[0044] The present invention provides Figure 1 The key cabinet with dual protection function shown in the figure includes a cabinet body 1 and a cabinet door 2 hinged on the cabinet body 1. The keys are placed in the cabinet body 1 for centralized management. The cabinet door 2 can be set as a transparent acrylic plate, which is selected according to actual needs and will not be described in detail here.

[0045] Reference Figure 1 and Figure 4 As shown in the figure, a door lock device 3 is provided on the cabinet door 2, and the door lock device 3 includes a password input area 301, a keyhole 302 and a fingerprint recognition area 303. The password input area 301, the keyhole 302 and the fingerprint recognition area 303 respectively have three unlocking methods: password recognition, mechanical key and fingerprint recognition. In order to improve the security level, an unlocking method is set that requires at least two or three successful identifications at the same time before the cabinet door 2 can be opened.

[0046] Among them, password recognition, mechanical keys and fingerprint recognition are all common existing technologies and will not be described in detail here.

[0047] In the present invention, a fixing frame 16 is fixedly connected to the cabinet door 2 , and the fixing frame 16 surrounds the outer side of the door lock device 3 . A sliding cover 12 is slidably provided on the outer side of the fixing frame 16 .

[0048] When the door lock device 3 needs to be used to open the key cabinet, the operator slides the sliding cover 12 to open the fixed frame 16, making it easier to use the password input area 301, the key hole 302 and the fingerprint recognition area 303; after use, the control sliding cover 12 is reset and the fixed frame 16 is closed to protect the door lock device 3, preventing the password input area 301, the key hole 302 and the fingerprint recognition area 303 from being affected by dust, thereby extending the service life.

[0049] refer to Figure 3 and Figure 4 As shown in , considering that sweat may appear on human fingerprints, especially in summer and other conditions, it is easy to leave marks on the password input area 301 and the fingerprint recognition area 303, especially after multiple uses, these marks may accumulate and form obvious fingerprint imprints, which may be used by outsiders to guess the password, especially since there are many keys placed in the cabinet 1. In order to ensure the safety of the key cabinet, a wiping device 4 for cleaning the door lock device 3 is provided inside the fixed frame 16. The wiping device 4 includes a liquid box 401 and absorbent cotton 402, wherein the absorbent cotton 402 is close to the door lock device 3, and the interior of the liquid box 401 can be injected with a cleaning liquid, such as anhydrous alcohol, etc., and a through hole (not shown in the figure) is provided on one side of the liquid box 401 close to the absorbent cotton 402, so that the cleaning liquid can penetrate into the absorbent cotton 402, which is convenient for wiping the door lock device 3, and the sliding cover 12 can drive the wiping device 4 to move synchronously. The wiping device 4 is provided to wipe and clean the door lock device 3 after use to prevent fingerprint marks from being left, while ensuring the hygiene of the door lock device 3.

[0050] In addition, a liquid injection tube and other structures are provided on the liquid box 401 to facilitate the injection of cleaning liquid into the interior of the liquid box 401 .

[0051] refer to Figures 3 to 5 As shown in , considering that when the operator slides the sliding cover 12 to open the fixed frame 16, if the door lock device 3 is wiped, the password input area 301 and the fingerprint recognition area 303 are in a wet state, which may easily lead to unlocking failure, and will also increase the wear of the absorbent cotton 402, resulting in waste of cleaning liquid. In order to improve the use efficiency, a slide groove 6 is provided on the inner walls of the upper and lower ends of the fixed frame 16, and the interior of the slide groove 6 utilizes a guide mechanism to form a first sliding area 10 and a second sliding area 11, wherein the first sliding area 10 is close to the door lock device 3, and the second sliding area 11 is away from the door lock device 3.

[0052] When the operator opens the sliding cover 12, the sliding cover 12 drives the wiping device 4 to move along the trajectory of the second sliding area 11. The wiping device 4 does not contact the door lock device 3, and thus does not wipe the door lock device 3, thereby preventing the password input area 301 and the fingerprint recognition area 303 from being in a wet state before unlocking, causing unlocking failure, reducing the wear of the absorbent cotton 402, and avoiding waste of cleaning fluid.

[0053] After unlocking, when the sliding cover 12 is closed, the sliding cover 12 drives the wiping device 4 to move along the track of the first sliding area 10, and the wiping device 4 contacts the door lock device 3. The wiping device 4 can wipe the password input area 301 and the fingerprint recognition area 303 after use.

[0054] The present invention guides the position of the wiping device 4 during movement by providing structures such as the first sliding area 10 and the second sliding area 11, thereby preventing the password input area 301 and the fingerprint recognition area 303 from being in a wet state before unlocking, thereby preventing the unlocking failure caused by the wet state, reducing the wear of the absorbent cotton 402, and avoiding the waste of cleaning liquid.

[0055] Reference Figure 6 As shown in the figure, in the specific setting, the guide mechanism includes a partition 7, a first elastic strip 8 and a second elastic strip 9. The partition 7 is distributed along the length direction of the slide groove 6. The partition 7 is located between the first elastic strip 8 and the second elastic strip 9. The partition 7 is fixedly connected to the inner wall of the slide groove 6. The end of the first elastic strip 8 away from the partition 7 is inclined toward the door lock device 3, and the end of the second elastic strip 9 away from the partition 7 is inclined toward the door lock device 3.

[0056] A sliding mechanism cooperating with the guide mechanism is provided inside the slide groove 6. The sliding mechanism includes a slider 5. The slider 5 is fixedly connected to the wiping device 4, and the width of the slider 5 is smaller than the width of the first sliding area 10 and the second sliding area 11. The slider 5 can slide inside the first sliding area 10 or the second sliding area 11. In addition, structures such as ball bearings can be provided on the outside of the slider 5 to reduce the friction of the slider 5 when moving.

[0057] Reference Figure 6 As shown in , when the slider 5 slides from right to left inside the slide groove 6, under the guidance of the first elastic strip 8, the slider 5 will enter the inside of the second sliding area 11, thereby sliding from right to left inside the second sliding area 11. When it moves to the second elastic strip 9, it will squeeze the left end of the second elastic strip 9 to swing, which will not affect the passage of the slider 5; when the slider 5 slides from left to right inside the slide groove 6, under the guidance of the second elastic strip 9, the slider 5 will enter the inside of the first sliding area 10, thereby sliding from left to right inside the second sliding area 11. When it moves to the first elastic strip 8, it will squeeze the right end of the first elastic strip 8 to swing, which will not affect the passage of the slider 5.

[0058] Reference Figures 2 to 5 As shown in the figure, a linkage mechanism for driving the wiping device 4 to move is provided between the sliding cover 12 and the wiping device 4, and the linkage mechanism includes a sliding post 13, a square groove 14, a square rod 15 and a spring 17. A through groove for the sliding post 13 to pass through is provided on the fixed frame 16, and the sliding post 13 is fixedly connected to the inner wall of the sliding cover 12. The square groove 14 is provided on one end of the sliding post 13 close to the wiping device 4, and the square rod 15 is slidably arranged inside the square groove 14. The square rod 15 and the sliding post 13 are distributed in a T shape, and the square rod 15 is fixedly connected to the outer wall of the liquid box 401. Two springs 17 are provided, and the two springs 17 are respectively mounted on both ends of the square rod 15. One end of the spring 17 is fixedly connected to the sliding post 13, and the other end of the spring 17 is fixedly connected to the outer wall of the liquid box 401.

[0059] Structures such as the sliding column 13, the square groove 14, and the square rod 15 are provided so that the sliding cover 12 can also move along the width direction of the slide groove 6 when driving the wiping device 4 to move along the length direction of the slide groove 6, thereby facilitating switching between the first sliding area 10 or the second sliding area 11. For example, when entering the first sliding area 10, the square rod 15 adaptively slides inside the square groove 14, and the spring 17 on the side corresponding to the first sliding area 10 extends, while the other spring 17 contracts.

[0060] In addition, structures such as balls may be provided on the inner wall of the square groove 14 and the square rod 15 to increase the smoothness of the sliding of the square rod 15 in the square groove 14, which can be adjusted according to specific usage conditions.

[0061] Reference Figure 5 As shown in FIG, an elastic telescopic rod 23 is fixedly connected to the corner of the slide groove 6, and the elastic telescopic rod 23 is close to the first elastic strip 8 and is located on the side of the slide groove 6 away from the door lock device 3.

[0062] The sliding cover 12 drives the wiping device 4 to move along the trajectory of the second sliding area 11. When the slider 5 moves to the moment of being offset from the second elastic strip 9, the wiping device 4 swings under the action of the restoring force of the spring 17, causing the cleaning liquid inside the liquid box 401 to shake and enter the absorbent cotton 402, which is convenient for subsequent wiping and cleaning; and at the first elastic strip 8, when the slider 5 moves to the moment of being offset from the first elastic strip 8, the elastic telescopic rod 23 can contact the slider 5, thereby alleviating the swing of the wiping device 4 and preventing the cleaning liquid inside the liquid box 401 from shaking significantly.

[0063] Reference Figure 4 As shown in , considering that cleaning liquid residue is likely to appear at the wiping position, in order to achieve the effect of rapid air drying and prevent the appearance of watermarks, an airbag 18 is provided between the fixed frame 16 and the sliding cover 12. One end of the airbag 18 is fixedly connected to the outer wall of the fixed frame 16, and the other end of the airbag 18 is fixedly connected to the inner wall of the sliding cover 12. The airbag 18 has a certain elastic deformation force.

[0064] An exhaust mechanism cooperating with the airbag 18 is provided inside the fixed frame 16. The exhaust mechanism includes an exhaust pipe 19 and a first one-way valve 20. The exhaust pipe 19 is slidably provided on the side wall of the fixed frame 16. The exhaust pipe 19 is connected to the airbag 18. The first one-way valve 20 is installed on the exhaust pipe 19. The first one-way valve 20 allows the gas inside the airbag 18 to be ejected from the exhaust pipe 19 without reverse flow. The exhaust pipe 19 is L-shaped.

[0065] The sliding cover 12 is provided with an air intake mechanism that cooperates with the airbag 18. The air intake mechanism includes an air intake pipe 21 and a second one-way valve 22. The air intake pipe 21 is fixedly connected to the sliding cover 12 and communicates with the airbag 18. The end of the air intake pipe 21 away from the airbag 18 is connected to the external atmosphere. The second one-way valve 22 is mounted on the air intake pipe 21. The second one-way valve 22 allows external air to enter the interior of the airbag 18 through the air intake pipe 21 without reverse flow. In addition, a filter device can be provided on the air intake pipe 21. The filter device includes a filter screen and other structures to filter out dust and other impurities in the external air.

[0066] When the operator opens the sliding cover 12, the sliding cover 12 pulls the airbag 18, allowing external air to enter the interior of the airbag 18 through the air inlet pipe 21, and the airbag 18 expands and becomes larger, thereby realizing the air intake operation; when the sliding cover 12 is closed, the sliding cover 12 squeezes the airbag 18, and the gas inside the airbag 18 is ejected from the air outlet pipe 19, quickly drying the wiped area, thereby improving the use efficiency of the key cabinet.

[0067] The size of the air bag 18 is set appropriately to ensure that there is enough gas inside to achieve the air-drying effect.

[0068] In addition, air holes and other structures can be provided at the bottom end of the sliding cover 12 to cooperate with the air outlet pipe 19 to achieve gas flow, which can be adjusted according to specific usage conditions.

[0069] The present invention provides structures such as an air bag 18 and utilizes the power of the sliding cover 12 to achieve expansion and contraction, thereby quickly drying the wiping position.

[0070] The end of the air outlet pipe 19 away from the air bag 18 is connected to a hose 24, and the hose 24 is vertically downward and toward the door lock device 3. When the gas is ejected from the air outlet pipe 19 and the hose 24, the hose 24 will swing under the force of the air flow, expanding the range of the wind force and improving the drying effect.

[0071] refer to Figures 6 to 9As shown in the figure, in the present invention, a key panel 29 is further provided inside the cabinet 1, and a plurality of lock slots 26 are provided on the key panel 29, and a key 27 is inserted and fixed on the lock slot 26, and a key ring 28 is connected to the keyhole of the key 27. The key ring 28 plays a limiting role to prevent the key 27 from being excessively inserted into the lock slot 26. Furthermore, a portrait recognition camera 25 is provided above each lock slot 26. The portrait recognition camera 25 can identify authorized personnel through image recognition technology. Different authorized personnel may match different keys 27. Therefore, when the corresponding authorized personnel is identified by the portrait recognition camera 25, the locking mechanism 31 for locking the key 27 on the key panel 29 will be opened, so that the authorized personnel can smoothly take and put the key; it has the effect of double protection, strong safety and pertinence, and replaces the method of taking and putting all keys 27 after opening the cabinet 1 in the prior art.

[0072] refer to Figure 9 and Figure 10 As shown in , the locking mechanism 31 of the present invention includes a limit block 34, a power positioning block 35, a guide rod 36 and a guide spring 38. The power positioning block 35 is fixed to a side of the key panel 29 located inside the cabinet 1, and the guide rod 36 movably passes through both sides of the power positioning block 35. The end of the guide rod 36 is fixedly connected to the end of the limit block 34. The end of the limit block 34 close to the guide rod 36 is fixedly provided with a guide spring 38. The end of the guide spring 38 away from the limit block 34 is fixed to the power positioning block 35. The guide spring 38 is movably sleeved on the guide rod 36. The limit block 34 is provided with an inclined surface on the side facing the key panel 29, and the limit block 34 is correspondingly inserted into the keyhole on the key 27, thereby limiting the key 27 to the key panel 29.

[0073] During operation, when the key 27 is inserted into the lock slot 26, the end of the key 27 hits the inclined surface on the limit block 34, causing the limit block 34 to move toward the power positioning block 35 to avoid it. At this time, the key 27 can be smoothly inserted into the lock slot 26. When the keyhole on the key 27 corresponds to the limit block 34, the key 27 loses its resistance to the limit block 34. At this time, the elastic reset effect of the guide spring 38 can drive the limit block 34 to be inserted into the keyhole on the key 27, thereby locking the key 27.

[0074] Furthermore, in the present invention, the power positioning block 35 is an electromagnet, which can generate magnetism when energized. The magnetism can attract the limit block 34, so that the limit block 34 is moved out of the keyhole on the key 27. Therefore, when the portrait recognition camera 25 recognizes the authorized person, the power positioning block 35 can be turned on by the control chip to complete the automatic unlocking of the key 27. The operation is simple and the principle is simple.

[0075] When the key 27 is used, water stains are usually easily adhered to the key 27. If it is not wiped clean or oiled during the process of taking it out, the key 27 is prone to rust, which in turn affects the use of the lock structure and reduces the service life of the key 27 and the lock structure.

[0076] Therefore, in the present invention, a maintenance mechanism 30 is further provided between the key panel 29 and the interior of the cabinet 1 . The maintenance mechanism 30 is used to automatically oil the key 27 to prevent the key 27 from rusting.

[0077] Specifically, the maintenance mechanism 30 includes an oil storage box 37, a sponge block 32 and a socket 33. The oil storage box 37 is fixedly arranged on the inner wall of the cabinet 1, one end of the sponge block 32 is connected to the inside of the oil storage box 37, and the other end of the sponge block 32 extends out of the oil storage box 37 and is arranged toward the key panel 29. The socket 33 is arranged at the end of the sponge block 32 extending out of the oil storage box 37. Oil is stored in the oil storage box 37, and the oil can be soaked into the sponge block 32. When the key 27 is inserted into the lock slot 26, the end of the key 27 just extends into the socket 33. On the one hand, it is isolated from the air, and on the other hand, the oil soaked on the sponge block 32 is used for maintenance, thereby extending the service life of the key 27. The setting of the sponge block 32 can clean the key 27, which is highly practical.

[0078] It should be noted that the entire metal portion of the key 27 extends into the insertion hole 33 .
