Abstract
Description
Technical Field
[0001] This utility model relates to the field of file cabinet technology, and in particular to an RFID file cabinet with weighing function. Background Technology
[0002] RFID file cabinets with weighing capabilities are innovative intelligent devices that integrate radio frequency identification (RFID) technology and weighing systems. Their working principle is as follows: RFID tags are affixed to each document or file box, storing detailed information such as the document name, number, category, and storage location. The cabinet is equipped with an RFID reader / writer; when documents enter or leave the cabinet, the reader / writer automatically and quickly captures the RFID tag information and transmits the data to the connected management system in real time. Simultaneously, the file cabinet uses high-precision weighing sensors to accurately measure the weight of each document or file box, and this weight data is also synchronously fed back to the management system. This innovative design makes document management more efficient and accurate, and is widely applicable to various scenarios with stringent document management requirements. In corporate offices, it helps to quickly find important contract documents, monitor document borrowing and return in real time, and even determine whether documents have been privately split or replaced based on weight changes. In the library sector, it enables effective management of valuable books, facilitating borrowing and searching for readers and preventing theft or damage. In archives management departments, it can accurately track the flow of archives, ensuring the integrity and security of archival information.
[0003] A search revealed Chinese Patent Publication No. CN204292558U, which discloses an RFID smart file cabinet capable of precise area positioning. The cabinet mainly comprises a cabinet body and a door. Inside the cabinet body are a power unit, one or more data acquisition units, and storage units. A main control unit is installed on the door. The main control unit communicates with the data acquisition units via a bus. Each data acquisition unit connects to one or more storage units. Each storage unit has a box structure, including inner and outer plastic partitions and a shielding shell. At least one antenna is symmetrically installed vertically or horizontally within the interlayer of the plastic partitions and the shielding shell. The radio frequency chip and radio frequency port of the data acquisition unit are connected to the antenna of the storage unit. The advantages of this invention are: using RFID technology, leveraging wireless positioning, non-contact, and automatic batch identification characteristics, it improves the informatization level and work efficiency of file management, achieves on-site supervision, and prevents loss and leakage. However, because the spacing between the partitions is fixed, some files cannot be stored, thus narrowing the scope of application and making it inconvenient to use. Utility Model Content

A password module 8 is installed in the middle of the right side of the cabinet door 7.
[0040] Specifically, by applying pressure to the inward side of the hemisphere 205, the spring 204 will be subjected to compressive force, causing the hemisphere 205 to gradually disengage from the locking groove 207 of the partition 206, thereby releasing the locking state between the upright 201 and the partition 206. The partition 206 can move freely on the upright 201. When the partition 206 reaches the preset position, the spring 204 will release its stored elastic potential energy and push the hemisphere 205 to re-engage into the locking groove 207 of the corresponding height to fix the position of the partition 206, thereby expanding the usability of the partition 206.
