Description

Technical Field

[0001] This utility model belongs to the field of library management technology, specifically relating to an archive and book inventory device. Background Technology

[0002] Traditional manual inventory checks of archives and books in libraries have significant limitations. Staff must verify each item, layer, and column of the collection, a process that is not only cumbersome and time-consuming but also prone to errors and omissions due to human negligence, making it difficult to guarantee the accuracy of the results. To address this issue, the industry now widely uses inventory counting devices to improve efficiency and data accuracy, meeting the actual needs of libraries for collection management.

[0003] As shown in patent CN208819231U, the disclosed inventory device mainly includes an omnidirectionally movable body and a vertically fixed column on top of the body. The body houses a processing unit that receives and processes inventory data and can also interact with a remote server for backup. Several data acquisition devices are spaced longitudinally along the column, and all data acquisition devices maintain a communication connection with the processing unit. In actual use, the device moves along a preset path via a bottom-mounted movable structure, simultaneously scanning the collection on multiple shelves using the longitudinally distributed data acquisition devices. This allows for the acquisition of inventory data from multiple shelf layers at once, reducing the need for repeated scanning.

[0004] However, in practice, libraries typically have load-bearing columns, and to make full use of space, bookshelves are often placed against these columns, creating narrow gaps between them. Because existing inventory devices are too large to fit into these narrow gaps, files or books within these gaps may fall outside the scanning range, creating blind spots in the inventory process. Ultimately, manual inventory checks are still necessary to fill these gaps, posing a risk of omissions. Utility Model Content

[0005] This invention addresses the problem that existing inventory devices cannot inventory archives and books within the narrow gap between the load-bearing column and the bookshelf, resulting in blind spots. It provides an archive and book inventory device that can inventory archives and books within the narrow gap between the load-bearing column and the bookshelf, thereby eliminating blind spots.

[0006] To solve the above problems, the technical solution adopted by this utility model is an archive and book inventory device, including an inventory cart with casters installed at the bottom. At least one set of rotating components is provided on the side of the inventory cart. Each set of rotating components includes a first connecting seat, a rotating rod, and a second connecting seat. The first connecting seat is fixedly connected to the side of the inventory cart. One end of the rotating rod is rotatably connected to the first connecting seat, and the other end of the rotating rod is rotatably connected to the second connecting seat. All the second connecting seats are fixedly connected to a support rod. A scanning component is installed on the support rod. The scanning component is electrically connected to the inventory cart and can scan archives or books on the bookshelf.

[0007] In this technical solution, the side of the inventory cart is equipped with at least one set of rotating components. Each set of rotating components includes a first connecting seat, a rotating rod, and a second connecting seat. The first connecting seat is fixedly connected to the side of the inventory cart. One end of the rotating rod is hinged to the first connecting seat, and the other end is hinged to the second connecting seat. All second connecting seats are fixedly connected to a support rod as a single unit. The support rod is equipped with a scanning component, which can scan the files or books on the bookshelf. When it is necessary to inventory files and books in the narrow gap between the support column and the bookshelf, the extension direction of the support rod can be adjusted by rotating the rotating rod, allowing the inventory cart to enter the gap without needing to enter the gap, and the scanning component can extend into the gap to complete the inventory operation. Therefore, this device can effectively inventory files and books in the narrow gap between the support column and the bookshelf, thereby eliminating blind spots in the inventory process.

[0008] Furthermore, the inventory cart includes a shell, a first fixed seat fixed to the side of the shell, a box attached to the shell, and a second fixed seat fixed to the side of the box. The second fixed seat is located below the first fixed seat, and the second fixed seat and the first fixed seat are distributed vertically. On the one hand, the box can directly store the files, books to be inventoried, or tools that need to be temporarily stored during the inventory process, avoiding the need for staff to carry extra storage containers, reducing hand burden during operation, and improving inventory efficiency. On the other hand, the vertical distribution of the first and second fixed seats, which jointly fix the support rod, can significantly improve the structural stability of the support rod. Compared with single-point fixation, the coordinated support of the upper and lower points can effectively limit the horizontal swaying and vertical offset of the support rod, ensuring that the support rod maintains a stable extension posture when adjusting the position of the scanning component, avoiding the scanning component from deviating from the target area due to the swaying of the support rod, thereby ensuring the accuracy of scanning files and books within the gap.

[0009] Furthermore, a positioning seat is fixed to the side of the housing, and a buckle is provided on the positioning seat. The buckle can lock and fix the rotating rod. When it is necessary to inventory the archives and books in the narrow gap between the support column and the bookshelf, after the rotating rod is rotated into place, the buckle can firmly fix the rotating rod, preventing the rotating rod from swinging randomly due to inertia or external force. This can prevent the rotating rod from colliding with the bookshelf, support column, etc. and causing deformation and damage, and can also prevent the swaying rotating rod from interfering with the balance of the inventory cart, ensuring stability during the movement.

[0010] Furthermore, there are two sets of rotating components, which are distributed vertically. The two sets of rotating components form a double-fulcrum support structure, which can effectively limit the horizontal swing and vertical torsional freedom of the support rod, so that the support rod maintains a stable spatial posture during rotation. Even if the scanning component generates an eccentric load due to its insertion into the gap, the two sets of rotating components can distribute the torque through coordinated force distribution, preventing the support rod from tilting or swaying laterally, and ensuring the smoothness of rotation adjustment.

[0011] Furthermore, there are several groups of scanning components, all of which are spaced apart along the length of the support rod. The spaced-out groups of scanning components can precisely correspond to each layer of the bookshelf, and a single adjustment can simultaneously complete the scanning of multiple layers of archives and books on the bookshelf, eliminating the need to move the scanning components layer by layer or adjust the height of the support rod. Especially for multi-layer mobile shelving, this can significantly reduce inventory time, greatly reduce repetitive operations, and improve overall inventory efficiency.

[0012] Furthermore, the scanning component includes a mounting plate, which internally houses a tag antenna and a QR code scanner. This enables full-coverage scanning of both tags, improving device compatibility. Currently, in archive and library management, some collections are tagged with RFID tags for rapid batch identification; others are tagged with QR code labels, which are low-cost and easy to manufacture. This design uses the tag antenna to scan RFID tags and the QR code scanner to scan QR code labels, simultaneously adapting to both mainstream tagging methods. It eliminates the need to replace scanning modules or carry multiple devices, meeting the inventory needs of different venues, such as libraries with existing RFID systems or small archives using only QR codes, avoiding limitations in equipment applicability caused by a single tag type.

[0013] Furthermore, a limiting groove plate is fixed to the side of the mounting plate near the support rod. The limiting groove plate snaps onto the support rod and can slide along it. A fastening screw is fixed to the bottom of the limiting groove plate. The support rod has an oblong hole that runs parallel to its length. The end of the fastening screw passes through the oblong hole and is screwed with a Torx nut. The limiting groove plate, through its snap-fit ​​structure, adheres to the support rod, which not only limits lateral displacement or torsion of the mounting plate during sliding but also ensures that the mounting plate always moves smoothly along the length of the support rod. The cooperation between the oblong hole, the fastening screw, and the Torx nut enables precise locking after adjustment. The oblong hole is set along the length of the support rod, providing sufficient adjustment stroke for the fastening screw, making it easy to move the mounting plate to the ideal position. After the position is determined, tightening the plum nut will firmly fix the limiting groove plate to the support rod through the clamping force between the screw and the nut. This prevents the mounting plate from shifting due to vibration, its own weight, or slight collisions during scanning, ensuring that the scanning component maintains a relatively fixed distance and angle from the archives and books throughout the entire inventory process, further guaranteeing the accuracy of the scanned data.

[0014] Furthermore, a connecting port is provided on the side of the mounting plate near the support rod, with the connecting port positioned opposite the oblong hole. This alignment allows the tag antenna and QR code scanner wires to pass sequentially through the connecting port and oblong hole into the support rod, preventing the wires from being exposed in the gap between the mounting plate and the support rod or to the external environment. This prevents the wires from being squeezed, worn, tangled, or jammed when the scanning assembly slides along the support rod, and also reduces damage to the wires from dust and impacts, lowering the risk of short circuits and poor contact, and ensuring the stability of power supply and data transmission for the scanning assembly.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] 1. Eliminates blind spots in inventory between load-bearing columns and bookshelves: By rotating the hinge structure of the first connecting seat, rotating rod, and second connecting seat in the assembly, the extension direction of the support rod can be adjusted, so that the inventory cart does not need to enter the narrow gap between the load-bearing column and the bookshelf, but only the scanning component can be inserted into the gap to achieve effective inventory of the archives and books in the gap.

[0017] 2. Ensure the effectiveness of scanning operations: All second connecting seats and support rods are fixed as one piece, which ensures that the support rods maintain a stable posture during rotation and adjustment, and avoids the scanning components from shifting due to structural loosening; at the same time, the scanning components on the support rods can directly scan the documents and books in the gaps without additional adjustment of the scanning angle, ensuring the accuracy of inventory data and the efficiency of scanning operations;

[0018] 3. Reduce the risk of collisions during operation: Since the inventory cart does not need to enter narrow gaps, it can complete the inventory simply by extending the scanning components through the rotating rod. This effectively avoids collisions between the inventory cart and load-bearing columns, bookshelves, or archives and books in the gaps. It protects the inventory cart and scanning components from damage and also prevents the archives and books from shifting or breaking due to collisions, thus ensuring the safety of the collection and the integrity of the equipment.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] An archival book inventory device includes an inventory cart 1, such as Figure 1 As shown, the bottom of the inventory cart 1 is equipped with casters 11, and at least one set of rotating components 2 is provided on the side of the inventory cart 1. All rotating components 2 are distributed vertically and are connected to the support rod 3. Scanning components 4 are installed on the support rod 3. There are several sets of scanning components 4. All scanning components 4 are distributed at intervals along the length of the support rod 3. All scanning components 4 are electrically connected to the inventory cart 1 through wires, and the scanning components 4 can scan the files or books on the bookshelf.

[0029] like Figure 2 As shown, in this specific embodiment, the inventory cart 1 includes a housing 12, which is hollow inside. The data processing and storage devices of the inventory unit are installed inside the housing 12, and all of these devices are existing equipment. There are four casters 11, which are evenly installed at the bottom of the housing 12. A touch screen all-in-one machine is embedded in the top of the housing 12, allowing staff to control the inventory unit and understand the inventory status through the touch screen all-in-one machine.

[0030] A first fixing seat 13 is fixed to the side of the housing 12. The first fixing seat 13 is positioned opposite to the support rod 3. That is, when the rotating assembly 2 rotates the support rod 3 to fit against the housing 12, the support rod 3 and the first fixing seat 13 are positioned opposite each other. A clamping plate is provided on the first fixing seat 13. When the support rod 3 is rotated to the position of the first fixing seat 13, the clamping plate can clamp the support rod 3, thereby limiting the horizontal movement of the support rod 3 and preventing it from swaying horizontally.

[0031] A box 14 is attached to the housing 12. The box 14 can directly store files and books to be inventoried. A second fixing seat 15 is fixed to the side of the box 14. The second fixing seat 15 is located below the first fixing seat 13, and the second fixing seat 15 and the first fixing seat 13 are distributed vertically. The second fixing seat 15 is also provided with a clamping plate. When the support rod 3 rotates to the position of the first fixing seat 13, the clamping plate on the second fixing seat 15 will also clamp the support rod 3, cooperating with the first fixing seat 13 to ensure that the support rod 3 will not wobble horizontally. The clamping plate of the second fixing seat 15 is provided with screw holes. After the clamping plate of the second fixing seat 15 clamps the support rod 3, a pressure plate is pressed onto the clamping plate of the second fixing seat 15 and fixed with bolts to fix the support rod 3 to the clamping plate of the second fixing seat 15.

[0032] A positioning seat 16 is also fixed to the side of the housing 12. A buckle 17 is provided on the positioning seat 16. The position of the buckle 17 is opposite to the position of one of the rotating components 2. The buckle 17 includes two horizontal plates arranged vertically. A strong magnet is fixedly installed inside the positioning seat 16. The position of the strong magnet corresponds to the buckle 17 and can attract the rotating component 2.

[0033] like Figure 3 As shown in this specific embodiment, there are two sets of rotating components 2, which are distributed vertically. Each set of rotating components 2 includes a first connecting seat 21, a rotating rod 22, and a second connecting seat 23, all of which are made of metal. The first connecting seat 21 is fixedly connected to the side of the inventory cart 1. One end of the rotating rod 22 is rotatably connected to the first connecting seat 21 via a pin. The rotating rod 22 is horizontally arranged. The other end of the rotating rod 22 is rotatably connected to the second connecting seat 23 via a pin. All the second connecting seats 23 are fixedly connected to the support rod 3 via bolts. The support rod 3 is arranged vertically.

[0034] like Figure 4-6 As shown, in this specific embodiment, the scanning component 4 includes a mounting plate 41. A tag antenna 42 and a QR code scanner 43 are installed inside the mounting plate 41. Both the tag antenna 42 and the QR code scanner 43 are existing devices. The tag antenna 42 can identify files or books affixed with RFID tags. RFID tags are electronic tags using Radio Frequency Identification (RFID) technology, capable of storing identification information of files or books and interacting with the tag antenna 42 via wireless signals. The QR code scanner 43 can identify files or books affixed with QR codes.

[0035] A limiting groove plate 44 is fixed to the side of the mounting plate 41 near the support rod 3. The limiting groove plate 44 has a U-shaped cross-section. The U-shaped groove of the limiting groove plate 44 is engaged with the support rod 3 and can slide along the support rod 3. A fastening screw 45 is fixed to the bottom of the limiting groove plate 44. The fastening screw 45 is perpendicular to the bottom of the limiting groove plate 44. A waist-shaped hole 31 is provided on the support rod 3. The waist-shaped hole 31 is in the same direction as the length of the support rod 3, and the position of the waist-shaped hole 31 corresponds to the fastening screw 45. The end of the fastening screw 45 passes through the waist-shaped hole 31 and is screwed with a plum nut 46.

[0036] The mounting plate 41 has a connecting port 47 on its side near the support rod 3, which is opposite to the oblong hole 31. The connecting port 47 is elongated to ensure that when the mounting plate 41 slides along the length of the support rod 3, the connecting port 47 always overlaps with the oblong hole 31. This ensures that the wires of the tag antenna 42 and the QR code scanner 43 pass through the connecting port 47 and the oblong hole 31 in sequence into the support rod 3, and finally exit from the bottom of the support rod 3 to make an electrical connection with the device inside the housing 12.

[0037] Working process: The support rod 3 is fixed on the second connecting seat 23. The two sets of second connecting seats 23 are rigidly connected to the support rod 3, which together constrain the spatial posture of the support rod 3 and ensure that it is always in a vertical state. Since the two ends of the rotating rod 22 are respectively hinged to the first connecting seat 21 and the second connecting seat 23 by pins, the support rod 3 can rotate around the first connecting seat 21 with the second connecting seat 23, so as to realize the flexible adjustment of the extension direction.

[0038] When conducting inventory checks in the regular bookshelf area, the operating procedure is as follows: First, rotate the support rod 3 to the position corresponding to the first fixed seat 13 and the second fixed seat 15. At this time, the clamping plate of the first fixed seat 13 clamps the support rod 3 from the top, and the clamping plate of the second fixed seat 15 clamps the support rod 3 from the bottom. The horizontal limit of the support rod 3 is achieved through the coordinated constraint of the upper and lower clamping plates. Then, the pressure plate is placed on the clamping plate of the second fixed seat 15, and the bolts are tightened through the screw holes on the pressure plate and the clamping plate to firmly fix the support rod 3 to the second fixed seat 15, ensuring that it does not shake during the inventory check. After fixing, the support rod 3 is attached to the side of the inventory cart 1. At this time, the position of the scanning component 4 needs to be adjusted according to the actual height of each shelf: loosen all the Phillips nuts 46 in sequence, push the mounting plate 41 to drive the limiting groove plate 44 to slide along the support rod 3, so that each set of mounting plates 41 is accurately aligned with the files or books on the corresponding shelf; after the position is calibrated, tighten the Phillips nuts 46 one by one, and fix the mounting plate 41 by the clamping force between the nuts and the limiting groove plate 44, so as to ensure the relative position of the scanning component 4 and the target shelf is stable. After completing the above adjustment, the staff starts the equipment through the touch screen all-in-one machine on the top of the housing 12, sets the inventory parameters, and then pushes the inventory cart 1 to move smoothly along the bookshelf through the bottom universal wheels 11. The scanning component 4 can then continuously scan the files or books it passes through to complete the inventory operation of the regular area.

[0039] When there is a narrow gap between the load-bearing column and the bookshelf in the inventory area, it is necessary to switch to the gap operation mode. The specific operation is as follows: First, loosen the bolts on the second fixed seat 15, remove the pressure plate, and release the clamping plate from the fixed constraint of the support rod 3, so that the support rod 3 can regain the freedom of rotation around the first connecting seat 21; then push the support rod 3 so that it rotates around the first connecting seat 21 synchronously with the second connecting seat 23 and the rotating rod 22 until the rotating rod 22 moves to the position of the buckle 17 of the positioning seat 16. At this time, the two upper and lower horizontal plates of the buckle 17 clamp the rotating rod 22 from both sides, and at the same time, the strong magnet inside the positioning seat 16 generates an attraction force on the metal rotating rod 22. Through the dual action of mechanical clamping and magnetic attraction, the rotating rod 22 is firmly fixed, thereby keeping the support rod 3 in the extended position at the front side of the inventory cart 1. In this state, the inventory cart 1 can stay outside the gap, and the support rod 3 can drive the scanning component 4 to extend into the narrow gap alone. Since the scanning component 4 has been pre-adjusted to the height corresponding to each shelf in the gap, no additional adjustment is needed to complete the accurate scanning of the files or books in the gap, thus achieving blind spot inventory.

[0040] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows:

[0041] 1. Eliminates blind spots in inventory between load-bearing columns and bookshelves: By rotating the hinge structure of the first connecting seat, rotating rod, and second connecting seat in the assembly, the extension direction of the support rod can be adjusted, so that the inventory cart does not need to enter the narrow gap between the load-bearing column and the bookshelf, but only the scanning component can be inserted into the gap to achieve effective inventory of the archives and books in the gap.

[0042] 2. Ensure the effectiveness of scanning operations: All second connecting seats and support rods are fixed as one piece, which ensures that the support rods maintain a stable posture during rotation and adjustment, and avoids the scanning components from shifting due to structural loosening; at the same time, the scanning components on the support rods can directly scan the documents and books in the gaps without additional adjustment of the scanning angle, ensuring the accuracy of inventory data and the efficiency of scanning operations;

[0043] 3. Reduce the risk of collisions during operation: Since the inventory cart does not need to enter narrow gaps, it can complete the inventory simply by extending the scanning components through the rotating rod. This effectively avoids collisions between the inventory cart and load-bearing columns, bookshelves, or archives and books in the gaps. It protects the inventory cart and scanning components from damage and also prevents the archives and books from shifting or breaking due to collisions, thus ensuring the safety of the collection and the integrity of the equipment.
