Description
Technical field
The utility model relates to field of furniture, particularly a kind of liftable bookcase.
Background technology
Existing bookcase structure is fixed, and shorter people needs to require great effort very much during the books picking and placeing eminence, needs to pick and place by chair etc., easily cause tumble injury, and existing bookcase volume is comparatively large, for the study in little space, bookcase occupies a large amount of spaces usually.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of liftable bookcase, automatically can regulate the height of bookcase, when avoiding picking and placeing eminence bookcase, causes the situation of falling down, and has also greatly saved space, study simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of liftable bookcase, comprise bookcase, slide rail, motor and rotating shaft, rotating shaft is provided with thrust ball bearing, thrust ball bearing is fixed on vertical wall by fixing buckle, rotating shaft one end is provided with the second gear, second gear is connected with the first gears meshing of motor, rotating shaft is also fixed with many belts, the bottom of belt is also fixing through the trepanning on bookcase end face, bookcase is hung by belt and fits with vertical metope, bookcase and metope contact surface are provided with roller, vertical metope is provided with slide rail, slide rail is vertically arranged, roller on bookcase can slide in slide rail.
In preferred scheme, the termination that described rotating shaft is being provided with the second gear is provided with nut, and what realize the second gear is spacing and fixing.
In preferred scheme, described rotating shaft is also provided with the 3rd gear, the wall of the 3rd gear vertical direction is provided with cam, and cam can insert in the gear grooved of the 3rd gear, and cam is connected with base by the spring of vertical direction, and base is fixed on metope.
In preferred scheme, described cam is arranged with limited block, limited block is fixed on metope, and fixing point is between the fixing point and rotating shaft of base.
A kind of liftable bookcase that the utility model provides, by adopting said structure, driven by motor axis of rotation can be passed through, thus realize the folding and unfolding of belt, and then bookcase is vertically moved, the height achieving bookcase regulates, and a word pipsqueak also can be picked and placeed the books of eminence very easily, save a large amount of spaces simultaneously, other study articles for use such as desk can have been put below bookcase; Set slide rail avoids bookcase and the damage on rub for a long time between the walls bookcase and wall that cause; The cam arranged and the 3rd gear, control the rising or falling speed of bookcase, avoid the situation because velocity variations causes books to drop too soon, simultaneously when motor stalls, cam also can carry out spacing by countershaft, plays the effect of firm bookcase, ensures the stability of whole device.By adopting said structure, the height achieving bookcase regulates, and what make different height per capita can bookcase easy to use, also saves the space shared by traditional large volume bookcase simultaneously, makes space more spacious.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the 3rd gear of the present utility model and cam link position structural representation.
In figure: bookcase 1, slide rail 2, trepanning 3, the first gear 4, motor 5, nut 6, the second gear 7, thrust ball bearing 8, the 3rd gear 9, belt 10, rotating shaft 11, cam 12, limited block 13, spring 14, base 15.
Detailed description of the invention
As in figure, a kind of liftable bookcase, comprise bookcase 1, slide rail 2, motor 5 and rotating shaft 11, it is characterized in that: rotating shaft 11 is provided with thrust ball bearing 8, thrust ball bearing 8 is fixed on vertical wall by fixing buckle, rotating shaft 11 one end is provided with the second gear 7, second gear 7 is connected with a joggle with the first gear 4 of motor 5, rotating shaft 11 is also fixed with many belts 10, the bottom of belt 10 is also fixing through the trepanning 3 on bookcase 1 end face, bookcase 1 is hung by belt 10 and fits with vertical metope, bookcase 1 and metope contact surface are provided with roller, vertical metope is provided with slide rail 2, slide rail 2 is vertically arranged, roller on bookcase 1 can slide in slide rail 2.
In preferred scheme, the termination that described rotating shaft 11 is being provided with the second gear 7 is provided with nut 6, and what realize the second gear 7 is spacing and fixing.
In preferred scheme, the wall described rotating shaft 11 being also provided with the 3rd gear the 9, three gear 9 vertical direction is provided with cam 12, and cam 12 can insert in the gear grooved of the 3rd gear 9, cam 12 is connected with base 15 by the spring 14 of vertical direction, and base 15 is fixed on metope.By cam and the 3rd gear, avoid bookcase to shake because the rotation speed change of rotating shaft is excessive, also can carry out spacing by countershaft simultaneously, fixation is played to whole device.
In preferred scheme, described cam 12 is arranged with limited block 13, and limited block 13 is fixed on metope, and fixing point is between the fixing point and rotating shaft 11 of base 15.Set limited block 13, effectively prevent the cam caused because of camber of spring crooked, the situation that cannot normally work occurs.
By adopting said structure, the height achieving bookcase regulates, and what make different height per capita can bookcase easy to use, also saves the space shared by traditional large volume bookcase simultaneously, makes space more spacious.
