[0006] A control module, a wireless communication module and a power supply module for supplying power to various electrical components are installed in the box. An identity recognition system is set on the outer wall of the box. The control module is respectively connected to the humidity sensor, temperature sensor, air pressure sensor, exhaust fan, control valve, identity recognition system and locking mechanism. The control module is connected to the remote management terminal through the wireless communication module.

[0007] Furthermore, an elastic rubber pad layer is provided in the through hole of the limiting plate, and the arc-shaped parts of the first and second clamping rings are covered with the elastic rubber pad layer.

[0008] Furthermore, the storage partition is provided with a weighing module and an information identification module for identifying hazardous chemicals information. The weighing module and the information identification module are both connected to the control module. The control module transmits the obtained weighing information and hazardous chemicals information to the remote management terminal through the wireless communication module. The hazardous chemicals information includes the name, batch, source, storage time, packaging bottle number, storage weight, management level, shelf life and other information of the hazardous chemicals, which is convenient for monitoring and tracing the entire process of storage, issuance, return to storage and cancellation of each bottle of hazardous chemicals, and also has a recording function to prevent data loss.

[0009] Furthermore, the support rod is a screw rod, the limiting plate is slidably installed on the support rod through a connecting hole, and positioning nuts are respectively provided on the upper and lower surfaces of the limiting plate on the support rod.

[0011] Furthermore, the locking structure includes a strip through groove arranged at the top of the strip slot, a short rod for easy handholding is passed through the strip through groove, a compression plate is fixedly connected to the lower end of the short rod, and a spring in a compressed state is provided between the straight plate sections at both ends of the snap ring one and the snap ring two and the compression plate. The spring in the compressed state rebounds, so that the compression plate is pressed against the strip slot, and the snap ring one and the snap ring two are firmly pressed against the limit plate, thereby achieving the fixation of the snap ring one and the snap ring two. The relative positions of the snap ring one and the snap ring two on both sides of the through hole can be adjusted according to the size of the hazardous chemical reagent bottle. During adjustment, the short rod is held and pressed down to eliminate the pressure between the compression plate and the strip through groove, push the snap ring one and the snap ring two to the appropriate position, and the short rod is released to lock the snap ring one and the snap ring two.

[0012] Furthermore, there are four support rods, of which the support rods located on the left and right sides are telescopic rods, the limit plate is installed on the top of the movable end of the telescopic rod, and the other two support rods located on the front and rear sides are guide rods.

[0015] In the present invention, the humidity sensor, temperature sensor and air pressure sensor measure the data information of the humidity, temperature and air pressure in the box and transmit the information to the control module. When the humidity, temperature or air pressure reaches the preset threshold value, the control module issues a command to control the exhaust fan and the control valve to ventilate and extract air until the environment in the box meets the preset humidity, temperature and air pressure values. The control module controls the exhaust fan and the control valve to shut down. When the experimenter takes the hazardous chemicals, he needs to receive the unlocking command through the identity recognition system set on the outer wall of the box. After the identity recognition is passed, the control module controls the opening and locking of the locking mechanism. The control module can transmit the humidity, temperature, air pressure values ​​in the box and the hazardous chemical access information it obtains to the remote management terminal through the wireless communication module for recording and tracing. The storage platform is provided with multiple rows of storage partitions for placing hazardous chemical reagent bottles. The storage partitions are used to place hazardous chemical reagent bottles. The installation height of the limit plate on the support rod is adjusted according to the height of the hazardous chemical reagent bottles. The installation height of the limit plate is adjusted so that it is not higher than the bottleneck position of the lowest hazardous chemical reagent bottle stored in the box. Since a through hole that can accommodate the hazardous chemical reagent bottle with the largest diameter stored in the box is opened on the limit plate corresponding to each storage partition position, it can adapt to the different sizes of hazardous chemical reagent bottles placed on the storage partition, so that hazardous chemical reagent bottles of different sizes can be inserted into the through hole, and the clamping positioning structure provided on the limit plate corresponding to each through hole position is used to prevent the hazardous chemical reagent bottle from shaking and tipping over. Since the straight plate sections of the clamp ring 1 and the clamp ring 2 can be slidably connected in the strip-shaped slot, the clamp ring 1 and the clamp ring 2 can be moved according to the diameter of the hazardous chemical reagent bottle so that their arc-shaped parts are wrapped around the outside of the hazardous chemical reagent bottle. In order not to affect the weighing of the weighing module, the clamp ring 1 and the clamp ring 2 do not touch each other with the hazardous chemical reagent bottle, leaving a certain gap. The locking structure installed between the strip-shaped slot and the clamp ring 1 and the clamp ring 2 is used to lock them to prevent them from being displaced after collision or abutment with the hazardous chemical reagent bottle.

[0016] Beneficial effects: The utility model has a compact structure and can be used to store hazardous chemical reagent bottles of different sizes, so that the reagent bottles remain stable during storage, retrieval or box movement, preventing them from tipping over and avoiding collisions. At the same time, the temperature, humidity, pressure and other parameters of the storage environment can be monitored to achieve real-time monitoring and data transmission of the safety status of hazardous chemicals and storage environment conditions.
