Description

Technical Field

[0001] This utility model relates to the field of fountain pens, and in particular to a rotary tip-extruding, sealed fountain pen that prevents ink from drying out. Background Technology

[0002] A fountain pen is a classic writing instrument, favored for its elegant design and smooth writing experience. The nib is usually made of metal and draws in ink through capillary action, producing clear and expressive lines when writing. It is suitable for signing, practicing calligraphy, or daily note-taking. Whether it is an exquisite gold-plated body or a simple modern design, a fountain pen is not only a practical tool, but also a reflection of the user's taste and style.

[0003] Currently, most traditional fountain pens on the market use a cap design, which requires removing the cap to write. However, this structure has obvious drawbacks. When the pen is idle for a long time, the nib exposed to the air is prone to ink drying and congealing, which can clog the ink flow channel and seriously affect the smoothness of writing. At the same time, existing fountain pen technology has not effectively solved the contradiction between preventing the nib from drying out and convenient use. In particular, there is a technological gap in achieving nib extension while maintaining a sealed design to prevent ink from drying out. Therefore, there is an urgent need to develop a fountain pen with an innovative structure that can achieve rapid extension and retraction of the nib through a rotating mechanism, and ensure a completely sealed protective environment for the nib when stored. This would fundamentally solve the two major pain points of ink drying out and cap loss, and improve the practicality and user experience of the fountain pen. Utility Model Content

[0004] The purpose of this invention is to provide a rotary tip-extruding, sealed, ink-preventing fountain pen, which solves the problem that existing fountain pen technology has not effectively resolved the contradiction between preventing the pen tip from drying out and facilitating use.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A rotating tip sealed anti-drying ink fountain pen, characterized in that it comprises: an upper shell, a rotating shell rotatably mounted on the upper shell, a lower shell threaded onto the lower shell, a pressure rod rotatably mounted inside the rotating shell, an annular groove being carved inside the rotating shell, a locking block being fixedly mounted on the pressure rod, the locking block matching the annular groove, and a sealing gasket being fixedly mounted inside the lower shell, the sealing gasket having a cut in the middle portion.

[0007] The upper and lower shells protect the internal structure from dust and impurities, while providing mechanical strength and an aesthetically pleasing appearance. The rotating shell facilitates user operation, allowing for easy adjustment or manipulation of internal components, increasing the device's flexibility and functionality. The pressure rod applies pressure to operate or activate internal mechanisms, ensuring proper functioning. The annular groove secures or positions internal components, ensuring their correct placement and preventing loosening or displacement. The locking blocks lock or fix components within the annular groove, preventing movement or detachment during operation and improving reliability. The sealing gasket effectively prevents the pen tip from drying out, providing excellent airtightness and protecting it from external environmental influences.

[0008] As an improvement, multiple slide bars are fixedly installed inside the upper shell, and the pressure rod is slidably installed on the slide bars.

[0009] The slider design provides a smooth sliding surface, facilitating the sliding action of the pressure rod and thus improving the smoothness and accuracy of operation.

[0010] As an improvement, an ink sac is provided under the pressure rod, and a circular groove matching the ink sac is carved inside the pressure rod.

[0011] Ink cartridges are designed to store ink or similar substances for writing or other applications that require ink, ensuring a continuous supply.

[0012] As an improvement, a pen tip is installed under the ink sac, a spring is provided on the outer sleeve of the pen tip, a decorative block is fixedly installed on the pressure rod, and a protective pad is provided on the outer sleeve of the lower shell.

[0013] The pen tip is designed for writing or marking, directly contacting paper or other surfaces to achieve the writing function. The tip is also enclosed by the feed, reducing contact with air and slowing ink evaporation. A spring provides elasticity to reset the pen tip, ensuring proper function and ease of operation. Decorative blocks enhance visibility and aesthetics. Protective pads facilitate sliding and reduce friction between the user and the lower casing, offering some protection for the user's fingers.

[0014] As an improvement, the upper part of the rotating shell is made of transparent material, and the sealing gasket is made of soft silicone.

[0015] The beneficial effects of this utility model are as follows: By innovating the fountain pen, the nib can be quickly extended and retracted through a rotating mechanism, forming a completely sealed protective environment when stored, effectively isolating air and fundamentally solving the problems of ink drying and condensation and ink flow channel blockage. This significantly improves the smoothness of writing. At the same time, it abandons the traditional pen cap design, avoiding the pain point of losing the pen cap, and achieves quick pen extension through the rotating mechanism. While ensuring airtightness, it perfectly balances anti-drying and convenience, greatly optimizing the user experience and the practicality of the fountain pen. Attached Figure Description

[0021] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figures 1 to 4As shown, a rotating tip-extruding, sealed, ink-preventing fountain pen is characterized by comprising: an upper shell 1, a rotating shell 2 rotatably mounted on the upper shell 1, a lower shell 3 threadedly mounted on the lower shell 1, a pressure rod 4 rotatably mounted inside the rotating shell 2, an annular groove 5 carved inside the rotating shell 2, a locking block 6 fixedly mounted on the pressure rod 4, the locking block 6 matching the annular groove 5, and a sealing gasket 7 fixedly mounted inside the lower shell 3, the sealing gasket 7 having a notch carved in the middle. The upper shell 1 and lower shell 3 facilitate protection of the internal structure, preventing dust and impurities from entering, while providing mechanical strength and an aesthetically pleasing appearance. The rotating shell 2 facilitates user rotation, thus allowing users to easily adjust or operate internal components, increasing the flexibility and functionality of the device. The pressure rod 4 helps apply pressure to operate or activate the internal mechanism, ensuring the normal operation of the device. The annular groove 5 is used to fix or position the internal components, ensuring the correct position of each part inside the device and preventing loosening or displacement. The locking block 6 is used to lock or fix the pen tip 10 in the annular groove 5, thereby preventing it from moving or falling off during operation and improving the reliability of the equipment. The sealing gasket 7 effectively prevents the pen tip 10 from drying out, thus providing good airtightness and protecting the pen tip 10 from the influence of the external environment.

[0023] like Figures 1 to 4 As shown, multiple sliders 8 are fixedly installed inside the upper shell 1, and the pressure rod 4 is slidably installed on the sliders 8. The sliders 8 provide a smooth sliding surface, facilitating the sliding action of the pressure rod 4 and improving the smoothness and accuracy of operation. An ink sac 9 is located below the pressure rod 4, with a circular groove inside the pressure rod 4 matching the ink sac 9. The ink sac 9 stores ink or similar substances for writing or other applications requiring ink, ensuring a continuous supply. A pen tip 10 is installed below the ink sac 9, and a spring 11 is fitted over the pen tip 10. A decorative block 12 is fixedly installed on the pressure rod 4, and a protective pad 13 is fitted over the lower shell 3. The pen tip 10 is used for writing or marking, directly contacting paper or other surfaces to achieve the writing function. Simultaneously, the pen tip 10 is encased by the feed, reducing contact with air and slowing ink evaporation. The spring 11 provides elastic force to reset the pen tip 10, ensuring normal function and ease of operation. The decorative block 12 facilitates observation for the user and enhances aesthetics. The protective pad 13 facilitates sliding while reducing friction between the user and the lower shell 3, providing some protection for the user's fingers. The upper part of the rotating shell 2 is made of transparent material, and the sealing gasket 7 is made of soft silicone.

[0024] During use, first hold the upper shell 1 of the pen, then rotate the rotating shell 2 clockwise. At this time, the pressure rod 4 will slide and move downward inside the rotating shell 2. As the pressure rod 4 moves downward, the locking block 6 will cooperate with the annular groove 5 to fix the position of the pressure rod 4 and prevent it from moving or coming loose during operation. During the movement, the pressure rod 4 will slide on the slider 8, which will push the ink sac 9 to drive the pen tip 10 out of the lower shell 3. The ink in the ink sac 9 will flow out through the pen tip 10 for writing.

[0025] Because the sealing gasket 7 is made of soft silicone, when the pen tip 10 is pushed, it will squeeze the sealing gasket 7, and the pen tip 10 will protrude from the cut in the sealing gasket 7 and extend out of the lower shell 3 (that is, the pen tip 10 is rotated out and protrudes into the cut of the sealing gasket 7). When the pen tip 10 is rotated back, the pen tip 10 will retract into the sealing gasket 7, so the cut of the sealing gasket 7 will spring back to a sealed state, thus the sealing gasket 7 can effectively prevent the ink from drying out. At the same time, the lower shell 3 is covered with a sliding strip 8, which reduces the friction between the user and the lower shell 3 and protects the user's fingers. After writing, the rotating shell 2 is rotated in the opposite direction, and the pressure rod 4 is reset under the action of the spring 11, so that the pen tip 10 is retracted. The whole process is simple and smooth, and the structure is reasonably designed. It not only ensures the writing quality, but also forms a completely sealed protective environment when the pen tip 10 is stored, effectively isolating air and fundamentally solving the problems of ink drying and condensation and ink channel blockage.

[0026] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
