Abstract

The utility model relates to a writing tool, in particular to a pen, which includes a pen tube and a pen point, wherein the pen tube and the pen point are connected through threads. The pen is characterized in that a cylindrical ink chamber is arranged at the rear end of the pen point; a piston is arranged in the ink chamber; the piston is connected with an external pushing handle; a transparent window is arranged on the pen tube in the position corresponding to the ink chamber; a graduation line is arranged on a side of the transparent window on the pen tube and a graduation line is arranged on the outer side of the ink chamber, so that a user can conveniently check the residual amount of ink in the ink chamber. When the pen is used, a user firstly pushes the pushing handle connected with the piston inside the ink chamber, expels air inside the ink chamber through the pen point, dips the pen point inside ink, and pulls the pushing handle of the piston. Since negative pressure is formed inside the ink chamber and ink can be smoothly injected to the ink chamber, the pen can be filled with ink at one step, and a lot of troubles are reduced for a user. The residual amount of ink can be clearly seen through the graduation lines. The writing tool has the remarkable advantages of reasonable structure, convenient use, and the like.

Description

A kind of pen

Technical field

The utility model relates to a kind of writing implement, specifically a kind of pen.

Background technology

As everyone knows, pen is one of writing implement that often uses in people's work and study, traditional pen comprises the outside shaft of a writing brush, nib and the ink cartridge that is connected with nib, in use, people need to pour into ink earlier in the ink cartridge of pen, write then, traditional ink cartridge generally uses the soft rubber capsule, when needs are irritated ink in ink cartridge, user's extruded ink water pocket makes it form negative pressure, and the nib of written front end is immersed in the ink, can pour into ink after loosing one's grip, again with nib and the shaft of a writing brush after being threaded, promptly can be used for writing, the method of tradition injection ink is very difficult disposable fills ink, simultaneously, because the shaft of a writing brush generally adopts duroplasts or metal to make, the surplus of ink cartridge ink inside can't be found out from the outside, in writing process, be easy to the situation that causes ink to use up, make troubles for people's study and work.

Summary of the invention

The utility model is at the deficiency that prior art exists, and proposes a kind of rational in infrastructure, easy to use, the pen that can understand ink remaining amount easily from the outside.

A kind of pen comprises the shaft of a writing brush, nib, and wherein the shaft of a writing brush is connected through screw thread with nib, it is characterized in that written rear end is provided with cylindrical ink cabin, ink is provided with piston in the cabin, and piston is connected with the handle that pushes away of outside, and position corresponding with the ink cabin on the shaft of a writing brush is provided with transparent window.

The utility model can transparent window one side be provided with graduation mark on the shaft of a writing brush, make things convenient for the user to understand the surplus of ink in the ink cabin.

The utility model can ink out of my cabin side be provided with graduation mark, make things convenient for the user to understand the surplus of ink in the ink cabin.

The utility model in use, the user at first promotes the handle that pushes away that is connected with ink cabin inner carrier, air in the ink cabin is discharged by nib, then nib is immersed in the ink, spur the handle that pushes away of piston, owing to form negative pressure in the ink cabin, ink can inject smoothly, thereby realize the disposable ink of filling, save trouble to the user, simultaneously, the user can be by the ink clear surplus that gets information about ink of graduation mark of side out of my cabin, in the process of writing, also can understand the residue situation of ink by transparent window on the shaft of a writing brush and graduation mark, thereby avoid causing writing situations such as interruption, the utlity model has rational in infrastructure in writing process ink inside surplus deficiency, grade easy to use is advantage significantly.

Description of drawings:

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

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is written structural representations in the utility model.

Reference numeral: the shaft of a writing brush 1, nib 2, ink cabin 3, piston 4, push away handle 5, transparent window 6, graduation mark 7.

The specific embodiment:

A kind of pen comprises the shaft of a writing brush 1, nib 2, and wherein the shaft of a writing brush 1 is connected through screw thread with written 2, it is characterized in that written 2 rear ends are provided with cylindrical ink cabin 3, be provided with piston 4 in the ink cabin 3, piston 4 is connected with the outside handle 5 that pushes away, and position corresponding with ink cabin 3 on the shaft of a writing brush 1 is provided with transparent window 6.

The utility model can transparent window 6 one sides be provided with graduation mark 7 on the shaft of a writing brush 1, make things convenient for the user to understand the surplus of ink in the ink cabin 3.

The utility model can be provided with graduation mark 7 in 3 outsides, ink cabin, makes things convenient for the user to understand the surplus of ink in the ink cabin 3.

The utility model in use, the user at first promotes to be connected with ink cabin 3 inner carriers 4 pushes away handle 5, air in the ink cabin 3 is discharged by nib, then nib is immersed in the ink, spur the handle that pushes away of piston, owing to form negative pressure in the ink cabin 3, ink can inject smoothly, thereby realize the disposable ink of filling, save trouble to the user, simultaneously, the user can be by the graduation mark 7 clear surpluses that get information about ink in 3 outsides, ink cabin, in the process of writing, also can understand the residue situation of ink by transparent window 6 on the shaft of a writing brush 1 and graduation mark 7, thereby avoid causing writing situations such as interruption, the utlity model has rational in infrastructure in writing process ink inside surplus deficiency, grade easy to use is advantage significantly.
