CN203709549U - Portable compactible bookshelf - Google Patents

Abstract

The utility model discloses a portable compactible bookshelf which is a foldable and conveniently carried bookshelf and is characterized in that four slots are formed in each of the left and right sides of a bookshelf base, two brackets hinged to a panel are arranged at the rear part of the oblique panel, the tilt degree of the oblique panel of the bookshelf can be changed by inserting the two rotatable brackets into the different slots in the base, and the angle of the bookshelf can be adjusted by readers according to the habits. When books are put on an upper panel of the bookshelf, the lower parts of the books are compacted by a compaction rod according to a lever principle under the action of gravity of the books; the upper parts of the books can be pressed through two elastic pressure plates capable of sliding up and down, so that users do not need to press the books by the hands at any time during reading; as the books have different sizes, the two elastic pressure plates capable of sliding up and down relative to the oblique panel are designed and pushed to a proper position according to the sizes of the books.
