Abstract

The utility model discloses a ball pen point with uniform ink output, which comprises a ball base and a ball. The inside of the ball base is provided with capillary bores and ball base bores. A step bore having the same shaft with the ball base bore is arranged between the ball base bore and the capillary bore. The ball pen point has uniform ink output and does not generate an ink leakage phenomenon.

Description

Go out the uniform ball pen head of China ink amount

The utility model relates to a kind of uniform ball pen head of China ink amount that goes out.

Ball pen is widely used writing implement, at present existing many kinds, just can be divided into the oiliness ball pen by it with black character, neutral ball pen, aqueous ballpoint pen, each user wishes to have one to write fluently, go out China ink ball pen uniformly, because this will help to improve the efficient of work and the quality of work, but people also may run into ropy ball pen when writing its all directions to go out China ink amount inhomogeneous and therefore produce the phenomenon of bleed, whether ball pen goes out the China ink amount evenly no doubt relevant with the quality of used printing ink or ink, but more important is to depend on whether the space between the ball and pearl seat hole is even in all directions on the ball pen head, just printing ink or the ink that enters pearl seat hole by pore should evenly distribute in all directions, and to make ball and pearl seat hole even in the space of all directions, people are conceived to improve the precision of each position processing of ball pen head usually, make great efforts to improve pore, both coaxial precision of pearl seat hole, but since they respectively by two cutters machine to guarantee strict coaxial be difficult, need a large amount of inputs of manpower and materials.

The purpose of this utility model is to propose a kind of uniform ball pen head of China ink amount that goes out, and it can be difficult for producing the bleed phenomenon so that ball pen goes out China ink evenly in all directions when writing.

The purpose of this utility model is achieved in that a kind of uniform ball pen head of China ink amount that goes out, and it includes pearl seat and ball, is provided with pore and pearl seat hole in pearl seat inside, be provided with between described pearl seat hole and the pore one with the coaxial step hole in pearl seat hole.

The utility model goes out the uniform ball pen head of China ink amount, since between pearl seat hole and pore, set up one with the coaxial step hole in pearl seat hole, and this step hole can adopt a boring cutter that is stage shape to be processed to form simultaneously with pearl seat hole, but thereby both coaxial precision of strict guarantee, even like this pore and pearl seat hole some deviation on the axis also just and the distribution relation of printing ink or ink all directions in pearl seat hole little.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is that the amplification master of pearl seat in the prior art looks cross-sectional schematic.

Fig. 2 is that the amplification master that the utility model goes out its pearl seat of the uniform ball pen head of China ink amount looks cross-sectional schematic.

Fig. 3 is the schematic diagram the pearl seat among Fig. 2 embeds ball in pearl seat hole after.

Fig. 4 is that the amplification master that the utility model goes out another kind of its pearl seat of embodiment of the uniform ball pen head of China ink amount looks cross-sectional schematic.

Referring to Fig. 1, be provided with pearl seat hole (4) and pore (3) in the pearl seat (1), pearl seat hole (4) communicates with pore (3), also being distributed with some grooves at the pore inwall communicates with the bottom in pearl seat hole (4), omitting groove does not in the drawings draw, the end face of common pearl seat (1), male cone (strobilus masculinus) and pearl seat hole (4) are by three finishing cutter of being installed in same station in a work step, and pore (3) is machined in two work steps by two cutters respectively owing to them with pearl seat hole (4), be difficult to guarantee its axiality, that is afraid of that axiality has the skew of 0.01mm also can confront the volume production life and seriously influences at its key position and for resembling the tiny like this product of ball pen head, in this enlarged diagram, because pore (3) and the deviation of pearl seat hole (4) on axial location, make the bottom in pearl seat hole (4) be the slope of different length in all directions, when ball is put into pearl seat hole (4), ball will not be to touch the bottom in pearl seat hole (4) equably and have significant directivity; Ball must be pressed through hammer and be embedded pearl seat hole (4), because hammering the resistance that ball is subjected to from bottom, pearl seat hole (4) when pressing into shape is that all directions are unbalanced, space between last like this its ball of the ball pen head of making and the pearl seat hole (4) also just has tangible directionality, when printing ink or ink when pore (3) enters pearl seat hole (4), will be created in certain direction storage China ink and measure how to store the few phenomenon of China ink amount in other direction, Here it is, and present ball pen goes out the black uneven major reason of measuring.

Referring to Fig. 2, ball pen head of the present utility model has been set up a step hole (5) coaxial with pearl seat hole (4) between pearl seat hole (4) and pore (3), this step hole (5) is processed by a boring cutter that is stage shape simultaneously with pearl seat hole (4), so both alignments of energy strict guarantee, thereby the bottom in pearl seat hole (4) also is the shape that the slope between pearl seat hole (4) and the step hole (5) is all directions equalization, and this step hole (5) is general only to need very shallow any just can play significant effect.

Referring to Fig. 3, when ball (2) was put into pearl seat hole (4), the bottom that ball (2) touches pearl seat hole (4) did not equably have directionality; Press through hammer, ball (2) embeds pearl seat hole (4), the suffered resistance from bottom, pearl seat hole (4) of ball (2) also is all directions equilibrium when hammer is pressed, space between last like this its ball of the ball pen head of making (2) and the pearl seat hole (4) does not have directionality yet, as long as step hole (5) guarantees coaxial with pearl seat hole (4), allow pore (3) and pearl seat hole (4) deviation slightly on axis, space between ball (2) and the pearl seat hole (4) still can keep all directions even, thereby guarantees that such ball pen head goes out the China ink amount and evenly is difficult for producing the bleed phenomenon.

Referring to Fig. 4, that is set up between pearl seat hole (4) and pore (3) is slightly different in shape with the step hole (5) among Fig. 2 with the coaxial step hole (5 ') in pearl seat hole (4), the inner surface of step hole among Fig. 2 (5) is the face of cylinder, the inner surface of step hole among this figure (5 ') is similar to spherical zone, these two kinds of step holes (5,5 ') all be that to make the bottom in pearl seat hole (4) also be the shape that slope between pearl seat hole (4) and the step hole (5 or 5 ') is all directions equalization, thereby after making ball embed pearl seat hole (4), ball is identical in the space of all directions with pearl seat hole (4), they have identical technical purpose and technique effect, all belong to scope of the present utility model.

Claims

1. one kind goes out the uniform ball pen head of China ink amount, it includes pearl seat (1) and ball (2), be provided with pore (3) and pearl seat hole (4) in pearl seat (1) inside, it is characterized in that: be provided with a step hole coaxial (5 or 5 ') between described pearl seat hole (4) and the pore (3) with pearl seat hole (4).
