure 11. The transmission structure 12 is an elongated block, with its length parallel to the axial direction of the connecting structure 11. One end of the transmission structure 12 is a pushing part 121, which can be linked with external parts. The limiting structure 13 and the resetting structure 14 are both annular bosses disposed on the outer side of the cylindrical wall of the connecting structure 11. The limiting structure 13 is disposed close to the pushing part 121, and the resetting structure 14 is disposed away from the pushing part 121.

[0048] The connecting structure 11 can be sleeved on the outer wall of the pen refill, or it can be used directly as the outer wall of the pen refill. If it is sleeved on the outer wall of the pen refill, it can be made by interference fit, snap-fit, plug-in, etc. The specific connection method is not the focus of this solution and will not be described in detail here.

[0049] The limiting structure 13 and the reset structure 14 are designed to limit the external structure when linked with the external structure, as well as reset the transmission component itself. For example, the reset structure 14 can be combined with the external structure to set a reset spring between the two.

[0050] Based on the above implementation plan, see Figure 3For ease of explanation, the end of the press-type pen actuator facing the pen tip in its active state is considered the front end. The transmission structure 12 is an overall elongated right-angled trapezoidal body, with its right-angled surface being part of the pushing part 121, extending forward, and its inclined surface is located at the rear. The pushing part 121 also includes an insert 1211, which is an isosceles triangle located at the very front end of the transmission structure 12, that is, on the right-angled surface of the right-angled trapezoidal body. The apex of the insert 1211 faces forward, and the rear end face, that is, the bottom face, of the insert 1211 has stepped structures on both sides. The front edge of the limiting structure 13 is located at the tip of the insert 1211, and the rear edge of the limiting structure 13 is located at the stepped structure of the insert 1211.

[0051] The tip of the insert 1211 can be used for positioning during transmission, while the stepped structure at the rear can be used as a force-applying structure. Combining these two functional structures, the pressing action can be effectively transmitted. The limiting structure 13, in this configuration, can work with the insert 1211 to position the external linkage component.

[0052] See Figure 4 and Figure 5 This solution also provides a pen refill, which is the aforementioned form using a press-type pen actuator 1 as the outer wall of the pen refill. The pen refill of this solution also includes an adjuster 2, a tip limiter 3, a pen tip 4, an ink cartridge connector 5, and a sealing ring 6. The adjuster 2 is located inside the connecting structure 11. An existing fountain pen adjuster can be used for the adjuster 2, and its structure will not be described in detail here. The tip limiter 3 is inserted into the front end of the connecting structure 11, and a through hole is provided in the middle of the tip limiter 3. The pen tip 4 is inserted into the tip limiter 3, and the pen tip 4 can pass through the tip limiter 3 and connect to the adjuster 2. Because the connector 11 is used directly as the outer wall of the pen refill, it is necessary to ensure that there is no ink leakage. Therefore, the tip limiter 3 is provided, allowing it to be directly connected to the front end of the connecting structure 11, and simultaneously serving as a connection and limit structure for the pen tip 4. The tip limiter 3 and the pen tip 4 can also be implemented using existing technologies, and their detailed structures will not be described in detail here. An ink cartridge connector 5 is provided at the rear end of the connecting structure 11. An ink cartridge is inserted through the ink cartridge connector 5 for use as a refillable fountain pen. A sealing ring 6 is fitted into the annular groove provided at the rear end of the connecting structure 11. The sealing ring 6 must be able to fit against the inner side of the pen barrel. The sealing ring 6 separates the interior of the pen barrel into a chamber for the ink cartridge, minimizing the risk of ink leakage and contamination of the pen refill structure.

[0053] See Figures 6 to 8This solution also provides a linkage component, which uses the pen refill as described above. A linkage member 7 is provided on the outer front end of the pen refill. The linkage member 7 is a cylindrical body and is sleeved and slidably connected to the connecting structure 11.

[0054] The linkage component 7 has an elongated linkage groove 71 on its cylindrical wall. The rear end of the linkage groove 71 is open, allowing the transmission structure 12 to be inserted into the linkage groove 71 through the open end. See also Figure 8 Inside the linkage groove 71, there are two symmetrically arranged linkage blocks 72, located on two opposite groove walls of the linkage groove 71. When the transmission structure 12 is inserted into the linkage groove 71, the linkage blocks 72 are located on both sides of the transmission structure 12. The front side of the linkage block 72 is an inclined surface, and the rear side is a plane corresponding to the stepped structure of the insert 1211. It should be noted that the corners of the planes of the stepped structures corresponding to the linkage block 72 and the insert 1211 are rounded. Inside the linkage member 7, there is a positioning structure, which is an annular boss near the rear end of the linkage member 7, and the positioning structure is located behind the limiting structure 13 of the press-type pen transmission member 1.

[0055] For ease of explanation, we will use the extended state of the pen tip as state one and the retracted state of the pen tip as state two. Figure 8 The diagram shows state one, where the insert 1211 extends between the two linkage blocks 72, and the stepped structure at the rear of the insert 1211 abuts against the planar side of the linkage block 72. With the applied pressure, the pen refill moves forward, and the transmission structure 12 drives the linkage 7 to move synchronously. Considering that the travel distance of this linkage component during use is mostly different from the pressing distance, a linkage groove 71 is provided. When the linkage 7 reaches its corresponding travel position, it cannot move further. At this point, the pushing part 121 continues to move forward, slightly compressing the cylindrical walls on both sides of the linkage groove 71 to deform and open it, allowing the transmission structure 12 to enter the linkage groove 71. The difference between the pressing distance and the movement of the linkage 7 does not cause structural interference.

[0056] When in the second steering state, the transmission structure 12 moves rearward. Because the linkage block 72 is clamped on both sides of the transmission mechanism 12, the transmission structure 12 drives the linkage 7 to move backward synchronously. With the cooperation of the limiting structure 13 and the positioning structure of the linkage 7, it is ensured that the linkage 7 and the press-type pen transmission component 1 will not disengage.

[0057] The linkage component of this solution can be applied to relevant pen structures that require the linear motion of linkage component 7 as the driving force. The specific application can be selected according to the actual situation, and will not be elaborated here.
