Multilayer turnover plate type book car
Technical field
The utility model relates to the books equipment technical field, is a kind of multilayer turnover plate type book car specifically.
Background technology
At present, the library is used for binding in enormous quantities upper and lower of books and periodicals and stack room adjustment falls the book car of frame and is generally multilayer book car, and the book supporting board of each layer of book car is fixed on the support of book car.When staff's dress book or when book supporting board was got book, except that top layer, all the other each layers all were subjected to stopping of upper strata book supporting board, must avoid the upper strata book supporting board, could adorn book or get book on lower floor's book supporting board on the book car book supporting board.Fixedly installing of each layer book supporting board, make the staff on middle each layer of book car and bottom book supporting board, adorn, the speed of getting book is all lower than the top layer, hold time that Book of Records goes through and path also than the length of top layer, inefficiency not only, and labour intensity is big, particularly when the book car is between two less row's bookshelves of array pitch, staff's action radius is dwindled, dress, getting the book action is restricted, the barrier effect of upper strata book supporting board is more obvious, and under the stopping of upper strata book supporting board, can not see the literal on the books spine on lower floor's book supporting board clearly from the front, this makes work efficiency and labour intensity further develop to unfavorable direction.
Summary of the invention
The purpose of this utility model provides a kind of multilayer turnover plate type book car, this book car is except that the bottom book supporting board is fixing, all the other each layer book supporting boards are all turning, make the staff at dress on book car lower floor book supporting board, when getting book, as long as overturn the upper strata book supporting board up or down, just can not be subjected to the influence of upper strata book supporting board, thereby improve the efficient of upper and lower of books in enormous quantities and reduce staff's labour intensity.
For achieving the above object, the technical scheme that the utility model is taked is, except that the bottom book supporting board, each links to each other with the column of book kickstand with a hinge all the other each layer book supporting boards at the two ends on an one long limit, make book supporting board upwards overturn 90 ° to the plumb position from level attitude around hinge, also can overturn 90 ° downwards from the plumb position to level attitude around hinge, promptly rotational angle is between 0 ° to 90 °, as shown in Figure 2.The utility model is made of support, universal wheel, book supporting board, hinge and magnetic, and wherein, support constitutes by column and with cooresponding cross-tie of each layer book supporting board and longitudinal ligament.Each layer of book car has 2 cross-ties, is arranged in the and arranged on left and right sides of book car, and the while is as the bearing of book supporting board.Book car bottom has 2 longitudinal ligaments, is arranged in the forward and backward both sides of book car, and is fixed together with the bottom book supporting board; Top layer and interlayer respectively have 1 longitudinal ligament, are arranged in book car rear side.Each layer longitudinal ligament is identical apart from ground-surface height with the equivalent layer book supporting board apart from ground-surface height.
The beneficial effects of the utility model are: because except that bottom, the book supporting board of all the other each layers transform as convertible by fixed type, therefore, at dress on book car lower floor book supporting board, when getting book, each layer book supporting board is all turning on it.After the book supporting board upset of upper strata, lower floor becomes top layer, not only can look at the literal on the books spine from the front straight, and book is adorned, got in path that can be the shortest directly toward lower floor, and be not subjected to the influence of upper strata book supporting board, thereby shortened the staff and adorned, getting the time and the path of holding book in the book process, dress, get the book process and become convenient and swift, improve work efficiency effectively and reduced labour intensity, particularly when the book car is between two less row's bookshelves of array pitch, this effect will show more obviously.

Among the figure: the universal wheel of 1-; The 21-column; The 22-cross-tie; 231-bottom longitudinal ligament; 232-top layer or interlayer longitudinal ligament; 31-bottom book supporting board; 32-top layer or interlayer book supporting board; The 4-hinge; The 5-magnetic.
The specific embodiment
A kind of multilayer turnover plate type book car is shown in Fig. 1-4.Comprise support, universal wheel 1 and book supporting board, support constitutes by column 21 and with cooresponding cross-tie 22 of each layer book supporting board and longitudinal ligament.Except that bottom book supporting board 31, each links to each other with bracket upright post 21 with a hinge 4 all the other each layer book supporting boards 32 at the two ends on an one long limit, the cross-tie 22 of support is as the bearing of book supporting board 32, magnetic 5 is set on the column above the hinge 4 21, and the distance between hinge 4 and the magnetic 5 equals book supporting board 32 width.Except that bottom book supporting board 31, all the other each layer book supporting boards 32 all can rotate around hinge 4, and slewing area is between cross-tie 22 and magnetic 5, promptly between 0 ° to 90 °, as shown in Figure 2.Each layer has 2 cross-ties 22, arranges that along 2 minor faces of book supporting board promptly be arranged in the and arranged on left and right sides of book car, the while is as the bearing of equivalent layer book supporting board, as shown in Figure 1 respectively.Each layer longitudinal ligament is identical apart from the ground-surface height of ground-surface height and equivalent layer book supporting board distance, promptly with the equivalent layer book supporting board in same horizontal surface.Bottom longitudinal ligament 231 has 2, is arranged in the forward and backward side of book car, abut against with two long limits of bottom book supporting board 31, and captive joint, as shown in Figure 3; Top layer and interlayer, every layer of 1 longitudinal ligament 232 is arranged in the rear side of book car, a side of hinge promptly arranged, as shown in Figure 4 on the book supporting board.
Described column 21, longitudinal ligament and cross-tie 22 all adopt the metal square pipe, constitute support by welding, each layer book supporting board adopts the thick ferrimagnetism sheet material of 0.8-1.0mm, for improving its load-carrying capacity, its shape of cross section as shown in Figure 2, described hinge adopts the form of hinge, and two metals of hinge weld with bracket upright post and book supporting board respectively, and hinge length is not more than the bracket upright post width.
Before dress book on the book car, at first the entrucking of the good books and periodicals of adorning of planning in proper order, then each layer book supporting board upwards overturn 90 °, it is adsorbed on the cooresponding magnetic, begins to adorn book, install one deck from lower floor, again with 90 ° of last layer book supporting board upsets downwards, put on cross-tie, successively adorn book, until top layer.Get book from top layer from the book car, getting book when top layer finishes and begins from the second layer (is with the top layer ground floor ordering) when getting book, earlier the top layer book supporting board is upwards overturn 90 °, and it is adsorbed on the magnetic on the bracket upright post, and then get book from the second layer, the rest may be inferred, from top to bottom until bottom.
