Description

Technical Field

[0001] This utility model relates to the field of notebook technology, and in particular to a ring notebook with an adjustable inner diameter. Background Technology

[0002] There are many types of common laptops, such as classroom laptops for students and meeting laptops for professionals. Some laptops also have auxiliary components, such as a ring holder, which makes the laptop less likely to slip during use. However, in actual use, we have found that the inner diameter of the traditional ring holder is difficult to adjust flexibly according to the user's actual finger size. This means that the ring holder can only meet the needs of a small group of people. People with larger fingers cannot use it because it is difficult to insert their fingers into the ring. This greatly limits the practical application of the ring and the laptop, and causes great inconvenience to users' daily use. Moreover, replacing it with another ring increases the cost and it is easy to lose it.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0022] An adjustable inner diameter ring notebook includes a base 1, a rotating disk 2 rotatably mounted on the bottom of the base 1, rotating shafts 3 embedded on both sides of the rotating disk 2, positioning grooves 4 evenly spaced on the surface of the rotating shafts 3, four movable cavities 5 on the surface of the base 1, limiting grooves 9 on both sides of the inner cavity of each movable cavity 5, sliding blocks 6 slidably mounted inside the movable cavities 5 and limiting grooves 9, a spring 8 fixedly connected to the top of each sliding block 6, the end of the spring 8 away from the sliding block 6 fixedly connected to the inner wall of the movable cavity 5 and limiting groove 9, and a positioning clip 7 adapted to the corresponding positioning groove 4 fixedly connected to the bottom of each sliding block 6.

[0023] This invention features a structural design that allows for flexible adjustment of the inner diameter based on the actual size of the user's fingers. When the user's fingers are thin, the inner diameter of the ring can be reduced, and when the user's fingers are thick, the inner diameter of the ring can be increased. This design can meet the needs of people with different finger sizes, greatly improving the convenience of daily use of the laptop and enhancing the user's actual experience.

[0024] The specific usage process is as follows: First, the ring in this solution adopts an open structure design, which has a certain degree of self-adjustability in the initial state. Because the clamp 10 is made of plastic, it has a certain degree of toughness, which can meet the usage needs to a certain extent. For example, it can achieve adaptive adjustment when the difference in finger thickness is not large. Considering that the toughness of plastic material is limited, forcibly inserting a thicker finger can easily cause the clamp 10 to break. Therefore, the clamp 10 can also be adjusted by flipping it outward. In this way, the distance between the two clamps 10 can be increased, and vice versa, to meet more usage needs. When adjusting the inner diameter of the ring, the operation is as follows: first, push the sliding block 6 upward. The sliding block 6 in the movable cavity 5 The sliding block 6 slides upwards, while its two sides slide within the limiting groove 9. The limiting groove 9 limits the sliding block 6, preventing it from falling out of the movable cavity 5. Simultaneously, as the sliding block 6 slides upwards, it compresses the spring 8, causing the positioning strip 7 to move out of its corresponding positioning groove 4. Once the sliding block 6 and positioning strip 7 are inside the movable cavity 5, the clamp 10 can rotate. The clamp 10 is then flipped outwards, causing the rotating shaft 3 to rotate on the rotating disk 2. The clamp 10 stops when the distance between the two clamps 10 is adjusted to a suitable level. The sliding block 6 is then released, and under the action of the spring 8, it pops out of the movable cavity 5. Simultaneously, the positioning strip 7 also moves out of the movable cavity 5 along with the sliding block 6. The ring is then inserted into the positioning groove 4 at its current position, thus fixing the rotating shaft 3 and the clamp 10 at their current positions. This allows the inner diameter of the ring to meet current usage requirements. Furthermore, the spacing between the clamps 10, i.e., the inner diameter of the ring, can be adjusted. Following the above operation, the two clamps 10 are flipped towards each other, reducing the spacing between them, thus decreasing the inner diameter of the ring. It should be noted that four sliding blocks 6 and four positioning clips 7 are provided, one every ninety degrees. Positioning clips 7 and sliding blocks 6 not inserted into the positioning groove 4 will be squeezed into the inner cavity of the movable cavity 5 by the rotating disk 2. This allows for adjustment of the ring's rotation angle, enabling the ring to rotate on the base 1 via the rotating column 11. To meet diverse user needs and enhance convenience, the design incorporates an adjustable inner diameter that allows for flexible adjustment based on finger size. For thinner fingers, the inner diameter can be reduced; for thicker fingers, it can be increased. This caters to users with varying finger sizes, significantly improving the user experience and convenience of daily laptop use. It's worth noting that the ring's rotation angle is also adjusted by inserting the cover 17 into the positioning slot 4. This design only shows four adjustable angles; however, more adjustable angles can be added based on actual usage requirements simply by increasing the number of sliding blocks 6 and positioning clips 7, resulting in low production costs.

[0025] The bottom of the rotating shaft 3 is fixedly connected to a hoop 10 located outside the rotating disk 2, and a protective pad is provided on the inner side of the hoop 10.

[0026] Specifically, the hoop 10 is designed such that two hoops 10 form a ring into which the user's fingers can be inserted, and the inner side of the hoop 10 is provided with a pad to avoid injury and discomfort to the fingers, thus protecting the user's fingers and providing convenience for the user's work.

[0027] A rotating column 11 is fixedly connected to the top of the rotating disk 2. The rotating column 11 is inserted into the interior of the base 1 and rotates inside the base 1.

[0028] Specifically, the rotating column 11 is rotatably installed inside the base 1, so that the rotating disk 2 can rotate on the base 1 with the help of the rotating column 11, thereby realizing the angle adjustment, meeting more user needs, and providing convenience for users' work.

[0029] The top of the rotating disk 2 is provided with multiple positioning holes 12, and the bottom of the base 1 is provided with multiple sliding holes 13. The inner cavity of the sliding hole 13 is slidably installed with a positioning pin 14 that matches the positioning hole 12. The top end of the positioning pin 14 is fixedly connected with a spring 15, and the end of the spring 15 away from the positioning pin 14 is fixedly connected to the inner wall of the sliding hole 13.

[0030] Specifically, the positioning hole 12, sliding hole 13, positioning pin 14, and spring 15 are designed so that the positioning hole 12 and positioning pin 14 are used to position the rotating disk 2 after it has rotated by an angle. This can further improve the stability of the ring after it has rotated by an angle. Furthermore, there is no conflict between the positioning hole 12 and the positioning clip 7 and the positioning groove 4, which provides more convenience and assistance for the user.

[0031] The base 1 is provided with a bottom cover 16 on its top, and the base 1 is glued to the bottom cover 16.

[0032] Specifically, regarding the base 1 and the bottom cover 16, the base 1 is glued to the bottom cover 16 to ensure that the ring will not fall off, providing convenience for users. It should be noted that it can also be designed as a magnetic installation method, making it easy for users to remove the ring and meet more user needs.

[0033] The back cover 16 has a writing page 18 at the top, and the writing page 18 has a cover 17 at the top. The back cover 16, the cover 17, and the writing page 18 are sewn together on one side.

[0034] Specifically, the back cover 16, front cover 17, and writing page 18 are designed to protect the writing page 18. The back cover 16 and front cover 17 are used to protect the writing page 18 from being spied on and to prevent the writing page 18 from getting wet, thus providing convenience for the user.

[0035] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
