Description

Technical Field

[0001] This utility model belongs to the field of writing instrument technology, and in particular relates to a fun writing pen. Background Technology

[0002] The press head of a push-button writing pen is usually mounted on the top of the pen barrel, with no exposed parts between the barrel and the press head, resulting in a relatively simple design. Moreover, since the press head is directly attached to the top of the refill assembly, the pressing feel is relatively poor. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a fun writing pen, in which the first and second shaping parts are combined or separated when switching between the state of pressing to extend or retract the pen core, making it highly fun to use.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fun writing pen, including a pen barrel, a pen core assembly, and a pressing head. The pressing head and the pen core assembly are connected by an elastic element. The outer wall of the pen barrel forms a second shaped part, and the pressing head forms a first shaped part. When an external force is applied to the pressing head, the elastic element is compressed so that the pressing head and the top of the pen barrel come into contact. The first shaped part and the second shaped part are combined to form a complete shaped part. The pen core of the pen core assembly extends out of the pen barrel or retracts into the pen barrel.

[0005] This invention features a first shaped part on the press head and a second shaped part on the top of the pen barrel. The press head and the pen refill assembly are connected by an elastic element. When the elastic element is switched between compressed and unfolded states, the first and second shaped parts can be combined to form a complete shaped part or separated from each other, increasing the fun of use. At the same time, the pen refill assembly completes the action of extending or retracting the pen refill, combining fun and functionality. The press head and the pen refill assembly are connected by a relatively long elastic element, which provides greater elasticity, making it comfortable for the user to press down on the press head.

[0006] Furthermore, the elastic element includes a first elastic connecting segment, a second elastic connecting segment, and a deformation segment located between the first and second elastic connecting segments. The first elastic connecting segment is detachably connected to the pressing head, and the second elastic connecting segment is detachably connected to the pen refill assembly. When the deformation segment extends, the pressing head and the pen barrel move away from each other. The first elastic connecting segment facilitates detachable assembly and connection with the pressing head, and the second elastic connecting segment facilitates detachable assembly and connection with the pen refill assembly. When the deformation segment extends, it acts as a neck between the first and second shaping parts, resulting in a novel and interesting overall design that can attract consumers.

[0007] Furthermore, the first elastic connecting segment, the deformation segment, and the second elastic connecting segment are arranged concentrically and coaxially. In this structure, when the deformation segment is compressed, the first and second shaping parts can be aligned and joined together, preventing displacement and improving the aesthetics of the shaping parts.

[0008] Furthermore, the first elastic connecting segment is a cylindrical spring, and a cylindrical first mounting segment is formed inside the pressing head. The inner diameter of the first elastic connecting segment is smaller than the outer diameter of the first mounting segment. The first elastic connecting segment extends spirally along a first direction, fitting into the outer circumference of the first mounting segment and rotating relative to the first mounting segment along the first direction. When the first elastic connecting segment and the first mounting segment stop rotating relative to each other, a tight fit is achieved. Utilizing the characteristics of the first elastic connecting segment, a tight and stable connection between the first elastic connecting segment and the first mounting segment is cleverly achieved. The assembly of the first elastic connecting segment and the first mounting segment is simple, and after assembly, their concentricity is guaranteed, preventing misalignment. The first elastic connecting segment and the first mounting segment are easy to disassemble, facilitating the replacement of the pressing head.

[0009] Furthermore, the second elastic connecting segment is a cylindrical spring, and a cylindrical second mounting segment is formed at the top of the pen refill assembly. The inner diameter of the second elastic connecting segment is smaller than the outer diameter of the second mounting segment. The second elastic connecting segment extends spirally along a first direction, fitting into the outer circumference of the second mounting segment, and rotates relative to the second mounting segment along the first direction. When the second elastic connecting segment and the second mounting segment stop rotating relative to each other, a tight fit is achieved. Utilizing the characteristics of the second elastic connecting segment, a tight and stable connection between the second elastic connecting segment and the second mounting segment is cleverly achieved. The assembly of the second elastic connecting segment and the second mounting segment is simple, and after assembly, their concentricity is guaranteed, preventing misalignment.

[0010] Furthermore, the first mounting section has a first blocking portion with an increased outer diameter, and the end of the first elastic connecting section abuts against the first blocking portion; the second mounting section has a second blocking portion with an increased outer diameter, and the end of the second elastic connecting section abuts against the second blocking portion. The first and second blocking portions provide positioning for the assembly of the first and second elastic connecting sections, ensuring the stability and effectiveness of the assembly structure, preventing the first elastic connecting section from excessively extending into the pressing head, preventing the second elastic connecting section from excessively extending into the pen barrel, and preventing the exposed deformable section from being too long or too short.

[0011] Furthermore, the deformable segment is frustoconical, with the outer diameter of the end connected to the first elastic connecting segment being smaller than the outer diameter of the end connected to the second elastic connecting segment. This design makes the pressing head more stable when external force is applied, and also results in a more aesthetically pleasing appearance.

[0012] Furthermore, the first sculpted part is a head, and the second sculpted part is a torso; the sculpted parts can be human figures, animal figures, or plant figures. This provides a high degree of selectivity in the sculpted parts and enhances their aesthetic appeal.

[0013] Furthermore, the elastic element is a spring, and the first elastic connecting section, the deformation section, and the second elastic connecting section are integrally connected. The elastic element is made of simple materials and is easy to process.

[0014] The beneficial effects of this utility model are as follows: A first shaped part is designed on the pressing head, and a second shaped part is designed on the top of the pen barrel. The pressing head and the pen refill assembly are connected by an elastic element. While the pen refill assembly completes the refill action, the elastic element switches between compressed and unfolded states. The first and second shaped parts can be combined to form a complete shaped part, or separated from each other, increasing the fun of use and combining fun and functionality. The pressing head and the pen refill assembly are connected by a long elastic element, which provides greater elasticity, making it comfortable for the user to press down the pressing head. The structural design and installation method of the elastic element ensure that the first and second shaped parts can be aligned and combined, preventing them from shifting, and improving the aesthetics of the shaped part.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0028] like Figures 1-6 As shown, a fun writing pen includes a pen barrel 1, a pen refill assembly 2 located inside the pen barrel 1, and a pressing head 3. The pen refill assembly 2 includes a pen refill 23. The pressing head 3 is not directly assembled and connected to the pen barrel 1, but is connected to the pen refill assembly 2 through an elastic member 4. When the elastic member 4 is in a naturally extended state, the pressing head 3 and the top of the pen barrel 1 are far apart from each other.

[0029] The outer wall of the pen barrel 1 forms a second shaped part 52, and the pressing head 3 forms a first shaped part 51. When an external force is applied to the pressing head 3, the elastic member 4 is compressed, thereby causing the pressing head 3 to contact the top of the pen barrel 1. The first shaped part 51 and the second shaped part 52 are combined to form a complete shaped part 5, such as... Figure 6 The dashed box in the middle shows the shaping part 5. At the same time, driven by the elastic element 4, the pen tip 23 of the pen tip assembly 2 extends out of the pen barrel 1 or retracts into the pen barrel 1. That is, when the elastic element 4 switches between the compressed and extended states, the first shaping part 51 and the second shaping part 52 are combined or separated, which is highly interesting to use. At the same time, the pen tip assembly 2 completes the action of extending the pen tip or retracting the pen tip 23, combining fun and functionality.

[0030] Specifically, the first shaping part 51 can be the head, and the second shaping part 52 can be the torso, so that the shaping part 5 formed by the combination of the first shaping part 51 and the second shaping part 52 can be a human figure, an animal figure, or a plant figure.

[0031] In this embodiment, the first shaping part 51 is the bear's head, and the second shaping part 52 is the bear's torso. When the elastic member 4 extends, the head and torso separate, with the elastic member 4 serving as the neck connecting the head and torso. At this time, the elastic member 4 is relatively long, thus partially exposed to the outside. When an external force is applied to the pressing head 3, causing the pressing head 3 and the top of the pen barrel 1 to approach and contact each other, the head and torso combine to form a complete bear, making it highly engaging. Since the elastic member 4 is connected between the pressing head 3 and the pen refill assembly 2, pressing down the pressing head 3 can drive the pen refill assembly 2 to extend. During repeated pressing down of the pressing head 3, the pen refill repeatedly extends and retracts from the pen barrel 1, and the first shaping part 51 and the second shaping part 52 repeatedly separate or combine, greatly increasing the engaging nature of the user experience. Moreover, since the pressing head 3 and the pen refill assembly 2 are connected by the relatively long elastic member 4, the elastic force provided by the elastic member 4 is greater, providing a comfortable feel when the user presses down the pressing head 3.

[0032] like Figure 7 , Figure 8 As shown, the elastic element 4 includes, from top to bottom, a first elastic connecting section 41, a deformation section 43, and a second elastic connecting section 42. The first elastic connecting section 41 is detachably connected to the pressing head 3, and the second elastic connecting section 42 is detachably connected to the pen refill assembly 2. When the deformation section 43 extends, the pressing head 3 and the pen barrel 1 move away from each other. The specific structure of the elastic element 4 is not limited here; it can be a spring or other elastic material.

[0033] In this embodiment, the elastic element 4 is a spring. The first elastic connecting section 41, the deformation section 43, and the second elastic connecting section 42 are integrally connected. The first elastic connecting section 41 and the second elastic connecting section 42 are cylindrical springs, and the deformation section 43 is a frustoconical spring. The outer diameter of the end connected to the first elastic connecting section 41 is smaller than the outer diameter of the end connected to the second elastic connecting section 42. In other words, with Figure 8 Taking the direction shown as an example, the outer diameter of the upper end of the deformable segment 43 is smaller than the outer diameter of the lower end. Furthermore, the first elastic connecting segment 41, the deformable segment 43, and the second elastic connecting segment 42 are concentrically and coaxially arranged, with their central axes all being... Figure 8 The L-line in the middle allows the first shaping part 51 and the second shaping part 52 to be aligned and joined together when the deformed segment 43 is compressed, thus preventing them from shifting.

[0034] like Figure 11As shown, a columnar first mounting section 31 is formed inside the pressing head 3. The end of the first mounting section 31 away from the pen barrel 1 has a first blocking part 32 with an increased outer diameter. The inner diameter of the first elastic connecting section 41 is slightly smaller than the outer diameter of the first mounting section 31. The first elastic connecting section 41 extends spirally along a first direction. During assembly, an external force is first applied to fit the first elastic connecting section 41 into the outer periphery of the first mounting section 31. Then, it rotates relative to the first mounting section 31 along the first direction. When the first elastic connecting section 41 and the first mounting section 31 stop rotating relative to each other, the first elastic connecting section 41 returns to its original shape, and the two achieve a tight fit.

[0035] Specifically, with Figure 8 Taking the example shown, the first direction is clockwise, that is, the first elastic connecting segment 41 extends spirally in the clockwise direction. Since the inner diameter of the first elastic connecting segment 41 is smaller than the outer diameter of the first mounting segment 31, the first elastic connecting segment 41 is first opened with a tool so that it fits into the outer circumference of the first mounting segment 31. Then, an external force is applied to make the first elastic connecting segment 41 and the first mounting segment 31 rotate relative to each other. At this time, under the action of the external force, the inner diameter of the first elastic connecting segment 41 expands slightly, and it can be smoothly inserted into the first mounting segment 31. That is, the length of the first elastic connecting segment 41 inserted into the outer circumference of the first mounting segment 31 gradually increases until the end of the first elastic connecting segment 41 abuts against the end face of the first blocking part 32. When the first elastic connecting segment 41 and the first mounting segment 31 stop rotating relative to each other, the first elastic connecting segment 41 recovers its deformation under the action of no external force, and it achieves tight fit with the first mounting segment 31. The first elastic connecting segment 41 will not easily detach from the first mounting segment 31.

[0036] like Figure 9 , Figure 10 As shown, the top of the pen refill assembly 2 forms a columnar second mounting section 21, and the end of the second mounting section 21 near the pen barrel 1 has a second blocking portion 22 with an increased outer diameter. The inner diameter of the second elastic connecting section 42 is slightly smaller than the outer diameter of the second mounting section 21. The second elastic connecting section 42 extends spirally along the first direction. During assembly, an external force is first applied to fit the second elastic connecting section 42 into the outer periphery of the second mounting section 21, and then it rotates relative to the second mounting section 21 along the first direction. When the second elastic connecting section 42 and the second mounting section 21 stop rotating relative to each other, the second elastic connecting section 42 returns to its original shape, and the two achieve a tight fit.

[0037] Specifically, with Figure 8 , Figure 10Taking the example shown, the first direction is clockwise, that is, the second elastic connecting segment 42 extends spirally in the clockwise direction. Since the inner diameter of the second elastic connecting segment 42 is smaller than the outer diameter of the second mounting segment 21, the second elastic connecting segment 42 is first opened with a tool so that it fits into the outer circumference of the second mounting segment 21. Then, an external force is applied to make the second elastic connecting segment 42 and the second mounting segment 21 rotate relative to each other. At this time, under the action of the external force, the inner diameter of the second elastic connecting segment 42 expands slightly, and it can be smoothly inserted into the second mounting segment 21. That is, the length of the second elastic connecting segment 42 inserted into the outer circumference of the second mounting segment 21 gradually increases until the end of the second elastic connecting segment 42 abuts against the end face of the second blocking part 22. When the second elastic connecting segment 42 and the second mounting segment 21 stop rotating relative to each other, the second elastic connecting segment 42 recovers its deformation under the action of no external force, and it achieves a tight fit with the second mounting segment 21. The second elastic connecting segment 42 will not easily detach from the second mounting segment 21.

[0038] The above structure enables the detachable installation of the first elastic connecting section 41 and the pressing head 3, as well as the detachable installation of the second elastic connecting section 42 and the pen refill assembly 2. The installation structure is relatively simple, facilitating the replacement of the first shaping part 51. The same kit can provide multiple options for the first shaping part 51, further enhancing the user experience by changing different first shaping parts 51. Moreover, after installation, the concentricity of the first elastic connecting section 41, the deformation section 43, and the second elastic connecting section 42 is guaranteed, preventing misalignment after assembly that could cause the first shaping part 51 and the second shaping part 52 to not be fully aligned.

[0039] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
