Description

Technical Field

[0001] This utility model relates to the field of writing instruments, specifically to a gourd-shaped spinning pen. Background Technology

[0002] Pens are consumables widely used in daily life and office work. With the diversification of functions and shapes, in addition to meeting writing performance requirements, many pens are constantly pursuing improvements and optimizations in terms of portability and fun in terms of structure and appearance.

[0003] Due to the increased mental stress experienced by people during long periods of study and work, failure to release this stress can affect their mood. Some people relieve stress and adjust their mood by fiddling with pen tubes or using stress-relieving tools such as "squeezable toys," "finger drops," or "radish knives." In recent years, creative pens that combine functionality, manipulation, and writing features have emerged on the market (such as "spinning pens" with spinning wheels, mazes, or uniquely shaped decorations). These products attract users who seek interactive experiences by increasing the fun of use and providing stress relief.

[0004] Therefore, there is an urgent need to design a gourd-shaped pen that can attract users to buy and use it through its appearance, while also providing stress relief through interactive operations such as rotating and manipulating it, thus satisfying users' needs for both practicality and psychological adjustment in writing tools. Utility Model Content

[0005] The purpose of this utility model is to provide a gourd-shaped spinning pen that, while meeting the needs of conventional writing, achieves elastic sliding and circumferential rotation of the waist shell relative to the bottom shell through reasonable guidance, limiting and elastic components, thus providing multiple ways to play with (decompress) it.

[0006] The technical solution adopted by this utility model to solve the above problems is: a gourd-shaped rotating pen, including a pen shell and a pen core disposed in the pen shell. The pen shell is telescopic and includes a waist shell and a bottom shell. The waist shell slides and rotates elastically relative to the bottom shell. The pen core is fixedly disposed in the bottom shell. When the pen shell is shortened, the pen core tip extends out from the end of the waist shell. When the pen shell is extended, the pen core tip retracts into the waist shell. The pen shell can be locked by clamping the waist shell and the bottom shell when it is at its shortest or longest length.

[0007] Preferably, both the waist shell and the bottom shell adopt a detachable connection structure. The waist shell includes an upper waist shell and a lower waist shell that are interlocked and fixed to each other, and the bottom shell includes an upper bottom shell and a lower bottom shell that are interlocked and fixed to each other.

[0008] Preferably, a bearing is fixedly installed inside the waist shell, the bearing is slidably sleeved with the bottom shell and is provided with a compression spring, the compression spring is used to push the bearing together with the waist shell away from the bottom shell.

[0009] Preferably, the upper waist shell is provided with a mounting groove that matches the outer diameter of the bearing outer ring, the inner end of the lower waist shell is provided with a first annular boss, a first limiting shoulder is provided in the mounting groove, one end of the bearing outer ring is tightly attached to the first limiting shoulder, after the lower waist shell and the upper waist shell are snapped together and fixed, the end of the first annular boss is tightly attached to the other end of the bearing outer ring, and the bottom upper shell is provided with a placement cylinder for accommodating the pen refill tube, and the placement cylinder is provided with a guide part that matches the inner diameter of the bearing inner ring, so that the bearing can slide axially along the guide part.

[0010] Preferably, one end of the placement tube is provided with a core outlet, the outer periphery of which is provided with an annular groove, and the inner side of the upper end of the waist shell is provided with an annular protrusion that is adapted to engage with the annular groove, so that the core outlet of the placement tube extends out relative to the upper end of the waist shell and is then locked in place.

[0011] Preferably, the placement cylinder is further provided with a second limiting shoulder, which is located at the end of the guide portion away from the core portion. Its outer diameter is larger than that of the compression spring. The compression spring is sleeved on the guide portion and is located between the inner ring of the bearing and the second limiting shoulder.

[0012] Preferably, the placement tube is provided with a third limiting shoulder to prevent the pen refill from coming out of the refill section. One end of the pen refill tube contacts and limits the third limiting shoulder, so that the pen tip can pass through but the pen refill tube cannot. The lower shell is provided with a second annular protrusion at its inner end. One end of the pen refill tube is located in the second annular protrusion. After the upper shell and the lower shell are snapped together, the inner end face of the second annular protrusion is tightly attached to one end of the pen refill tube, so that the pen tip extends out of the refill section end face of the placement tube.

[0013] Preferably, the guide portion is provided with an inner cavity that is compatible with the pen refill tube. The diameter of the inner cavity gradually decreases towards the end from which the pen refill is inserted, so that the outer surface of the pen refill tube is pressed tightly against the inner wall of the inner cavity and fixed after being pushed in.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0029] Example:

[0030] See Figure 1 - Figure 5 In this embodiment, a gourd-shaped rotating pen is disclosed, which is used for daily writing and also as a playful stress-relieving tool. Specifically, it includes a pen shell 11 and a pen core 12 disposed within the pen shell 11. The pen shell 11 is telescopic and includes a waist shell 13 and a bottom shell 14. The waist shell 13 (via an elastic element and a rotating element) elastically slides and rotates relative to the bottom shell 14. The pen core 12 is fixedly disposed within the bottom shell 14. When the pen shell 11 is shortened, the pen tip 121 of the pen core 12 extends out from the end of the waist shell 13. When the pen shell 11 is extended, the pen tip 121 of the pen core 12 retracts into the waist shell 13. The pen shell 11 can be locked by the waist shell 13 and the bottom shell 14 when it is at its shortest or longest extension.

[0031] Specifically, in this embodiment, in addition to meeting the user's daily writing needs, the present invention also includes the following three usage (decompression) methods:

[0032] Pull-pull (axial push-pull locking / unlocking): See Figure 6 Hold the bottom shell 14 with one hand and the waist shell 13 with the other. Pull the pen shell 11 to its longest extension and lock it. Press to release the lock, then press the waist shell 13 until its end face contacts the end face of the bottom shell 14. The pen shell 11 will retract to its shortest extension and lock. Repeat the above operation to release the pressure.

[0033] Press-to-jump (ejector-type elastic bounce): See Figure 7 In this embodiment, the waist shell 13 is elastically slidably connected to the bottom shell 14, and the elastic force is an outward pushing force, which can drive the waist shell 13 away from the bottom shell 14, causing the pen shell 11 to extend as a whole. Before using this method, the pen shell 11 must be in an extended and unlocked state. At this time, the bottom shell 14 can be held in the hand, leaving the thumb exposed. By pressing the waist shell 13 with the thumb, it can be moved towards the bottom shell 14, causing the pen shell 11 to shorten as a whole and not lock. After the thumb is released, the waist shell 13 will pop out away from the bottom shell 14 under the elastic force, forming a "bouncing" motion. The above operation is repeated to decompress.

[0034] Rotation by turning (circumferential turning produces continuous rotation): See Figure 8The prerequisites for using this method are the same as for the press-and-jump (the pen shell 11 is in an extended and unlocked state). The grip is also similar. Hold the bottom shell 14 with your hand, and use your thumb to rotate the waist shell 13 relative to the bottom shell 14 by flicking it. Repeat this flicking motion to make the waist shell 13 rotate continuously to release the pressure.

[0035] This utility model also includes a pen cap 15, which is snapped into place at the upper end of the waist shell 13. A hanging loop 16 is provided at the end of the pen cap 15, allowing users to easily hang the pen on bags, pockets, keychains, etc., making it convenient to carry and also providing a decorative effect. Furthermore, in this embodiment, the pen shell 11 is gourd-shaped, wider at the bottom than the top, with the maximum outer diameter of the waist shell 13 being smaller than the maximum outer diameter of the bottom shell 14. Compared to traditional "capsule" type retractable pens, it fits the curvature of the palm better when held, allowing the thumb and forefinger to rest firmly between the waist shell 13 and the bottom shell 14, facilitating grip and improving the user's stability while writing. In addition, this gourd-shaped retractable pen can be sprayed with different colors on the outer surface of its shell 11 to meet the color preferences of different users. See also Figure 9 Multiple pens of different colors can be fixed to the same "vine" by the hanging ring 16 on their pen caps 15 and packaged together for sale as a set, which has good market prospects.

[0036] Both the waist shell 13 and the bottom shell 14 adopt a detachable connection structure. The waist shell 13 includes an upper waist shell 21 and a lower waist shell 22 that are interlocked and fixed together. The bottom shell 14 includes an upper bottom shell 23 and a lower bottom shell 24 that are interlocked and fixed together. This detachable design facilitates the assembly of the pen and the replacement of the pen refill 12, improving the product's sustainability. In this embodiment, an arc-shaped notch can be opened on the lower outer edge of the upper bottom shell 23, making it convenient to insert a tool into the arc-shaped notch to pry open the lower waist shell 22.

[0037] In this embodiment, the elastic element is a compression spring 26, and the rotating element is a bearing 25. The bearing 25 is fixedly installed inside the waist shell 13. The bearing 25 is slidably sleeved with the bottom shell 14 and is also fitted with the compression spring 26. The compression spring 26 is used to push the bearing 25, along with the waist shell 13, away from the bottom shell 14. Through the elastic action of the compression spring 26, an elastic sliding connection is achieved between the waist shell 13 and the bottom shell 14, providing a power source for decompression operations such as pressing and bouncing. The dual function of the bearing 25 and the compression spring 26 is also the premise for the fun and decompression function of this utility model.

[0038] The upper waist shell 21 is provided with a mounting groove 31 that matches the outer diameter of the outer ring 34 of the bearing 25. The inner end of the lower waist shell 22 is provided with a first annular boss 32. A first limiting shoulder 33 is provided in the mounting groove 31. One end of the outer ring 34 of the bearing 25 is in close contact with the first limiting shoulder 33. After the lower waist shell 22 and the upper waist shell 21 are snapped together, the end of the first annular boss 32 is in close contact with the other end of the outer ring 34 of the bearing 25. The lower bottom shell 23 is provided with a placement cylinder 35 for accommodating the pen refill 12 and the pen tube 122. The placement cylinder 35 is provided with a guide part 36 that matches the inner diameter of the inner ring 45 of the bearing 25, allowing the bearing 25 to slide axially along the guide part 36. Through this structural design, the bearing 25 can be stably installed in the waist shell 13, providing reliable mechanical support for the elastic sliding and rotation of the waist shell 13.

[0039] One end of the placement tube 35 is provided with a lead outlet 41, and an annular groove 42 is provided on the outer periphery of the lead outlet 41. The inner side of the upper end of the waist shell 21 is provided with an annular protrusion 43 that engages with the annular groove 42, so that the lead outlet 41 of the placement tube 35 extends out relative to the upper end of the waist shell 21 and is locked in place. Through the engagement of the annular groove 42 and the annular protrusion 43, a tight connection is achieved between the placement tube 35 and the waist shell 21, so that the pen lead 12 is locked after extending out relative to the waist shell 13 to ensure normal writing.

[0040] The placement cylinder 35 is further provided with a second limiting shoulder 44, which is located at the end of the guide portion 36 away from the core portion 41. Its outer diameter is larger than the outer diameter of the compression spring 26. The compression spring 26 is sleeved on the guide portion 36 and positioned between the inner ring 45 of the bearing 25 and the second limiting shoulder 44. The second limiting shoulder 44 provides both limiting and support for the compression spring 26, ensuring stable installation and normal rebound of the compression spring 26 during operation.

[0041] The placement cylinder 35 is provided with a third limiting shoulder 46 to prevent the pen refill 12 from detaching from the refill outlet 41. One end of the pen refill 12 tube 122 contacts and is limited by the third limiting shoulder 46, allowing the pen tip 121 of the pen refill 12 to pass through while preventing the pen tube 122 from passing through. The inner end of the lower shell 24 is provided with a second annular protrusion 47. One end of the pen tube 122 of the pen refill 12 is located in the second annular protrusion 47. After the upper shell 23 and the lower shell 24 are snapped together, the inner end face of the second annular protrusion is tightly attached to one end of the pen tube 122, causing the pen tip 121 of the pen refill 12 to extend out of the refill outlet 41 end face of the placement cylinder 35. Through the dual limiting effect of the third limiting shoulder 46 and the second annular protrusion 47, the stable fixation of the pen refill 12 within the lower shell 14 is ensured.

[0042] The guide portion 36 is provided with an inner cavity 48 that is adapted to the pen tube 122 of the pen refill 12. The diameter of the inner cavity 48 gradually decreases towards the end of the pen refill portion 41, so that after the pen refill 12 is pushed in, its outer surface is pressed and fixed against the inner wall of the inner cavity 48. The pen barrel adopts a design that is pressed and fixed against the inner wall of the inner cavity 48 of the guide portion 36, which can prevent the pen refill 12 from shaking during writing, thereby improving the stability of the pen refill 12 during writing.

[0043] In this embodiment, the pen shell 11 can be made of engineering plastics (such as ABS, PC), the bearing 25 should preferably be a small deep groove ball bearing 25, and the compression spring 26 can be made of spring steel.

[0044] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
