Abstract

The piston type fountain pen features that the small end holes of two pen holders are directly filled with pen head, and the large end pen holder cavity is the ink containing cavity of the pen and the acting cylinder matched with the two end pipes of the H-shaped piston. "H" type piston is at the sealed penholder chamber of penholder main aspects and does relative motion in the axial, changes the intracavity volume, produces the negative pressure, accomplishes the purpose of absorbing water and retaining, behind the intracavity air of discharging, but the pen normal use, the cap of the pen of cover matching closes as an organic wholely with the tip of pen, so the structure with make simple very much, easy operation, the chamber capacity is big, can observe, a pen is multi-purpose: more convenience is brought to carrying and writing.

Description

Piston type fountain pen

The present invention relates to a kind of different solutions that in two penholder chambeies, back and forth aspirates, satisfy " H " type piston type fountain pen that different nibs are write requirement.

In being permitted the multipurpose pencil occasion, people wish to use easily different solution to satisfy certain Writing-painting needs, as two coloured gold pens, and big or small Pen for handwriting, crayon or the like, and a known series products is difficult to satisfy ideally these requirements at present.

Task of the present invention provides a kind of rational in infrastructure, can satisfy multipurpose " H " the type piston type fountain pen that different Writing-paintings etc. require.

Its solution is: it is cylinder sleeve with the penholder, and " H " type pipe is a piston, loads onto nib in the little stomidium of penholder." H " type piston is put in the big end of the two penholders chamber with the sealing of penholder chamber respectively and is axially being done relative motion, increases in the chamber molten long-pendingly, produces negative pressure, reaches to absorb water and the purpose of written Writing-painting is satisfied in retaining.

The present invention is because put into the nib of difference in functionality at the penholder small end; " H " type piston directly is sealed and matched with two penholder chambeies, slides mutually to change the purpose that pen suction and retaining are finished in molten chamber; It is one that the cap for brush that cover is joined cooperates with the end of pen.So structure and make simply especially, easy to operate, a chamber water solubilization is big and can observe, and usefulness more than one is given to carry and write and brought more convenience.

Below in conjunction with accompanying drawing this pen is elaborated.

Accompanying drawing 1 is this concrete structure figure.

Accompanying drawing has been enumerated this embodiment, but does not have uniqueness.

This structure comprises " H " type piston (1), penholder (2), and the microcephaly of (5) puts into nib (3) and (6) and cover and goes up the cap for brush (4) and (7), and the cap for brush that cover is joined is integrated with the end of pen.The interior sealing of big stomidium of penholder (2) and (5) put at conduit position, " H " type piston (1) two ends respectively, is slidingly matched.Cooperate normal position with 1 expression operation completed " H " type piston with penholder.

Unloading the cap for brush (4) is enclosed within on the cap for brush (7), nib (3) is immersed in the sucked liquid, hold penholder (2), pulling " H " type piston (1) makes the piston at position, the left side be subjected to displacement in axial and penholder chamber, molten chamber increases, and produces negative pressure, and liquid is sucked in the chamber: nib up, penholder (2) is made reseting movement in opposite directions with piston, promptly finishes stylographic pump up water operation in the discharge side behind the air.With the liquid that will be filled other purposes in same method of operating " H " type piston right-hand member and the chamber that penholder (5) cooperates, " H " type piston type fountain pen can normally use.

Claims

1, piston type fountain pen is characterized in that direct nib (3) and (6) of putting into difference in functionality in penholder (2), (5) little stomidium; Penholder (2), the big end inner chamber of (5) are the molten water cavity of pen and the acting cylinder that cooperates with " H " type piston (1) two ends conduit; " H " type piston (1) is respectively charged in the big end chamber of penholder (2) and (5) sealing and does relative motion, and is molten long-pending to change in the chamber, produces negative pressure, makes the quantitative solution of the difference inspiration chamber in, behind the air, finished the purpose of suction and retaining in discharge side; The cap for brush (4) can entangle the cap for brush (7) and can fit in one with the end of pen.
