A kind of pen
This utility model is related to a kind of pen.
The pen that we commonly use, needs generally plus when black by nib insertion ink bottle, then by extruding rubber storage ink sac
Mode ink be drawn into rubber storage ink sac in；Another kind of piston type pen is also required to lead to nib insertion ink bottle when adding ink
Cross twitch piston to be drawn in ink storing tube ink；So blotting when be easy to nib of making dirty, while more than time operation ability
Ink is filled, thus it is pretty troublesome when using, therefore now people commonly use disposable pen.And disposable ink pen and ink
Water is just lost after being finished, and so easily causes the wasting of resources and environmental pollution again.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model be provide a kind of simple structure, can change,
Convenient plus ink pen.
For achieving the above object, this utility model provides following technical scheme, a kind of pen, including penholder, pen core, pen
Point and cap, the penholder includes head, middle body and rear body, and the nib is plugged in head, and the pen core includes ink cartridge
With ink storage core, the nib is connected with one end of the ink cartridge, it is described in be provided with dividing plate in vivo, it is described in correspond in vivo
Dividing plate side is provided with first inner chamber, and the middle body correspondence dividing plate opposite side is provided with second inner chamber, the first inner chamber it is interior
Footpath is adapted setting with the external diameter of the ink cartridge, and the ink cartridge is plugged in the first inner chamber with respect to the nib other end,
The dividing plate correspondence second inner chamber side is provided with column-like projection block, and conducting first inner chamber and second is provided with the column-like projection block
Inner chamber leads ink passage, and the column-like projection block is plugged in the ink storage in-core, and the ink passage of leading is with the ink storage core phase
By adopting technical solutions of the utility model, when the ink runs out, easily ink storage core can be changed, and
Also easily ink storage core can be carried out plus ink.
This utility model is further arranged to：The head is provided with inner convex platform, and some numbers are provided with the inner convex platform
The elastic convex tendon of amount, the elastic convex tendon is arranged along the axis direction of head, is stayed between the elastic convex tendon and the inwall of head
There is a gap, inner side and the nib of the elastic convex tendon offset setting.
By adopting technical solutions of the utility model, when writing, nib can carry out the swing of certain amplitude, and enhancing is write
While feel, the vigour of style in writing that font can be write as the nib of brush pen is more attractive in appearance.
This utility model is further described below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is this utility model embodiment detonation configuration figure；
Fig. 2 is middle body example structure sectional view of the present utility model；
Fig. 3 is head example structure sectional view of the present utility model.
Referring to accompanying drawing 1 to accompanying drawing 3, pen disclosed in this utility model, including penholder, pen core, nib 1 and cap 2 are described
Penholder includes head 3, middle body 4 and rear body 5, and the nib 1 is plugged in head 3, and the pen core includes ink cartridge 6 and ink storage core
7, the nib 1 is connected with one end of the ink cartridge 6, and in the middle body 4 dividing plate 401 is provided with, correspondence in the middle body 4
The side of dividing plate 401 is provided with first inner chamber 402, and the correspondence of middle body 4 opposite side of dividing plate 401 is provided with second inner chamber 403, described
The internal diameter of first inner chamber 402 is adapted setting with the external diameter of the ink cartridge 6, and the relative other end of nib 1 of the ink cartridge 6 is plugged
In the first inner chamber 402, the correspondence second inner chamber 403 of the dividing plate 401 side is provided with column-like projection block 404, the column
Conducting first inner chamber 402 and second inner chamber 403 are provided with projection 404 leads ink passage 405, and the column-like projection block 404 is plugged
In the ink storage core 7, and the ink passage 405 of leading is conducted with the ink storage core 7.By using this utility model technology
Scheme, when the ink runs out, easily can change to ink storage core 7, and also easily ink storage core 7 can be carried out plus ink.
This utility model is further arranged to：The head 3 is provided with inner convex platform 301, is provided with the inner convex platform 301
A number of elastic convex tendon 302, the elastic convex tendon 302 along head 3 axis direction arrange, the elastic convex tendon 302 with
Leave gap 303 between the inwall of head 3, inner side and the nib 1 of the elastic convex tendon 302 offset setting.By adopting
Technical solutions of the utility model, when writing, nib 1 can carry out the swing of certain amplitude, while feel is write in enhancing, can
The vigour of style in writing that font is write as the nib 1 of brush pen is more attractive in appearance.
