[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-6 The utility model provides a technical solution: a new type of book cover, including a book cover body 1; in order to solve the problem that adhesive book covers are difficult to replace and card sleeve book covers have loose connections and are easy to loosen, a spine base 2 is installed on the book cover body 1, and cover book covers 3 are installed on both sides of the spine base 2. The outer sides of the cover book covers 3 are both matte-faced and made of PVC. A spine fixing mechanism 4 is provided on the spine base 2, and a book cover fixing mechanism 5 is provided on the cover book cover 3;

[0026] In order to make the book cover body 1 firmly connected to the book, the spine fixing mechanism 4 includes a spine splint 41, which is slidably installed on the spine base 2, and both ends of the spine splint 41 are installed with slide rods 42. Both ends of the spine fixing mechanism 4 are installed with slide rod sleeves 43, and the slide rod 42 is slidably installed in the slide rod sleeve 43. A downward pressure spring 44 is sleeved on the slide rod 42, and one end of the downward pressure spring 44 is installed on the slide rod 42, and the other end of the downward pressure spring 44 is installed on the slide rod sleeve 43. A slide groove 45 is provided on the spine base 2, and a movable plate 46 is installed on one side of the spine splint 41. The movable plate 46 is slidably installed in the slide groove 45. The side of the spine base 2 is opened. It is provided with a paddle slot 47, and a paddle 48 is installed on the movable plate 46. The paddle 48 is installed in the paddle slot 47. When installing a book cover on a book, select a suitable book cover body 1 according to the size of the book, and paddle 48 in the paddle slot 47 on the side of the spine base 2 is moved to make the movable plate 46 of the spine splint 41 slide in the slide groove 45 of the spine base 2, so that the two ends of the spine splint 41 drive the slide rod 42 to slide in the slide rod sleeve 43 and compress the downward pressure spring 44, so that the spine splint 41 is away from the spine base 2, and the spine of the book is placed in the spine base 2, and the paddle 48 is released. Under the action of the downward pressure spring 44, the spine splint 41 and the spine base 2 are clamped on the spine.

[0027] Example 2: Figure 3 In order to fix the cover book cover 3 and the cover, the cover fixing mechanism 5 includes a folded corner magnetic piece 51 and an anti-collision corner 52. The folded corner magnetic piece 51 and the anti-collision corner 52 are respectively installed on both sides of the cover book cover 3. The folded corner magnetic piece 51 is installed on the side of the cover book cover 3 close to the book page, and the anti-collision corner 52 is installed on the side of the cover book cover 3 away from the book page. The anti-collision corners 52 are all installed at the top corners of the cover book cover 3. The folded corner magnetic piece 51 is located on the adjacent two sides of the anti-collision corner 52. Through the adsorption effect of the folded corner magnetic piece 51 and the metal anti-collision corner 52, the cover and the cover book cover 3 at the corner of the book are adsorbed and fixed to prevent loosening. The remaining features are the same as those in Example 1.

[0028] The working principle is as follows: when installing a book cover on a book, select a suitable book cover body 1 according to the size of the book, and move the paddle 48 in the paddle slot 47 on the side of the spine base 2 to make the movable plate 46 of the spine clamp 41 slide in the slide groove 45 of the spine base 2, so that the two ends of the spine clamp 41 drive the slide rod 42 to slide in the slide rod sleeve 43 and compress the downward pressure spring 44, so that the spine clamp 41 is away from the spine base 2, and the spine of the book is placed in the spine base 2, and the paddle 48 is released. Under the action of the downward pressure spring 44, the spine clamp 41 is clamped with the spine base 2. Hold it on the spine. At this time, the cover book covers 3 on both sides of the spine base 2 are attached to the book cover. Fold the folded corner magnetic sheets 51 on both sides of the anti-collision corner 52 toward the inside of the cover. Through the adsorption effect of the folded corner magnetic sheets 51 and the metal anti-collision corner 52, the cover and the cover book cover 3 at the corner of the book are adsorbed and fixed to prevent loosening. When the book cover body 1 needs to be replaced, first fold the folded corner magnetic sheets 51 to separate the cover book cover 3 from the cover, and then move the paddle 48 in the paddle slot 47 to separate the spine splint 41 from the spine base 2, and take the spine out of the spine base 2.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
