Description

Technical Field

[0001] This invention relates to the field of library management, and more specifically to a book restoration device. Background Technology

[0002] After being handled and viewed for a long time, books in the library inevitably develop creases or folds. To ensure the quality of the books, staff will first manually smooth out the creases or folds, and then stack books of similar size together to flatten them. However, the pressure between the stacked books is relatively weak, and the flattening effect is not ideal. Summary of the Invention

[0003] The purpose of this invention is to provide a book repair device that can efficiently flatten books, thereby solving the problem that existing books have poorly flattened edges.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A book restoration device includes a pressurizing component and a pressure-holding component. The pressurizing component includes a support arm with a vertically extending pressurizing screw threaded onto the support arm. A pressurizing seat is rotatably mounted on the lower end of the pressurizing screw. The pressure-holding component includes a base plate with a vertically extending guide post fixedly mounted on the top of the base plate. Several shelves are fitted on the guide post, and books are respectively placed between two adjacent shelves and between the bottom shelf and the base plate. The upper end of the guide post has an external thread, and a nut for pressing down the top shelf is threaded onto the upper end of the guide post.

[0005] As a further improvement, a handwheel is fixedly installed at the upper end of the pressure screw.

[0006] As a further improvement, it also includes a platform, the top of which has a mounting slot for placing the base plate; the pressurization assembly is movably mounted on the platform.

[0007] As a further improvement, a strip-shaped groove is provided on the platform located on the side of the placement slot. An adjustment seat is slidably installed in the strip-shaped groove, and the lower end of the support arm is fixedly installed on the adjustment seat; the upper end of the support arm is bent towards the strip-shaped groove.

[0008] As a further improvement, a laterally extending slide rod is fixedly installed inside the strip groove, and the adjusting seat is slidably installed on the slide rod.

[0009] As a further improvement, an adjusting screw is rotatably installed inside the strip groove, parallel to the slide rod, and an adjusting seat is threaded onto the adjusting screw; one end of the adjusting screw passes through the outside of the platform and is fixedly installed with a crank handle.

[0010] As a further improvement, positioning frames are provided between two adjacent shelves and between the bottom shelf and the base plate. The positioning frames have rectangular slots that are the same size as the corresponding books. The rectangular slots penetrate the positioning frames vertically, and the corresponding books are located in the rectangular slots.

[0011] As a further improvement, round holes are provided at the four corners of the rectangular groove, and the four corners of the book are located in the corresponding round holes. The inner wall of the round hole does not contact the edge of the book.

[0012] As a further improvement, the positioning frame is fitted onto the guide post.

[0013] As a further improvement, a metal positioning post is fixedly installed at the bottom of the positioning frame, and slots for the positioning post to be inserted are provided at the top of the shelf and the top of the bottom plate. A magnet block for adsorbing the positioning post is fixedly installed in the slot.

[0014] Compared with the prior art, the present invention has the following advantages: 1. Place the assembled pressure-holding assembly under the pressure base. Turn the handwheel to drive the pressure screw to rotate in the forward direction. The pressure screw will then drive the pressure base to press down on the top shelf, thereby increasing the pressure on the books and achieving a better flattening effect. 2. After the pressure seat presses down on the top shelf, tighten the nut further. Then the pressure holding assembly can be removed from under the pressure seat, and the pressure seat can be used to press the next set of pressure holding assemblies. One set of pressure holding assemblies can be used in conjunction with multiple sets of pressure holding assemblies, which is convenient for pressing books flat in large batches. 3. By setting a positioning frame with a rectangular groove that matches the size of the corresponding book, the book is positioned in the rectangular groove, which can prevent the book from shifting when the pressure seat applies downward pressure, thus avoiding secondary damage to the book. 4. The rectangular groove has round holes at its four corners. The four corners of the book are located in the corresponding round holes. The inner wall of the round hole does not contact the edge of the book, which can reduce wear on the four corners of the book. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, a book restoration device includes a pressurizing component 1 and a pressure-holding component 2.

[0020] like Figure 2 As shown, the pressurizing assembly 1 includes a support arm 3. The high end of the support arm 3 is provided with a vertically through screw hole. A vertically extending pressurizing screw 4 is connected to the screw hole by a thread. The lower end of the pressurizing screw 4 is rotatably mounted with a pressurizing seat 5 via a bearing. In order to rotate the pressurizing screw 4 more easily, a handwheel 6 is fixedly mounted on the upper end of the pressurizing screw 4 by a bolt.

[0021] like Figures 3 to 6 As shown, the pressure holding assembly 2 includes a rectangular base plate 7. Vertically extending guide posts 8 are fixedly installed at the four top corners of the base plate 7 by bolts. Several layers 9 are fitted on the guide posts 8. Books 10 are provided between two adjacent layers 9 and between the bottom layer 9 and the base plate 7. The upper end of the guide post 8 is provided with external threads, and the upper end of the guide post 8 is threaded with a nut 11 for pressing down the top layer 9.

[0022] After smoothing out the wrinkles on the pages of books 10, the staff stacked multiple books 10 on top of the base plate 7, and placed a shelf 9 on top of each book 10. The shelf 9 was then fitted onto the guide post 8 to prevent it from shifting, and a nut 11 was screwed into the upper end of each guide post 8 for pre-locking. The assembled pressure-holding assembly 2 was placed under the pressure seat 5, and the handwheel 6 was turned to drive the pressure screw 4 to rotate forward. The pressure screw 4 then drove the pressure seat 5 to press down on the top shelf 9. The pressure seat 5 could more evenly compress the multiple books 10 and also increase the pressure on the books 10. The staff then further tightened the nuts 11 to maintain a uniform and stable pressure on the books 10 from the pressure-holding assembly 2. Finally, the pressure screw 4 was turned in the opposite direction to drive the pressure seat 5 to detach from the top shelf 9, and the pressure-holding assembly 2 was removed from under the pressure seat 5. After the book 10 is pressed by the pressure-holding component 2 for a certain period of time, the nut 11 can be loosened to remove the pressed and flattened book 10.

[0023] It also includes a platform 12, with support legs fixedly installed at the four corners of the bottom of the platform 12. The top right end of the platform 12 is provided with a mounting groove 13 for placing the base plate 7, which can prevent the base plate 7 from shifting at the top of the platform 12 when the pressure seat 5 applies downward pressure.

[0024] The pressurizing component 1 is movably mounted on the platform 12. The platform 12, located to the left of the mounting slot 13, is provided with a vertically penetrating strip groove 14. A horizontally extending slide rod 15 is fixedly installed in the strip groove 14 by bolts. Two slide rods 15 are arranged side by side. An adjusting seat 16 is slidably mounted on the two slide rods 15. The lower end of the support arm 3 is fixedly installed on the top of the adjusting seat 16 by bolts. The upper end of the support arm 3 bends to the right and toward the strip groove 14.

[0025] To facilitate the adjustment of the position of the support arm 3, an adjusting screw 17, which is parallel to the slide rod 15, is rotatably installed in the strip groove 14 via a bearing. The adjusting seat 16 is threaded onto the adjusting screw 17. The left end of the adjusting screw 17 extends through the outside of the stage 12 and is fixedly mounted with a crank handle 18.

[0026] After the pressure holding assembly 2 is assembled, place the base plate 7 of the pressure holding assembly 2 into the placement slot 13. First, rotate the adjusting screw 17 clockwise, causing the adjusting seat 16 and support arm 3 to move to the right and closer to the pressure holding assembly 2, until the support arm 3 moves the pressure seat 5 directly above the top shelf 9. Then, rotate the pressure screw 4 clockwise, causing the pressure seat 5 to press down on the top shelf 9. After the worker further tightens the nut 11, rotate the pressure screw 4 counterclockwise, causing the pressure seat 5 to disengage from the top shelf 9. Then, rotate the adjusting screw 17 counterclockwise, causing the adjusting seat 16 and support arm 3 to move to the left and away from the pressure holding assembly 2, until the support arm 3 moves the pressure seat 5 away from directly above the top shelf 9, so that the pressure holding assembly 2 can be removed from the platform 12.

[0027] To prevent the book 10 from shifting when the pressure seat 5 applies downward pressure, positioning frames 19 are provided between two adjacent shelves 9 and between the bottom shelf 9 and the base plate 7. The thickness of the positioning frame 19 is less than the thickness of the book 10. The positioning frame 19 is provided with a rectangular groove 20 that is the same size as the corresponding book 10. The rectangular groove 20 extends vertically through the positioning frame 19, and the corresponding book 10 is located in the rectangular groove 20.

[0028] To reduce wear on the four corners of the book 10, the rectangular groove 20 is provided with round holes 21 at the four corners. The four corners of the book 10 are located in the corresponding round holes 21, and the inner wall of the round holes 21 does not contact the edge of the book 10.

[0029] To prevent the positioning frame 19 from shifting, the positioning frame 19 is fitted onto the guide post 8. Both the positioning frame 19 and the shelf 9 are provided with through holes for the guide post 8 to pass through.

[0030] The bottom of the positioning frame 19 is embedded with a metal positioning post 22. The top of the shelf 9 and the top of the bottom plate 7 are provided with slots 23 for the positioning post 22 to be inserted. The slots 23 are embedded with magnets 24 for adsorbing the positioning post 22, so that the positioning frame 19 can be effectively attached to the top of the shelf 9 or the top of the bottom plate 7, preventing the positioning frame 19 from moving around.
