Abstract
The invention discloses an improved needle tube type pen point which is connected with the front end of a pen holder. The improved needle tube type pen point is characterized by comprising a bead seat and a ball bead, wherein the perimeter of the bead seat is smaller than that of the pen holder; a groove is formed at the top of the bead seat; a plurality of ink guiding grooves are arranged on the inner circumferential wall of the bead seat in the direction of a center shaft and form an annular ink storage area at the bead seat; and the ball bead is embedded into the groove. Compared with the traditional pen point with three ink guiding grooves, the invention has more ink guiding grooves with smaller ink guiding density, so that the ink feeding is smoother.
Description
Technical field
The present invention relates to a kind of improved needle tube type pen point.
Background technology
As shown in Figure 1, the needle tubing pen is the very high class pen of possession share in the market.The difficult point of making needle tubing pen nib is that the structure that its front end is held pearl is to use the mode (only having provided two points 11 and 12 in the diagram) of making a call at 3 or making a call at 4.But accurately average, very difficult because the needle-tube pen-point ledge got ready 10 needs, and its core 13 be hollow, adds the influence that can be subjected to destabilizing factor man-hour in turning, causes manufacturing very difficult, it is inhomogeneous to cause writing lines.
Summary of the invention
At the problems referred to above, the present invention proposes a kind ofly not adopt the mode of getting ready, and utilizes the manufacture craft of draw technology, directly form the holder pearl after, ball is no longer needed by making a call to 3 or make a call to 4 points.
A kind of improved needle tube type pen point of the present invention, the front end that is arranged on a penholder links to each other, it is characterized in that, comprise: a pearl seat, its week directly is smaller than described penholder, form a groove at described pearl seat top, offer several ink guide tanks with central axis direction on the internal perisporium of described pearl seat, described ink guide tank forms the storage ink-covered area of a ring-type at described pearl seat place; One ball is embedded in described groove.
Reasonable is that described ink guide tank comprises 5 or 6.
Because the present invention need not make a call to or 4 points at 3, original turning instability, and get even problem rambunctious ready and all do not exist, and because this technology can change five grooves into by the ink outlet trough of original four grooves or three-flute, use the uniformity of China ink and write feel and all be significantly improved.
Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, from the detailed description to the inventive method, above-mentioned and other purposes of the present invention, feature and advantage will be apparent.
Fig. 1 is a perspective view of the prior art;
Fig. 2 is a perspective view of the present invention;
Fig. 3 is the cutaway view of structure among Fig. 2;
Fig. 4 is the upward view of structure among Fig. 2.
The specific embodiment
See also shown in Fig. 2-3, this needle tube type pen point has also adopted draw structure, and the Zhou Jing of the pearl seat 22 of front end is smaller than the penholder 21 of rear end, forms a groove 23 at the top of pearl seat 22, in order to hold ball.More traditional Fig. 1 structure difference part is Fig. 3, on pearl seat 22, do not adopt with perforation structure and form ink guide tank, but on the internal perisporium of pearl seat 22 with central axis direction, directly offer five ink guide tanks 24, can know from the upward view of Fig. 4 and see this five ink guide tanks 24.
The present invention more originally utilized the method for getting ready to hold the way of ball and manufacturing oil groove, because the area of needle tubing is too small, can not get 5 points, utilized draw technology to hold ball now, can make a call to 5 grooves, even 6 grooves.
Not only three ink guide tanks than original are quantitatively more owing to a plurality of ink guide tanks, and it is littler to lead black density, and ink supply is more smooth and easy; Like this, five ink guide tanks 24 form the storage ink-covered area of a ring-type at pearl seat 22 places, and it is more even that printing ink is coated on the ball; Because it is more even that printing ink is coated on the ball, make cooperate between ball and the pearl seat 22 more sliding suitable.
More than all embodiment only for the explanation the present invention usefulness, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present invention and should be limited by each claim.
Claims (2)
