Description

Technical Field

[0001] This utility model relates to the field of stationery, and in particular to a novel press-type pen. Background Technology

[0002] In daily life, push-button pens are popular due to their flexibility. A push-button pen consists of a barrel, a refill, and a spring-loaded plate for refill positioning. The spring-loaded plate has a positioning protrusion at its tip. In use, the user presses a button at the end of the barrel to move the spring-loaded plate downwards. When the positioning protrusion on the spring-loaded plate engages with an opening on the barrel surface, the refill is extended and remains stable. To retract, the user presses the positioning protrusion back into the barrel. However, if the spring-loaded plate breaks or its deformation performance deteriorates, it will no longer be able to maintain the extended position of the refill, rendering the push-button pen unusable. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a novel press pen.

[0004] The technical solution adopted by this utility model is as follows: a novel press pen, including a pen barrel, a pen cap, and a pen refill. A spring is sleeved on the bottom end of the pen refill. A pen clip is provided on the pen barrel. A linkage shaft is provided between the pen refill and the pen cap. The linkage shaft is slidably connected inside the pen barrel. A locking protrusion is provided on the side of the linkage shaft. A locking hole is provided on the side of the pen barrel. A locking block is provided at the end of the pen clip. The locking block extends into the locking hole and locks with the locking protrusion.

[0005] Furthermore, a guide boss is provided on the side of the linkage shaft, and a guide groove is provided on the inner surface of the pen barrel, with the guide boss slidably connected in the guide groove.

[0006] Furthermore, the guide boss is located directly above the snap-fit ​​boss. The guide boss, the snap-fit ​​boss, and the guide groove are all in two sets and are all arranged at equal angles along the circumferential direction. The guide groove includes a connected guide inclined surface and a guide straight groove, and the guide straight groove is located at the highest point of the guide inclined surface.

[0007] Furthermore, the upper end of the guide boss is provided with an inclined guide surface, which is in contact with the guide slope.

[0008] Furthermore, the pen clip is fitted onto the top of the pen barrel, and the lower side of the snap-fit ​​block is provided with a snap-fit ​​groove, which snaps into the snap-fit ​​protrusion.

[0009] Furthermore, the pen clip has a through hole, the pen cap is disposed in the through hole, the inner wall of the through hole has an anti-detachment groove, and the side of the pen cap has a limiting block, which is slidably connected to the anti-detachment groove.

[0010] Compared with the prior art, this utility model has the following beneficial effects:

[0011] In this invention, a linkage shaft is provided between the pen refill and the pen cap. The linkage shaft is slidably connected inside the pen barrel. A locking protrusion is provided on the side of the linkage shaft, and a locking hole is provided on the side of the pen barrel. A locking block is provided at the end of the pen clip. When writing, the user presses the pen cap to engage the locking block with the locking protrusion. After writing, the user pushes the pen clip outward to disengage the locking block from the locking protrusion, thus retracting the pen refill. This product achieves the positioning effect of the extended pen refill through a more stable and fatigue-resistant pen clip, thereby ensuring the long-term use of the press-type pen.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] This utility model proposes a novel push-button pen, comprising a pen barrel 1, a pen cap 2, and a pen refill. A spring is fitted onto the bottom end of the pen refill, and a pen clip 3 is provided on the pen barrel 1. This part of the structure can be referenced from a traditional push-button pen. Figure 1 This product features a linkage shaft 4 between the pen refill and the pen cap 2. The linkage shaft 4 is slidably connected within the pen barrel 1. A locking protrusion 41 is located on the side of the linkage shaft 4, and a locking hole 11 is located on the side of the pen barrel 1. A locking block 31 is located at the end of the pen clip 3, extending into the locking hole 11. In use, the user presses the pen cap 2, causing the linkage shaft 4 to move downwards. The locking protrusion 41 moves to below the locking block 31. After releasing the pen cap 2, a spring on the pen refill pushes the pen refill and the linkage shaft 4 upwards. During this rebound, the locking protrusion 41 engages with the locking block 31, resulting in the following state: Figure 4 As shown, the user can then write. After writing, the pen clip 3 is pushed outwards, causing the locking protrusion 41 to disengage from the locking block 31, allowing the pen retract into the pen barrel 1. In the prior art, the pen clip 3 is usually made of thicker injection-molded material or a flexible metal sheet. Compared to traditional push-button pens, this product maintains the pen retractor in the extended position through the more fatigue-resistant pen clip 3, thus ensuring the long-term stable use of the push-button pen.

[0023] See Figure 1 The linkage shaft 4 has a guide boss 42 on its side and a guide groove 12 on the inner surface of the pen barrel 1. The directional control of the linkage shaft 4 during its up-and-down sliding process is achieved through the sliding connection between the guide boss 42 and the guide groove 12.

[0024] See Figure 1 and Figure 2 The guide boss 42 is located directly above the snap-fit ​​boss 41. The guide boss 42, the snap-fit ​​boss 41, and the guide groove 12 are all in two sets and are arranged at equal angles along the circumferential direction. The guide groove 12 includes a connected guide ramp 121 and a guide straight groove 122, with the guide straight groove 122 located at the highest point of the guide ramp 121. When the pen cap 2 is pressed, the guide boss 42 moves along the guide straight groove 122 to the bottom; see reference. Figure 5The guide ramp 121 is distributed on the arc-shaped surface inside the pen barrel 1. After the pen cap 2 is released, the guide boss 42 rises along the guide ramp 121, and at the same time drives the linkage shaft 4 to rotate. When the locking boss 41 rises to the locking hole 11 of the pen barrel 1, the locking boss 41 just abuts against the locking block 31.

[0025] Specifically, the upper end of the guide boss 42 is provided with an inclined guide surface 421. The inclined guide surface 421 can better fit with the guide slope 121, and at the same time, it can ensure that the process of the guide boss 42 moving from the guide straight groove 122 to the guide slope 121 is smoother.

[0026] See Figure 1 and Figure 3 The pen clip 3 is sleeved on the top of the pen barrel 1. The lower side of the snap-fit ​​block 31 is provided with a snap-fit ​​groove 311. The snap-fit ​​protrusion 41 enters into the snap-fit ​​groove 311 and snaps into it. The snap-fit ​​groove 311 can better prevent the snap-fit ​​protrusion 41 from disengaging from the snap-fit ​​state and ensure the normal use of the press pen.

[0027] See Figure 1 and Figure 2 The pen clip 3 is provided with a through hole 32, and the pen cap 2 is disposed in the through hole 32. The inner wall of the through hole 32 is provided with an anti-detachment groove 321, and the side of the pen cap 2 is provided with a limiting block 21. The limiting block 21 is slidably connected in the anti-detachment groove 321 to ensure that the pen cap 2 is always connected to the pen clip 3 during use.

[0028] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
