CN207842438U - A kind of pen core - Google Patents

Abstract

The utility model is related to a kind of pen cores, belong to a kind of writing implement, it is characterised in that the pen core is made of nib, connector, pen core oil pipe, and with connector using being fixedly connected, pen core oil pipe is docked with the connection of connector using screw thread nib.The utility model can write when nib damage and ink be not used in the case of replace it is intact nib and connector, can be continuing with later, solve the problems, such as that writing pen nib is not easy to replace in the market instantly.The utility model is simple and reasonable, and facilitates manual operations, meets very much the demand that people use pen core.

Description

A kind of pen core

Technical field

The utility model is related to a kind of writing implement, specifically a kind of detachable assembling pen core.

Background technology

Common pen core is mostly fixedly connected and is constituted by nib, connector, pen core oil pipe currently on the market, not easy to remove, It can not be continuing with after nib damage occurs in writing process because intact nib can not be replaced, thus cause largely to provide Source wastes and environmental pollution.

Invention content

In order to solve the problems, such as that existing pen core can not replace nib, the utility model provides a kind of pen core, the writing pen Intact nib can be replaced when nib is damaged.

Scheme is used by the utility model solves its technical problem：Pen core is divided into nib, connector, pen core oil Pipe, it is characterised in that with connector using being fixedly connected, connector is docked with pen core oil pipe using screw thread nib.If nib damage It is bad, then the connector and pen core oil pipe using screw thread docking can dismantle separation, replace again later one group of intact nib with Connector can be used continuously.

In order to prevent ink from overflowing in normal use, connector is equipped with rubber pad, the rubber with the place of docking of pen core oil pipe Rubber cushion can reduce the gap docked between connector and pen core oil pipe, prevent ink from overflowing to reach.

The utility model is simple in structure, the nib of replaceable damage, and very convenient manual operations, is more in line with people couple The demand that pen core uses.

Specific implementation mode

Embodiment 1, written (3) are fixedly connected with connector (2), disposed thread (5) docking of connector (2) inner upper end The external thread (3) of the external lower end of pen core oil pipe (1).When written (3) are damaged, first by connector (2) and pen core oil pipe (1) point It leaves, then replaces one group of intact nib (3) and connector (2) again, set at connector (2) and pen core oil pipe (1) docking There is rubber pad (6), ink overflows when preventing from using.

Claims (3)

1. a kind of pen core is made of written (3), connector (2), pen core oil pipe (1), it is characterised in that：Written (3) and connector (2) using being fixedly connected, pen core oil pipe (1) is docked with connector (2) using screw thread.

2. pen core according to claim 1, it is characterised in that described connector (2) inner upper end has disposed thread (5) With rubber pad (6).

3. pen core according to claim 1, it is characterised in that there is external thread in the external lower end of the pen core oil pipe (1) (4)。
