Abstract

The utility model relates to a novel discoloration ball-point pen for quickly writing, recording, labeling, duplicating, etc., which has the advantages of practicality, convenience and beauty. The novel discoloration ball-point pen is composed of a pen holder, a pen cap and a ball-point pen core with three colors. When the novel discoloration ball-point pen is used, only the pen holder is rotated to definite angle, while any discoloration switch does not need to be wrenched, and then three colors of red, blue and black respectively flow out on a ball-point pen head with a single core. If some color is needed, a color label of the color is upward, and then the color can flow out on the ball-point pen head with a single core. The utility model has the advantages of simple structure and quick discoloration, is conveniently used and carried, and can satisfy a user to quickly write, record, label, duplicate, etc. with multiple colors. The novel discoloration ball-point pen can be used for replacing color ball-point pens.

Description

Color ball-pen with single core

The utility model is that a post goes out the polychrome ballpoint pen, writes an a kind of novel variable color ballpoint pen that needs such as record, mark, manifolding fast especially for polychrome.

The polychrome ballpoint pen, its known method: a kind of is the polychrome ballpoint pen that is combined into by not homochromy ballpoint pen core, when using certain of the same colour, need move the switch that moves up and down of this look on the ballpoint pen with hand, this look ballpoint pen core is promptly released by link gear, its nib is exposed and uses.When need during with another color, ballpoint pen core of the same colour is return before also must be once more moving mobile switch on the pen and allow with hand, and required look ballpoint pen core just can be ejected, and uses not very convenient; Another kind is that the penholder and the cap for brush are arrested with hand respectively and relatively rotated, by rotation displacement switch certain ballpoint pen core of the same colour is ejected, because this ballpoint pen core of all kinds is to eject successively by rotation to return the location, so if when needing the third color, also need respectively preceding two kinds of color displacements eject return after, the ballpoint pen core of the third color is ejected, therefore by displacement, variable color speed is slow, uses also inconvenient.

Task of the present utility model is to simplify color changing structure, improves variable color speed, dwindles the penholder diameter, and it is streamlined to strengthen handwriting, accomplishes to use and wears conveniently, adapts to the needs that quick polychrome is write, writes down, marked and make carbon copies etc.

Below in conjunction with accompanying drawing, be described in detail the utility model.

Fig. 1 is the structural representation of utility model.

Fig. 2 is the enlarged drawing of the utility model ballpoint pen core (3).

Fig. 3 is the upward view of the utility model Fig. 2.

Fig. 4 is the vertical view of the utility model Fig. 2.

Structure of the present utility model is: by penholder, the cap for brush, ballpoint pen core and colour code Form, penholder (1) can be designed to multiple pattern with the cap for brush (2) or be designed to directly use ballpoint pen core (3) to replace the pure streamlined pen of penholder (1) without penholder (1). Ballpoint pen core (3) is the monoblock type ballpoint pen core that a post goes out three looks, it is made up of penholder (5) and nib (4), paste on the lower end disc of the cone plane that is imprinted on nib (4) or penholder (5) colour code (6) or (7), colour code is with the pen core look corresponding, and namely the color of colour code must be corresponding to the color of pen outflow.

The utility model is in use basic identical with the monochromatic ballpoint pen of normal tape cap, when the needs colour changing, only need rotate penholder (1), or when not having penholder (1), rotate ballpoint pen core (3) and allow the colour code (6) of selected color or (7) can be at this look of ballpoint pen head (4) outflow of same post up.

Ballpoint pen core of the present utility model, its nib (4) are that a post three holes go out three looks, and steel ball (9) is equipped with in the lower end of hole (8), and three look holes isolate not colour mixture separately mutually, during use, on same nib by separately independently steel ball roll to flow out separately color.Hole (8) in the nib (4) and the hole (10) in the ballpoint pen core bar (5) are tightly connected.Ballpoint pen core bar (5) also is a bar three holes, and three holes isolate mutually and inject three look ballpoint pen fluid respectively, and this from seeing in appearance than the thick slightly ballpoint pen core of common monochromatic ballpoint pen core, actual is three one-piece type look ballpoint pen cores.

Use this because of need not to move any colour changing switch, the color of conversion pen quickly and easily just, so it be applicable to that polychrome is write fast, writes down, marked, the needs of manifolding etc.This is owing to adopted a post to go out the ballpoint pen core of three looks, removed traditional variable color mechanism, institute is so that this pen is simple in structure, in light weight, materials are few, since the minimizing of penholder diameter, the exterior flow good linearity of pen, and pattern is novel exquisite, use is worn conveniently, be the renewal product of variable color ballpoint pen, therefore, it will be subjected to liking of people and welcome.

Claims (4)

1, a kind ofly be used for the variable color ball pen that needss such as manifolding were write, write down, marked to polychrome fast, this is by penholder, the cap for brush and be with one-piece type ballpoint pen core of polychrome of colour code to be formed.

2, quick variable color ball pen according to claim 1 is characterized in that this colour changeable pen one post is minimum and goes out three kinds of colors.

3, quick variable color ball pen according to claim 1 is characterized in that this refill for ball-point pen is made up of nib (4) and reservoir shaft (5).

4, quick variable color ball pen according to claim 2 is characterized in that this quick variable color positions variable color up with colour code (6).
