Description

Stable ink-discharging water-based pen point

Technical Field

The application relates to the technical field of water-based pens, in particular to a water-based pen point capable of stably discharging ink.

Background

Stationery products are widely available, and among them, writing pens are a kind of stationery products which are widely used, including ball-point pens, fountain pens, marking pens, fountain pens, highlighters, and the like. In a water-based pen such as a ball-point pen or a fountain pen, ink is contained in a cartridge tube, and a pen tip is attached to the front end of the cartridge tube. When writing, the ball on the pen head rolls to drive the ink to flow out, and the pen is written on the paper.

The production method of the water-based pen point is to use a solid stainless steel material to be processed and molded by multi-pass gaw. After the solid material is chamfered at the bottom, a central hole is drilled from the inside of the solid material to finish an ink channel, a ball seat is formed by cutting at a high speed at the front end and communicated with the ink channel, finally, a ball is embedded into the hole of the ball seat, and an ink guide cotton core is placed in the ink channel.

With respect to the related art in the above, the inventors consider that: when the existing water-based pen point is used for a long time, impurities in ink can be adsorbed on an ink channel, and the impurities are collided on an ink guide cotton core, so that the flowing of the ink is influenced, the ink is easy to cause unstable ink discharge, the writing is influenced, and the improvement is needed.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that the ink is unstable easily to go out in long-time use of water-based nib, this application provides a water-based nib of stable play ink.

The application provides a stabilize water-based nib that goes out china ink adopts following technical scheme:

the utility model provides a stabilize water-based nib of going out china ink, includes nib body and a pearl, the one end of nib body is provided with apical part, be provided with the mounting groove that is used for installing a pearl on the apical part, the one end that apical part was kept away from to the nib body is provided with the lock pin groove that is linked together with the mounting groove, the lock pin inslot is provided with the cotton core of first water guide, be provided with a plurality of water guide holes on the cell wall in lock pin groove, water guide hole one end and lock pin groove intercommunication, the other end and mounting groove intercommunication, be provided with the cotton core of second water guide in the water guide hole, the cotton core one end of second water guide is connected with the cotton core of first water guide.

Through adopting above-mentioned technical scheme, transmit printing ink to the mounting groove in through first water guide cotton core, the rotation of a ball in the mounting groove makes printing ink adhere to the effect of writing in order to realize on the ball surface, printing ink accessible second water guide cotton core on the first water guide cotton core transmits to the mounting groove in through the water guide hole simultaneously, the transfusion volume of printing ink has been increased, when having adsorbed impurity on the cell wall in refill groove and having made the bore reduce, the cotton core of second water guide can directly be followed first water guide and is transmitted printing ink on the cotton core, in order to realize improving the stability of china ink.
