[0029] In addition, the described features, structures or characteristics may be combined in one or more example embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0030] like Figure 1-Figure 9 As shown, an office briefcase of the present invention comprises an aluminum briefcase 1, wherein two password devices 2 are arranged at the top of one side of the outer wall of the aluminum briefcase 1, and two key devices 3 are arranged at the bottom of the same side of the outer wall of the aluminum briefcase 1. The password devices 2 and the key devices 3 are used to simultaneously protect the internal documents of the aluminum briefcase 1. The aluminum briefcase 1 can only be opened when the password devices 2 and the key devices 3 are passed at the same time, thereby improving the protection effect of the documents.

[0031] The password device 2 includes a first shell 4 fixedly connected to the top of one side of the outer wall of the aluminum handbag 1, three limiting circular grooves 5 are opened inside the first shell 4, a cylindrical through groove 6 runs through the inside of the first shell 4, a rotating ring 7 with an L-shaped cross-section is rotatably connected inside the limiting circular groove 5, a rotating disk 8 is arranged inside the rotating ring 7, a hollow column 9 is fixedly connected to one side of the outer wall of the rotating disk 8, the hollow column 9 is slidably connected to the cylindrical through groove 6, a placement groove 10 is opened on the side of the rotating disk 8 away from the hollow column 9, the placement groove 10 is communicated with the inside of the hollow column 9, a transmission column 11 is slidably connected inside the placement groove 10, a transmission rod 12 runs through and is fixedly connected to the transmission column 11, and the transmission rod 12 is slidably connected to the hollow column 9. The column 9 is slidably connected, the transmission rod 12 passes through both ends of the cylindrical through groove 6, one end of the transmission rod 12 is fixedly connected to a first limiting disc 13, the other end of the transmission rod 12 is fixedly connected to a second limiting disc 14, a first spring 15 is fixedly connected between the second limiting disc 14 and the outer wall of the first shell 4, the outer circumference of the hollow column 9 is fixedly connected to a gear 16, the outer circumference of the hollow column 9 is fixedly connected to a chuck 17 at one end away from the gear 16, an entrance 18 is opened on one side of the outer wall of the chuck 17, a clamping column 19 is provided inside the chuck 17, and the end of the clamping column 19 away from the chuck 17 is fixedly connected to a support rod 20, by rotating the rotating ring 7, the rotating ring 7 drives the rotating disc 8 to rotate, and the rotating disc 8 drives the hollow column 9 to rotate, and the hollow The core column 9 drives the gear 16 and the chuck 17 to rotate. When the three rotating rings 7 are rotated to the correct position, the three entrances 18 are located on the same side, and the card column 19 is next to the entrance 18. At this time, the aluminum handbag 1 is opened, and the card column 19 will pass through the entrance 18 and move out of the chuck 17. The aluminum handbag 1 can drive the first shell 4. When the password needs to be changed, the second limit disc 14 is pressed. The second limit disc 14 drives the first spring 15 to compress and drives the transmission rod 12 to slide. The transmission rod 12 drives the transmission column 11 to slide in the placement groove 10. The transmission column 11 drives the rotating disk 8 to separate from the rotating ring 7. At this time, the rotating ring 7 is rotated until the number displayed on the rotating ring 7 is the required number, and then the second limit disc 14 is released. , the first spring 15 drives the second limit disc 14 to reset, the second limit disc 14 drives the transmission rod 12, the transmission rod 12 drives the first limit disc 13 and the transmission column 11, the transmission column 11 and the first limit disc 13 drive the hollow column 9 to move, and the hollow column 9 drives the rotating disk 8 back to the rotating ring 7. This password device 2 only needs to press the second limit disc 14 to change the password, and the operation is simple. At the same time, the six rotating rings 7 need to be rotated to the correct position at the same time to open the aluminum handbag 1. Since it is not a traditional password lock structure, the chuck 17 and the chuck column 19 are stuck in an invisible place inside the first shell 4, so that the password cannot be inferred from the sound or the gap on both sides of the rotating ring 7, thereby improving the safety of this aluminum handbag 1.

[0032] Specifically, the key device 3 includes a second shell 21 fixedly connected to the bottom of one side of the outer wall of the aluminum handbag 1, the second shell 21 and the first shell 4 are both provided with a T-shaped groove 22, a T-shaped rack 23 is slidably connected inside the T-shaped groove 22, a first cylindrical hole 24 is provided inside the shell, a second cylindrical hole 25 is provided in the middle of the first cylindrical hole 24, an outer toothed ring 26 is provided inside the second cylindrical hole 25, the outer toothed ring 26 is meshed with the T-shaped rack 23, and a circular toothed ring 26 is fixedly connected inside the outer toothed ring 26. The cylinder 27 is rotatably connected to the first cylindrical hole 24. The first shell 4 has three first cylindrical grooves 28. The first shell 4 and the cylinder 27 have three second cylindrical grooves 29. The first cylindrical groove 28 has a second spring 30 fixedly connected therein. The top of the second spring 30 is fixedly connected to a sliding plate 31. The top of the sliding plate 31 is fixedly connected to a first sliding column 32. The first sliding column 32 is slidably connected to the second cylindrical hole 25. The top of the first sliding column 32 is fitted with a second sliding column 33. The second slide post 33 is slidably connected with the second cylindrical hole 25, and the support rod 20 is fixedly connected with the top of the second shell 21. By inserting the key into the cylindrical body 27, the key drives the second slide post 33 to descend, and the second slide post 33 drives the first slide post 32 to slide downward in the second cylindrical hole 25. The first slide post 32 drives the sliding plate 31 to slide in the first cylindrical hole 24, and the sliding plate 31 drives the second spring 30 to compress. Then the key is turned, and the key drives the cylindrical body 27 to rotate. At this time, the first slide post 32 and the second slide post 33 are connected. 3 is separated, the cylinder 27 drives the outer toothed ring 26 to rotate, and the outer toothed ring 26 drives the T-shaped rack 23 to slide in the T-shaped groove 22. When the T-shaped rack 23 slides from the first shell 4 to the second shell 21, the T-shaped rack 23 can no longer connect the first shell 4 and the second shell 21 into a whole. The key device 3 is used as a prerequisite for operating the password device 2, so that if the key device 3 is not opened, the password device 2 will not be able to operate, and only the key cannot open the aluminum handbag 1, thereby improving the safety of the aluminum handbag 1.

[0033] Specifically, the first slide column 32 is a magnet material component, and the second slide column 33 is an iron material component. Since the first slide column 32 is a magnet material component and the second slide column 33 is an iron material component, under normal circumstances, the first slide column 32 will absorb the second slide column 33 to prevent the second slide column 33 from falling.

[0034] Specifically, a transverse sliding groove 34 is opened inside the first shell 4, and an L-shaped rod 35 is slidably connected inside the transverse sliding groove 34. The end of the L-shaped rod 35 away from the T-shaped rack 23 is fixedly connected to a third spring 36. The third spring 36 is fixedly connected to the inside of the first shell 4. Three clamping strips 37 are fixedly connected to the bottom of the L-shaped rod 35. The clamping strips 37 are meshed with the gear 16. When the T-shaped rack 23 slides out of the first shell 4, the third spring 36 drives the L-shaped rod 35 to slide through the elastic force, and the L-shaped rod 35 drives the clamping strip 37 to separate from the gear 16. At this time, the gear 16 can rotate, so that if the key device 3 is not opened, the rotating ring 7 cannot be rotated, thereby improving the safety of the aluminum handbag 1.

[0035] Specifically, the inner circumference of the rotating ring 7 is provided with a plurality of wave crests 38 with an angle of 30°, the outer circumference of the rotating disk 8 is provided with a plurality of valleys 39 with an angle of 30°, and the outer circumference of the rotating ring 7 is equidistantly engraved with numbers 0 to 9. Through the wave crests 38 and valleys 39, when the wave crests 38 and valleys 39 cooperate, the rotating ring 7 can drive the rotating disk 8, thereby facilitating changing the password.

[0036] Specifically, an L-shaped groove 40 is opened inside the first shell 4, and a second L-shaped rod 41 is slidably connected inside the L-shaped groove 40. The second L-shaped rod 41 is fixedly connected to the transmission rod 12. When the T-shaped rack 23 presses against the first L-shaped rod 35, the transmission rod 12 cannot push the second L-shaped rod 41 to slide in the L-shaped groove 40. At this time, the secret cannot be changed. The password can only be changed when the key device 3 is opened.

[0037] The specific implementation method is as follows: when the aluminum handbag 1 needs to be opened, the key must first be inserted into the cylinder 27 and then rotated. When the T-shaped rack 23 is retracted from the first shell 4 into the second shell 21, the clamping strip 37 will be separated from the gear 16. Only then can the rotating ring 7 be rotated. Then, after all six rotating rings 7 in the two password devices 2 are rotated to the correct position, the chuck 17 will not be blocked by the clamping column 19 when it moves. The clamping column 19 can be moved out of the entrance 18 on the chuck 17. Only then can the aluminum handbag 1 be opened. The key device 3 must be opened with a specific key first, and then the six rotating rings 7 can be rotated to the correct position to open the aluminum handbag 1. The aluminum handbag 1 cannot be opened if the sequence and operation are wrong.

[0038] To open the aluminum handbag 1, the key device 3 needs to be opened with a key, and then the rotating ring 7 in the password device 2 is rotated to an accurate position, so that the first shell 4 and the second shell 21 are no longer connected by parts, and then the aluminum handbag 1 can be opened and important documents inside can be taken out, so that the requirements for opening the aluminum handbag 1 are improved, thereby improving the security of the aluminum handbag 1;

[0039] The L-shaped rod 35 is pushed by the T-shaped rack 23 in the key device 3, and the L-shaped rod 35 drives the clamping strip 37 to mesh with the gear 16. At this time, the gear 16 cannot rotate, so that the password device 2 cannot be operated without opening the key device 3. The user only needs to keep the key safe. Even if others know the password, they cannot operate the password device 2, thereby improving the security of the aluminum handbag 1.

[0040] The relative position between the first shell 4 and the second shell 21 is fixed by the cooperation between the card column 19 and the card disk 17 in the password device 2, and the card disk 17 cannot be seen from the gap between the rotating ring 7 and the first shell 4. At the same time, the password device 2 is not like the password lock structure in the prior art. The sound emitted by the rotating ring 7 when rotating is the same, so that outsiders cannot judge the composition of the password, thereby improving the security of the aluminum handbag 1. This embodiment specifically solves the problem that when the existing password lock is rotating, it is easy to judge the password through sound or by observing the gaps on both sides of the rotating ring, or others know the password and can take away or copy and photograph the financial data without consent, etc., and the security needs to be improved. Therefore, there is an urgent need for an office handbag with high security, which cannot judge the password through sound or the gaps on both sides of the rotating ring, and prevents someone from getting the files but does not want the financial staff to know.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
