An accounting document storage device

Abstract

This utility model discloses an accounting document storage device. By incorporating a horizontally sliding slide plate inside the storage box and a locking mechanism within the slide plate, the device achieves precise positioning and stable fixation of the slide plate. The locking mechanism employs a mechanical compression mechanism involving a sliding rod, a trapezoidal block, and a positioning rod. When the sliding rod moves downwards, the trapezoidal block acts on the positioning rod along its inclined surface, causing the positioning rod to move towards the inner wall of the storage box and form a double-sided friction limit with the rubber strip, thus reliably locking the slide plate. Simultaneously, the positioning mechanism locks the position of the sliding rod, providing greater operational space when retrieving or replacing documents.

Description

Technical Field

[0001] This utility model belongs to the field of document storage devices, specifically, it relates to an accounting document storage device. Background Technology

[0002] In modern accounting management and financial record organization, there are numerous and varied types of invoices, vouchers, and receipts, most of which are paper-based and prone to creases, disarray, loss, or dampness. To ensure the integrity of accounting information and the traceability of voucher verification, how to classify, secure, and efficiently store invoices has become a pressing practical problem in accounting. Currently, common invoice storage methods mainly consist of folders, invoice bags, or traditional storage boxes. While these structures can achieve centralized storage to some extent, they mostly employ simple stacking or insert designs, lacking effective limiting and securing mechanisms. This leads to invoices easily slipping, bending, or even becoming chaotically stacked during handling. Furthermore, some devices require manual handling or external clamps for holding, which is not only cumbersome but also prone to wear and tear on invoices after long-term use, affecting their preservation integrity and the accuracy of later archiving and verification.

[0003] Chinese Patent Publication No. CN221969270U discloses a document storage device for easy organization and management, including a storage box. The storage box has several storage spaces inside, and the inner walls of each storage space are provided with guide grooves. Guide rods and return springs are fixedly connected to the inner walls of each guide groove. The advantages of this invention are: through the coordinated arrangement of guide grooves, guide rods, return springs, guide sliders, moving baffles, fixed baffles, adjusting grooves, limiting grooves, and folding plate structures, multiple documents can be tightly packed together. Furthermore, the distance between two folding plate structures can be adjusted to a suitable level according to the length of the documents. This allows the document storage device to effectively store documents of varying lengths, preventing document misalignment and subsequent confusion, facilitating subsequent retrieval, and improving the practicality and structural flexibility of the document storage device.

[0004] While the document in the comparison file achieves a certain degree of document sorting and centralized storage in terms of structure, its baffle structure design is rather simplistic and lacks effective limiting and locking mechanisms. In actual use, the baffle typically moves simply by sliding along a guide rail, without any mechanical locking or friction limiting device to fix its position. When the user needs to replace or remove documents, they must continuously push the baffle by hand to keep it open; otherwise, the baffle will return to its original position under the action of elasticity or its own weight, resulting in limited operating space and increasing the user's operational burden.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an accounting professional invoice storage device, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: An accounting document storage device includes: a plurality of storage boxes connected together, each of the storage boxes having a sliding plate that can reciprocate in the horizontal direction inside, the sliding plate being elastically connected to the inner wall of the storage box through an elastic element; The slide plate has a groove along its length inside, and a locking mechanism for limiting and locking the position of the slide plate is slidably installed inside the groove; the upper edge of the storage box is connected to a flip-up cover plate through a hinge shaft for sealing and protecting the tickets. The locking mechanism includes a sliding rod that slides vertically along the channel. A trapezoidal block is fixedly connected to the lower end of the sliding rod. Through slots are opened on both sides of the channel. A horizontally extendable positioning rod is elastically connected inside the through slot. The positioning rod and the trapezoidal block form a mutual pressing fit. When the trapezoidal block moves down, the positioning rod shifts towards the inner wall of the storage box under the pressing action, thereby locking and fixing the slide plate. A positioning mechanism is provided above the slide bar to control its up and down movement. One end of the positioning rod is fixedly connected to a connecting block. Positioning grooves that are adapted to the connecting block are respectively opened on both sides of the sliding plate. The inner wall of the positioning groove is provided with anti-slip friction texture. The two sides of the storage box are provided with slots that are opposite to the friction texture. Rubber strips that fit the friction texture are installed inside the slots, so as to form bidirectional friction limit when the sliding plate clamps the ticket, thereby improving the stability and anti-slip performance after the ticket is clamped.

[0008] Optionally, the bottom of the storage box has a vertical groove, and a guide rail is fixedly installed inside the groove. A slider that slides with the guide rail is fixedly installed at the corresponding position on the bottom of the slide plate. A first spring is connected between one side of the slide plate and the inner wall of the storage box, which is used to push the slide plate to automatically reset after unlocking.

[0009] Optionally, two opposing cylindrical bodies are fixedly connected to the upper edge of the storage box, and two insert rods inserted into the cylindrical bodies are fixedly connected to both sides of the cover plate.

[0010] Optionally, the positioning mechanism includes a rotating block rotatably connected to the upper end of the slide rod, and an arc-shaped rod with an L-shaped cross-section is fixedly connected below the rotating block. An arc-shaped groove matching the shape of the arc-shaped rod is provided above the slide rod. The opening diameter of the arc-shaped groove is larger than the width of the lower end of the L-shaped rod so that flexible engagement and disengagement can be achieved in the rotation state.

[0011] Optionally, a groove is provided above the slide for the rotating block to enter, and an arc-shaped groove is provided at the bottom of the inner wall of the groove.

[0012] Optionally, an annular baffle is fixedly connected to the outer periphery of the slide rod, and a cylindrical groove that slides with the baffle is opened along the direction of the slide rod on the inner wall of the channel. A second spring sleeved on the outer periphery of the slide rod is connected between the lower part of the baffle and the inner wall of the cylindrical groove to provide the return force of the slide rod. A guide groove is opened at the bottom of the inner wall of the through groove, and a guide block that slides inside the guide groove is fixedly connected to the lower part of the positioning rod. A third spring is provided between the guide block and the guide groove to automatically reset the positioning rod to the initial position when the trapezoidal block rises.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: This invention achieves precise positioning and stable fixation of the slide plate by incorporating a horizontally sliding slide plate inside the storage box and a locking mechanism within the slide plate. The locking mechanism employs a mechanical compression mechanism involving a sliding rod, a trapezoidal block, and a positioning rod. When the sliding rod moves downwards, the trapezoidal block acts on the positioning rod along its inclined surface, causing the positioning rod to move towards the inner wall of the storage box and form a double-sided friction limit with the rubber strip, thus reliably locking the slide plate. Simultaneously, the positioning mechanism locks the position of the sliding rod, providing greater operational space when retrieving or replacing documents.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Please see Figure 1-4 As shown, this embodiment provides an accounting professional invoice storage device, including a plurality of storage boxes 1 connected to each other. Each storage box 1 has a sliding plate 2 that can move back and forth in the horizontal direction inside. The sliding plate 2 is elastically connected to the inner wall of the storage box 1 through an elastic element. The interior of the slide plate 2 is provided with a channel 3 along its length, and a locking mechanism for limiting and locking the position of the slide plate 2 is slidably installed inside the channel 3; the upper edge of the storage box 1 is connected to a flip-up cover plate 4 through a hinge shaft for sealing and protecting the tickets; the cover plate 4 can be connected to the storage box 1 through a buckle.

[0020] The locking mechanism includes a slide rod 5 that slides vertically along the channel 3. A trapezoidal block 6 is fixedly connected to the lower end of the slide rod 5. Through slots 7 are opened on both sides of the channel 3. A horizontally extendable positioning rod 8 is elastically connected inside the through slot 7. The positioning rod 8 and the trapezoidal block 6 form a mutual pressing fit. When the trapezoidal block 6 moves down, the positioning rod 8 shifts towards the inner wall of the storage box 1 under the pressing action, thereby locking and fixing the slide plate 2. A positioning mechanism is provided above the slide bar 5 to control its up-and-down movement. A connecting block 9 is fixedly connected to one end of the positioning rod 8. Positioning grooves that match the connecting block 9 are respectively opened on both sides of the slide plate 2, and the inner walls of the positioning grooves are provided with anti-slip friction textures. Grooves corresponding to the friction textures are opened on both sides of the storage box 1. Rubber strips 10 that fit the friction textures are installed inside the grooves, thus forming bidirectional friction limiting when the slide plate 2 clamps the document, improving the stability and anti-slip properties after the document is clamped. The rubber strips are fixed inside the grooves with glue.

[0021] By incorporating a reciprocating sliding plate 2 inside the storage box 1, and utilizing elastic elements for self-resetting and buffering, the storage and retrieval of documents becomes smoother. The locking mechanism within the sliding plate 2 employs a combination of a vertical sliding rod 5 and a trapezoidal block 6, using mechanical compression to switch between clamping and releasing the documents. The compression engagement between the positioning rod 8 and the trapezoidal block 6 automatically achieves a locked state during operation, reducing displacement of the sliding plate 2 after clamping the documents.

[0022] In this embodiment, the bottom of the storage box 1 has a longitudinally formed straight groove, and a guide rail 11 is fixedly installed inside the straight groove. A slider that slides along the guide rail 11 is fixedly installed at a corresponding position on the bottom of the slide plate 2. A first spring 12 connects one side of the slide plate 2 to the inner wall of the storage box 1, which is used to push the slide plate 2 to automatically reset after unlocking. By setting a straight groove and a guide rail 11 at the bottom of the storage box 1, and installing a corresponding slider at the bottom of the slide plate 2, the reciprocating motion of the slide plate 2 is made to follow a fixed trajectory, avoiding shaking or deviation, and improving the stability and guiding accuracy of the structure. The first spring 12 between the slide plate 2 and the box body can automatically push the slide plate 2 back to its initial position and clamp the ticket after unlocking.

[0023] In this embodiment, two opposing cylindrical bodies 13 are fixedly connected to the upper edge of the storage box 1, and two insert rods inserted into the inside of the cylindrical bodies 13 are fixedly connected to both sides of the cover plate 4.

[0024] The positioning mechanism of this embodiment includes a rotating block 14 rotatably connected to the upper end of the slide rod 5. An L-shaped arc rod 15 is fixedly connected below the rotating block 14. An arc groove 16 matching the shape of the arc rod 15 is formed above the slide rod 5. The opening diameter of the arc groove 16 is larger than the width of the lower end of the L-shaped rod, allowing for flexible engagement and disengagement during rotation. The positioning mechanism employs a combination structure of the rotating block 14 and the L-shaped arc rod 15. The mechanical locking of the slide rod 5's vertical position is achieved through the rotating insertion action of the arc rod 15 within the arc groove 16. The design of the arc groove 16's opening being larger than the width of the lower end of the rod allows for smooth entry and exit of the device during rotation. The rotating block 14 is rotatably connected to the slide rod 5 via a bearing.

[0025] In this embodiment, a groove 17 is provided above the slide plate 2 for the rotating block 14 to enter, and an arc-shaped groove 16 is formed at the bottom of the inner wall of the groove 17. By providing a groove 17 above the slide plate 2 and arranging the arc-shaped groove 16 at the bottom of the groove 17, the rotating block 14 has sufficient rotation space during operation, avoiding structural interference or friction jamming.

[0026] In this embodiment, an annular baffle is fixedly connected to the outer periphery of the slide rod 5. A cylindrical groove 18 that slides and engages with the baffle is formed on the inner wall of the channel 3 along the direction of the slide rod 5. A second spring, sleeved on the outer periphery of the slide rod 5, is connected between the lower part of the baffle and the inner wall of the cylindrical groove 18 to provide a restoring force for the slide rod 5. A guide groove 19 is formed at the bottom of the inner wall of the through groove 7. A guide block that slides inside the guide groove 19 is fixedly connected to the lower part of the positioning rod 8. A third spring is provided between the guide block and the guide groove 19 to automatically reset the positioning rod 8 to its initial position when the trapezoidal block 6 rises. The cooperation between the baffle and the cylindrical groove 18 on the periphery of the slide rod 5 can prevent the slide rod 5 from shifting laterally after the locking mechanism is subjected to force, thereby improving the seismic resistance and durability of the structure. The second spring provides a vertical restoring force for the slide rod 5, ensuring that the system can automatically return to its initial state after unlocking. The guide groove 19 at the bottom of the through groove 7 cooperates with the guide block below the positioning rod 8 to ensure that the movement trajectory of the positioning rod 8 is stable during the squeezing and resetting process, and that no jamming occurs. The third spring provides a reverse elastic force after the trapezoidal block 6 rises, causing the positioning rod 8 to automatically return to its original position, thus forming a complete mechanical self-restoring system.

[0027] Working principle: In using this accounting document storage device, the operator first neatly places the documents to be stored on the slide plate 2 inside the storage box 1. Then, the slide plate 2 is pushed inwards, and under the rebound force of the elastic element, it automatically clamps, stably fixing the documents between the slide plate 2 and the inner wall of the storage box 1. When the top cover 4 is closed, its lower surface contacts and presses against the rotating block 14, causing the rotating block 14 to retract downwards into the groove 17 above the slide plate 2. As the rotating block 14 moves downwards, the sliding rod 5 connected below it also slides into the channel 3. During this process, the trapezoidal block 6 gradually descends and presses against the positioning rods 8 located in the through slots 7 on both sides along its own inclined surface. The positioning rods 8, after being subjected to force, shift laterally towards the inner wall of the storage box 1, thereby pushing the connecting block 9 at the end of the positioning rod 8 into the positioning groove on the side of the slide plate 2. At the same time, the outer wall of the positioning block is in contact with the rubber strip 10 set on the side wall of the storage box 1, and the friction texture and the rubber strip 10 form a bidirectional friction limiting effect, thereby locking and stabilizing the slide plate 2 in the current position and preventing the ticket from sliding or shifting during handling or vibration.

[0028] When it is necessary to remove or replace the ticket, the user simply presses down on the slide bar 5, causing the slide bar 5 to move the trapezoidal block 6 upward, releasing the pressure between it and the positioning rod 8. The positioning rod 8 then automatically returns to its original position under the elastic action of the second spring, thereby unlocking the slide plate 2 and restoring its sliding capability. At this time, the operator can freely adjust the position of the slide plate 2 according to the number and thickness of the tickets without continuously pushing the slide plate 2 to keep it open. After the ticket adjustment is completed, the arc-shaped rod 15 below the rotating block 14 enters the corresponding arc-shaped groove 16 above the slide bar 5. By gently rotating the rotating block 14, the L-shaped arc-shaped rod 15 and the arc-shaped groove 16 are fitted together, achieving a secondary locking of the slide bar 5.
