[0006] The sealing mechanism comprises a cover plate, and the upper surface of the sealing column is provided with the cover plate; that is, the cover plate provides sealing stability for the sealing column, thereby avoiding gas leakage.

[0007] The sealing mechanism includes a rack plate and a slide groove. Two slide grooves are arranged in the sealing column. A rack plate is arranged in the slide groove. A top column is arranged at the end of the rack plate. Two holes are arranged on the inner wall of the sealing tank one. The top column is installed in cooperation with the holes; that is, the top column cooperates with the holes of the sealing tank one so that the top column enters the holes, thereby avoiding the loosening of the internal and external threads due to long-term storage.

[0008] The sealing mechanism includes a driving rod and a gear. The driving rod is arranged inside the sealing column, and a gear is arranged at the end of the driving rod. The gear is meshed with the rack plate; that is, the gear provides a transmission function for the rack plate, thereby facilitating the movement of the rack plate.

[0009] The sealing mechanism comprises a driving disc, and the end of the driving rod is provided with the driving disc; that is, the driving disc provides driving force for the driving rod.

[0010] A push block is arranged on the upper surface of the cover plate; that is, the push block is fixed on the cover plate to assist the opening of the cover plate.

[0012] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0013] 1. Put the chemical substances into sealed tank 2, and then the personnel will align the sealing column and the sealing plug with the inner and outer threads of sealed tank 2, sealed tank 1 and sealed tank 2 respectively, and then rotate them to make the sealing plug and the sealing column fit tightly with sealed tank 1 and sealed tank 2, so that the chemical substances can be stored in double layers and doubly protected at the same time, avoiding the leakage of chemical substances.

[0014] 2. By rotating the driving disk, the driving disk drives the driving rod, so that the gears are in operation. The gears drive the two rack plates to move in the slide groove, so that the rack plates correspond to the holes on the inner wall of the sealed tank one, thereby avoiding the loosening of the internal and external threads caused by the long-term storage of the sealed tank one and the sealed tank two.

[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-3 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] like Figure 1-3 As shown: This embodiment provides a sealed storage tank, including a sealed tank 100, a sealed tank 101 is arranged inside the sealed tank 100, and the sealed tank 101 is fixed inside the sealed tank 100 to ensure that the stored items are not polluted or leaked from the outside under the protection of the two-layer sealing structure. The internal ports of the sealed tank 100 and the sealed tank 101 are both provided with internal threads 103, and the upper surfaces of the sealed tank 100 and the sealed tank 101 are both provided with sealing mechanisms 200, and the sealing mechanisms 200 include sealing plugs 207 and sealing columns 208, and the sealing columns 20 A sealing plug 207 is provided at the bottom of the container 8, and a sealing column 208 fixes the sealing plug 207. The sealing plug 207 and the sealing column 208 are provided with external threads 206. The sealing column 208 can be driven by rotating the sealing plug 207, so that the sealing column 208 and the sealing plug 207 are in a state of being fitted with the sealing tank 1 100 and the sealing tank 2 101. The sealing plug 207 and the sealing column 208 are threadedly connected with the internal thread 103 through the external thread 206.
