Abstract

The utility model discloses a refill fixer, including a plurality of fixed loops, connect through the connecting rod between per two fixed loops, be equipped with the opening that can break off the fixed loop on the fixed loop, the inner wall surface and the outer wall surface of fixed loop all are equipped with protruding, the lateral wall of connecting rod also is equipped with protruding on the surface, but suit refill in the fixed loop, protruding piece can increase the frictional force of refill and fixed loop contact department, and on fixed loop outer wall and the connecting rod protruding can increase with the frictional force of pen -holder contact department to make the refill pack into when using in the pen -holder, do not produce rock let write more smooth smooth.

Description

Pen core holder

Technical field

This utility model belongs to cultural goods technical field, is specifically related to a kind of pen core holder for fixing pen core.

Background technology

At present writing in use people, ball pen and gel ink pen have become as the writing implement that people are important, it addition, along with gel ink pen becomes China's regulation special pen for examination, gel ink pen develops into main pen kind with unobstructed advantage out of ink easy to use. Existing gel ink pen is mainly made up of penholder, the cap for brush, nib and pen core, and penholder, the cap for brush are ground by injection molding, stainless steel punching press, rustless steel manufactures three kinds of production methods; Nib is divided into cannonball type and needle tube type two kinds, is respectively adopted copper alloy, rustless steel or engineering plastics and makes; The materials such as ball many employings rustless steel on pen core, hard alloy or aluminium oxide are made, and wherein, middle person's handwriting ball diameter is 0.7 millimeter, and thin person's handwriting ball diameter is 0.5 millimeter.

Inventor of the present utility model finds through research, in current gel ink pen use procedure, owing to penholder model, brand are varied, and the specification of pen core differs, if buying the pen core with penholder same brand and model to change, buy pen core very inconvenient, and if buy the pen core of popular model and change and use because can not mate with penholder completely, pen core can not coincide fixing in penholder, when writing, pen core easily rocks in penholder and collides penholder, affects writing effect.

Utility model content

The pen core when writing existed for prior art easily rocks collision penholder in penholder, affects the technical problem of writing effect, and this utility model provides a kind of pen core holder.

To achieve these goals, this utility model adopts the following technical scheme that

A kind of pen core holder, including multiple retainer ring, being connected by connecting rod between each two retainer ring, described retainer ring is provided with the opening that can disconnect retainer ring, the inner wall surface of described retainer ring and outer wall surface are equipped with protrusion, and the sidewall surfaces of described connecting rod also is provided with protrusion.

Further, the internal diameter of described retainer ring is 5mm��7mm.

Further, described protrusion has multiple, and all arranges in the form of a ring in inner wall surface and the outer wall surface of retainer ring.

Further, described protrusion is made up of soft rubber, and one-body molded with retainer ring and connecting rod.

Further, described connecting rod and retainer ring are one-body molded, make by soft rubber.

The beneficial effects of the utility model are: can be set with pen core in retainer ring, protrusion can increase the frictional force of pen core and retainer ring contact position, and the protrusion in retainer ring outer wall and connecting rod can increase and the frictional force of penholder contact position, so that pen core loads when using in penholder, do not produce to rock allow write more smooth smoothly.

Accompanying drawing explanation

Fig. 1 is the structural representation of the pen core holder that this utility model provides.

In figure, 1-retainer ring; 11-opening; 2-connecting rod; 3-protrusion.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.

As shown in Figure 1, a kind of pen core holder, including multiple retainer ring 1, connected by connecting rod 2 between each two retainer ring 1, described retainer ring 1 is provided with the opening 11 that can disconnect retainer ring 1, the inner wall surface of described retainer ring 1 and outer wall surface are equipped with protrusion 3, and the sidewall surfaces of described connecting rod 2 also is provided with protrusion 3.

As specific embodiment, main flow pen core owing to producing at present and use mostly is Chinese style, Korean style and Japanese refill of gel-ink pen, the core pipe overall diameter of this three formulas pen core is about between 4.5mm��5.5mm, and retainer ring 1 inner wall surface is additionally provided with protrusion 3, pen core it is mutually matched thus fixing pen core to can be located in retainer ring 1, the internal diameter of described retainer ring 1 is 5mm��7mm, can according to existing pen core dimensions, produce the pen core holder that the retainer ring 1 internal diameter specification matched is different, and when pen core tube external diameter is slightly larger, retainer ring 1 can easily be supportted bad by the pen core in retainer ring 1, and opening 11 just plays a cushioning effect, slightly larger pen core can form interference fits with retainer ring 1, the opening 11 of retainer ring 1 is strutted, but retainer ring 1 remains to coordinate with pen core very well fix.

As specific embodiment, in order to the frictional force increased between pen core and retainer ring 1, retainer ring 1 is provided with multiple non-slip process part 3, and all arrange in the form of a ring in inner wall surface and the outer wall surface of retainer ring 1, and when being mounted with that pen core holder rear connecting rod 2 can touch with penholder inwall, so also being provided with anti-skidding protrusion 3 in connecting rod 2, connecting rod 2 and retainer ring 1 are stuck between penholder and pen core, solve the problem rocked back and forth in penholder of pen core, make to write more smooth smoothly.

As specific embodiment, described protrusion 3 is preferably made up of soft rubber, and one-body molded with retainer ring 1 and connecting rod 2.

As specific embodiment, described connecting rod 2 and retainer ring 1 are one-body molded, it is preferable that be made up of soft rubber, and soft caoutchouc elasticity is high, better softness, are conveniently set with pen core, and pen core holder and pen core are loaded smoothly in penholder with the use of.

These are only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make; directly or indirectly it is used in other relevant technical fields, all in like manner within scope of patent protection of the present utility model.
