Description

nib of a neutral pen

technical field

The utility model belongs to the field of stationery, in particular to a nib for gel pens.

Background technique

Pens used for writing can be divided into three categories in modern times: pencils, fountain pens and gel pens. The scope of application of pencils is now mainly concentrated in the use of primary school students and some specific needs; the scope of use of pens is wider and can basically be used It can be used in various fields of writing, but the pen also has the insurmountable defect that it needs to replenish ink, especially in the case of the impact of the popularization of computers on writing, the shortcomings of the pen in the fields of offices or enterprises are even more obvious. In order to overcome the defects of fountain pens, gel pens have been developed and applied and quickly popularized. Gel pens have the advantages of convenient writing, long-lasting handwriting, and concentrated ink.

However, gel pens also have certain defects, which are the defects that the nib of the gel pen is easy to leak ink and the ink of the nib is not solidified for a long time. The gap between the nib and the ball at the tip of the pen is realized. When the user is not using it, the ink on the nib and the ball still exists, so that the ink will overflow or after a long period of use, the ink at the nib and the ball will be due to Close to the air and dry to block the entire pen, so that the entire pen is scrapped.

Utility model content

The purpose of the utility model is to improve the existing gel pen technology, so that the gel pen can provide ink according to the user's needs, and prevent the ink from leaking or drying.

The utility model is achieved through the following technical solutions:

A nib of a neutral pen, including a fixed tube and a nib, the fixed tube and the nib are integrated, the tip of the pen is provided with a cavity, the cavity is provided with a ball, and the ball part is exposed Outside the cavity, there is a hole at the bottom of the cavity that communicates with the fixed tube and the nib. The hole at the bottom of the cavity is surrounded by an ink delivery hole that communicates with the cavity and the nib. A spring is arranged inside the fixed tube and the nib. A spring pushes against the ball through a hole in the bottom of the cavity.

As a further improvement, the inner diameter of the fixing tube is larger than the inner diameter of the pen tip and larger than the diameter of the hole at the bottom of the cavity.

There are 3-5 ink delivery holes.

The cavity is a cylindrical inner cavity wall.

There are inward protruding grooves on the same cross-section on the fixing pipe.

The beneficial effects of the utility model are:

The ball is pressed against the ball by the provided spring so that the ball and the tip of the pen form a sealed structure, which ensures that the ink cannot overflow and can also ensure that air does not enter the tip of the pen to prevent the ink from drying.

Detailed ways

Embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings. In the examples of the embodiments, the same or similar symbols throughout represent the same or similar components or components with the same or similar functions. The embodiments described below are exemplary, and are only used to explain the patent, and cannot be construed as limiting the patent.

With reference to Fig. 1 and shown in Fig. 2, a kind of nib of neutral pen comprises fixed pipe 11 and nib 12, and described nib is the structure with cavity 17, and described fixed pipe 11 and nib 12 are integrally arranged, and described A cavity 13 is provided at the end of the nib 12, and a ball 14 is arranged in the cavity 13, and a part of the ball 14 is exposed outside the cavity 13, and a hole 15 at the bottom of the cavity communicates with the fixed tube 11 and the nib 12 , the inner diameter of the fixed tube 11 is larger than the inner diameter of the nib 12 and larger than the diameter of the hole 15 at the bottom of the cavity, and the hole 15 at the bottom of the cavity is surrounded by ink delivery holes (22, 23, 24, 25) connecting the cavity 13 and the nib 12 , the number of ink delivery holes is 3-5, and the optimal choice is 3 holes, so that the ink of the pen can be supplied to the nib through the hole at the bottom of the cavity to pass through the spring, and can also be provided through an additional ink delivery hole. Holes to increase ink supply to ensure smooth writing. The fixed tube 11 and the nib 12 are provided with a spring 16, and the spring 16 passes through the hole 15 at the bottom of the cavity to press the ball 14.

The cavity 13 in this embodiment is a cylindrical cavity wall, and cavities with other shapes can be selected in other embodiments.

There is an inwardly protruding groove 18 located on the same cross section on the fixing tube, and the inwardly protruding part is used to fix the other end of the spring 16. In other embodiments of the utility model, other fixing methods can also be selected for fixing. Spring, but the process of processing inwardly protruding grooves is the easiest.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be considered within the scope of protection of this patent.
