The bookcase body 1 in the embodiment of the invention is a row of cabinet body units of a bookcase. The bookcase provided by the embodiment of the invention further comprises a lifting device, a push-pull device and book lattices 5, wherein the size of the book lattices 5 is matched with that of the book placing layer. When the book shelf is used, the book shelf 5 is pushed out or pulled back to the book placing layer by the push-pull device, and the lifting device drives the book shelf 5 to move up and down.

The book cabinet with the automatically liftable interlayer has the advantages that the book grids 5 are arranged in the book placing layer on the high layer, the book grids 5 are used for placing books, the push-pull device can push the book grids 5 out of the book placing layer or pull the book grids back into the book placing layer, and the lifting device can lift the book grids 5. When a book needs to be taken from the high-level book placing layer or placed in the high-level book placing layer, the book lattices 5 in the book placing layer are horizontally pushed out of the book placing layer through the push-pull device, the book lattices 5 are lowered to the height which can be taken by a user through the lifting device, after the book is taken and placed, the book lattices 5 are lifted to the original book placing layer through the lifting device, and the book lattices 5 are pulled back into the book placing layer through the push-pull device. The bookcase provided by the embodiment of the invention avoids potential risks of climbing up and down when books are stored and searched in the traditional cabinet type bookcase, and improves the use safety. The height of the bookcase is limited by the height of the user, so that the user can conveniently and easily select and take high-rise books.

In the embodiment of the invention, when a high-level book-placing layer is required to take and place books, the lifting device can be pulled out, and after the lifting device is used, the lifting device can be retracted to be tightly attached to the cabinet body 1 of the bookcase, so that the space is saved.

Preferably, the push-pull device comprises a telescopic piece and a hook 12 with a downward opening, wherein the telescopic piece is fixed on the partition plate 6 positioned below the book placing layer. The telescopic part is connected with the hook 12 and is used for driving the hook 12 to move along the depth direction of the book placing layer. The book grid 5 is provided with a buckle 17 matched with the hook 12. When a book needs to be taken or put, the book lattices 5 are positioned in the book placing layer, the clamping hooks 12 are clamped with the clamping buckles 17, and the telescopic pieces drive the clamping hooks 12 to move towards the outer side of the bookcase body 1, so that the book lattices 5 are pushed to move outwards until the book lattices 5 are positioned on the tray 3. The tray 3 moves downwards, so that the buckle 17 automatically disengages from the hook 12 with the downward opening, and the book grid 5 descends under the driving of the lifting device. After the book is taken or put, the lifting device drives the book lattices 5 to ascend to the outer side of the corresponding book placing layer, at the moment, the clamping hooks 12 automatically hook the buckles 17, and the telescopic pieces drive the clamping hooks 12 to move towards the inside of the bookcase body 1, so that the book lattices are pulled to move inwards until being positioned in the book placing layer.

Further, as shown in fig. 2, the telescopic part comprises a steering engine 11, a crank 15, a connecting rod 10 and a sliding block 14, the steering engine 11 is fixed on the partition plate 6, the steering engine 11 is connected with one end of the crank 15, the other end of the crank 15 is rotatably connected with one end of the connecting rod 10, the other end of the connecting rod 10 is rotatably connected with a hook 12, and the hook 12 is fixedly connected with the sliding block 14. The partition board 6 is provided with a slide rail 13 along the depth direction of the book placing layer, and the slide block 14 is connected with the slide rail 13 in a sliding way.

Preferably, the book lattices 5 are M and are respectively positioned in M continuous book placing layers from top to bottom of the bookcase body 1, and M represents an integer larger than or equal to N. Book grids 5 are arranged in the high-rise M book placing layers of the bookcase body 1, so that the bookcase is convenient for taking and placing books on the high-rise. The middle and lower layers are within the height range of most users, and the book grid 5 is not needed.

Furthermore, push-pull devices are arranged in M continuous book placing layers from top to bottom. The book placing layers with the book lattices 5 are all provided with push-pull devices, and the push-pull devices correspond to the book lattices 5 one by one. If only one push-pull device is adopted, the push-pull device needs to be lifted synchronously with the tray. In the embodiment of the invention, each book lattice 5 corresponds to one push-pull device, and compared with the mode that one push-pull device is shared, the book lattice has the advantages of simple structure, convenience in control and stable and reliable work.

The use method of the bookcase with the automatically liftable interlayers in the preferred embodiment is as follows:

when a book needs to be taken or put, the lifting device is pulled outwards to a proper position, and after a starting key of a specified book placing layer is pressed, the lifting device is positioned at an initial position, namely the tray 3 in front of the top end of the bookcase is lowered to a position which is parallel to the specified book placing layer along with the rotation of the screw rod 4. The book compartments 5 are then moved horizontally outward onto the tray 3 under the urging of the urging means, as shown in fig. 5. The stepping motor 22 drives the screw rod 4 to rotate, so that the tray 3 with the book grids 5 descends to a designated position and stops automatically. After taking or putting books, the start key on the layer is pressed again, the stepping motor 22 drives the screw rod 4 to rotate reversely, so that the tray 3 drives the book grids 5 to ascend to the original height, the push-pull device pulls the book grids 5 back to the book putting layer, then the tray 3 ascends to the initial position, and one-time lifting taking and putting are completed. When not in use, the lifting device is retracted to be close to the bookcase body 1.
