Abstract

The utility model provides a writing pen, which comprises a refill, a tip sleeve, a middle section, a soft sheath, a pen holder and the like. The outer periphery of the cross section of the pen holding part of the middle section of the pen is triangular, the outer periphery of the cross section of other parts of the middle section of the pen is circular, and meanwhile, the soft sheath arranged outside the middle section is cylindrical to form an inner triangular structure of the pen holding part. The outer surface of the middle section covered by the soft sheath is provided with raised anti-skid grains; the inner surface of the soft sheath is provided with concave anti-slip lines. When the pen is not used, the middle section of the pen is cylindrical, so that the pen accords with public aesthetic, when the pen is used, the soft sheath of the pen sinks to form a triangular shape, the contact part of the fingers and the middle section is a plane, so that the fatigue of hand muscles is greatly relieved, the pen is more stable and antiskid to be held, the pen more accords with human engineering, and meanwhile, a writer can be enabled to form a correct pen holding posture.

Description

Writing pen

The technical field is as follows:

the utility model relates to a writing tool field especially relates to a hold pen and feel better pen.

Background art:

at present, the known pen holding positions of fingers such as gel pens, ball-point pens, pencils and propelling pencils are mostly cylindrical, and the contact positions of the fingers and the pens are small, so that the fingers are easy to fatigue when the pen is used for writing for a long time.

Although the existing part of pens is additionally provided with a soft sheath at the pen holding position, or the pen holder is directly made into a triangular shape. The soft sheath can slightly relieve the writing fatigue, but the essence is the same, and the contact part area of the finger and the pen is not increased; although the triangular pen with the pen holder greatly increases the contact part area between fingers and the pen, the pen is stable to hold and better in hand feeling, and is not in accordance with the aesthetic sense of the public.

The invention content is as follows:

the utility model aims at providing a both remain the columniform appearance that the pen-holder more accords with masses aesthetic, simultaneously, the pen of holding that has the pen-holder triangle-shaped form again is stable, comfortable, still possesses more feels better advantage than the current pen of taking the soft sheath, greatly alleviates the tired pen of writing of hand muscle.

The main technical content of the utility model is as follows:

a writing pen, characterized in that: the pen finger is used for writing, the peripheral shape of the cross section between the middle sections (4) C and D is triangular, the peripheral shape of the cross section between the other parts, namely the cross section between the middle sections (4) E and C and the cross section between D and F is circular, and meanwhile, the soft sheath (3) arranged outside the middle sections (4) is cylindrical to form an inner triangular structure between the pen holding parts C and D; convex anti-skid lines are arranged on the outer surface between the middle sections (4) E and F; the inner surface of the soft sheath (3) is provided with concave anti-slip lines.

The utility model has the advantages that: by adopting the scheme, when the pen is in a non-use state, the middle section part of the pen is cylindrical, so that the pen accords with public aesthetics, when the pen is used, the soft sheath at the pen holding part of the finger is sunken into a triangle, the contact part of the finger and the middle section is a plane, so that the fatigue of hand muscles is greatly relieved, the pen holding is more stable and more anti-skidding, the pen holding more accords with ergonomics, and meanwhile, a writer can be enabled to form a correct pen holding posture.

Description of the drawings:

the present invention will be further explained with reference to the drawings and examples.

In the drawing, (1) is a pen core, (2) is a tip sleeve, (3) is a soft sheath, (4) is a middle section, and (5) is a pen holder.

fig. 8 is a schematic cross-sectional view of a writing pen along the central axis of the middle section when the soft sheath is tightly attached to the middle section when the pen is held by fingers in use.

Fig. 9 is a schematic cross-sectional view of a writing pen according to an embodiment of the present invention, the cross-sectional view being taken along point a in fig. 8.

The specific implementation mode is as follows:

example (b): as shown in fig. 1 and 2, the writing pen of the embodiment includes a pen core (1), a tip sleeve (2), a soft sheath (3), a middle section (4) and a pen rod (5); the pointed sleeve (2) is conical and is in threaded connection with the middle section (4), the middle section (4) is in threaded connection with the pen rod (5), the pen rod (5) is in a cylindrical shape with the outer diameter of about 1 cm, and the outer diameters of other accessories and the size ratio of the pen rod (5) are as shown in figure 1; the soft sheath (3) is arranged at the periphery of the middle section (4), and the pen core (1) is arranged in the tip sleeve (2), the middle section (4) and the pen holder (5). As shown in fig. 3, 5 and 7, the cross section of the middle section (4) from the part E to the part C and the cross section of the part D to the part F are circular, so that the soft sheath (3) is cylindrical in a non-use state; as shown in figures 4 and 6, the periphery of the cross section between the pen holding parts C and D of the middle section (4) is triangular, so when a user holds a pen with fingers, the soft sheath (3) is tightly attached to the middle section (4), the cross section of the soft sheath (3) is changed into the triangular shape, as shown in figures 8 and 9, the contact part of the fingers and the soft sheath (3) is a plane, the fatigue of hand muscles is greatly relieved, the pen holding is more stable, the pen holding device is more in accordance with ergonomics, and meanwhile, a writer can be enabled to have a correct pen holding posture. As shown in FIG. 2, the length from the point G at the top end of the writing point of the writing pen to the point C at the pen holding position of the middle joint (4) is 22 mm, and the length from the point C at the pen holding position of the middle joint (4) to the point D is 19 mm. The outer surface of the middle section (4) is provided with convex anti-slip lines, and the inner surface of the soft sheath (3) is provided with concave anti-slip lines, so that hands are not easy to slip during writing.
