Description

Technical Field

[0001] The present invention relates to the field of radio frequency identification technology, and in particular to a book-finding device that cooperates with a positioning module of a book device using radio frequency identification technology. Background Art

[0002] For a long time, library inventory, search, library classification and shelving have been relatively tedious tasks, which require a lot of time and manpower to complete. Not only does it waste a lot of time, it also reduces the enthusiasm of relevant staff and reduces the satisfaction of readers. How to solve these problems has always troubled the library staff. With the development of the Internet of Things, RFID technology (i.e. radio frequency identification technology) has become more and more mature and has great advantages in book management. With the help of RFID wireless radio frequency identification technology, self-service borrowing and returning, fast inventory, fast query, positioning, shelving, and sorting in libraries have become a reality.

[0003] When using RFID technology, it is necessary to stick RFID tags on the surface of books. By scanning books with RFID tags, shelf information and document address information of circulation library documents can be collected to help shelving, search and statistics of specific circulation materials. In the prior art, RFID tags are only stuck on the surface of books. If the borrower peels off the RFID tag from the book, or directly tears off the page with the RFID tag, the RFID system's recognition of the book will be destroyed, and the RFID system will not be able to identify the status of the book, making it impossible for the library to monitor books without RFID tags.

[0004] In addition, libraries will hide RFID tags inside the spines of books, which requires cutting grooves in the spines of books. For some precious books, cutting grooves in the spines of books will damage the value of the books. Therefore, it is not appropriate to hide RFID tags inside the spines of precious books.

[0005] In view of this, the present invention proposes a positioning module of a book device using radio frequency identification technology in cooperation with a book-finding device to make up for and improve the deficiencies of the prior art. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a book-finding device in cooperation with a positioning module of a book device using radio frequency identification technology to solve the corresponding technical problems raised in the above background technology.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows: A positioning module collaborative book-finding device for a radio frequency identification technology book device, including a protective shell. A screw rod is arranged in the inner cavity of the protective shell. The protective shell is symmetrically provided with notch openings on one side in a shape of an eight, and a fixing structure for fixing the protective shell on the surface of the book is arranged on one side of the notch opening. The fixing structure includes clamping plates symmetrically arranged outside the notch opening, and the mutually approaching sides of the two clamping plates are parallel to each other;

[0008] An inner shell is fixedly connected inside the protective shell, and a limiting component for preventing the clamping plates from moving is arranged inside the inner shell. The limiting component includes a rotating shaft penetrating through the bottom of the inner shell, and the rotating shaft is rotatably connected with the inner shell. The rotating shaft is rotatably connected with the inner shell through a bearing.

[0009] Furthermore, the fixing structure further includes a slider and a guide rod. The slider is fixedly connected to the bottom of the clamping plate, and the slider penetrates through the notch opening and extends into the protective shell. The guide rod is slidably penetrated by the slider, and the extending direction of the guide rod is the same as the extending direction of the notch opening.

[0010] Furthermore, the limiting component further includes a connecting pin and a spring. The connecting pin longitudinally slides through the rotating shaft, and a spring is arranged in the cavity of the rotating shaft. The spring is sleeved outside the connecting pin, and the spring is located below the middle protrusion of the connecting pin.

[0011] Furthermore, the connecting pin has a cuboid structure, and a plurality of card slots are annularly arranged on the outer side of the top end of the connecting pin.

[0012] Furthermore, a T-shaped rotating wrench is arranged inside the inner shell. A sleeve is fixedly connected to the bottom of the rotating wrench, and the sleeve is sleeved on the top end of the connecting pin. The sleeve can be removed from the top of the connecting pin. A plurality of clamping blocks are fixedly connected in a ring shape on the inner wall of the sleeve, and the clamping blocks are matched with the card slots.

[0013] Furthermore, a connecting block is fixedly connected inside the protective shell. The side surface of the connecting block is fixedly connected with the guide rod. A moving block is threadedly connected to the middle of the screw rod. A sliding rod is fixedly connected to the moving block, and both ends of the sliding rod slidably penetrate through both sides of the slider.

[0014] Furthermore, the top of the screw rod horizontally rotates through both sides of the connecting block. A groove is opened at the top of the screw rod, and the groove is matched with the connecting pin. The bottom of the screw rod horizontally rotates through both sides of the fixed block, and a ratchet wheel is fixedly connected to the bottom of the screw rod.

[0015] Furthermore, a ratchet pawl is arranged on one side of the ratchet wheel. One end of the ratchet pawl is rotatably connected to the inner wall of the protective shell through a rotating shaft, and the other end of the ratchet pawl is meshed with the ratchet wheel. A through hole is opened on the side surface of the ratchet pawl. A metal reed is arranged on the side of the ratchet pawl away from the ratchet wheel. The metal reed is fixedly connected to the inner wall of the protective shell, and the metal reed is slidably connected to the side surface of the ratchet pawl. Under the elastic force of the metal reed, the ratchet pawl is kept meshed with the ratchet wheel.

[0016] Furthermore, anti-slip pointed cones are fixedly connected to the inner side of the splint, and the tips of the anti-slip pointed cones incline towards the side close to the protective case.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) By providing a protective case, after pasting the RFID tag on the outer side of the book spine of the book, and then covering the protective case outside the RFID tag, the protective case is used to block the RFID tag on the side of the book spine, so that readers cannot directly contact the RFID tag, thus preventing readers from directly tearing off the RFID tag from the book. Moreover, by pasting the RFID tag on the outer side of the book spine, it can be avoided that the RFID tag is torn off together with the book pages. Using the protective case to provide protection for the RFID tag can reduce the occurrence of the RFID tag of the book being torn off.

[0019] (2) By providing a fixing structure, two symmetrical splints are used to clamp on both sides of the book spine, so that the protective case can be closely attached to the outer side of the book spine. For some precious books, the RFID tag can be pasted on the inner side of the protective case, and then the protective case is closely attached to the outer side of the book spine, and the RFID tag can be connected to the book without damaging the surface of the book, thus avoiding damaging the book and reducing the occurrence of damaging precious books.

[0020] (3) Through the provided limiting component, after the protective case is closely attached to the side of the book spine, the turning wrench needs to be removed from the inner shell. In this way, under the elastic force of the spring, the connecting pin is pushed to move vertically in the rotating shaft. At this time, the bottom of the connecting pin disengages from the groove at the top of the screw. After the protective case is fixed on the outer side of the book spine, if the reader does not have the turning wrench, they cannot drive the screw to rotate by rotating the rotating shaft, and the screw cannot rotate, so the clamping of the splint on the book spine cannot be released. Finally, under the protection of the limiting component, it can be avoided that the reader uses force to remove the protective case, increasing the difficulty for the reader to damage the RFID tag.

[0021] (4) By providing a ratchet at the bottom of the screw and a pawl on the side of the ratchet, through the cooperation of the pawl and the ratchet, when the pawl meshes with the ratchet, the pawl can prevent the ratchet from reversing. In this way, after the splint is driven by the screw to clamp on both sides of the book spine, the pawl is used to prevent the ratchet from reversing, which can avoid the screw from reversing and thus avoid the splint from loosening from both sides of the book spine.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1 of the present invention

[0036] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 10As shown in the figure, a positioning module cooperative book-finding device for radio frequency identification technology includes a protective case 1. Inside the inner cavity of the protective case 1, a screw rod 4 is arranged. On one side of the protective case 1, notch openings 2 are symmetrically arranged in a V-shape. On one side of the notch openings 2, a fixing structure 3 for fixing the protective case 1 on the surface of the book is arranged. The fixing structure 3 includes clamping plates 31 symmetrically arranged outside the notch openings 2;

[0037] Inside the protective case 1, an inner case 13 is fixedly connected. Inside the inner case 13, a limiting component 8 for preventing the movement of the clamping plates 31 is arranged. The limiting component 8 includes a rotating shaft 81 penetrating the bottom of the inner case 13, and the rotating shaft 81 is rotatably connected to the inner case 13.

[0038] The fixing structure 3 further includes a slider 32 and a guiding rod 33. The slider 32 is fixedly connected to the bottom of the clamping plate 31, and the slider 32 penetrates through the notch opening 2 and extends into the protective case 1. The guiding rod 33 is slidably penetrated by the slider 32, and the extending direction of the guiding rod 33 is the same as the extending direction of the notch opening 2. The screw rod 4 drives the moving block 5 to move. The moving block 5 drives the slider 32 to slide on the guiding rod 33 through the sliding rod 6. By driving the clamping plates 31 outside the protective case 1 to approach each other through the slider 32, the clamping plates 31 are held on both sides of the book spine through the anti-slip pointed cones 19 on the sides of the clamping plates 31. Finally, the protective case 1 is fixed on the outside of the book spine of the book, and the protective case 1 is used to provide protection for the RFID tag.

[0039] Inside the protective case 1, a connecting block 7 is fixedly connected. The side of the connecting block 7 is fixedly connected to the guiding rod 33. In the middle of the screw rod 4, a moving block 5 is threadedly connected. The moving block 5 is fixedly connected to a sliding rod 6, and both ends of the sliding rod 6 slidably penetrate through both sides of the slider 32. When the slider 32 moves along the guiding rod 33, the slider 32 synchronously slides along the sliding rod 6.

[0040] Anti-slip pointed cones 19 are fixedly connected to the inner sides of the clamping plates 31, and the tips of the anti-slip pointed cones 19 incline towards the side close to the protective case 1. After the clamping plates 31 are held on both sides of the book spine, the anti-slip pointed cones 19 are embedded into both sides of the book, increasing the friction between the clamping plates 31 and the book.

[0041] The effects achieved by this embodiment are as follows: Compared with the prior art, by arranging the protective case 1 and cooperating with the fixing structure 3, the protective case 1 can be closely attached to the outside of the book spine, so that the RFID tag can be kept between the protective case 1 and the book spine. Moreover, through the fixing structure 3, readers can be prevented from directly tearing off the RFID tag from the book, providing protection for the RFID tag, and reducing the occurrence of the situation where the RFID tag of the book is torn off. For some precious books, the RFID tag can be pasted on the inner side of the protective case 1, and then the protective case 1 can be closely attached to the outside of the book spine, connecting the RFID tag to the book without damaging the surface of the book, thereby avoiding damaging the book and reducing the occurrence of the situation of damaging precious books.

[0042] Embodiment 2 of the present invention

[0043] Please refer to Figure 6 、 Figure 7 、 Figure 8 As shown, the limiting component 8 further includes a connecting pin 82 and a spring 83. The connecting pin 82 longitudinally slides through the rotating shaft 81. A spring 83 is arranged in the cavity of the rotating shaft 81. The spring 83 is sleeved outside the connecting pin 82. The spring 83 is located below the middle protrusion of the connecting pin 82.

[0044] The connecting pin 82 has a cuboid structure, and a plurality of card slots 9 are annularly arranged on the outer side of the top end of the connecting pin 82.

[0045] A T-shaped wrench 10 is arranged inside the inner housing 13. A sleeve 12 is fixedly connected to the bottom of the wrench 10. The sleeve 12 is sleeved on the top end of the connecting pin 82. A plurality of clamping blocks 11 are fixedly connected to the inner wall of the sleeve 12 in a ring shape. The clamping blocks 11 are matched with the card slots 9. The wrench 10 is inserted into the inner housing 13, and the sleeve 12 is kept sleeved on the top of the rotating shaft 81. The sleeve 12 is pressed down forcefully so that the clamping blocks 11 are inserted into the card slots 9 on the top of the rotating shaft 81 one by one. During the pressing process of the sleeve 12, the inner top surface of the sleeve 12 pushes the connecting pin 82 to move vertically downward, so that the bottom of the connecting pin 82 is inserted into the groove 20 on the top of the screw 4. Since the groove 20 is matched with the connecting pin 82, the rotating shaft 81 is integrated with the screw 4 through the connecting pin 82 and the screw 4.

[0046] The top of the screw 4 horizontally rotates through both sides of the connecting block 7. A groove 20 is opened at the top of the screw 4. The groove 20 is matched with the connecting pin 82. The bottom of the screw 4 horizontally rotates through both sides of the fixed block 18. A ratchet 14 is fixedly connected to the bottom of the screw 4.

[0047] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting the limiting component 8, after the wrench 10 drives the sleeve 12 to separate from the inner housing 13, under the elastic force of the spring 83, the connecting pin 82 vertically rises, and the bottom of the connecting pin 82 separates from the groove 20 on the top of the screw 4. In this way, without the wrench 10, the screw 4 cannot be driven to rotate synchronously by rotating the rotating shaft 81, thereby preventing the reader from being unable to release the clamping of the book spine by the clamping plate 31 without the wrench 10 and increasing the difficulty for the reader to damage the protective shell 1.

[0048] Embodiment 3 of the present invention

[0049] Please refer to Figure 1 、 Figure 2 、 Figure 9As shown, a pawl 15 is provided on one side of the ratchet 14, one end of the pawl 15 is rotatably connected to the inner wall of the protective shell 1 through a rotating shaft, and the other end of the pawl 15 is meshed with the ratchet 14. A through hole 17 is provided on the side of the pawl 15, and a metal spring 16 is provided on the side of the pawl 15 away from the ratchet 14. The metal spring 16 is fixedly connected to the inner wall of the protective shell 1, and the metal spring 16 is slidably connected to the side of the pawl 15. Under the action of the pawl 15, the ratchet 14 can be prevented from reversing, thereby preventing the screw 4 from reversing. When the protective shell 1 needs to be removed from the outside of the spine, a steel needle is used to pass through the slide groove at the bottom of the protective shell 1, so that the steel needle is inserted into the through hole 17, and the pawl 15 is driven to release the meshing relationship with the ratchet 14 by turning the steel needle, and the screw 4 can be rotated in the opposite direction at this time.

[0050] The effects achieved by this embodiment are as follows: compared with the prior art, through the mutual cooperation of the ratchet 14 and the pawl 15, when the ratchet 14 and the pawl 15 are engaged, the pawl 15 can prevent the ratchet 14 from reversing. In this way, after the screw 4 drives the clamp 31 to clamp both sides of the spine, the pawl 15 is used to prevent the ratchet 14 from reversing. In this way, the screw 4 can be prevented from reversing, thereby preventing the clamp 31 from loosening from both sides of the spine, so that the clamp 31 is firmly clamped on both sides of the spine, preventing the protective shell 1 from falling off from the outside of the spine after long-term use.

[0051] The working process and principle of the overall contents of the above-mentioned embodiments 1 to 3 are as follows:

[0052] When using RFID technology (i.e. radio frequency identification technology) for book management, it is necessary to connect the RFID tag to the book and install the RFID device on the bookshelf. The RFID reader automatically identifies the RFID tag through the antennas deployed on both sides of the device. The bookshelf can read the RFID tag of each book on the shelf and extract the keyword information of the book carried by the tag to facilitate reading of books on each shelf.

[0053] After pasting the RFID tag on the outer side of the book spine, closely attach the protective case 1 to the outer side of the book spine, keep the RFID tag between the book spine and the protective case 1, then insert the rotating wrench 10 into the inner housing 13, keep the sleeve 12 sleeved on the top of the rotating shaft 81, press down the sleeve 12 forcefully so that the locking blocks 11 are inserted into the card slots 9 on the top of the rotating shaft 81 one by one. During the process of pressing down the sleeve 12, the inner top surface of the sleeve 12 pushes the connecting pin 82 to move vertically downward, so that the bottom of the connecting pin 82 is inserted into the groove 20 on the top of the screw rod 4. Since the groove 20 and the connecting pin 82 match each other, in this way, the rotating shaft 81 is connected to the screw rod 4 through the connecting pin 82. At this time, rotate the rotating wrench 10 to drive the rotating shaft 81 to rotate, drive the screw rod 4 to rotate synchronously through the connection of the connecting pin 82, the screw rod 4 drives the moving block 5 to move, the moving block 5 drives the slider 32 to slide on the guide rod 33 through the slide rod 6, drive the clamping plates 31 outside the protective case 1 to approach each other through the slider 32, and keep the clamping plates 31 clamped on both sides of the book spine through the anti-slip pointed cones 19 on the side surfaces of the clamping plates 31. Finally, fix the protective case 1 on the outer side of the book spine of the book. Using the protective case 1 to provide protection for the RFID tag can reduce the situation that the RFID tag of the book is torn off.

[0054] When dealing with some precious books, when pasting the RFID tag on the surface of the book, the adhesive of the RFID tag may damage the book. At this time, the RFID tag can be pasted on the inner side of the protective case 1, then closely attach the protective case 1 to the outer side of the book spine. After that, insert the rotating wrench 10 into the inner housing 13, press down the sleeve 12 forcefully so that the locking blocks 11 are inserted into the card slots 9 on the top of the rotating shaft 81 one by one. During the process of pressing down the sleeve 12, the inner top surface of the sleeve 12 pushes the connecting pin 82 to move vertically downward, so that the bottom of the connecting pin 82 is inserted into the groove 20 on the top of the screw rod 4. Rotate the rotating wrench 10 to drive the rotating shaft 81 to rotate, drive the screw rod 4 to rotate synchronously through the connection of the connecting pin 82, the screw rod 4 drives the moving block 5 to move, the moving block 5 drives the slider 32 to slide on the guide rod 33 through the slide rod 6, drive the clamping plates 31 outside the protective case 1 to approach each other through the slider 32, the clamping plates 31 are clamped on both sides of the book spine, and finally fix the protective case 1 on the outer side of the book spine of the book, so that the RFID tag can be connected to the book without damaging the surface of the book, thus avoiding damaging the book and reducing the occurrence of damaging precious books.

[0055] After the clamping plate 31 is clamped on both sides of the book spine, the ratchet 14 can be prevented from reversing under the action of the pawl 15, thereby preventing the screw 4 from reversing. Then the rotating wrench 10 is taken out of the inner shell 13. The rotating wrench 10 is kept separately by the librarian. When the rotating wrench 10 is removed from the top of the rotating shaft 81, the elastic force of the spring 83 causes the connecting pin 82 to disengage from the groove 20 at the top of the screw 4, so that the rotating shaft 81 is disconnected from the screw 4. After the protective shell 1 is fixed to the outside of the book spine, if the reader does not rotate the wrench 10, the screw 4 cannot be driven to rotate by rotating the rotating shaft 81. If the screw 4 cannot rotate, the clamping plate 31 on the book spine cannot be released. Finally, under the protection of the limiting component 8, the reader can be prevented from removing the protective shell 1 by rotating the screw 4, thereby increasing the difficulty for the reader to damage the RFID tag.

[0056] When the protective shell 1 needs to be removed from the outer side of the spine, a steel needle is used to pass through the slide groove at the bottom of the protective shell 1 so that the steel needle is inserted into the through hole 17. The pawl 15 is driven to release the meshing relationship with the ratchet 14 by toggling the steel needle. Then, the rotating wrench 10 is inserted into the inner shell 13, and the sleeve 12 is kept sleeved on the top of the rotating shaft 81. The sleeve 12 is pressed down with force so that the blocks 11 are inserted into the card slots 9 at the top of the rotating shaft 81 one by one. During the process of pressing the sleeve 12 down, the inner top surface of the sleeve 12 pushes the connecting pin 82 to move vertically downward, so that the bottom of the connecting pin 82 is inserted into the The rotating shaft 81 is inserted into the groove 20 at the top of the screw 4, and the rotating shaft 81 is connected to the screw 4 through the connecting pin 82. The reverse rotation of the rotating wrench 10 drives the rotating shaft 81 to rotate in the reverse direction. The connection of the connecting pin 82 drives the screw 4 to rotate in the reverse direction synchronously. The screw 4 drives the moving block 5 to move in the reverse direction. The moving block 5 drives the slider 32 to slide in the reverse direction on the guide rod 33 through the sliding rod 6. The clamping plate 31 outside the protective shell 1 is driven to move away from each other through the slider 32, so that the clamping fixation of the clamping plate 31 on the spine can be released, and the protective shell 1 can be finally removed from the outside of the spine.
