Abstract
The utility model discloses a ball pen point with an oversized ball diameter, which comprises a ball seat and a ball bead. A ball cavity is formed in one end of the ball seat, an ink channel is arranged at the other end of the ball seat, the ball cavity and the ink channel are communicated, and the ball bead is accommodated in the ball cavity. The ball pen point is characterized in that the ball diameter of the ball bead ranges from 1.2mm to 1.4mm; the narrow opening angle of the ball seat ranges from 68 degrees to 72 degrees; the narrow opening shape of the ball bead in the ball seat is required to be flat and smooth, and the tightness degree of the matching between the ball seat and the ball bead is appropriate; the narrow opening angle of a ball seat of an ordinary ball pen ranges from 68 degrees to 72 degrees, and by means of a contrast test of various narrow opening process schemes, the narrow opening angle is finally determined to be from 56 degrees to 60 degrees, so that the radial clearance is reduced to effectively control the ink outlet channel, and the condition of ink leakage during writing is reduced.
Description
Technical field
The utility model relates to the ball pen technical field, more specifically says a kind of super large sphere diameter ball-pen point.
Background technology
As everyone knows, the ball specification that ball pen adopts generally has five kinds of diameter 0.5mm, diameter 0.6mm, diameter 0.7mm, diameter 0.8mm, diameter 1.0mm, the domestic market is take diameter 0.7mm ball as main, and the ball pen that outlet is produced with diameter 0.8mm, diameter 1.0mm ball is in the majority.
Just mentioned a kind of superfine smooth pen point in the applicant patent ZL200820085691 in the early time, its ball specification adopts diameter 0.4mm, belongs to thinner, and it is in order to satisfy special requirement, in general the larger handwriting of ball pen sphere diameter is thicker, writes feel more comfortable.But, along with the increase of sphere diameter, the increase of amount out of ink and dewdrop face, ball pen can produce bleed and the phenomenon such as the first stroke of a Chinese character is bad.
The utility model content
The purpose of this utility model is to overcome the large easily bleed of prior art ball pen sphere diameter and the defective of the phenomenon such as the first stroke of a Chinese character is bad, provides a kind of and is furnished with the super large ball but writes smooth and uniform super large sphere diameter ball-pen point out of ink.
In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of super large sphere diameter ball-pen point, comprise ball seat and ball, and an end of described ball seat offers a ball chamber, the other end offers an oil ink passage, and described oil ink passage and described ball chamber are conducted; Described ball is placed in described ball chamber; It is characterized in that, the sphere diameter scope of described ball is at 1.2mm to 1.4mm; The closing in angular range of described ball seat is spent to 72 at 68 degree.
The shape relation that the position of ball in ball seat, ball seat limit encase ball is write feel and bleed performance to pen core.In ball seat, the closing in shape need of ball is smooth, bright and clean, and ball seat coordinates degree of tightness suitable with ball.The closing in angle of general ball pen ball seat be 68 degree to 72 degree, in the contrast test of multiple bottling technique scheme, determined that finally closing in angle 56 spends to dwindle radial clearance to degree 60 and effectively control out ink passage, reduce the generation of writing lines bleed mark.
As preferably, the fit clearance scope in described ball and described ball chamber is at 0.011mm to 0.013mm.
As preferably, be provided with oil groove on the wall of described ball chamber, described oil groove and described oil ink passage are conducted.
As preferably, the groove width scope of described oil groove is at 0.15 mm to 0.16mm, and the groove depth scope of oil groove is more than or equal to 0.30mm.
Suitably amplify the fit clearance of ball chamber and ball, and oil groove width and the degree of depth, increasing amount out of ink, raising pen core fluent writing weares and teares to some extent and also the passage of oil groove and annular groove can be cut off along with the ball chamber avoiding, and affects writing quality.
Beneficial effect: (gap in ball and ball chamber is 0.012mm owing to having improved ball socket structure; Oil groove width 0.15-0.16mm; Groove depth〉0.30mm; Ball seat closing in angle is 56-60 °.), and make its Proper Match, just write performance: 200mm is interior out of ink normal to have guaranteed super large sphere diameter ball-pen point; Marking lengths: 〉=600m; Emit oil stain :≤10.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-ball seat, 2-ball, 3-ball chamber, 4-oil ink passage, 5-oil groove.
The specific embodiment
Be easy to understand understanding in order to make technological means of the present utility model, creation characteristic and to reach purpose, further set forth the utility model below in conjunction with specific embodiment.
