A kind of rotatable bookshelf
Technical field
The present invention relates to a kind of bookshelf, is especially a kind of rotatable bookshelf.
Background technology
Bookshelf in existing library is mostly rectangle, is generally three to four layers, is furnished with multiple grid for putting similar books in every layer.Bookshelf mostly is fixed, and reader normally habitually reads the reading matter in two or three layers that conveniently consult, and needs to need to look for keeper to help when checking the reading matter in four layers or more high-rise and gets book when having or need to look for the instruments such as stool to get on to get; And have to when readers' needs checks the reading matter of lowermost layer bend to consult, so not only expend muscle power but also enjoyment or the energy of readers ' reading can be had influence on.
Summary of the invention
In order to overcome above-mentioned defect, the present invention proposes a kind of rotatable bookshelf, it makes reader when consulting the books of eminence or lower, only need press corresponding motor switch and just can control corresponding sleeve and interior books turn to suitable position, solve inconvenience when reader consults books to a great extent.
The technical solution used in the present invention is as follows:
A kind of rotatable bookshelf, comprises T font support, book frame portions and multiple Power Component.
Each described book frame portions comprises four sleeves, be followed successively by the first sleeve from outside to inside, second sleeve, 3rd sleeve and the 4th sleeve, described four sleeves are concentric, the home position place of described four sleeves is provided with back shaft, described back shaft is fixed on T font support, for supporting whole book frame portions, described four sleeves and described back shaft are so configured to each sleeve can be rotated when not affecting contiguous sleeve or back shaft relatively independently, described first sleeve, second sleeve, the axial length of the 3rd sleeve and the 4th sleeve increases successively, and the outer face of described four sleeves flushes, inner face is stepped-style, each described sleeve outside end is provided with multiple grid, for putting books, and be provided with on this inner face for the lid for reader's manual unlocking and closedown.
The quantity of described Power Component is eight, for driving each sleeve of each described book frame portions respectively, each Power Component comprises motor, screw rod, screw shell, jointed shaft and Y type fork bar, rotate for driving corresponding sleeve, wherein the described motor of eight described Power Components is disposed side by side on left and right two horizon bar of T font support respectively, for driving corresponding bolt rotary; Described screw rod and screw shell threaded engagement, described jointed shaft is fixedly installed on described screw shell, the two opposite sides bar of described Y type fork bar is hinged with the two ends of described jointed shaft respectively, and the lower end of the vertical bar of described Y type fork bar is hinged on the inner face place of relevant sleeve.
When motor rotates forward, drive screw turns, thus drive screw shell to move down, and then drive Y type fork bar to move down by jointed shaft, thus corresponding sleeve is rotated, when being positioned at the books above bookshelf body and turning to the position of expectation, control motor stalls by motor switch; When motor reversal, drive screw turns, thus drive screw shell to move up, and then drive Y type fork bar to move up by jointed shaft, thus corresponding sleeve is rotated, when being positioned at the books below bookshelf body and turning to the position of expectation, control motor stalls by motor switch.
Wherein, bearing is provided with between sleeve and back shaft and between each sleeve.
By arrange multiple can the concentric sleeve of relatively independent slip and corresponding Power Component, can make multiple reader, on not interactional basis, the books of eminence or lower be turned to the position of oneself conveniently consulting; By being the corresponding motor of each ferrule configuration and other Power Components, the automatic rotation of sleeve and interior books thereof can be realized; By arranging four Power Components be arranged symmetrically with, make the Power Component on same T font support that two book frame portions can be driven to rotate.

Fig. 2 is the left view of Fig. 1, simply show inner side bookshelf by schematic diagram during power Component driver.
Detailed description of the invention
With reference to Fig. 1-2, a kind of rotatable bookshelf, comprise T font support 9, book frame portions and multiple Power Component, the quantity of described book frame portions is two, is separately positioned on left and right two horizon bar of described T font support 9,
Each described book frame portions comprises four sleeves, be followed successively by the first sleeve 1 from outside to inside, second sleeve 2, 3rd sleeve 3 and the 4th sleeve 4, described four sleeves are concentric, the home position place of described four sleeves is provided with back shaft 11, described back shaft 11 is fixed on T font support 9, for supporting whole book frame portions, described four sleeves and described back shaft 11 are so configured to each sleeve can be rotated when not affecting contiguous sleeve or back shaft 11 relatively independently, described first sleeve 1, second sleeve 2, the axial length of the 3rd sleeve 3 and the 4th sleeve 4 increases successively, and the outer face of described four sleeves flushes, inner face is stepped-style, each described sleeve outside end is provided with in multiple grid 5(Fig. 1 not shown), for putting books, and be provided with on this inner face for the lid for reader's manual unlocking and closedown.
The quantity of described Power Component is eight, for driving each sleeve of each described book frame portions respectively, each Power Component comprises motor 8, screw rod 12, screw shell 6, jointed shaft 13 and Y type fork bar 7, rotate for driving corresponding sleeve, wherein the described motor of eight described Power Components is disposed side by side on left and right two horizon bar of T font support 9 respectively, rotates for driving corresponding screw rod 12; Described screw rod 12 and screw shell 6 threaded engagement, described jointed shaft 13 is fixedly installed on described screw shell 6, the two opposite sides bar of described Y type fork bar 7 is hinged with the two ends of described jointed shaft 13 respectively, and the lower end of the vertical bar of described Y type fork bar 7 is hinged on the inner face place of relevant sleeve.
When motor 8 rotates forward, drive screw 12 rotates, thus drive screw shell 6 to move down, and then drive Y type fork bar 7 to move down by jointed shaft 13, thus corresponding sleeve is rotated, when being positioned at the books above bookshelf body and turning to the position of expectation, control motor 8 by motor switch and stop operating; When motor 8 reverses, drive screw 12 rotates, thus drive screw shell 6 to move up, and then drive Y type fork bar 7 to move up by jointed shaft 13, thus corresponding sleeve is rotated, when being positioned at the books below bookshelf body and turning to the position of expectation, control motor 8 by motor switch and stop operating.Valuably, wherein, bearing (not shown) is provided with between sleeve and back shaft and between each sleeve.
