Description

Ink leakage prevention pen

Technical Field

The utility model relates to a writing tools technical field, more exactly relate to an ink leakage prevention pen.

Background

A pen is a writing tool which can not be opened in study and work, and is generally composed of a pen cap, a pen holder shell, a pen point in the pen holder shell, an ink bag and other component assemblies.

In the prior art, the most part adopts the structure of adding the core on the tongue of a pen on the market, the core is fixed with glue between the pen holder, the core can not be completely sealed, ink can permeate into the space between the pen holder and the core, and the ink can slowly leak into the pen holder after the ink is absorbed under the condition, so that the ink leakage phenomenon is caused.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide an ink leakage prevention pen, this pen can effectively avoid appearing the phenomenon of ink leakage.

The technical solution of the utility model is to provide an ink leakage prevention pen with the following structure, which comprises a pen tongue, a neck core and a holding pen; the pen tongue is connected with the end part of the neck core, and the holding pen is sleeved outside the neck core; a sealing component is arranged between the top core and the pen holding body.

After the structure more than adopting, the utility model discloses an ink leakage prevention pen compares with prior art, has following advantage:

because the utility model discloses a neck core of leak protection black pen with hold and be equipped with seal assembly between the pen, receive the seal assembly effect, ink can not the seepage enter the pen-holder after the tongue has inhaled the ink, can effectively avoid appearing the phenomenon of leaking the black.

As an improvement, the sealing assembly comprises a sealing ring, the end part of the top core is provided with an annular groove, the sealing ring is matched in the annular groove, and the sealing ring seals between the top core and the pen-holding core. After adopting this kind of structure, seal assembly simple structure, the equipment is convenient, and is sealed effectual.

As an improvement, the outer surface of the neck core is provided with a limiting groove, the inner wall of the holding pen is provided with a limiting bulge matched with the limiting groove, and the limiting bulge is clamped into the limiting groove. By adopting the structure, the assembly between the neck core and the holding pen is more convenient, and the rotation between the neck core and the holding pen can be avoided.

As an improvement, one end of the limiting groove is provided with an insertion hole, the other end of the limiting groove is a closed end, and the limiting groove is arranged along the length direction of the neck core; the length of the limiting bulge is matched with that of the top core. After adopting this kind of structure, the equipment is more convenient.

As an improvement, the part of the limiting groove close to the insertion opening is in a bell mouth shape. After adopting this kind of structure, during the equipment, the horn mouth has the effect of direction to the spacing groove, makes things convenient for the neck core to insert in holding a pen.
