Abstract
Description
Technical Field
[0001] This utility model relates to the field of stationery technology, and in particular to a shock-absorbing pen cover. Background Technology
[0002] As an indispensable writing tool in daily life and work, the design of pens directly impacts user experience and health. With the increasing demands for writing and drawing in modern society, fatigue, hand muscle soreness, and even joint damage caused by prolonged pen use are becoming increasingly prominent. Especially for high-frequency pen users such as students, office workers, designers, and those recovering from hand injuries, grip comfort and fatigue relief capabilities have become core indicators for evaluating the practicality of pen tools.
[0003] In existing technologies, grip is typically optimized by increasing surface friction (such as through texture design), uniformly thickening the pen barrel, or adding wavy grooves for static support. However, pen caps cannot distribute local pressure in real time, resulting in an inability to dynamically respond to the micro-movements and pressure changes of the user's fingers during writing. This necessitates frequent adjustments to the user's grip to alleviate fatigue. Furthermore, current pen caps are all of fixed sizes, making it difficult to adapt to the needs of users with different hand shapes (such as children and adults). Prolonged use of mismatched pen caps forces the hand muscles to maintain an unnatural posture, which also exacerbates fatigue. Utility Model Content
[0004] In view of the shortcomings of the prior art mentioned in the background section, this utility model proposes a shock-absorbing pen cover.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A shock-absorbing pen cover includes a pen cover body fitted onto a pen barrel. The pen cover body includes a first hollow layer and a second hollow layer. The second hollow layer is disposed within the first hollow layer and is connected to the first hollow layer as a whole through a connecting part.
[0007] Furthermore, a plurality of first hollow holes located on the first hollow layer and a plurality of second hollow holes located on the second hollow layer are arranged alternately along the radial direction of the pen cap body;
[0008] The first and second hollow holes, which have at least partial overlap in the axial projection of the pen cap body, share at least a portion of the connecting part.
[0009] Furthermore, the connecting portion overlaps with the first hollow layer on the axial projection of the pen cap body.
[0010] Furthermore, the thickness of the second perforated layer is greater than that of the first perforated layer.
[0011] Furthermore, the first and second hollow holes are rhomboid in shape with rounded edges, and one first hollow hole is correspondingly set with four second hollow holes, and one second hollow hole is correspondingly set with four first hollow holes.
[0012] Furthermore, it also includes a first end and a second end, which are located on both sides of the axial end of the pen cap body, respectively;
[0013] The first hollow layer, the second hollow layer, and the connecting portion extend from the first end to the second end.
[0014] Furthermore, the radial width of the first end gradually decreases from one side close to the pen cap body to the other side.
[0015] Furthermore, the outer diameter of the pen cap body in the middle along the axial direction is larger than the outer diameters at both ends.
[0016] Furthermore, the first hollow layer is formed by several ribs overlapping each other, and adjacent ribs are connected by corner portions, which protrude from the first hollow layer.
[0017] Furthermore, the hardness of the second perforated layer is greater than that of the first perforated layer and the connecting portion.
[0018] In summary, compared with the prior art, the present invention has at least the following beneficial effects:
[0019] This utility model provides a shock-absorbing pen sleeve, including a pen sleeve body fitted onto the pen barrel. The pen sleeve body includes a first hollow layer and a second hollow layer. The second hollow layer is disposed within the first hollow layer and connected to the first hollow layer as a whole through a connecting part. When the user squeezes the shock-absorbing pen sleeve, the interaction force between the hand and the pen barrel is transmitted through the first hollow layer, the connecting part, and the second hollow layer due to the double-layer hollow design. During writing, the dynamic transmission between the various parts can transform localized force into multi-directional dispersed force, effectively reducing the vibration felt by the hand during writing, thereby reducing hand fatigue and improving user comfort. In addition, through the double-layer hollow structure, the shape of the shock-absorbing pen sleeve can undergo a certain degree of elastic change according to the grip force applied by different users' hands, thus being compatible with different hand shapes. It eliminates the need to customize the pen sleeve size according to the user's hand shape and does not limit the specific grip position on the pen sleeve, effectively improving the versatility of the shock-absorbing pen sleeve.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] As attached Figure 1 As shown, this utility model provides a shock-absorbing pen sleeve, including a pen sleeve body 1 fitted onto the pen barrel. The pen sleeve body 1 includes a first hollow layer 11 and a second hollow layer 12. The second hollow layer 12 is disposed within the first hollow layer 11 and is connected to the first hollow layer 11 as a whole through a connecting part 13. When installed on the pen barrel, the second hollow layer 12 contacts the outer wall of the pen barrel, and the outer wall of the first hollow layer 11 faces the user. Specifically, when the user writes, the hand contacts the outer wall of the first hollow layer 11. The first hollow layer 11 transmits the pressure it receives to the connecting part 13. Then, the connecting part 13 converts the pressure into a multi-directional dispersed force and transmits it to the second hollow layer 12, and finally to the pen barrel. Conversely, the vibration generated during writing is gradually buffered through the pen barrel, the second hollow layer 12, the connecting part 13, and the first hollow layer 11 before being transmitted back to the user's hand.
[0031] Therefore, the shock-absorbing pen cap of this utility model, by setting up a double hollow layer and a connecting part 13 connecting the two, can dynamically transfer the force between the parts during writing, transforming local force into multi-directional dispersed force, effectively reducing the vibration felt by the hand during writing, thereby reducing hand fatigue and improving user comfort, allowing users to hold the pen for extended periods. Furthermore, due to its double-layer hollow structure, when the shock-absorbing pen cap is compressed during writing, the first hollow layer 11, the connecting part 13, and the second hollow layer 12 can undergo slight deformation. Therefore, the shape of the shock-absorbing pen cap can elastically change to a certain extent according to the grip force applied by different users' hands, thus being compatible with different hand shapes. It eliminates the need to customize the pen cap size according to the user's hand shape or limit the specific grip position on the pen cap, effectively improving the versatility of the shock-absorbing pen cap.
[0032] In some embodiments of this utility model, as shown in the appendix Figure 1 and attached Figure 3As shown, a plurality of first hollow holes 111 on the first hollow layer 11 and a plurality of second hollow holes 121 on the second hollow layer 12 are arranged in a staggered pattern along the radial direction of the pen cap body 1. The first hollow holes 111 and the second hollow holes 121, which have at least partial overlap in the axial projection of the pen cap body 1, share at least a portion of the connecting portion 13. By forming a support structure similar to a cross network, the vibrations received during writing can be more effectively dispersed along the connecting portion 13 to the first hollow layer 11 and the second hollow layer 12, achieving a shock-absorbing effect. Furthermore, compared to an aligned double-layer hollow structure, the staggered double-layer hollow structure can further avoid stress concentration. When subjected to hand pressure, it reduces the relative offset between the first hollow layer 11 and the second hollow layer 12, enhances the structural strength of the shock-absorbing pen cap, and thus enhances the deformation resistance of the shock-absorbing pen cap, preventing local collapse or excessive deformation during use due to a large hollow area.
[0033] In some embodiments of this utility model, the connecting part 13 and the first hollow layer 11 overlap on the axial projection of the pen cap body 1, which can shorten the force transmission path between the hand, the first hollow layer 11, the connecting part 13, the second hollow layer 12 and the pen barrel, thereby quickly dispersing the force transmitted between the first hollow layer 11 and the second hollow layer 12, so as to further reduce the continuous vibration of the hand during writing.
[0034] In some embodiments of this utility model, as shown in the appendix Figure 3 As shown, to further enhance the structural strength of the shock-absorbing pen cap, the thickness of the second hollow layer 12 is greater than that of the first hollow layer 11. The thicker second hollow layer 12, located between the pen barrel and the first hollow layer 11, forms an internal rigid support frame, enabling the shock-absorbing pen cap to withstand greater external pressure from the user and repeated forces during writing, making it less prone to deformation.
[0035] In some embodiments of this utility model, as shown in the appendix Figure 1 and attached Figure 3 As shown, the first hollow hole 111 and the second hollow hole 121 are rhomboid in shape with rounded edges. When subjected to external forces and vibrations, various forces and vibrations can be transmitted more smoothly from the diagonal of the first hollow hole 111 and the second hollow hole 121 to the connecting part 13. Furthermore, one first hollow hole 111 is correspondingly arranged with four second hollow holes 121, and one second hollow hole 121 is correspondingly arranged with four first hollow holes 111, so as to achieve the effect of two hollow layers being evenly and alternately arranged. This allows various forces and vibrations generated during writing to be evenly distributed and transmitted along each hollow hole, further improving the shock absorption effect of the pen cap. As a result, the user can reduce the vibration felt by the hand when writing, improve the grip comfort, and avoid hand fatigue caused by prolonged writing, regardless of where the pen cap is held.
[0036] In some embodiments of this utility model, as shown in the appendix Figure 1 and attached Figure 3 As shown, the shock-absorbing pen cap also includes a first end 2 and a second end 3, which are located on opposite sides of the axial end of the pen cap body 1. A first hollow layer 11, a second hollow layer 12, and a connecting portion 13 extend from the first end 2 to the second end 3. The first end 2 and the second end 3 restrict the axial movement of the shock-absorbing pen cap on the pen barrel, making it more stably fixed to the pen barrel and less prone to shifting up and down during writing.
[0037] In some embodiments of this utility model, as shown in the appendix Figure 1 and attached Figure 3 As shown, the radial width of the first end 2 gradually decreases from one side near the pen cap body 1 to the other side, so that when it is fitted onto the pen barrel, the first end 2 forms a natural transition with the pen barrel near the pen tip, ensuring that the hand is not disturbed by the protruding part of the first end 2 when adjusting the grip position during writing, thus improving the user's grip comfort.
[0038] In some embodiments of this utility model, as shown in the appendix Figure 1 and attached Figure 3 As shown, the outer diameter of the pen cap body 1 in the middle along the axis is larger than the outer diameters at both ends. This is because the wider middle part can better adapt to the curvature of the user's hand, providing a more natural writing angle and effectively reducing fatigue.
[0039] In some embodiments of this utility model, as shown in the appendix Figure 1 and attached Figure 2 As shown, the first hollow layer 11 is formed by overlapping several ribs 112. Adjacent ribs 112 are connected by corner portions 113. The corner portions 113 protrude from the first hollow layer 11. The several corner portions 113 can enhance the roughness of the contact surface between the first hollow layer 11 and the user's hand, thereby increasing the friction between the user and the hand when the user holds the shock-absorbing pen cap, making the grip more stable during writing. Even when the user's hands are sweaty, it can prevent the hand from slipping between the hand and the shock-absorbing pen cap.
[0040] In some embodiments of this utility model, the hardness of the second hollow layer 12 is greater than that of the first hollow layer 11 and the connecting part 13. Therefore, the second hollow layer 12 has higher strength and resistance to deformation, enabling the second hollow layer 12 to provide stable support for the first hollow layer 11.
[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
