Description

Pneumatic pen

Technical field

The utility model relates to a kind of Pneumatic pen.

Background technology

At present, common pen core ink utilization rate is lower, the frequent situation occurring also having ink but cannot carry out writing because air pressure is not enough in pipe; Now can only change pen core, increase the consumption of pen core virtually, waste a large amount of ink.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides the Pneumatic pen that a kind of ink utilization rate is high.

The purpose of this utility model is achieved in that a kind of Pneumatic pen, described Pneumatic pen includes the shaft of a writing brush, one piston is installed in the described shaft of a writing brush, the shaft of a writing brush is separated into two parts by described piston, and piston is to the cavity of the nib portion formation one accommodation ink of the shaft of a writing brush, a trailer card for the described shaft of a writing brush is equipped with a thumb wheel, described thumb wheel revolves and is equipped with a screwed pipe, and one of this screwed pipe section is connected to piston, and the hollow tube of screwed pipe is connected with the cavity holding ink in the shaft of a writing brush.

The utility model Pneumatic pen, the afterbody of the described shaft of a writing brush is provided with an annular groove, described thumb wheel is provided with the annular flange be embedded in this annular groove.

The utility model Pneumatic pen, described thumb wheel is connected with a shaft of a writing brush extension, and above-mentioned screwed pipe is placed in this shaft of a writing brush extension, and the material of this shaft of a writing brush extension is transparent plastic.

The utility model Pneumatic pen, described shaft of a writing brush extension is provided with a link plate.

Compared with prior art, the beneficial effects of the utility model are:

The utility model can regulate the ink in cavity by thumb wheel, thus make user can use up last oil dripping ink easily, improve the utilization rate of ink, reduce the use cost of user, and save a large amount of ink, meet advocating of conservation-minded society.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model Pneumatic pen.

Fig. 2 is the shaft of a writing brush of the utility model Pneumatic pen and the partial structurtes schematic diagram of thumb wheel junction.

Wherein:

The shaft of a writing brush 1, piston 2, screwed pipe 3, thumb wheel 4;

Annular groove 1.1;

Annular flange 4.1;

Shaft of a writing brush extension 101, link plate 102.

Detailed description of the invention

See Fig. 1 and Fig. 2, a kind of Pneumatic pen that the utility model relates to, described Pneumatic pen includes the shaft of a writing brush 1, be provided with a piston 2 in the described shaft of a writing brush 1, the shaft of a writing brush 1 is separated into two parts by described piston 2, and the nib portion of piston 2 to the shaft of a writing brush 1 forms the cavity that holds ink, a trailer card for the described shaft of a writing brush 1 is equipped with a thumb wheel 4, described thumb wheel 4 revolves and is equipped with a screwed pipe 3, and one of this screwed pipe 3 section is connected to piston 2, and the hollow tube of screwed pipe 3 is connected with the cavity holding ink in the shaft of a writing brush 1;

Preferably, the afterbody of the described shaft of a writing brush 1 is provided with an annular groove 1.1, described thumb wheel 4 is provided with the annular flange 4.1 be embedded in this annular groove 1.1, thus make to stir thumb wheel 4 when rotating, thumb wheel 4 remains unchanged with the relative position of the shaft of a writing brush 1, and screwed pipe 3 now can be driven to move to nib place, thus causes the ink held in the cavity of ink to have part to enter in screwed pipe 3, what add ink writes pressure, improves its utilization rate;

Simultaneously, in order to increase the intuitive to ink use amount, described thumb wheel 4 is connected with a shaft of a writing brush extension 101, and above-mentioned screwed pipe 3 is placed in this shaft of a writing brush extension 101, the material of this shaft of a writing brush extension 101 is transparent plastic, be convenient to the ink surplus that writer observes riffled tube 3 intuitively like this, thus it can be adjusted in time; And described shaft of a writing brush extension 101 is provided with a link plate 102, facilitate writer by the utility model Pneumatic pen not in pocket etc. place carry;

After adopting the utility model, can be regulated by the ink in thumb wheel 4 pairs of cavitys, thus make user can use up last oil dripping ink easily, improve the utilization rate of ink, reduce the use cost of user, and saved a large amount of ink, meet advocating of conservation-minded society.
