Description

Bookshelf capable of moving back and forth for library

Technical Field

The invention relates to the field of education auxiliary facilities, in particular to a bookshelf capable of moving forwards and backwards for a library.

Background

Education plays a crucial role in the development of each country, wherein the main way of reading is taken, and in order to facilitate reading by the public, each country will set up libraries in different institutions or units to collect, arrange and collect book materials for people to read and refer. The only equipment for storing books in the library is a bookshelf, and various books are placed on the bookshelf. The existing bookshelves generally comprise shelf bodies and partition plates, the partition plates are distributed along the height direction of the shelf bodies, each bookshelf is transversely or longitudinally arranged indoors to form a library, and books borrowed by people are placed to the original positions again through pushing the trolleys in daily activities of book management personnel, so that other people can find the books conveniently. However, due to the long-distance arrangement of the plurality of bookshelves in the library, the route for the manager to push the trolley to place the books for walking is long, and the manager often sees that the manager pushes the trolley to bypass around the bookshelves, which undoubtedly brings inconvenience to the management work of the books and makes the workload of the manager complicated. Although the prior art also has bookshelves which can be moved or moved, the stability of the bookshelves is reduced due to the mobility of the bookshelves, and the invention provides the bookshelves which can be moved and have the stability.
