Description

Technical Field

[0001] This utility model relates to the field of file access technology, specifically to an intelligent file access device with access control function. Background Technology

[0002] In document storage devices, filing cabinets are typically used for storage. For security and privacy reasons, each user is assigned a storage cell and locked. Each person can only use their assigned cell. This storage method takes up a lot of space, and the space in each person's cell is small, resulting in low overall utilization of the storage cabinet.

[0003] To address the issues of large space occupation and low actual space utilization in traditional storage cabinets, Chinese Patent Publication No. CN212546196U discloses a steel filing cabinet with high space utilization. This high-space-utilization steel filing cabinet includes a cabinet body. Two symmetrically positioned air dryers are fixedly connected to the inner bottom wall of the cabinet body. Both inner side walls of the cabinet body have equally spaced slots, each slot containing a movable locking block. The interior of the cabinet body has equally spaced horizontal plates, each with its two sides fixedly connected to the locking blocks. Each horizontal plate has ventilation holes on its upper surface and a slide rail on its upper surface. Each slide rail has equally spaced limiting holes on its inner side wall. This high-space-utilization steel filing cabinet allows for the disassembly and installation of vertical plates via the horizontal slide rails on the horizontal plates and the vertical second slots on the horizontal plates. The slots on the inner side walls of the cabinet body also allow for the disassembly and installation of horizontal plates, thus improving the space utilization of the filing cabinet.

[0004] In the above solution, the vertical plate can be moved left and right on the horizontal plate by a horizontal slide rail on the horizontal plate and a slider on the vertical plate. The left and right movement of the vertical plate can fix documents of different thicknesses and sizes. The vertical plate can be disassembled and installed by a second vertical slot on the horizontal plate and the horizontal plate can be disassembled and installed by a slot on the inner side wall of the filing cabinet body. This improves the utilization rate of the filing cabinet space. However, this method of improving utilization rate compromises the security of the filing cabinet. Moreover, the high frequency of sliding the vertical plate to improve the space utilization of the device is not suitable for most usage scenarios. Therefore, we propose an intelligent file storage and retrieval device with access control function. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides an intelligent file access device with access control functionality, comprising a storage cylinder and a closing mechanism mounted on the storage cylinder. The storage cylinder contains a plurality of isolation components, which are distributed circumferentially at equal intervals within the storage cylinder. The bottom of the storage cylinder rotates relative to the main body of the storage cylinder.

[0006] In some embodiments, a support member and an annular slide rail are provided between the isolation components, and several isolation components are connected by the annular slide rail. A lead screw is provided inside the storage cylinder, and a lifting plate is provided on the lead screw. The lifting plate is threadedly connected to the lead screw, and the support member is slidably connected to the isolation component.

[0007] In some embodiments, the isolation component includes a partition, a lifting groove formed on the partition, a matching slider fixed at both ends of the partition, a conical roller mounted on the matching slider, and a connecting hole formed on the partition. The storage cylinder is symmetrically provided with matching grooves, the matching slider slides in cooperation with the matching grooves, and the two conical rollers rotate in contact with the top and bottom of the inner wall of the storage cylinder, respectively.

[0008] In some embodiments, the supporting component includes a mounting block, a supporting assembly mounted on one side of the mounting block, a lifting slider fixed on the other side of the mounting block, a fixing block disposed on the mounting block, a telescopic block disposed on the fixing block, a turntable disposed on the telescopic block, and a locking block fixed on the turntable. The telescopic block is rotatably connected to the turntable, and the telescopic block can extend and retract relative to the fixing block. The lifting plate has an annular T-shaped groove, the locking block cooperates with the annular T-shaped groove, and the lifting slider cooperates with the lifting slide groove to slide.

[0009] In some embodiments, the closing mechanism includes a rotating column, a torsion spring sleeved on the rotating column, and a sector plate. One end of the torsion spring is fixed to the rotating column. The inner walls and outer surfaces of the two side edges of the sector plate are respectively provided with locking blocks. The number of sector plates is set to a plurality, and the plurality of sector plates are nested and cooperate with each other. The plurality of sector plates are blocked and limited by the locking blocks.

[0010] In some embodiments, the other side of the torsion spring is connected to the sector plate furthest away in the direction of torsion extension.

[0011] In some embodiments, both the load-bearing component and the closing mechanism include a rotating column, a torsion spring, and a sector plate.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. This utility model achieves adaptive adjustment of storage space by setting adjustable isolation components and supporting components to work together. When a file is placed in, the adjacent partitions automatically expand outward according to the thickness of the file and slide stably under the limit of the annular slide rail and the matching slide groove. When empty, the partitions are squeezed and contracted, reducing the ineffective gap. In conjunction with the torsion spring driven fan-shaped plate telescopic structure in the supporting component, the occupied empty area is further compressed, which significantly improves the utilization rate of the internal space of the storage cylinder and solves the problems of space waste and low utilization rate of traditional filing cabinets.

[0014] 2. This utility model adopts a nested fan-shaped plate structure for the closing mechanism, combined with torsion spring drive and rotating column control, to achieve precise adjustment of the opening and closing angle. During storage, only the storage area corresponding to authorized users will rotate to the bottom of the closing mechanism, and the opening and closing degree of the closing mechanism is dynamically adjusted according to the thickness of the file to prevent unauthorized areas from being exposed. During retrieval, the lifting plate is precisely positioned by the screw drive, and the mechanical limit of the locking block and the annular T-shaped groove ensures that only authorized operations can trigger the file to be ejected, realizing the authorization verification of storage and retrieval, and greatly improving the confidentiality of the file.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1-6 The present invention provides a technical solution: an intelligent file storage and retrieval device with access control function, including a storage cylinder 2 and a closing mechanism 1 installed on the storage cylinder 2. The storage cylinder 2 is provided with a plurality of isolation components 34, which are distributed in a circumferentially spaced manner within the storage cylinder 2. The bottom of the storage cylinder 2 rotates relative to the main body of the storage cylinder 2.

[0025] The storage cylinder 2 serves as the main structure of the device, providing a cylindrical space for file storage. The interior is dynamically adjusted to achieve multi-user partitioned storage. The bottom can rotate relative to the main body, driven by a built-in motor, to rotate the storage areas of different users to below the closing mechanism 1, thereby achieving access control isolation. The internal isolation components 34, which are evenly spaced in a circle, divide the storage cylinder 2 into multiple independent storage units. The spacing of the partitions 341 is dynamically adjusted to accommodate files of different thicknesses.

[0026] A bearing component 32 and an annular slide rail 31 are provided between the isolation components 34. Several isolation components 34 are connected by the annular slide rail 31. A lead screw 33 is provided inside the storage cylinder 2. A lifting plate 35 is provided on the lead screw 33. The lifting plate 35 is threadedly connected to the lead screw 33. The bearing component 32 is slidably connected to the isolation component 34.

[0027] The isolation component 34 includes a partition 341, a lifting groove 345 opened on the partition 341, a matching slider 342 fixed at both ends of the partition 341, a conical roller 343 installed on the matching slider 342, and a connecting hole 344 opened on the partition 341. The storage cylinder 2 is symmetrically provided with matching grooves 21. The matching slider 342 slides in cooperation with the matching grooves 21. The two conical rollers 343 contact and rotate with the top and bottom of the inner wall of the storage cylinder 2, respectively.

[0028] The isolation component 34 divides the storage space, enabling dynamic adjustment of the spacing between the partitions 341 to accommodate document thickness. The two sides of the partitions 341 are slidably connected to the sliding grooves 21 inside the storage cylinder 2 via the matching sliders 342. The top and bottom are in contact with the inner wall of the storage cylinder 2 via tapered rollers 343 to reduce sliding friction. The annular slide rail 31 connects each partition 341, providing a horizontal sliding track to ensure the stability of the partitions 341 when they move. The lifting slide 345 cooperates with the lifting slider 321 of the supporting component 32 to achieve a sliding connection between the partitions 341 and the supporting component 32. When a document is stored, the adjacent partitions 341 are squeezed outward by the document and move along the matching slide 21 and the annular slide rail 31. When empty, the partitions 341 are squeezed and contracted by other partitions 341, reducing ineffective spacing and improving space utilization.

[0029] The supporting component 32 includes a mounting block 323, a supporting assembly 322 mounted on one side of the mounting block 323, a lifting slider 321 fixed on the other side of the mounting block 323, a fixing block 324 set on the mounting block 323, a telescopic block 325 set on the fixing block 324, a turntable 326 set on the telescopic block 325, and a locking block 327 fixed on the turntable 326. The telescopic block 325 is rotatably connected to the turntable 326 and can extend and retract relative to the fixing block 324. The lifting plate 35 has an annular T-shaped groove, the locking block 327 cooperates with the annular T-shaped groove, and the lifting slider 321 cooperates with the lifting slide 345 to slide.

[0030] The supporting component 32 supports the document and works with the lifting plate 35 to push and pull the document out. The supporting component 322 has a built-in rotating column 11, torsion spring 12 and sector plate 13, which is the same as the closing mechanism 1. The torsion spring 12 drives the sector plate 13 to extend and retract to adapt to the change in the spacing of the partition 341 and support the bottom of the document. The telescopic block 325 can extend and retract relative to the fixed block 324, pushing the turntable 326 to make the locking block 327 engage with the annular T-shaped groove on the lifting plate 35. When the document is taken out, the telescopic block 325 extends to push the turntable 326, and the locking block 327 engages with the lifting plate 35. The screw 33 drives the lifting plate 35 to rise and push out the document. After the document is taken out, the telescopic block 325 retracts and the locking block 327 disengages from the lifting plate 35, completing the reset.

[0031] The closing mechanism 1 includes a rotating column 11, a torsion spring 12 sleeved on the rotating column 11, and a sector plate 13. One end of the torsion spring 12 is fixed on the rotating column 11. The inner wall and outer surface of both sides of the sector plate 13 are respectively provided with locking blocks 131. The number of sector plates 13 is set to a certain extent. The sector plates 13 are nested and cooperate with each other. The sector plates 13 are blocked and limited by the locking blocks 131.

[0032] The other side of the torsion spring 12 is connected to the sector plate 13 at the farthest point in the torsion extension direction. The closing mechanism 1 controls the opening and closing of the device to realize the authorization verification and physical isolation of the unauthorized area. It consists of a rotating column 11, a torsion spring 12 and a nested sector plate 13. When storing or retrieving files, the built-in motor drives the rotating column 11 to rotate, which drives the torsion spring 12 to contract or expand, thereby controlling the opening and closing angle of the sector plate 13. The size of the sector plate 13 increases sequentially and is nested. The degree of opening and closing is dynamically adjusted according to the thickness of the file. For example, when storing a thicker file, the sector plate 13 unfolds at a larger angle to ensure that only the authorized area is exposed and to prevent unauthorized files from being viewed or accidentally retrieved.

[0033] The lead screw 33 and the lifting plate 35 realize the vertical lifting of the document and accurately position the target document. The lead screw 33 is driven to rotate by the built-in motor, which drives the lifting plate 35 to move up and down along the thread. The annular T-shaped groove on the lifting plate 35 cooperates with the locking block 327 of the bearing component 32. The mechanical limit ensures that only authorized operations can trigger the document to be ejected, thus improving safety.

[0034] The torsion spring 12 provides elastic driving force to realize the automatic opening and closing of the sector plate 13 and the extension and retraction of the bearing assembly 322. In the closing mechanism 1, one end of the torsion spring 12 is fixed to the rotating column 11, and the other end is connected to the farthest sector plate 13. The deformation of the torsion spring 12 is changed by the rotation of the rotating column 11, which drives the sector plate 13 to retract or expand. In the bearing assembly 322, the torsion spring 12 drives the sector plate 13 to extend and retract to adapt to the change in the spacing of the partition 341.

[0035] The conical roller 343 reduces the frictional resistance when the partition 341 slides. It is installed on the matching slider 342 at both ends of the partition 341 and rotates in contact with the top and bottom of the inner wall of the storage cylinder 2, converting sliding friction into rolling friction and ensuring that the partition 341 moves stably and smoothly.

[0036] Through the coordinated operation of the storage cylinder 2 rotating and positioning, the isolation component 34 dynamically adjusting the distance, the closing mechanism 1 controlling access, and the load-bearing component 32 lifting and lowering, the goals of improving space utilization, dynamic distance adjustment, access management, precise opening and closing, and mechanical limit are achieved, solving the problems of space waste and low security of traditional filing cabinets.

[0037] Example 2:

[0038] Based on Embodiment 1, this utility model provides a technical solution: an intelligent file access device with access control function, wherein the supporting component 322 and the closing mechanism 1 both include a rotating column 11, a torsion spring 12 and a sector plate 13;

[0039] When a document is placed into the device, the built-in motor drives the rotating column 11 in the closing mechanism 1 to rotate to a certain angle. The rotating column 11 drives the torsion spring 12 to elastically contract. The other side of the torsion spring 12 drives the smaller fan-shaped plate 13 on it to contract towards the adjacent larger fan-shaped plate 13. The size of the fan-shaped plates 13 increases sequentially and can be nested together. Driven by the torsion spring 12, all the fan-shaped plates 13 contract into the largest fan-shaped plate 13, thus completing the opening of the device.

[0040] At this time, the document is placed between two adjacent partitions 341 inside the storage cylinder 2. If a large number of documents are placed, the two adjacent partitions 341 will move outward. Since the sliding block 342 and the sliding groove 21 cooperate to slide, and the connecting hole 344 of the partition 341 is slidably connected to the annular slide rail 31, the partition 341 will slide stably under the limiting action of the sliding groove 21 and the annular slide rail 31 when it moves outward. At this time, the bearing component 322 at the bottom of the document will extend and expand between several fan-shaped plates 13 under the drive of the torsion spring 12 after losing the squeezing force of the two adjacent partitions 341. After the document is placed, the built-in motor on the closing mechanism 1 reverses and drives the closing mechanism 1 to close. At this time, the bottom of the storage cylinder 2 rotates under the drive of the built-in motor, storing the placed documents in the preset position and rotating the two empty partitions 341 to the corresponding position under the closing mechanism 1 for the next person to store.

[0041] When retrieving a file, the bottom of storage cylinder 2 will rotate according to each person's storage information, rotating the corresponding person's file under the closing mechanism 1. Since the thickness of each person's stored file is different, the closing mechanism 1 will open and close to different degrees according to the data when the file was put in, in order to protect the safety of other people's files.

[0042] When the document is removed, the telescopic block 325 on the fixed block 324 of the supporting component 32 below the document extends and pushes the turntable 326 and its locking block 327 into the annular T-shaped groove on the lifting plate 35. Then, the turntable 326 rotates under the drive of the built-in motor, so that the locking block 327 engages with the annular T-shaped groove. At this time, the built-in motor drives the lead screw 33 to rotate, and the lead screw 33 drives the lifting plate 35 on it to rise, pushing the document out of the storage cylinder 2. After the document is removed, the turntable 326 and the telescopic block 325 move in opposite directions in sequence, so that the supporting component 32 disengages from the lifting plate 35, completing the removal of the document.

[0043] Due to the limited space inside the storage cylinder 2, the empty partitions 341 are compressed by other partitions 341, which will compress the torsion spring 12 in the bearing component 322 at that position to shrink, thereby reducing the distance between the empty partitions 341 and improving the space utilization rate inside the storage cylinder 2.
