Description

Technical Field

[0001] This utility model relates to the field of fountain pen technology, specifically to a fountain pen that can effectively prevent ink leakage. Background Technology

[0002] In existing fountain pen designs and uses, the sealing effect at the connection between the pen and the ink cartridge has always been a key concern for both users and manufacturers.

[0003] Traditional splicing methods often rely on a tight fit between the ink cartridge and the pen body to achieve a seal. However, this fit can often deteriorate due to differences in materials, insufficient manufacturing precision, or wear and tear after long-term use. If the seal is not tight, ink may seep out from the tiny gaps at the connection, causing ink leakage. This not only affects the writing experience but may also contaminate clothing, books, and other items. Utility Model Content

[0004] The purpose of this invention is to provide a fountain pen that can effectively prevent ink leakage, in order to solve the problem mentioned in the background art. Traditional splicing methods often rely on a tight fit between the ink cartridge and the pen body to achieve a seal. However, this fit often suffers from reduced sealing performance due to material differences, insufficient manufacturing precision, or wear after long-term use. Once the seal is not tight, ink may seep out from the tiny gaps at the connection, causing ink leakage. This not only affects the writing experience but may also cause pollution to clothing, books, etc.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fountain pen that can effectively prevent ink leakage, comprising a pen body, a pen nib fixedly mounted on one side of the pen body, an ink sac disposed on the other side of the pen body, an mounting ring fixedly connected to one side of the ink sac, the mounting ring being sleeved around the center of the other side of the pen body, a plurality of sealing grooves I being formed on the outer side of the other end surface of the pen body, a sealing gasket I being fixedly connected to the inner wall of the sealing groove I, an outer ring fixedly connected to one side of the outer surface of the mounting ring, and a plurality of sealing grooves II being formed on one side of the outer ring. A sealing gasket is fixedly connected to the inner wall of the sealing groove 2. Several circular protrusions are fixedly connected to one side of the mounting ring. Several circular protrusions are fixedly connected to the outer side of the other end surface of the pen body. An inner plate is fixedly connected to one side of the mounting ring. Several movable grooves are opened on the inner wall of the inner plate. A movable block is set at the bottom of the movable groove. A circular protrusion is fixedly connected to the center of the bottom of the movable block. Several sealing grooves are opened on one side of the outer surface of the pen body corresponding to one side of the mounting ring. A sealing gasket is fixedly connected to the inside of the sealing groove 3.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This fountain pen effectively prevents ink leakage by innovatively designing a three-layer sealing structure between the pen body and the ink cartridge mounting ring: sealing groove one and sealing gasket one, sealing groove two and sealing gasket two, and sealing groove three and sealing gasket three. This multi-layer sealing design ensures that even if one layer of the seal experiences minor wear due to long-term use or external force, the other layers continue to function, effectively preventing ink leakage. Circular protrusions one and two fit tightly with their corresponding sealing grooves and gaskets, further enhancing the reliability of the seal and reducing the possibility of ink seepage from the connection point. In addition to the multi-layer sealing structure, this invention also employs a threaded connection method with internal and external threads. This connection method not only… It provides a robust mechanical connection and further enhances the sealing performance of the connection through the tight engagement of the threads. At the same time, the sealing effect of the threaded connection is aided by sealing gaskets such as sealing gasket one and sealing gasket two. These sealing gaskets are made of soft and wear-resistant materials and can effectively fill the tiny gaps between the threads to prevent ink penetration. It is also designed with an internal plate and its movable groove, movable block, and circular protrusion three components. When the ink cartridge and mounting ring are installed on the pen body, the movable block can slide in the groove and automatically adjust the contact pressure between the circular protrusion three and the sealing gasket three through the elastic action of the damping rod and the return spring, thereby maintaining the tightness of the seal. This dynamic adjustment mechanism not only improves the adaptability of the seal. Attached Figure Description
