Description

Pressing type large volume fountain pen

The utility model relates to the pen class in the cultural goods field.

Though it is of all kinds that existing pen has, be to adopt traditional type barrel, squash type water structure substantially.This pen feels that in use the barrel capacity is too little, such as in train of thought smoothness, has not had ink suddenly, and is unhappy really, and when doing work such as long writing record, ink bottle will be placed on the next door at any time, feels inconvenience deeply.Water filling work hell to pay during water filling, needs earlier penholder to be unloaded ink injection again, and then penholder is screwed on, and is easy to the hand of making dirty, also very loaded down with trivial details on the other hand trouble on the one hand.The part of this pen is many simultaneously, makes complicated.Based on above-mentioned situation, at the little problem of barrel capacity, existing Chinese patent CN2038449U has done improvement, problem at the water filling trouble, also there is Chinese patent GK87101047 to do improvement, but also do not have till settled the present to find to have a kind of technology thoroughly to solve the problems referred to above that existing pen exists.

The purpose of this utility model just provides the big capacity pen of a kind of push type, and it is big to have a barrel capacity, and water filling is convenient, and characteristic of simple structure has thoroughly solved the problem that existing pen exists.

Solution of the present utility model is, comprise the cap for brush, nib, proposition, blast pipe and penholder, wherein penholder is structure as a whole, the piston and the piston rod of band back-moving spring are housed in it, sealing ring is arranged on the piston, pen arm end is equipped with end cover, and its detailed content further describes as follows referring to accompanying drawing:

In technique scheme, the nib that is made of nib, proposition (2), blast pipe (3) is the structure of existing pen, the utility model becomes integrative-structure with penholder, simple in structure, the time processing moulding, and the inner chamber of penholder (4) is reservoir compartment, and the storage liquid measure of pen is heightened, and adopts the piston type fluid injection, promptly press piston rod (10), piston (8) moves downward, and penholder (4) inner chamber produces pressure, unclamps piston rod (10), back-moving spring (6) moves upward piston (8), black liquid is sucked in the penholder (4), very simple, convenient.Sealing ring (7) on the piston (8) guarantees the sealing of piston (8) and penholder (4) inner chamber, in case the ink in the penholder (4) leaches, the effect of end cap (9) is to prevent that piston (8) return under back-moving spring (6) effect from ejecting.

Piston rod of the present utility model (10) passes end cap (9) and adopts thread connection with piston (8), during water filling, turning piston rod (10) screws out it from piston (8), can press piston rod (10) up and down utilizes screw thread contact position drive piston (8) to carry out water filling, after filling with water, piston rod (10) is screwed in the piston (8), piston (8) is fixing, movable and ink is back-outed in penholder (4) inner chamber to prevent piston (8).Have a ring-shaped step (5) to be used for fixing back-moving spring (6) in penholder of the present utility model (4), like this, an end of back-moving spring (6) is against on the ring-shaped step (5), and the other end and piston (8) are fixing to get final product.

The big capacity pen of the push type that the utility model provides is simple in structure, easy to make, it as reservoir compartment, heightens the storage liquid measure penholder inner chamber, has reduced the number of times of perfusion ink, bring convenience to people, adopt piston type to push the fluid injection mode, easy to use, simple, also be not easy with ink in one's hands on, thoroughly overcome the problem that the pen of existing structure exists.Structure of the present utility model can also be used for other flexible pipe, watercolor pencil.

Concrete structure of the present utility model is provided by following example and accompanying drawing.

At first accompanying drawing is described:

Fig. 1 represents partial sectional view of the present utility model;

Fig. 2 represents STRUCTURE DECOMPOSITION figure of the present utility model.

According to embodiment shown in the drawings, by nib, proposition (2), the nib that blast pipe (3) constitutes is identical with existing pen, penholder (4) is an integral structure, be contained on the nib, one annular steps (5) is arranged in the penholder (4), one end of back-moving spring (6) is against on the annular steps (5), the other end piston (8) interior with being contained in penholder (4) is connected, two sealing rings (7) are housed on the piston (8), piston has screwed hole in (8), and penholder (4) end thread is connected with end cap (9), and piston rod (10) is the screw-type structure, the one end passes end cap (9) and piston (8) thread connection together, and the cap for brush (1) covers on nib and gets final product.

Claims (3)

1, the big capacity pen of a kind of push type, comprise the cap for brush, nib, proposition, blast pipe and penholder, feature of the present utility model is that penholder (4) is structure as a whole, the piston (8) and the piston rod (10) of band back-moving spring (6) are housed in it, sealing ring (7) is arranged on the piston (8), and end cap (9) is equipped with in penholder (4) end.

2, the big capacity pen of push type according to claim 1 is characterized in that piston rod (10) passes end cap (9) and adopts thread connection with piston (8).

3, the big capacity pen of push type according to claim 1 and 2 is characterized in that a ring-shaped step (5) fixed reset spring (6) is arranged in the penholder (4).
