CN201456662U - A spiral ballpoint pen - Google Patents

Abstract

The utility model discloses a spiral ballpoint pen, which comprises a pen holder and a pen head. The pen holder is directly connected with the pen core and the pen head, and the pen holder has a densely wound spiral structure. The utility model obtained according to the above technical scheme can greatly increase the ink storage capacity of the pen core and prolong the service life of the pen core because the pen core adopts a tightly wound spiral shape; meanwhile, the pen provided by the utility model does not need a pen cap, which greatly reduces the cost.

Description

A spiral ballpoint pen

Technical field:

The utility model relates to a learning tool, in particular to a spiral ballpoint pen.

Background technique:

In the ballpoint pens currently used, the refills all adopt linear rods, and the refills must be placed in the same size pen caps. In some special cases, as in some dual-purpose pens, in order to ensure the appearance design and necessary technical indicators of the pen, the length of the rod body of the ballpoint pen core has to be shortened. This relatively reduces the ink reserve of the pen core, affects the service life of the ballpoint pen, and produces a lot of resources for the pen cover.

Utility model content:

In order to solve the problems existing in the existing ball-point pens, the utility model provides a spiral ball-point pen capable of enlarging the ink of the pen core.

In order to achieve the above object, the utility model adopts the following technical solutions:

A spiral ballpoint pen comprises a pen holder and a nib, the pen holder is directly connected to the pen core and the nib, and the pen holder has a densely wound spiral structure.

Grooves and projections for easy handling are provided on the outer surface of the tightly wound and spiral-shaped penholder.

The utility model obtained according to the above technical scheme can greatly increase the ink storage capacity of the pen core and prolong the service life of the pen core because the pen core adopts a tightly wound spiral shape; meanwhile, the pen provided by the utility model does not need a pen cap, which greatly reduces the cost.

Description of drawings:

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

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

Detailed ways:

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

In order to solve the existing problems of the existing ball-point pen, the utility model adopts a spiral type ball-point pen which can increase the pen core ink as shown in Figure 1 .

As shown in the figure, this spiral type ballpoint pen includes a pen holder 1 and a nib 2, wherein the pen holder is a pen core and its interior is hollow with ink, and is directly connected with the nib.

In order to increase the amount of ink stored in the pen core, the utility model designs the penholder 1 (also the pen core) as a tightly wound spiral structure.

Simultaneously in order to feel good when holding a pen and writing, the utility model is evenly provided with grooves 3 and projections 4 on the outer surface of the pen holder 1 that is tightly wound around the spiral shape.

The penholder 1 (or pen core) of the present utility model adopts transparent material support, how much the ink reserve in the ballpoint pen has like this will be clear at a glance.

The utility model obtained according to the above technical scheme can greatly increase the ink storage capacity of the pen core and prolong the service life of the pen core because the pen core adopts a tightly wound spiral shape; meanwhile, the pen provided by the utility model does not need a pen cap, which greatly reduces the cost.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.

Claims (2)

1. a screw type ball pen comprises penholder and nib, it is characterized in that, described penholder is that pen core directly is connected with nib, and penholder is close around helical structure.

2. a kind of screw type ball pen according to claim 1 is characterized in that the outer surface of described penholder is provided with groove and the projection of being convenient to hold.
