Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation pen technology, specifically a magnetic levitation rotary pen. Background Technology

[0002] With the continuous innovation and progress of writing tools, and the constant pursuit of user experience, innovative writing tools such as magnetic pens have gradually emerged. They use magnetic levitation technology to achieve the levitation or rotation of the pen tip, in order to meet people's requirements for pen decoration and user experience in addition to writing. The pen core of magnetic pens mainly uses gel pen.

[0003] However, for fountain pen enthusiasts, fountain pens are heavier than ballpoint pens. Therefore, if existing magnetic levitation technology is used, the weight of the fountain pen will increase the friction of rotation, resulting in insufficient levitation stability and unsatisfactory rotation effect. Therefore, this utility model provides a magnetic levitation rotating wheel fountain pen. Utility Model Content

[0004] The purpose of this invention is to provide a magnetically levitated rotating pen to solve the problem of unsatisfactory levitation and rotation effects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A magnetic levitation rotary pen includes a pen barrel, a pen cap, a writing refill, and a rotating assembly; one end of the pen barrel is threadedly connected to the pen cap and forms a cavity inside, with the writing refill housed within the cavity; the other end of the pen barrel is threadedly connected to the rotating assembly. The inner wall of the pen cap also has a magnetic ring compartment, and a magnetic ring is placed inside the magnetic ring compartment; The rotating assembly includes a rotating wheel, a bearing, and a support. The support is threadedly connected to the pen cap, the bearing is fitted onto the outer wall of the support, and the rotating wheel is threadedly connected to the outer wall of the bearing. The support includes a supporting rotating wheel, an elastic element, and a bolt. A through hole is provided inside the supporting rotating wheel, and the elastic element is disposed within the through hole. One end of the through hole is threadedly connected to the bolt, and the diameter of the other end is reduced to limit the range of the elastic element's protrusion, so that the end of the elastic element cannot be completely exposed outside the through hole. The surface of the elastic element's end is smooth, providing support for the rotation of the support and reducing rotational resistance.

[0006] The elastic element includes at least one iron ball and a spring; one end of the spring abuts against the bolt, and the other end abuts against the iron ball, so that the iron ball extends out of the through hole as an elastic element; the diameter of the other end of the through hole is smaller than the maximum diameter of the iron ball, so that part of the iron ball protrudes out of the through hole.

[0007] Preferably, the outer wall of the support wheel extends outward from the end away from the pen cap to form a step; the outer wall of the other end of the support wheel is threadedly connected to the inner wall of the pen cap; the bearing is sleeved between the step and the end of the pen cap, and the outer wall diameter of the bearing is larger than the outer wall diameter of the outwardly extending support wheel, so that a rotation groove is formed between the step and the bearing.

[0008] Preferably, the rotating wheel is rotatably connected to the outer wall of the bearing, the rotating wheel has an L-shaped cross-section, and the vertical part of the rotating wheel's cross-section is embedded in the rotating groove; a bearing top cover is fixedly connected to the end of the bearing away from the step, the outer wall of the bearing top cover is threadedly connected to the inner wall of the transverse part of the rotating wheel's cross-section, and the inner diameter of the bearing top cover is larger than the outer diameter of the pen cap end.

[0009] Preferably, the pen refill includes a writing section and an ink supply section. The writing section includes a pen tip and a pen body. The pen tip is fixedly connected to one end of the pen body, and the ink supply section is inserted into the other end of the pen body to provide ink to the pen tip.

[0010] Preferably, the pen barrel includes a grip, a tail rod, and a tail cap; one end of the grip is threadedly connected to the tail cap, and the other end is detachably connected to the outer wall of the pen body near the ink supply part; one end of the tail rod is threadedly connected to the tail cap, and the other end is detachably connected to the outer wall of the pen body near the ink supply part.

[0011] Preferably, a push-button is provided between the pen cap and the writing part. The push-button is fitted outside the writing part and its end extends beyond the pen tip. The outer wall of the push-button is detachably connected to the inner wall of the pen grip.

[0012] Preferably, the magnetic ring compartment is located at the end of the pen cap near the pen grip, and when the pen cap is connected to the pen grip, the movement of the magnetic ring is restricted by the end of the pen grip.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The suspension and rotation stability is enhanced by setting iron balls to greatly reduce the contact area and friction, allowing it to withstand greater weight. The outward force of the spring on the iron balls allows them to remain in contact with the end of the support rod for a longer period, resulting in a longer duration of suspension and rotation of the pen and smoother rotation.

[0014] It is easy to assemble and disassemble, and each component is connected by a threaded detachable connection, which facilitates later maintenance or component replacement.

[0015] It is not easy to lose. When using a fountain pen, the cap and rotating part can be suspended and placed, so that the cap can be quickly found after use. Attached Figure Description

[0018] Example 1:

[0019] Please see Figures 1-7 This utility model provides a technical solution: a magnetic levitation rotary pen, including a pen barrel 1, a pen cap 2, a pen core 3 and a rotating assembly 4; one end of the pen barrel 1 is threadedly connected to the pen cap 2 and forms a cavity inside, and the pen core 3 is built into the cavity; the other end of the pen barrel 1 is threadedly connected to the rotating assembly 4; The inner wall of the pen cap 2 is also provided with a magnetic ring compartment 21, and a magnetic ring 22 is provided inside the magnetic ring compartment 21.

[0020] The rotating assembly 4 includes a rotating wheel 41, a bearing 42, and a support 43. The support 43 is threadedly connected to the pen cap 2, the bearing 42 is fitted onto the outer wall of the support 43, and the rotating wheel 41 is threadedly connected to the outer wall of the bearing 42. The support 43 includes a supporting rotating wheel 431, at least one iron ball 432, a spring 433, and a bolt 434. The supporting rotating wheel 431 has a through hole inside, one end of which is threadedly connected to the bolt 434, and the other end has a smaller diameter, slightly smaller than the iron ball 432. The spring 433 and the iron ball 432 are both disposed within the through hole, with one end of the spring 433 abutting against the bolt 434 and the other end abutting against the iron ball 432. The diameter of the iron ball 432 is slightly smaller than the end of the through hole, allowing part of the iron ball 432 to protrude outside the through hole. The spring 433 is a compression spring. The iron ball 432 and the spring 433 constitute an elastic element.

[0021] The outer wall of the supporting wheel 431, at the end furthest from the pen cap 2, extends outward to form a step 4311; the outer wall of the other end of the supporting wheel 431 is threadedly connected to the inner wall of the pen cap 2; a bearing 42 is fitted between the step 4311 and the end of the pen cap 2, and the outer diameter of the bearing 42 is larger than the outer diameter of the outwardly extending outer wall of the supporting wheel 431, thus forming a rotation groove between the step 4311 and the bearing 42; the wheel 41 is rotatably connected to the outer wall of the bearing 42, and the cross-section of the wheel 41 is L-shaped, with the vertical portion of the cross-section of the wheel 41 embedded in the rotation groove; a bearing top cover 421 is fixedly connected to the end of the bearing 42 furthest from the step 4311, and the outer wall of the bearing top cover 421 is threadedly connected to the inner wall of the transverse portion of the cross-section of the wheel 41, and the inner diameter of the bearing top cover 421 is larger than the outer diameter of the pen cap 2. The outer wall of the wheel 41 can be designed with different shapes or different fonts to improve its aesthetics; when holding the pen, the wheel 41 can be rotated quickly and for a long time with the thumb to increase its fun.

[0022] The pen refill 3 includes a writing section 31 and an ink supply section 32. The writing section 31 includes a pen tip 311 and a pen body 312. The pen tip 311 is fixedly connected to one end of the pen body 312, and the ink supply section 32 is inserted into the other end of the pen body 312 to provide ink to the pen tip 311. The ink supply section 32 is a fountain pen ink converter, or it can be a disposable ink cartridge. The disposable ink cartridge is quick to replace and convenient to use.

[0023] The pen barrel 1 includes a grip 11, a tail rod 12, and a tail cap 13; one end of the grip 11 is threadedly connected to the pen cap 2, and the other end is detachably connected to the outer wall of the pen body 312 near the ink supply part 32, such as by snap-fit ​​connection or threaded connection. The grip 11 is a part used for hand gripping when writing; one end of the tail rod 12 is threadedly connected to the tail cap 13, and the other end is detachably connected to the outer wall of the pen body 312 near the ink supply part 32, such as by snap-fit ​​connection or threaded connection.

[0024] A push-button 34 is provided between the pen cap 2 and the writing part 31. The push-button 34 is fitted outside the writing part 31 and its end extends beyond the pen tip 311. The outer wall of the push-button 34 is detachably connected to the outer wall of the pen body 312, such as by snap-fit ​​connection, to protect the pen tip 311.

[0025] The magnetic ring compartment 21 is located at the end of the pen cap 2 near the pen grip 11. When the pen cap 2 is connected to the pen grip 11, the magnetic ring 22 is restricted from moving by the end of the pen grip 11, and it is also used to quickly determine the position of the magnetic ring 22.

[0026] To achieve the levitation effect, this application also includes a base 5, on which a supporting semi-ring 51 is fixedly connected. The protruding surface of the supporting semi-ring 51 is connected to the base 5, and the two ends of the supporting semi-ring 51 are tilted. A ring magnet 53 is fixedly connected to the higher end of the supporting semi-ring 51, and the ring magnet 53 has an opening at the top. A supporting rod 52 is fixedly connected to the lower end of the supporting semi-ring 51, and the supporting rod 52 faces the middle of the ring magnet 53.

[0027] Working principle: Suspension principle: The operator tilts the pen and places the pen cap 2, where the magnetic ring 22 is located, in the middle of the ring magnet. Then, the iron ball 432 at the end contacts the end of the support rod 52. The magnetic ring 22 and the ring magnet 53 form a repulsive field. The magnetic ring 22 and the ring magnet repel each other, so that the pen is suspended in the middle of the ring magnet 53.

[0028] Suspension and rotation principle: Since the iron ball 432 contacts the end of the support rod 52 with only a very small contact area, the friction can be greatly reduced. After the operator rotates the pen, the support wheel 431 and the iron ball 432 will rotate accordingly. Due to the outward force of the spring 433 on the iron ball 432, the iron ball 432 can contact the end of the support rod 52 for a longer time, thus making the suspension and rotation time longer.
