And lower body, it is connected between upper plate body and lower body by hinge hinge, further includes the hoistable platform positioned at 1 upper end of moving trolley
12, the lower end of hoistable platform 12 is connect by electric pushrod with the upper end of moving trolley 1, and handle is additionally provided in moving trolley 1, and
The lower end of moving trolley 1 is additionally provided with mobile universal wheel, is the conventional arrangement means of the prior art, does not do excessive elaboration herein.
Working principle: in the use of the present invention, being first placed into books in the placement space of book bucket 3, user passes through again
Push the handle of moving trolley 1 so that moving trolley 1 is moved to and needs position, at this point, user is to the books in placement space
Carry out work of taking；
Specifically, the books of its bottom surface are to be not easy to take at this time after the books of placement space upper end are taken
, user starts any servo motor and rotates forward, and servo motor rotates forward so that wirerope I 7 is wrapped in third ring
In shape slot, or it is wrapped in wirerope II 8 in fourth annular slot；
In the above-described embodiments, when wirerope I 7 is wrapped in third annular groove, the book bucket 3 of top in bookshelf 2 is driven
The cylinder 4 in outside, so that the cylinder 4 moves up in the first slideway, so that the bending part of the book bucket 3 forms upward lift
Dynamic, the first supporting plate 5, the second supporting plate 6 of the book bucket 3 shorten at this time, so that the horizontal spacing of the placement space of the book bucket 3 becomes larger,
It takes convenient for user to the books in book bucket, when wirerope II 8 is wrapped in fourth annular slot, drives in bookshelf 2
The cylinder 4 in 3 outside of book bucket of lower section, so that the cylinder 4 moves up in the first slideway, so that the bending part shape of the book bucket 3
It is lifted at upward, the first supporting plate 5, the second supporting plate 6 of the book bucket 3 shorten at this time, so that the transverse direction of the placement space of the book bucket 3
Spacing becomes larger, and equally takes convenient for user to the books in book bucket 3；
It should be noted that forming one to the inside of book bucket 3 after books are placed into the placement space of book bucket 3
Determine the tension of degree, the inside of book bucket 3 is easy to receive tension and open, so that servo motor drives cylinder 4 in the first slideway
Move up more efficiently and conveniently；
Require supplementation with herein when, when cylinder 4 moves up and down in the first slideway, at the fixture block 10 of straight-bar 9 and its end
In discrete state (as shown in Figure 9), i.e. telescopic rod is in the first slideway, and fixture block 10 is to be on the outside of the first slideway, and
Cylinder 4 after movement, fixture block 10 is inserted into matched card slot, so that the position of the first supporting plate 5,6 upper end of the second supporting plate
Fixation is set, the weight of book bucket 3 is effectively carried, and the gravity of 3 bending part of book bucket is carried by servo motor；
In the present embodiment, when needing books being placed into eminence, books are placed on hoistable platform 12, by electronic
Books are transported to eminence by push rod, furthermore, it is desirable to servo motor is rotated backward when expanding the volume of placement space, i.e. steel wire
Restrict I 7 upper end to cylinder 4 is mobile or the upper end of wirerope II 8 is mobile to cylinder 4, relieve wirerope I 7 or wirerope at this time
The support force of II 8 pairs of book buckets 3, book bucket 3 move down under gravity, so that cylinder 4 moves down in the first slideway,
First supporting plate 5, the elongation of the second supporting plate 6, so that the side wall length of book bucket 3 is extended, depth is also extended, to expand
The volume of placement space can accommodate more books；
The present invention folds (as shown in Figure 4) when not in use, by book bucket 3, and cylinder 4 is separated with book bucket 3, can be by book bucket
3 remove from bookshelf 2, then transmission shaft II, transmission shaft III are separated with the output end of servo motor respectively, can be by 2 folding of bookshelf
It is folded, it is formed shown in Fig. 2, largely reduces the occupied space of structure, herein preferably, cylinder 4 and book bucket 3, Yi Jichuan
Moving axis II, transmission shaft III respectively with the output end of servo motor, it is above-mentioned may each be by screw thread realize connection with separate,
It can be the connection type of any other detachable structure composition, this will not be repeated here；
Certainly, the book bucket 3 in the present embodiment, storage and placing appliance not only as books, additionally it is possible to as book
The displaying apparatus of nationality, the side cross-sectional of book bucket 3 are V-arrangement, books can be overlapped along the inside edge of book bucket 3 and be placed, at this point, book
Be bonded on the inside of the back side of nationality and book bucket 3 its formed along book bucket 3 it is skewed so that the front of books is oblique in face of the outer of book bucket 3
Side forms and shows well.
Only presently preferred embodiments of the present invention is not intended to limit the invention, all in the spirit and principles in the present invention
Within made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention.
