Description

Overlapping pen

The utility model relates to a kind of making of writing with plotting unit.

The inner core of existing pen as pencil wax crayon etc. is elongated, during use or need constantly cut the system nib, comparatively time-consuming taking a lot of trouble.

The purpose of this utility model is for making the overlapping pen of a kind of a plurality of writing units.

Technical solution of the present utility model is: the pen core of pen is the coaxial overlapping compositions of a plurality of writing units, each writing unit comprises an inner core and a pen core cover, inner core is tight in an end embedding of pen core cover, the other end of pen core cover can freely stretch into for another unit inner core, the writing unit of forming every pen can be 3 to 13.Inner core can have two kinds of structures with cooperating of pen core cover: a kind of is that the cover inwall has low-angle tapering, and another kind is to separate at the end of the sheathed interlayer of inner core with the tight pen core of embedding.Inner core mainly is a cylindricality inner core of graphite, colored wax moulding, the inner core of the pen of also short garden pearl pen core or other band printing ink, and the pen core cover is material injection mo(u)ldings such as engineering plastics.The utility model is to can be the pen that recycles a plurality of writing units, is particularly suitable for the pupil and uses, and one is equivalent to many pencils of cutting, and has also saved lead for retractable pencil, reusable.Multiple drawing pencil core from soft to hard can be housed during drawing, also multiple colored pencil lead can be housed, give drawing, colour painting, write etc. brings convenience.

The utility model is described in further detail below in conjunction with accompanying drawing: accompanying drawing is the structural representation of eclipsed form pen.Pen core cover 3, the cap for brush 6, penholder 1 is made by injection moulding or other thermoplastic, and an inner core 2 is a lead for retractable pencil, pen core puts an end of the tight pen core of embedding and establishes boss rank 4, the other end 5 perforates are bigger, can insert for an inner core of another writing unit and the coaxial many writing units pencil of boss rank cooperation composition, after most advanced writing unit lead for retractable pencil has been write, extract the unit of having write pen core from nib, this pen core cover is filled in penholder from afterbody, expose another writing unit pen core, the cap for brush is provided with one and ends protruding 7 in penholder.

Claims (2)

1, a kind of eclipsed form pen, by pen core, penholder is formed, it is characterized in that described pen core is that 3-13 coaxial overlapping writing unit formed, each writing unit comprises an inner core and a pen core cover, an end of the tight pen core of inner core embedding cover, and promptly this end internal diameter of pen core cover is less and have a tapering, perhaps establish an interlayer in the pen core cover, the other end internal diameter of pen core cover freely stretches into for the pen core of another writing unit greatly.

2, by the described pen of claim 1, it is characterized in that the two ends of pen core cover are respectively equipped with concavo-convex step: the boss rank of pen core end are embedded in the concave station rank of another writing unit pen core cover coaxial overlapping in order to pen core.
