Abstract

The invention discloses a ballpoint pen with a spiral cartridge. The ballpoint pen is provided with a spiral body, and one end of the body extends to form a writing end. In addition, the ballpoint pen also can be provided with two spiral bodies which rotate around the same axis, and opposite ends of the two bodies respectively extend to form a writing end, so that a double-end and double-color pen can be formed. More ink can be accommodated in the ballpoint pen, so the ballpoint pen can be used for a longer time, excessive discarded penholders and accessories thereof cannot be generated, and the ballpoint pen has the environmentally-friendly effect.

Description

A kind of ballpoint pen tool with spiral pen core

Technical field

The present invention relates to a kind of ballpoint pen tool, relate in particular and a kind of the pen core body is made as helical form, to increase the ballpoint pen tool of the ccontaining amount of body interior ink with spiral pen core.

Background technology

The pen core of existing traditional ballpoint pen is tube shape always, the ink volume that pen core holds is π D2L/4, D is the internal diameter of straight tube pen core, and L is the length of straight tube, and the ink volume is directly proportional with D square apparently, also be directly proportional with the L first power, increase the ink of pen core, if by lengthening straight tube pen core length several times, then pen core length is obviously oversize and unrealistic, if by strengthening the straight tube internal diameter, then ink has mobile anxiety arbitrarily.

In addition, M240358 number disclosed revolving type double-core pen that can be luminous of TaiWan, China patent, it includes the shaft of a writing brush and the following shaft of a writing brush, wherein, be provided with the twin-core switch unit in the following shaft of a writing brush, the upper end of twin-core switch unit and the interlocking of the last shaft of a writing brush, the turn portion that can make the twin-core switch unit when last shaft of a writing brush turn is subjected to turn and the switching that produces pen core, go up again and be provided with luminous group in the shaft of a writing brush bottom, following shaft of a writing brush top is provided with electroplax and luminous group and offsets, when the swing angle of electroplax and luminous group was off-position, luminous group was not promptly luminous; When the swing angle of electroplax and luminous group is conduction state, luminous group promptly produces radiance and penetrates from the set printing opacity cover in last shaft of a writing brush top, but still there is following shortcoming in it, it uses the pen core of vertical type, its inner can being restricted by ccontaining quantity of ink, cause discarded penholder and accessory thereof after the too much use easily, cause waste resource and contaminated environment.

Summary of the invention

The object of the present invention is to provide a kind of ballpoint pen tool, cause the discarded penholder after the too much use and the problem of accessory thereof to solve in the prior art defective that can ccontaining quantity of ink be restricted with spiral pen core.

In order to reach above-mentioned purpose, first solution of the present invention is:

A kind of ballpoint pen tool with spiral pen core comprises a body, and it is shape in the shape of a spiral, and this body one end also extends and is provided with a writing end.

This spiral helicine body is encircled a support bar.

This ballpoint pen tool also comprises one first hollow penholder, and it stretches through into usefulness for this body.

The sheathed cover plug of this first hollow penholder, one end, the other end then is provided with a binding end, and a pen cap is set is linked in this binding end, and this body stretches through behind this first hollow penholder, its writing end this pen cap that stretches through out.

Second solution of the present invention is:

A kind of ballpoint pen tool with spiral pen core comprises body, and it is set to two, and is around the rotating helical form of same axis, again the end that these two bodies are relative and extend respectively a writing end is set.

Encircle a support bar around the rotating helical form body of same axis for these two.

This ballpoint pen tool also comprises one second hollow penholder, stretches through into usefulness for above-mentioned body.

These second hollow penholder two ends are provided with a binding end respectively, and a pen cap is set respectively is linked on this binding end, and these two bodies stretch through behind this second penholder, its writing end this pen cap that stretches through out respectively.

After adopting said structure, by adopting above-mentioned spiral helicine body, its length can be according to the helical length of every single pitch P

Calculate, wherein S is a helical length, a is the distance of the spiral axis of rotation A of body to the body center, c (=P/2 π) is the pitch increment Delta P/ Δ θ of per unit angle θ, significantly increased body length, and body of the present invention and traditional pen core are relatively, can increase by 20 times of ink capacities approximately, specifically see also Fig. 7 and shown in Figure 8.The present invention has following advantage:

One, body of the present invention presents helical form, and its inside can ccontaining more inks, and can use more for a long time, can not cause discarded penholder and accessory thereof after the too much use, thereby have the environmental protection effect.

Two, pattern of the present invention is multiple, its body can use separately, also can further be built in the hollow penholder or encircling a support bar by this body, to increase support force, also can form around the rotating helical form pen core of same axis in addition by two bodies, and its writing end is separately positioned on corresponding two ends, thereby form double-colored tool of double end.
