A driving wheel is arranged at each of the top and the bottom of the inner face of each side wall, a wire rope is wound on every two corresponding driving wheels in a circle, each book holder is hung on a cross shaft through a steel rod, each cross shaft is hinged to the wire ropes, protrusions are arranged at two ends of each cross shaft and matched with corresponding guide rail grooves in the inner faces of the side walls, a control mechanism is arranged on each lower driving wheel, each control mechanism comprises a driving motor, a coupling and a self-locking worm reducer, each self-locking worm reducer and the corresponding driving wheel share a same power shaft, a spring is arranged on the side wall of one inner end of each book holder, and a retaining plate is arranged at the free end of each spring. By the rotary lifting book shelf, each layer of the book shelf can be rotated to the appropriate height, and the requirement on double-sided use is met.

Description

technical field [0001] The invention relates to a book shelf, in particular to a rotating and lifting book shelf. Background technique [0002] The bookshelf is a widely used tool for storing books in universities and libraries. The usage rate is very high. In order to save space and put more books, the usual book shelves are relatively high, and the books placed in high places are not It is convenient to check and take, and the books placed in the lower place also need to bend down to look up, causing a lot of trouble to the user. [0003] The existing lifting bookshelves usually move the upper part of the bookshelf down from the front of the bookshelf as a whole, so as to facilitate the reading of high books. This kind of bookshelf will inevitably produce two disadvantages. One is that the lower bookshelf cannot be used normally, and the other is that The bookshelf can only be set on one side instead of two sides, which greatly reduces the use efficiency of the bookshelf ...

[0003] The existing lifting bookshelves usually move the upper part of the bookshelf down from the front of the bookshelf as a whole, so as to facilitate the reading of high books. This kind of bookshelf will inevitably produce two disadvantages. One is that the lower bookshelf cannot be used normally, and the other is that The bookshelf can only be set on one side instead of two sides, which greatly reduces the efficiency of the bookshelf and is still not convenient enough to use
