Description

Technical Field

[0001] This invention relates to the field of bookshelf technology, specifically to a bookshelf with a function of protecting books. Background Technology

[0002] A bookshelf is a container used specifically to store books. Due to differences in shape and structure, bookshelves are also known as bookcases, book cabinets, book dividers, and other names. Bookshelves are common items in our lives. Bookshelves can be divided into metal bookshelves and wooden bookshelves according to their materials. Metal bookshelves can be further subdivided into single-column, multi-column, stacked, compact, and sliding bookshelves.

[0003] Bookshelves are an indispensable infrastructure in library management and services. Their core function is to store and protect books efficiently and in an orderly manner. By storing books in a reasonable category, they not only make it easier for readers to find and borrow books, but also facilitate management and inventory by librarians. Bookshelves provide a good storage environment for books by providing stable storage space.

[0004] In the existing technology, some valuable books are stored in libraries or collections. When readers borrow or return books, they may carelessly cause books placed together to fall off the shelves, thus damaging the books. In addition, when books are placed on open shelves, dust will fall on the books over a long period of time, causing the books to become dirty. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a bookshelf with a book protection function to solve the technical problems that when readers borrow and return books, books placed together may fall off the bookshelf, and dust will fall on the books after a long time, thus making the books dirty.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bookshelf with a book protection function, comprising a bookshelf body, wherein multiple sets of placement mechanisms are arranged inside the bookshelf body, multiple sets of protective mechanisms are installed inside the placement mechanisms, an opening mechanism is provided between the protective mechanisms and the placement mechanisms, a closing mechanism is provided at the bottom of one side of the protective mechanisms, a clamping mechanism is installed inside the protective mechanisms, the placement mechanism includes a placement shell, wherein the placement shell is disposed inside the bookshelf body, the protective mechanism includes a fixed shell, a movable shell and a protective door, wherein the fixed shell is fixedly connected to the placement shell by bolts, the movable shell is slidably connected to the fixed shell, the protective door is rotatably connected to one side of the fixed shell, and the fixed shell, the movable shell and the protective door together play the role of protecting the books, the closing mechanism includes a rotating shaft, a torsion spring and a pull rope, wherein the rotating shaft is movably installed at the bottom of one side of the movable shell, the torsion spring is installed at the top of the rotating shaft, one end of the pull rope is fixed to the outer wall of the rotating shaft, and the other end of the pull rope passes through the fixed shell and is fixedly connected to the protective door.

[0007] By adopting the above technical solution, this invention places books in a relatively enclosed environment by setting up multiple sets of built-in protective mechanisms, effectively isolating them from external dust pollution. During borrowing, the protective case containing the book automatically slides out and unlocks, facilitating easy access. Upon return, after the book is placed back into the protective case, a closing mechanism is automatically triggered, ensuring the protective door is securely closed and locked. The automated closing process eliminates the risk of forgetting to close the door due to human negligence, ensuring that the books are always protected and reducing the possibility of damage caused by accidental drops or exposure. In addition, a ventilation module is designed inside the bookshelf, which continuously promotes air circulation inside the protective mechanism through a duct connected to an external fan, effectively preventing books from getting damp and moldy, further extending the lifespan of precious books. This solves the technical problems that may occur when readers borrow and return books, causing books placed together to fall off the shelf, and that dust may accumulate on books after prolonged storage, thus causing them to become dirty.

[0008] Furthermore, the closing mechanism also includes a fixed base and a fixing member. The fixed base is fixedly installed on the bottom of one side of the movable shell. The top inner side of the fixed base is fixedly connected to the fixing member. The torsion spring is located inside the fixing member, and the rotating shaft is elastically connected to the fixing member through the torsion spring. The rotating shaft and the fixed base are rotatably connected. The closing mechanism also includes a limiting rod, a rotating rod, a movable plate, a limiting plate, a push plate, and a push rod. The limiting rod is fixedly installed on one side of the rotating shaft. The rotating rod is rotatably connected to the top side of the fixing member. The other end of the rotating rod is fixedly connected to the movable plate. The limiting plate is fixedly installed on one side of the fixing member. A spring is installed between the movable plate and the limiting plate, and the movable plate is elastically connected to the limiting plate through the spring. The push plate is fixedly installed on the top of the movable plate. The push rod is fixedly installed on the bottom of one side of the movable shell, and the push rod and the push plate are at the same level.

[0009] By adopting the above technical solution, a pull rope is installed on the bottom inner side of the protective door. During the passive opening of the protective door, the pull rope is pulled, and the other end of the pull rope is fixed to a rotating shaft. A torsion spring is installed on the top of the rotating shaft and is installed inside the fixing component. Therefore, after the pull rope is pulled by the protective door, the rotating shaft will be pulled to rotate, causing the torsion spring to accumulate elastic potential energy. A limit rod is installed on one side of the rotating shaft. During the rotation of the rotating shaft, the limit rod will rotate along with it until it passes the movable plate. The movable plate is connected to the fixing component through a rotating rod, and a spring is set between the movable plate and the limit plate. Therefore, after the limit rod passes the movable plate, the movable plate will quickly return to its original position and fit tightly against the limit plate. Therefore, when the protective door is opened, when the torsion spring releases its elastic potential energy, it will cause the rotating shaft to return to its original position. However, after the limit rod passes the movable plate, when the rotating shaft returns to its original position, the limit rod will be blocked by the movable plate, thus preventing the rotating shaft from returning to its original position. Therefore, the elastic potential energy of the torsion spring will not be fully released, thus ensuring that the protective door will not close.

[0010] Furthermore, the protection mechanism also includes a handle and a first electromagnetic lock, wherein the handle is fixedly installed on one side of the movable shell, the first electromagnetic lock is fixedly installed on one end of the inner side of the movable shell, and the first electromagnetic lock serves to restrict the protective door. The protection mechanism also includes a pulley and a slide rail, wherein the pulley is movably installed at the bottom of the movable shell, the slide rail is opened inside the fixed shell, and the pulley and the slide rail are movably connected.

[0011] By adopting the above technical solution, the push plate is installed on the top of the movable plate. When the push plate is pushed, the movable plate will rotate around the rotating rod, which will release the restriction of the limit rod. The torsion spring will then completely release its elastic potential energy, causing the rotating shaft and the limit rod to reset. The rotating shaft will then wind up the pull rope, thereby pulling the protective door and closing it. The first electromagnetic lock will then lock the protective door, thus completing the automatic closing of the protective door. This prevents users from forgetting to close the protective door when returning books and also prevents external dust from contaminating the books.

[0012] Furthermore, the clamping mechanism includes a clamping plate, a first inclined block, a second inclined block, a telescopic block, a sliding block, a driving block, and a movable groove. The clamping plate is movably installed at the bottom of the inner side of the movable shell. The first inclined block is fixedly installed at one end of the inner side of the fixed shell. The second inclined block is fixedly installed at the other end of the inner side of the fixed shell. The telescopic block is fixedly installed at the bottom of one side of the clamping plate. One side of the telescopic block is movably connected to the sliding block. The sliding block has inclined surfaces at both ends, and the inclined surfaces at both ends of the sliding block respectively cooperate with the inclined surfaces of the first inclined block and the second inclined block. The top of the sliding block is fixedly connected to the driving block. The driving block is slidably connected to the movable shell through the movable groove.

[0013] By adopting the above technical solution, the inclined surface of one side of the sliding block will contact the inclined surface of the second inclined block, and then the sliding block will passively move along the inclined surface of the second inclined block, thereby driving the clamping plate to move towards the book through the telescopic block. On the opposite side of the clamping plate inside the movable shell, an elastic block is installed, so the clamping plate will push the book towards the elastic block, thereby completing the clamping of the book, preventing the book from tipping over inside the movable shell and avoiding damage to the book. The clamping plate and the sliding block are connected by the telescopic block. When the book has a large thickness, the clamping plate will squeeze the book under the action of the sliding block, while the other side of the book contacts the elastic block until the book is clamped and fixed. At this time, the sliding block continues to move, causing the clamping plate to squeeze the telescopic block in the opposite direction. An elastic mechanism is installed inside the telescopic block, which can realize the elastic connection between the clamping plate and the sliding block. Therefore, under the action of the telescopic block, the clamping plate will shorten the distance between itself and the sliding block, thereby realizing the adaptive clamping mechanism to the thickness of the book.

[0014] Furthermore, the door opening mechanism includes a fixed plate, a U-shaped ring, a magnetic repulsion block, a second electromagnetic lock, and an electromagnet. The fixed plate is fixedly installed at one end of the movable shell, the U-shaped ring is fixedly installed on the top of the outer wall of the fixed plate, the magnetic repulsion block is fixedly installed on one side of the fixed plate, the second electromagnetic lock is fixedly installed inside the placement shell and serves to lock the U-shaped ring, and the electromagnet is fixedly installed inside the placement shell, and the magnetic field of the electromagnet when energized is repulsive to the magnetic field of the magnetic repulsion block.

[0015] By adopting the above technical solution, the door opening mechanism is installed on the back of the protection mechanism. The second electromagnetic lock installed on the placement shell will receive an electrical signal and be energized and closed in a short time, thereby releasing the restriction on the U-shaped ring. At the same time, the electromagnet installed on the placement shell will also be energized in a short time. At this time, the electromagnet will generate a magnetic field. The magnetic repulsion block is installed on the back of the movable shell through a fixing plate. The magnetic repulsion block itself always has magnetism, and its magnetic field is repulsive to the magnetic field generated by the energized electromagnet.

[0016] Furthermore, the placement mechanism also includes a ventilation pipe and an air vent. The ventilation pipe is fixedly installed on one side of the placement shell and is connected to an external fan. The air vent is located at the bottom of one side of the movable shell and serves to connect the inside and outside of the movable shell.

[0017] By adopting the above technical solution, the books are fixed inside the protective mechanism and will not be affected by external factors, so they will not fall off the bookshelf. A ventilation port is opened on the bottom back of the movable shell, and a ventilation pipe is opened at the same horizontal position on the side where the shell is placed. The ventilation pipe is connected to the external fan duct. When the books are protected, the fan will work continuously to circulate the air inside the protective mechanism through the ventilation pipe, preventing the books from getting damp and reducing their lifespan.

[0018] In summary, the present invention has the following beneficial effects: By setting up multiple sets of built-in protective mechanisms, the present invention places books in a relatively closed environment, effectively isolating them from external dust pollution. During the borrowing process, the protective cover containing the book automatically slides out and unlocks, making it convenient to pick up and put down. When returning the book, after it is put back into the protective cover, a closing mechanism is automatically triggered to ensure that the protective door is firmly closed and locked. The automated closing process eliminates the risk of forgetting to close the door due to human negligence, ensuring that the book is always protected and reducing the possibility of damage caused by accidental drops or exposure. In addition, a ventilation module is designed inside the bookshelf, which continuously promotes air circulation inside the protective mechanism through a duct connected to an external fan, effectively preventing the book from getting damp and moldy, further extending the preservation life of precious books. It solves the technical problems that when readers borrow and return books, books placed together may fall off the bookshelf, and dust will fall on the books after a long time, causing them to become dirty.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of the present invention will now be described.

[0034] A bookshelf with book protection function, such as Figure 1-12 As shown, the bookshelf includes a bookshelf body 1. The bookshelf body 1 has multiple sets of placement mechanisms 2 inside. The placement mechanisms 2 have multiple sets of protective mechanisms 3 inside. The protective mechanisms 3 and the placement mechanisms 2 are connected by an opening mechanism 4. The bottom of one side of the protective mechanism 3 is provided with a closing mechanism 5. The protective mechanism 3 has a clamping mechanism 6 inside. A smart book borrowing system is installed on one side of the bookshelf body 1. When borrowing books, users can borrow books through a smart panel. Inside the bookshelf body 1, multiple sets of placement mechanisms 2 are placed. Inside each set of placement mechanisms 2, multiple sets of protective mechanisms 3 are installed by bolts. Inside each set of protective mechanisms 3, there are books to be protected.

[0035] Furthermore, the placement mechanism 2 includes a placement shell 201, which is disposed inside the bookshelf body 1. The protection mechanism 3 includes a fixed shell 301, a movable shell 302, and a protective door 303. The fixed shell 301 is fixedly connected to the placement shell 201 by bolts. The movable shell 302 is slidably connected to the fixed shell 301. The protective door 303 is rotatably connected to one side of the fixed shell 301. The fixed shell 301, the movable shell 302, and the protective door 303 together play the role of protecting the books. The closing mechanism 5 includes a rotating shaft 503, a torsion spring 504, and a pull rope 505. The rotating shaft 503 is movably installed at the bottom end of one side of the movable shell 302. The torsion spring 504 is installed at the top of the rotating shaft 503. One end of the pull rope 505 is fixed to the outer wall of the rotating shaft 503, and the other end of the pull rope 505 passes through the fixed shell 301 and is fixedly connected to the protective door 303.

[0036] After the user selects a book via the smart panel, the book borrowing system can send electrical signals to the protective mechanism 3 and the opening mechanism 4, causing the movable shell 302 to move out. During the process of the movable shell 302 moving out of the fixed shell 301, the clamping mechanism 6 inside the movable shell 302 will also open simultaneously. After the movable shell 302 moves out of the fixed shell 301, the user can easily take the book out of the movable shell 302 and then push the movable shell 302 towards the fixed shell 301 via the handle 304. Then, the protective door 303 will be automatically closed by the closing mechanism 5. When the user returns the book, after the movable shell 302 moves out of the fixed shell 301 via the smart book borrowing system, the user places the book inside the movable shell 302 and then pushes the movable shell 302 towards the fixed shell 301 via the handle 304.

[0037] In the example, the closing mechanism 5 also includes a fixed base 501 and a fixing member 502. The fixed base 501 is fixedly installed on the bottom side of the movable housing 302, and the top inner side of the fixed base 501 is fixedly connected to the fixing member 502. A torsion spring 504 is located inside the fixing member 502, and the rotating shaft 503 is elastically connected to the fixing member 502 through the torsion spring 504. The rotating shaft 503 and the fixed base 501 are rotatably connected. The closing mechanism 5 also includes a limiting rod 506, a rotating rod 507, a movable plate 508, a limiting plate 509, a push plate 510, and a push rod 511, wherein the limiting rod 506... Rod 506 is fixedly installed on one side of rotating shaft 503. Rotating rod 507 is rotatably connected to the top side of fixed part 502. The other end of rotating rod 507 is fixedly connected to movable plate 508. Limiting plate 509 is fixedly installed on one side of fixed part 502. Push plate 510 is fixedly installed on the top of movable plate 508. Push rod 511 is fixedly installed on the bottom side of movable shell 302. Push rod 511 and push plate 510 are at the same level. A spring is installed between movable plate 508 and limiting plate 509. Movable plate 508 is elastically connected to limiting plate 509 through spring.

[0038] A pull rope 505 is installed on the inner bottom of the protective door 303. When the protective door 303 is passively opened, the pull rope 505 is pulled. The other end of the pull rope 505 is fixed to the rotating shaft 503, and a torsion spring 504 is installed on the top of the rotating shaft 503. The torsion spring 504 is installed inside the fixing component 502. Therefore, after the pull rope 505 is pulled by the protective door 303, the rotating shaft 503 will be pulled to rotate, causing the torsion spring 504 to begin accumulating elastic potential energy. A limit rod 506 is installed on one side of the rotating shaft 503. During the rotation of the rotating shaft 503, the limit rod 506 will rotate along with it until it passes the movable plate 508. 508 is connected to the fixed part 502 by a rotating rod 507, and a spring is provided between the movable plate 508 and the limiting plate 509. Therefore, after the limiting rod 506 passes the movable plate 508, the movable plate 508 will quickly return to its original position and fit tightly against the limiting plate 509. Therefore, when the protective door 303 is opened, when the torsion spring 504 releases its elastic potential energy, it will cause the rotating shaft 503 to return to its original position. However, after the limiting rod 506 passes the movable plate 508, when the rotating shaft 503 returns to its original position, the limiting rod 506 will be blocked by the movable plate 508, so that the rotating shaft 503 cannot return to its original position. Therefore, the elastic potential energy of the torsion spring 504 will not be fully released, thus ensuring that the protective door 303 will not close.

[0039] In the example, the clamping mechanism 6 includes a clamping plate 601, a first inclined block 602, a second inclined block 603, a telescopic block 604, a sliding block 605, a driving block 606, and a movable groove 607. The clamping plate 601 is movably installed on the bottom of the inner side of the movable shell 302. The first inclined block 602 is fixedly installed on one end of the inner side of the fixed shell 301. The second inclined block 603 is fixedly installed on the other end of the inner side of the fixed shell 301. The telescopic block 604 is fixedly installed on the bottom of one side of the clamping plate 601. One side of the telescopic block 604 is movably connected to the sliding block 605. The top of the sliding block 605 is fixedly connected to the driving block 606. The driving block 606 is slidably connected to the movable shell 302 through the movable groove 607. The sliding block 605 has inclined surfaces at both ends, and the inclined surfaces at both ends of the sliding block 605 respectively cooperate with the inclined surfaces of the first inclined block 602 and the second inclined block 603.

[0040] One side of the sliding block 605's inclined surface contacts the inclined surface of the second inclined block 603. The sliding block 605 then passively moves along the inclined surface of the second inclined block 603, thereby driving the clamping plate 601 towards the book via the telescopic block 604. Opposite to the clamping plate 601 inside the movable housing 302, an elastic block is installed. Therefore, the clamping plate 601 pushes the book towards the elastic block, thus clamping the book and preventing it from tipping over inside the movable housing 302, avoiding damage. The clamping plate 601 and the sliding block 605 are connected by the telescopic block 604. 4. Connection: When the book has a large thickness, the clamping plate 601 will squeeze the book under the action of the sliding block 605, while the other side of the book will contact the elastic block until the book is clamped and fixed. At this time, the sliding block 605 continues to move, which will cause the clamping plate 601 to squeeze the telescopic block 604 in the opposite direction. An elastic mechanism is installed inside the telescopic block 604, which can realize the elastic connection between the clamping plate 601 and the sliding block 605. Therefore, under the action of the telescopic block 604, the clamping plate 601 will shorten the distance between itself and the sliding block 605, thereby realizing the adaptive adaptation of the clamping mechanism 6 to the thickness of the book.

[0041] In the example, the door opening mechanism 4 includes a fixed plate 401, a U-shaped ring 402, a magnetic repulsion block 403, a second electromagnetic lock 404, and an electromagnet 405. The fixed plate 401 is fixedly installed at one end of the movable shell 302, the U-shaped ring 402 is fixedly installed on the top of the outer wall of the fixed plate 401, the magnetic repulsion block 403 is fixedly installed on one side of the fixed plate 401, the second electromagnetic lock 404 is fixedly installed inside the placement shell 201, and the second electromagnetic lock 404 plays the role of locking the U-shaped ring 402. The electromagnet 405 is fixedly installed inside the placement shell 201, and the magnetic field of the electromagnet 405 when energized is repulsive to the magnetic field of the magnetic repulsion block 403.

[0042] The door opening mechanism 4 is installed on the back of the protection mechanism 3. The second electromagnetic lock 404 installed on the placement shell 201 will receive an electrical signal and be energized and closed in a short time, thereby releasing the restriction on the U-shaped ring 402. At the same time, the electromagnet 405 installed on the placement shell 201 will also be energized in a short time. At this time, the electromagnet 405 will generate a magnetic field. The magnetic repulsion block 403 is installed on the back of the movable shell 302 through the fixing plate 401. The magnetic repulsion block 403 itself always has magnetism, and its magnetic field is repulsive to the magnetic field generated by the energized electromagnet 405.

[0043] In the example, the protection mechanism 3 also includes a handle 304 and a first electromagnetic lock 305. The handle 304 is fixedly installed on one side of the movable housing 302, and the first electromagnetic lock 305 is fixedly installed on one end of the inner side of the movable housing 302. The first electromagnetic lock 305 serves to restrict the protective door 303. The protection mechanism 3 also includes a pulley 306 and a slide rail 307. The pulley 306 is movably installed at the bottom of the movable housing 302, and the slide rail 307 is opened inside the fixed housing 301. The pulley 306 and the slide rail 307 are movably connected.

[0044] The push plate 510 is installed on the top of the movable plate 508. When the push plate 510 is pushed, the movable plate 508 will rotate around the rotating rod 507, which will release the restriction of the limit rod 506. The torsion spring 504 will completely release its elastic potential energy, so that the rotating shaft 503 and the limit rod 506 will be reset. The rotating shaft 503 will then wind up the pull rope 505, thereby pulling the protective door 303 and closing the protective door 303. The first electromagnetic lock 305 will lock the protective door 303, thus completing the automatic closing of the protective door 303. This prevents users from forgetting to close the protective door 303 when returning books, and also prevents external dust from contaminating the books.

[0045] In the example, the placement mechanism 2 also includes a ventilation pipe 202 and an air vent 203. The ventilation pipe 202 is fixedly installed on one side of the placement shell 201 and is connected to an external fan. The air vent 203 is located at the bottom of one side of the movable shell 302 and serves to connect the inside and outside of the movable shell 302. The books are fixed inside the protective mechanism 3 and will not be affected by external factors, so they will not fall off the bookshelf. The air vent 203 is located on the bottom back of the movable shell 302, and the ventilation pipe 202 is also located horizontally on one side of the placement shell 201. The ventilation pipe 202 is connected to an external fan duct. When the books are protected, the fan will work continuously to circulate air inside the protective mechanism 3 through the ventilation pipe 202, preventing the books from getting damp and reducing their lifespan.

[0046] The working principle of this invention is as follows: When in use, the power is turned on and an intelligent book borrowing system is installed on one side of the bookshelf body 1. When borrowing books, users can borrow books through the intelligent panel. Inside the bookshelf body 1, multiple sets of placement mechanisms 2 are placed. Inside each set of placement mechanisms 2, multiple sets of protective mechanisms 3 are installed by bolts. Inside each set of protective mechanisms 3, the protected books are placed.

[0047] After the user selects a book through the smart panel, the book borrowing system can send electrical signals to the protection mechanism 3 and the opening mechanism 4. The opening mechanism 4 is installed on the back of the protection mechanism 3. The second electromagnetic lock 404 installed on the placement shell 201 will receive the electrical signal and be energized and closed for a short time, thereby releasing the restriction on the U-shaped ring 402. At the same time, the electromagnet 405 installed on the placement shell 201 will also be energized for a short time. At this time, the electromagnet 405 will generate a magnetic field. The magnetic repulsion block 403 is installed on the back of the movable shell 302 through the fixing plate 401. The magnetic repulsion block 403 itself always has magnetism, and its magnetic field is repulsive to the magnetic field generated by the energized electromagnet 405.

[0048] Therefore, under the magnetic action of the electromagnet 405, the magnetic repulsion block 403 will drive the movable shell 302 to move in the opposite direction to the location of the electromagnet 405. At the same time that the second electromagnetic lock 404 receives the electrical signal, the first electromagnetic lock 305 will also receive the electrical signal. After being energized for a short time, the first electromagnetic lock 305 will close, releasing the restriction on the protective door 303. Therefore, when the movable shell 302 moves, it will cause the protective door 303 to open passively.

[0049] A pull rope 505 is installed on the bottom inner side of the protective door 303. When the protective door 303 is passively opened, the pull rope 505 will be pulled. The other end of the pull rope 505 is fixed to the rotating shaft 503. A torsion spring 504 is installed on the top of the rotating shaft 503. The torsion spring 504 is installed in the fixing part 502. Therefore, after the pull rope 505 is pulled by the protective door 303, the rotating shaft 503 will be pulled to rotate by the pull rope 505, which will cause the torsion spring 504 to start accumulating elastic potential energy.

[0050] A limiting rod 506 is installed on one side of the rotating shaft 503. During the rotation of the rotating shaft 503, the limiting rod 506 will rotate along with it until the limiting rod 506 passes the movable plate 508. The movable plate 508 is connected to the fixed part 502 through the rotating rod 507. A spring is set between the movable plate 508 and the limiting plate 509. Therefore, after the limiting rod 506 passes the movable plate 508, the movable plate 508 will quickly return to its original position and fit tightly against the limiting plate 509.

[0051] Therefore, when the protective door 303 is opened, when the torsion spring 504 releases its elastic potential energy, it will cause the rotating shaft 503 to reset. However, after the limit rod 506 passes through the movable plate 508, when the rotating shaft 503 resets and rotates, the limit rod 506 will be blocked by the movable plate 508, so that the rotating shaft 503 cannot reset. Therefore, the elastic potential energy of the torsion spring 504 will not be fully released, thus ensuring that the protective door 303 will not close.

[0052] As the movable shell 302 moves out of the fixed shell 301, the clamping mechanism 6 inside the movable shell 302 will also open simultaneously. The sliding block 605 installed on one side of the clamping plate 601 will contact the first inclined block 602, and then the inclined surface on one side of the sliding block 605 will move along the inclined surface of the first inclined block 602, thereby passively causing the driving block 606 to move inside the movable groove 607, thereby releasing the clamping plate 601 from restricting the book.

[0053] After the movable shell 302 moves out of the fixed shell 301, the user can easily take out the book from the movable shell 302, and then push the movable shell 302 into the fixed shell 301 through the handle 304, and then the protective door 303 is automatically closed by the closing mechanism 5.

[0054] When returning books, after the user moves the movable shell 302 out of the fixed shell 301 through the intelligent book lending system, the user places the book inside the movable shell 302 and then pushes the movable shell 302 towards the fixed shell 301 through the handle 304.

[0055] At this time, the clamping mechanism 6 inside the movable shell 302 will passively start working. The inclined surface of one side of the sliding block 605 will contact the inclined surface of the second inclined block 603. Then the sliding block 605 will passively move along the inclined surface of the second inclined block 603, thereby driving the clamping plate 601 to move towards the book through the telescopic block 604. On the opposite side of the clamping plate 601 inside the movable shell 302, an elastic block is installed. Therefore, the clamping plate 601 will push the book towards the direction of the elastic block, thereby completing the clamping of the book and preventing the book from tipping over inside the movable shell 302, thus avoiding damage to the book.

[0056] The clamping plate 601 and the sliding block 605 are connected by the telescopic block 604. When the book has a large thickness, the clamping plate 601 will squeeze the book under the action of the sliding block 605, and the other side of the book will contact the elastic block until the book is clamped and fixed. At this time, the sliding block 605 continues to move, which will cause the clamping plate 601 to squeeze the telescopic block 604 in the opposite direction. An elastic mechanism is installed inside the telescopic block 604, which can realize the elastic connection between the clamping plate 601 and the sliding block 605. Therefore, under the action of the telescopic block 604, the clamping plate 601 will shorten the distance between itself and the sliding block 605, thereby realizing the adaptive function of the clamping mechanism 6 to the thickness of the book.

[0057] After the movable shell 302 is pushed into the fixed shell 301, the U-shaped ring 402 will first get into the second electromagnetic lock 404, and then the movable shell 302 will continue to move by the handle 304. At this time, the push rod 511 installed on the back of the movable shell 302 will contact the push plate 510. When the movable shell 302 is pushed a short distance, the push rod 511 will push the push plate 510.

[0058] The push plate 510 is installed on the top of the movable plate 508. When the push plate 510 is pushed, the movable plate 508 will rotate around the rotating rod 507, which will release the restriction of the limit rod 506. The torsion spring 504 will completely release its elastic potential energy, so that the rotating shaft 503 and the limit rod 506 will be reset. The rotating shaft 503 will then wind up the pull rope 505, thereby pulling the protective door 303 and closing the protective door 303. The first electromagnetic lock 305 will lock the protective door 303, thus completing the automatic closing of the protective door 303. This prevents users from forgetting to close the protective door 303 when returning books, and also prevents external dust from contaminating the books.

[0059] The books are fixed inside the protective mechanism 3 and will not be affected by external factors, so they will not fall off the bookshelf. A vent 203 is opened on the bottom back of the movable shell 302, and a ventilation pipe 202 is opened at the same horizontal position on the side where the shell 201 is placed. The ventilation pipe 202 is connected to the external fan duct. When the books are protected, the fan will work continuously to circulate the air inside the protective mechanism 3 through the ventilation pipe 202, preventing the books from getting damp and reducing their lifespan.

[0060] The above structure can solve the technical problem that when readers borrow and return books, books placed together may fall off the bookshelf body 1, and dust will fall on the books and make them dirty if left for a long time.
