Description

A kind of lettering pen nib and lettering pen thereof

Technical field

The present invention relates to a kind of office appliance, relate to a kind of lettering pen nib specifically and use the lettering pen of this kind nib.

Background technology

In existing writing implement, there are various nibs to be applied in the writing process, for example ball-point pen tip, pen nib, fiber nib etc., be applied to various aqueous ballpoint pens, gel ink pen, oiliness ball pen, pen, marking pen, blank pen, e-Pointer etc. various have write or the product of mark function in, in above writing implement, have following problem in the use:

At first, in use, particularly the pupil brings into use in the process that pencil carries out the transition to other writing implements at three grades, because the pupil is accustomed to using this nib with certain frictional force of pencil, therefore when ball class lettering pen is used in conversion, for example when ball pen and gel ink pen, can be because the unconformable problem of the less appearance of frictional force of writing of this class writing implement, and what is more important is because the pupil generally coordination ability and wrist in the process of writing, scarce capacity is held in the control of finger, when using the less ball class writing implement of frictional force, it is wayward to occur writing stitching, not carefully and neatly done problem occurs writing.

At above problem, general teacher and parents' meeting require the student to use traditional pen as the transitional writing implement of this section, but the actual state at the homework book paper, when existing frictional force excessive, draws by traditional pen the phenomenon of paper, and traditional pen is because manufacturing process, and product is comparatively expensive, though pen helps resource and the raw-material saving of various writing implement, but in the use in enormous quantities, but there is the problem of ease of use and cost.

The pupil in use the situation that writing implement drops occurs through regular meeting, and Pen nib is easy to occur distortion and causes losing writing function owing to adopt foil material to form by the punching press sheet metal process.

Another one problem deserving of attention in the pen use is exactly that traditional pen is supplied with the nib ink by proposition, and the proposition operated by rotary motion is in a side of pen nib sheet material, therefore, and in writing process, pen has directionality, wherein have a side of proposition ink supply when paper, it is good writing, but pen is turned over turnback, proposition is during away from paper, writing quality can descend greatly, so nib writing end actual wear and use is a part wherein, and other parts are not utilized.

For addressing this problem, number of patent application is that the patent of CN96121492.9, CN02149184.4 has proposed a kind of new conical pen nib, form a plurality of broach shape sheet materials by technologies such as panel beatings, the slot between a plurality of broach shape sheet materials forms the ink supply path of a plurality of angles.Though this technical scheme has solved the presentation direction problem of pen, but improved the manufacture difficulty of nib, and because nib is the taper shape of many lobes, in writing process, since between the various piece in writing process owing to interact, nib is to the pressure of paper and produce elastic deformation and be subjected to spatial constraints, thereby the frictional force of writing process reduces significantly, can not reduce the problem that needs certain frictional force and low cost in the writing process and be easy to processing and manufacturing.

Secondly; in all kinds of writing implements; in order to improve the service life of writing implement; the various metal materials of general employing are realized the wear-resistant of nibs; such as all kinds of ball pens and all kinds of pen; can adopt various carbide alloy or noble metal as writing material; because what handwriting adopted in a large amount of writing implements is plastic cement material; therefore when the handwriting aged deterioration appears in regular meeting; but nib is intact situation still; cause performance surplus and waste of material, and caused the inconvenience of recovery in the writing implement that uses owing to the existence of metal penpoint.

Summary of the invention

Technical problem to be solved by this invention just provide a kind of low cost of manufacture, elastic deformation ability reach well anti-wear performance good the lettering pen nib and use this nib lettering pen.

The present invention adopts following technical scheme:

A kind of lettering pen nib, nib inside are provided with the blind hole for assembling relaying core, and the nib front portion begins along the nib longitudinal centre line one slot to be set from writing end, and this slot runs through with blind hole and is communicated with.

Further, the inner blind hole end-to-end distance that arranges of described nib is 0.5mm-5mm from the writing end length L.

Further, described nib writing end can be for facing directly or curve form, or face the combination with curved surface directly.

Further, described nib excircle is equipped with one and shrinks hoop, and this contraction hoop is interference fit with the nib excircle.

Further, slot width is 0.02mm-0.05mm on the described nib.

Further, described nib is made by the thermoplastic injection moulding.

Further, described nib is that polyformaldehyde, nylon 66 or polyether-ether-ketone are made by the carbon fibre material that adds 5%-40%.

Further, assembling relaying core in the inner blind hole of nib, the front end local surfaces of relaying core contacts with the interference of nib slot, and the rear end communicates with ink feeding system.

The invention has the beneficial effects as follows:

Lettering pen nib disclosed in this invention and lettering pen low cost of manufacture thereof, nib has the better elastic deformability, the balance of necessary friction and fluency when guaranteeing to write, and have the ability that certain wearability and nib writing end are fully used.

According to this technical scheme, because nib begins to have a local slot from writing end, can the writing end slot be narrowed down to the width value that has capillary force at ink by shrinking hoop, design is preferably the width of 0.02mm to 0.05mm, because the relaying core of supply ink and the slot of nib are arranged in nib inside comes round, when writing, constantly introduce the nib writing end for consuming from the relaying core by the capillarity ink, the concrete slot width that shrinks also can change according to the requirement that goes out the China ink amount or the variation of ink type thereupon.

The forming materials that nib preferably adopts polyformaldehyde, nylon 66, polyether-ether-ketone to strengthen by the carbon fiber that adds 5%-40%, guarantee that writing end and slot are partly for guaranteeing to have better elastic recovery ability and wear-resisting, impact resistance, and by adopt elasticity preferably material not only satisfied and write the moderate needs of frictional force, when falling, can guarantee good intensity and recovery capability simultaneously.

The writing end of nib stitching width as required and the demand of writing are set to face directly or curved surface, also can be set to the combination of the two, write demand thereby satisfy difference.Owing to adopt Shooting Technique to form by mould, therefore can stablize the various complicated writing end shape face of realization cheaply, for the design of writing implement provides good assurance.

Because nib, relaying core be along the axis symmetry, so the two sides can write, and takes full advantage of the writing end of nib, guarantees to have good writing the life-span.

Because the relaying core segment surface of nib inside should adopt interference contact with the nib blind hole internal surface, guarantee in the slot that imports to nib that ink can be good.

Use the lettering pen of this nib can adapt to multiple cartridge structure, such as direct-liquid type adjuster writing implement structure, cotton tubular type writing implement structure, change capsule formula writing implement structure etc., have adaptability widely.
