Description

Technical Field

[0001] This invention relates to the field of archives management technology, and in particular to a document anti-gravity bending protection device, an archive box, and its application method. Background Technology

[0002] In archival management, documents are typically stored upright in file boxes. Because paper is flexible, prolonged vertical storage can easily cause bending, and once bent, it's difficult to restore its flatness quickly. This not only affects the flatness of the paper documents, making retrieval and use inconvenient, but more seriously, the repeated bending stress on the paper and recording materials (ink, toner, etc.) accelerates aging and embrittlement, affecting the physical integrity of the documents and leading to permanent damage such as creases, tears, and wear, significantly shortening the document's lifespan.

[0003] Currently, most existing archival document protection measures on the market are highly targeted but lack versatility. For example, some special-material file boxes can only fit documents of specific sizes; others have complex structures, are inconvenient to install and use, and are difficult to promote and apply in different types of file boxes.

[0004] Therefore, there is an urgent need for a document anti-gravity bending protection device, a file box, and its application method to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a document anti-gravity bending protection device, an archive box, and its application method, to solve the technical problems of poor universality and difficulty in promotion of existing document protection measures. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a document anti-gravity bending protection device, comprising:

[0008] The support frame includes a first support plate and a second support plate disposed opposite to each other. The first support plate can be fixed to the inner wall of the file box, and the second support plate is used to compress the documents inside the file box.

[0009] An elastic support structure, with its two ends connected to the first support plate and the second support plate, respectively;

[0010] The locking assembly is used to control the locking or releasing of the elastic support structure.

[0011] Preferably, the locking assembly includes:

[0012] The first snap-fit ​​structure is connected to the first support plate;

[0013] The second snap-fit ​​structure is used to snap and fix with the first snap-fit ​​structure, and the second snap-fit ​​structure is connected to the second support plate.

[0014] Preferably, the first snap-fit ​​structure includes a button, a central shaft, a ball, and a compression spring, wherein:

[0015] The button and the ball are respectively disposed at both ends of the central axis and located on both sides of the first support plate;

[0016] A stop plate is provided on the central shaft, and a compression spring is provided between the stop plate and the first support plate.

[0017] Preferably, the sphere is connected to the central axis via a universal joint.

[0018] Preferably, the second snap-fit ​​structure includes a support rod, a compression spring, and a gripper, wherein:

[0019] The gripper includes at least two grippers, and the grippers are uniformly hinged to the support rod along the circumference of the support rod. The gripping groove formed by the ends of the grippers approaching each other can accommodate the sphere.

[0020] A compression spring is provided between the support rod and the second support plate.

[0021] Preferably, both the first support plate and the second support plate are rectangular plates, and the width and thickness of the first support plate and the second support plate are the same, and the length of the first support plate is less than the length of the second support plate.

[0022] A file box includes a box body, a box cover connected to the box body, and the aforementioned document anti-gravity bending protection device, wherein a first support plate is fixedly connected to the inner side wall of the box body.

[0023] Preferably, the side wall of the box is provided with an opening for the button of the document anti-gravity bending protection device to extend.

[0024] A method for applying the above-mentioned document anti-bending protection device includes the following steps:

[0025] S1: Select the first and second support plates that are compatible with the specifications of the file box. Connect the two through the elastic support structure to form a support frame. Press the first and second support plates repeatedly in opposite directions to make the elastic support structure alternate between compressed and natural states to verify that the connection between the two is stable and without loosening.

[0026] S2: Fix the second snap-fit ​​structure of the locking assembly to the second support plate, and fix the first snap-fit ​​structure to the first support plate. Repeatedly switch the locking and unlocking states of the first snap-fit ​​structure and the second snap-fit ​​structure to verify that the locking assembly operates normally without jamming.

[0027] S3: Place the entire locking protective device into the file box and adjust it to the center of the box.

[0028] S4: After placing the document to be protected vertically into the box, manually press the button of the first snap-fit ​​structure through the opening on the side wall of the box to disengage and unlock the first snap-fit ​​structure from the second snap-fit ​​structure. The elastic support structure releases its elastic force, pushing the second support plate towards the document and squeezing the document, so that the document is tightly attached to the inner wall of the box and keeps the document vertical and does not bend.

[0029] S5: Fold the lid of the file box back to close it with the body, and place the entire file box into the filing cabinet to complete the storage.

Through the cooperation of the support frame, the elastic support structure, and the locking assembly, the document is fixed and supported, offsetting the bending stress caused by gravity. This effectively prevents bending and deformation of the document, protects its physical integrity, and extends its service life. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0040] Figure 1 This is a structural schematic diagram of this embodiment, as shown below. Figure 1 As shown, this embodiment provides a document anti-gravity bending protection device, including: a support frame, an elastic support structure 3, and a locking assembly. The support frame includes a first support plate 1 and a second support plate 2 disposed opposite to each other. The first support plate 1 can be fixed to the inner wall of the file box, and the second support plate 2 is used to compress the document 10 inside the file box. The two ends of the elastic support structure 3 are respectively connected to the first support plate 1 and the second support plate 2; the locking assembly is used to control the locking or releasing of the elastic support structure 3.

[0041] Specifically, in this embodiment, both the first support plate 1 and the second support plate 2 are rectangular plates arranged in parallel. In use, the first support plate 1 can be fixed to the inner wall of the file box by means of adhesion, snap-fit, or bolts. The side of the second support plate 2 away from the first support plate 1 is flat, used to fully conform to the side of the document 10 inside the file box and apply uniform compressive force. The elastic support structure 3 is at least one elastic element evenly distributed along the length of the support frame, with both ends detachably connected to the inner sidewall of the first support plate and the inner sidewall of the second support plate, respectively, or integrally formed. Optionally, the elastic support structure 3 is a compression spring. A locking assembly is disposed between the first support plate 1 and the second support plate 2, and located beside the elastic support structure 3. It is used to lock the elastic support assembly in a pre-compressed state when not in operation, and to release the elastic support structure 3 in operation to generate a pushing force towards the document 10.

[0042] This document anti-gravity bending protection device consists of a support frame comprising a first support plate 1 and a second support plate 2 arranged opposite to each other. The first support plate 1 can be fixed to the inner wall of the file box, and the second support plate 2 is used to compress the document 10 inside the file box. The first support plate 1 and the second support plate 2 are connected by an elastic support structure 3, and a locking assembly is used to control the locking or releasing of the elastic support structure 3. The structure is simple. Through the cooperation of the support frame, the elastic support structure, and the locking assembly, the document 10 is fixed and supported, offsetting the bending stress of the document 10 caused by gravity. It can effectively prevent the document from bending or deforming, protect the physical integrity of the document, and extend the service life of the document.

[0043] As an optional implementation, the locking assembly includes a first snap-fit ​​structure and a second snap-fit ​​structure. The first snap-fit ​​structure is connected to the first support plate 1, and the second snap-fit ​​structure is used to snap-fit ​​and fix to the first snap-fit ​​structure. The second snap-fit ​​structure is connected to the second support plate 2.

[0044] In this embodiment, the first snap-fit ​​structure is fixedly connected to the inner wall of the first support plate by bolts or embedding, with the snap-fit ​​end of the first snap-fit ​​structure facing the second support plate 2. The second snap-fit ​​structure is fixedly connected to the inner wall of the second support plate by welding or snap-fit ​​connection, with its snap-fit ​​end matching the snap-fit ​​end of the first snap-fit ​​structure. The two are locked together by mechanical engagement, and the elastic support component is released by external force triggering separation.

[0045] Specifically, such as Figure 1 and Figure 2As shown, the first snap-fit ​​structure in this embodiment includes a button 7, a central shaft 11, a ball 5, and a compression spring 6. The button 7 and the ball 5 are respectively located at both ends of the central shaft 11 and on both sides of the first support plate 1. A stop plate 12 is provided on the central shaft 11, and a compression spring 6 is provided between the stop plate 12 and the first support plate 1.

[0046] In this embodiment, the ball 5 is connected to the central shaft 11 via a universal joint. The button 7 is located on the side of the first support plate 1 facing the inner wall of the file box, and the ball 5 is located on the side of the first support plate 1 facing the second support plate 2. The central shaft 11 passes through a through hole in the first support plate 1, with a clearance fit between the inner wall of the through hole and the central shaft 11. A stop plate 12 is fixedly fitted onto the central shaft 11, and a compression spring 6 is provided between the stop plate 12 and the side wall of the first support plate 1. In its natural state, the compression spring 6 pushes the stop plate 12, causing the central shaft 11 to extend outward, keeping the ball 5 in the extended state. Compared to a rigid connection, the universal joint connection between the ball 5 and the central shaft 11 allows the ball 5 to rotate adaptively with the separation direction of the second locking structure during unlocking, resulting in less separation resistance, easier unlocking operation, and a longer service life.

[0047] like Figure 3 As shown, the second snap-fit ​​structure includes a support rod 13, a compression spring 14, and grippers 4. The grippers 4 include at least two, and are uniformly hinged to the support rod 13 along its circumference. The gripping groove formed by the ends of the grippers 4 approaching each other can accommodate the ball 5. A compression spring 14 is provided between the support rod 13 and the second support plate 2.

[0048] In this embodiment, preferably, 2-4 grippers 4 are provided, and the 2-4 grippers are evenly distributed along the circumference of the support rod 13. The inner sidewall of the gripper 4 is provided with an arc-shaped groove adapted to the sphere 5. When the ends of the grippers 4 come close to each other, they form a spherical or near-spherical clamping groove. The inner diameter of the clamping groove is adapted to the diameter of the sphere 5 and can accommodate the sphere 5. A compression spring 14 is provided between the rear end of the support rod 13 and the inner sidewall of the second support plate 2, which is used to push the grippers 4 to extend towards the first snap-fit ​​structure in a natural state.

[0049] As an optional implementation, in this embodiment, the first support plate 1 and the second support plate 2 have the same width and thickness, and the length of the first support plate 1 is less than the length of the second support plate 2. Optionally, both the ends of the first support plate 1 and the second support plate 2 are rounded.

[0050] In actual production and use, the dimensions of the support frame can be customized according to the specific dimensions of the file box to accommodate various file box sizes. The elastic support structure 3 and locking assembly can also be selected according to different usage needs to adapt to documents of different thicknesses, quantities, and sizes. This document anti-bending protection device provides effective anti-bending protection for commonly used A4 and A3 paper, as well as other special document sizes, greatly improving the device's versatility.

[0051] like Figure 4-6 As shown, this embodiment also provides a file box, including a box body 8, a box cover 9 connected to the box body 8, and the aforementioned document anti-gravity bending protection device. A first support plate 1 is fixedly connected to the inner side wall of the box body 8. Optionally, the first support plate is fully fitted to the inner side wall of the box body, and in this embodiment, the side wall of the box body 8 is provided with an opening for the button 7 of the document anti-gravity bending protection device to extend out.

[0052] By setting an opening on the side wall of the box body 8, the button 7 for the anti-gravity bending protection device for documents can be extended. When in use, the button can be operated through the opening without opening the box cover to unlock the elastic support component, avoiding disturbance to the neatly arranged documents when unlocking, thus improving the convenience of operation and the integrity of document placement.

[0053] This embodiment also provides a method for applying the above-mentioned document anti-gravity bending protection device, including the following steps:

[0054] S1: Select the first support plate 1 and the second support plate 2 that are compatible with the specifications of the file box. Connect the two through the elastic support structure 3 to form a support frame. Press the first support plate 1 and the second support plate 2 repeatedly in opposite directions to make the elastic support structure 3 alternate between the compressed state and the natural state to verify that the connection between the two is stable and without loosening.

[0055] S2: Fix the second snap-fit ​​structure of the locking assembly to the second support plate, and fix the first snap-fit ​​structure to the first support plate. Repeatedly switch the locking and unlocking states of the first snap-fit ​​structure and the second snap-fit ​​structure to verify that the locking assembly operates normally without jamming.

[0056] S3: Place the entire locking protective device into the box 8 of the file box, and adjust the device to the center position of the box;

[0057] S4: After placing the document to be protected vertically into the box, manually press the button 7 of the first snap-fit ​​structure through the opening on the side wall of the box to disengage and unlock the first snap-fit ​​structure from the second snap-fit ​​structure. The elastic support structure 3 releases its elastic force, pushing the second support plate 2 towards the document 10 and squeezing the document 10, so that the document 10 is in close contact with the inner wall of the box 8, keeping the document 10 vertical and not bent.

[0058] S5: Fold the lid 9 of the file box back to close it with the body 8, and put the entire file box into the filing cabinet to complete the storage.

[0059] Understandably, when the file box is no longer in use or when the anti-gravity bending protection device is no longer needed, the second support plate 2 can be manually pushed to bring the second locking structure closer to the first locking structure. Once the ball 5 touches the support rod 13, continue pushing the second support plate 2. At this time, under the action of the compression spring 14, the ends of the grippers 4 on the support rod 13 gradually move closer together to form a clamping groove that can accommodate the ball 5, until the ball 5 completely falls into the clamping groove, and the protection device is locked. If needed, repeat steps S4-S5.

[0060] By employing a document anti-gravity bending protection device, the structure is simple, installation and use are convenient, and no complex operation or professional skills are required. In actual archival management work, archival management personnel can quickly learn to use it without special training. At the same time, its manufacturing cost is relatively low, and the materials and components used are readily available, making it suitable for large-scale production and widespread application. In use, the elastic support structure 3 can provide uniform and stable support for the documents 10 inside the file box, effectively offsetting the bending stress caused by gravity, preventing bending, deformation and other problems, protecting the physical integrity of the documents, and extending their service life. This device is suitable for various sizes of file boxes and documents.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
