CN203496492U - Simple splitting device for nib and refill tube of refill - Google Patents

Abstract

The utility model discloses a splitting device for a nib and a refill tube of a refill. The device comprises a substrate, wherein a refill through hole for the nib to be placed downwards and into which the refill is inserted is formed in the substrate, and the edge of the lower end face of the refill through hole is provided with a stopping part; the stopping part is matched with a flange on the nib in a stopping way to block the nib to move upwards. The simple splitting device provided by the utility model has the advantages of simple structure, lower cost, full saving in useful resources, economy and environmental protection, and the nib and the refill tube of the refill can be split, so that an empty refill can be repeatedly used by injecting writing liquid.

Description

The simple and easy detachment device of written core pipe of pen core

Technical field

The utility model relates to a kind of simple and easy detachment device of written core pipe of ball pen.

Background technology

Ball pen is very important a kind of writing appliance in the middle of people's daily life, working and learning, it is to be mainly comprised of penholder and the pen core being arranged in penholder, wherein, pen core is by nib, core pipe and be filled in an oil in core pipe or the writing liquid such as ink forms, in nib, there is the flange coordinating with core pipe lower end block, and the side face of the outstanding core pipe of the outline of this flange.This pen core in use; after being finished, conventionally empty pen core can be lost as rubbish writing liquid in pen core; if in fact this empty pen core can reinject, writing liquid just can be reused, and is to be dropped at present, and this has just caused the waste of useful resources.

Summary of the invention

The purpose of this utility model is to provide a kind of nib of pen core and core pipe can being split so that the writing liquid of annotating makes the sky pen core can the simple and easy detachment device of reusable written core pipe.

For achieving the above object, the utility model adopts following technical scheme:

The simple and easy detachment device of written core pipe of a kind of pen core of the utility model, this device comprises substrate, on substrate, having can be for the interspersed pen core perforation of the catotropic pen core of pen, and the lower end face of pen core perforation has for the flange block with in nib and coordinates to stop the stop section of moving in nib along place.

Described pen core perforation is circular hole, and the diameter of this circular hole is greater than the external diameter of pen core core pipe, is less than the external diameter of described flange.

Described substrate is dull and stereotyped.

Described substrate is circular, and its periphery bends downwards.

Compared with prior art the beneficial effects of the utility model are: owing to adopting technique scheme, the utility model in use, empty pen core is penetrated to pen core perforation, nib, with the direct depoling pipe upwards of hand, thereby is separated nib and core pipe by block under pen core perforation, can again in core pipe, inject writing liquid, then the assembling again by core pipe, nib can make sky pen core be reused, and fully saves useful resources, economic environmental protection.Certainly, nib has been damaged and can more have been renewed nib.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the top view of substrate in Fig. 1.

The specific embodiment

The simple and easy detachment device of written core pipe of the pen core shown in Fig. 1-2, it comprises substrate 11, on substrate 11, having can be for the interspersed pen core perforation of the catotropic pen core 1 of pen, and the lower end face of pen core perforation has for the flange block with in nib and coordinates to stop the stop section of moving in nib along place.As preferably, described pen core perforation is circular hole 13, and the diameter of this circular hole is greater than the external diameter of pen core 1 core pipe, is less than the external diameter of described flange.Described substrate 11 is one flat plate, and this flat board can be metal material, can be also rigid plastics.Dull and stereotyped shape can be any shape, for example casper.As preferably.Described substrate 11 is circular, and its periphery bends downwards, and kink forms bearing.
