In this embodiment, two symmetrically arranged rotating plates 8 are disposed in each circular hole 5, the outer sides of the two rotating plates 8 are rotationally fixed in the circular holes 5 through arc-shaped clamping strips (not shown in the figure) and annular clamping grooves 6, the distance between the two rotating plates 8 is 8cm and connected and fixed through a "[ -shaped connecting plate 12, so that the two rotating plates 8 can rotate in the circular holes 5, thereby realizing rotation or inclination of the supporting plate 4, and facilitating manual adjustment of readers. In addition, the radius of the round holes 5 is equal, the distance between two intersecting points of adjacent round holes 5 is 1.25 times of the radius of the round holes 5, the design is adopted, the connection rod 14 is convenient to transition between different round holes 5, the design of the distance between the intersecting points can be realized, the supporting unit 7 can be rotated to a vertical state, and then the supporting unit is taken out from the round holes 5. The book blocking rod 15 and the book blocking plate 16 are arranged to prevent books from falling when the supporting plate 4 rotates and inclines.
Since the handle 19 is hinged to the upper surface of the second gear 18, the handle 19 can swing up and down within a certain range, thereby realizing the fixing of the handle 19 in the yoke 35 or the removal from the yoke 35. When the handle 19 is rotated, the second gear 18 can be driven to rotate, and the second gear 18 is meshed with the first gear 17 to further drive the first gear 17 to rotate, so that the radius of the first gear 17 is larger than that of the second gear 18, and a larger thrust can be provided for driving of the embodiment under the action of the lever principle, so that the operation of a reader is labor-saving. Because the first and second grooves 23, 24 are disposed in the front-rear direction, when the first gear 17 drives the first and second shafts 25, 26 to rotate, the first and second shafts 25, 26 can slide in the first and second grooves 23, 24, respectively, so as to slide the first and second elastic plates 21, 22 left and right.
The track frame 20 is designed to limit the movement track of the first elastic plate 21 and the second elastic plate 22, so that the first elastic plate 21 and the second elastic plate 22 can only slide left and right. Since the left end of the first elastic plate 21 and the right end of the second elastic plate 22 are both arc-shaped, when they extend outwards, they can be snapped into the first groove 27 and the second groove 28, in order to ensure that they are snapped into the first groove 27 and the second groove 28, in this embodiment, further, a first clip rod 29 that can be inserted into the first groove 27 is provided at the left end of the first elastic plate 21, and a second clip rod 44 that can be inserted into the second groove 28 is provided at the right end of the second elastic plate 22. When the first elastic plate 21 and the second elastic plate 22 continue to extend outwards, an upward pushing force is provided for the support plate 4 due to the interaction of forces, so that the connecting rod 14 moves upwards from the bar-shaped clamping groove 10, then the support plate 4 is controlled to move downwards, the connecting rod 14 enters the next round hole 5 downwards from between the two rotating plates 8, then the distance between the two connecting rods 14 is increased under the pushing of the telescopic spring 33, and the connecting rod falls into the next bar-shaped clamping groove 10 under the guiding of the first slope part 9, so that the downward movement of the support plate 4 is realized.
Similarly, when the support plate 4 needs to move upwards, the handle 19 is turned to enable the connecting rod 14 to move upwards out of the bar-shaped clamping groove 10 and move upwards into the previous round hole 5, and the connecting rod enters the previous bar-shaped clamping groove 10 under the guidance of the second slope part 11, so that the upward movement of the support plate 4 is realized. The above actions can be achieved by different rotation angles of the handle 19, and the control of the rotation angles can be achieved by means of the plurality of clips 35 arranged on the lower surface of the support plate 4 during specific operation.
The vertical rods 31 are designed such that the connecting rods 14 can only perform relative translational movement, a telescopic spring 33 is connected between the two vertical rods 31, so as to provide a thrust force for the two connecting rods 14 in opposite directions, and when the connecting rods 14 move to the next round hole 5, the two connecting rods 14 are separated under the action of the telescopic spring 33, and then enter the strip-shaped clamping groove 10 under the guidance of the first slope part 9. When the connecting rod 14 moves to the previous round hole 5, the two connecting rods 14 are separated under the action of the telescopic spring 33, and then enter the bar-shaped clamping groove 10 under the guidance of the second slope part 11. The baffle 32 is designed to fix the connecting rod 14 to the supporting unit 7 to prevent the connecting rod from falling out.
The books placed on the support plate 4 need to be fixedly pressed, especially when the reader takes a book or basic book from the book, the nearby books can be laterally fallen due to the loss of support, and for this purpose, the falling-preventing structure 36 is provided, and the falling-preventing structure 36 can be arranged at the edge of the books in a row or can be placed in the middle of the books in a row. Because the sleeve 37 can move and rotate on the book blocking rod 15, the anti-falling structure 36 can be moved to a required place, and then the elastic washer 42 is extruded by rotating the cover body, so that the elastic washer 42 is extruded on the book blocking rod 15, and the position of the anti-falling structure 36 is fixed.
The two book blocking sheets 38 are pushed by the first spring 39 and the second spring 40 to move away from each other, when a reader takes one book or several books from a row of books, the anti-falling structure 36 can be moved to a book taking position, and the two book blocking sheets 38 are inserted into a neutral space left after the book is taken, so that the fixation of the row of books is realized, and the lateral falling of the books is avoided.
In conclusion, the book lifting device has the advantages of being capable of manually lifting and achieving book inclination, and is suitable for wide popularization and application.
The present invention is not described in detail in the present application, and is well known to those skilled in the art. Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
