[0004] In addition, in the prior art, such as a bookshelf with publication number CN204427198U, a bookshelf body is divided into several unit storage areas for placing books by arranging horizontal partitions and vertical partitions. Three book stops are provided in each unit storage area to prevent the books from tilting. Small baffles are provided between the book stops to further prevent the books from tilting. Arc-shaped notches are provided on the book stops to facilitate borrowers to access books. Horizontal baffles are provided to prevent books from falling from the rear end of the bookshelf when taking or storing books. The utility model has a simple structure, is convenient and practical, and the books will not tilt when placed, and are easy to organize and access. Barcodes corresponding to the books are provided on the horizontal partitions, which also facilitates borrowers or administrators to put books in the correct position. It is convenient and practical, but its structure is fixed and cannot be adjusted accordingly according to the size of the books and the placement requirements, which reduces the practicality of the bookshelf.

[0005] In addition, in the prior art, there is a bookshelf with a publication number of CN215347679U, which allows books to be placed into the storage cavity through a take-out opening, and the layers are used to support the books, thereby storing the books. The overall space occupied is small, and the stored books can be easily observed through the mesh panel, making it more convenient to take and put the books, and more convenient to use. The books are placed into the storage cavity through the take-out opening, and the layers are used to support the books, thereby storing the books. The overall volume of the bookshelf is not large, and the space occupied is small. When the books need to be transported, the bookshelf can be moved and can be directly pushed for transportation, making it more convenient to carry the books. In addition, the stored books can be easily observed through the mesh panel, making it more convenient to find and take out the books to be taken out. However, its movable structure is a universal wheel structure, lacking a fixed support structure, which easily causes the position of the bookshelf to shift in actual use, and there are certain usage defects.
