Description

Large capacity multifunctional double head fountain-pen

The utility model belongs to novel fountain pen in the stationery class, its objective is at same branch penholder two ends and load onto two nibs, and the length of maintenance training pen and existing similar, make one can dual-purposely be easy to carry, and make its every end ink storage capacity 1.3 to 1.8 times for the existing conventional pen (single head) that adds water with barrel suction or ink cartridge, and the nib of not making dirty when adding water has the advantage of the clean nib of big capacity; The nib that adds various different purposes is supplied in groups, has more the function of using more.It is different from patent announcement number is 87204828 dichromatism fountain pen, and latter's structure is different fully with this pen, and adds water with ink cartridge.Its length is about about 1/3rd of ordinary fountain pen (single head), and therefore every chromatic ink storage capacity also is about about 1/3rd of ordinary fountain pen (single head).

This is to be newly-designed on the basis of 86204802 clean rip fountain pen with high capacity in my patent No., be characterized in that penholder length is about half of conventional pen (single head), respectively there is an internal thread at two ends, separate with dividing plate in the middle of the penholder inner chamber, make two ends not connected also air tight, the internal thread at penholder two ends can be connected with the external screw thread of pen on the exposed pen head of the attachment screw of hooded nib or various functions.After the transverse plane three of the transverse plane of the transverse plane at penholder two ends and attachment screw or pen (or with its illustration of being close to) and intermediate seal packing ring compresses close the contact through screw, can be linked to be two close gastight integral body, become the container of storage ink.Ink will flow to nib for the usefulness of writing or painting continually by an attachment screw or a pen middle aperture.The two part inks that separate can be that two kinds of colors are identical or different, also can be the identical or different ink of character (as supplying with the ink that " biro " also is " mound pen " usefulness), decide on demand.Ink injects the two ends inner chamber that penholder has screw with suction and injection device (dropper) sucking-off from ink bottle by the outside, or adds with portable ink bottle (as the eyedrops drop bottle), and also available little inkhorn injects, and is simple and efficient.Because though the every end of penholder inner chamber has only 1/4th left and right sides storage inks of the former length of penholder during ink, but it is the whole spaces that utilize the penholder inner chamber, therefore capacity still respectively is 1.3 to 1.8 times of existing training pen, has the advantage of the clean nib of big capacity.

Because this pen is without barrel, the Ink reservoir and the spring that absorbs water, so cost is lower.This pen is except penholder and the special injection moulding processing of seal washer need, and used nib all is a standard component, so gold fountain pen manufactory can use existing equipment and technology manufacturing.For the little factory of specially doing by part assembling lump-sum, also can order required standard component to the manufactured parts special manufacturer by designing requirement, add the assembling of homemade penholder and seal washer, easily give enforcement, the ink suction and injection device can be extremely low with plastic injection-moulded cost; Can be inserted on the free ink bottle cover, easy to use.As use the small bottle packing ink as the medicament for the eyes drop bottle to provide together, be convenient to the user and go out to carry, and can increase factory's economic benefit.As with little inkhorn ink, can make workmanship to kettle, it is also very refined to be placed on desk.

Except fountain pen (comprising pen, iridium-point pen, gold fountain pen, soft pen, drawing pen etc.) and ink garden pearl pen (mound pen) nib are all adorned in two ends, also can one be fountain pen, a dress garden pearl nib.A garden pearl penholder does not have the one end load of garden pearl and connects its external screw thread of screw and be connected with the internal thread of penholder.Because of garden pearl pen core tail end can stretch into the penholder inner chamber, so pen core can lengthen about 30 millimeters, effectively writing length is existing three times, solved the medium-term and long-term ink capacity that exists of existing ink garden pearl double-purpose pen very little with the too short problem of garden pearl pen core.Other structures of ball pen are with existing identical.

This pen also can be adorned the fountain pen nib by an end, end dress propelling pencil head.The connector of propelling pencil has external screw thread to be connected with fountain pen penholder internal thread, the middle porose lead for retractable pencil of adorning, the top props up fountain pen penholder inner chamber dividing plate, the lower end in hole tightly is enclosed within the lead for retractable pencil tube outside, the outer garden of lead for retractable pencil pipe then is slidingly matched with the pencil shaft endoporus, lead for retractable pencil pipe lower end and pencil stub part, structure is the same with existing propelling pencil.Pencil shaft is enclosed within the lead for retractable pencil tube outside, can be in axial sliding, and when pencil shaft was upwards made impulse movement, lead for retractable pencil just automatic forward feed was a bit of, and it acts on and pushes downwards and lift first sample.The propelling pencil length overall is advisable can adorn with 30 millimeters lead for retractable pencils, makes lump-sum length and existing fountain pen similar, and the two-headed pen of dress pencil stub can be the technical staff and draws to write and provide convenience.

The two-headed pen that the fountain pen nib is all adorned at two ends has two pens cap, and a band pen clip can be pen hanging in pocket; A no pen clip.But two pens cap require can two general.Have only a dress fountain pen nib, then have only the pen cap of band pen clip; One end of dress garden pearl pen or propelling pencil does not have the pen cap.Pen cap design should be shortened as far as possible, and is similar to guarantee lump-sum length and ordinary fountain pen.The nib design is being guaranteed under the prerequisite of writing quality, also should select it short and small, and is similar in the hope of lump-sum length and ordinary fountain pen (single head).

This sample pen becomes multipurpose, and easy to carry, multiple functional two-headed pen can improve and write efficient expansion range of application, has real economy to be worth and social benefit.
