Technical Field

[0001] The present invention relates to the technical field of article storage, and in particular to an escort equipment cabinet with intelligent key matching. Background Art

[0002] After a security company takes on the ATM clearing and cash refilling business, the bank ATM branches and ATM machine keys are centrally managed by the security company. The security team collects and returns the keys upon departure, collecting them from the security team and returning them after completing their mission. Due to the large number of ATM branches and the multiple keys at each branch, the key handover and verification process during the security team's collection and return relies entirely on manual counting and verification, which is labor-intensive and time-consuming. This can lead to incomplete verification and poses certain security risks. In summary, based on the actual situation of ATM key management at the security company, the need for an ATM key management system based on the Internet of Things (IoT) is proposed. By combining information technology with the IoT, the system aims to assist personnel in verifying the legitimacy and counting of ATM keys during the collection and return process.

[0033] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0034] Example 1:

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown, the escort equipment cabinet with smart matching keys in this embodiment includes a cabinet body 1, a placement box 2 arranged in the cabinet body 1, and an identification module 3 arranged on the cabinet body 1. The cabinet body 1 is provided with a window 11; the placement box 2 includes a box body 21, a placement piece 22, a protective piece 23 and a driving piece 24. The box body 21 is arranged on the inner side of the window 11, and the box body 21 has an opening 211 corresponding to the window 11; the placement piece 22 is rotatably arranged in the box body 21, and the placement piece 22 has a placement groove 221; the protective piece 23 is sleeved on the placement piece 22, and the protective piece 23 is provided with a through-hole 231; the driving piece 24 is arranged in the box body 21, and the driving piece 24 is used to guide the placement piece 22 and the protective piece 23 to rotate coaxially in opposite directions so that the placement groove 221, the opening 211 and the window 11 correspond.

[0036] The identification module 3 includes but is not limited to a scanning device for identifying key information. When in use, after the information of the key to be obtained is identified by the identification module 3, the main controller controls the corresponding placement box 2 to open, wherein the driving member 24 is started, causing the placement member 22 and the protective member 23 to rotate relative to each other. Before this, the placement slot 221 of the placement member 22, the through hole 231 of the protective member 23 and the opening 211 of the box body 21 are evenly distributed and correspond to each other, so that the key placed in the placement slot 221 can be properly kept. When the driving member 24 is started, the placement member 22 and the protective member 23 rotate in the box body 21, so that the placement slot 221, the through hole 231, the opening 211 and the window 11 are all corresponding to each other, so that the key in the placement slot 221 is exposed, and then the key-taking staff can take the key out of the placement slot 221 through the window 11, thereby effectively improving the security of the key. At the same time, when the key is kept, the placement slot 221 is located at the innermost side of the box body 21 and cannot be opened by violent means outside the cabinet body 1, further improving the security of the key.

[0037] In this embodiment, the key is placed in the placement member 22. Only after successful identification can the corresponding driving member 24 be driven to rotate the placement member 22 and the protective member 23 relative to each other, so that the staff who takes the key can take the key out of the placement slot 221 through the window 11, and the key is more secure.

[0038] like Figure 10 As shown, the placement member 22 includes a rotating column 222 and an end plate 223. The rotating column 222 is rotatably arranged in the box body 21. A groove extending along its axial direction is provided on the circumferential surface of the rotating column 222. The end plate 223 is coaxially and fixedly arranged at both ends of the rotating column 222 and forms a placement groove 221 with the groove. The outer end of the end plate 223 is provided with a fixed shaft 224 coaxial therewith. The fixed shaft 224 passes through the box body 21 and is rotatably connected therewith. The fixed shaft 224 is transmission-connected to the driving member 24.

[0039] By rotatably setting the rotating column 222 in the box body 21, when the driving member 24 is started, the driving member 24 can drive the fixed shaft 224 to rotate on it relative to the box body 21, and then drive the rotating column 222 to rotate in the box body 21, so that the slot can rotate in the box body 21. At the same time, the fixed shaft 224 and the protective member 23 are coaxially driven in the opposite direction, so that the protective member 23 can rotate in the box body 21 in the opposite direction to the rotating column 222, so that the slot and the through port 231 can both correspond to the opening 211, so that the staff can take the key out of the placement slot 221 through the window 11.

[0040] like Figure 10As shown, the protective member 23 includes a rotating cylinder 232 and an end ring 233. The rotating cylinder 232 is coaxially rotatably arranged on the outer circumferential surface of the rotating column 222. The through port 231 is located on the rotating cylinder 232. The end ring 233 is coaxially fixedly arranged at both ends of the rotating cylinder 232 and located at both ends of the rotating column 222. The end ring 233 is coaxially reversely driven with the fixed shaft 224.

[0041] By coaxially sleeved the rotating cylinder 232 on the rotating column 222, and coaxially fixedly arranged the end rings 233 at both ends of the rotating cylinder 232, when the end rings 233 are connected to the fixed coaxial reverse transmission, and the driving member 24 guides the fixed shaft 224 to rotate on the box body 21, the end rings 233 can drive the rotating cylinder 232 to rotate in the opposite direction outside the rotating column 222, so that the placement groove 221 and the through port 231 can both correspond to the window 11.

[0042] like Figure 7 As shown, the placement box 2 also includes a coaxial reverse transmission member, which includes an inner gear ring 251, planetary gears 252 and a sun gear 253. The inner gear ring 251 is coaxially fixedly arranged on the inner circumferential surface of the end ring 233 at one end of the rotating cylinder 232, and the planetary gears 252 are rotatably arranged on the inner side of the box body 21 through a pin shaft. The sun gear 253 is coaxially fixedly arranged on the fixed shaft 224 at one end of the rotating column 222. The planetary gears 252 are located in the inner gear ring 251 and meshed with it, and the sun gear 253 and the planetary gears 252 are meshed.

[0043] When the driving member 24 is started, the driving member 24 can drive the fixed shaft 224 to rotate on the housing 21, and the inner gear ring 251, the planetary gear 252 and the sun gear 253 are engaged with each other, so that the rotation direction of the end ring 233 and the fixed shaft 224 is opposite. At the same time, during the torque transmission process, the rotation speed of the end ring 233 is lower than the rotation speed of the fixed shaft 224, so that when the placement groove 221 is located on the inner side of the housing 21, the through port 231 is also located on the inner side of the housing 21 and does not correspond to the placement groove 221. Then, after the rotating column 222 and the rotating cylinder 232 rotate coaxially in opposite directions, the placement groove 221 and the through port 231 correspond to each other on the inner side of the opening 211, so as to facilitate the removal of the key.

[0044] like Figure 7As shown, the driving member 24 includes a servo motor 241, a first rotating shaft 242, a second rotating shaft 243, a first bevel gear 244, a second bevel gear 245, a worm gear 246 and a worm 247. The first rotating shaft 242 and the second rotating shaft 243 are vertically rotatably arranged in the housing 21. The first bevel gear 244 is coaxially fixedly arranged at the inner end of the first rotating shaft 242. The outer end of the second rotating shaft 243 is synchronously driven and connected with the fixed shaft 224. The second bevel gear 245 is coaxially fixedly arranged at one end of the second rotating shaft 243. The first bevel gear 244 and the second bevel gear 245 are meshed. The worm gear 246 is coaxially fixedly arranged at the other end of the second rotating shaft 243. The worm 247 is meshed with the worm gear 246 and rotatably arranged in the housing 21. The servo motor 241 is arranged in the housing 21, and the output shaft of the servo motor 241 is coaxially fixedly connected to the worm 247.

[0045] When in use, the servo motor 241 is started, and the output shaft of the servo motor 241 drives the worm 247 to rotate, and then the worm 247 drives the second rotating shaft to rotate. Because the first bevel gear 244 and the second bevel gear 245 are engaged with each other, the torque is transmitted to the first rotating shaft 242, and the outer end of the second rotating shaft 243 is synchronously connected with the fixed shaft 224, so that the fixed shaft 224 can drive the rotating column 222 to rotate in the box body 21. Because the worm 247 can drive the worm wheel 246 to rotate, and the worm wheel 246 cannot drive the worm 247 to rotate, when the placement slot 221 is located in the box body 21 to keep the key, the protective member 23 or the placement member 22 cannot be moved through the opening 211 to rotate in the box body 21.

[0046] like Figure 6 As shown, teeth are provided on the outer circumferential surface of the end ring 233 along its circumference, and the placement box 2 also includes a gate plate 261, which is slidably provided on the inner side of the opening 211 along the vertical direction, and the inner side of the gate plate 261 is provided with teeth and grooves arranged at equal intervals along the vertical direction, and the teeth and the teeth and grooves are engaged.

[0047] By providing teeth arranged along the circumference of the end ring 233, and providing a gate plate 261 that can slide in the vertical direction on the inner side of the opening 211, the tooth grooves on the gate plate 261 are engaged with the teeth. When the end ring 233 rotates in the box body 21, the gate plate 261 can be lowered in the vertical direction on the inner side of the opening 211 through the meshing action, so that the opening 211 can be opened, further improving the security of the key while preventing external pollution from eroding the internal structure of the box body 21 through the opening 211.

[0048] like Figure 5As shown, the placement box 2 also includes a positioning rod 262 and a first spring 263. The positioning rod 262 is fixedly arranged in the box body 21 along the vertical direction. The positioning rod 262 passes through the gate plate 261 along the vertical direction and slides with it. The first spring 263 is sleeved on the positioning rod 262. The two ends of the first spring 263 respectively abut the bottom end of the gate plate 261 and the bottom end of the inner cavity of the box body 21.

[0049] The positioning rod 262 is fixedly arranged in the box body 21 in the vertical direction, so that the positioning rod 262 passes through the gate plate 261 in the vertical direction and slides with it, and the first spring 263 is sleeved on the positioning rod 262, so that the gate plate 261 needs to overcome the elastic force of the first spring 263 when descending, thereby making the gate plate 261 more stable during the sliding process and preventing the gate plate 261 from moving directly downward.

[0050] like Figure 8 and Figure 9 As shown, the placement box 2 also includes a locking member, which includes a fixing plate 271, a fixing ring 272, a clamping disc 273, a second spring 274 and an electromagnet 275. The fixing plate 271 is set on the side of the box body 21. One side of the fixing plate 271 is provided with a connecting rod 277 extending in the horizontal direction and fixedly connected to the box body 21. The fixing ring 272 is coaxially fixedly provided at one end of the fixed shaft 224. The circumferential surface of the fixed shaft 224 is provided with a groove extending in its radial direction. The clamping disc 273 and the fixing ring are fixedly provided. 272 is coaxially slidably arranged on the connecting rod 277, and a limit block 276 that can be inserted into the slot is provided on the side of the clamping disk 273 facing the fixed ring 272. The second spring 274 is sleeved on the connecting rod 277, and the two ends of the second spring 274 respectively abut against the opposite sides of the clamping disk 273 and the fixed plate 271. The electromagnet 275 is arranged on the inner side of the fixed plate 271 and its working end faces the clamping disk 273. The clamping disk 273 can guide the lowering limit block 276 to withdraw from the slot under the attraction of magnetic force.

[0051] The locking member can lock the fixed shaft 224 with the box body 21, so as to prevent the placement member 22 from rotating due to external force in the power-off state. When the placement member 22 stores the key, the clamping plate 273 is away from the fixing plate 271 under the action of the second spring 274, so that the limit block 276 can be axially clamped in the slot of the fixing ring 272, and the fixing ring 272 is coaxially fixedly arranged at one end of the fixed shaft 224, so that the fixed shaft 224 cannot break through the limit of the limit block 276 and rotate. When the key is to be taken out, the electromagnet 275 is energized, so that The clamping plate 273 is attracted by the magnetic force and slides on the connecting rod 277. At the same time, the limit block 276 withdraws from the slot of the fixing ring 272, so that the fixing ring 272 can rotate relative to the box body 21, and then the fixed shaft 224 can slide on the box body 21. When the placement groove 221 moves to the inner side of the box body 21, the clamping plate 273 allows the limit ring to be reinserted into the slot under the action of the second spring 274, thereby re-locking the fixed shaft 224, thereby preventing the placement piece 22 from being rotated by external force, further improving the safety of the key.

[0052] Example 2:

[0053] Compared with Example 1, Figure 4 As shown, in this embodiment, a first protective cover 212 is further provided on one side of the box body 21, and the cover is arranged on the outside of the fixed shaft 224 and the first rotating shaft 242. By providing the first protective cover 212 on the outside of the box body 21, it is impossible to move the fixed shaft 224 outside the box body 21 to cause the placement piece 22 to rotate in the box body 21, thereby further improving the safety of the placement box 2.

[0054] like Figure 8 As shown, a second protective cover 213 is also provided on the outside of the box body 21, and the cover is provided on the outside of the locking member. By providing the second protective cover 213 on the outside of the box body 21, the locking member cannot be released from the fixed shaft 224 by external force in the second protective cover 213, thereby further improving the security of the key in the placement slot 221.
