Description
Technical Field
[0001] The utility model relates to the technical field of pens, in particular to a pen that guides correct gripping posture. Background Art
[0002] At present, most of the pen barrels on the market are mainly round. The reason why round pen barrels are popular is that they provide the following advantages: Universal applicability: The cylindrical design is suitable for the natural grip of most people's hands, and will not restrict users due to specific angles or directions, which increases the comfort of use. Material saving and production convenience: The round design is simpler in the manufacturing process, saves materials, and is easy to mass produce. In addition, there are a small number of pen barrels with square shapes. The shape of this pen barrel is also simpler to manufacture, but the non-circular edges may cause discomfort to the palm or fingers when holding for a long time, especially the angular design may cause pressure points.
[0003] However, whether it is a square pen holder or a round pen holder, it is not well suited to the contour of the hand when a person holds a pen correctly, and therefore is not suitable for assisting users to master the correct pen holding posture.
[0004] With the development of technology, some pens have appeared with special-shaped pen barrel sections. Although they can adapt to the contour of a person's hand when holding the pen to a certain extent, the surface of the pen barrel is still flat, and the transition angles between the planes are very sharp. The disadvantage is that when designing the inner diameter of the pen barrel, considering that most pen refills are round, the size of the pen barrel with a flat surface must be designed to be slightly larger so that its inner diameter can be large enough to accommodate the round pen refill. However, this will make the size of the pen barrel too large, affecting the comfort of holding the pen. In addition, the transition angle of this type of pen barrel is very sharp, which will also form a pressure point, which will also affect the comfort of holding the pen.
[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION
[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0024] According to an embodiment of the utility model, a correct grip guide pen is provided, combined with Figure 1-4 , including a pen holder 1 and a refill 2 arranged in the pen holder 1, the outer surface of the pen holder 1 is constructed as a trapezoidal surface, and the trapezoidal surface is enclosed by a first surface 3, a second surface 4, a third surface 5, and a fourth surface 6 connected in sequence, and the first surface 3, the second surface 4, the third surface 5, and the fourth surface 6 are all arcuate edges, wherein two adjacent arcuate surfaces are transitionally connected by an arc angle 7. The cross-section of the pen holder 1 designed in this way has an inner circumference that is closer to the outer circumference of the circular refill 2 as a whole. When designing the size, the diameter of the inner cavity must be excessively enlarged relative to the straight surface pen holder 1, which is conducive to reducing the size of the pen holder 1 and improving the comfort of holding the pen. In particular, the arc angle 7 serves as a transition, which can further reduce the pressure point when holding the pen.
[0025] In this embodiment, the first surface 3 and the third surface 5 are arranged substantially in parallel, the second surface 4 is arranged substantially perpendicular to the first surface 3 and the third surface 5, respectively, and the fourth surface 6 is arranged obliquely relative to the first surface 3 and the third surface 5 to enclose a right-angle trapezoidal cross section. Such a structure is more in line with the shape of the inner side of a human hand when holding a pen, which is conducive to assisting in correcting the pen-holding posture.
[0026] For the four-sided correct grip guide pen of the present embodiment, since the cross-section is generally an asymmetric tetrahedron rather than a circle, if the pen head is connected to the pen shaft with threads, the size must be increased in order to construct an inscribed circle in the tetrahedron pen shell to form threads and to form an aperture inside to meet the inner hole through which the pen core 2 passes. However, this will increase the material usage and processing difficulty, and when the outline size increases to a size greater than the comfortable spacing between the thumb, index finger, and middle finger when holding the pen, the comfort of holding the pen will be reduced.
[0027] To solve the above problems, in this embodiment, the tail end of the pen body 1 is further provided with an inner cylinder 8, the tail end of the pen body 1 is internally configured with an inner connecting portion 9, and the inner side of the inner connecting portion 9 is configured with an inner thread 15; the outer circumference of the first end of the inner cylinder 8 is configured with an outer thread 10 adapted to the inner thread 15, and the end face of the first end is provided with a spring 11, and the inner cylinder 8 is screwed into the inner connecting portion 9 by means of the outer thread 10 and the inner thread 15, so that the spring presses against the tail end of the pen core 2; a groove body is provided on the second end of the inner cylinder 8, and a rear end cover 12 is further provided at the tail end of the pen body 1, and the edge of the rear end cover 12 is adapted to the groove body. In this embodiment, the groove body is a straight groove body 13. The inner cylinder is also configured with anti-slip grooves 14 on the outer circumference away from the pen core 2.
[0028] In this embodiment, the refill 2 is installed at the rear end, and the rear end structure of the pen body 1 can pass through the internal threaded hole of the refill 2 (that is, the internal thread 15 on the inner side of the internal connecting part 9). An inner cylinder with an anti-skid pattern 14 with a straight groove 13 at the rear end is installed and blocks the internal threaded hole through threads, and a spring 11 is used to provide thrust for the refill 2. The edge of the rear end cover 12 can be embedded in the straight groove 13 at the rear end of the inner cylinder 8 to play the role of a screwdriver to rotate the inner cylinder 8. It plays a role when the inner cylinder 8 protrudes from the end of the pen body 1 and is not easy to be pinched by hand. The inner cylinder 8 protrudes a long distance, and the anti-skid pattern 14 can be pinched by hand to rotate the inner cylinder 8 to prevent slipping.
[0029] In this embodiment, the anti-slip patterns 14 are convex ridges that are spaced apart along the circumference of the inner cylinder 8 and are parallel to the axis of the inner cylinder 8 .
[0030] In this embodiment, the rear end cover 12 includes an outer cover body 121 and an inner cover body 122. After the outer cover body 121 is buckled onto the rear end of the pen shaft 1, the lower edge of the outer cover body 121 is spliced with the upper edge of the rear end of the pen shaft 1, and the inner cover body 122 extends into the interior of the rear end of the pen shaft 1. The outer surface of the inner cover body 122 can fit the inner surface of the pen shaft 1 to increase friction and improve the tightness of the buckling of the rear end cover 12.
[0031] In this embodiment, the lower end surface of the inner cover body 122 is provided with protrusions 123 arranged at intervals to better embed into the I-shaped groove body 13.
[0032] When in use, the plane for holding the pen by the thumb is the second surface 4, the plane for holding the pen by the index finger is the third surface 5, and the plane for holding the pen by the middle finger is the fourth surface 6. Among them, the first surface 1 is the smallest and is the side plane without force. When writing, the middle finger presses against the fourth surface 6 of the pen shaft. When writing vertically, the index finger presses the third surface 5 downward. When writing horizontally, the thumb pushes the second surface 4 to the right.
[0033] It should be understood that the core protection focus of the utility model is that any part of the pen that has a trapezoidal shape as described in the above embodiment will be considered an infringement. Any equivalent changes made on this basis will fall within the protection scope of the utility model.
[0034] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
