Abstract

The utility model discloses an ink press type automatic fountain pen, which does not need to take off a pen cap but sucks ink automatically, composed of a pen head and a pen pipe. The utility model has the structure that a suction pipe with a piston barrel, is arranged in the pen pipe; a glass ball is arranged at the connection position between the piston barrel and the suction pipe fixed to a fixed seat of the suction pipe which is arranged under the pen pipe; the suction pipe is inserted into a pen tongue of a suction groove of the pen head, a piston rod with a spring is extended into the piston barrel, and the top of the spring is covered by a press cap. When the ink is sucked, the press cap is pressed, and then, the press cap is loosened, so the ink is sucked into the pen pipe. The utility model has the advantages of simple structure and convenient use.

Description

Automatic press type ink suction fountain pen

The utility model relates to a kind of pen, especially a kind of pen that need not to press barrel and absorb water automatically.

At present, generally the pen of Shi Yonging mostly is that a rubber suction courage is housed in written back, after the ink in the suction courage uses up, takes off the pen cap of outside, absorbs water with hand extruding suction courage, does make dirty easily finger and file like this, and is extremely inconvenient.

The purpose of this utility model just provides a kind of pen that need not to take off the pen cap and absorb water automatically.

The utility model can be realized by following scheme.

The utility model comprises nib and shaft of a writing brush two parts.There is the suction hose of a band piston cylinder shaft of a writing brush the inside, and a ballotini is arranged between piston cylinder and the suction hose, and a suction hose holder is arranged at shaft of a writing brush bottom.Leaking hole is arranged on the holder, and piston cylinder is with a piston retainer ring outward, and leaking hole is also arranged in the retainer ring, and there is the piston rod of a band spring piston cylinder the inside.The piston rod holder is housed between piston rod and the spring.Cover piston rod at shaft of a writing brush top with gland.Nib and the shaft of a writing brush be with being threaded, and the suction hose in the shaft of a writing brush inserts in the pick trough of the proposition inside written.When needs blot, as long as pin gland, piston rod propelling piston tube is got rid of the air of piston cylinder the inside, ballotini stops the piston nozzle simultaneously, when loosening gland, and recoil of spring, outside pressure is compressed into piston cylinder to ink, several times circulation, the ink of piston cylinder enters the shaft of a writing brush, and then enters the nib use.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

The utility model comprises nib 1, the shaft of a writing brush 2 two parts.There is the suction hose 4 of a band piston cylinder 3 shaft of a writing brush 2 the insides, piston cylinder 3 has a glass marble 5 with suction hose 4 connecting places, suction hose holder 6 is arranged at the bottom of the shaft of a writing brush 2, piston cylinder 3 usefulness piston retainer rings 7 are fixing, retainer ring 7 has small opening, and piston rod 8 inserts piston cylinder 3 the insides, fixes a spring 9 on the piston rod 8, skew about piston rod 8 usefulness piston rod holders 10 are fixed and do not understood can only move up and down.Piston rod 8 is glanded 11 and covers, horizontal protrusion 12 is arranged at gland 11 bottoms, this horizontal protrusion is on same circumference, its radius of a circle is slightly less than the radius of the shaft of a writing brush 2 inwalls, one horizontal plane of the shaft of a writing brush 2 inwalls also have one with the gland 11 bottom protrusions 12 identical protrusion 13 that distributes, this protrusion 13 has only 1/3rd of gland 11 height apart from the height at the shaft of a writing brush 2 tops, and the outside of the shaft of a writing brush 2 also is provided with visual water level window 18.Nib 1 comprises nib 14, proposition 15 and nib seat 16, nib seat 16 and 6 threaded connections of suction hose holder.17 li of the pick trough of suction hose 4 insertion propositions 15, when needing suction, the position of adjusting gland is just staggered its horizontal protrusion 12 and the horizontal protrusion 13 of shaft of a writing brush the inside, press a lower cover 11 with thumb, piston rod 8 stretches into the air that piston cylinder 3 is got rid of the inside, glass marble 5 bottles up the piston nozzle simultaneously, loosen thumb again, spring 9 resiliences, piston rod 8 rises, and outside pressure is pressed into piston cylinder 3 to ink, reciprocation cycle, enter the shaft of a writing brush 2 bottoms up to ink,, enter nib again by the small opening of suction hose holder.The utility model is simple in structure, and is easy to use.
