Description

A non-forked pen nib

technical field

The utility model relates to the field of fountain pens; in particular, it relates to a non-branched fountain pen tip.

Background technique

Fountain pen is a writing instrument commonly used by people. The nib is made of metal. It is smooth and elastic when writing, and it is quite smooth. The pen contains ink through the hollow pen tube, and then writes through the nib through gravity and capillary action. For all the most commonly used dark nib fountain pens and bright nib fountain pens, the ink guide groove at the front end of the nib is cut through by cutting, as shown in Figure 1. Not only is the manufacturing process cumbersome, but also long-term use or a little forceful use will cause the nib to fork, the amount of ink to be injected will increase, and the writing strokes will become thicker.

Utility model content

The purpose of the utility model is to provide a fountain pen nib that does not bifurcate in order to solve the problems in the prior art in the above-mentioned background technology.

The technical solution adopted by the utility model to solve the technical problem is: a non-branched steel pen tip, including a nib body, a writing groove and a nib ball head, the nib ball head is provided with a writing groove, and the lower end of the nib body A ball head is provided, and the feature is that: the lower surface of the nib body is provided with an ink guide groove corresponding to the position of the flow guide groove; the ink guide groove extends to the ball head and communicates with the writing groove.

Preferably: it also includes an ink storage tank, the ink storage tank is arranged on the upper surface of the nib body, and it is connected to the writing slot.

Preferably: the ink guide groove gradually narrows from the middle to both ends.

Preferably: the widest part of the ink guiding groove deviates from the center of the ink guiding groove and is close to the end connected to the writing groove.

Preferably: the widest part of the ink guide groove is located at the front end of the feed.

Preferably: the cross section of the writing groove is an inverted isosceles trapezoid.

Preferably: the nib body is made of rigid metal.

Preferably: both axial ends of the nib body are bent downward to form a radian.

Preferably: the nib body is integrally formed by stamping.

Preferably: the nib body covers the upper surface of the feed

Compared with the prior art, the utility model has the following beneficial effects:

The ink guiding groove of the utility model adopts a stamping method to be formed at one time, which saves the cutting process and makes the technological process simpler. Moreover, the ink guide groove is a punched groove, and the through groove is cut, even if it is written hard or used for a long time, it will not cause the nib to split, ensuring the quality and fluency of writing, and avoiding wasting ink.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

1. As shown in Figures 2 to 8, a non-forked steel nib includes a nib body 2, a writing groove 31 and a nib ball 3, the nib ball 3 is provided with a writing groove 31, and the nib body 2 The lower end is provided with a ball head 3, and it is characterized in that: the lower surface of the nib body 2 is provided with an ink guide groove 21, and the ink guide groove 21 corresponds to the position of the flow guide groove 11; the ink guide groove 21 extends To the ball head 3 and communicate with the writing groove 31. Compared with the traditional pen tip, the ink guide groove 21 is changed into a groove instead of a cut-through groove. Even if it is written vigorously and used for a long time, it will not fork, avoiding thicker strokes and poor writing caused by the fork of the traditional pen tip. Smooth while avoiding wasted ink.

As shown in FIG. 9 and FIG. 10 , an ink storage tank 4 is also included, and the ink storage tank 4 is arranged on the upper surface of the nib body 2 and communicated with the writing groove 31 . After the ink flows into the writing tank 31, in order to prevent the ink from flowing too much and causing the strokes to be too thick, the ink is partially stored in the ink storage tank 4 by capillary phenomenon.

As shown in FIG. 3 , FIG. 7 , and FIG. 8 , the ink guide groove 21 gradually narrows from the middle to both ends. The widest part of the ink guiding groove 21 deviates from the center of the ink guiding groove 21 and is close to the end connected to the writing groove 31 . The widest part of the ink guide groove 21 is located at the front end of the feed 1 . The widest part of the ink guide groove 21 is used to store enough ink, which is continuously supplied to the writing groove, so as to prevent interruption of writing due to untimely ink supply.

As shown in FIG. 8 and FIG. 10 : the cross section of the writing groove 31 is an inverted isosceles trapezoid. It is convenient for ink circulation and convenient for ink spit, which is good for writing.

As shown in FIG. 11 : the nib body 2 is made of rigid metal. The two axial ends of the nib body 2 are bent downward to form a radian. When writing forcefully, the nib body 2 is deformed under pressure, which affects the deformation of the writing groove, making the writing strokes thicker. When writing lightly, the strokes maintain the original fineness.

The nib body 2 is integrally stamped and formed, which eliminates the need for separate cutting of the ink guide groove in the traditional production process, making the production process simpler and more efficient.

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
