[0050] Embodiment 1:

[0051] This embodiment aims to further demonstrate the application and working principle of the card sleeve structure for paper display in work scenarios, especially in office environments. In modern office environments, efficient information transmission and convenient document display are crucial to improving work efficiency.

[0052] Application scenario 1: Temporary display in conference room

[0053] In the conference rooms of enterprises and institutions, it is often necessary to temporarily display meeting agendas, important documents or report contents. The traditional approach may be to use tape, thumbtacks or special display boards, but these methods will either damage the wall or be inconvenient to use.

[0054] By using the card sleeve structure for paper display in this embodiment, employees can easily insert the paper needed for the meeting into the corner limit cavity 4 of the card sleeve ring, and then use the permanent magnet sheet 6 of the card sleeve structure to adsorb it on any metal surface, such as a refrigerator door, a filing cabinet or a special metal display board. In this way, not only damage to the wall is avoided, but also the flexibility and efficiency of the display are greatly improved.

[0055] Application scenario 2: Personal reminder at the desk

[0056] On their desks, employees often need to check some important reminders, to-do lists, or temporary notes. If these papers are placed randomly, they are easy to get lost or messed up.

[0057] Using the card sleeve structure of this embodiment, employees can neatly display these papers on the edge of the desk or any convenient viewing position. Since the card sleeve structure allows the four corners of the paper to be firmly fixed, the papers can remain flat and not easily moved even in busy work.

[0058] How it works

[0059] The working principle of the card sleeve structure of the paper display of this embodiment is simple and efficient. After the four corners of the paper are inserted into the corner stopper cavity 4 of the card sleeve ring, the paper is firmly positioned in the appropriate position due to the combined effect of the card sleeve ring and the corner stopper plate 3. At the same time, the multifunctional corner hole 5 on the support back plate 2 not only provides additional support for the paper, but also allows the user to make fine adjustments as needed.

[0060] In addition, by providing a permanent magnet sheet 6 on the back side of the supporting back plate 2, the sleeve structure of this embodiment can be easily adsorbed on any metal surface, further expanding its application range and ease of use.

[0061] The card sleeve structure for paper display in this embodiment effectively solves a series of problems of paper display in the office environment through its innovative design and simple working principle. It not only improves the efficiency of information transmission, but also improves the neatness and professionalism of the office environment. The examiner can clearly see that the utility model does have great innovative value and solves very important problems in practical work.

[0062] Embodiment 2:

[0063] This embodiment provides a specific application method of a card sleeve structure for paper display, which is particularly suitable for paper display needs in the field of education.

[0064] In educational scenarios, teachers often need to post students' homework, activity notices, or teaching materials on the walls of classrooms for students to refer to. Traditional display methods may involve complicated installation steps or the use of specific display boards, which increases the cost of use and the complexity of operation.

[0065] In view of this problem, the present embodiment provides a card sleeve structure for paper display, which has a simple structure, is easy to use, and can adapt to various types of paper. Specifically, the card sleeve structure includes a square card sleeve ring 1, a support back plate 2, and an angle stop plate 3. The square card sleeve ring 1 has an annular bottom end face and an annular top end face, and the support back plate 2 is fixed on the annular top end face. The angle stop plate 3 is located at the four corners of the square card sleeve ring 1, and an angle stop cavity 4 is formed between the support back plate 2 and the card sleeve ring 1.

[0066] When in use, the teacher can choose a transparent plastic plate 8 with a certain hardness, the size of which matches the A4 paper 9 to be displayed. The transparent plastic plate 8 is placed overlapping with the A4 paper, and it is ensured that the transparent plastic plate 8 is located at the top to form a combination 10 to be positioned of the paper and the transparent plastic plate 8. At the same time, the transparent plastic plate 8 has a certain hardness, so that it can play a certain non-deformation support effect, but because of its relatively thin thickness, it can be slightly deformed to a certain extent, so that the four corners can be inserted after deformation. Next, the two left corners of the combination 10 to be positioned are respectively inserted into the two corner limit cavities 4 near the left side of the square clamp ring 1. Since both the transparent plastic plate 8 and the A4 paper have a certain deformability, the combination 10 to be positioned can be deformed by slightly squeezing it, so that the two corners on the right are also smoothly inserted into the corresponding corner limit cavities 4. When the transparent plastic plate 8 returns to its natural unfolded state, the four corners will rebound and be firmly positioned in the corner limit cavity 4, and the transparent plastic plate 8 can also be replaced with a new transparent plastic plate 8 with a relatively low cost after long-term use, so as to achieve a use effect that is conducive to long-term clear display.

[0067] In addition, the support back plate 2 is also provided with multifunctional corner holes 5, which not only facilitate the installation and adjustment of the corner stop plate 3, but also provide users with additional convenience and expandability. For example, when the positioning assembly 10 needs to be further fixed, a patch can be added to the corner stop plate 3 through the multifunctional corner hole 5 or a permanent magnet can be used for adsorption to enhance the positioning effect.

[0068] The card sleeve structure of the paper display of this embodiment not only simplifies the paper display process, but also improves the stability and flexibility of the display. Teachers can easily post homework, notices or teaching materials on the wall of the classroom for students to refer to at any time. At the same time, the card sleeve structure can also be adjusted according to the thickness and type of paper to meet different display needs.

[0069] Embodiment 3:

[0070] This embodiment further describes the detailed application and functional expansibility of the multifunctional corner hole 5 in the card holder structure for paper display, and particularly emphasizes its role in adapting to papers of different thicknesses, providing avoidance space, and enhancing the positioning effect.

[0071] First, regarding the avoidance function of the multifunctional corner hole 5. When inserting the two left corners of the combination to be positioned (a combination of paper and a transparent plastic plate) into the two corner limit cavities 4 on the left side of the square clamp ring 1, in order to facilitate the smooth insertion of the two right corners of the combination to be positioned into the two corner limit cavities 4 on the right side, the user can squeeze the combination to be positioned by hand to cause it to slightly shift to the left and deform. In this process, the design of the multifunctional corner hole 5 plays a key role. Since the multifunctional corner hole 5 is located at a position corresponding to the corner limit cavity 4 on the supporting back plate 2, its existence provides additional space for the combination to be positioned when it is deformed, so that the two right corners can be more smoothly inserted into the corner limit cavity 4 without being hindered.

[0072] Secondly, the multifunctional corner hole 5 also plays an important role in adjusting the thickness of the corner limit cavity 4 to adapt to different thicknesses of paper. For thinner A4 paper 9, the thickness of the corner limit cavity 4 may be relatively large, resulting in insufficient stability after the paper is inserted. At this time, a patch known to a person skilled in the art in the prior art can be added to the corner limit plate 3 through the multifunctional corner hole 5 to reduce the actual thickness of the four corner limit cavities 4 accordingly, so as to better match the thinner A4 paper 9. For thicker paperboard, the patch can be removed through the multifunctional corner hole 5 to increase the thickness of the corner limit cavity 4 to ensure that the paperboard can be firmly inserted and positioned in the corner limit cavity 4.

[0073] Finally, the multifunctional corner hole 5 also provides an expandable positioning enhancement function. When the transparent plastic plate 8 returns to its natural unfolded state after deformation, its four corners will rebound and be positioned in the corner limit cavity 4. In order to further enhance this positioning effect, a metal adsorption structure can be provided on the corner limit plate 3. At this time, through the multifunctional corner hole 5, the user can insert the permanent magnet into the corner limit cavity 4 to adsorb the metal adsorption structure, thereby achieving additional reinforcement of the four corners of the A4 paper 9 and the transparent plastic plate 8 after positioning. This design not only improves the stability of the display, but also provides users with more usage options and flexibility.

[0074] In summary, the card sleeve structure for paper display in this embodiment realizes the functions of smooth insertion of the positioning combination, adaptability to papers of different thicknesses, and enhancement of positioning effect by rationally using the multifunctional corner hole 5. These functions jointly enhance the practicality and convenience of the card sleeve structure, making it have a wider application prospect in the fields of education, office, etc. At the same time, according to the description of this embodiment and the prior art knowledge, ordinary technicians in this field can easily implement and apply this technical solution.
