During use, the hazardous chemicals cabinet can lock and fix the cabinet door 2 through the setting of the RFID identification device 4 to prevent the cabinet door 2 from being opened at will by unauthorized persons, thereby greatly improving the overall protection performance of the hazardous chemicals cabinet and improving the safety of hazardous chemicals storage.
[0032] Reference Figure 3 and Figure 4The weighing mechanism 5 includes a multi-stage electric push rod 51, a horizontal plate 52 and an electronic scale 53. The multi-stage electric push rod 51 is fixed on one side of the inner wall of the cabinet 1, the horizontal plate 52 is fixed to the output end of the multi-stage electric push rod 51, and the electronic scale 53 is fixed on the top of the horizontal plate 52. More specifically, during use, when the stored hazardous chemicals need to be weighed, the multi-stage electric push rod 51 can be started, and the output end of the multi-stage electric push rod 51 drives the horizontal plate 52 to move to the outside of the cabinet 1, and drives the electronic scale 53 to move to the outside of the cabinet 1 together. Through the arrangement of the multi-stage electric push rod 51, the horizontal plate 52 and the electronic scale 53, it is convenient for the staff to weigh and record the weight data of the stored hazardous chemicals, which is beneficial for the staff to manage the relevant information of the stored hazardous chemicals, thereby improving the practicality of the hazardous chemicals cabinet.
[0033] Reference Figure 2 and Figure 3 The bottom of the inner wall of the cabinet 1 is provided with guide grooves 6 in pairs, and the bottom of the cross plate 52 is fixed with support rails 7 in pairs, and the support rails 7 are slidably connected to the inner wall of the guide groove 6. More specifically, through the setting of the guide groove 6 and the support rail 7, the cross plate 52 and the electronic scale 53 can be auxiliary supported and guided, so that the weighing assembly is more stable during the movement, thereby greatly improving the stability of the weighing assembly during use.
[0034] Reference Figure 1 A handle 8 is fixed to the surface of the cabinet door 2, and a soft cover 9 is provided on the handle 8. More specifically, the handle 8 can facilitate the staff to push and pull the cabinet door 2. At the same time, the setting of the soft cover 9 can improve the comfort of the user's hands when pushing and pulling.
[0035] Reference Figure 2 A plurality of fixings 10 are arranged on the push-pull storage rack 3, and a warning sign 11 is arranged on the surface of the cabinet door 2. More specifically, through the arrangement of the fixings 10, the hazardous chemicals placed inside the storage slot on the push-pull storage rack 3 can be fixed, thereby improving the stability of the hazardous chemicals during storage.

[0037] Working principle: During use, first, the authorized staff can bring the access card close to the RFID card reader 41. When the RFID card reader 41 reads and recognizes that the identity information in the access card is correct, the RFID card reader 41 will send the processing result to the access control controller 42. The access control controller 42 will execute the power-off command according to the processing result. At this time, the electromagnet 43 is powered off and loses suction, so that the iron plate 44 falls off the electromagnet 43, thereby releasing the lock on the cabinet door 2, and then the cabinet door 2 is opened through the handle 8. At the same time, during the storage process, when the stored hazardous chemicals need to be weighed, the multi-stage electric push rod 51 can be started. The output end of the multi-stage electric push rod 51 drives the cross plate 52 to move to the outside of the cabinet 1, and drives the electronic scale 53 to move to the outside of the cabinet 1. Through the arrangement of the multi-stage electric push rod 51, the cross plate 52 and the electronic scale 53, it is convenient for the staff to weigh and record the weight data of the stored hazardous chemicals. After the hazardous chemicals are weighed, The staff pulls out the push-pull storage rack 3 and places the hazardous chemicals into its storage slot, and finally closes the cabinet door 2 to make the iron plate 44 and the electromagnet 43 magnetically attracted to each other to achieve the effect of locking the door. The hazardous chemicals cabinet can lock and fix the cabinet door 2 through the setting of the RFID identification device 4 to prevent the cabinet door 2 from being opened at will by unauthorized people, greatly improving the overall protection performance of the hazardous chemicals cabinet, thereby improving the safety of hazardous chemicals storage, and during the storage process, through the setting of the weighing mechanism 5, it is convenient for the staff to weigh and record the weight data of the stored hazardous chemicals, which is beneficial for the staff to manage the relevant information of the stored hazardous chemicals, thereby improving the practicality of the hazardous chemicals cabinet, and solving the problem that the current hazardous chemicals cabinet has insufficient protection performance, thereby reducing the safety of hazardous chemicals storage, and it is inconvenient for workers to record the weight data of the stored hazardous chemicals, which is not conducive to the workers to manage the relevant information of the hazardous chemicals.
[0038] It should be noted that the RFID identification device 4 in this solution is an existing conventional technical means, which is currently widely used. It can control the access control system through the wireless radio frequency identification technology RFID. The specific implementation method will not be elaborated here.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
