Description

Technical Field

[0001] This utility model relates to the field of injection-type ink-absorbing two-color fountain pens, and more specifically, to an injection-type ink-absorbing two-color fountain pen. Background Technology

[0002] Currently, in the traditional technology, when filling fountain pens sold on the market with ink, the pen tip must be unscrewed, the ink cartridge must be pinched with fingers to squeeze out the air, the ink cartridge must be immersed in ink, and then the fingers pinched on the ink cartridge must be released to allow the ink cartridge to absorb the ink. This method of filling ink can easily get your hands dirty, is time-consuming, and fountain pens can only absorb one type of ink, which is very inconvenient.

[0003] In existing technology, such as the utility model patent announcement number CN2666681Y, a two-color ink-filling fountain pen is disclosed. It features a pen tip and nib at each end, and its central cylinder is symmetrically divided into two parts, each connected to a pen tip. An ink inlet and a cap are provided at the connection point between the central cylinder and each pen tip, essentially connecting the ends of two ink-filling pens together. The central cylinder is designed to be fully or partially transparent, allowing the user to observe the ink level and fill it in advance, preventing ink shortages during writing. This pen is simple and hygienic to fill with ink, and can store two different colors of ink simultaneously, providing great convenience to the user.

[0004] In the aforementioned patent, ink is injected from both sides, which results in poor sealing during use, blockage at the ends affecting grip, and the one-piece structure makes the manufacturing process complex, costly, and non-replaceable. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an injection-type ink-absorbing dual-color fountain pen, which adopts a two-half splicing installation structure. The pen can be disassembled into two parts, each with ink injected into its end face, and then they are inserted and fixed together. The injection end is not exposed, ensuring high sealing performance. It can be produced independently, with a simple assembly process and easy replacement.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0012] Furthermore, a pull block is fixedly connected to the outer end face of the card block, and the pull block adopts a circular block structure.

[0013] Furthermore, both the first and second pen shells are hollow semi-circular plastic shell structures.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) The pen adopts a two-half splicing installation structure, which can be separated into two parts. The ink is injected into the end face and then they are plugged into each other for fixation. The injection end is not exposed, the sealing is high, and it can be produced independently. The assembly process is simple and easy to replace. Attached Figure Description
