Abstract

The utility model relates to a kind of buckle-type gel ink pen shell, and comprise shell, enclosure is provided with the cavity can placing refill of gel-ink pen, and cavity head has nib mouth, and afterbody has tail mouth; Described cavity side longitudinally has embedded groove, and described embedded groove is communicated with nib mouth and tail mouth; Described cavity is provided with annular holddown groove and annular stop flange near nib port part, this shell simplifies pen core replacement process, only pen core simply need be pressed into the replacing that can complete pen core from a shell-side face, thus enable the pen core of a shell supporting various specifications, greatly reduce the waste of a shell, the value that is used alone of pen core is improved.

Description

Buckle-type gel ink pen shell

Technical field

The utility model relates to a kind of buckle-type gel ink pen shell, belongs to field of stationery.

Background technology

Traditional pen core handling mode is comparatively complicated, and has the pen core of its correspondence due to each shell, causes when pen core run out, a shell and pen core together can be thrown away, cause the waste of resource.

Utility model content

In order to solve the problem, the utility model proposes a kind of buckle-type gel ink pen shell, which simplify pen core replacement process, only pen core simply need be pressed into the replacing that can complete pen core from a shell-side face, thus make the occupation mode of a multiple pen core of shell become possibility, greatly reduce the waste of a shell, the value that is used alone of pen core is improved.

The utility model solves the technical scheme that its technical problem adopts: a kind of buckle-type gel ink pen shell, and comprise shell, enclosure is provided with the cavity can placing refill of gel-ink pen, and cavity head has nib mouth, and afterbody has tail mouth; Described cavity side longitudinally has embedded groove, and described embedded groove is communicated with nib mouth and tail mouth; Described cavity is provided with annular holddown groove and annular stop flange near nib port part.

Described shell adopts plastic material.

The diameter of described holddown groove is greater than the internal diameter of cavity.

The cross section of described defining flange is step, and internal diameter reduces gradually from inside to outside, and the internal diameter of defining flange is all less than the internal diameter of cavity.

Described embedded groove is helically line setting centered by the axis of cavity, and this helix arranges a circle, and its anglec of rotation is not more than 360 degree, and its two ends lay respectively at nib mouth and tail mouth, so more can effectively prevent pen core from scurrying out.

Described embedded groove is positioned at the A/F at holddown groove position and the equal diameters of holddown groove.

The beneficial effects of the utility model are: a kind of buckle-type gel ink pen shell, which simplify pen core replacement process, only pen core simply need be pressed into the replacing that can complete pen core from a shell-side face, thus enable the pen core of a shell supporting various specifications, greatly reduce the waste of a shell, the value that is used alone of pen core is improved.

Fig. 3 is pen core structural representation.

In figure, 1. shell, 2. embedded groove, 3. nib mouth, 4. tail mouth, 5. cavity, 6. holddown groove, 7. defining flange, 8. pen core, 9. retainer plate.

Detailed description of the invention

In the drawings, a kind of buckle-type gel ink pen shell, comprises shell 1, and shell 1 inside is provided with the cavity 5 can placing refill of gel-ink pen, and cavity 5 head has nib mouth 3, and afterbody has tail mouth 4; Described cavity 5 lateral longitudinal is to having embedded groove 2, and described embedded groove 2 is communicated with nib mouth 3 and tail mouth 4; Described cavity 5 is provided with annular holddown groove 6 and annular stop flange 7 near nib mouth 3 position.

Described shell 1 adopts plastic material.

The diameter of described holddown groove 6 is greater than the internal diameter of cavity 5.

The cross section of described defining flange 7 is step, and its internal diameter reduces from inside to outside gradually, and the internal diameter of defining flange 7 is all less than the internal diameter of cavity 5.

Described embedded groove 2 is helically line setting centered by the axis of cavity 5, and this helix arranges a circle, and its anglec of rotation is not more than 360 degree, and its two ends lay respectively at nib mouth 3 and tail mouth 4, so more can effectively prevent pen core 8 from scurrying out.

Described embedded groove 2 is positioned at the A/F at holddown groove 6 position and the equal diameters of holddown groove 6.

During use, pen core 8 is pressed in cavity 5 from embedded groove 2, ensures that the retainer plate 9 of pen core 8 embeds the replacing that holddown groove 6 completes pen core 8, thus enables the pen core 8 of a shell supporting various specifications, greatly reduce the waste of a shell.
