By setting a plurality of cavities, and each cavity adopts a different lock body, the importance of the files can be effectively classified and different locking methods can be adopted according to the importance of the files;

[0039] The transverse plate 7 is provided with a first placement groove 701 and a second placement groove 702. The first placement groove 701 is located at one side of the first lock body 10 and opens upwards and is used to place the first rotating rod 14. The second placement groove 702 is located at one side of the third lock body 13 and opens downwards and is used to place the second rotating rod 15. The first placement groove and the second placement groove are provided to adapt the working mode and unlocking mode of the first lock body and the third lock body.

[0040] The upper cavity 8 and the lower cavity 9 are respectively connected with a first clamping rod 801 and a second clamping rod 901, both of which are L-shaped, and the first rotating rod 14 is clamped on the first clamping rod 801 to lock the upper cavity 8, and the second rotating rod 15 is clamped on the second clamping rod 901 to lock the lower cavity 9;

[0041] The first lock body 10 and the third lock body 13 are respectively provided with a first key 1001 and a second key 1301. The head of the first key 1001 is made of a material that can be attracted by a magnet and the end of the first key 1001 is made of a non-conductive material. The end of the second key 1301 is provided with an insertion port 1302 for inserting the head of the first key 1001 and a magnet 1303 is provided on one side of the insertion port 1302. The magnet 1303 is used to absorb the head of the first key 1001. The second key can be inserted into the third lock body to unlock the door only when the second key is used in conjunction with the first key. Such a design not only increases the safety performance, but also allows the allocation of keys to be selected according to different job identities, thereby realizing the management of authority.

[0042] A contact 703 is provided on one side of the first placement slot 701, the first rotating rod 14 is connected to the battery in the first lock body 10 and a power supply contact 1401 is provided on one side of the bottom of the first rotating rod 14, and the power supply contact 1401 contacts the contact 703 for power supply;

[0043] The limiting device 16 is composed of an upper and lower sliding rod 1601 and an upper push rod 1602. The upper and lower sliding rod 1601 is slidably located in the vertical plate 4 and the bottom end of the upper and lower sliding rod 1601 passes through the horizontal plate 7 and extends into the lower cavity 9. An opening groove is provided in the lower cavity 9 for manually lifting the upper and lower sliding rod 1601. The bottom of the upper push rod 1602 is connected to the upper and lower sliding rod 1601 and the top of the upper push rod 1602 extends to the outside of the top of the cabinet 1. A notch 1603 is provided on one side below the upper and lower sliding rod 1601 and a block 1604 is fixedly connected to the other side below the upper and lower sliding rod 1601. The block 1604 is located in the horizontal plate 7 and moves up and down, and the distance that the upper and lower sliding rod 1601 moves up and down is the distance that the block 1604 moves up and down in the horizontal plate 7. The limiting device is used to limit the second lock body, and the limiting device must be opened in the lower cavity to further ensure the layered superposition of permissions.

[0044] The cross plate 7 is also provided with a locking device 17, which includes a slide groove 1701 and a slide bar 1702. The slide groove 1701 is fixed to the top of the inner cavity of the cross plate 7, and the slide bar 1702 is slidably connected to the slide groove 1701. One side of the slide bar 1702 is provided with an electromagnet 1703 fixedly connected to the top of the inner cavity of the cross plate 7, and the electromagnet 1703 is electrically connected to the contact 703. A spring 1704 is connected between the slide bar 1702 and the electromagnet 1703. The slide bar 1702 is made of a material that can be attracted by a magnet and the suction force of the electromagnet 1703 on the slide bar 1702 is greater than the force of the spring 1704 when compressed. The end of the slide bar 1702 is arc-shaped and the slide bar 1702 is inserted into the notch 1603. The locking device is used to lock the limit device, so that when the limit device is unlocked, the locking device needs to be unlocked first, so as to further increase safety.

[0045] The second lock body 12 is provided with a third rotating rod 1201, which is stuck in the rear cavity 5 to lock the rear storage cavity 11. The third rotating rod 1201 and the card block 1604 are in a close fit state. The close fit state between the third rotating rod and the card block can ensure that the third rotating rod cannot be unlocked when the card block is not moved.

[0046] For example:

[0047] The unlocking method of the upper cavity 8 is to insert the first key 1001 into the first lock body 10. Since the first clamping rod 801 clamps the first rotating rod 14, the unlocking direction can only be clockwise. The first key 1001 is rotated clockwise, so that the lock core in the first lock body 10 rotates and drives the first rotating rod 14 to rotate clockwise and enter the first placement groove 701. At this time, the first rotating rod 14 will not clamp the first clamping rod 801, and the upper cavity 8 can be opened by opening the door upwards.

[0048] The unlocking method of the lower cavity 9 is to keep the upper cavity 8 in the open state, return the first key 1001 to its original position and pull it out. At this time, the first rotating rod 14 will also return to its original position, but because the upper cavity 8 is in the open state, there is no first clamping rod 801 to clamp the first rotating rod 14. Then, when the first key 1001 is pulled out, the head of the first key 1001 is inserted into the insertion port 1302 at the end of the second key 1301 and is fixed by the magnet 1303, thereby realizing the combination of the first key 1001 and the second key 1301. The combined key is inserted into the first lock body 10 and inserted to the bottom, at which time the first key 1001 is located in the first lock body 10, and the second key 1301 is located in the third lock body 13, and then the combined key is turned counterclockwise, at which time the first rotating rod 14 can rotate counterclockwise because it is not stuck by the first clamping rod 801, and the second rotating rod 15 will also rotate counterclockwise and enter the second placement groove 702, at which time the second rotating rod 15 will not be stuck by the second clamping rod 901, and the lower cavity 9 can be opened by opening the door downward;

[0049] The unlocking method of the rear storage cavity 11 is that since the third rotating rod 1201 and the card block 1604 are in a fitted state, when the key is inserted into the second lock body 12 and rotated to unlock, it will be stuck by the card block 1604, so that the third rotating rod 1201 cannot rotate clockwise or counterclockwise. Therefore, it is necessary to insert the first key 1001 into the first lock body 10 and rotate it clockwise when both the upper cavity 8 and the lower cavity 9 are opened. At this time, the first rotating rod 14 enters the first placement groove 701 and makes the power supply contact 1401 on the first rotating rod 14 contact with the contact 703 in the first placement groove 701 and Power is supplied, so that the electromagnet 1703 is energized and generates magnetic force to suck the slide bar 1702 out of the notch 1603, so that the upper and lower slide bars 1601 can slide up and down. At this time, the upper and lower slide bars 1601 are pushed upward through the opening grooves provided in the lower cavity 9 for manually lifting the upper and lower slide bars 1601, so that the block 1604 moves up and is no longer in contact with the third rotating rod 1201, so that the second lock body 12 can drive the third rotating rod 1201 to rotate clockwise or counterclockwise so that it is no longer stuck in the rear cavity 5, thereby completing the unlocking of the rear storage cavity 11, so that the rear storage cavity 11 can be pulled out;

[0050] The rear storage chamber 11 is locked, the second lock body 12 drives the third rotating rod 1201 to return to its position, and then the first key 1001 is rotated to make the first rotating rod 14 leave the first placement slot 701 so that the electromagnet 1703 is powered off, and then the upper push rod 1602 is pressed down to make the clamping block 1604 fit with the third rotating rod 1201 again. At this time, the spring 1704 will push the sliding rod 1702 into the notch 1603 to achieve fixed limit, thereby achieving the locking of the rear storage chamber 11 and the locking of the lower cavity 9 and the upper cavity 8. It can be obtained from the above-mentioned method for unlocking the lower cavity 9 that the second rotating rod 15 is rotated in the opposite direction to achieve the re-engagement of the second clamping rod 901, thereby re-locking the lower cavity 9. Similarly, it can be obtained from the method for unlocking the upper cavity 8 that the reverse operation is performed to lock the upper cavity 8.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

Therefore, it is necessary to insert the first key (1001) into the first lock body (10) and rotate it clockwise when both the upper cavity (8) and the lower cavity (9) are opened. At this time, the first rotating rod (14) enters the first placement groove (701) and the power supply contact (1401) on the first rotating rod (14) is aligned with the first placement groove (701). The contact (703) contacts and supplies power, thereby causing the electromagnet (1703) to be energized and generate magnetic force to suck the slide bar (1702) out of the notch (1603), so that the upper and lower slide bars (1601) can slide up and down. At this time, the upper and lower slide bars (1601) are pushed upward through the opening groove provided in the lower cavity (9) for manually lifting the upper and lower slide bars (1601), so that the blocking block (1604) moves up and no longer fits with the third rotating rod (1201), so that the second lock body (12) can drive the third rotating rod (1201) to rotate clockwise or counterclockwise so that it is no longer stuck in the rear cavity (5).

2. A working method of a financial accounting information management device, used to implement the working method of the financial accounting information management device according to claim 1, characterized in that: The invention relates to an unlocking method comprising an upper cavity (8), a lower cavity (9) and a rear storage cavity (11), which specifically comprises: The method for unlocking the upper cavity (8) comprises inserting the first key (1001) into the first lock body (10), and rotating the first key (1001) in a clockwise direction, so that the first rotating rod (14) will not be stuck on the first locking rod (801), and the upper cavity (8) can be opened by opening the door upwards; The method for unlocking the lower cavity (9) comprises: after opening the upper cavity (8), the upper cavity (8) is kept in the open state, the first key (1001) and the second key (1301) are combined, and then the combined key is inserted from the first lock body (10) to the bottom, and the combined key is rotated counterclockwise, so that the second rotating rod (15) will not be stuck on the second locking rod (901), and the lower cavity (9) can be opened by opening the door downward; The method for unlocking the rear storage cavity (11) comprises the following steps: when the upper cavity (8) and the lower cavity (9) are both opened, the first key (1001) is inserted into the first lock body (10) and rotated clockwise, and then the upper and lower sliding rods (1601) are pushed upward through an opening groove provided in the lower cavity (9) for manually lifting the upper and lower sliding rods (1601), so that the blocking block (1604) moves upward and no longer fits with the third rotating rod (1201), thereby allowing the second lock body (12) to drive the third rotating rod (1201) to rotate clockwise or counterclockwise so that it is no longer stuck in the rear cavity (5), thereby completing the unlocking of the rear storage cavity (11), and the rear storage cavity (11) can be pulled out.

3. The working method of a financial accounting information management device according to claim 2, characterized in that: The invention comprises a method for locking an upper cavity (8), a lower cavity (9) and a rear storage cavity (11), specifically comprising: The rear storage chamber (11) is locked, the second lock body (12) drives the third rotating rod (1201) to return to its original position, then the first key (1001) is turned to return the first rotating rod (14), and then the upper push rod (1602) is pressed down, thereby achieving locking of the rear storage chamber (11); To lock the lower cavity (9) and the upper cavity (8), the second rotating rod (15) is rotated in the opposite direction to re-engage the second locking rod (901), thereby re-locking the lower cavity (9). Similarly, the first rotating rod (14) is rotated in the opposite direction to re-engage the first locking rod (801), thereby locking the upper cavity (8).
