Abstract
The utility model relates to a kind of pen core, particularly a kind of head exchanging pen core.This head exchanging pen core, comprises pen core tube and nib, it is characterized in that: described pen core tube and the middle elastic ring rubber blanket that is fixed on pen core tube inner side that is provided with of nib; The height of described rubber blanket equates with the height that nib injects pen core tube.The utility model is simple in structure, easy to use, reasonable in design, applying flexible, efficiently solve while using ball pen or gel ink pen, inadvertently fall on the ground or the ball of pen core ferrule front end comes off and causes whole pen core cannot continue the problem of using when writing, while having avoided change-fountain pen, because entering air in the middle of nib and ink, cannot continue smooth and easy problem of writing simultaneously.The utility model is convenient and simple, and saves limited resource and protection of the environment, is suitable for wide popularization and application.
Description
(1) technical field
The utility model relates to a kind of pen core, particularly a kind of head exchanging pen core.
(2) background technology
Ball pen or gel ink pen are that we write the instrument of commonly using.While using ball pen or gel ink pen, inadvertently fall on the ground sometimes, when writing, the ball of pen core ferrule front end can come off sometimes, this pen core just cannot have been write substantially, even if still there is unspent pen oil in the shaft of a writing brush, also to have to throw away, this is very waste just.In order to save limited resource and protection of the environment, we need a kind of pen core of replaceable pen point.Although current ball pen or gel ink pen nib can be changed, change and be difficult on the one hand, if wait until in addition that ink is finished to change with regard to easy generation air gap again, can not continue out ink marks.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of head exchanging pen core simple in structure, easy to use.
The utility model is achieved by the following technical solution:
A head exchanging pen core, comprises pen core tube and nib, it is characterized in that: described pen core tube and the middle elastic ring rubber blanket that is fixed on pen core tube inner side that is provided with of nib; The height of described rubber blanket equates with the height that nib injects pen core tube.
When using ball pen or gel ink pen, inadvertently fall on the ground or the ball of pen core ferrule front end comes off when writing, general common pen core just has no idea to continue to use, the utility model only need to rotate nib slowly and extract, and now the ring-shaped rubber pad between pen core tube and nib can expand along with extracting of nib; When nib is extracted completely, rubber blanket is complete turgor also, blocks air and enters into pen core tube; Now get one with the intact nib of ink, nib is inserted in rubber blanket gently, slowly rotate to prevent that air from entering in the middle of nib and ink, until nib contacts with ink, can normally write.
The utility model is simple in structure, easy to use, reasonable in design, applying flexible, efficiently solve while using ball pen or gel ink pen, inadvertently fall on the ground or the ball of pen core ferrule front end comes off and causes whole pen core cannot continue the problem of using when writing, while having avoided change-fountain pen, because entering air in the middle of nib and ink, cannot continue smooth and easy problem of writing simultaneously.The utility model is convenient and simple, and saves limited resource and protection of the environment, is suitable for wide popularization and application.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is rubber blanket plan structure schematic diagram of the present utility model.
Fig. 3 is the structural representation of the utility model while pulling up nib.
In figure, 1 pen core tube, 2 nibs, 3 rubber blankets.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises pen core tube 1 and nib 2, it is characterized in that: described pen core tube 1 and the middle elastic ring rubber blanket 3 that is fixed on pen core tube 1 inner side that is provided with of nib 2; The height of described rubber blanket 3 equates with the height that nib 2 injects pen core tube 1.
When using ball pen or gel ink pen, inadvertently fall on the ground or the ball of pen core ferrule front end comes off when writing, general common pen core just has no idea to continue to use, the utility model only need to rotate nib 2 slowly and extract, and now the ring-shaped rubber pad 3 between pen core tube 1 and nib 2 can expand along with extracting of nib 2; When nib 2 is extracted completely, rubber blanket 3 is complete turgor also, blocks air and enters into pen core tube 1; Now get one with the intact nib 2 of ink, nib is inserted in rubber blanket gently, slowly rotate to prevent that air from entering in the middle of nib 2 and ink, until nib 2 contacts with ink, can normally write.
