Abstract

The utility model provides a multi-color pen comprising a pen casing, a rotary cover, a plurality of pen cores, a plurality of push keys and a plurality of springs, wherein the rotary cover is mounted at the upper end of the pen casing through a thread structure; each of the push keys is mounted on the rotary cover, and is in a barrel type structure with an opening at the lower end; and the lower end of each of the pen cores is provided with the spring and is inserted into the push keys. Through the design of the multi-color pen, a plurality of pen cores of different colors are mounted in the pen, thereby facilitating the replacement of the pen core and satisfying the requirements for plural colors during writing or drawing.

Description

Multi-colour pen

Technical field

The utility model relates to a kind of pen, relates in particular to a kind of pen that can write out multiple color font or draw multiple color lines.

Background technology

Pen is the of paramount importance writing implements of people, and now various multifunctional pens emerge in an endless stream on the market, from carrying the pencil of rubber in early days, has the pen of additional various functions such as clock up till now, for people's use provides many facilities.But people can use the lines of multiple color when drawing; And when writing, also can run into the situation of the multiple color font of needs as separator, if prepare the pen of a plurality of different colours, obviously be a loaded down with trivial details thing.

The utility model content

The utility model provides a kind of Multi-colour pen, and the pen core of a plurality of different colours is installed in the one-pen, can change pen core easily, with satisfy write or when drawing to the needs of multiple color.

The Multi-colour pen that the utility model provides comprises a shell and a plurality of pen core, also includes a plurality of promotion keys, a plurality of spring and swivelling cover; Wherein, described swivelling cover is installed in a shell upper end by helicitic texture; Described promotion key is installed on the swivelling cover, and promoting key is the barrel-like structure of lower ending opening; Described pen core inserts and promotes in the key, and the pen core lower end is equipped with spring; Described promotion key internal diameter and pen core external diameter are complementary, and pen core, spring are consistent with promotion bond number amount.

Wherein, the described promotion key barrel-like structure that is multiple color.

Wherein, described pen core is refill for ball-point pen, pencil-lead or Neutral ball-point for ball-point pen.

Further, described pen core color can be single or multiple color.

Further, when described pen core color is multiple color, described promotion key color and the pen core solid colour that is installed on it.

Wherein, described shell is plastic housing.

The utility model Multi-colour pen is installed in a plurality of pen cores in the one-pen simultaneously, can change the pen core color easily by the promotion key that promotes the pen core correspondence; The design of swivelling cover can be changed pen core easily when pen core uses up; Pen core lower end mounting spring can utilize spring pushing to pen core, the promotion key of the required pen core correspondence of easier promotion when needs are changed the pen core color.

Description of drawings

Fig. 1 is the cross-sectional view of the utility model Multi-colour pen.

The specific embodiment

With reference to Fig. 1, specifically describe as follows to the utility model Multi-colour pen:

The utility model Multi-colour pen comprises a shell 1, a plurality of pen core 3, a plurality of promotion key 4, a plurality of spring 5 and swivelling cover 2.Wherein, a shell is a plastic housing; Promoting key 4 is the barrel-like structure of lower ending opening, and its internal diameter and pen core 3 external diameters are complementary, and each promotes key and has different colours; Pen core 3 can be refill for ball-point pen, pencil-lead or Neutral ball-point for ball-point pen, and as required, its color can be single or multiple color; Pen core 3, spring 5 and promotion key 4 quantity are consistent.

Swivelling cover 2 is tightened the upper end that is installed in a shell 1 by helicitic texture, promotes key 4 and is installed on the swivelling cover 2; Pen core 3 is inserted in the promotion key 4, and pen core 3 lower ends are equipped with spring 5; When pen core 3 colors are multiple color, the color of described promotion key 4 and the pen core that is installed on it 3 solid colours.

When pen core 3 is solid color, when one of them pen core is used up, can change other pen cores at once, and not need to prepare in addition other pen or pen cores, one-pen can be used as many pens and uses.

When the pen core of the multiple color of needs, versicolor pen core 3 is installed in the promotion key 4 of corresponding color, promote pairing promotion key 4, can be easily with the pen core that changes required color.

When pen core 3 uses up, back out swivelling cover 2, can change pen core easily.

More than specific embodiment of the utility model is described in detail, but it is as example, the utility model is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that this practicality is carried out and substituting also all among category of the present utility model.Therefore, not breaking away from impartial conversion and the modification of being done under the spirit and scope of the present utility model, all should be encompassed in the scope of the present utility model.
