Abstract

The utility model relates to an environment-friendly ball pen, comprising a pen holder, printing ink, pen holder threads, a pen nib, pen nib threads, a piston, a pen holder tail cover, pen nib sealing rubber and a pen sleeve, wherein an inner cavity of the pen holder is directly filled with the printing ink to lead the pen holder and a pen core shell to be into a whole body; the pen holder and the pen nib are closely connected by threads; the tail end of the inner cavity of the pen holder is provided with the piston connected with the printing ink; and the piston can move with the printing ink; the pen nib is provided with the sealing rubber so as to lead the printing ink in the pen nib not to outflow and be seared before the pen nib is replaced. The durable environment-friendly ball pen has simple structure, durable printing ink, easy replacement of the pen nib and environmental protection, and is especially suitable for an occasion which needs the ball pen to write a lot.

Description

A kind of durable environmental protection ball pen

Technical field

The utility model relates to a kind of ball pen of writing usefulness, especially a kind of ball pen durable, environmental protection.

Background technology

Ball pen is a kind of writing implement that is in fashion the world nearly recent decades.It has simple in structure, easy to carry, write lubricatedly, and be suitable for being used for advantage such as manifolding, thereby the people from all walks of life such as civilian personnel from the student of school to office building are happy to use.Ball pen is different with fountain pen, because what its used is to do consistence printing ink, printing ink is again to rely on nib to go up the steel ball that freely rotates to bring out transcription to paper, thus non-leakage, not influenced by climate, and writing time is longer, and having saved needs the often trouble of perfusion ink.But the people who writes in a large number for needs; big capacity ball pen (the diameter 5mm or the 7mm of core) capacity on the market still is not enough now; need often change core; often run into also that printing ink does not use up and situation that ball damages; this has not only increased use cost, and discarded core has become also not environmental protection of rubbish.

Summary of the invention

Also not very long in order to overcome existing ball pen writing time, diligent change-fountain pen core waste material, change the shortcoming that a large amount of pen cores is dropped not environmental protection, this practical row provides the environmental protection ball pen that a kind of ball pen ink is more durable, can make things convenient for the change-fountain pen head.

The technical scheme that its technical problem that solves the utility model adopts is:

The direct charge of oil China ink of the inner chamber of penholder unites two into one pen core shell and penholder, at inner chamber tail end (other end of nib end) piston is arranged, to stop printing ink to leak from tail end, the nib end of penholder has screw thread, and nib also has screw thread, the nib with penholder by being threaded, be convenient for changing nib.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing is the utility model structural representation.

1. penholders among the figure, 2. printing ink, 3. penholder screw thread, 4. nib, 5. written screw thread, 6. piston, 7. penholder tail-hood, 8. written sealing compound.

In the drawings, penholder 1 inner chamber directly is equipped with printing ink 2, the nib end shrinks rear with penholder screw thread 3, that written screw thread 5 (can be internal thread above the nib 4, it also can be external screw thread, but must be opposite with the penholder screw thread, closely connecting by screw thread), only drawn among the figure penholder internal thread and this structure of written external screw thread. Filled with printing ink during the inherent production of nib, seal with sealing compound 8 then, to protect the printing ink in the nib, printing ink can not flowed out and dry up, when needing to change nib, earlier with penholder nib end up, in order to avoid the printing ink in the penholder leaks, with the hand-screw head of starting writing, change old nib then, the sealing compound of new nib is torn off, screw new nib and get final product; The other end of penholder is penholder tail-hood 7, at the penholder inner chamber piston 6 is arranged, and is connected with printing ink, and stoping the outflow of printing ink, when printing ink 2 is used fewer and fewerily, piston 6 can be followed printing ink in the effect of atmospheric pressure and be moved to the nib end.

The specific embodiment

In the embodiment of accompanying drawing, we are that example further specifies the utility model to implement a kind of durable environmental protection ball pen:

Penholder 1 and penholder screw thread 3: use the plastics one-shot forming, 12 millimeters of penholder internal diameters, long 13 centimetres.

Printing ink 2: the printing ink that uses common ball pen.

Nib 4: roughly the same with common ball pen head, different is in the upper end screw thread to be arranged, and also has sealing compound.

Piston: the plastics one-shot forming, diameter is more smaller than penholder internal diameter, is having under the lubricated oil condition, can move freely in penholder and be advisable.

Which is an internal thread for penholder screw thread 3 and written screw thread 5, which is an external screw thread, as long as on the contrary, if just penholder is made internal thread, nib just must be made external screw thread, penholder is made external screw thread, and nib must be made internal thread, in a word, nib closely links together by screw thread with penholder, for nib, can send several with product, also can directly buy in the shop.

For the pen cap (not drawing among the figure), can adopt the turncap formula, cover that ball pen head is contained on the penholder and can turn on penholder with turncap, written hole is arranged at the turncap top, and ball pen head exposes from written hole during the turncap precession; Turncap can screen ball pen head when screwing out; Also can adopt other modes, the pen cap has mature technique in a word, no longer describes in detail here.

Claims

1. durable environmental protection ball pen, form by penholder, printing ink, penholder screw thread, nib, written screw thread, piston, penholder tail-hood, written sealing compound, the pen cap, it is characterized in that: on the penholder with on the nib opposite screw thread is arranged, just penholder is an internal thread, nib is an external screw thread just, penholder is an external screw thread, and nib is an internal thread just, and nib closely is connected by screw thread with penholder.

2. a kind of durable environmental protection ball pen as claimed in claim 1, it is characterized in that: have piston to be connected with printing ink at the penholder inner chamber, piston can move with printing ink.

3. as claim 1 or the described a kind of durable environmental protection ball pen of claim 2, it is characterized in that: sealing compound is arranged on the nib, the printing ink in the nib can not flowed out and dry up before changing nib.
