Abstract
The utility model relates to an ultrathin smooth pen head which can ensure smooth writing and even ink discharge. The pen head comprises a ball rest body, one end of the ball seat body is provided with a ball seat, a ball having a matching sphere diameter with the ball seat is embedded in the ball seat, the other end of the ball seat body is provided with a middle oil hole, the ball seat is communicated with the middle oil hole through an oil pore. The pen head is characterized in that the sphere diameter of the ball is 0.4 mm, and the bottom of the ball seat is provided with a ball seat angle which is from 100 degrees to 115 degrees. The bass seat angle can be set from 110 degrees to 115 degrees by changing the angle of the ball seat angle, the ink supplying efficiency of the ball seat is greatly improved, so that the refill made of small sphere diameter ball can write fluently and smoothly with even ink discharge.
Description
Technical field
The utility model relates to a kind of ball pen, especially relate to a kind of write smooth and easy, go out China ink uniformly superfine type along sliding nib.
Background technology
The pen core of ball pen normally is made up of nib, China ink pipe and printing ink, wherein nib generally includes a ball seat body, one end of ball seat body is offered a ball seat, the ball seat angle that the bottom of ball seat is provided with, be embedded with the associated ball of sphere diameter in the ball seat, the other end of ball seat body offers middle oilhole, also is provided with straight trough and little oilhole in the ball seat body.At present, the ball specification that homemade oiliness ball pen adopts generally can be divided into carefully (φ 0.5mm), in (φ 0.7mm, φ 0.8mm), (φ 1.0mm) three kinds slightly, at these sphere diameters is in 0.5mm～1.0mm nib, and the ball seat angle of nib is all adopted 90 °, and straight trough length is made as 0.15mm usually.The thickness of the size decision handwriting of sphere diameter, according to the Chinese-character writing characteristics, sphere diameter is more suitable for personnel's such as student, financial accounting instructions for use less than the ball pen of 0.5mm (as 0.4mm), but along with dwindling of sphere diameter, can increase the difficulty of processing of ball seat greatly, and if to adopt with sphere diameter be the ball socket structure of the above nib of 0.5mm, the ink supply usefulness of ball seat is relatively poor, the cunning that can have some setbacks when produced pen core is write, even produce and scrape the paper phenomenon.
The utility model content
The utility model mainly is that to solve the existing in prior technology sphere diameter be that the pen core of 0.4mm is write the cunning that has some setbacks, and can produce the technical problem of scraping paper phenomenon etc., provide a kind of increased the ball seat angle make write smooth and easy, go out China ink uniformly superfine type along sliding nib.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of superfine type is along sliding nib, comprise the ball seat body, one end of described ball seat body is offered a ball seat, be embedded with the associated ball of sphere diameter in the ball seat, the other end of ball seat body offers middle oilhole, is connected by little oilhole between ball seat and the middle oilhole, it is characterized in that: the sphere diameter of ball is 0.4mm, the bottom of described ball seat is provided with the ball seat angle, and the ball seat angle is 110 °～115 °.By changing the angle at ball seat angle, the ball seat angle is set to 110 °～115 °, has improved the ink supply usefulness of ball seat greatly, and that the pen core that makes the ball of little sphere diameter make is write is comparatively smooth, along sliding, goes out China ink evenly.
As preferably, described little oilhole is provided with straight trough, and straight trough connects with ball seat and middle oilhole respectively.
As preferably, the length of described straight trough is at least 0.25mm.Little oilhole is provided with respectively the straight trough that connects with ball seat and middle oilhole, and the length of straight trough helps improving the ink supply usefulness of ball seat greater than 0.25mm.
Therefore, the utility model compared with prior art, the ball seat angle is set to 110 °～115 °, the length of straight trough has improved the ink supply usefulness of ball seat greatly greater than 0.25mm, that the pen core that makes the ball of little sphere diameter make is write is comparatively smooth, along sliding.
Description of drawings
Accompanying drawing 1 is the cutaway view of a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: see accompanying drawing 1, a kind of superfine type is along sliding nib, comprise ball seat body 1, one end of described ball seat body 1 is offered a ball seat 2, is embedded with the associated ball 3 of sphere diameter in the ball seat 2, and the other end of ball seat body 1 offers middle oilhole 4, be connected by little oilhole 5 between ball seat 2 and the middle oilhole 4, the sphere diameter of ball 3 is 0.4mm, and the bottom of described ball seat 2 is provided with the ball seat angle, and the ball seat angle is 110 °.Little oilhole 5 is provided with straight trough 6, and straight trough 6 connects with ball seat 2 and middle oilhole 4 respectively; The length of straight trough 6 is 0.25mm.When writing, because the ball seat angle is 110 °, the length of straight trough 6 is 0.25mm, has improved the ink supply usefulness of ball seat 2 greatly, and that the pen core that makes the ball of little sphere diameter make is write is comparatively smooth, along sliding, goes out China ink evenly.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
Claims (3)
1. a superfine type is along sliding nib, comprise the ball seat body, one end of described ball seat body is offered a ball seat, be embedded with the associated ball of sphere diameter in the ball seat, the other end of ball seat body offers middle oilhole, is connected by little oilhole between ball seat and the middle oilhole, it is characterized in that: the sphere diameter of ball is 0.4mm, the bottom of described ball seat is provided with the ball seat angle, and the ball seat angle is 110～115 °.
2. superfine type according to claim 1 is along sliding nib, and it is characterized in that: described little oilhole is provided with straight trough, and straight trough connects with ball seat and middle oilhole respectively.
