Description
Technical field
This utility model is related to field of stationery, more particularly to a kind of new space pen core.
Background technology
Conventional sign pen core end scribbles sealing fluid, however, this is designed with two defects, first is sealing fluid
It is not enough to the sealing of ink, it is susceptible to leakage, second is that ink relies on as a rule gravity and down supplies, once pen core
Nib is placed upwards by long-time, and ink can be difficult to supply at the ball of nib again, affect to write.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide new space pen core, depositing
The chamber of oil storage ink keeps certain pressure, facilitates ink supply, it is to avoid ink affects to write toward a tail direction rollback, and strengthen it is right
The sealing of ink, further reduces leakage.
For achieving the above object, this utility model is adopted the following technical scheme that：
New space pen core, including a pen core body, the pen core body has one to be used to store the storage pipe portion of ink
And one be used for the written portion write, one end of the storage pipe portion is embedded with a tail plug, the tail plug with store the interior of pipe portion
A hot melt adhesive film is coated between wall；The other end connection nib portion of the storage pipe portion, stores interior with an activity in pipe portion
Storage tube portion is divided into plug, the interior plug first chamber and the second chamber near tail plug near nib portion, and this second
Within the chamber has spring, and the spring one end is connected to interior plug, and the tail is provided with beyond the Great Wall a mounting seat, the other end of the spring
It is installed on mounting seat；Circumferentially extending cannelure is offered on the perisporium of the interior plug, the first lubrication is filled with the cannelure
Lipid layer, the second grease layer is coated with the second chamber on one end of interior plug；The first chamber near interior plug one
End is filled with nitrogen sealing coat, and the nitrogen sealing coat is used to isolate in ink and Nei Sai.
Preferably, transition part and conveying pipe portion are included between the other end of the storage pipe portion and nib portion successively, it is described defeated
Send the diameter of pipe portion less than the diameter of storage pipe portion, the transition part is used for connection storage pipe portion and conveying pipe portion, transition part
Diameter is from storage pipe portion to conveying pipe portion gradual change.
Preferably, actively it is embedded with a tungsten carbide ball in the written portion.
Preferably, guide post is provided with the mounting seat, the spring is socketed on guide post, and the spring provides one and makes
The elastic stress that get Nei Sai is moved to the direction away from mounting seat；When the new space pen core is write, positioned at first chamber
Interior ink is gradually decreased, and the liquid level of ink is shifted toward nib portion, and spring gradually extends, and the elastic stress is consistently equal to the ink
Viscous force.
Compared to prior art, there is this utility model the interior plug of activity, painting to be located at the first grease of interior plug cannelure
Layer and painting are located in second chamber the second grease layer near one end of interior plug, and internally fill in offer elasticity using spring
Stress, the ink that will be stored in first chamber keeps certain pressure.During constantly writing, due to ink level constantly to
Written portion keeps the pressure of ink to be conducive to the continuous ink feeding to written portion during shifting；The design can also avoid ink
Because, toward a tail direction rollback, this utility model strengthens the sealing to ink the reason for gravity, leakage is further reduced.

Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, this utility model is described further：
As shown in Figure 1 and Figure 2,
New space pen core, including a pen core body, the pen core body has one to be used to store the storage pipe portion 1 of ink
And one be used for the written portion 2 write, one end of the storage pipe portion is embedded with a tail plug 10, the tail plug 10 and storage pipe portion
A hot melt adhesive film 14 is coated between 1 inwall, the hot melt adhesive film 14 is used to fix tail plug 10；The storage pipe portion 1 it is another
End connection nib portion 2, stores the interior plug 6 with an activity in pipe portion 1, and the interior plug 6 is separated into storage pipe portion 1 near nib
The first chamber 5 in portion 2 and the second chamber 12 near tail plug 10, have spring 11, the spring 11 in the second chamber 12
One end is connected to interior plug 6, and a mounting seat 8 is provided with the tail plug 10, and the other end of the spring 11 is installed on mounting seat 8, institute
Circumferentially extending cannelure 7 is offered on the perisporium for stating interior plug 6, the first grease layer is filled with the cannelure 7, described second
The second grease layer is coated with chamber 12 on one end of interior plug 6.The first chamber is filled with nitrogen near one end of interior plug
Air bound absciss layer 13, the nitrogen sealing coat 13 is used to isolate in ink and Nei Sai 6.The nitrogen sealing coat 13 may also operate as avoiding oil
Ink is contacted with the first grease layer, reduces the rotten chance of ink.
As a kind of preferred scheme, between the other end of the storage pipe portion 1 and nib portion 2 successively include transition part 4 and
Conveying pipe portion 3, less than the diameter for storing pipe portion 1, the transition part 4 is used for connection storage pipe portion 1 to the diameter of the conveying pipe portion 3
