Embodiment Construction

[0009] refer to figure 1 As shown, the sphere of the soft magnetic ball 1 is made of soft magnetic materials containing iron, nickel, and cobalt; the external permanent magnetic ring 3 or the internal permanent magnetic ring 4 is made of NdFeB or other high-performance hard magnetic materials. The permanent magnet on the nib can be made into various shapes, and the combination form of the nib and the permanent magnet ring is optimized: the outer permanent magnet ring 3 is selected for the smaller diameter of the nib; the inner permanent magnet ring 4 is selected for the larger diameter of the nib. After the soft magnetic ball 1 and the nib 2 are assembled, the soft magnetic ball 1 is limited in the nib body by the magnetic force generated by the permanent magnetic ring set on the nib 2, so as to avoid the ball falling and ink leakage after the ballpoint pen is worn and worn, and the ballpoint pen is more stable. Durable.

Abstract

The invention relates to a magnetic ball pen tip in the field of stationery. The magnetic ball pen tip comprises a ball and a pen nib and is characterized in that a permanent magnetic ring is arranged on the rear pen nib of the ball specifically comprising a soft magnet. The ball and the pen nib are matched in a magnetic attraction mode to prevent the ball from disengaging and prevent ink from leaking.

Description

[0001] technical field [0002] The invention relates to a magnetic ballpoint pen head in the field of stationery. Background technique [0003] In the known ballpoint pen tip, the ball and the nib have high matching precision requirements, the ball is easy to fall off after being worn out, the useful life is short, and it is difficult to match the nib and the ink. Contents of the invention [0004] The technical problem to be solved by the present invention is: to transform the ordinary ballpoint pen head into a magnetic ballpoint pen head, to prevent the falling off of the ball point and the leakage of ink inside the pen point by using the magnetic attraction, and to increase the length of the writing line. [0005] The technical scheme of the present invention is that the magnetic ballpoint pen head includes a ball and a pen point, and the feature is that a permanent magnetic ring is arranged on the pen point at the rear side of the ball ball specifically containing...
