Abstract
It the utility model is related to a kind of pen cap, solve and connected between the existing cap for brush and pen body using the buckle structure of evagination, buckle is caused easily to be shaken when separating, so that ink the defects of oozes out at nib and remained to the cap for brush, including overcoat, the volute spring being arranged in overcoat, the bigger diameter end of volute spring is towards the openend of overcoat, and the miner diameter end of volute spring is towards the inner of overcoat.Jacket internal is provided with volute spring, volute spring can with axial tension, while also can radial deformation, during the insertion of such pen pen body, volute spring wales pen pen body, when extracting the cap for brush, volute spring deforms therewith, with the length increase of extraction, volute spring separates with pen body, it is not in vibrations that pen body, which is inserted in extraction, avoids ink from being oozed out from nib, it is ensured that clean and tidy inside the cap for brush.
Description
Technical field
A kind of cap for brush is the utility model is related to, especially a kind of pen cap.
Background technology
Pen has had very long history as writing implement, but how to change, and pen still can not depart from ink
Water is individually write.
Ink is the necessary materials of pen writing, and ink belongs to mobility, although do not write, ink is not from nib
Outflow, but can also be flowed in pen, ink is also to maintain activity.
When the cap for brush is nested with pen body, in order to ensure that the cap for brush does not drop from pen body, it can be set between the cap for brush and pen body
There is disconnecting prevention structure, the disconnecting prevention structure of the existing cap for brush is using raised buckle structure, buckle structure, although being avoided that the cap for brush mostly
Drop, but when the cap for brush is extracted, when separating snapped-in position, easily shake, at this moment ink can ooze out from nib,
Ink is left inside the cap for brush, when so nib is inserted next time, ink can be stained with outside pen body, make finger section dirty.
The content of the invention
The utility model is solved and connected between the existing cap for brush and pen body using the buckle structure of evagination, causes buckle point
From when easily shake so that ink the defects of oozes out at nib and remained to the cap for brush, there is provided a kind of pen cap, adopts
Pen body is held tightly with a kind of elastic hoop structure, avoids shaking when extracting the cap for brush, ink will not ooze out from nib.
Technical scheme is used by the utility model solves its technical problem：A kind of pen cap, including overcoat, setting
In the volute spring in overcoat, the bigger diameter end of volute spring is towards the openend of overcoat, and the miner diameter end of volute spring is towards overcoat
The inner.Jacket internal is provided with volute spring, volute spring can with axial tension, while also can radial deformation, such pen
When pen body is inserted, volute spring wales pen pen body, and when extracting the cap for brush, volute spring deforms therewith, increases with the length of extraction
Add, volute spring separates with pen body, and it is not in vibrations that pen body, which is inserted in extraction, avoids ink from being oozed out from nib, it is ensured that pen
It is clean and tidy inside cap.
Preferably, jacket internal is provided with cylindrical hole, the bigger diameter end of volute spring is connected with cylindrical hole inwall
It is fixed.There is gap, the gap is easy to volute spring to deform between cylindrical hole inwall and volute spring outside.
Preferably, the openend of overcoat is provided with rib, bigger diameter end and the rib of volute spring abut against.Rib can be kept away
When exempting to extract pen body, volute spring drops out out of the cap for brush.
Preferably, volute spring is volute spring made of plastic, the long length less than overcoat of original of volute spring.
Preferably, one end of overcoat is connected with extension cap, this one end of cap closure overcoat is hung.
It is threadedly coupled preferably, hanging and being used between cap and overcoat end.Hanging cap can be separated with overcoat, reveal after separation
Go out inside the cap for brush, it is convenient for assembly.
Preferably, hanging cap is internally provided with rubber anti-collision block, the middle part of rubber anti-collision block is provided with the cone of indent
Shape hole, bellmouth is towards jacket internal.When being avoided that nib insertion rigid collision occurs for rubber anti-collision block, it is ensured that nib safety.
The beneficial effects of the utility model are：Jacket internal is provided with volute spring, and volute spring can be with axial tension, together
When also can radial deformation, during the insertion of such pen pen body, volute spring wales pen pen body, when extracting the cap for brush, volute spring with
Deformation, with the length increase of extraction, volute spring separates with pen body, and it is not in shake that pen body, which is inserted in extraction, is kept away
Exempt from ink to ooze out from nib, it is ensured that clean and tidy inside the cap for brush.
