Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] Example:

[0025] See Figure 1 - Figure 6 In this embodiment, a corn pen is involved, which is specifically used for daily writing and provides a detachable and assembleable appearance decoration to achieve personalized customization and entertainment effect. Specifically, it includes a pen barrel 1 and a pen core 2. The pen barrel 1 is provided with a bushing 3 and a fixing sleeve 4 from the inside to the outside. A decorative sleeve 5 composed of corn kernel-like particles 51 is detachably connected to the outside of the fixing sleeve 4. One end of the bushing 3 is connected and fixed to the fixing sleeve 4, and the other end is provided with a limiting end cap 32 to prevent the decorative sleeve 5 from falling off the fixing sleeve 4.

[0026] Specifically, in this embodiment, the present invention provides a semi-open decorative cavity for the pen barrel 1 through the bushing 3. Users can install decorative sleeves 5 of different shapes or colors onto the fixing sleeve 4, and then limit the decorative sleeves 5 through the limiting end cap 32 of the fixing sleeve 4 to achieve DIY replacement of the decorative sleeves 5. In this embodiment, the decorative sleeve 5 is composed of corn kernel-like particles 51, forming a "corn segment" shape on the outer part of the pen barrel 1. Some of the corn kernels 51 use fluorescent material, which can produce a luminous effect at night or in the dark, enhancing interest and differentiation. This makes the pen barrel 1 aesthetically pleasing, satisfying users' personalized customization needs while also providing a fun user experience. Furthermore, the decorative sleeve 5 of this invention adopts a detachable structure design, making it easy to remove and clean separately.

[0027] The pen barrel 1 and the bushing 3 are snapped together and fixed. The outer wall of the pen barrel 1 and the inner wall of the bushing 3 are provided with mutually engaging and compatible first limiting protrusions 11. Specifically, as shown... Figure 3As shown, during injection molding, two annular first limiting protrusions 11 are integrally formed on the outer wall of the pen barrel 1, and matching protrusions are set at corresponding positions on the inner wall of the bushing 3. During assembly, utilizing the elasticity of the material itself, the pen barrel 1 is pressed into the bushing 3, and the protrusions of the bushing 3 will pass over one protrusion of the barrel and finally fall between the two protrusions to form a lock. The bushing 3 and the fixing sleeve 4 are connected and fixed by a threaded structure. The end of the bushing 3 away from the limiting end cap 32 is provided with an external thread 31, and the end of the fixing sleeve 4 is provided with an internal thread 41 that is adapted to connect with the external thread 31. This allows the fixing sleeve 4 to be firmly fixed to the pen body, effectively preventing the decorative sleeve 5 from falling off.

[0028] See Figure 4 and Figure 5 The fixing sleeve 4 has several sets of equally spaced sliding grooves 42 on its outer circumference, and the corn kernel-like particles 51 are provided with protruding structures 52 that slide and adapt to the sliding grooves 42. Specifically, the outer wall of the fixing sleeve 4 has several sets of sliding grooves 42 (the cross-section can be "T" shaped or dovetail shaped) along its axial direction. Correspondingly, the inner side of each corn kernel-like particle 51 (i.e., the side that is in contact with the fixing sleeve 4) is provided with a protruding structure 52 that matches its shape. This makes installation convenient; the user only needs to align the protruding structure 52 of the particle 51 with the opening end of the sliding groove 42 and push it in.

[0029] To further reduce assembly difficulty and encourage creativity, this embodiment pre-assembles individual corn kernel-like particles 51 into modular blocks 53 with a specific shape. See also Figure 4 The decorative set 5 is composed of several sets of modular blocks 53, which are arranged in different shapes using varying numbers of corn kernel-like particles 51. Users no longer need to manipulate each small particle 51 individually; instead, they can directly assemble the modular blocks 53. This greatly improves assembly efficiency and convenience, and helps create decorative sets 5 in various forms (see [link]). Figure 5 This resulted in the missing piece 51 in five locations of the decorative sleeve, effectively enhancing the product's appeal. (See also...) Figure 6The assembly block 53 is formed by three horizontally arranged groups of particles 51 and three vertically arranged groups of particles 51 in an "L" shape, with one group of particles 51 shared at the intersection. The slide groove 42 has 12 sets, and its length is equal to the thickness of five groups of corn kernel-like particles 51. Through the staggered splicing of multiple sets of assembly blocks 53, they can completely fill the slide groove 42 after sliding in, resulting in a "full" structure of five layers of particles 51, each with 12 groups of particles 51. The uniform "L" shape of the assembly blocks 53 reduces mold costs during manufacturing and ensures a DIY experience for users. To protect the pen refill 2 and prevent ink evaporation, this invention also includes a pen cap 6, which is inserted into and adapted to the pen barrel 1. Second limiting protrusions 12 are provided on the outer wall of the pen barrel 1 and the inner wall of the open end of the pen cap 6, respectively, for mutual locking. When closed, the two lock together through elastic deformation.

[0030] The limiting end cap 32 is provided with a protrusion 33, which can be conical, hemispherical, or cylindrical. When the pen cap 6 is fully closed, if the user rotates the pen cap 6 horizontally, the pen cap 6 will drive the limiting end cap 32, and then drive the entire pen barrel 1 (decorative sleeve 5) to rotate through the bushing 3 and the fixing sleeve 4, forming a spinning effect similar to a "spinning top". After receiving the product, the user can first unscrew the fixing sleeve 4, and then select different colors or shapes of "L"-shaped combination blocks 53 according to personal preference, aligning the protruding structure 52 on the back of each block with the sliding groove 42 on the fixing sleeve 4, and sliding them in one by one. When all the sliding grooves 42 are filled or a satisfactory pattern is formed, the fixing sleeve 4 is then tightened back onto the outer thread 31 of the bushing 3 through the internal thread 41. At this point, a completely personalized corn pen is assembled. For daily use, simply remove or cover the pen cap 6. In leisure time, the user can also rotate the closed pen cap 6 to enjoy the dynamic effect of the rotating decorative sleeve 5. In addition, the end of the pen cap 6 is provided with a hanging loop 61, which enhances the portability of the pen. Users can easily tie a lanyard to it and hang it around their neck, on their backpack or keychain, making it less likely to be lost and convenient to access at any time.
