Description

Technical Field

[0001] This utility model relates to the field of library equipment technology, specifically to a self-service library book borrowing and returning anti-theft device. Background Technology

[0002] Self-service book borrowing and returning is an important aspect of modern library services. With the help of intelligent equipment, readers can independently complete the borrowing and returning process. It breaks the traditional time constraints of borrowing and returning books, allowing readers to flexibly arrange their time, improving library service efficiency, and providing readers with a convenient and independent borrowing experience, thus embodying innovation in library service models.

[0003] Utility model patent CN219105554U discloses a convenient and fast self-service library book return device. This device includes a self-service return machine, a return slot, and a barcode scanner. The return slot is located at the bottom of the front of the self-service return machine. By using a scraper, the user moves the book to the left, pressing the scraper against the spine. This scraping removes dust or other stains adhering to the spine. The spine then moves to the top of an absorbent sponge, which absorbs and dries the cleaning solution. This solution addresses the problem that books, due to frequent use and handling, easily accumulate dust and dirt, making it difficult for barcode scanners to read and thus affecting the efficiency of self-service library book return devices. It effectively cleans stains from the barcode area.

[0004] This convenient and fast self-service library book return device lacks a structure to prevent unauthorized removal of books during the handover process. Once a book is placed in the return slot, there is no effective sealing protection before the device completes the acceptance confirmation. This poses a risk that the book may be taken away again, causing the device to misjudge the return status and making the book easy to be stolen. In view of this, we propose a self-service library book borrowing and returning anti-theft device. Utility Model Content

[0005] The purpose of this invention is to provide a self-service library book borrowing and returning anti-theft device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A library self-service borrowing and returning anti-theft device includes a self-service borrowing machine. An anti-theft mechanism is installed at the book entrance / exit of the front of the self-service borrowing machine. The anti-theft mechanism includes a base fixed to the front of the self-service borrowing machine, a conveying assembly installed in the base for conveying books, and a closing assembly covering the top of the base and capable of opening and closing. The top of the base has a cavity, and the rear end of the cavity is connected to the book entrance / exit of the self-service borrowing machine. The conveying assembly includes several rotating columns rotatably connected to the bottom of the cavity and a conveying motor. The conveying motor is coaxially connected to one of the rotating columns, and the rotating columns are connected to each other by a toothed belt. The closing assembly includes a cover plate hinged to the rear side of the top of the base and an opening / closing motor. A fixing rod is coaxially connected to the rear end of the cover plate, and a lever is coaxially connected to the end of the output shaft of the opening / closing motor. The lever can move the fixing rod to drive the cover plate to open and close on the base.

[0007] Preferably, the top of the pedestal has a groove, the cover plate overlaps the groove, and the rear end of the cover plate is hinged to the rear end of the groove. In this design, the groove provides overlap limit for the cover plate, enhancing stability and sealing when closed and reducing external interference.

[0008] Preferably, the rotating column is parallel to the length direction of the base, and a gear is coaxially connected to the right end of the rotating column. The gear is sleeved inside the toothed belt and meshes with the toothed belt. In this setup, the gears and belt work together to make the rotating column rotate synchronously, ensuring smooth book transport and preventing deviation or jamming.

[0009] Preferably, a first baffle is fixed on the right end face of the platform, and a fixing plate is fixed inside the first baffle. The fixing plate is parallel to the right end face of the platform, and the conveying motor is mounted on the right end face of the fixing plate. In this setup, the first baffle protects the internal transmission components, and the fixing plate enhances the installation stability of the conveyor motor.

[0010] Preferably, the first end of the fixing rod is coaxially fixedly connected to the rear end of the cover plate, and a T-shaped hanging rod is coaxially fixedly connected to the left end face of the end of the fixing rod. The first end of the lever is coaxially connected to the end of the output shaft of the start-stop motor. A waist-shaped groove is opened on the outer surface of the end of the lever, and the hanging rod is hung in the waist-shaped groove. In this design, the connection structure between the hanging rod and the waist-shaped groove allows the rotation of the lever to be smoothly converted into the opening and closing action of the cover plate.

[0011] Preferably, a second baffle is fixed on the left end face of the platform, and a mounting plate is fixed inside the second baffle. The mounting plate is parallel to the left end face of the platform, and the opening and closing motor is mounted on the left end face of the mounting plate. In this setup, the second shield protects the internal components, and the mounting plate provides a stable mounting base for the start-stop motor, facilitating centralized maintenance of the components.

[0012] Preferably, a first stop post is fixed on the right end face of the mounting plate. When the start-stop motor drives the lever to rotate and touches the first stop post, the cover plate covers the top of the pedestal. In this setup, the first stop precisely limits the rotation angle of the lever, ensuring that the cover plate closes completely and forms an effective seal.

[0013] Preferably, a second stop post is also fixed on the right end face of the mounting plate, and the lever is clamped between the first stop post and the second stop post. When the opening and closing motor drives the lever to rotate and touches the second stop post, the cover plate is in the open state. In this configuration, the second stop bar works in conjunction with the first stop bar to limit the rotation range of the lever, preventing the cover plate from being damaged due to excessive rotation.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The library's self-service borrowing and returning anti-theft device uses an anti-theft mechanism installed at the book entrance and exit of the self-service borrowing machine. Books are placed in the recess of the base, and after a person's hands leave, the cover of the sealing component closes in time to form a closed space. Then, the conveying component transports the book into the self-service borrowing machine. This structural design can provide effective closed protection after the book is placed and before the machine completes the receiving process, preventing the book from being taken away without authorization and achieving the purpose of anti-theft.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 The library's self-service borrowing and returning anti-theft device includes a self-service borrowing machine 100. An anti-theft mechanism 200 is located at the book entry / exit point at the front of the self-service borrowing machine 100. The anti-theft mechanism 200 includes a base 210 fixed to the front of the self-service borrowing machine 100, a conveying component 220 installed inside the base 210 for transporting books, and a closing component 230 covering the top of the base 210 and capable of opening and closing. The base 210 is made of high-strength ABS plastic, possessing good load-bearing capacity and wear resistance, providing stable support for the entire anti-theft mechanism 200. The conveying component 220 enables the orderly transfer of books between the base 210 and the self-service borrowing machine 100, while the closing component 230 provides protection through its opening and closing action, preventing unauthorized removal of books during the handover process.

[0018] like Figures 2-4As shown in the present invention, the top of the base 210 is provided with a cavity 211, and the rear end of the cavity 211 is connected to the book inlet and outlet of the self-service borrowing machine 100. The size of the cavity 211 is adapted to common book specifications, providing a limiting space for the book and preventing the book from shifting when placed. The conveying assembly 220 includes several rotating columns 221 rotatably connected to the bottom of the cavity 211 and a conveying motor 222. The rotating columns 221 are made of stainless steel with a smooth surface to reduce friction damage to the book cover. The conveying motor 222 is coaxially connected to one of the rotating columns 221. The rotating column 221 is parallel to the length direction of the platform 210. A gear 2211 is coaxially connected to the right end of the rotating column 221. The gear 2211 is sleeved inside the toothed belt 223 and meshes with the toothed belt 223, so that the rotating columns 221 are connected to each other through the toothed belt 223. The cooperation between the gear 2211 and the toothed belt 223 ensures that the multiple rotating columns 221 rotate synchronously, ensuring that the force is even during book conveying and avoiding jamming.

[0019] like Figure 5 As shown, specifically, a first baffle 240 is fixed on the right end face of the base 210. The first baffle 240 is made of transparent acrylic material, which can protect the internal transmission components and facilitate the observation of the operating status of the gear 2211 and the toothed belt 223 by the staff. A fixing plate 241 is fixed inside the first baffle 240. The fixing plate 241 is made of cold-rolled steel plate, which improves the stability of the installation of the conveyor motor 222. The fixing plate 241 is parallel to the right end face of the base 210. The gear 2211 is located on the left side of the fixing plate 241. The conveyor motor 222 is installed on the right end face of the fixing plate 241. This installation method allows the motor output force to be directly transmitted to the rotating column 221, reducing power loss.

[0020] like Figure 2 and Figure 6 As shown, the sealing component 230 further includes a cover plate 231 hinged to the rear side of the top of the base 210 and an opening and closing motor 232. The cover plate 231 is made of lightweight alloy material, which ensures structural strength and reduces the load during opening and closing. The top of the base 210 has a groove 212, and the cover plate 231 overlaps in the groove 212. The rear end of the cover plate 231 is hinged to the rear end of the groove 212. The cooperation between the groove 212 and the cover plate 231 can enhance the sealing performance when closed and prevent external impurities from entering the cavity 211.

[0021] like Figure 6 and Figure 8As shown, in addition, a fixing rod 2311 is coaxially connected to the rear end of the cover plate 231, and a lever 2321 is coaxially connected to the end of the output shaft of the start / stop motor 232. Both the fixing rod 2311 and the lever 2321 are made of stainless steel and can withstand the force generated by repeated plucking. The lever 2321 can plucking the fixing rod 2311 to drive the cover plate 231 to open and close on the base 210. The first end of the fixed rod 2311 is coaxially fixedly connected to the rear end of the cover plate 231. A T-shaped hanging rod 2312 is coaxially fixedly connected to the left end face of the end of the fixed rod 2311. The first end of the lever 2321 is coaxially connected to the end of the output shaft of the start-stop motor 232. A waist-shaped groove 2322 is opened on the outer surface of the end of the lever 2321. The hanging rod 2312 is hung in the waist-shaped groove 2322. The hanging structure of the hanging rod 2312 and the waist-shaped groove 2322 enables the rotation of the lever 2321 to be smoothly converted into the opening and closing action of the cover plate 231, reducing mechanical wear.

[0022] like Figure 2 , Figure 7 and Figure 8 As shown, it is worth noting that a second baffle 250 is fixed on the left end face of the base 210. The second baffle 250 is made of the same material as the first baffle 240 and provides protection for internal components such as the fixing rod 2311 and the lever 2321. A mounting plate 251 is fixed inside the second baffle 250. The mounting plate 251 is made of the same material as the fixing plate 241 and provides a stable mounting base for the opening and closing motor 232. The mounting plate 251 is parallel to the left end face of the base 210. The opening and closing motor 232 is mounted on the left end face of the mounting plate 251. The fixing rod 2311 and the lever 2321 are both located on the right side of the mounting plate 251. This layout concentrates the transmission components of the enclosure assembly 230 in the same area, which is convenient for later maintenance.

[0023] like Figure 7 and Figure 8 As shown, it should be added that a first stop post 252 is fixed on the right end face of the mounting plate 251. When the start / stop motor 232 drives the lever 2321 to rotate and contact the first stop post 252, the cover plate 231 covers the top of the base 210. The first stop post 252 can precisely limit the rotation angle of the lever 2321, ensuring that the cover plate 231 is closed in place. A second stop post 253 is also fixed on the right end face of the mounting plate 251. Both the first stop post 252 and the second stop post 253 are made of brass, which has good wear resistance and can extend service life. The lever 2321 is clamped between the first stop post 252 and the second stop post 253. When the start / stop motor 232 drives the lever 2321 to rotate and contact the second stop post 253, the cover plate 231 is in the open state. The second stop post 253 cooperates with the first stop post 252 to prevent the lever 2321 from rotating too much and damaging the cover plate 231.

[0024] It is worth noting that the conveyor motor 222 and the start-stop motor 232 involved in this utility model are both existing conventional technologies, and will not be described in detail in this utility model.

[0025] In this embodiment of the library self-service borrowing and returning anti-theft device, when in use, firstly, when the user returns a book, the opening and closing motor 232 drives the lever 2321 to rotate until it contacts the second stop 253, and the cover 231 is in the open state. The user places the book into the cavity 211 of the base 210. Then, after the user's hand leaves the cavity 211, the opening and closing motor 232 drives the lever 2321 to rotate in the opposite direction. Through the cooperation of the hanging rod 2312 and the waist-shaped groove 2322, the fixing rod 2311 is rotated, so that the cover 231 closes in the groove 212. When the lever 2321 contacts the first stop post 252, a closed space is formed. Then, the conveyor motor 222 starts, and through the transmission of gear 2211 and toothed belt 223, it drives multiple rotating columns 221 to rotate synchronously, conveying the books in the cavity 211 to the book entrance and exit of the self-service borrowing machine 100. Finally, after the books are returned to the self-service borrowing machine 100, the start-stop motor 232 drives the lever 2321 to rotate again, causing the cover 231 to reopen, waiting for the next operation. During the book return process, the user is separated from the books, achieving the effect of anti-theft.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
