Abstract
The invention discloses a writing pen to which ink can be added repeatedly. The writing pen to which ink can be added repeatedly comprises a writing pen head, a pen head body, a pen rod body, a pen cap, an ink storage pipe, a piston in the ink storage pipe, a pen rod sealing cap and a pen head sealing cap, and is characterized in that the ink storage pipe is arranged in the pen rod body, the piston is arranged in the ink storage pipe, rubber sealing rings are arranged in inner thread connecting ports in two ends in the pen rod body respectively, one inner thread connecting port in the pen rod body is in butting connection with an outer thread connecting port of the pen rod sealing cap, the inner thread connecting port at the other end in the pen rod body is in butting connection with an outer thread connecting port of the pen head body, the pen head body is provided with a pen head connecting port used for installing the writing pen head, the pen head connecting port is communicated with an inner cavity of the pen head body, the inner cavity of the pen head body is communicated with the ink storage pipe, and the pen cap is provided with the pen head sealing cap matched with the writing pen head, so that the writing pen to which the ink can be added repeatedly is formed. The writing pen to which the ink can be added repeatedly has the advantages that when the ink in the ink storage pipe is used up, the pen head body is detached down, the ink storage pipe is filled with ink again, the pen head body is installed again, and finally the ink pen can be used normally. The writing pen to which the ink can be added repeatedly is simple in structure, smooth in writing, durable and capable of replacing various writing pens such as a disposable gel pen, a whiteboard pen, a mark pen, an art pen and a pen with defects, and becomes a novel replaceable writing pen which is environmentally friendly, cheap and durable.
Description
technical field [0001] The invention relates to a writing pen capable of refilling ink, in particular, it belongs to the technical field of using an ink storage tube capable of refilling ink to directly supply ink to the tip of the writing pen, which effectively improves the writing time and the writing time of the writing pen. service life. Background technique [0002] Ink pens are the most used writing tools for people. In particular, neutral ink pens are favored by people due to their smooth writing, convenient use, and low price, and they have become the main product in the writing pen market. [0003] The advantage of the gel ink pen is that it is easy to carry, generally does not leak, is relatively clean, and is suitable for fast writing, and it is more convenient to change the refill. However, due to reasons such as low price, a large amount of neutral ink pens are discarded with the pen holder and the pen core at random after the pen core is used up, causing grea...
