Description

Nested gel ink pen

Technical Field

The invention relates to the technical field of gel-ink pens, in particular to a nested gel-ink pen.

Background

The pen is an indispensable tool in daily life, work and study of people, especially, the daily pen consumption of students in school and study is quite large, and the gel ink pen is mainly used, but the existing gel ink pen needs to be replaced by the pen cap firstly, the pen cap is replaced by the pen core, and then the pen cap is screwed on, so that the steps are relatively complicated, the core replacing time is long, the screwed pen cap is easy to lose in the core replacing process, the gel ink pen cannot be continuously used, and the gel ink pen is very unfavorable for the students in the examination process.

Disclosure of Invention

The invention aims to provide a quick refill-changing type gel ink pen to solve the problems in the background technology.

In order to achieve the purpose, the technical scheme of the invention is as follows: a nested gel pen comprises a pen holder and a pen core, wherein the pen core further comprises a pen point and a connecting part, and the connecting part is a circular ring protrusion with the diameter larger than that of the pen core; the pen holder on be equipped with and inlay the groove, inlay the groove and be close to the position of nib one side and be equipped with the use spacing groove of holding a pen, be close to the position of tail one side and be equipped with and accomodate the spacing groove.

Furthermore, the embedded groove on the penholder is also provided with a fastening plug strip, and the penholder is integrally formed by adopting plastic or metal materials.

Furthermore, the fastening plug strip is mutually nested and matched with the embedding groove; the upper surface of the fastening plug strip is matched with the outer circular arc of the penholder; the lower part of the fastening plug strip is provided with an arc groove which is matched with the arc surface of the refill; the position that the fastening stuff is close to nib one side is equipped with the recess, and the position that is close to tail one side is equipped with and accomodates the recess.

Furthermore, the fastening plug strip is made of plastic or rubber or metal materials.

The pen body structure is designed in an integrated mode, the pen core is easily embedded into the embedding groove through the embedding groove arranged on one side of the pen holder to be used, the pen core is reversely embedded into the embedding groove after the pen core is used, the pen core tip can be effectively protected from being damaged, the pen core is replaced quickly and conveniently, time and labor are saved, and the pen body structure is easy to popularize and use.

In the figure: 1. the pen holder 2 comprises a storage limiting groove 3, an embedding groove 4, a limiting groove 5, a pen core 6, a connecting part 7, a pen point 8, a fastening plug strip 801, an arc groove 802, a groove 803 and a storage groove.

Detailed Description

In order to facilitate understanding of those skilled in the art, the embodiments of the present invention will be further described with reference to the accompanying drawings.

Example one

The nested gel-ink pen shown in the attached figures 1-4 comprises a pen holder 1 and a pen core 5, wherein the pen core 5 further comprises a pen point 7 and a connecting part 6, and the connecting part 6 is a circular ring protrusion with the diameter larger than that of the pen core; the pen holder 1 is integrally formed by plastic or metal materials, the pen holder 1 is provided with an embedding groove 3, a position, close to one side of the pen point, of the embedding groove 3 is provided with a limiting groove 4 for holding the pen, and a position, close to one side of the pen tail, of the embedding groove 3 is provided with a storage limiting groove 2.

When the pen is used, the pen core 5 is embedded along the embedding groove 3 on the pen holder 1, so that the connecting part 6 on the pen core 5 is limited in the groove 802, and then the pen holder 1 is provided with the embedding groove 3, and one side of the pen core is opposite to a user, so that the pen can be normally used. After using, the user can take off the refill 5 along inlaying the groove 3 through 7 one ends of nib, then reverse with the connecting portion 6 embedding on the refill 5 accomodate spacing groove 2 can.

Example two

The second embodiment is different from the first embodiment only in that a fastening plug strip 8 shown in figures 5-6 is arranged on the barrel 1 and is mutually nested and matched with the embedding groove 3, and the fastening plug strip 8 is made of plastic or rubber or metal materials; the fastening filler strip 8 is matched with the embedding groove 3; the upper surface of the fastening plug strip 8 is matched with the outer circular arc of the penholder 1; the lower part of the fastening plug strip 8 is provided with an arc groove 801, and the arc groove 801 is matched with the arc surface of the pen core 5; the fastening stopper 8 is provided with a groove 802 at a position close to the pen point, and a storage groove 803 at a position close to the pen tail.

When the pen is used, after the pen core 6 is embedded into the embedding groove 3 on the pen holder 1, the fastening filling strip 8 is embedded along the embedding groove 3, so that the pen core and the pen holder 1 form a complete arc columnar pen holder, the use is more convenient, and the use stability of the pen core 6 is further improved.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
