Description

A kind of ball pen

Technical field

The utility model relates to a kind of ball pen, relates in particular to a kind of through improving the ball pen that the printing ink memory space increases the service life.

Background technology

Ball pen is the invention of a greatness, and the crystallization of human civilization has promoted the develop rapidly of cultural undertakings.It generally includes aqueous ballpoint pen, oiliness ball pen and neutral ball pen, no matter belongs to any, all comprises a pen container and pen core.Said pen container is used to grip, and said pen core is used to write.Concrete, said pen core comprises a nib and a body again, and the ball in the nib rolls on paper, and the printing ink that a body stores is reserved vestige one at paper.Because the ball pen pen container is can be nonexpondable, but pen core cannot reuse, the expensive material of making nib simultaneously is difficult for reclaiming, the plastics of making a body are easy to cause environmental pollution again, therefore, people expect to prolong the service life of single pen core.Usually, the wearing and tearing that the nib steel ball is arranged in decision ball pen life-span and the depletion rate of printing ink.Along with the material development of science and technology, the steel ball wear problems is solved.Therefore can only start with from improving total printing ink storage level.Existing cylindrical pen core increases total oil reserve and must increase length or increase sectional area, increase length can make pen container also corresponding lengthening, causing becomes burden with convenient celebrated ball pen.Increase sectional area again with the written incompatible of sectional area restriction arranged.Between this, prior art has necessity of further improvement.

The utility model content

The technical problem that the utility model will solve is to provide a kind of ball pen, and the storage level that can improve printing ink in the pen core is to increase the service life.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme.

A kind of ball pen comprises pen container and the pen core that is positioned at pen container, and said pen container comprises skull and stack shell, and said pen core comprises a nib that is used to write and a body of laying in printing ink, and said nib is fixed between said skull and the stack shell, and said pen is as spirality.

This ball pen according to the utility model; Said skull has the conical surface; Said pen container is fixed on the said skull and to the said conical surface and internally extends first location division; Said nib has second location division, and said second location division one side is resisted against on the said conical surface, and opposite side is resisted against on said first location division.

According to this ball pen of the utility model, the pitch of said body is 1cm to 2cm.

According to this ball pen of the utility model, said ball pen is a gel ink pen.

Use the beneficial effect of the utility model to be: the pen that is used to lay in printing ink can increase the storage level of printing ink as spirality, extends working time.

Part description of reference numerals: comprise pen container 1, stack shell 101, skull 102, friction part 103, tail-hood 104, the conical surface 105, first location division 106, pen core 2, nib 201, a body 202, second location division 203.

The specific embodiment

Below in conjunction with accompanying drawing this ball pen of the utility model is done further detailed description.

The embodiment that Fig. 1 to Fig. 4 provides for the utility model, this ball pen comprises pen container 1 and the pen core 2 that is positioned at pen container 1, and said pen container 1 comprises skull 102 and stack shell 101, and said pen core 2 comprises a nib 201 that is used to write and a body 202 of laying in printing ink.

Pen container 1 also comprises friction part 103 and tail-hood 104, and friction part 203 is positioned at the position that the user hands, to increase frictional force.Friction part 103 can be like the strip fin in the present embodiment, also can be the lattice-like salient point.Tail-hood 104 is fixed on the stack shell 101, and is positioned at the side away from skull 102.

Understand that the tail-hood 104 of present embodiment is not resisted against the tail end of pen core 202 fully, it is mainly used in protection pen core 202, rather than fixing pen core 202.The fixed form of pen core 2 such as following.In Fig. 3; Said stack shell 101 is fixed on the skull 102 and to the conical surface 105 and internally extends first location division 106; Said written 201 have second location division 203, and said second location division 203 1 sides are resisted against on the said conical surface 105, and opposite side is resisted against on said first location division 106.

Less pitch can store more printing ink, but the too small printing ink that can influence of pitch gets into nib, even causes printing ink to interrupt.In the present embodiment, the pitch P of a body 202 is 1cm to 2cm.In addition, in the utility model, said ball pen can be aqueous ballpoint pen, oiliness ball pen or gel ink pen.

Comprehensive the above; The technical scheme of the utility model can fully effectively be accomplished above-mentioned utility model purpose; And the structural principle and the principle of work and power of the utility model all verified in an embodiment fully, and can reach the effect and the purpose of expection, and the embodiment of the utility model also can carry out conversion according to these principles; Therefore, the utility model comprise all in claim, mention in the scope all the replacement contents.Any equivalence of in the utility model claim, being done changes, and all belongs within the claim of this case application.
