CN202038034U - Pen refill capable of being reused - Google Patents

Abstract

The utility model discloses a pen refill capable of being reused, which belongs to a writing or drawing article, and particularly relates to a pen refill which is used for various writing pens. The pen refill capable of being reused is characterized in that a front end of a pen refill cylinder is provided with a dismountable pen point; cylinder wall on the top of the pen refill cylinder is provided with a round hole; a piston is arranged in the cylinder; and a string tied on the piston is connected to a circular ring by the round hole of the cylinder wall of the pen refill. The pen refill has the beneficial effect that the piston naturally falls under the action of atmospheric pressure along with the phenomenon that ink in the pen refill cylinder reduces when the pen refill is used. When the ink is used up, the pen point is removed, the pen refill cylinder extends into a container for containing the ink, the circular ring is pulled, the pen refill cylinder is gradually filled with the ink along with the raise of the piston, then the pen point is installed, and thus the pen refill can be reused.

Description

A kind of pen core that can be recycled

Technical field

The utility model belongs to be write or drawing article, the pen core that particularly various writing pens use.

Background technology

Various writing pens are the most frequently used writing implements of people, and the pen core of general writing pen all is disposable, after an oil uses up in the pen core, have just thrown away, and have caused the waste of resource, have polluted environment.

The utility model content

For the deficiency that the pen core that overcomes general writing pen can not reuse, the purpose of this utility model provides a kind of pen core that can be recycled, and after this pen core that can be recycled can make people an oil uses up in the pen core tube, is filled an oil and recycles.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of pen core that can be recycled, it is characterized in that: the pen core tube front end dismountable nib is housed, pen core tube top barrel is provided with circular hole, in the tube piston is housed, the circular hole of cord by the pen core barrel that ties up on the piston is connected on the annulus.

The beneficial effects of the utility model are in use to reduce along with the pen of pen core tube is oily, piston falls under the atmospheric pressure effect naturally, oil unloads nib when using up, the pen core tube is stretched into the container of containing pen oil, the pulling annulus, along with a piston rising oil progressively is full of the pen core tube, load onto nib then, pen core can be reused.
