[0012] 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 protection scope of the present utility model.

[0013] like Figure 1-8As shown, this utility model provides a technical solution: a book cover that prevents detachment, including a spine plastic board 1, with a front cover plastic board 2 and a bottom cover plastic board 3 respectively provided on both sides of the spine plastic board 1. Soft plastic strips 4 are fixedly connected to both sides of the spine plastic board 1, and the sides of the two soft plastic strips 4 are fixedly connected to the sides of the front cover plastic board 2 and the bottom cover plastic board 3 respectively. The soft plastic strips 4 allow the front cover plastic board 2 and the bottom cover plastic board 3 to be folded relative to the spine plastic board, so that the front and bottom covers of the book 11 are protected while allowing for normal page turning. A cover sleeve 5 is fixedly provided on the top surface of the outer side of the front cover plastic board 2 and the bottom cover plastic board 3. The side of the cover sleeve 5 has an opening. Two soft plastic strips 4 are fixedly connected to the top surface of the front cover plastic board 2 and the bottom cover plastic board 3 respectively. The clamping plate 6, by its design, positions the telescopic rigid plastic plate 9 after it has extended and rotated horizontally within the swing support rigid plastic plate 8. This prevents the telescopic rigid plastic plate 9 and the swing support rigid plastic plate 8 from rotating to other angles that would prevent them from limiting and supporting the front and bottom covers of the book 11. The inner wall of the groove of the clamping plate 6 is provided with a locking block 10, which secures the telescopic rigid plastic plate 9 within the groove on the back of the clamping plate 6, preventing it from rotating or swinging. The four clamping plates 6 are symmetrically distributed around the center of the spine plastic plate 1, with the book 11 placed on top of the spine plastic plate 1. The top surface of the spine plastic plate 1 is in contact with the back of the spine of the book 11. Both the front and back covers are in an unfolded state, with the top surface of the front cover plastic plate 2 in contact with the front cover of the book 11, and the top surface of the back cover plastic plate 3 in contact with the back cover of the book 11. One side of the front cover of the book 11 is inserted into the left cover sleeve 5, and one side of the back cover of the book 11 is inserted into the right cover sleeve 5. The cover sleeves 5, by inserting the front and back covers of the book 11 into the cover sleeves 5 on both sides, effectively position the front and back covers of the book 11, ensuring continuous protection for the front and back covers of the book 11. Two shaft pieces 7 are fixedly mounted on the top surface of the cover sleeve 5, symmetrically distributed around the center of the cover sleeve 5. A swing support hard plastic plate 8 is rotatably sleeved on the surface of the shaft piece 7. A telescopic hard plastic plate 9 is slidably inserted into the side of the swing support hard plastic plate 8. A slope is provided on one side of the top surface of the telescopic hard plastic plate 9. One end of the telescopic hard plastic plate 9 passes through the through groove provided on the bottom surface of the clamping piece 6. Through the setting of the telescopic hard plastic plate 9 and the swing support hard plastic plate 8, the telescopic hard plastic plate 9 can be extended and lengthened inside the swing support hard plastic plate 8, and rotated synchronously to a horizontal state. The combination of the swing support hard plastic plate 8 and the telescopic hard plastic plate 9 supports the outside of the front cover and back cover of the book 11, which greatly increases the folding range of the front cover and back cover of the book 11 when pulled out of the cover 5, and improves the stability of the fit between the front cover and back cover of the book 11 and the front cover plastic plate 2 and the back cover plastic plate 3.

[0014] In use, place the spine of the book 11 against the top surface of the spine plastic board 1, then turn the pages of the book 11 one by one to open the front and back covers, and insert them into the corresponding side covers 5. Then pull the corresponding telescopic hard plastic board 9 outwards while rotating the swing support hard plastic board 8 to a horizontal position. Push the telescopic hard plastic board 9 into the slot on the back of the clamping piece 6, so that the telescopic hard plastic board 9 is horizontal and passes through the slot on the back of the corresponding clamping piece 6, and is then locked inside by the locking block 10. At this point, the book can be opened. When the front and back covers of book 11 are folded and closed, the outer surfaces of the front and back covers of book 11 are completely covered by the front cover plastic plate 2 and the back cover plastic plate 3. The rigid plastic plate 8 and the telescopic rigid plastic plate 9 are used to support the outer surfaces of the front and back covers of book 11, which greatly increases the folding range of the front and back covers of book 11 when they are pulled out from the cover 5. This effectively prevents the front and back covers of book 11 from easily detaching from the protective plastic cover. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0015] In summary, this anti-fall-off book cover works by inserting the front and back covers of the book 11 into the cover sleeves 5 on both sides, then rotating the rigid plastic support plate 8 to a horizontal position, and coordinating with the telescopic rigid plastic plate 9 to extend and retract within the rigid plastic support plate 8. This allows the telescopic rigid plastic plate 9 to pass through the groove on the back of the corresponding clamping piece 6. The fit between the rigid plastic support plate 8 and the telescopic rigid plastic plate 9 supports the front and back covers of the book 11 on the outside, greatly increasing the folding range of the front and back covers when pulled out of the cover sleeve 5. This effectively prevents the front and back covers of the book 11 from easily falling out of the cover sleeve 5 and affecting the protection of the book.
