A rotating bookshelf and its manufacturing method

Abstract

The invention discloses a rotary bookshelf which comprises a central column, at least two partition plates, support plates, outer sleeves, inner sleeves and conical bearings. The rotary bookshelf is characterized in that the inner sleeves are hollow, a protruded platform is arranged at one end of each inner sleeve, and a bearing cap which is matched with the corresponding protruded platform is mounted at the other end of each inner sleeve; the hollow inner sleeves sleeve the central column and are fixed by the aid of bolts, the outer sleeves are mounted on the outer sides of the inner sleeves, and the corresponding conical bearings are respectively mounted at two ends of each outer sleeve; the partition plates are uniformly distributed and mounted on the outer side walls of the outer sleeves, and each support plate is mounted at the bottoms of the two corresponding adjacent partition plates. The rotary bookshelf has the advantages that the distances among the inner sleeves on the central column can be adjusted according to the heights of books, the outer sleeves are mounted on the outer sides of the inner sleeves, the corresponding conical bearings are respectively mounted at the upper end and the lower end of each outer sleeve, the outer sleeves are in clearance fit with the inner sleeves, and the conical bearings are in interference fit with the inner sleeves and the outer sleeves; the partition plates are uniformly distributed and mounted on the outer sides of the outer sleeves, and the support plates are mounted at the bottoms of the partition plates; users can slightly shift the partition plates, so that the books can circumferentially move around the central column; the books with the same classification numbers can be orderly placed on the rotary bookshelf.

Description

technical field [0001] The invention belongs to the technical field of bookshelves, and in particular relates to a rotating bookshelf. Background technique [0002] Most of the existing bookshelves are square, including single-sided and double-sided. The level of each layer of the bookshelf is fixed. When the books that need to be accessed are on the other side of the bookshelf, the person who accesses the books often has to walk around the bookshelf. It is inconvenient for those who access books; and there must be enough pedestrian walkways between adjacent bookshelves; especially when there are more people accessing books on holidays, conflicts often occur in the aisles between bookshelves. And the wide sidewalk occupies a large amount of study / library area, reducing the amount of books stored. Chinese patent 201120189152.2 discloses a rotating bookshelf, which is composed of a central shaft, a turntable, a partition, and a rotating sleeve; the rotating sleeve is in the s...

AI Technical Summary

Problems solved by technology

Although the patent application changes the bookshelf into a rotatable bookshelf, the height of the rotating sleeve is fixed, which is not suitable for placing books of different sizes in the same class of books; at the same time, due to the fixed structure, it cannot be adjusted according to the situation of the library. There is no separation between the layers. When there are many books in the upper bookshelf, the weight of the books will press the sleeve, which will affect the flexibility of the sleeve.
