Description

Technical Field

[0001] This utility model relates to a writing instrument, and more particularly to a push-button pen. Background Technology

[0002] Pens are common stationery items in daily life. Based on their usage, pens are divided into push-button pens and retractable cap pens, among others. Push-button pens use a pressing mechanism to extend and retract the pen tip, making them more convenient for users and thus widely used. However, in conventional push-button pens, after the pen tip extends from the opening at the end of the pen barrel, a gap forms between the tip and the opening. This causes the pen tip to wobble relative to the pen barrel during writing, affecting the user's writing experience. Therefore, how to design a technology to reduce pen tip wobble and improve the user's writing experience is the technical problem this utility model aims to solve. Utility Model Content

[0051] like Figures 1-8 As shown, this utility model provides a press-type pen, comprising:

[0052] Pen barrel 1, one end of which forms an opening 11, and the inner wall of the pen barrel 1 is provided with a first anti-shake mating part 13, which is close to the opening 11;

[0053] The pressing component 2 includes a sliding tooth 21 and a rotating tooth 22, which are arranged opposite to each other. The sliding tooth 21 is slidably disposed in the pen barrel 1, and the rotating tooth 22 is rotatably disposed in the pen barrel 1 and can slide with the sliding tooth 21.

[0054] Pen refill 3, which is disposed in the pen barrel 1 and configured to slide in the pen barrel 1 following the rotating teeth 22;

[0055] Anti-sway component 4, which can slide and rotate with the rotating tooth 22, and is provided with a second anti-sway mating part 41;

[0056] The second anti-shake engagement part 41 is configured to selectively contact the first anti-shake engagement part 13 to prevent the pen tip 31 of the pen refill 3 from wobbling in the opening 11.

[0057] Specifically, the pen refill 3 is disposed in the pen barrel 1, and the pen tip 31 of the pen refill 3 can extend to the outside of the pen barrel 1 through the opening 11 of the pen barrel 1 to meet the writing requirements.

[0058] The sliding tooth 21 and rotating tooth 22 in the pressing component 2 can adopt the pressing structure of a conventional pressing pen. The rotating tooth 22 can slide along with the sliding tooth 21. In addition, the pen barrel 1 is generally provided with a positioning rib 14 to guide the rotating tooth 22 to slide and cooperate with the positioning rotating tooth 22. When the user presses once and releases, the pen tip 31 of the pen refill 3 extends to the outside of the pen barrel 1, and the rotating tooth 22 cooperates with the positioning rib 14 to maintain the writing state. When the user presses again and releases, the rotating tooth 22 slides along the positioning rib 14, so that the pen tip 31 of the pen refill 3 can retract into the pen barrel 1. Regarding the cooperation structure between the sliding tooth 21 and the rotating tooth 22 and the pen barrel 1, the structural configuration in conventional technology can be referred to, such as the pressing structure disclosed in Chinese Patent Publication Nos. CN207015018U, CN219055822U, and CN110126510B, which will not be limited or elaborated here.

[0059] With the pen tip 31 of the pen refill 3 retracted into the pen barrel 1, by applying pressure to the sliding tooth 21 in the pressing assembly 2, the sliding tooth 21 will drive the rotating tooth 22 to slide in the pen barrel 1. During the process of the pen tip 31 of the pen refill 3 moving out of the opening 11, the first anti-shake mating part 13 is not on the moving path of the second anti-shake mating part 41, thereby enabling the pen refill 3 and the anti-shake component 4 to slide smoothly relative to the pen barrel 1.

[0060] When the sliding tooth 21 slides to its maximum stroke, the rotating tooth 22 will disengage from the positioning rib 14 in the pen barrel 1. Under the action of the tooth surface of the rotating tooth 22 engaging with the tooth surface of the sliding tooth 21, the rotating tooth 22 will rotate. At this time, the second anti-wobbling engagement part 41 will rotate. During the retraction of the pen refill 3, since the first anti-wobbling engagement part 13 is on the moving path of the second anti-wobbling engagement part 41, the second anti-wobbling engagement part 41 will abut against the first anti-wobbling engagement part 13. This effectively clamps and fixes the pen tip 31 of the pen refill 3 in the opening 11 by the anti-wobbling component 4, preventing it from wobbling. Thus, during writing, the pen tip 31 is effectively confined in the opening 11 by the anti-wobbling component 4, preventing it from wobbling and improving the writing experience.

[0061] In one embodiment, in order to achieve automatic retraction of the pen tip 3, the press-type pen also includes a spring 5, which is disposed in the pen barrel 1 and configured to directly or indirectly apply a spring force to the pen tip 3 in a direction away from the opening 11.

[0062] Specifically, the spring 5, located within the pen barrel 1, applies a spring force to the pen tip 3 in a direction away from the hole 11. Thus, when the user presses the actuating component 2, they must overcome the spring force of 5, causing 5 to compress. When the user releases their grip, the pen tip 3 slides in the opposite direction under the action of the spring 5.

[0063] In one embodiment, the pen barrel 1 is provided with a pressing part 12, which can slide relative to the pen barrel 1. The pressing part 12 is disposed on the sliding teeth 21 to facilitate the user to apply pressure to the pressing part 12 to achieve the pressing operation. The physical manifestation of the pressing part 12 can be a pen cap disposed on the sliding teeth 21; or, the physical manifestation of the pressing part 12 can be a pen clip disposed on the sliding teeth 21. No limitation is placed on the specific physical manifestation of the pressing part 12.

[0064] In one embodiment of this application, the anti-shake component 4 is disposed on the outside of the pen refill 3;

[0065] After the second anti-sway mating part 41 and the first anti-sway mating part 13 are brought into contact, the pen tip 31 of the pen refill 3 is clamped in the anti-sway component 4.

[0066] Specifically, the function of the anti-shake component 4 is that when the pen tip 31 of the pen refill 3 is in the writing state, the anti-shake component 4 is attached to the first anti-shake component 13 through the second anti-shake mating part 41 to limit the shaking of the anti-shake component 4, thereby using the anti-shake component 4 to protect the pen tip 31 from shaking.

[0067] In one embodiment of this application, the anti-shake component 4 is provided with at least two extended clamping portions 42, which extend along the length direction of the anti-shake component 4 and are clamped on the pen tip 31 of the pen refill 3.

[0068] The second anti-sway mating part 41 is provided on the outer surface of the extended clamping part 42.

[0069] Specifically, the anti-shake component 4 has an extended clamping portion 42 near the end of the pen tip 31, with a notch structure formed between two adjacent extended clamping portions 42, and a second anti-shake mating portion 41 is provided on the extended clamping portion 42. During use, when the second anti-shake mating portion 41 is pressed tightly against the first anti-shake mating portion 13, the first anti-shake mating portion 13 will exert a squeezing force on the second anti-shake mating portion 41, thereby making the extended clamping portion 42 press more firmly on the pen tip 31, ensuring that the pen tip 31 is clamped and limited without shaking.

[0070] The anti-shake component 4 can be supported by a deformable material such as plastic, which allows the extended clamping part 42 to undergo a certain amount of elastic deformation. In this way, when the first anti-shake mating part 13 exerts pressure on the second anti-shake mating part 41, the pen tip 31 can be clamped more tightly by the extended clamping part 42.

[0071] After the second anti-sway mating part 41 and the first anti-sway mating part 13 are brought together, the extended clamping part 42 is pressed against the pen tip 31 of the pen refill 3, and the pen tip 31 of the pen refill 3 is clamped between the multiple extended clamping parts 42.

[0072] In one embodiment of this application, the first anti-shake mating part 13 is a protrusion structure formed on the inner wall of the pen barrel 1, and the second anti-shake mating part 41 is a protrusion structure formed on the outer wall of the anti-shake component 4.

[0073] Specifically, the first anti-wobbling fitting part 13 protrudes from the inner wall of the pen barrel 1, and correspondingly, the second anti-wobbling fitting part 41 protrudes from the outer wall of the anti-wobbling component 4. When the first anti-wobbling fitting part 13 comes into contact with the second anti-wobbling fitting part 41, the first anti-wobbling fitting part 13 generates an effective squeezing force on the second anti-wobbling fitting part 41 to ensure that the pen tip 31 does not wobble when writing.

[0074] In one embodiment of this application, the first anti-sway mating part 13 has a first inclined surface 131 formed at the end near the opening 11;

[0075] The second anti-shake mating part 41 has a second inclined surface 411 formed at the end of the pen tip 31 away from the pen refill 3;

[0076] After the second anti-sway mating part 41 and the first anti-sway mating part 13 are brought together, the first inclined surface 131 and the second inclined surface 411 are brought together.

[0077] Specifically, in order to ensure that the first anti-sway mating part 13 and the second anti-sway mating part 41 fit tightly together to improve the anti-sway protection capability, a first inclined surface 131 is formed on the first anti-sway mating part 13, and correspondingly, a second inclined surface 411 is formed on the second anti-sway mating part 41.

[0078] In this way, as the pen tip 31 extends from the pen barrel 1 and retracts to the writing position, the first inclined surface 131 and the second inclined surface 411 cooperate to gradually bring the first anti-wobbling engagement part 13 and the second anti-wobbling engagement part 41 together and tightly abut against each other. Furthermore, when the user presses the push-button assembly 2 again, the first anti-wobbling engagement part 13 and the second anti-wobbling engagement part 41 can also smoothly separate, improving the convenience and smoothness of use.

[0079] In one embodiment of this application, the anti-shake component 4 is a sleeve, and a second anti-shake mating part 41 is provided at one end of the sleeve; the sleeve is fitted over the outside of the pen refill 3, and the pen tip 31 of the pen refill 3 extends out of the sleeve.

[0080] Specifically, the anti-shake component 4 adopts a sleeve, with an extended clamping part 42 formed at one end of the sleeve. During assembly, the pen refill 3 is inserted into the sleeve, and the pen tip 31 is clamped between multiple extended clamping parts 42.

[0081] Furthermore, a first connecting part 43 is provided at the other end of the sleeve, and a first connecting mating part 221 is provided on the rotating tooth 22;

[0082] The first connecting part 43 and the first connecting mating part 221 are assembled together.

[0083] Specifically, the first connecting part 43 is positioned away from the extended clamping part 42. During the assembly process, after the pen refill 3 is inserted into the sleeve, the sleeve is connected to the first connecting engagement part 221 of the rotating tooth 22 through the first connecting part 43, thereby causing the rotating tooth 22 to rotate synchronously while driving the sleeve to rotate.

[0084] The physical manifestations of the first connecting portion 43 and the first connecting mating portion 221 can have various structural forms. For example, the first connecting portion 43 can be a tongue extending out of the sleeve, and the first connecting mating portion 221 can be a slot formed on the rotating tooth 22, with the tongue inserted into the slot; or, the first connecting portion 43 can be a claw extending out of the sleeve, and the first connecting mating portion 221 can be a groove formed on the rotating tooth 22, with the claw engaged in the groove.

[0085] Or, such as Figure 9 and Figure 10 As shown, a second connecting part 44 is provided at the other end of the sleeve, and a second connecting part 32 and a third connecting part 33 are provided on the pen refill. The second connecting part 32 is close to the pen tip 31, and the third connecting part 33 is away from the pen tip 31; a third connecting part 222 is provided on the rotating tooth 22.

[0086] The second connecting part 44 and the second connecting mating part 32 are assembled together, and the third connecting part 33 and the third connecting mating part 222 are assembled together.

[0087] Specifically, the sleeve is connected to the pen refill via the second connecting part so that it can rotate with the pen refill. At the same time, the rotating tooth 22 and the pen refill 3 are connected by the third connecting part 33 and the third connecting mating part 222 so that the pen refill 3 can rotate with the rotating tooth 22, thereby meeting the usage requirements of switching the angle of the sleeve.

[0088] Similarly, the specific structure of the connecting part and the connecting mating part can adopt the mating method of tongue and slot, or the mating method of claw and slot.

[0089] In one embodiment of this application, the inner wall of the pen barrel 1 is provided with a plurality of first anti-shake mating parts 13, and a gap is formed between two adjacent first anti-shake mating parts 13;

[0090] The interval is configured to allow passage for the second anti-shake mating part 41 during the extension and retraction of the pen refill 3 in the pen barrel 1.

[0091] Specifically, to better prevent wobbling, multiple first anti-wobbling mating parts 13 can be arranged around the opening 11 on the inner wall of the pen barrel 1. Correspondingly, the anti-wobbling component 4 is provided with corresponding second anti-wobbling mating parts 41. In the writing state, the first anti-wobbling mating parts 13 and the corresponding second anti-wobbling mating parts 41 are pressed and abutted together.

[0092] In one embodiment, in order to ensure that the pen tip 31 of the pen refill 3 can smoothly extend out of the pen barrel 1 during the pressing process, and that the pen tip 31 can smoothly retract from the outside of the pen barrel 1 to the inside of the pen barrel 1.

[0093] When the pen tip 31 of the pen refill 3 is retracted into the pen barrel 1, the first anti-shake engagement part 13 and the second anti-shake engagement part 41 are misaligned along the length of the pen barrel 1. Specifically, when the pen tip 31 is inside the pen barrel 1 and the user presses the pen to extend the pen tip 31 from the pen barrel 1, the first anti-shake engagement part 13 and the second anti-shake engagement part 41 are misaligned in this state. As the anti-shake component 4 and the pen refill 3 move towards the outside of the pen barrel 1, the first anti-shake engagement part 13 will not obstruct the normal movement of the second anti-shake engagement part 41, ensuring that the second anti-shake engagement part 41 extends out of the opening 11 past the first anti-shake engagement part 13.

[0094] The pen tip 31 of the pen refill 3 extends from the inside of the pen barrel 1 to its maximum travel point on the outside of the pen barrel 1. Along the length of the pen barrel 1, from the outside to the inside, the second anti-sway mating part 41 and the first anti-sway mating part 13 are arranged sequentially, with the second anti-sway mating part 41 located outside the first anti-sway mating part 13. Specifically, after the pen tip 31 of the pen refill 3 extends from the inside of the pen barrel 1, when it reaches its maximum travel point, the rotating tooth 22 disengages from the positioning rib 14 of the pen barrel 1 and engages with the sliding tooth 21 to generate a certain angle of rotation. The rotating tooth 22 drives the anti-sway component 4 to rotate synchronously, adjusting the angular position of the second anti-sway mating part 41 relative to the first anti-sway mating part 13 in the circumferential direction. Thus, when the user releases their grip, the pen tip 31 retracts again, and the second anti-sway mating part 41, during its retraction towards the inside of the pen barrel 1, is blocked by the first anti-sway mating part 13, causing the pen tip 31 to be clamped in the opening 11.

[0095] In one embodiment, the pen tip 31 of the pen refill 3 extends beyond the pen barrel 1 in a writing state. Along the length of the pen barrel 1, from the outside to the inside, the second anti-wobbling fitting part 41 and the first anti-wobbling fitting part 13 are arranged sequentially, with the second anti-wobbling fitting part 41 tightly abutting against the first anti-wobbling fitting part 13. Specifically, in the writing state, the first anti-wobbling fitting part 13 and the second anti-wobbling fitting part 41 are pressed together to prevent wobbling.

[0096] When the pen tip 31 of the pen refill 3 extends outward from the writing state to its maximum travel position outside the pen barrel 1, the first anti-wobbling engagement part 13 and the second anti-wobbling engagement part 41 are misaligned along the length of the pen barrel 1. Specifically, after the user applies pressure to the push-button 12 on the pen barrel 1, the pen refill 3 will move outward again, causing the second anti-wobbling engagement part 41 to disengage from the first anti-wobbling engagement part 13. Furthermore, when the pen tip 31 extends to its maximum travel position, the rotating tooth 22 disengages from the positioning rib 14 of the pen barrel 1 and rotates at a certain angle in conjunction with the sliding tooth 21, causing the first anti-wobbling engagement part 13 and the second anti-wobbling engagement part 41 to be misaligned.

[0097] The technical solution of this utility model has the following technical effects compared with the prior art: By setting an anti-shake component in the pen barrel, a first anti-shake mating part for cooperating with the anti-shake component is set in the pen barrel near the opening. When the pen tip extends out of the pen barrel and is in the writing state, the first anti-shake mating part contacts the second anti-shake mating part of the anti-shake component, thereby clamping the pen tip and the anti-shake component in the opening of the pen barrel. In this way, during the writing process, the pen tip is effectively held by the anti-shake component and will not shake in the opening, thereby reducing pen tip shaking and improving the user's writing experience.

[0098] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
