Abstract
The utility model discloses a book placing plate having low abrasiveness on a book cover. The placing plate having low abrasiveness on the book cover comprises an elongated sheet (1), and a pulley mechanism (2) is arranged on the surrounding face of the sheet (1). The wheel diameter of the pulley mechanism (2) is slightly larger than the thickness of the sheet (1). Due to the fact that the pulley mechanism (2) is arranged on the surrounding face of the sheet (1), sliding friction between the book cover and the edges and corners is changed into rolling friction, and abrasion on the book cover in the rotating process when the book placing plate is inserted again is reduced.
Description
Technical field
The utility model relates to a kind of book position plate little to book cover abrasiveness.
Background technology
Reader enters library and obtains and first get a book position plate, in open book group, get postscript, book position plate is inserted in this book position and marks, borrow the rotation between book can keep being convenient to the interval that this book is replaced, extract book position plate out simultaneously, existing book position plate is the cuboid being cut into by sheet material, a lot of readers tend to one-handed performance and first book position plate are inserted, then get book, book position plate is inserting, the corner angle book cover that must wear and tear in rotation process, therefore, a kind of book position plate little to book cover abrasiveness is provided, and tool is of great significance.
