Abstract
The utility model discloses a nib of a gel pen, which comprises a metal ball seat and a ball bead. The top end of the metal ball seat is provided with a cavity; the ball bead is arranged in the cavity; and the ball bead partially stretches out of the cavity. The nib of the gel pen is characterized in that a jacking spring is arranged in the metal ball seat, and jacks the ball bead; the nib of the gel pen has the advantages that the jacking spring jacks the ball bead; when the gel pen is not used, no clearance exists between the ball bead and the top end of the metal ball seat; therefore, even if the gel pen is reversed for a long time or the gel pen is beaten by strength, air can not enter printing ink so as to prevent the normal writing of the gel pen from being influenced. During the gel pen is used forwriting, a downward acting force is generated by a human hand to the gel pen to lead the ball bead of the nip to generate a reacting force to the jacking spring and generate a clearance between the ball bead and the top end of the metal ball seat; therefore, the printing ink flows out under the rotation of the ball bead.
Description
Technical field
The utility model relates to a kind of nib, especially relates to a kind of Neutral writing ink pen nib.
Background technology
Nib is the vitals in the Neutral writing ink pen, and the nib of Neutral writing ink pen comprises Metal Ball pedestal and ball, and the top of Metal Ball pedestal is provided with a cavity that ball is installed, and the Metal Ball pedestal communicates with the printing ink pipe.The part of ball is stretched out cavity outside, and ball can do moving of certain amplitude in cavity, keeps certain interval between the top of ball and Metal Ball pedestal, can flow out swimmingly with supplied ink.When writing, printing ink flow in the cavity under the effect of gravity, and the spheroid of rolling is write the printing ink in the cavity on paper by the gap.There are the following problems for the Neutral writing ink pen nib of this kind structure: in storage or use, because of unconscious operation, Neutral writing ink pen handstand time ratio is more of a specified duration, the interior printing ink of this moment printing ink pipe and Metal Ball pedestal flows backwards under the gravity effect, air can enter in the gap between ball and the Metal Ball pedestal top simultaneously, air makes the printing ink cutout, causes and can't normally write.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Neutral writing ink pen nib of avoiding air to enter printing ink.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Neutral writing ink pen nib, comprise Metal Ball pedestal and ball, the top of described Metal Ball pedestal is provided with a cavity, described ball is positioned at described cavity, ball partly stretches out described cavity, in the Metal Ball pedestal top pressure spring is set, described top pressure spring withstands described ball.
Described cavity comprises cylindrical inner chamber and conical internal cavity, and described conical internal cavity is arranged on the rear end of described cylindrical inner chamber, and the angle between described cylindrical inner chamber wall and the described conical internal cavity wall is 125 degree～135 degree.
Angle between described cylindrical inner chamber wall and the described conical internal cavity wall is 130 degree.
Described Metal Ball pedestal is provided with oil storage tank, and described oil storage tank communicates with described cavity.
Described Metal Ball pedestal rear end is provided with annular protrusion, and described top pressure spring is arranged between annular protrusion and the described ball.
Described oil storage tank is 4, and described oil storage tank is ring-like to be evenly distributed in the Metal Ball pedestal.
Compared with prior art, advantage of the present utility model is that top pressure spring withstands ball, when the Neutral writing ink pen does not use, there is not the gap between ball and the Metal Ball pedestal top, even stand upside down for a long time or firmly beat the Neutral writing ink pen, do not have air yet and enter into printing ink, avoid influencing normally writing of Neutral writing ink pen.When writing, staff produces a downward active force to neutral pen, makes the ball of nib produce a reaction force to top pressure spring, produces the gap between ball and the Metal Ball pedestal top, and printing ink flows out under the rotation of ball.
Traditional written cylindrical inner chamber wall and the angle between the conical internal cavity wall be 120 the degree, 130 angle can make more printing ink in cavity, promptly ball is played lubricated effect, can make again write smooth and easy.
Being provided with of oil storage tank guaranteed fuel delivery, and be fuel-displaced more smooth and easy when writing.

Fig. 2 is the enlarged drawing of A in the utility model.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of Neutral writing ink pen nib comprises Metal Ball pedestal 1 and ball 2, and the top of Metal Ball pedestal 1 is provided with a cavity 3, and ball 2 is positioned at cavity 3, and ball 2 parts are stretched out cavity 3, and top pressure spring 4 is set in the Metal Ball pedestal 1, and top pressure spring 4 withstands ball 2.Cavity 3 comprises cylindrical inner chamber and conical internal cavity, and conical internal cavity is arranged on the rear end of cylindrical inner chamber, and the angle between cylindrical inner chamber wall and the conical internal cavity wall is 125 degree or 130 degree or 135 degree.
Metal Ball pedestal 1 is provided with a plurality of oil storage tanks 5, and a plurality of oil storage tanks 5 communicate with cavity 3.
Oil storage tank is 4, oil storage tank 5 ring-like being evenly distributed in the Metal Ball pedestal 1.
