[0030] The following describes the specific embodiments of the present utility model with reference to the drawings.
[0031] Embodiment
[0032] As Figures 1-5As shown in the figure, a preferred embodiment of the pen cap provided by the present invention includes a main body 1. The main body 1 has a columnar cap cavity 11 and an orifice 12 communicating with the cap cavity 11, and further includes at least two groups of rib groups 2. Each group of rib groups 2 has a number of pen-clamping ribs 20, and the pen-clamping ribs 20 are distributed along the length direction of the cap cavity 11. The distances of the pen-clamping ribs 20 in different groups from the length central axis of the main body 1 are different, and a number of pen-clamping ribs 20 in the same group are distributed along the circumferential direction of the cap cavity 11, thereby forming a bayonet suitable for pen rods of different thicknesses. In this embodiment, the shape of the main body 1 is an irregular columnar structure. Correspondingly, the cap cavity 11 is also an irregular column. Therefore, for the distance of the pen-clamping ribs 20 from the length central axis of the main body 1, in this solution, it should be understood as the average value of the distances from each point on the pen-clamping ribs 20 to the length central axis of the main body 1. Each group of pen-clamping ribs 20 has three, and they are evenly distributed in the cap cavity 11.
[0033] For the convenience of understanding this case, the naming rule of each rib group 2 is that starting from the orifice 12, they are named the first rib group 21 to the Nth rib group 2 in sequence.
[0034] Specifically, the distribution positions of each group of rib groups 2 in the cap cavity 11 are not completely the same. For example, each group of rib groups 2 is arranged in sequence along the length direction of the cap cavity 11. Or, for example, in this embodiment, there are two groups of rib groups 2. The first rib group 21 extends from the orifice 12 to the end far from the orifice 12, and the second rib group 22 starts from the middle of the cap cavity 11 and extends to the end far from the orifice 12. Therefore, there is a certain overlap between the first rib group 21 and the second rib group 22 in a section far from the orifice 12.
[0035] The lengths of the projections of each group of rib groups 2 onto the length central axis of the cap cavity 11 are the same, that is, they are arranged in sequence along the length direction of the cap cavity 11; or the length ratio of the projection of the first rib group 21 to the Nth rib group 2 onto the length central axis of the cap cavity 11 is: 1:1 / (2^N). In this embodiment, the projection length ratio of the first rib group 21 and the second rib group 22 is 1:2.
[0036] Compared with the pen-clamping ribs 20 close to the orifice 12, the pen-clamping ribs 20 far from the orifice 12 are closer to the main body 1 along the length central axis, that is, the distance of the rib group 2 from the main body 1 along the length central axis is inversely proportional to the distance of the rib group 2 from the orifice 12. One of the purposes is to clamp a pen with a thicker pen diameter at the bayonet at one end close to the orifice 12. The deeper into the cap cavity 11, the thinner the pen diameter suitable for the bayonet, thus forming a more reasonable structural layout. In some other embodiments with poor effects, by setting ribs made of flexible materials, the rib groups 2 can be arranged without following the above rules. For example, the rib group 2 far from the orifice 12 is set to be farther from the central axis of the cap cavity 11, and the rib group 2 close to the orifice 12 is set to be closer to the central axis of the cap cavity 11.
[0037] Furthermore, the pen clamping rib 20 is made of a flexible material. Under the action of an external force, the pen clamping rib 20 can deflect to a certain extent in the circumferential direction of the cap cavity 11. By providing the flexible pen clamping rib 20, the pen barrel can be clamped more tightly. At the same time, the range of applicable pen barrels is further expanded.
[0038] Furthermore, a through hole 13 is provided at one end of the main body 1 away from the cavity opening 12; the through hole 13 communicates with the cap cavity 11, thereby preventing the end of the cap cavity 11 from forming air pressure due to the extrusion of the pen tip, resulting in poor pen clamping effect.
[0039] Furthermore, it further includes at least one counterweight 3, which is connected to the main body 1 and is located at one end of the cavity opening 12 or at one end away from the cavity opening 12. One of the purposes is to enable the pen cap to stand on the desktop for placement, to a certain extent avoiding it rolling off the desktop and being lost. Several counterweights 3 can be provided and distributed along the circumferential direction of the main body 1. In this embodiment, four counterweights 3 are provided, arranged circumferentially on the main body 1 and located on the outer wall at one end close to the cavity opening 12.
[0040] One end of the main body 1 away from the cavity opening 12 is conical or bullet-shaped, so that the rib group 2 at the end away from the cavity opening 12 has the position advantage of being closer to the central axis of the cap cavity 11, thereby saving material costs and conforming to the environmental protection policy of sustainable development.
[0041] Preferably, each group of pen clamping ribs 20 is evenly distributed or symmetrically distributed in the cap cavity 11.
[0042] Furthermore, the main body 1 is at least made of a transparent material or provided with an observation window on the side away from the cavity opening 12, so as to facilitate the observation of the pen tip state to judge whether the pen needs to be sharpened or whether to select this pen. In this embodiment, the pen cap main body 1 can be divided into two parts, a first section and a second section, along the length direction. The first section is a tubular structure with the cavity opening 12, and the second section is bullet-shaped and made of a transparent material.
[0043] A pen cap of the present utility model forms clamping openings suitable for pen barrels of different thicknesses by providing multiple groups of rib groups in the cap cavity of the pen cap, so as to be applicable to pen holders with pen barrels of different thicknesses, achieving the purpose of protecting the pen tip and avoiding polluting other stationery items.
[0044] The above embodiments only represent a part of the implementation manners of the present invention. Without departing from the concept of the present invention, several deformations, substitutions, and improvements made by those skilled in the art without creative labor all fall within the protection scope of the present invention.
