Description

Technical Field

[0001] This utility model belongs to the field of book management shelf technology, and specifically relates to a book management shelf and a movable ladder. Background Technology

[0002] The existing book management system suffers from several problems. Many libraries fail to consider the varying heights of users and their actual needs when designing bookshelves, especially for those on higher shelves, where average readers often cannot easily reach them. This issue becomes particularly pronounced without suitable tools or equipment for retrieving books, making it exceptionally difficult for readers to find information. Secondly, there are safety concerns. Readers often need to use unstable steps or chairs to reach books on higher shelves, increasing the risk of falls and injuries and potentially affecting the stability of the bookshelves.

[0003] Conventional solutions to these problems typically involve adding movable ladders or auxiliary tools for retrieving books from the shelves. While these measures improve the convenience of book retrieval to some extent, they have drawbacks. Without proper management and training on ladder usage, improper operation by users can lead to safety hazards. Therefore, we aim to design a novel book management shelf to address this issue.
