If the leaked chemicals come into contact with other leaked chemicals, they may cause serious safety accidents. Therefore, the safety of the storage needs to be improved. In order to solve the above-mentioned problems, a hazardous chemical storage cabinet is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a hazardous chemical storage cabinet in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: A hazardous chemical storage cabinet includes a storage cabinet for hazardous chemicals. The storage cabinet has a shaft inside. The upper end of the shaft is rotatably connected to an upper shaft seat, which is fixedly installed on the top of the inner cavity of the storage cabinet. The lower end of the shaft is rotatably connected to a lower shaft seat, which is fixedly installed on the bottom of the inner cavity of the storage cabinet. The lower outer wall of the upper shaft seat is threaded with a locking bolt that abuts against the shaft. Several mounting plates are fixedly installed on the shaft from top to bottom. Several threaded holes are opened around the mounting plates. A placement tube is threadedly connected to the threaded hole. The upper outer wall of the placement tube is constructed with a limiting protrusion ring. The placement tube contains capped test tubes containing hazardous chemicals. A cap is threadedly connected to the upper part of the placement tube.

[0006] In a preferred embodiment, the spacing between adjacent mounting discs is such that the placement tube can be removed while the cap is on.

[0007] In a preferred embodiment, an annular sealing gasket is provided at the connection between the cap and the limiting protrusion, and the annular sealing gasket is fitted onto the placement tube.

[0008] In a preferred embodiment, the storage cabinet is fixedly mounted with feet on both sides of its bottom.

[0009] In a preferred embodiment, the storage cabinet has a door on its front side, and the door is hinged to the storage cabinet.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, test tubes containing hazardous chemicals can be placed in a sealed space composed of a placement tube and a sealing tube in the storage cabinet. In this way, when the test tube leaks chemicals due to installation or aging, the sealed space composed of the placement tube and the sealing cap can prevent the spread of hazardous chemicals and avoid contact and reaction with other leaked chemicals, thus avoiding safety risks. This greatly improves the safety of storing hazardous chemicals.

[0012] 2. In this utility model, when it is discovered that the test tube inside the placement tube is leaking hazardous materials, personnel can rotate the placement tube to directly remove it from the threaded hole on the mounting plate with the cap on, thereby carrying out separate post-processing and improving the safety of post-processing.

[0013] 3. In this utility model, the position of the shaft is locked by rotating the locking bolt, so that the position of the mounting plate can be locked when it is not rotated and removed, thereby preventing the mounting plate from rotating due to handling or contact vibration, which would cause serious shaking and collision damage to the internal test tubes.
