CN201456662U - Spiral ball pen - Google Patents

Abstract

The utility model discloses a spiral ball pen, which comprises a pen holder and a pen point, wherein the pen holder is formed by directly connecting a pen core and the pen point, and the pen holder is in a tightly wound spiral structure. According to the technical scheme, because the pen core is in the tightly wound spiral structure, the ink storage volume of the pen core can be greatly increased, the service life of the pen core is prolonged, and a pen cap is eliminated so at the same time so as to greatly reduce the cost.

Description

A kind of screw type ball pen

Technical field:

The utility model relates to a kind of learning tool, particularly a kind of spiral helicine ball pen.

Background technology:

The present ball pen that uses, pen core all are to adopt the linear pattern body of rod, and pen core must be enclosed within the measure-alike pen cap.At some in particular cases, as in some double-purpose pens,, have to shorten the body of rod length of refill for ball-point pen in order to guarantee the appearance design and the necessary technology index of pen.So just reduced the printing ink reserves of pen core relatively, influenced the useful life of ball pen, produced the pen cap and also wasted many resources.

The utility model content:

The utility model has the existing problem of ball pen now in order to solve, and a kind of screw type ball pen that can increase pen core printing ink is provided.

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

A kind of screw type ball pen comprises penholder and nib, and described penholder is that pen core directly is connected with nib, and penholder is close around helical structure.

Described close outer surface around spiral helicine penholder is provided with groove and the projection of being convenient to hold.

The utility model that obtains according to technique scheme can increase the printing ink reserves of pen core, the useful life that prolongs pen core greatly because pen core adopts closely around spirality; The pen that the while utility model provides has saved the pen cap, greatly reduces cost.

Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

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

The specific embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

The utility model has the existing problem of ball pen now in order to solve, and has adopted a kind of screw type ball pen that can increase pen core printing ink as shown in Figure 1.

As shown in the figure, this screw type ball pen comprises penholder 1 and nib 2, and wherein penholder is that its inner hollow of pen core is equipped with printing ink, and directly is connected with nib.

In order to increase pen core storage quantity of ink, the utility model is designed to penholder 1 (also being pen core) close around helical structure.

Good hand touch when writing in order can formula to hold a pen simultaneously, the utility model is at close groove 3 and the projection 4 of being provided with uniformly on the outer surface of spiral helicine penholder 1.

Penholder 1 of the present utility model (or pen core) adopts transparent material to support, and how many printing ink reserves in the ball pen have to come into plain view like this.

The utility model that obtains according to technique scheme can increase the printing ink reserves of pen core, the useful life that prolongs pen core greatly because pen core adopts closely around spirality; The pen that the while utility model provides has saved the pen cap, greatly reduces cost.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

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.
