For example, in the office work of accounting professionals in the finance and accounting department, there are many invoices, vouchers and other documents that need to be classified and stored. For storing invoices and documents, invoice and document storage devices are used.

[0003] Regarding document storage devices, a search reveals that Chinese utility model patent publication number CN222040063U discloses a document storage device, such as... Figure 1 As shown, it mainly includes a storage box a, which has multiple partitions b inside, for storing and organizing files.

[0004] Existing document storage devices with similar technical solutions have been found to have areas for improvement in actual implementation: the storage box of the aforementioned document storage device cannot be folded, unfolded, or deformed, making it inconvenient to hang documents, and its flexibility of application needs to be improved. Utility Model Content

[0005] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a document storage device that solves the problems of existing document storage devices, such as the storage box not being able to be folded, unfolded and deformed, the inconvenience of hanging documents, and the need to improve the flexibility of application.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a document storage device, including document boxes, at least three document boxes, multiple document boxes are connected in a foldable and unfoldable manner by a rotating connector. In the folded state, multiple document boxes are also locked by a locking member that prevents them from unfolding. A hanging plate is rotatably connected to the last document box. The hanging plate is provided with a hanging hole. A pressure plate is connected to the inner side of the front wall of each document box by a spring. A pull rod that can pass through the front wall of the document box is provided on the front side of the middle part of the pressure plate. The upper part of the front wall and the rear wall of each document box is provided with a downwardly recessed arc groove. Multiple viewing holes are also provided on the front wall and the rear wall of the document box.

[0007] As a further improvement of this utility model, the rotating connector includes multiple first rotating connecting plates, each of which is provided with three rotating holes. Each file box has an upper insertion shaft, a middle insertion shaft, and a lower insertion shaft on its left and right sides from top to bottom. The left and right sides of three adjacent file boxes are each connected by a first rotating connecting plate. In the three adjacent file boxes, the upper insertion shaft of the file box in front, the middle insertion shaft of the file box in the middle, and the lower insertion shaft of the file box in the rear are rotatably connected to the rotating holes of the first rotating connecting plates.

[0008] As a further improvement of this utility model, the central insertion shaft of the frontmost file box and the lower insertion shaft on the rearmost file box are rotatably connected by a second rotating connecting plate.

[0009] As a further improvement of this utility model, it also includes two third rotating connecting plates. The third rotating connecting plates are provided with three rotating holes. The middle insertion shaft of the last file box and the upper insertion shaft on the front file box are inserted into the two rotating holes of the third rotating connecting plates and are rotatably connected through the third rotating connecting plates. A plug is provided at the bottom of both the left and right sides of the hanging plate. The two plugs of the hanging plate are rotatably connected to the rotating holes at the last side of the two third rotating connecting plates.

[0010] As a further improvement of this utility model, the locking component includes two locking plates, each with a plurality of locking holes. The number of locking holes is the same as the number of file boxes. When the file boxes are folded, the plurality of locking holes of the locking plates are sequentially and removably inserted into the lower insertion shafts of the file boxes.

[0011] As a further improvement of this utility model, each end of the lower insertion shaft is provided with a rubber head with an opening. The locking hole of the locking plate can be inserted and removed through the rubber head, and after the locking plate is installed, the rubber head limits the locking hole.

The front end of the pull rod passes through the pull hole and is connected to a pull plate. The pull rod can be pulled back and forth on the pull hole.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] 1. By setting up multiple file boxes, documents and receipts can be categorized and stored. These boxes are connected by rotating connectors, allowing them to fold and unfold. A hanging plate is rotatably connected to the rearmost file box. Therefore, the file boxes can be folded up to form a large box at the same height, storing documents and receipts. When hanging is needed, the file boxes can be unfolded, forming a hanging bracket from top to bottom, allowing them to be suspended inside a filing cabinet. This makes the application more flexible and versatile. Furthermore, before unfolding and hanging, the file boxes can be folded up and placed on a table for staff to sort and organize before hanging. Even when stored in the folded state, the file boxes can be unfolded for easy retrieval of documents and receipts.

[0015] In addition, by incorporating locking mechanisms, the document box can be locked in place when folded, preventing it from unfolding unnecessarily.

[0016] A spring-loaded pressure plate is installed on the inner front wall of the document box, with a pull rod at the front end of the pressure plate. This allows the documents inside the document box to be compressed, preventing them from collapsing and deforming downwards and forming more wrinkles when there are fewer documents inside and the document box has a larger space.

[0017] In addition, each document box has a downward-recessed arc-shaped groove on the upper part of the front and rear walls, which makes it easy to take out the document from the arc-shaped groove when the document is small.

[0018] In addition, the front and rear walls of the document box are provided with multiple viewing holes, which serve two purposes: firstly, for decoration, and secondly, to allow observation of the documents inside the document box.

[0019] 2. By setting the rotating connector as a structure of multiple first rotating plates, the file box can be unfolded or folded.

[0020] 3. By setting the locking element as a locking plate structure, the locking plate is provided with multiple locking holes. When the document box is in the folded state, the multiple locking holes of the locking plate are sequentially and removably inserted into the lower insertion shafts of multiple document boxes, thereby preventing the document boxes from rotating relative to each other.

[0021] 4. By providing a rubber head at the end of the lower insertion shaft, the locking hole can be limited to prevent the locking plate from easily sliding off the lower insertion shaft. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 2-6 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0031] For ease of description, the coordinate system is defined as follows: Figure 2 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0032] This utility model discloses a document storage device for invoices. (Refer to...) Figure 2 and Figure 3 A document storage device includes five document boxes 1. The document boxes 1 are connected in a foldable and unfoldable manner by a rotating connector. A hanging plate 3 is rotatably connected to the last document box 1. The hanging plate 3 is provided with a hanging hole 4.

[0033] Specifically, the rotating connector includes multiple first rotating connecting plates 10 and two third rotating connecting plates 15. Each first rotating connecting plate 10 has three rotating holes. Each file box 1 has an upper insert shaft 11, a middle insert shaft 12, and a lower insert shaft 13 on its left and right sides from top to bottom. The left and right sides of three adjacent file boxes 1 are each connected by a first rotating connecting plate 10. In the three adjacent file boxes 1, the upper insert shaft 11 of the front file box 1, the middle insert shaft 12 of the middle file box 1, and the lower insert shaft 13 of the rear file box 1 are rotatably connected to the rotating holes of the first rotating connecting plates 10, so that the file boxes 1 can be unfolded or folded. In addition, the middle insert shaft 12 of the frontmost file box 1 and the lower insert shaft 13 of the file box 1 behind it (the second file box 1 from the front) are also rotatably connected by a second rotating connecting plate 14. The third rotating connecting plate 15 has three rotating holes. The middle insertion shaft 12 of the last file box 1 and the upper insertion shaft 11 of the file box 1 on the front side (the second file box 1 from the back) are inserted into the two rotating holes of the third rotating connecting plate 15 and are rotatably connected through the third rotating connecting plate 15. The bottom of the left and right sides of the hanging plate 3 is provided with a plug 16. The two plugs 16 of the hanging plate 3 are rotatably connected to the two rotating holes on the last side of the third rotating connecting plate 15.

[0034] like Figure 2 As shown, in the folded state, the multiple document boxes 1 are also connected and locked by locking components that prevent them from unfolding. These locking components can be used to lock the document boxes 1 when they are folded, preventing them from unfolding arbitrarily. Specifically, the locking components include two locking plates 2, each with multiple locking holes 17. The number of locking holes 17 is the same as the number of document boxes 1. When the document boxes 1 are folded, the multiple locking holes 17 of the locking plates 2 are sequentially and removably inserted into the lower insertion shafts 13 on the multiple document boxes 1, thereby preventing the document boxes 1 from rotating relative to each other. When it is necessary to unfold the document boxes 1, the locking plates 2 are first removed, and then the document boxes 1 are unfolded. Furthermore, as... Figure 4 As shown, each end of the lower insertion shaft 13 is provided with a rubber head 18. The rubber head 18 has an opening, and the locking hole 17 of the locking plate 2 can be inserted and removed through the rubber head 18. After the locking plate 2 is installed, the rubber head 18 limits the locking hole. Therefore, the rubber head 18 can be squeezed to make the locking plate 2 fit on the lower plug 16. After the locking plate 2 is installed, the rubber head 18 is released, and the rubber head 18 is larger than the locking hole of the locking plate 2, thus limiting the locking plate 2 and preventing the locking plate 2 from easily sliding off the lower insertion shaft 13.

[0035] like Figure 5 and Figure 6As shown, each document box 1 has a pressure plate 6 connected to its inner front wall via a spring 5. A pull rod 7, extending through the front of the middle of the pressure plate 6, is provided. A pull hole is located on the front wall of the document box 1 at the position where the pull rod 7 is located. The front end of the pull rod 7 extends through the pull hole and is connected to a pull plate 19. The pull rod 7 can be pulled back and forth through the pull hole. When placing documents, the pressure plate 6 can be pulled forward. After placing the documents, the pull rod 7 is released, and the pressure plate 6, under the action of the spring 5, presses backward or blocks the documents, preventing them from tipping over. The pressure plate 6, with its pull rod 7 at its front end, is located on the inner front wall of the document box 1, thus compressing the documents inside the document box 1 to prevent them from collapsing and deforming, forming wrinkles, when the document box 1 is low in quantity.

[0036] like Figure 3 and Figure 6 As shown, each document box 1 has a downward-recessed arc-shaped groove 8 on the upper part of the front and rear walls. When the document is small, it is convenient to take out the document from the arc-shaped groove 8.

[0037] like Figure 2 and Figure 3 As shown, the front and rear walls of the document box 1 are also provided with multiple viewing holes 9; the viewing holes 9 serve two purposes: firstly, they can be used for decoration, and secondly, they can be used to observe the documents inside the document box 1.

[0038] The main technical advantages of this invention are as follows: By setting multiple file boxes 1, different documents can be classified and stored. The multiple file boxes 1 are connected by rotating connectors, allowing them to be folded and unfolded. A hanging plate 3 is rotatably connected to the last file box 1. Therefore, the file boxes 1 can be folded up according to actual needs, with multiple file boxes 1 at the same height, forming a large box from front to back for storing documents. When hanging is needed, the file boxes 1 can be unfolded, forming a hanging bracket from top to bottom, allowing them to be hung in a filing cabinet, making the application more flexible and versatile. Furthermore, before unfolding and hanging the file boxes 1, they can be folded up and placed on a table for staff to classify and organize before hanging. Additionally, even when stored in the folded state, the file boxes 1 can be unfolded for easy retrieval of documents.
