Description

Technical Field

[0001] The present invention relates to the technical field of file cabinets, in particular to a size-adjustable confidentiality file cabinet. Background Art

[0002] In the existing technology, confidential filing cabinets are cabinets specially designed for storing sensitive information and documents. Their main features are high confidentiality and protection performance. Such filing cabinets are usually used in government agencies, banks, corporate technical departments and archives departments to store college entrance examination papers, technical research and development documents, state secrets, etc.

[0003] However, the existing confidential filing cabinets generally have a simple structure, which only allows confidential documents to be stored directly in them safely. When confidential documents are stored in a higher position in the cabinet, it is not convenient for staff to take them out, which increases the risk of accidentally dropping confidential documents or folders during the process of taking them out, thereby causing damage to the confidential documents. At the same time, since it is inconvenient to take and put files in the high position of the cabinet, staff need to spend more time and energy to complete these operations, which affects their work efficiency and causes delays in work tasks.

[0004] In addition, existing confidential filing cabinets only place confidential documents on the shelves therein, and the space on the shelves cannot be adjusted according to the size of the documents. When placing documents, more unnecessary space will be required due to the documents being too large or too small, resulting in a waste of space. If the filing cabinet is too large, it will occupy a large amount of space and cannot be fully utilized. If the cabinet is too small, it cannot meet the storage needs, and the interior of the filing cabinet cannot be properly organized and classified according to the size of the confidential documents, which will cause the confidential documents to be directly piled up, making it inconvenient to find and take out, and increasing the difficulty of organization and management.

[0019] (2) Through the size adjustment mechanism, when the staff needs to store confidential documents, the rotating column rotates continuously, causing the rotating block 2 to slide along the sliding groove 2. The rotating block 2 drives the isolation plate to move in the horizontal direction through the sliding block, so that the spacing between the multiple isolation plates is gradually increased from the middle to the two ends. When the user places the documents, the thicker documents are placed on both sides and the thinner documents are placed in the middle. In this way, the user can flexibly organize and store the documents according to the actual needs and the size of the documents, thereby improving the efficiency and convenience of the document storage and maximizing the use of the available space. The partitions can be moved and adjusted as needed to make full use of the internal space of the filing cabinet and avoid space waste.

[0020] (3) Through the size adjustment mechanism, when the staff needs to take out the documents, they can pull the cylindrical rod to move the document box downward. Even if the cylindrical rod leaves the front of the document box and cannot provide protection, the confidential documents can still be stably stored in the document box due to the setting of the silicone gasket, thereby preventing the confidential documents from being damaged when the filing cabinet is hit by external force. At the same time, when taking and placing confidential documents, multiple silicone gaskets are set to hold the confidential documents, thereby improving the stability of the confidential document storage.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Embodiments of the present invention

[0035] Please refer to Figures 1 to 4As shown, a size-adjustable confidential filing cabinet, used for a confidential filing cabinet, includes a filing cabinet body 1, a cabinet door 2 is rotatably connected to the upper portion of the filing cabinet body 1, and a door handle 3 is rotatably connected to the front side of the cabinet door 2. A size-adjustable confidential filing cabinet includes: a pick-and-place mechanism 4 and a size adjustment mechanism 5, the pick-and-place mechanism 4 is arranged inside the filing cabinet body 1, the size adjustment mechanism 5 is arranged inside the filing cabinet body 1, and the size adjustment mechanism 5 is arranged above the pick-and-place mechanism 4;

[0036] The take-and-place mechanism 4 is used to facilitate taking out documents;

[0037] The size adjustment mechanism 5 is used to adjust the size to facilitate the placement of documents;

[0038] A pair of cabinet doors 2 are symmetrically arranged along the middle horizontal plane of the filing cabinet body 1, and a pair of door handles 3 are symmetrically arranged along the middle horizontal plane of the filing cabinet body 1;

[0039] The pick-and-place mechanism 4 includes a rotating block 401, which is rotatably connected to the inner wall of the filing cabinet body 1. A cylindrical housing 402 is fixedly connected to the lower surface of the rotating block 401. A spring 403 is slidably connected to the interior of the cylindrical housing 402. The end of the spring 403 away from the rotating block 401 abuts against a sliding post 404. The end of the sliding post 404 away from the spring 403 is fixedly connected to a fixed block 405. The middle portion of the fixed block 405 is rotatably connected to a connecting rod 406.

[0040] The inner bottom surface of the filing cabinet body 1 is fixedly connected to a support plate 407, the outer surface of the support plate 407 is rotatably connected to a second connecting rod 408, the middle portion of the second connecting rod 408 is rotatably connected to a file placement box 409, and the end of the second connecting rod 408 away from the support plate 407 is fixedly connected to a cylindrical rod 410;

[0041] The cylindrical housing 402 is sleeved on the sliding post 404. The upper end of the spring 403 abuts against the inner upper side of the cylindrical housing 402. The middle portion of the connecting rod 406 is rotatably connected to the support plate 407. The upper end of the connecting rod 406 is rotatably connected to the outer side of the document storage box 409.

[0042] When the file cabinet body 1 is hit by external force, the cylindrical rod 410 improves the stability of the file, and the spring 403 is used to keep the file placement box 409 against the inner wall surface of the file cabinet body 1.

[0043] The effects achieved by this embodiment are as follows: the structure of existing confidential file cabinets is generally relatively simple, and confidential documents can only be safely stored directly in them. When confidential documents are to be stored in a higher position of the cabinet, it is not convenient for staff to take and put them, which increases the risk of accidentally dropping confidential documents or folders during the process of taking and putting, and thus causes damage to the confidential documents. At the same time, since it is inconvenient to take and put files high up in the cabinet, staff need to spend more time and energy to complete these operations, which affects the work efficiency of staff and causes delays in work tasks. Compared with the existing technology, through the provision of the taking and putting mechanism 4, when the staff needs to take and put confidential documents, they can manually pull the cylindrical rod 410, and the cylindrical rod 410 drives the second connecting rod 408 to rotate around the point of rotation connection with the support plate 407, so that the second connecting rod 408 drives the rotationally connected file placement box 409 to swing downward, thereby facilitating the staff to take and put confidential documents. Moreover, since the files high up in the cabinet are easy to take and put, staff do not need to spend more time and energy to complete these operations, thereby improving work efficiency.

[0044] Further examples:

[0045] Please refer to Figures 5 to 8 As shown, the size adjustment mechanism 5 includes a mechanism housing 501, which is fixedly connected to the upper portion of the document placement box 409. A circular hole 502 is formed on one side of the mechanism housing 501 near the connecting rod 1 406. A rotating column 503 is rotatably connected to the circular hole 502. A sliding groove 1 504 is formed in the middle of the rotating column 503, and a sliding groove 2 505 is formed on the smooth surface of the rotating column 503.

[0046] A guide rod 506 is fixedly connected to the inner wall surface of the mechanism housing 501. A sliding block 507 is slidably connected to the middle portion of the guide rod 506. A second rotating block 508 is rotatably connected to the side of the sliding block 507 near the rotating column 503. An isolation plate 509 is fixedly connected to the lower surface of the sliding block 507. A silicone gasket 510 is fixedly connected to the front side of the isolation plate 509.

[0047] The circular holes 502 are symmetrically opened on the left and right sides of the mechanism housing 501, the slide groove 1 504 is a circular slide groove, the slide groove 2 505 is a spiral slide groove with a larger ring distance, and the slide groove 2 505 is symmetrically opened on the rotating column 503 based on the vertical plane of the slide groove 1 504. There are two guide rods 506, and both are fixedly connected to the inside of the mechanism housing 501. The rotating block 2 508 is slidably connected in the slide groove 2 505. The sliding blocks 507, the rotating blocks 2 508 and the isolation plates 509 are all provided in equal numbers, and the silicone gaskets 510 are fixedly connected to the left and right sides of the isolation plates 509.

[0048] Among them: the mechanism housing 501 is fixedly connected to the upper part of the document placement box 409, the rotating column 503 rotates under the drive of the internal motor, the number of isolation plates 509 is determined according to actual usage, and the isolation plates 509 are used to provide isolation for documents of different sizes. The silicone gasket 510 is used to store the documents more stably in the document placement box 409.

[0049] The effects achieved by this embodiment are as follows: the existing confidential file cabinets only place confidential documents in them, and do not have the relevant size adjustment mechanism 5. Since the internal space cannot be adjusted, the cabinet may be too large or too small, resulting in space waste. If the file cabinet is too large, it will occupy a lot of space and cannot be fully utilized. If the cabinet is too small, it cannot meet the storage needs, and the file cabinet cannot be reasonably sorted and classified according to the size of the confidential documents, which will cause the confidential documents to be directly piled up together, making it inconvenient to find and take out, and increasing the difficulty of sorting and management. Compared with the existing technology, the size adjustment mechanism 5 is set to be able to adjust the size of the confidential documents when the staff needs it. When confidential documents are to be stored, the rotating column 503 rotates continuously, causing the second rotating block 508 to slide along the second slide groove 505. The second rotating block 508 drives the isolation plate 509 to move horizontally through the sliding block 507, thereby increasing the distance between the multiple isolation plates 509, thereby enabling the filing cabinet to be freely adjusted according to files and folders of different sizes. In this way, users can flexibly organize and store files according to actual needs and file sizes, improving the efficiency and convenience of file storage and maximizing the use of available space. The partitions can be moved and adjusted as needed to fully utilize the internal space of the filing cabinet and avoid space waste.

[0050] In addition, the existing confidential file cabinets only place confidential documents therein, but cannot make the confidential documents more stable. If the file cabinet cannot provide sufficient stability, the documents will be damaged by squeezing, folding or bending, which will affect the integrity and life of the documents. Compared with the existing technology, the size adjustment mechanism 5 is set, and when the staff needs to take the documents, they can pull the cylindrical rod 410 to drive the document placement box 409 to move downward. Even if the cylindrical rod 410 leaves the front of the document placement box 409 and cannot provide protection, due to the setting of the silicone gasket 510, the confidential documents can still be stably stored in the document placement box 409, thereby avoiding damage to the confidential documents when the file cabinet is hit by external force. At the same time, when taking and placing confidential documents, multiple silicone gaskets 510 are set to hold the confidential documents, thereby improving the stability of confidential document storage.

[0051] The complete usage steps and working principle of the above embodiment are as follows:

[0052] In the initial state:

[0053] Pick-and-place mechanism 4: Spring 403 is in a balanced state;

[0054] Size adjustment mechanism 5: multiple sliding blocks 507 are arranged in a relatively concentrated manner in the middle of the guide rod 506, and the rotating column 503 rotates counterclockwise driven by the internal motor;

[0055] The following is the working process of the retrieval mechanism 4 for facilitating the staff to retrieve and place confidential documents:

[0056] When in use, the cylindrical rod 410 is manually pulled, so that the cylindrical rod 410 drives the fixedly connected connecting rod 2 408 to swing clockwise under the restriction of the support plate 407, and at the same time, the connecting rod 2 408 drives the rotatably connected document placement box 409 to move synchronously, and the document placement box 409 drives the rotatably connected connecting rod 1 406 to swing synchronously under the restriction of the support plate 407, and then the connecting rod 1 406 drives the rotatably connected fixed block 405 to swing clockwise. At this time, the fixed block 405 drives the fixedly connected sliding column 404 to move in the direction of the cylindrical housing 402, and at the same time, the spring 403 is gradually compressed. When the cylindrical rod 410 drives the fixedly connected connecting rod 2 408 to swing clockwise to a horizontal position under the restriction of the support plate 407, the connecting rod 2 408 and the connecting rod 1 406 swing to the maximum angle, and at this time the spring 403 is compressed to the minimum.

[0057] When the cylindrical rod 410 is manually lifted upward, all the above components perform recovery movement, and the recovery movement process moves in the opposite direction according to the above movement process. At this time, the spring 403 gradually recovers. When the spring 403 returns to a balanced state, all the above components return to their initial state. By providing the pick-and-place mechanism 4, when the staff needs to take or place confidential documents, they can first open the cabinet door, and then manually pull the cylindrical rod 410. The cylindrical rod 410 drives the second connecting rod 408 to rotate around the point of rotation connection with the support plate 407, so that the second connecting rod 408 drives the rotatably connected document placement box 409 to swing downward, thereby making it easier for the staff to take or place confidential documents, and documents high in the cabinet are easier to take or place. The staff does not need to spend more time and energy to complete these operations, thereby improving work efficiency.

[0058] Please refer to the above working process Figures 1 to 4 .

[0059] The following is the working process of the size adjustment mechanism 5 for adjusting the isolation plate 509 to accommodate different file sizes:

[0060] When in use, the rotating column 503 is driven by the internal motor to rotate counterclockwise, so that the multiple rotating blocks 508 set will slide along the symmetrically arranged sliding grooves 505 toward the two ends of the rotating column 503. At the same time, the rotating block 508 drives the sliding block 507 connected to the rotation to slide toward the two ends of the guide rod 506 under the restriction of the guide rod 506, and then the sliding block 507 drives the fixedly connected isolation plate 509 to move toward the two ends of the guide rod 506. At this time, the multiple isolation plates 509 that are relatively concentrated will gradually disperse, and the distance between the isolation plates 509 from the middle to the two ends will gradually increase, so that larger documents can be placed at the two ends and smaller documents can be placed in the middle, which is convenient for staff to search. As the rotating column 503 keeps rotating counterclockwise, when the outermost rotating block 508 slides along the sliding groove 505 to the end of the sliding groove 505 away from the sliding groove 1 504, the rotating block 508 drives the fixedly connected isolation plate 509 to disperse to the maximum through the sliding block 507;

[0061] When the rotating column 503 rotates clockwise, all the above components perform recovery movement, and the recovery movement process moves in the opposite direction according to the above movement process. When the second slide 505 drives the second rotating block 508 to move to the end of the second slide 505 close to the first slide 504, all the above components return to their initial state; through the size adjustment mechanism 5, when the staff needs to store confidential documents, the rotating column 503 can rotate continuously to make the second rotating block 508 slide along the second slide 505, and the second rotating block 508 drives the isolation plate 509 to move in the horizontal direction through the sliding block 507, so that the spacing between the multiple isolation plates 509 is gradually increased from the middle to the two ends. When the user places documents, thick documents are placed on both sides and thinner documents are placed in the middle. In this way, the user can flexibly organize and store documents according to actual needs and document sizes, improve the efficiency and convenience of document storage, and maximize the use of available space. The partitions can be moved and adjusted as needed to make full use of the internal space of the file cabinet and avoid space waste.

[0062] Please refer to the above working process Figures 5 to 8 .

[0063] Overview: Through the provision of the pick-and-place mechanism 4, when the staff needs to take or place confidential documents, they can manually pull the cylindrical rod 410, and the cylindrical rod 410 drives the second connecting rod 408 to rotate around the point of rotational connection with the support plate 407, so that the second connecting rod 408 drives the rotatably connected document placement box 409 to swing downward, thereby making it easier for the staff to take or place confidential documents. Moreover, since the documents at the top of the cabinet are easy to take or place, the staff does not need to spend more time and energy to complete these operations, thereby improving work efficiency. At the same time, through the provision of the size adjustment mechanism 5, when the staff needs to store confidential documents, The continuous rotation of the rotating column 503 causes the rotating block 2 508 to slide along the sliding groove 2 505. The rotating block 2 508 drives the isolation plate 509 to move in the horizontal direction through the sliding block 507, thereby increasing the distance between the multiple isolation plates 509, and thus enabling the filing cabinet to be freely adjusted according to files and folders of different sizes. In this way, users can flexibly organize and store files according to actual needs and file sizes, improve the efficiency and convenience of file storage, and maximize the use of available space. The partitions can be moved and adjusted as needed to make full use of the internal space of the filing cabinet and avoid space waste.
