Abstract

The invention discloses an anti-drying mechanism for a neutral pen tip, which comprises a pen container, a pen core is arranged in the pen container, the pen tip of the pen core passes through a hole at the end of the pen container, and a sealing ring is provided at the part where the inside of the pen container is combined with the middle of the pen tip, A movably connected sealing window is arranged on the hole at the end of the pen container, and an anti-drying chamber is formed between the sealing ring and the sealing window. When using a gel pen, press the protruding button on the gel pen similar to a ballpoint pen, and the pen tip will open the sealing window from the anti-drying compartment, protrude from the end of the pen barrel, and write. After writing, press the retract button, and the pen tip will When retracting from the outside of the end of the pen holder, the sealing window is automatically closed, and the sealing window and the sealing ring form a basically sealed cavity. The extremely small space inside will not dry out the nib and will not affect future writing.

Description

Neutral nib anti-drying mechanism

technical field

The invention relates to the technical field of a gel pen writing part, in particular to a gel pen point anti-drying mechanism.

Background technique

Gel pen is the most commonly used and convenient writing tool for office work. It is cheap, fluent in writing, and easy to use. However, because the ink in the nib is water-based, it is often impossible to expose the nib to the air for a long time. , You need to cover the cap of the gel pen, otherwise the gel pen is easy to volatilize and dry due to the ink and sweat at the nib, clogging the nib, and a good gel pen will be scrapped. Because of the existence of the pen cap and its important function, once you forget to cover the pen cap, or you are in a hurry to do other things, or you can’t find the pen cap for a while, the pen will be scrapped.

Contents of the invention

The invention provides a neutral nib anti-drying mechanism which can prevent the pen core from becoming dry and scrapped without covering the pen cap.

A neutral pen tip anti-drying mechanism, comprising a pen container, a pen core is arranged in the pen container, the pen tip of the pen core passes through the hole at the end of the pen container, a sealing ring is provided at the part where the interior of the pen container combines with the middle of the pen point, and the end of the pen container A movable joint sealing window is arranged on the hole of the upper part, and an anti-drying chamber is formed between the sealing ring and the sealing window.

The sealing window is composed of two movable leaves that cooperate with each other, and the movable leaf is movably connected with the end of the pen container.

Because the present invention sets a sealing ring at the part where the inside of the pen container is combined with the middle of the nib, a movable sealing window is set on the hole at the end of the pen container, and an anti-drying chamber is formed between the sealing ring and the sealing ring. When using a gel pen, press the protruding button on the gel pen similar to a ballpoint pen, and the pen tip will open the sealing window from the anti-drying compartment, and extend out of the end of the pen holder to write. After writing, press the retract button, and the pen tip will come out of the pen holder The outside of the end is retracted, and the sealing window is automatically closed. The sealing window and the sealing ring form a basically sealed cavity. The extremely small space inside will not dry out the nib and will not affect future writing.

Description of drawings

The present invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is a structural schematic diagram of the present invention.

Detailed ways

As shown in Figure 1: a neutral pen tip anti-drying mechanism, including a pen container 1, a pen core 2 is arranged in the pen container 1, and the pen tip 3 of the pen core 2 passes through the hole at the end of the pen container 1, and the inside of the pen container 1 and the pen point 3. A sealing ring 5 is arranged at the joint part of the middle part, and a movable sealing window 4 is arranged on the hole at the end of the pen container 1, and an anti-drying chamber 6 is formed between the sealing ring 5 and the sealing window 4. The sealing window 4 is made up of two movable leaves that cooperate with each other, and the movable leaf is movably connected with the end of the pen container. Because the present invention is provided with a seal ring 5 at the position where the inside of the pen holder 1 is combined with the middle part of the nib 3, a movable sealing window 4 is set on the hole at the end of the pen holder 1, and between the seal ring 5 and the seal window 4 Form anti-dry storehouse 6, when using gel pen, press the protruding button on the gel pen similar to ballpoint pen, nib 3 backs off sealing window 4 from anti-dry storehouse 6, stretches out pen container 1 end, writes. After writing, press the retract button, the nib 3 retracts from the outside of the end of the pen holder 1, the sealing window 4 closes automatically, and the sealing window 4 and the sealing ring 5 form a basically sealed cavity, and the extremely small space inside will not Dry the nib without affecting future writing.
