Description

Technical Field

[0001] The utility model relates to a bookshelf, in particular to a rotating bookshelf for museum book collection. Background Art

[0002] Generally, existing bookshelves are cabinets, with books placed in layers from bottom to top. However, for books on the bottom layers, readers need to bend down or even squat when taking books; or for books on the top layers, readers may not be able to reach them when taking books; in museums, the classification and retrieval of books are very important, and the fixed structure of existing bookshelves makes it difficult to find specific books, especially in the case of a large number of books. Therefore, the industry has designed and developed a variety of rotating bookshelves, which can be rotated to any angle, making it easier to take and put books and find books, and improving the efficiency of taking and putting books and finding books. For example, the Chinese utility model patent with the authorization announcement number CN210870487U discloses a rotating bookshelf, including a base with support frames on both sides, a rotating shaft and a storage box; the rotating shaft is installed on the support frames on both sides of the base, and the two ends of the rotating shaft are welded with support rods uniformly distributed around the circumference, and the storage box is hingedly installed between the two symmetrically distributed support rods by bolts; the top and front end of the storage box are open, and a retaining bar is left at the bottom of the front end; the bolt is a bolt with a threaded head at the end, and the threaded head at the end of the bolt is threadedly connected with the nut, and the end without the threaded buckle is used as a hinged rotating shaft; the number of storage boxes is six; the rotating shaft is installed on the support frames on both sides of the base through bearings. Although this utility model patent can be rotated to any angle, making it easier to take and put books and find books; however, in actual use, when the number of books in the storage box is small, the books are more likely to become scattered due to the rotation of the storage box, which is not convenient for the arrangement of books; when the number of books in the storage box is large, the books are squeezed together and it is difficult to take out.
