Description

Technical Field

[0001] This utility model relates to the field of ballpoint pen technology, specifically a novel ultra-high molecular weight wear-resistant, stretchable, and variable angle ballpoint pen. Background Technology

[0002] As we all know, the performance and user experience of existing ballpoint pens, as an indispensable writing tool in daily life, have always been the focus of stationery design. Traditional ballpoint pens are mostly simple in design and have limited functions, making it difficult to meet modern people's needs for diversified, convenient and personalized writing tools.

[0003] Specifically, traditional ballpoint pens are often inconvenient to adjust when adjusting the writing angle and length. Users usually need to use external tools to make adjustments, which not only affects the ease of use but may also damage the pen itself. At the same time, because the adjustment method is not flexible enough, users cannot make fine adjustments according to their own writing habits and needs, thus affecting the writing experience and effect. In addition, traditional ballpoint pens are also lacking in wear resistance and durability, and the protective shell material of the pen is of poor quality, which reduces its service life.

[0014] In order to significantly improve the writing quality and user experience of the pen, the improvement of this utility model is that the pen core uses water-based ink.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a novel ultra-high molecular weight polymer wear-resistant stretchable and variable angle ballpoint pen, which has the following beneficial effects:

[0017] This new type of ultra-high molecular weight polymer wear-resistant, extendable, and adjustable-angle ballpoint pen features a rotating rod and a turntable. Users can adjust the turntable's angle to adjust the pen's overall tilt angle, meeting different writing needs. This not only improves the pen's flexibility but also enhances the user experience. A fixed rod and a sliding rod are also included. Rotating the sliding rod, with the assistance of a threaded rod, raises and lowers the rod, allowing users to adjust the pen's length. This not only facilitates adjusting the pen's length according to writing needs but also makes the pen more portable and easier to store. A locking mechanism within the case, activated by a spring, can secure the fixed rod and sliding rod, preventing the sliding rod from slipping or falling off during use. This stable fixing mechanism ensures the pen's writing stability and accuracy. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4 A novel ultra-high molecular weight polymer wear-resistant, extendable, and variable-angle ballpoint pen includes a protective shell 1, a turntable 5, and a fixing rod 7. The protective shell 1 has a detachable protective plate 3 at its upper end, and a rotating rod 4 at its upper end. The turntable 5 is mounted on the rotating rod 4 and is rotatably connected to it. An adjusting rod 6 is located inside the turntable 5 and is rotatably connected to the turntable 5. The turntable 5 has an opening at its upper end, through which the adjusting rod 6 is slidably connected. The fixing rod 7 is located above the adjusting rod 6 and has a groove inside. A threaded rod 12 and a sliding rod 8 are located within the groove. The threaded rod 12 passes through the groove, and the sliding rod 8 is threaded onto and slidably connected to the threaded rod 12. The sliding rod 8 fits snugly against the groove and is slidably connected. A fixing box 10 is located on the upper side wall of the fixing rod 7, and a spring 13 and an auxiliary spring 14 are located inside the fixing box 10. The auxiliary plate 14 and locking rod 15 are provided. The spring 13 is symmetrically arranged inside the fixed box 10. One end of the spring 13 is connected to the inner side wall of the fixed box 10, and the other end is connected to the auxiliary plate 14. The auxiliary plate 14 is on the bottom wall of the fixed box 10 and slidably connected to it. The locking rod 15 passes through the fixed box 10 and the auxiliary plate 14. The side wall of the fixed rod 7 is provided with a fixing hole. The side wall of the sliding rod 8 is provided with multiple auxiliary holes. The fixing hole and the auxiliary hole can coincide. The locking rod 15 passes through the fixing hole and the auxiliary hole and slidably connects to them. A large-capacity pen refill 11 is provided inside the protective shell 1. The pen refill 11 is detachably connected to the protective shell 1. The upper side wall of the fixed box 10 is provided with a limit hole. The upper side wall of the auxiliary plate 14 is provided with a support block 16. The support block 16 passes through the limit hole and slidably connects to it. The upper end of the sliding rod 8 is provided with a turning block 9.

[0025] During use, when the angle needs to be adjusted to suit different writing needs, the user can first forcefully rotate the rotating rod 4 located at the upper end of the protective plate 3. Because the rotating rod 4 and the turntable 5 are connected by a damped rotation, this connection allows the user to smoothly rotate the turntable 5 when a certain force is applied. As the rotating rod 4 rotates, the turntable 5 also rotates, allowing for direction adjustment. While adjusting the angle of the turntable 5, the user can also forcefully rotate the adjusting rod 6. The adjusting rod 6 rotates within the opening, allowing for fine-tuning of the pen tip angle. When the user wishes to adjust the length of the pen to suit different writing postures or grip habits, they can pull the support block 16. The auxiliary plate 14 moves with the support block 16, the spring 13 retracts, and the locking rod 15... As the auxiliary plate 14 moves, the locking rod 15 disengages from the fixing hole and the auxiliary hole. Then, the rotating block 9 is turned, and the sliding rod 8 rotates accordingly. Since the sliding rod 8 is threadedly connected to the threaded rod 12, the sliding rod 8 will slide up and down on the threaded rod 12, thereby changing its length extending from the fixing rod 7. After adjusting to a suitable length, the corresponding suitable auxiliary hole can be aligned with the fixing hole. The support block 16 is released, and the spring 13 extends under its own elastic force. The auxiliary plate 14 moves with the extension of the spring 13, and the locking rod 15 moves accordingly, passing through the fixing hole and the auxiliary hole to further lock, thereby improving the stability and reliability of the entire pen. This allows the pen to meet the writing needs of different users and provides a more comfortable and convenient writing experience.

[0026] In actual use, it is necessary to protect the pen refill 11 from external contaminants such as dust and dirt, and keep the pen refill 11 clean and write smoothly. In order to meet the above requirements, in this embodiment, a protective cover 2 is provided on the outside of the protective shell 1, and the protective cover 2 is detachably connected to the protective shell 1.

[0027] In practical use, it is required to have excellent wear resistance, impact resistance and corrosion resistance. In order to meet the above requirements, in this embodiment, the protective shell 1, the fixing rod 7 and the sliding rod 8 are all made of ultra-high molecular weight polyethylene.

[0028] In actual use, it is necessary to be able to observe the usage of the pen refill 11 at any time, including the remaining amount of the pen refill 11. In order to meet the above requirements, in this embodiment, the side wall of the protective shell 1 is made of transparent material.

[0029] In practical use, it is necessary to significantly improve the writing quality and user experience of the pen. In order to meet the above requirements, in this embodiment, the pen refill 11 uses water-based ink.
