Abstract
The tubular body of rod of this refill for ball-point pen charge of oil China ink is a helical form, and screw rod body is a ring-type, also can be tower shape or S shape.The body of rod of pen core is to decide the length of its spiral part and spiral radian thereof as required in manufacture process.Compare with prior art, utilize the loop bar of same length can increase the printing ink reserves of pen core, the useful life that has prolonged pen core greatly.
Description
The present invention relates to a kind of refill for ball-point pen, particularly a kind of screw rod body ball-pen refill.
The refill for ball-point pen that uses is the linear pattern body of rod substantially at present.At some in particular cases, as in some double-purpose pens,, have to shorten the body of rod length of refill for ball-point pen in order to guarantee the appearance design and the necessary technology index of pen.Like this, just reduce the ink volume capacity of pen core relatively, influenced the useful life and the setting-out length of ball pen.
Task of the present invention provides a kind of refill for ball-point pen, this refill for ball-point pen in overall limited straight length, the more printing ink of can packing into.
Its solution is: refill for ball-point pen adopts screw rod body to come the charge of oil China ink, the helical form of the tubular body of rod of this charge of oil China ink is a ring-type, also can be tower shape or S shape, and the body of rod of pen core be according to using needs to decide its spiral length and spiral radian thereof partly in manufacture process.
The present invention compares with prior art, and the present invention utilizes the loop bar of same length, but can increase the printing ink reserves of pen core greatly.
Further improvement of the present invention is to increase by an axostylus axostyle in the middle of the pen core screw rod body, and the pen core body of rod is rotated around axostylus axostyle.So not only increase the strength of pen core when writing, can also directly make a kind of novel ball-point pen of structure uniqueness.
Accompanying drawing has been described a specific embodiment of the present invention.
Accompanying drawing 1 is the side view of a kind of screw rod body ball-pen refill of the present invention.
Accompanying drawing 2 is profilographs of a kind of screw rod body ball-pen refill of the present invention.
With reference to Fig. 1: a kind of refill for ball-point pen of the present invention, it has and is used for the screw rod body (1) of charge of oil China ink, and its right side is a kind of common refill for ball-point pen in order to contrast.
Fig. 2: in the middle of the pen core screw rod body (1) axostylus axostyle (2) is arranged, the body of rod (1) rotates around axostylus axostyle (2).
