Summary of the invention

For overcoming above-mentioned deficiency, the utility model discloses a kind of Foldable bookshelf, efficiently solve the problem that the desktop books are put required bookshelf exquisiteness, firm, collapsible, easy folding and unfolding and carried, reached ideal effect.

The technical scheme that the utility model adopted is a kind of Foldable bookshelf, comprise coaming plate, pressing plate, screw, coaming plate is established the mortise and tenon axle on one side, central layer is established the mortise and tenon rotating shaft on one side, screw fixings is in the mortise and tenon rotating shaft, and central layer can rotate, and establishes two mortise and tenons in mortise and tenon axle, the mortise and tenon rotating shaft respectively, mortise and tenon corner angle is 45 °, and the angle between two mortise and tenons is 135 °.

When the beneficial effects of the utility model are to use, only need central layer is started perpendicular to coaming plate, the mortise and tenon formula rotating shaft of two plates at this moment just in time forwards another to and puts from maintenance, and two bookshelves are relative, can place things such as books, and the discharging neat appearance is saved desk-top space.Pack up the not time spent, only need central layer is gone back to and the coaming plate flush position, become one flat plate, be easy to place or carry.The utility model design science, economical and practical, with low cost is adapted at promoting the use of in students in middle and primary schools' desk and the family's desk.
