Description

Book stand unit

Technical Field

The invention relates to the field of daily supplies, in particular to a book stand unit.

Background

The book stand is used for supporting the books to stand stably, and can prevent a row of books standing from inclining and falling down so as to prevent the books from being folded, bent or damaged. The book end can also be used for summarizing and arranging different types of books, a library mostly uses the book end to arrange a gapped bookshelf, and companies and individuals can also use the book end to open up neat book and document spaces on flat desks. In the prior art, the book end is made of materials such as iron, stainless steel and the like and is formed in pairs, a single book end generally comprises a bottom plate and a baffle plate, the bottom plate is horizontally arranged, the baffle plate is vertically arranged, the baffle plate and the bottom plate jointly form an L-shaped structure, when the book end is used, a book stands on the bottom plate and abuts against the baffle plate, and large outward acting force is applied to the baffle plate of the book end, when the books are too many, if the books abut against each other tightly, and each book is kept in an upright state, the acting force of the book on the baffle plate is small, when the books incline due to self balance, the acting force of the book on the baffle plate can force the baffle plate to move outwards, when the elastic deformation of the baffle plate per se can not bear the acting force of the book on the baffle plate, the baffle plate can drive the bottom plate to move outwards together, namely the whole book end to move, and the books can not be kept in a clamped state any more as a result of the, but can loosen and even collapse. Therefore, it is desirable to design a book stand, in which the elastic deformation between the baffle and the bottom plate is better, and the baffle can change with good adaptability to the acting force from the book, so as to maintain the clamping state of the book better and prevent the book from loosening or collapsing.
