The utility model is achieved through the following technical solutions:
A kind of gel ink pen improves structure, include storage ink tube and a nib, described nib is divided into stationary pipes and nib two parts, described storage ink tube matches with stationary pipes one end of nib, the internal diameter of the end that described storage ink tube cooperates with stationary pipes is complementary with the external diameter of this end of stationary pipes, described nib is for there being the perforation cavity structure, described cavity is different cylindrical of diameter, described stationary pipes matches the part external diameter less than the external diameter of part more than the stationary pipes with the storage ink tube, and it is conical that described nib profile is.
Described stationary pipes and nib are integrated setting, described nib end is provided with cavity, be provided with ball in the described cavity, described ball partly exposes outside the cavity, and described cavity bottom is porose to communicate with stationary pipes and nib, is provided with spring in described stationary pipes and the nib, described spring is pressed ball by the top, hole of cavity bottom, the spiral external diameter that described spring forms is identical, and described stationary pipes cavity is comprised of two different inner diameters, and nearly nib direction internal diameter is little in these two internal diameters.
As further improvement, two internal diameters are greater than nib part cavity internal diameter in the described stationary pipes cavity, and nib part cavity internal diameter is greater than the cavity bottom bore dia.
Described cavity is cylindrical.
The groove of inwardly giving prominence to that is positioned at same cross section is arranged on the described stationary pipes, and described groove is 3-4.
The beneficial effects of the utility model are:
Pass through the technical solution of the utility model, design to written inner chamber body, so that spring can remain on the same axis, having guaranteed that printing ink can't overflow can guarantee that also air does not enter nib section and prevents ink setting, and directly strengthens the hole of cavity rear end and do not need to process separately oil storage tank or oil storage hole again.
