Description
Technical field
The utility model relates to the writing implement technical field, particularly a kind of gel ink pen nib.
Background technology
Gel ink pen is present popular in the world a kind of novel writing implement, and gel ink pen is the writing implement that belongs to one type of ball pen.The writing implement that utilizes the ball rolling to take writing medium (ink or printing ink) out of is referred to as ball pen.And in reality, be that the pen of oiliness is called ball pen with writing medium only; The pen of the viscosity of writing medium between water-based and oiliness is called gel ink pen.
Gel ink pen originates from Japan, because gel ink pen is write comfortable feel with the advantage of fountain pen and ball pen, therefore quite receives liking of people, and development in recent years is rapid.Gel ink pen has become maximum a kind of writing implement of using in our work, the study.Being in great demand to gel ink pen in the market.According to statistics, only the annual gel ink pen nib that consumes of Chinese market has 10,000,000,000 approximately, and nib is metal material manufacturing entirely.
Make the gel ink pen nib with metal material, the cost of raw material is high, equipment has high input, return period is long, has caused higher and can not definitely guarantee environmental protection with the written whole cost of made gel ink pen.
The utility model content
In view of this, it is a kind of with the gel ink pen nib of mixing polyformaldehyde Pom made that the utility model provides, to reduce the cost that the gel ink pen nib is made.
For realizing above-mentioned purpose, the utility model provides a kind of gel ink pen nib, is used for fixing an end that is installed in China ink under the printing ink pipe, comprises tube connector and nib, and said tube connector is fixedly connected or is wholely set with nib;
The oil ink passage that mutual perforation is arranged in said nib and the said tube connector;
The inside of said nib is provided with ball and is bowl-shape ball seat in the position near the tip, ball is arranged in the ball seat and can freely rolls;
Said nib is processed by mixing polyformaldehyde Pom material.
Preferably, the shape of said nib is a bullet shaped, and the head of said nib is that cone, afterbody are cylinder.
Preferably, said tube connector is shaped as the cylinder bodily form.
Preferably, the diameter of said tube connector cross section is less than the diameter of nib afterbody cross section.
Preferably, said ball seat is positioned at oil ink passage near the most advanced and sophisticated position of nib head.
The ink tank that the five-pointed star shape preferably, is arranged bottom the said ball seat.
Preferably, the rim of a bowl of said ball seat is towards nib head tip direction, and opening part is the closing in shape, and said ball seat encases ball.
Preferably, said tube connector has chamfering away from an end of nib.
The gel ink pen nib that the utility model provided; Be with mixing Pom (polyformaldehyde) made; Because the price of Pom material is more cheap than metal material, almost the cost of material is to ignore, also than being easier to processing; Thereby the equipment input cost of making is also lower, so lowered manufacturing cost with Pom made gel ink pen nib.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the ball socket structure sketch map of the utility model specific embodiment.
The specific embodiment
The core of the utility model provides a kind of gel ink pen nib, and this gel ink pen nib is by mixing Pom (Polyoxymethylene, polyformaldehyde) made, by special equipment production.Said gel ink pen nib comprises tube connector and nib; Tube connector is fixedly connected or is wholely set with nib; The oil ink passage that mutual perforation is arranged in said tube connector and the nib; The tip portion of said nib is provided with ball and is bowl-shape ball seat, and ball seat encases ball makes ball be difficult for from ball seat, coming off, and ball can freely roll in ball seat.
In order to make those skilled in the art person understand the scheme of the utility model better, the utility model is done further to specify below in conjunction with the accompanying drawing and the specific embodiment.
The specific embodiment is as shown in Figure 1.The related gel ink pen nib of this specific embodiment has the Pom made.Pom is a kind of engineering plastics of function admirable; Pom has hardness, intensity and the rigidity of metalloid; Good self lubricity, good fatigue durability are all arranged in very wide temperature and humidity scope, and springiness, it also has chemical-resistant preferably in addition.The Pom material to be to be lower than the cost of other many engineering plastics, substituting some traditionally by market that metal captured.
The related gel ink pen nib of this specific embodiment comprises tube connector 1 and nib 2.Tube connector 1 is what be wholely set with nib 2 in this embodiment.When the written printing ink pipe with gel ink pen of the neutrality in the utility model was installed, the tube connector 1 of this neutrality nib was held insertion and fixing from the following China ink of printing ink pipe, plays the effect that connects printing ink pipe and nib.
Nib is a hollow in this embodiment, and hollow space is an oil ink passage 3.Oil ink passage 3 is used for conducting nib 2 and the printing ink pipe that said nib is connected, and makes printing ink flow to the tip of nib head 21 through oil ink passage 3 from the printing ink pipe.
Said nib 2 is bullet shaped, is made up of nib head 21 and nib afterbody 22.Nib head 21 is cones of a hollow, and nib afterbody 22 is cylinders of a hollow, and the maximum cross section diameter of nib head 21 cones is identical with nib afterbody 22 cylindrical cross-sectional diameters, and they are wholely set.Oil ink passage nib head 21 in the said nib is provided with ball seat near the position at tip.Like Fig. 2 is the ball socket structure sketch map of this embodiment.The bottom of ball seat is the ink tank 23 that is five-pointed star shape hole.Printing ink flows to ball 24 from the oil ink passage 3 of nib through the hole of ink tank 23.The rim of a bowl of ball seat is the closing in shape, encases ball and makes the ball difficult drop-off.The nib material is the mixing Pom material that lubricant effect is arranged, and ball can freely be rolled in ball seat.Because ball can freely roll in ball seat, ball and the frictional force drive ball write between the thing roll in ball seat when writing, and ball will flow to its printing ink and constantly take out of, write on the thing thereby printing ink is transferred to.
The external diameter of said tube connector 1 is less than the external diameter of nib 2 near the nib afterbody 22 at tube connector place, and tube connector 1 is used for fixing an end that is installed in China ink under the printing ink pipe.Said tube connector 1 has chamfering 11 at the end away from nib that is fit into the printing ink pipe, and the tube connector 1 that chamfering 11 makes nib is in that to be fit into printing ink Guan Shigeng easy.
The above-described specific embodiment is a kind of preferred implementation of the utility model.
Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
