Description

Technical Field

[0001] This invention relates to the field of key cabinets, specifically to an intelligent key cabinet. Background Technology

[0002] Prisons are places for detaining criminals, and the supervision of criminals within prisons is very important. Therefore, prisons have a large number of prison doors, and each prison door is matched with a different key. As a result, a large number of keys need to be centrally managed, and key strings are usually locked in key cabinets for centralized processing.

[0003] Because there are many keys that need to be stored and managed, and they need to be placed separately, the existing key cabinets are mostly large in size. This makes it inconvenient for prison staff to move and hide them. When an emergency occurs in the prison, the staff need to flip the key cabinets one by one to find the keys. Also, because of their large size, staff need to climb up to retrieve keys that are on higher shelves. This process is too time-consuming and prolongs the time it takes for staff to handle the situation, thus reducing the efficiency of emergency response.

[0004] In conclusion, the aforementioned key cabinets are inconvenient for moving and concealing keys during use. Furthermore, keys located at higher positions require prison staff to climb up to retrieve them, which is time-consuming and prolongs the time available for staff to handle situations, thus reducing the efficiency of emergency response. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an intelligent key cabinet to solve the technical problems of inconvenience in moving and hiding keys during use, and the need for prison staff to climb up to retrieve keys that are located at a high position, which is too time-consuming and prolongs the time available for staff to handle situations, thus reducing the efficiency of handling emergencies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent key cabinet, comprising a cabinet body, a cover plate slidably disposed on the top of the cabinet body, a second rack disposed on the inner side of the cover plate, and a fixed gear meshing with the second rack disposed within the interlayer of the cabinet body, a second transmission mechanism disposed on one side of the fixed gear, and a bidirectional threaded rod connected to the other end of the second transmission mechanism, one end of the bidirectional threaded rod penetrating into the interior of the cabinet body, and support rods symmetrically slidably disposed on the outer wall of the bidirectional threaded rod, the other end of each support rod being hinged to a top plate, a rotating placement plate and a fixed placement plate respectively disposed on the top of the top plate, a first rack obliquely symmetrically disposed inside the cabinet body, a worm gear rotatably disposed on the bottom of the top plate, and a non-circular gear meshing with the first rack connected to one end of the worm gear, and a worm wheel cooperating with the worm gear disposed on the bottom of the top plate, the top of the worm wheel penetrating the top plate through a rotating shaft, and the top of the rotating shaft being connected to the rotating placement plate.

[0007] By adopting the above technical solution, pulling the cover plate upward causes the second rack to drive the fixed gear to rotate, which in turn drives the bidirectional threaded rod to rotate through the second transmission mechanism. With the cooperation of the threaded sleeve and the support rod, the top plate inside the cabinet is lifted, thereby lifting the placement plate from inside the cabinet. This makes it easier for prison staff to directly access the keys. Furthermore, during the upward movement of the top plate, the irregular gear at the bottom rotates under the action of the first rack. Under the action of the worm gear, the two sets of rotating placement plates on the top plate rotate at a certain angle, further presenting all the placement plates to the prison management personnel, thus improving the efficiency of prison management personnel in handling emergencies.

[0008] The present invention is further configured such that the outer wall of the bidirectional threaded rod is symmetrically provided with threaded sleeves, and the top of the threaded sleeves is hinged to the support rod.

[0009] By adopting the above technical solution, the bidirectional threaded rod rotates under the action of the second transmission mechanism, which in turn drives the threaded sleeve on the outer wall to rotate. Since the top of the threaded sleeve and the support rod are hinged, the threaded sleeve will cooperate with the support rod to make the top plate slide up and down during the sliding process.

[0010] The invention is further configured such that the outer wall of the bidirectional threaded rod is provided with an elastic airbag on one side of the threaded sleeve, the top of the elastic airbag is connected to an air pipe through a corrugated pipe, the other end of the air pipe passes through the top plate and is connected to a spray disc, and the spray disc is located at the middle position between the rotating placement plate and the fixed placement plate.

[0011] By adopting the above technical solution, during the process of the top plate rising, the elastic airbag returns to its original shape and draws in outside air. After the prison management personnel have taken the keys, the cover plate is inserted into the cabinet. At this time, the fixed gear will rotate in the opposite direction. Under the action of the second transmission mechanism, the threaded sleeve squeezes the elastic airbag, thereby causing the air in the elastic airbag to be discharged into the spray plate through the air pipe. Under the action of the spray plate, the keys on the placement plate are blown away to remove dust, effectively preventing external impurities and dust from contaminating the keys inside and extending the service life of the keys.

[0012] The invention is further configured such that side panels are slidably provided on both sides of the top of the cabinet on the cover plate, observation windows are installed on the side panels, and a cleaning plate is provided in the interlayer of the cabinet.

[0013] By adopting the above technical solution, the observation window on the side panel allows staff to observe the storage of keys inside in real time. At the same time, as the side panel slides down, the cleaning plate in the cabinet compartment facilitates cleaning of the inner wall of the observation window, ensuring the clarity of subsequent observations.

[0014] The present invention is further configured such that a spur bevel gear is provided on the other side of the fixed gear on the second transmission mechanism, and a side bevel gear meshes with it at its bottom. The bottom of the side bevel gear is connected to a first transmission mechanism, and the other end of the first transmission mechanism is connected to a one-way threaded rod, and the one-way threaded rod is threadedly connected to the side plate.

[0015] By adopting the above technical solution, the fixed gear will drive the spur bevel gear on one side to rotate. The meshing of the spur bevel gear and the side bevel gear will drive the first transmission mechanism at the bottom to rotate. Since the one-way threaded rod and the side plate are connected by a thread, the side plate can slide up and down in the cabinet's interlayer during the rotation of the one-way threaded rod driven by the first transmission mechanism.

[0016] The present invention is further configured such that an array of display screens is installed at the front end of the cabinet corresponding to the rotating placement plate and the fixed placement plate, and the key hooks on the rotating placement plate and the fixed placement plate are electrically connected to the display screens.

[0017] By adopting the above technical solution, the number of keys in the cabinet can be intuitively viewed on the display screen, which makes it easy for prison management personnel to check the number of keys when they leave work, without the need for manual inspection, thus reducing the workload of prison management personnel.

[0018] The present invention is further configured such that both the first transmission mechanism and the second transmission mechanism include a driving disc, a transmission belt and a driven disc, the driving disc of the first transmission mechanism is connected to a side bevel gear and one end of its driven disc is connected to a one-way threaded rod, and the driving disc of the second transmission mechanism is connected to a fixed gear and one end of its driven disc is connected to a two-way threaded rod.

[0019] By adopting the above technical solution, the side bevel gear will drive the drive disc on the first transmission mechanism to rotate, and in cooperation with the transmission belt, it will drive the one-way threaded rod at one end to rotate. At the same time, the fixed gear will drive the drive disc on the second transmission mechanism to rotate, and in cooperation with the transmission belt, it will drive the two-way threaded rod at one end to rotate.

[0020] The present invention is further configured such that a brush is provided on one side of the cleaning plate, and the cleaning plate is detachably connected to the cabinet.

[0021] By adopting the above technical solution, the brush itself is made of carbon fiber material, which has the property of being soft. During the operation, it can sweep away the dust on the inner wall of the observation window, further improving the clarity of the observation window. At the same time, the detachable setting between the cleaning plate and the cabinet makes it convenient for prison management personnel to maintain and replace the cleaning plate regularly.

[0022] The present invention is further configured such that a damping structure is provided between the cabinet body and the cover plate.

[0023] By adopting the above technical solution, the sliding friction between the cabinet and the cover plate is improved, effectively preventing the cabinet from sliding under slight external impact.

[0024] In summary, the present invention has the following main beneficial effects:

[0025] 1. This invention features a second rack on the inner side of the cover plate. Pulling the cover plate upward causes the second rack to rotate the fixed gear, which in turn drives the bidirectional threaded rod to rotate via a second transmission mechanism. With the cooperation of the threaded sleeve and the support rod, the top plate inside the cabinet is lifted, thus raising the placement plate from inside the cabinet. This allows prison staff to directly access the keys. In practical use, the overall size of the device is greatly reduced, making it easier for prison management personnel to move and conceal it. Furthermore, during the lifting of the top plate, the irregular gear at the bottom rotates under the action of the first rack. Under the action of the worm gear, the two sets of rotating placement plates on the top plate rotate at a certain angle, further presenting all the placement plates to the prison management personnel, thus improving the efficiency of prison management personnel in handling emergencies.

[0026] 2. This invention features elastic airbags on both sides of a bidirectional threaded rod. As the top plate rises, the elastic airbags return to their original shape, drawing in outside air. After prison staff retrieve the keys, the cover plate is inserted into the cabinet. At this point, the fixed gear rotates in the opposite direction, and under the action of the second transmission mechanism, the threaded sleeve compresses the elastic airbags, causing the air inside the airbags to be discharged through the air pipe into the spray disc. The spray disc blows dust off the keys on the placement plate, effectively preventing external impurities and dust from contaminating the keys and extending their service life.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of the present invention will now be described.

[0040] A smart key cabinet, such as Figures 1-10As shown, the system includes a cabinet 1, a cover plate 2, side plates 3, a transmission mechanism, a support mechanism, and a cleaning mechanism. The cover plate 2 and side plates 3 are slidably mounted on the top of the cabinet 1. A handle 5 is provided on the top of the cover plate 2. Prison management personnel pull the cover plate 2 upwards using the handle 5, causing it to slide upwards. A second rack 27 is located on the inner side of the cover plate 2, and a fixed gear 18 meshing with the second rack 27 is located within the interlayer of the cabinet 1. Therefore, the upward sliding of the cover plate 2 will drive the fixed gear 18 to rotate. A second transmission mechanism 23 is located on one side of the fixed gear 18, and a bidirectional threaded rod 14 is connected to the other end of the second transmission mechanism 23. One end of the bidirectional threaded rod 14 penetrates into the interior of the cabinet 1. The outer wall of the bidirectional threaded rod 14 is symmetrically provided with threaded sleeves 24, and the top of the threaded sleeves 24 is hinged to the support rod 13. A top plate 15 is hinged to the other end of each support rod 13. Under the action of the second transmission mechanism 23, the bidirectional threaded rod 14 rotates, thus driving the threaded sleeves 24 on the outer wall to rotate. Simultaneously, a limiting mechanism is provided at the bottom of the threaded sleeves 24. During the rotation of the threaded sleeves 24 driven by the bidirectional threaded rod 14, the limiting mechanism prevents the threaded sleeves 24 from rotating along with it, thus ensuring stable sliding of the threaded sleeves 24 on the outer wall of the bidirectional threaded rod 14. Since the top of the threaded sleeves 24 is hinged to the support rod 13, during the sliding process of the threaded sleeves 24, they cooperate with the support rod 13 to make the top plate... 15 slides upwards. A fixed placement plate 9 and a rotating placement plate 7 are located at the top of the top plate 15. The fixed placement plate 9 is located in the middle of the top of the top plate 15, while the rotating placement plates 7 are located on either side of the fixed placement plate 9. During the rising of the top plate 15, the fixed placement plate 9 and the rotating placement plate 7 are lifted from inside the cabinet 1, allowing prison staff to directly access the keys. When the top plate 15 rises to the same height as the cabinet 1, the staff continues to pull the cover plate 2 to remove it from the cabinet 1. During this process, the bidirectional threaded rod 14 continues to rotate, and the top plate 15 continues to rise. Because the first rack 8 is obliquely symmetrically arranged inside the cabinet 1, and a worm gear 17 is rotatably arranged at the bottom of the top plate 15, with one end of the worm gear 17 connected to the first rack 8... The top plate 15 has a meshing shaped gear 11 and a worm wheel 26 that meshes with the worm 17 at its bottom. The top of the worm wheel 26 passes through the top plate 15 and is connected to a rotating shaft 16. The worm wheel 26 is located on the outer wall of the rotating shaft 16 and is connected to the rotating placement plate 7. Therefore, as the top plate 15 continues to rise, the shaped gear 11 at the bottom will rotate under the action of the first rack 8. Under the action of the worm wheel 26 and the worm 17, the two sets of rotating placement plates 7 on the top plate 15 will rotate at a certain angle, further presenting all the placement plates to the prison management personnel, allowing them to directly access the keys and improving the efficiency of handling emergencies. The outer wall of the bidirectional threaded rod 14 is provided with elastic airbags 25 on one side of the threaded sleeve 24.The top of each elastic airbag 25 is connected to an air pipe 10 via a corrugated pipe 12. The other end of the air pipe 10 passes through the top plate 15 and is connected to a spray disc 6. The spray disc 6 is located in the middle of the side between the rotating placement plate 7 and the fixed placement plate 9. During the process of the top plate 15 rising, the elastic airbag 25 returns to its original shape and draws in outside air. After the prison management personnel have taken the key, the cover plate 2 is then inserted into the cabinet 1. At this time, the fixed gear 18 will rotate in the opposite direction. Under the action of the second transmission mechanism 23, the threaded sleeve 24 compresses the elastic airbag 25, thereby causing the air inside the elastic airbag 25 to be drawn out. Air is expelled through the air pipe 10 into the spray disc 6, which blows dust off the keys on the placement plate, effectively preventing external impurities and dust from contaminating the keys and extending their lifespan. Simultaneously, as the cover plate 2 slides downwards, it drives the fixed gear 18 to rotate in the opposite direction. At this time, the top plate 15 drives the rotating placement plate 7 and the fixed placement plate 9 to retract into the cabinet. At the same time, the side plate 3 rises up and cooperates with the cover plate 2 to seal the cabinet 1. This significantly reduces the overall size of the device in actual use, making it easier for prison management personnel to move and conceal it.

[0041] Please see Figure 1 and Figure 6 A spur bevel gear 19 is provided on the other side of the fixed gear 18, which is located in the second transmission mechanism 23. A side bevel gear 20 is meshed at its bottom. The bottom of the side bevel gear 20 is connected to the first transmission mechanism 21. The other end of the first transmission mechanism 21 is connected to a one-way threaded rod 22. The one-way threaded rod 22 is threadedly connected to the side plate 3. Under the action of the fixed gear 18, the spur bevel gear 19 on one side will rotate. The meshing of the spur bevel gear 19 and the side bevel gear 20 will drive the first transmission mechanism 21 at the bottom to rotate. Since the one-way threaded rod 22 is threadedly connected to the side plate 3, the side plate 3 can slide up and down in the interlayer of the cabinet 1 during the rotation of the one-way threaded rod 22 driven by the first transmission mechanism 21.

[0042] Please see Figure 1 , Figure 2 and Figure 3The top of the cabinet 1 has side panels 3 that slide on both sides of the cover plate 2. Observation windows 28 are installed on the side panels 3, and a cleaning plate 29 is installed in the interlayer of the cabinet 1. The observation windows 28 on the side panels 3 allow staff to observe the storage of keys inside in real time. At the same time, as the side panels 3 slide down, the cleaning plate 29 in the interlayer of the cabinet 1 can be used to clean the inner wall of the observation windows 28 to ensure the clarity of subsequent observation. A brush is installed on one side of the cleaning plate 29, and the cleaning plate 29 is detachable from the cabinet 1. The brush itself is made of carbon fiber material, which has soft properties. During operation, it can sweep away dust from the inner wall of the observation windows 28, further improving the clarity of the observation windows 28. The detachable design of the cleaning plate 29 from the cabinet 1 also facilitates regular maintenance and replacement of the cleaning plate 29 by prison management personnel.

[0043] Please see Figure 1 and Figure 2 An array display screen 4 is installed at the front end of the cabinet 1, corresponding to the rotating placement plate 7 and the fixed placement plate 9. The key hooks on the rotating placement plate 7 and the fixed placement plate 9 are electrically connected to the display screen 4. The display screen 4 allows prison management personnel to intuitively view the number of keys in the cabinet 1, which is convenient for prison management personnel to check the number of keys when leaving get off work without manual inspection, thus reducing the workload of prison management personnel. A sensor is installed on the key hook to detect whether there is a key on the hook, which will then be displayed on the display screen 4. The specific working principle of the electrical connection between the display screen 4 and the key hook is prior art to those skilled in the art, so its specific working principle is not described in detail in this application.

[0044] Please see Figure 4 and Figure 6 Both the first transmission mechanism 21 and the second transmission mechanism 23 include a driving disc, a transmission belt, and a driven disc. The driving disc on the first transmission mechanism 21 is connected to the side bevel gear 20, and one end of its driven disc is connected to the one-way threaded rod 22. The driving disc on the second transmission mechanism 23 is connected to the fixed gear 18, and one end of its driven disc is connected to the two-way threaded rod 14. Under the action of the side bevel gear 20, the driving disc on the first transmission mechanism 21 will rotate, and in cooperation with the transmission belt, it will drive the one-way threaded rod 22 at one end to rotate. At the same time, the fixed gear 18 will drive the driving disc on the second transmission mechanism to rotate, and in cooperation with the transmission belt, it will drive the two-way threaded rod 14 at one end to rotate.

[0045] The working principle of this invention is as follows: When in use, prison management personnel pull up the cover plate 2 through the handle 5. Under the action of the second rack 27, the fixed gear 18 will rotate. Under the action of the second transmission mechanism 23, the bidirectional threaded rod 14 will rotate. Under the action of the threaded sleeve 24 and the support rod 13, the top plate 15 will rise, allowing the placement plate to rise from inside the cabinet 1, making it convenient for prison staff to directly retrieve the keys. At the same time, during the rising of the top plate 15, the irregular gear 11 at the bottom will rotate under the action of the first rack 8. Under the action of the worm gear 26 and the worm 17, the two sets of rotating placement plates 7 on the top plate 15 will rotate at a certain angle, further presenting all the placement plates to the prison management personnel. At the same time, during the sliding opening of the cover plate 2, the side plate 3 will retract into the interlayer of the cabinet 1 through the action of the bevel gear and the first transmission mechanism 21. During the sliding process, the observation window 28 on the side wall of the side plate 3 will be cleaned, making it convenient for staff to observe the storage of the keys inside from the outside.

[0046] Although embodiments of the present invention have been shown and described, these specific embodiments are merely illustrative of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
