Abstract

The utility model relates to a multi-colour writing implement. A plurality of ink storage cores are arranged in a penholder, one end of each pen core in pen seats is extended into the penholder and contacts with the ink storage cores respectively, and the other end of the pen core is extended from the pen seats as a pen point, wherein, the number of the pen cores is identical with the numbers of the ink storage cores. Adhesive objects are filled in the gaps among the pen points, so that the pen points keep definite distance from each other, and the pen points are fixed in through holes of each of the pen seats without contact. Accordingly, the utility model enhances the intensity of the pen points. Because the adhesive objects have better anti-permeability, the multi-colour writing implement can also effectively prevent ink exudation on the surface of the pen points and obstruct different colour inks among the pen points from getting colour and color mixture.

Description

Multi-colour writing implament

The utility model relates to a kind of multicolor writing tools, and is especially relevant with Multi-colour fountain pen.

Existing multicolor writing tools mostly is a pen core of putting into the racemosus different colours in same branch pen container, reaches by mechanism alternation pen core upper-lower position to change the requirement of writing color, as double-colored or monochromatic ballpoint pen etc.Also the someone proposes the imagination of the polychrome watercolor pencil of multi-stylus in recent years.Because the pen core of watercolor pencil all adopts porous synthetic fiber to make, the capillarity of pen core easily produces scurries look, colour mixture between nib.This problem never finds effective solution for many years, so the imagination of polychrome watercolor pencil does not realize so far.

The purpose of this utility model provides a kind of scheme of scurrying look, colour mixture between the Multi-colour fountain pen pen core mutually that solves, and makes polychrome watercolor pencil practicability.

The purpose of this utility model realizes in the following way.A kind of multicolor writing tools, comprise penholder and pen stand, be provided with several water storage core in the penholder, one end of penholder is sealed, the other end and pen stand join, be provided with the pen core that number equates with the water storage core radical in the pen stand, an end of pen core stretches into penholder and contacts with water storage core, and the other end stretches out pen stand as nib.Its invention is characterised in that nib does not connect mutually and separates, and fills gap and fastened to each other by the viscose glue thing between pen core.

The utility model is filled the viscose glue thing and is fixed together with making it to keep certain spacing between nib.So not only improved the intensity of nib because the viscose glue thing has anti-permeability preferably, also can stop effectively nib surface ink ooze out and intercept different colours ink between nib scurry look and colour mixture.

Principle of the present utility model is further illustrated in explanation below in conjunction with embodiment.

Embodiment 1

Referring to Fig. 1.In the present embodiment, the water storage core 7.7.7 that contains three kinds of different colours inks is arranged in the penholder 9, and the upper end cover 17 of penholder 9 is sealed, but has a return-air hole 10 on this end face.Pen stand 4 intercalations are in the other end of penholder 9, and an end of three pen cores 2.22 contacts with three water storage core 7.7.7 respectively, and the other end passes the through hole of pen stand 4 as nib.Be filled with sicker 3 between the nib, make that nib is separated from each other not to be contacted, and be fixed in the through hole of pen stand 4.

When writing,, just can obtain the different colors of writing as long as rotating penholder 9 makes the pen core of different colors contact with paper.

Embodiment 2.

Referring to Fig. 2 to Fig. 3.Present embodiment is provided with three axially extended muscle 6 five equilibrium on the inwall of penholder 9.The upper end of water storage core 7 be provided with a wind wheel shape on spacer 8a and be provided with a following spacer 8b who offers three symmetrical holes that are 120 ° of distributions mutually in the lower end of water storage core 7.Three holes on the following spacer 8b all are inverted cone shape, and its maximum aperture is slightly larger than the diameter of water storage core 7, are provided with three little return-air holes 18 in addition on the next door in these three back taper holes, with the angle of back taper hole 8b be 60 °.(return-air hole 18 can be 1 or individual arbitrarily).Following spacer 8b can make in the penholder 9 of packing into after one also can be made in addition with penholder 9.Water storage core 7 its lower ends are placed on down in the taper hole of spacer 8b, and its upper end is separated by the last partition 8a of muscle 6 and tail benefit 17 axial restraints, and after tail benefit 17 on the upper-end caps of penholder 9, water storage core 7 is just separated mutually.The cross section that pen stand 4 is made up of written seat 4a and nib seat 4b, the cross section of through hole is the triangle that the top of the horn is a circular arc, and the nib of pen core 2.2.2 stretches out circular arc one side that through hole ground leans against triangle respectively, and the centre is inserted with a nib spacer 1.Pen core 2, the space between nib spacer 1 and through-hole wall is filled by sicker 3, and fastened to each other.Have a return-air hole 5 on the side of nib seat 4a, other is provided with one and debates the structure (being provided with diagram) that look is used, and writes the book color with indication.After installing penholder 9 and pen stand 4 as stated above, on the hole of falling iron of following spacer 8b, coat adhesive, pen core 2.2.2 is aimed at the back taper hole respectively, the lower end of pen stand 4 intercalations being gone into penholder 9 is integral, and pen core 2.2.2 stretches into respectively also that water storage core 7.7.7 is adhered to one another to live, and then the nib grinding is gone out R and has just become Multi-colour fountain pen.

For fluency that keeps writing and the generation that prevents to scurry color contamination look phenomenon, nib through repeatedly experimental results show that

embodiment

1 or 2 preferably keeps the interval of 0.5-0.7 millimeter, the diameter of nib is 0.8 millimeter, and coning angle is the interval of 45 ° of-70 ° of millimeters, and coning angle R is 0.25 millimeter.

Embodiment
