Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 A hazardous chemical storage device includes a box assembly for storing and protecting hazardous chemicals and maintaining internal ventilation, and also includes eight transmission assemblies arranged inside the box assembly for pressing down and tightening by their own weight to provide clamping thrust and can be elastically reset. Four clamping assemblies are evenly installed on the transmission assembly for pushing and buffering the hazardous chemicals from a circumference.

[0026] In this embodiment: the box assembly includes a storage box 101, a box door 102 is arranged in front of the storage box 101, an exhaust pipe 103 is arranged on the top of the storage box 101, a first filter plate 104 is arranged at the bottom of the exhaust pipe 103, an exhaust fan 105 is arranged above the first filter plate 104, two second filter plates 106 are symmetrically arranged on both sides of the storage box 101, two placement plates 107 are evenly arranged in the storage box 101, a waste liquid tray 108 is arranged at the bottom of the storage box 101, the box door 102 is hingedly connected to the storage box 101, and the second filter plate 106 is circular in shape;

[0027] In this embodiment, the transmission assembly includes a bottom plate 201, a telescopic rod 202 is arranged at the center of the bottom plate 201, a first spring 203 is installed outside the telescopic rod 202, a pressing plate 204 is arranged above the first spring 203, four fixed plates 205 are evenly arranged on the circumference of the pressing plate 204, the pressing plate 204 is slidably connected to the fixed plate 205, a pull belt 206 is arranged between the top of the pressing plate 204 and the fixed plate 205, the fixed plate 205 is welded to the bottom plate 201, and the pull belt 206 is arranged between the fixing plate 205 and the bottom plate 201. The belt 206 is made of nylon. The hazardous chemicals are placed on the pressure plate 204 from above. The weight of the hazardous chemicals will drive the pressure plate 204 to slide downward along the fixed plate 205 under the support of the bottom plate 201, pressing down the first spring 203 on the top of the telescopic rod 202. At the same time, the pressure plate 204 drives the four circumferential draw belts 206 to tighten under the support of the fixed plate 205 to provide thrust for clamping. When the hazardous chemicals are taken out, the first spring 203 is released to drive the pressure plate 204 to reset for the next placement.

[0028] In this embodiment: the clamping assembly includes a clamping plate 301, a pad 302 is provided on the clamping surface of the clamping plate 301, a push rod 303 is provided on the side of the clamping plate 301 away from the pad 302, a second spring 304 is installed on the outside of the push rod 303, and a push block 305 is provided on the end of the push rod 303 away from the clamping plate 301. The pad 302 is in the shape of an arc plate and is made of rubber. The side of the push block 305 away from the push rod 303 is an arc surface. When the pull belt is tightened 206, the push block 305 will be pushed to squeeze the second spring 304 and drive the pad 302 on one side of the clamping plate 301 to be close to the hazardous chemicals through the push rod 303, so as to clamp and fix the hazardous chemicals. When the hazardous chemicals are taken out, the second spring 304 is released to drive the clamping plate 301 and the pad 302 to reset for the next clamping.

[0029] Working principle: Hazardous chemicals are placed on the pressure plate 204 from above. The weight of the hazardous chemicals will drive the pressure plate 204 to slide downward along the fixed plate 205 under the support of the bottom plate 201, pressing down the first spring 203 on the top of the telescopic rod 202. At the same time, the pressure plate 204 drives the four circumferential drawstrings 206 to tighten under the support of the fixed plate 205, thereby pushing the push block 305 to squeeze the second spring 304 and drive the pad 302 on one side of the clamping plate 301 to be close to the hazardous chemicals through the push rod 303, thereby clamping and fixing the hazardous chemicals; then close it. The box door 102 and the exhaust fan 105 work to allow external air to enter the storage box 101 after being filtered through the second filter plate 106, and to be discharged after being filtered through the first filter plate 104 in the exhaust pipe 103, thereby maintaining air circulation in the storage box 101, and the leaked waste liquid flows into the waste liquid tray 108 under the placement plate 107 for collection; when the hazardous chemicals are taken out, the first spring 203 is released to drive the pressure plate 204 to return to its original position, and the second spring 304 is released to drive the clamping plate 301 and the pad 302 to return to their original position so as to be fixed next time.
