Abstract
Description
Technical Field
[0001] This invention relates to the field of audit data confidentiality technology, and more specifically to a cabinet for storing audit data. Background Technology
[0002] Audit materials refer to all written records, data, documents, and reports related to the audit work that are collected, compiled, and organized during the audit process.
[0003] The audit materials include various financial regulations, policies, and systems formulated by the State Council, local people's governments, and audit institutions, which can be used as the audit basis; audit plans and work programs, audit working papers, investigation records, audit reports, audit decisions, and other materials prepared by the audit institutions; as well as various data and materials reflecting the basic situation and main problems of the audited entity, and evidence materials such as witness testimonies and verification records. Collecting and organizing audit materials is an important foundation for establishing audit files.
[0004] When auditors need to take audit materials out of the office, they need to place them in a secure case. The secure case is usually equipped with an anti-theft lock on the outside, so even if the secure case is lost, the anti-theft lock can prevent the loss of materials. However, relying on a single secure lock for protection has limited effectiveness. In addition to paper documents, audit materials also include various seals, so the bottom of the secure case is usually round or square. Modern secure cases cannot hold different seals in place, and seals are easily damaged when they move inside the case.
[0005] When the secure box falls, it vibrates upon impact, potentially opening the lock. This could cause data to scatter and damage internal documents, highlighting the urgent need for a secure audit data secure box. Summary of the Invention
[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a cabinet for storing audit data to solve the technical problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a cabinet for storing audit documents, comprising a secure outer shell, a secure outer cover movably connected to the top of the secure outer shell, a rotary combination lock fixedly connected to the side of the secure outer shell, the rotary combination lock locking the secure outer cover, a partition plate fixedly connected to the side of the secure outer shell that opens into the rotary combination lock, a connecting shaft fixedly connected to the top of the secure outer shell on the side away from the rotary combination lock, a secure inner cover movably connected to the side of the connecting shaft, a document security mechanism fixedly connected to the side of the partition plate away from the secure inner cover, a first stamp mechanism fixedly connected to the side of the secure outer shell away from the connecting shaft, and a second stamp mechanism fixedly connected to the other side of the secure outer shell away from the connecting shaft, and a triggering mechanism fixedly connected to the middle of the secure outer shell away from the connecting shaft;

The top of the magnetic plate is fixedly connected with a limited displacement plate. The bottom of the fixing block is provided with a limiting groove that matches the limited displacement plate.
[0009] In a preferred embodiment, a handle is fixedly connected to the side of the outer shell of the security box near the handle, and the handle is located at the center of the side of the outer shell of the security box. The bottom end of the inner cover of the security box contacts the bottom end of the outer cover of the security box, and the side of the inner cover of the security box is fixedly connected to the side of the document security mechanism.
[0010] In a preferred embodiment, a limiting cylinder is fixedly connected to the side of the displacement limiting plate away from the electromagnet, a fixing rod is provided on the side of the limiting cylinder away from the magnetic plate, a limiting spring is provided on the side of the fixing rod, and a clearance hole is provided inside the magnetic plate to allow the limiting rod to move.
[0011] In a preferred embodiment, an electronic combination lock is fixedly connected to the side of the fixing block. The top of the electronic combination lock is located below the bottom of the connecting block. After the electronic combination lock is correctly entered with a password, the electromagnet is energized and generates a magnetic repulsion force between it and the magnetic plate. The energization time of the electromagnet is five seconds.
[0012] In a preferred embodiment, the triggering mechanism includes a fixed outer cylinder for fixing, a fixed magnetic block is fixedly connected to the top of the fixed outer cylinder, a magnetic sliding plate is movably connected to the bottom of the fixed magnetic block, an insulating block is fixedly connected to the bottom of the magnetic sliding plate, a connecting guide plate is provided at the bottom of the insulating block, first wires are provided on both sides of the connecting guide plate, and a second wire is provided at the bottom of the first wires. When the connecting guide plate moves downward, it contacts the second wire.
[0013] In a preferred embodiment, a sealing plate is fixedly connected to the bottom end of the connecting guide plate, the sealing plate seals the inside of the fixed outer cylinder, a movable rod is fixedly connected to the bottom end of the sealing plate, a limiting arc plate is movably connected to the side of the movable rod, and the bottom end of the limiting arc plate is fixedly connected to the bottom end of the inside of the fixed outer cylinder.
[0014] In a preferred embodiment, the first stamp mechanism includes a first placement outer cylinder that can be fixed. A fixing shaft is fixedly connected to the top of the first placement outer cylinder, and a sealing cover is movably connected to the side of the fixing shaft. A locking piece is fixedly connected to the bottom of the sealing cover on the side away from the fixing shaft. A security lock is provided on the side of the first placement outer cylinder, and the locking piece corresponds to the position of the security lock.
[0015] In a preferred embodiment, the first outer cylinder has a limiting hole inside that matches the bottom of the circular stamp. The limiting hole of the circular stamp has a clearance hole that can accommodate the support spring. The side of the support spring has a limiting ball, and the bottom of the limiting ball contacts the bottom of the circular stamp.
[0016] In a preferred embodiment, the second stamp mechanism includes a second placement outer cylinder that can be fixed. The interior of the second placement outer cylinder is provided with a limiting square hole that is adapted to the bottom of the square stamp, and each of the four sides of the limiting square hole of the square stamp is provided with a support spring and a limiting ball.
[0017] The technical effects and advantages of this invention are as follows:
[0018] 1. In this invention, paper documents are placed under the inner cover of the security cover, and the displacement limiting plate is located inside the connecting block. At this time, the connecting block is fixed, which in turn fixes the inner cover of the security cover and the paper documents. When vibration occurs, the displacement limiting plate cannot move to the other side of the connecting block and be removed from the connecting block. The inner cover of the security cover is always fixed and locked. Rotating the combination lock will also lock the inner cover of the security cover, thus preventing damage to the paper documents.
[0019] 2. This invention includes a magnetic sliding plate, an insulating block, and a first wire. When vibration occurs, the magnetic sliding plate moves away from below the fixed magnetic block. As the magnetic sliding plate moves away, it causes the insulating block to move downwards. As the insulating block moves downwards, it causes the connecting guide plate to move. The connecting guide plate changes from connecting to the first wire to connecting to the second wire. At this time, the electromagnet is in a de-energized state and will not work, preventing the connecting block from being opened and thus preventing the document from falling.
[0020] 3. When the circular stamp is placed in the first placement outer cylinder, the circular stamp is placed downwards. At this time, the circular stamp will pass through the limiting ball and press the limiting ball into the first placement outer cylinder. After the bottom of the circular stamp passes through the limiting ball, the limiting ball is popped out by the support spring, thereby fixing the circular stamp. The square stamp can be fixed in the second placement outer cylinder, and the first placement outer cylinder and the square stamp can be locked together to protect the circular stamp and the square stamp.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The audit data storage cabinet involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Reference Figure 1 , Figure 2 as well as Figure 3 This invention provides a cabinet for storing audit documents, including a secure outer shell 1, a secure outer cover 2 movably connected to the top of the secure outer shell 1, a rotary combination lock 3 fixedly connected to the side of the secure outer shell 1, the rotary combination lock 3 locking the secure outer cover 2, a partition plate 5 fixedly connected to the side of the secure outer shell 1 that opens into the rotary combination lock 3, a connecting shaft 11 fixedly connected to the top of the secure outer shell 1 on the side away from the rotary combination lock 3, a secure inner cover 10 movably connected to the side of the connecting shaft 11, and a partition plate 5 fixedly connected to the side away from the secure inner cover 10. The document security mechanism 6 is provided. A first stamp mechanism 8 is fixedly connected to the side of the security box shell 1 away from the connecting shaft 11, and a second stamp mechanism 9 is fixedly connected to the other side of the security box shell 1 away from the connecting shaft 11. A trigger mechanism 7 is fixedly connected to the middle part of the security box shell 1 away from the connecting shaft 11. A handle 4 is fixedly connected to the side of the security box shell 1 near the handle 4, and the handle 4 is located at the center of the side of the security box shell 1. The bottom end of the inner security cover 10 is in contact with the bottom end of the outer security cover 2, and the side of the inner security cover 10 is fixedly connected to the side of the document security mechanism 6.
[0034] In this embodiment, the handle 4 facilitates carrying the entire device, ensuring its portability. The inner cover 10 can be locked by the document security mechanism 6 to secure the documents inside. The top of the inner cover 10 contacts the bottom of the outer cover 2 of the security box. Therefore, when the outer cover 2 of the security box is locked by rotating the combination lock 3, the inner cover 10 can be locked again, improving the security effect.
[0035] Reference Figure 3 , Figure 4 as well as Figure 5 The document security mechanism 6 includes a fixing block 601 fixedly connected to the side of the partition plate 5. A connecting block 602 is located at the top of the fixing block 601. The fixing block 601 and the connecting block 602 are separate. An occlusion groove is provided inside the fixing block 601, allowing the magnetic plate 605 to move. An electromagnet 604 is located on the side of the magnetic plate 605, and the side of the electromagnet 604 is fixedly connected to the interior of the fixing block 601. A limiting displacement plate 606 is fixedly connected to the top of the magnetic plate 605. A limiting groove adapted to the limiting displacement plate 606 is located at the bottom of the fixing block 601. The limiting displacement plate 606 is located at a distance from the top of the magnetic plate 605. A limiting cylinder 609 is fixedly connected to the side of the electromagnet 604. A fixing rod 610 is provided on the side of the limiting cylinder 609 away from the magnetic plate 605. A limiting spring 608 is provided on the side of the fixing rod 610. An isolation hole is opened inside the magnetic plate 605 to allow the limiting rod 607 to move. An electronic combination lock 603 is fixedly connected to the side of the fixing block 601. The top of the electronic combination lock 603 is located below the bottom of the connecting block 602. After the electronic combination lock 603 correctly enters the password, the electromagnet 604 is energized and generates a magnetic repulsion force between it and the magnetic plate 605. The energization time of the electromagnet 604 is five seconds.
[0036] In this embodiment, after the electromagnet 604 and the magnetic plate 605 generate magnetic repulsion, the magnetic plate 605 drives the displacement limiting plate 606 to move and compress the limiting spring 608. At this time, the connecting block 602 contacts the fixing block 601, and the displacement limiting plate 606 enters the connecting block 602 to lock the connecting block 602. The connecting block 602 locks the inner cover 10. When the electromagnet 604 is energized, the side of the magnetic plate 605 is provided with a limiting rod 607 and a limiting cylinder 609, which increases the friction when the magnetic plate 605 moves, and also has the elasticity of the limiting spring 608, preventing the magnetic plate 605 from moving when it is vibrated, thereby unlocking the connecting block 602 and improving the security effect. When the overall power is insufficient, the electromagnet 604 cannot be started and will not unlock the connecting block 602, preventing the ordinary electromagnetic lock from automatically unlocking when it is taken away by others.
[0037] Reference Figure 6 and Figure 7The triggering mechanism 7 includes a fixed outer cylinder 701 for fixing. A fixed magnetic block 702 is fixedly connected to the top of the fixed outer cylinder 701. A magnetic moving plate 703 is movably connected to the bottom of the fixed magnetic block 702. An insulating block 704 is fixedly connected to the bottom of the magnetic moving plate 703. A connecting guide plate 705 is provided at the bottom of the insulating block 704. A first wire 709 is provided on both sides of the connecting guide plate 705. A second wire 710 is provided at the bottom of the first wire 709. When the connecting guide plate 705 moves downward, it contacts the second wire 710. A sealing plate 706 is fixedly connected to the bottom of the connecting guide plate 705. The sealing plate 706 seals the inside of the fixed outer cylinder 701. A moving rod 707 is fixedly connected to the bottom of the sealing plate 706. A limiting arc plate 708 is movably connected to the side of the moving rod 707. The bottom of the limiting arc plate 708 is fixedly connected to the bottom of the inside of the fixed outer cylinder 701.
[0038] In this embodiment, upon falling, the magnetic moving plate 703 will fall from below the fixed magnetic block 702 after vibration. At this time, the insulating block 704 will drive the connecting guide plate 705 to move downwards. The connecting guide plate 705 will change the connection of the first wire 709 to the connection of the second wire 710. After the second wire 710 is connected, the electromagnet 604 will be de-energized to prevent the electromagnet 604 from being damaged by vibration and erroneously starting, thus causing data loss. When the connecting guide plate 705 moves, it will drive the sealing plate 706 to move downwards and compress the gas below the sealing plate 706. Therefore, after the vibration stops, the compressed gas below the sealing plate 706 will reset, resetting the connecting guide plate 705 and the fixed magnetic block 702, allowing the electromagnet 604 to work normally. In addition, it should be noted that... Figure 6 Inside, the bottom end of the connecting guide plate 705 is not connected to the top of the sealing plate 706 for ease of display.
[0039] Reference Figure 8 , Figure 9 as well as Figure 10The first seal mechanism 8 includes a first placement outer cylinder 801 that can be fixed. A fixing shaft 802 is fixedly connected to the top of the first placement outer cylinder 801. A sealing cover plate 803 is movably connected to the side of the fixing shaft 802. A locking piece 804 is fixedly connected to the bottom of the sealing cover plate 803 away from the fixing shaft 802. A security lock 805 is provided on the side of the first placement outer cylinder 801. The locking piece 804 and the security lock 805 are positioned correspondingly. The interior of the first placement outer cylinder 801 has a limiting opening adapted to the bottom of the circular seal 808. The circular stamp 808 has a limiting hole that can accommodate the support spring 806. The support spring 806 has a limiting ball 807 on its side. The bottom end of the limiting ball 807 contacts the bottom end of the circular stamp 808. The second stamp mechanism 9 includes a second placement outer cylinder 901 that can be fixed. The second placement outer cylinder 901 has a limiting square hole that matches the bottom of the square stamp 902. The four sides of the limiting square hole of the square stamp 902 are provided with support spring 806 and limiting ball 807.
[0040] In this embodiment, the seals include two types: a round seal 808 and a square seal 902. This application can adapt these two different seals through the first seal mechanism 8 and the second seal mechanism 9. When the round seal 808 and the square seal 902 enter the first placement outer cylinder 801 and the second placement outer cylinder 901, the limiting ball 807 can fix them to prevent them from shaking, thereby ensuring that the round seal 808 and the square seal 902 will not be easily damaged.
[0041] The working principle of the present invention is as follows: When placing audit materials, both the outer cover 2 and the inner cover 10 of the confidential box are opened, and the first stamp mechanism 8 and the second stamp mechanism 9 are also opened. The paper materials are placed below the position of the inner cover 10, the round stamp 808 is placed in the first stamp mechanism 8, and the square stamp 902 is placed in the second placement outer cylinder 901.
[0042] When the circular stamp 808 is placed inside the first placement outer cylinder 801, the circular stamp 808 moves downward. At this time, the circular stamp 808 passes through the limiting ball 807 and presses the limiting ball 807 into the first placement outer cylinder 801. After the bottom of the circular stamp 808 passes the limiting ball 807, the limiting ball 807 is popped out by the support spring 806, thereby fixing the bottom of the circular stamp 808 to prevent it from shaking and being damaged. After rotating the sealing cover plate 803, the locking plate 804 and the security lock 805 are aligned. The security lock 805 locks the locking plate 804. The square stamp 902 is fixed inside the second placement outer cylinder 901 in the same way. At this time, the first stamp mechanism 8 and the second stamp mechanism 9 cannot be opened without a key, achieving a good security effect.
[0043] After the paper documents are placed, the correct password is entered through the electronic combination lock 603. When the electromagnet 604 is energized, a magnetic repulsion force is generated between it and the magnetic plate 605. The magnetic plate 605 drives the displacement limiting plate 606 to move and compress the limiting spring 608. At this time, the connecting block 602 contacts the fixing block 601, the electromagnet 604 is de-energized, the displacement limiting plate 606 is reset, and the displacement limiting plate 606 enters the connecting block 602, fixing the position of the connecting block 602. The outer shell 1 of the security box contacts the outer cover 2 of the security box, and the combination lock 3 is turned to lock it. The entire box can be taken away by the handle 4.
[0044] When it falls, the whole thing will vibrate. When the vibration is large, the magnetic moving plate 703 will move away from the fixed magnetic block 702. When the magnetic moving plate 703 moves away from the fixed magnetic block 702, it will drive the insulating block 704 to move. The insulating block 704 will drive the connecting guide plate 705 to move. When the connecting guide plate 705 moves, it will drive the sealing plate 706 to move downward and compress the gas under the sealing plate 706. When the connecting guide plate 705 moves downward, it will change the connection of the first wire 709 to the connection of the second wire 710. After the second wire 710 is connected, the electromagnet 604 will be de-energized to prevent the electromagnet 604 from being damaged by vibration and starting incorrectly.
[0045] If the electromagnet 604 is low on power, it will not be able to start. The displacement limiting plate 606 will fix the connecting block 602, preventing the current electromagnetic lock from failing to lock when the power is off, which could lead to data leakage. In addition, the magnetic plate 605 and the displacement limiting plate 606 are relatively lightweight, and the side of the magnetic plate 605 is limited by the limiting rod 607 and the limiting cylinder 609, resulting in high friction. Therefore, when the whole unit is dropped and vibrates, the displacement limiting plate 606 will not be able to move out of the connecting block 602 and compress the limiting spring 608.
[0046] In conclusion, the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
