[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail. This application discloses a loose-leaf notebook. (Refer to...) Figure 1 and Figure 5 A loose-leaf notebook includes an upper fixed shell 1 and a lower fixed shell 2, with notebook paper pages 3 disposed between the upper fixed shell 1 and the lower fixed shell 2. An arc plate 6 is fixedly installed on the left side of the upper fixed shell 1 and the lower fixed shell 2, and a loose-leaf clip 5 is fixedly connected to the right side of the arc plate 6. Limiting components 7 are installed at the top and bottom of the notebook paper pages 3. The limiting component 7 includes a U-shaped plate 701, the surface of which is in close contact with the top and bottom of the notebook paper page 3. A first fixing plate 705 is fixedly installed on the surface of the arc plate 6, and a second fixing plate 706 is fixedly connected to the surface of the U-shaped plate 701. A limiting rod 707 is movably installed on the surface of the second fixing plate 706, and a compression spring 708 is fixedly sleeved on the surface of the limiting rod 707. The upper fixing shell 1 and the lower fixing shell 2 serve as the main frame of the notebook, providing structural support and protection. The fixing design of the upper fixing shell 1 and the lower fixing shell 2 can prevent the notebook paper page 3 from being deformed or falling off due to external pressure during carrying or use. The arrangement of the notebook paper page 3 ensures that the paper is neatly arranged and not easily scattered. The loose-leaf design allows users to freely change or adjust the paper order. The U-shaped plate 701 directly contacts the top and bottom of the notebook paper page 3 and slides and adjusts with the T-shaped block 704 and the displacement groove 703, making it easy to remove and improving binding flexibility.

[0018] Reference Figure 1 and Figure 2The upper fixed shell 1, the lower fixed shell 2, and the left side of the notebook paper page 3 are all provided with round holes 4. The surface of the loose-leaf clip 5 is located inside the round hole 4. The round hole 4 allows the loose-leaf clip 5 to pass through, which simplifies the traditional multi-part locking structure and reduces assembly difficulty and production cost.

[0019] Reference Figure 1 and Figure 4 There are several curved plates 6, and two loose-leaf clips 5 are set at the top and bottom. Through the setting of the loose-leaf clips 5, the upper and lower loose-leaf clips 5 are engaged with the positioning block 8 and the positioning groove 9 to ensure a stable closure and easy operation. The curved design of the loose-leaf clips 5 makes it easy to open and close with one hand, improving the user experience. The setting of the curved plates 6 provides structural support and disperses external forces. The arrangement of multiple curved plates 6 enhances the overall strength and adapts to the needs of loose-leaf notebooks of different sizes.

[0020] Reference Figure 1 and Figure 4 The upper hinge 5 has a positioning groove 9 on its surface, and the lower hinge 5 has a positioning block 8 fixedly embedded on its surface. The positioning block 8 works in conjunction with the positioning groove 9. The positioning structure of the upper and lower hinges 5 ensures accurate alignment when closed, avoids misalignment or loosening, and improves the reliability and aesthetics of closing.

[0021] Reference Figure 1 and Figure 5 Limiting plates 702 are fixedly installed on both the left and right sides of the upper fixed outer shell 1 and the lower fixed outer shell 2. The surface of the limiting plate 702 is provided with a displacement groove 703. Through the setting of the limiting plate 702, it can be used in conjunction with the displacement groove 703. The displacement groove 703 cooperates with the T-shaped block 704 to realize the longitudinal sliding adjustment of the U-shaped plate 701, ensuring that the notebook paper page 3 is aligned and fixed firmly, and at the same time fixing the notebook paper page 3, so that the notebook paper page 3 will not shake randomly.

[0022] Reference Figure 1 and Figure 5 T-shaped blocks 704 are fixedly connected to both sides of the U-shaped plate 701. The T-shaped blocks 704 are used in conjunction with the displacement groove 703. There are several first fixing plates 705. Through the setting of the first fixing plates 705, they can be used in conjunction with the second fixing plates 706 and are fixed on the arc plate 6 and the U-shaped plate 701 respectively. The elastic connection is achieved by the limiting rod 707 and the compression spring 708, which facilitates disassembly and assembly.

[0023] Reference Figure 1 and Figure 5There are several second fixing plates 706. The surface of the limiting rod 707 extends through to the surface of the first fixing plate 705. One end of the compression spring 708 is fixedly connected to the surface of the limiting rod 707, and the other end of the compression spring 708 is fixedly connected to the surface of the first fixing plate 705. Through the setting of the limiting rod 707, it can be used in conjunction with the compression spring 708. The limiting rod 707 passes through the second fixing plate 706 and automatically rebounds through the compression spring 708, providing elastic clamping force, which not only ensures a firm fixation, but also facilitates the user to quickly install and remove paper.

[0024] Working principle: All components are in their initial state. During actual use, when the user opens the hinge 5, the compression spring 708 is compressed, the limiting rod 707 retracts from the first fixing plate 705, and the U-shaped plate 701 moves, separating from the notebook paper page 3. At this time, the notebook paper page 3 is no longer fixed, allowing paper to be removed or added for use. When closing, the hinge 5 locks, and the limiting rod 707, under the action of the compression spring 708, inserts into the first fixing plate 705, fixing the position of the U-shaped plate 701 and ensuring the paper is stable. The U-shaped plate 701 is embedded through the T-shaped blocks 704 on both sides. The displacement groove 703 of the limiting plate 702 allows the U-shaped plate 701 to slide along the displacement groove 703. When the notebook is stored, the U-shaped plate 701 always stays close to the edge of the paper to prevent misalignment and support the notebook paper pages 3, preventing the notebook paper pages 3 from shifting randomly and becoming loose. At the same time, when the user applies force to separate the upper and lower loose-leaf clips 5, the arc plate 6 undergoes elastic deformation, causing the loose-leaf clips 5 to disengage from the locked state. At this time, the notebook paper pages 3 can be freely flipped or replaced. When closed, the positioning block 8 and the positioning groove 9 help the upper and lower loose-leaf clips 5 to be accurately aligned and avoid misalignment. The design of the arc plate 6 makes the notebook easier to lay flat.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
