The distance of line to 30 bottom of bookshelf is L12, and L11Less than L12.Meanwhile 35 axis of rear support axis to the top of bookshelf 30 away from
From for L21, the distance of 35 axis of rear support axis to 30 bottom of bookshelf is L22, and L21Less than L22, and on same bookshelf 30
The axis of front support axis 31 and rear support axis 35 overlaps.The structure can make bookshelf 30 be predominantly located in front support axis 31 and after
The axis of support shaft 35, can be real under the effect of gravity hereinafter, bookshelf 30 is made whether to be loaded with books or unloaded books
It now makes heart function (no matter how i.e. preceding turntable 61 and rear turntable 62 rotate, the bottom surface of bookshelf 30 is parallel in ground always) by oneself, prevents
Only bookshelf 30 is turned on one's side caused by loading books excessively.
Because bookshelf 30 is open-topped structure, both sides imperforation, so books are after bookshelf 30 is loaded into, Bu Huicong
30 both sides of bookshelf are fallen.
As preferred structure, L11With L12The ratio between can be 1:4, L21With L22The ratio between also be 1:4.In this way, just it is enough to ensure that book
The center of gravity of frame 30 is always under axis.
With reference to shown in figure 5, Fig. 6 and Fig. 7, on the two sides of bookshelf 30, it is both provided with card slot 33.30 both sides of bookshelf point
It is not fixedly connected with a snap-gauge 32, bar hole 38 is respectively provided on each snap-gauge 32;At least one bar 34 is located at card slot 33 and works as

There is compression spring 44, compression spring 44 is between carrier 42 and Universal castor 45.The structure can be compressed compression spring 44, i.e.,:Work as dress
When the books of load are appropriate, compression spring 44 is reduced but is not zero with ground distance by moderate compression, the at this time side of L-type support frame 41,
Then L-type support frame 41 is not just contacted with ground, and universal wheel can be rolled normally.When the books of loading are excessive, compression spring 44 is by mistake
Degree compression, then the side of L-type support frame 41 and ground distance are zero, and L-type support frame 41 is directly contacted with ground.At this point, moving
In dynamic process, this book carrier, book conveyor can send out harsh noise, librarian's books be prompted to load excessive.Again because L-type supports
Frame 41 forms the rolling friction of the non-universal wheel of sliding friction after directly being contacted with ground, so this mobile book carrier, book conveyor can extremely be eaten
Power can equally play the role of prompting librarian's books overladen.
In this way, it is possible to ensure this book carrier, book conveyor during use, universal wheel premature breakdown will not be caused due to overload
.
In order to facilitate use, the present invention is also equipped with handrail 50 on rear bearing sheet 23.
In use, books to be given back are loaded into bookshelf 30, then take the circumstances into consideration to be fixed or separated with bar 34.Figure
After book administrator pushes this book carrier, book conveyor to corresponding large-scale bookshelf, the books in the bookshelf of the top are not bent over to take out, are directly put
Enter in large-scale bookshelf.Then, this book carrier, book conveyor is pushed then to press the motor on front end panel 21 to next large-scale bookshelf
Switch 101, then turntable 61 rotates before motor 10 drives, and next bookshelf 30 is made to take turns the position for going to previous bookshelf.Unclamp electricity
Machine switch 101, motor 10 can be by preceding 61 locking of turntable.Because each bookshelf 30 is respectively provided with Self-centering Action, then can realize
Preceding turntable 61 and rear turntable 62 when being revolved round the sun clockwise, bookshelf 30 can automatically carry out constant angular velocity counterclockwise from
Turn, and then ensure that all bookshelves 30 are in horizontality always.After the completion of rotation, underlying 30 height of bookshelf carries originally
It rises, then librarian can not bend over directly that book is taken to give back from the bookshelf 30 after rotation, very convenient.Because there is motor 10
Automatic locking acts on, so during also book, even if 3 bookshelves 30 in left side fill books, 3 bookshelves 30 on right side
Also book completes (vacant), and 3 bookshelves 30 in left side will not counterclockwise be rotated because of the effect of gravity, Jin Erbao
The bookshelf 30 for having demonstrate,proved books to be given back is in highest order always so that no matter librarian gives back the books of which bookshelf 30,
It need not bend over to take book.
