Bookshelf with self-adaptive height

Abstract

The invention relates to a bookshelf with self-adaptive height which comprises a bookshelf outer frame, a back plate fixedly installed on the rear portion of the bookshelf outer frame and a book containing frame arranged on the inner side of the bookshelf outer frame, an adjusting supporting outer frame plate is fixedly installed in the bookshelf outer frame on the front side of the back plate, and the book containing frame is arranged on the front portion of the adjusting supporting outer frame plate. A height self-adaptive adjusting device corresponding to the book containing frame is arranged in the adjusting supporting outer frame plate, a controller is installed on the outer side of the bookshelf outer frame, and the controller is connected with the height self-adaptive adjusting device. Movement of the book frame is limited on a plane, perpendicular to the ground, on the inner side of the bookshelf outer frame, although the motor on the rear portion occupies the horizontal space,the transverse distance of operation of the motor is greatly reduced compared with the space needed by operation of a book frame of a traditional rolling structure, and the transverse space is saved.Excessive book space does not need to be reserved at the top and the bottom of the product for operating the book frame to cross the top space, so that the advantage of saving space in the transversedirection and the longitudinal direction is achieved.

Description

technical field [0001] The invention relates to the field of libraries, in particular to a highly self-adaptive bookshelf. Background technique [0002] Bookshelves are the most widely used in libraries. Bookshelves can store and store classified and numbered books. When using traditional bookshelves, there are certain defects. These defects are concentrated in: the height of bookshelves is limited, and bookshelves cannot If it is too high, it cannot be too low. If it is too high, it will be very inconvenient for users to be limited by their height when accessing books. If it is too low, it will easily cause waste of three-dimensional space. Restricted by bookshelves of different heights, the required storage space is different. Under the premise of high space utilization, it is necessary to store as many books as possible in the same space, so bookshelves with higher loudness and height are required. This creates a paradox. Higher bookshelves can indeed store more books, b...

Problems solved by technology

However, there is a big defect in the use of this lifting bookshelf. Firstly, when lifting and lowering, the whole book frame moves vertically. All the book frames on the same horizontal plane will have all the lifting operations when the chain rotates. When the uppermost book frame is needed When accessing the books in the library, it is necessary to continuously lower the lower book frame until the upper book frame reaches a suitable position and height, and then stop the rotation of the chain to drive the operation. Then the bottom book frame may need to be rotated to the bottom of the bookshelf. The rear space position, such a setting structure not only needs to reserve a certain space at the bottom and top of the bookshelf for the rotating work space of the book frame, but also needs to reserve a thickness equivalent to a book frame at the rear of the bookshelf to implement rear pre-preparation. The rotation operation of leaving space, so that the traditional lifting bookshelf will not only take up too much three-dimensional space, but also occupy a thicker horizontal space when in use, and two traditional bookshelves that are back to back are likely to be in use. There is a phenomenon that the book frame moves to the rear and collides with each other, so the traditional lifting bookshelf lacks practicality

In addition, after the book frame of the traditional lifting bookshelf is taken out, when it is necessary to return the returned books to the initial position according to the code, because the previous user adjusted the height of the horizontal book frame, the entire book frame The order of sorting has changed a lot, and it is necessary to return to the initial position to ensure the coded storage of the book storage operation, which increases the difficulty of the return operation
