Detailed implementation mode

[0027] The present invention provides a key cabinet with a dual protection function as shown in Figure 1 which includes a cabinet body 1 and a cabinet door 2 hinged to the cabinet body 1. Keys are placed in the cabinet body 1 to achieve centralized management. The cabinet door 2 can be set as a transparent acrylic board and selected according to actual needs, which will not be elaborated here.

[0028] Referring to Figure 1 and Figure 4 as shown, a door lock device 3 is arranged on the cabinet door 2. 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 of password recognition, mechanical key and fingerprint recognition. In order to improve the safety level, an unlocking method is set that requires at least two or three recognitions to be successful before the cabinet door 2 can be opened.

[0029] Among them, password recognition, mechanical key and fingerprint recognition are all common existing technologies and will not be elaborated here.

[0030] In the present invention, a fixed frame 16 is fixedly connected to the cabinet door 2. The fixed frame 16 surrounds the outside of the door lock device 3, and a sliding cover 12 is slidably arranged outside the fixed frame 16.

[0031] When it is necessary to open the key cabinet by using the door lock device 3, the operator slides the sliding cover 12 to open the fixed frame 16, which is convenient for using the password input area 301, the keyhole 302, the fingerprint recognition area 303, etc. After use, the sliding cover 12 is controlled to reset to close the fixed frame 16, so as to protect the door lock device 3 and prevent the password input area 301, the keyhole 302, the fingerprint recognition area 303, etc. from being affected by dust and extend the service life.

[0032] Referring toFigure 3 and Figure 4 As shown, considering that due to the presence of sweat on a person's fingerprint, especially in situations such as summer, it is easy to leave marks on the password input area 301 and the fingerprint recognition area 303. Especially after repeated use, these marks may accumulate and form obvious fingerprint imprints, which may be speculated by outsiders to obtain the password and be exploited. Especially when there are many keys placed in the cabinet body 1, to ensure the security 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 a water-absorbing cotton 402. Among them, the water-absorbing cotton 402 is close to the door lock device 3. Cleaning liquid, such as anhydrous alcohol, can be injected into the interior of the liquid box 401. And a through hole (not shown in the figure) is provided on one side of the liquid box 401 close to the water-absorbing cotton 402, so that the cleaning liquid can penetrate into the water-absorbing cotton 402, facilitating the wiping of the door lock device 3. And the sliding cover 12 can drive the wiping device 4 to move synchronously. By setting the wiping device 4, it can wipe and clean the door lock device 3 after use, prevent the leaving of fingerprint marks, and at the same time ensure the hygiene of the use of the door lock device 3.

[0033] In addition, a liquid injection pipe and other structures are provided on the liquid box 401, facilitating the injection of cleaning liquid into the interior of the liquid box 401.

[0034] Reference Figures 3 to 5 As shown, 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 being in a wet state are likely to cause unlocking failure, and it will also increase the wear of the water-absorbing cotton 402, resulting in waste of the cleaning liquid. To improve the use efficiency, sliding grooves 6 are provided on the inner walls at the upper and lower ends of the fixed frame 16. A first sliding area 10 and a second sliding area 11 are formed inside the sliding grooves 6 by a guiding mechanism. Among them, the first sliding area 10 is close to the door lock device 3, and the second sliding area 11 is far from the door lock device 3.

[0035] 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, and the wiping device 4 does not contact the door lock device 3, so it will not perform wiping treatment on the door lock device 3, preventing the password input area 301 and the fingerprint recognition area 303 from being in a wet state before unlocking, which may lead to unlocking failure, reducing the wear of the water-absorbing cotton 402, and avoiding waste of the cleaning liquid.

[0036] After unlocking, when closing the sliding cover 12, the sliding cover 12 drives the wiping device 4 to move along the trajectory of the first sliding area 10, and the wiping device 4 contacts the door lock device 3. The wiping device 4 can wipe the used password input area 301 and the fingerprint recognition area 303.

[0037] The present invention guides the position of the wiping device 4 during its movement by providing structures such as the first sliding area 10 and the second sliding area 11, preventing the password input area 301 and the fingerprint recognition area 303 from being in a wet state before unlocking, which may lead to unlocking failure, reducing the wear of the water-absorbing cotton 402, and avoiding the waste of the cleaning liquid.

[0038] As shown in Figure 6 When specifically arranged, the guiding mechanism includes a partition plate 7, a first elastic strip 8 and a second elastic strip 9. The partition plate 7 is distributed along the length direction of the sliding groove 6. The partition plate 7 is located between the first elastic strip 8 and the second elastic strip 9. The partition plate 7 is fixedly connected to the inner wall of the sliding groove 6. One end of the first elastic strip 8 away from the partition plate 7 is inclined towards the door lock device 3, and one end of the second elastic strip 9 away from the partition plate 7 is inclined away from the door lock device 3.

[0039] A sliding mechanism cooperating with the guiding mechanism is arranged inside the sliding groove 6. The sliding mechanism includes a slider 5. The slider 5 is fixedly connected to the wiping device 4, and the width value of the slider 5 is smaller than the width values 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 balls can be arranged outside the slider 5 to reduce the moving friction of the slider 5.

[0040] As shown in Figure 6 When the slider 5 slides from right to left inside the sliding groove 6, under the guiding action of the first elastic strip 8, the slider 5 will enter the second sliding area 11 and then slide 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 without affecting the passing of the slider 5. When the slider 5 slides from left to right inside the sliding groove 6, under the guiding action of the second elastic strip 9, the slider 5 will enter the first sliding area 10 and then slide 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 without affecting the passing of the slider 5.

[0041] As shown in Figures 2 to 5 A linkage mechanism for driving the wiping device 4 to move is arranged between the sliding cover 12 and the wiping device 4. The linkage mechanism includes a sliding column 13, a square groove 14, a square rod 15 and a spring 17. A through groove for the sliding column 13 to pass through is opened on the fixed frame 16. The sliding column 13 is fixedly connected to the inner wall of the sliding cover 12. The square groove 14 is opened at one end of the sliding column 13 close to the wiping device 4. The square rod 15 is slidably arranged inside the square groove 14. The square rod 15 and the sliding column 13 are distributed in a T shape. The square rod 15 is fixedly connected to the outer wall of the liquid box 401. There are two springs 17. The two springs 17 are respectively sleeved at both ends of the square rod 15. One end of the spring 17 is fixedly connected to the sliding column 13, and the other end of the spring 17 is fixedly connected to the outer wall of the liquid box 401.

[0042] Structures such as the slide column 13, the square groove 14, and the square rod 15 are provided so that the slide 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 is extended, while the other spring 17 is contracted.

[0043] 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.

[0044] Reference Figure 5 As shown in FIG, an elastic telescopic rod 23 is fixedly connected to the corner of the slide slot 6, and the elastic telescopic rod 23 is close to the first elastic strip 8 and is located on the side of the slide slot 6 away from the door lock device 3.

[0045] The sliding cover 12 drives the wiping device 4 to move along the trajectory of the second sliding area 11. When the sliding block 5 moves to the moment where it is offset from the second elastic strip 9, the wiping device 4 swings under the action of the restoring elastic 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 sliding block 5 moves to the moment where it is offset from the first elastic strip 8, the elastic telescopic rod 23 can contact the sliding block 5, thereby alleviating the swing of the wiping device 4 and preventing the cleaning liquid inside the liquid box 401 from shaking significantly.

[0046] Reference Figure 4 As shown in , considering that cleaning liquid residue is likely to remain 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.

[0047] An exhaust mechanism cooperating with the airbag 18 is provided inside the fixed frame 16, and 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, and the exhaust pipe 19 is connected with 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.

[0048] An air intake mechanism cooperating with the airbag 18 is provided on the sliding cover 12. The air intake mechanism includes an air inlet pipe 21 and a second one-way valve 22. The air inlet pipe 21 is fixedly connected to the sliding cover 12. The air inlet pipe 21 communicates with the airbag 18. One end of the air inlet pipe 21 away from the airbag 18 communicates with the external atmospheric environment. The second one-way valve 22 is installed on the air inlet pipe 21. The second one-way valve 22 enables external air to enter the interior of the airbag 18 through the air inlet pipe 21 without reverse flow. In addition, a filtering device can be provided on the air inlet pipe 21. The filtering device includes structures such as a filter net to filter dust and other impurities in the external air.

[0049] When the operator opens the sliding cover 12, the sliding cover 12 pulls the airbag 18, causing external air to enter the interior of the airbag 18 through the air inlet pipe 21. The airbag 18 expands and becomes larger, 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 to quickly air-dry the wiping position, improving the use efficiency of the key cabinet.

[0050] The size of the airbag 18 is set appropriately to ensure that there is enough gas inside it to achieve the air-drying effect.

[0051] In addition, structures such as air holes can be provided at the bottom end of the sliding cover 12 to cooperate with the air outlet pipe 19 to realize gas flow, which can be adjusted according to specific usage situations.

[0052] The present invention realizes expansion and contraction by setting structures such as the airbag 18 and using the power of the movement of the sliding cover 12 to quickly air-dry the wiping position.

[0053] One end of the air outlet pipe 19 away from the airbag 18 is communicated with a hose 24, and the hose 24 is vertically downward and faces 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 action of the air flow force, expanding the range of the wind force and improving the air-drying effect.

[0054] Reference Figures 6 to 9As shown in the figure, in the present invention, a key panel 29 is further provided inside the cabinet body 1. A plurality of lock slots 26 are provided on the key panel 29. A key 27 is inserted and fixed in the lock slot 26. A key ring 28 is connected to the keyhole of the key 27. The key ring 28 plays a limiting role and can prevent the key 27 from being inserted into the lock slot 26 excessively. Further, 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 be matched with different keys 27. Therefore, when the corresponding authorized personnel are recognized by the portrait recognition camera 25, the locking mechanism 31 for locking the key 27 on the key panel 29 will be opened, enabling the authorized personnel to smoothly pick up and place the key; it has achieved the effect of double protection, with strong safety and pertinence, and replaces the way in the prior art that all keys 27 can be picked up and placed after opening the cabinet body 1.

[0055] Reference Figure 9 and Figure 10 As shown in the figure, in the present invention, the locking mechanism 31 includes a limiting block 34, a power positioning block 35, a guiding round rod 36 and a guiding spring 38. The power positioning block 35 is fixed on the side of the key panel 29 inside the cabinet body 1. The guiding round rod 36 movably passes through both sides of the power positioning block 35. The end of the guiding round rod 36 is fixedly connected to the end of the limiting block 34. A guiding spring 38 is fixedly arranged at one end of the limiting block 34 close to the guiding round rod 36. The end of the guiding spring 38 away from the limiting block 34 is fixed on the power positioning block 35. The guiding spring 38 is movably sleeved on the guiding round rod 36. An inclined surface is provided on the side of the limiting block 34 facing the key panel 29, and the limiting block 34 is correspondingly inserted into the keyhole on the key 27, achieving the purpose of limiting the key 27 on the key panel 29; During operation, when the key 27 is inserted into the lock slot 26, the end of the key 27 abuts against the inclined surface on the limiting block 34, causing the limiting block 34 to move towards the power positioning block 35 for avoidance. 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 limiting block 34, the key 27 loses the abutting force on the limiting block 34. At this time, the elastic reset function of the guiding spring 38 can drive the limiting block 34 to be inserted into the keyhole on the key 27 to lock the key 27.

[0056] Further, in the present invention, the power positioning block 35 is an electromagnet. When the power positioning block 35 is energized, it can generate magnetism, and the magnetism can attract the limiting block 34, causing the limiting block 34 to move out of the keyhole on the key 27. Therefore, when the portrait recognition camera 25 recognizes authorized personnel, the power positioning block 35 can be turned on through the control chip to complete the automatic unlocking of the key 27, with simple operation and principle.

[0057] During the use of the key 27, water stains are usually likely to adhere to the key 27. If it is not wiped clean or not oiled during the process of taking and placing, the key 27 is likely to rust, which will affect the use of the lock structure and reduce the service life of the key 27 and the lock structure.

[0058] Therefore, in the present invention, a maintenance mechanism 30 is further provided between the key panel 29 and the interior of the cabinet body 1. The maintenance mechanism 30 is used for automatically oiling and maintaining the key 27 to prevent the key 27 from rusting.

[0059] Specifically, the maintenance mechanism 30 includes an oil storage box 37, a sponge block 32 and a jack 33. The oil storage box 37 is fixedly arranged on the inner wall of the cabinet body 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 towards the key panel 29. The jack 33 is arranged at the end of the sponge block 32 that extends out of the oil storage box 37. The oil storage box 37 stores oil liquid, and the oil liquid can infiltrate into the sponge block 32. When the key 27 is inserted into the lock groove 26, the end of the key 27 just extends into the jack 33. On the one hand, it is isolated from the air, and on the other hand, it is maintained by the oil liquid infiltrated on the sponge block 32, which prolongs the service life of the key 27. Moreover, the setting of the sponge block 32 can play the role of cleaning the key 27, and it has strong practicability.

[0060] It should be noted that all the metal parts on the key 27 extend into the jack 33.
