Detailed implementation manners

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] It should be noted that all the expressions using "first" and "second" in the embodiments of the present utility model are used to distinguish two entities or parameters with the same name but different, so "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present utility model. This will not be elaborated one by one in the subsequent embodiments.

[0026] The directional and positional terms mentioned in the present utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only with reference to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are for explaining and understanding the present utility model, rather than limiting the protection scope of the present utility model.

[0027] Such as Figures 1-4As shown in the figure, an anti - toppling vertical notebook includes a front panel 1 and a back panel 2. The front panel 1 and the back panel 2 have a connection end forming a rotatable connection and a free end away from the connection end. It also includes a flexible belt 3. The flexible belt 3 includes a fixed end and a free end. The fixed end of the flexible belt 3 is fixedly connected to the front panel 1 near the free end. A buckle 4 is fixedly connected to the free end of the flexible belt 3. Blocks are provided on both the outer and inner surfaces of the back panel 2. The buckle 4 and the blocks can form a detachable connection and cooperation.

[0028] Specifically, Figure 2 For the back panel 2 shown in the figure, a first block 5A is provided on its outer surface, and a second block 5B, a third block 5C, and a fourth block 5D are provided on its inner surface. The second block 5B, the third block 5C, and the fourth block 5D are distributed in sequence from the free end to the connection end of the back panel 2. Figure 1 As shown in the figure, it is the open state of the notebook, that is, the inner pages are located outside the front panel 1 and the back panel 2. The buckle 4 is connected and cooperated with the second block 5B. The front panel 1 and the back panel 2 form a triangular support structure with a larger angle, forming an anti - toppling vertical support effect; the buckle 4 can also cooperate with the third block 5C, and the front panel 1 and the back panel 2 form a triangular support structure with a smaller angle; the buckle 4 can also cooperate with the fourth block 5D. As Figure 3 shown in the figure, at this time, the front panel 1 and the back panel 2 are close to each other. The fourth block 5D and the flexible belt 3 form a holding force that keeps the front panel 1 and the back panel 2 close to each other. At this time, the state of the notebook is not suitable for vertical placement and is suitable for being held by hand. At the same time, since the free end of the flexible belt 3 is fixed by the fourth block 5D, it will not swing randomly, and the use feeling is better. Figure 3 As shown in the figure, it is the closed state of the notebook, that is, the inner pages are located inside the front panel 1 and the back panel 2. The buckle 4 is connected and cooperated with the first block 5A. The free end of the flexible belt 3 is fixed by the first block 5A and will not swing randomly, and the use feeling is better. Further, the position where the first block 5A is set makes the flexible belt almost unable to deform, forming a holding force that keeps the front panel 1 and the back panel 2 close to each other. In this way, a holding force for keeping the notebook closed is formed to prevent the inner pages from spreading out, which is suitable for storage.

[0029] A groove 201 for the flexible belt 3 to bypass is provided at the free end of the back panel 2. The setting of the groove 201 prevents the flexible belt 3 from protruding relative to the free end of the back panel 2 when it bypasses, so that the free end of the back panel 2 cannot stably support on a plane, affecting the stability of the notebook during vertical support.

[0030] As Figure 5 、 Figure 6As shown, the circumferential cross-section of the clamping block has two first convex surfaces 501 and a concave surface 502 that smoothly transitions between the two first convex surfaces. A clamping groove adapted to the shape of the clamping block is provided inside the clamping member 4. The circumferential inner wall cross-section of the clamping groove has a smooth second convex surface 401. A part of the second convex surface 401 is adapted to the concave surface 502. When the clamping member 4 and the clamping block form a detachable connection and cooperation, a part of the second convex surface 401 matches the concave surface 502.

[0031] Further, as Figure 5 shown, a first connecting rivet 503 with a large head end at the outer end is fixedly provided on the back surface of the clamping block. A first connecting hole 202 through which the first connecting rivet 503 can pass is provided on the back panel 2. A first limiting plate 504 is further included. The first connecting rivet 503 passes through the first connecting hole 202 and the first limiting plate 504, and its large head end abuts against the first limiting plate 504 for limiting and cooperating. The front panel 1 and the back panel 2 of the notebook are mostly cardboard with a certain thickness. Although the cardboard has a certain strength and is not easily torn, its strength is limited. The clamping block in this embodiment can be stably fixed on the back panel 2 through the first connecting rivet 503 and the first limiting plate 504, forming a relatively large-area matching structure on the back panel 2, so that its fixing structure is not affected by the strength of the back panel 2.

[0032] Further, as Figure 7 shown, a fixing block 6 is fixedly connected to the fixed end of the flexible belt 3. A second connecting rivet 601 with a large head end at the outer end is fixedly provided on the back surface of the fixing block 6. A second connecting hole 101 through which the second connecting rivet 601 can pass is provided on the front panel 1. A second limiting plate 602 is further included. The second connecting rivet 601 passes through the second connecting hole 101 and the second limiting plate 602, and its large head end abuts against the second limiting plate 602 for limiting and cooperating.

[0033] The fixing block 6 and the clamping member 4 are made of metal. As Figure 7 shown, the flexible belt 3 includes a flexible metal belt core 301 integrally formed with the fixing block 6 and the clamping member 4 and a flexible polymer belt sleeve 302 wrapped around the flexible metal belt core 301. The flexible belt 3 adopts the cooperation of the flexible metal belt core 301 and the flexible polymer belt sleeve 302, which can make it not easily break and have a good hand feeling. The flexible polymer belt sleeve 302 can be made of common flexible materials such as rubber and silica gel.

[0034] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
