Technical Field
[0001] This utility model relates to the technical field of chemical reagent experimental equipment, specifically a reagent sealed storage tank with a leak-proof structure. Background Technology
[0002] Chemical reagents, or simply reagents, are substances used for chemical research and component analysis. They are elements, compounds, or mixtures with a certain purity standard. They are widely used in chemical experiments, chemical analysis, chemical research, and other experiments. Because most reagents are volatile, they need to be sealed and stored when not in use to prevent them from evaporating into the air and causing harm to the human body during long-term storage.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] Most existing sealed storage containers are not designed with leak-proof features, which makes the caps susceptible to corrosion or aging after prolonged use, leading to leaks. Furthermore, the leak-proof design of some containers makes it difficult to pour out reagents and handle them, posing certain safety risks. Utility Model Content

[0009] The reagent container includes a base, with symmetrically arranged locking blocks on the outer side wall of the base. The top of the base is fixedly connected to the bottom of the inner container. The outer side wall of the inner container is symmetrically arranged with handles. The outer side wall of the inner container is movably connected to the inner side wall of the sealing cap. A second sealing strip is provided inside the sealing cap.
[0010] More preferably, the number of support legs is three, and the three support legs are evenly distributed at the bottom of the tank.
[0011] More preferably, a cavity is formed between the interior of the tank and the filter plate, the leakage absorption layer is disposed in the cavity, the rotating retaining ring has symmetrically formed retaining grooves on its side wall, and the insert box has a retaining groove that matches the retaining strip inside.
[0012] More preferably, the cover has a movable groove, and there are two locking strips distributed on both sides of the rotating gear. Each of the two locking strips has external teeth on one side of its outer wall.
[0013] More preferably, the rotating gear is disposed between the two locking strips, the two locking strips are connected to the rotating gear by external teeth, and the two locking strips and the rotating gear are installed in the movable groove of the cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] Chemical reagents are stored inside the inner container, which is double-sealed by the sealing cap and the lid body to ensure that the chemical reagents are unlikely to leak to the outside. When the chemical reagents leak from the inner container, the container body and the lid form a double seal to protect the reagents from leaking to the outside. The leaked liquid and volatile gas are absorbed by the leak absorption layer through the filter plate, reducing the amount of reagent leakage. The separate design of the inner container and the container body makes it more convenient to take out the reagents and reduces the safety risks when the reagents are poured out.
