Description

Technical Field

[0001] The present application relates to the technical field of library management, and in particular to a book lending and returning device. Background Art

[0002] With the rapid development of information technology, libraries, as holy places for knowledge dissemination and academic research, are also continuously innovating and upgrading their management and service methods. The traditional way of borrowing and returning books often relies on cumbersome manual operations and paper records, which is not only inefficient, but also has many hidden dangers in terms of accuracy, timeliness and security. Therefore, an efficient, convenient and intelligent book borrowing and returning device came into being to meet the urgent needs of modern library management.

[0003] At present, there are some advanced book borrowing and returning devices on the market, which can effectively replace the traditional manual borrowing mode. For example, a split book borrowing and returning device (patent publication number: CN217606411U) realizes automatic recognition and interaction of book information through the clever design of the bracket group, table group and display function group. The built-in sensing device and RFID antenna of the table group can quickly read the book information; while the display function group integrates functions such as touch screen display, voice module, scanning device, face recognition device, card swiping device and printer, providing users with a rich and diverse interaction mode. This device undoubtedly greatly improves the efficiency of book borrowing and returning, reduces the workload of administrators, and lays a solid foundation for the intelligent management of libraries. However, after in-depth research and actual use feedback, we found that these devices still have some shortcomings. The most prominent problem is that the height of its working platform is fixed and cannot adapt to users of different statures. For users with shorter stature, this fixed height working platform is obviously not user-friendly enough. They may find it difficult to touch the operation interface of the device during operation, and even need to tiptoe or find auxiliary tools to complete the book borrowing and returning process. This not only increases the difficulty and inconvenience of their use, but also affects the smoothness and efficiency of the entire borrowing and returning process. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0021] Example:

[0022] See also Figure 1 , Figure 2 , Figure 3 A book lending and returning device comprises a book lending and returning machine 1 and a lifting component 2 fixedly installed on the bottom side wall of the book lending and returning machine 1.

[0023] Among them, the book lending and returning machine 1 is the core equipment of modern libraries, and its design and functions are highly intelligent; the main part of the book lending and returning machine 1 is made of sturdy and durable metal material, and the surface is sprayed with an environmentally friendly coating that is anti-fingerprint and anti-scratch, which is both beautiful and durable; the device is equipped with a large-size touch screen operation interface, the interface design is simple and clear, and the icons and texts are clear and easy to read, so that users can quickly get started; during the operation process, first select the borrowing or returning function through the touch screen. For the borrowing operation, the user places the book in the sensing area, enters personal information or scans the borrowing card, and after confirming that the book information is correct, clicks to confirm the borrowing. For the returning operation, the user puts the book to be returned into the return port, the device automatically identifies the book information and prompts the successful return or payment of the fine. After the operation is completed, the device will print out a borrowing voucher or a returning voucher, and the user can leave the library with this voucher; and the book lending and returning machine 1 adopts the existing technology in this field, so it will not be described in detail.

[0024] Among them, the lifting component 2 installed on the bottom side wall of the book lending and returning machine 1 fully considers the needs of borrowers with shorter stature, ensuring that they can also easily reach the operating platform in the book lending and returning machine 1, so as to enjoy a more convenient and barrier-free borrowing experience; this design fully reflects the humanized care and practicality of the equipment, and provides more intimate and efficient services for different user groups.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A book lending and returning device includes a lifting component 2, and the lifting component 2 is composed of a base mechanism 21, a lifting mechanism 22, a connecting mechanism 23 and a load-bearing mechanism 24, wherein the base mechanism 21 includes a base 211, a frame 212, two partitions 213 and a through hole 214; the lifting mechanism 22 includes two double-headed motors 221, four connecting plates 222, four fixing plates 223, four limit blocks 224, four guide rods 225 and four elliptical blocks 226; the connecting mechanism 23 includes a telescopic cylinder 231 and two flanges 232; the load-bearing mechanism 24 includes a load-bearing plate 241 and an anti-slip pad 242.

[0026] Among them, the base mechanism 21 serves as a stable foundation for the entire lifting component. The base 211, as the core part of the base mechanism 21, is made of high-strength steel and has excellent load-bearing capacity and stability. Its surface is anti-slip treated to ensure that the connection with the bottom end of the book lending and returning machine 1 is firm and reliable and not easy to loosen; one end of the base 211 is fixedly connected to the bottom end of the book lending and returning machine 1 by bolts or welding to ensure that the entire lifting component 2 and the book lending and returning machine 1 form a stable whole, and the other end is provided with a frame 212, which is welded with high-quality steel and can withstand the impact and vibration of the load-bearing mechanism 24 during the lifting process; inside the frame 212, we install The lifting mechanism 22 and the connecting mechanism 23 are connected to make the structure compact, reduce the space occupied, and ensure the beauty of the entire equipment; in addition, the side wall of the frame 212 is also provided with a through hole 214, which is convenient for the wiring layout during installation and debugging, effectively reduces the heat generated by the lifting component 2 during operation, and extends the service life of the equipment; two partitions 213 are respectively fixed at the two ends of the interior of the frame 212. Their main function is to strengthen the structural strength of the frame and prevent the load-bearing mechanism 24 from deformation or twisting during the lifting process. At the same time, the partition 213 can also divide the internal space of the frame 212 into multiple areas, which is convenient for the layout and installation of the lifting mechanism 22.

[0027] Among them, in the design of the base mechanism 21, the base 211, the frame 212 and the two partitions 213 are molded by integral casting, so that the entire base mechanism 21 becomes a more solid and stable whole; this one-piece molding process ensures that the connection between the various components is tight and seamless, and effectively avoids loosening or deformation caused by long-term use or external force; at the same time, the one-piece molding structure also reduces maintenance problems caused by loose or damaged connectors, reducing maintenance costs and difficulty.

[0028] The lifting mechanism 22 is exquisitely designed and powerful to achieve the smooth lifting of the load-bearing mechanism 24; the double-headed motor 221 is used as the power source of the lifting mechanism, and its two ends are firmly connected to the connecting plate 222 by bolts to ensure that there is no relative displacement between the double-headed motor 221 and the connecting plate 222. The output end of the double-headed motor 221 passes through the side wall of the connecting plate 222 and is connected to one end of the guide rod 225 by a coupling, so that the guide rod 225 can be driven to rotate; the connecting plate 222 serves as the double-headed motor 221 and the fixed plate 22 3, and its separated end is bolted to the opposite end of the fixing plate 223, so that the entire lifting mechanism 22 can be firmly installed on the base mechanism 21; the bottom of the fixing plate 223 is in contact with the surface of the base 211, and the limit block 224 and the fixing plate 223 are fixed to the surface of the base 211 by bolts, ensuring the stability of the lifting mechanism 22 during the lifting and lowering of the load-bearing mechanism 24; the internal bearing of the limit block 224 is connected to the outer wall of the guide rod 225, so that the guide rod 225 can rotate smoothly under the drive of the motor , the other end of the guide rod 225 is fixedly connected to one end of the side wall of the elliptical block 226. The design of the elliptical block 226 enables the load-bearing mechanism 24 to better contact and apply force to the load-bearing plate 241 during the lifting process; the elliptical block 226 is installed between the frame 212 and the two partitions 213, and the space between the partitions 213 and the frame 212 can be used to protect the elliptical block 226. When the double-headed motor 221 is started, the elliptical block 226 will rotate through the transmission of the guide rod 225, thereby lifting the load-bearing mechanism 24; this design enables the load-bearing mechanism 24 to be lifted and lowered smoothly, providing users with a comfortable and safe operating experience; in addition, the user installs a controller on the side wall of the book lending and returning machine 1, and is electrically connected to the double-headed motor 221 and the internal power supply of the book lending and returning machine 1. Through a precise control algorithm, the double-headed motor 221 can be accurately controlled, thereby realizing precise adjustment of the lifting speed and height of the load-bearing mechanism 24, which not only improves the convenience of operation of the equipment, but also provides users with a more personalized service experience.

[0029] The connecting mechanism 23 is a key component in the lifting component 2, and is mainly used to connect the base mechanism 21 and the load-bearing mechanism 24 to ensure the stability and flexibility between them. The telescopic cylinder 231 is made of a material with high strength and certain elasticity, and the two ends of its outer wall are respectively welded to the inner circles of the two flanges 232. This welding method not only ensures the connection strength between the telescopic cylinder 231 and the flange 232, but also enables the entire connecting mechanism 23 to maintain the stability of the load-bearing plate 241 when it is subjected to tension and compression during the lifting process. The two flanges 23 2 are used to connect with the base mechanism 21 and the load-bearing mechanism 24 respectively. The outer wall of the flange 232 is designed with bolt holes, which are convenient for bolting with the surface of the base 211 and the bottom of the load-bearing plate 241. This connection method is simple and firm, and can effectively fix the connecting mechanism 23 at the appropriate position of the lifting component 2; during the lifting process of the load-bearing mechanism 24, the telescopic cylinder 231 can be extended and retracted as needed to adapt to the adjustment requirements of different heights of the load-bearing plate 241; at the same time, the firm connection of the flange 232 ensures the stability and safety of the entire lifting component.

[0030] Among them, the load-bearing mechanism 24 is an important component that carries the user and rises and falls with the user; the load-bearing plate 241, as the main part that carries the user, is made of high-strength and wear-resistant materials to ensure that it can withstand heavy weight and frequent stepping; its bottom is connected to the outer wall of the flange 232 in the connecting mechanism 23 by bolts, and this connection method is both firm and easy to disassemble and maintain; the anti-skid pad 242 is adhered to the surface of the load-bearing plate 241 and is made of rubber with a high friction coefficient to effectively prevent the user from slipping when operating the book lending and returning machine 1; the bottom of the anti-skid pad 242 is connected to the surface of the load-bearing plate 241 by gluing, and this connection method is simple and firm, which can ensure that the anti-skid pad is not easy to fall off during use; in addition, the design of the load-bearing mechanism 24 also takes into account the comfort and convenience of the user. The surface of the load-bearing plate 241 adopts an anti-skid texture design, and cooperates with the anti-skid pad 242, which not only increases the friction, but also enhances the user's tactile experience. At the same time, the edge of the load-bearing plate 241 is also rounded to prevent the user from getting injured when stepping on it.

[0031] The working principle of the book borrowing and returning device is as follows: when the borrowing user is ready to use the device, the borrowing user first steps on the anti-slip mat 242 to ensure the stability and safety of the operation. Then, the user starts the double-headed motor 221 through the controller, and the double-headed motor 221 immediately drives the guide rod 225 to rotate. The rotation of the guide rod 225 further drives the elliptical block 226 to rotate, thereby lifting the load plate 241; during the entire lifting process, the user can accurately adjust the lifting speed and height of the load-bearing mechanism 24 through the controller. This design takes into account the needs of users of different heights and provides them with a comfortable and safe operating experience; whether it is a tall user or a short user, they can easily find an operating height that suits them; when the load plate 241 is raised to a suitable position, the user can use the book borrowing and returning machine 1 to borrow and return books. The entire process is efficient and convenient, which not only saves the user's time, but also improves the service efficiency of the library.

[0032] It should be noted that the specific models and specifications of the telescopic cylinder 231, the double-headed motor 221, and the elliptical block 226 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and principle of the double-headed motor 221 are clear to those skilled in the art and will not be described in detail here.

[0034] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
