Abstract

This utility model provides a kind of pen for being adapted to various pen cores, including the pen cap, it is characterised in that：Some pen core decks are provided with its pen cap.The different deck in position has internal diameter of different sizes, and its effect is the pen core for allowing external diameter to be less than deck internal diameter, can pass through deck, allows external diameter to be more than the pen core of deck internal diameter, it is impossible to by deck, so as to be fixed from the pen core by deck.The pen core that this invention makes length different with external diameter can be used interchangeably, and improve the replaceability of pen core, reduce the use cost of user, reduce the pollution to environment.

Description

It is adapted to the pen of various pen cores

Technical field

This utility model is related to technical field of stationery, especially a kind of pen for being adapted to various pen cores.

Background technology

At present, the pen commonly used in people's life is gel ink pen and ball pen.On market, the species of pen is a lot, corresponding pen core Species is also a lot.

When the pen core of pen in handss is finished by people, it is impossible to when writing again, can typically select to buy refill, or directly Pen is abandoned, pen is bought again.Pen includes pen core and the pen cap, all directly abandons if pen bought again if being finished pen core every time, The raising of use cost and the pollution of environment certainly will be caused.Refill is not only thrifty but also environmentally friendly way.

Refill, the new pen core replaced need, as the pen core profile for originally using, to can be only achieved best making Use state.Because the length and external diameter of variety classes pen core are different from, it is possible that occurring, user is wanted to change pen core Species, but the pen core newly bought is different with original pen core profile, causes new pen core and the former pen cap not to coordinate, it is impossible to use Problem.

The content of the invention

The purpose of this utility model is to solve the problems, such as that different pen cores cannot be replaced.In order to realize purpose and other correlations Purpose, this utility model provide a kind of pen for being adapted to various pen cores, including the pen cap.

The technical scheme is that：It is adapted to the pen of various pen cores, the different position in the pen cap is provided with a number of Deck.

The deck is made up of some boss, is similar to tubular structure on the whole.

The deck has the internal diameter of oneself, and its effect is the pen core for allowing external diameter to be less than deck internal diameter, can pass through card Seat, allows external diameter to be more than the pen core of deck internal diameter, it is impossible to by deck.

The deck boss and intransitable pen core tail end contact squeeze, pen core tail end are blocked by deck, make pen core solid It is scheduled in the pen cap.

The internal diameter size of the deck in the pen cap, successively decreases from front to back step by step.Deck before the pen cap, its deck Internal diameter is big, and the larger pen core of external diameter can be stuck, and the less pen core of external diameter, afterbody can be by the above big deck of internal diameter, quilt The little deck of internal diameter is blocked below.

Using above technical scheme, following beneficial effect can be reached：

This utility model provides a kind of pen for being adapted to various pen cores, including the pen cap, is adapted to length pen core different with external diameter Use, improve the replaceability of pen core, reduce the use cost of user, reduce the pollution to environment.

Description of the drawings

In order to be illustrated more clearly that this utility model example or technical scheme of the prior art, below will be to embodiment or existing Accompanying drawing to be used needed for having technology description is simply introduced, it should be apparent that, drawings in the following description are only this reality With some new embodiments, for those skilled in the art, on the premise of not paying creative work, also Other accompanying drawings can be obtained according to these accompanying drawings.

Fig. 1 is a kind of use state of pen in this utility model example；

Fig. 2 is a kind of use state of pen in this utility model example；

Fig. 3 is a kind of use state of pen in this utility model example；

In figure, 1 is the pen cap；2.1st, 2.2,2.3 is the length pen core different with external diameter respectively (2 is the general name of different pen cores)； 3.1st, 3.2,3.3 is internal diameter deck of different sizes respectively (3 is the general name of different decks).

Specific embodiment

To make purpose, technical scheme and the advantage of this utility model example clearer, below in conjunction with this utility model reality The accompanying drawing in example is applied, the technical scheme in this utility model example is clearly and completely described, it is clear that this described reality With new a part of embodiment, rather than the embodiment of whole.Based on the embodiment in this utility model, the common skill in this area The other embodiment obtained under the premise of creative work is not made by art personnel, belongs to protection model of the present utility model Enclose.

Pen core 2.1,2.2,2.3 in figure, the length of its length are increasingly longer in order, and the size of its external diameter is got in order Come less.Deck 3.1,3.2,3.3 in figure, the size of its internal diameter are less and less in order.

In Fig. 1, pen core 2.1 loads in the pen cap 1, and the external diameter of pen core 2.1 is more than the internal diameter of 3.1 decks, and tail end cannot pass through 3.1 decks, are blocked by 3.1 decks, pen core 2.1 is fixed in the pen cap 1.

In Fig. 2, pen core 2.2 loads in the pen cap 1, and the external diameter of pen core 2.2 is less than the internal diameter of 3.1 decks, more than in 3.2 decks Footpath, tail end can pass through 3.1 decks, it is not possible to by 3.2 decks, blocked by 3.2 decks, make pen core 2.2 be fixed on the pen cap 1 In.

In Fig. 3, pen core 2.3 loads in the pen cap 1, and the external diameter of pen core 2.3 blocks less than 3.1 and 3.2 more than the internal diameter of 3.3 decks Seat internal diameter, tail end can pass through 3.1 and 3.2 decks, it is not possible to by 3.3 decks, blocked by 3.3 decks, fix pen core 2.3 In the pen cap 1.

Wherein the pen cap is detachable, and the deck quantity in the pen cap is not limited, and can be three, or two. The architectural feature of deck is not limited, and can be that the internal diameter of equally distributed boss, or the pen cap is of different sizes, into ladder Shape distribution is constituted.

Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
