[0083] like Figure 1-10 The present patent discloses a writing pen with a movable clip assembly. The writing pen includes a pen barrel assembly 10 connected to a clip assembly 20. The clip assembly 20 includes a decorative element 21, a return spring 22, and a clip housing 23. The clip housing 23 includes a hollow groove 232, in which the return spring 22 is accommodated. One end of the return spring 22 abuts against the clip housing 23, and the other end abuts against the decorative element 21. The decorative element 21 is at least partially disposed on the surface of the clip housing 23. The user drives the decorative element 21 to slide within the hollow groove 232, compressing the return spring 22. The hollow groove is a long, hollow groove inside the clip housing.
[0084] Working principle: The decorative piece 21 slides upwards in the hollow groove 232 to compress the return spring 22. When the decorative piece 21 is at the bottom of the hollow groove 232, i.e., closest to the pen tip 121, the return spring 22 is relaxed or slightly compressed. As the decorative piece 21 slides upwards, i.e., towards the pen cap 11, the degree of compression of the return spring 22 gradually increases with the increase of displacement, until the decorative piece 21 reaches the top of the hollow groove 232, i.e., near the pen cap 11, where the return spring 22 is deeply compressed. At this point, if the user releases the decorative piece 21 to stop the external force driving it, the decorative piece 21 will immediately rebound back to the bottom under the elastic action of the return spring 22. In this case, the user can release the decorative piece 21 at any position where it slides upwards to stop the external force driving it, thus allowing the decorative piece 21 to rebound back to the bottom at any position under the elastic action of the return spring 22.
[0085] <Accessories>
[0086] The decorative part 21 includes an I-shaped portion, which includes an outer sliding part 211 and a sleeve part 213. The sleeve part 213 is used to abut against the return spring 22 in the hollow groove 232. The outer sliding part 211 is connected to the sleeve part 213 and is disposed on the surface of the pen clip housing 23, so that the user can directly contact and drive the outer sliding part 211 to slide from bottom to top on the surface of the pen clip housing 23. The outer sliding part 211 drives the sleeve part 213 to slide together. When the sleeve part 213 slides, the return spring 22 it abuts against is in a compressed state.
[0087] Specifically, the outer slider 211 is at least partially a protruding structure relative to the pen clip housing 23. On the one hand, it makes it easy for the user to locate the position of the outer slider 211 by touch. On the other hand, it also makes it easy to form a staggered sense of layering with other structures of the pen clip assembly 20, which has a good decorative effect.
[0088] Specifically, the accessory 21 also includes a clamping part 212, which is located on one side near the pen barrel assembly 10 and has a raised structure to facilitate clamping and positioning the writing pen at any time. In addition, the clamping part 212 slides upward together with the outer slider 211, making it easy to adjust the clamping position according to the external environment.
[0089] Specifically, the clamping part 212 and the I-shaped part are integrally molded.
[0090] Specifically, the clamping part 212 has a hemispherical structure.
[0091] Specifically, the outer sliding component is equipped with an anti-slip structure. This anti-slip structure can be made of an anti-slip material, with at least the portion of the outer sliding component in contact with the user being made of an anti-slip material such as rubber. Alternatively, the anti-slip structure can be an anti-slip textured structure (not shown in the figure) on the surface of the outer sliding component. This can be achieved by electrostatic discharge or engraving to form raised patterns or grooves on the outer sliding component, increasing friction when the user applies external force to drive the outer sliding component and preventing operational errors due to the user's slippery or sweaty hands.
[0092] <Pen clip housing>
[0093] The pen clip housing 23 includes a hollow groove 232, a guide strip 233, a sliding groove 234, and a spring contact portion 231. The sleeve portion 213 slides along the length direction of the pen barrel assembly 10 under the action of the guide strip 233 to compress the return spring 22. The sliding groove 234 is located close to the hollow groove 232, and the outer slider 211 slides along the length direction of the pen barrel assembly 10 in the sliding groove 234.
[0094] Specifically, the diameter of the return spring 22 is larger than the inner diameter of the sliding groove 234. The spring contact portion 231 and the sliding groove 234 are arranged close to the return spring 22 to form a part that accommodates the return spring 22, thereby limiting the lateral movement of the return spring 22 during compression. The length of the spring contact portion 231 is 0.35 times the length of the hollow groove 232. During compression, when the return spring 22 is subjected to pressure from the upward sliding of the sleeve portion 213, due to the elastic material of the return spring 22 itself, excessive compression may generate a lateral force, i.e., a force perpendicular to the length direction of the pen assembly 10. This lateral force will cause the return spring 22 to bend laterally, thereby affecting the fit between the various structures and making the return spring 22 susceptible to damage. This patent forms a relatively closed accommodating space at the upper end of the hollow groove 232 by the spring contact portion 231 and the sliding groove 234, even when the return spring 22 is deeply compressed (e.g., ...). Figure 9-10 As shown, the limit spring 22 only extends and retracts in the length direction of the pen assembly 10.
[0095] <Pen barrel assembly>
[0096] The pen assembly 10 includes an upper pen barrel 13, a lower pen barrel 14, a pen barrel connecting part 15, a pen refill 12, a press assembly 17, a pen cap connecting seat 16, and a pen cap 11. The upper pen barrel 13 and the lower pen barrel 14 form part of the user's handheld grip and are connected by the pen barrel connecting part 15. The press assembly 17 is connected to the pen refill 12, and the pen cap 11 is nested in the pen cap connecting seat 16 to switch between writing and resting states.
[0097] When the user needs to use the pen for writing, they can press the pen cap 11 from the top to the bottom. The pen cap 11 moves the snap-action component 17 and the pen refill 12 downwards together, allowing the snap-action component 17 to engage with the pen barrel. The pen tip 121 extends from the inside of the pen barrel to the outside. At this point, the pen cap 11 moves upwards a short distance to the middle position and is then engaged. The snap-action component 17 and the pen refill 12 are both in a relatively stationary state, and the user can begin writing. The snap-action component 17 in this patent can be any type of snap-action component in the prior art. When the user needs to switch the pen to rest mode, they can continue pressing the pen cap 11 from the middle position to the bottom to release the snap-action component 17 from the inside of the pen barrel. The pen cap 11, the snap-action component 17, and the pen refill 12 move upwards together to the top, and the pen tip 121 retracts from the outside of the pen barrel to the inside.
[0098] Specifically, the pen cap connector 16 and the spring contact part 231 are integrally formed.
[0099] Specifically, the pen clip housing 23 also includes a connecting part 24, which is used to connect the pen clip assembly 20 to the pen barrel assembly 10. The connecting part 24 can be configured as a movable connection structure or a fixed connection structure.
[0100] More specifically, the movable connection structure can be an interference fit connection or a threaded connection, etc.
[0101] More specifically, the fixed connection structure can be a structure in which the pen clip assembly 20 and the pen barrel assembly 10 are integrally formed, or a fixed connection method such as welding.
[0102] Specifically, one end of the return spring 22 abuts against the connecting part 24. During the compression of the return spring 22, the position of the connecting part 24 is fixed relative to the return spring 22, while the other end of the return spring 22 is compressed under the sliding of the sleeve part 213.
[0103] This patent offers a novel and innovative design concept, effectively addressing the pain points of traditional pen clips being limited in function and fixed in form. Through structural design, it allows for free adjustment of the clip's angle and position, significantly improving the product's adaptability to different usage scenarios. The modular and detachable decorative component design empowers users to customize the appearance, making pens a vehicle for expressing personal style. Simultaneously, the dynamic interactive experience brought by the movable structure further enhances the emotional connection between the product and the user, injecting new vitality into the stationery market. This technological innovation not only meets contemporary consumers' pursuit of high-quality, differentiated products but also provides a new technological path for the intelligent and creative development of the stationery industry.
