Description

Technical Field

[0001] This utility model relates to the field of intelligent reagent cabinet technology, and in particular to an RFID-based intelligent medicine reagent cabinet. Background Technology

[0002] Utility model CN211711467U relates to the field of reagent cabinet technology and discloses an RFID-based intelligent reagent cabinet. The cabinet includes a main body with a base fixedly connected to its bottom. Sliding grooves are formed on the inner walls of both sides of the base, and four floor mats are fixedly connected to the bottom of the base. This RFID-based intelligent reagent cabinet incorporates a rotary motor, transmission rod, transmission gear, rotary bearing, rotary screw, and driven gear internally in the base. The transmission gear rotates using the power of the rotary motor and transmission rod, which in turn drives the rotary screw. A movable shaft is threaded onto the external part of the rotary screw, and a lifting plate is mounted on its exterior. The lifting plate is movably connected to the base via a slider and a sliding groove, allowing the movable shaft to move up and down on its exterior via the rotation of the rotary screw, thus raising and lowering the lifting plate. The slider and sliding groove ensure stable movement.

[0003] While existing reagent cabinets can reduce evaporation through sealed storage, in laboratory environments, reagent bottles need to be frequently opened and closed for storage. Over time, the sealing performance may deteriorate, leading to the accumulation of trace amounts of evaporation. Furthermore, existing technologies lack real-time monitoring methods for evaporation, making it difficult to detect leaks or abnormal evaporation in a timely manner. Moreover, existing technologies are easily affected by ground unevenness during movement, causing vibrations that make the reagents inside the cabinet shake and sway, which is not conducive to reagent storage and is also detrimental to internal electrical components. Therefore, an RFID-based intelligent reagent cabinet is needed to meet these requirements. Utility Model Content

The diameter of the through hole 19 is larger than the maximum outer diameter of the first connecting frame 7, the second connecting frame 9 and the moving wheel 10 rotating around the pivot 16, so as to provide lifting space and horizontal rotation space for the first connecting frame 7, the second connecting frame 9 and the moving wheel 10.

[0023] Specifically, in this embodiment, a threaded hole 20 is provided in the sleeve 11, and the screw 12 is threadedly fitted into the threaded hole 20 to realize the connection between the sleeve 11 and the screw 12, and the rotation of the screw 12 realizes the corner lifting and lowering adjustment of the main body 1 of the device.

[0024] Specifically, in this embodiment, a hemispherical hole 21 is provided on the top of the pad 15, and the ball shaft 14 is located inside the hemispherical hole 21. The diameter of the opening of the hemispherical hole 21 is smaller than the diameter of the ball shaft 14, so as to provide space for the ball shaft 14 to move.

[0025] Specifically, in this embodiment, two horizontal bubbles 22 are provided on the outer wall of the device body 1.
