[0027] Embodiment: Refer to Figure 1-9A leak-proof storage device for magnetic fluid shown in the figure includes a tank body 1 with a tank opening on its top surface. On the top surface of the tank opening, there are four groups of grooves 11 arranged in an annular array. The inner wall of each group of grooves 11 is provided with a T-shaped limiting block 12. A limiting member 4 provided at the bottom of the cover 2 is inserted into the groove 11. By rotating the rotating block 3 provided on the cover 2, the driving mechanism is driven to rotate, thereby driving the connected limiting member 4 to rotate, realizing the cooperation between the limiting member 4 and the limiting block 12, completing the sealing of the cover 2 on the tank opening, and completing the sealing of the magnetic fluid inside the tank body 1.

[0028] The cover 2 includes a bottom cover 21 with a groove on its top surface and a cover plate 24. The two cooperate to limit and protect the driving mechanism arranged in the groove. The rotating block 3 rotatably connected to the cover plate 24 passes through the rotating hole 25 of the cover plate 24 and is connected to the driving mechanism. Through the positioning bolt 32 threadedly connected to the T-shaped rotating block 3, the positioning bolt 32 rotates and lifts in the adjusting hole 31 and is inserted into the positioning groove 26. After rotation, the angle is fixed to prevent the cover 2 from falling off.

[0029] Driving mechanism: There are six groups of positioning heads 23 arranged in an annular array in the groove. The purpose is to limit the annular gear 6. The bottom surface of the annular gear 6 is provided with an annular groove, and the position between the annular groove and the positioning heads 23 corresponds to each other to achieve the purpose of limiting the annular gear 6. Both the inner wall and the outer wall of the annular gear 6 are provided with teeth. A transfer gear 7 is rotatably connected to the inner ring (on the groove) of the annular gear 6, and a driving gear 8 is rotatably connected to the middle of the groove. The driving gear 8 is meshed with the annular gear 6 through the transfer gear 7. A driven gear 5 meshed with the outer wall of the annular gear 6 is provided. The above-mentioned rotating block 3 is coaxially arranged with the driving gear 8, so as to realize driving the driving mechanism to rotate by rotating the rotating block 3.

[0030] The top surface of the limiting member 4 is provided with a connecting rod 43. The top of the connecting rod 43 is hexagonal, and the connecting rod 43 is rotatably connected in the through hole 22 of the bottom cover 21. The middle part of the driven gear 5 is provided with a connecting hole 51, and the bottom of the connecting hole 51 is hexagonal and is adapted to the top of the connecting rod 43, so as to realize the first-step installation of the limiting member 4 and the driven gear 5. Subsequently, the driven gear 5 and the connecting rod 43 are installed through bolts. Through the above structure, the annular gear 6 and the driven gear 5 are meshed to drive the limiting member 4 to rotate.

[0031] An L-shaped limiting groove 42 is provided on the inner wall of the slot 41. The limiting block 12 moves in the horizontal section of the limiting groove 42, so as to realize angle fixation and complete the installation of the cover 2.

[0032] Working principle of this utility model: By aligning the limiting member 4 at the bottom of the cover 2 with the groove 11 on the can mouth, the slot 41 at the bottom of the limiting member 4 is fitted with the limiting groove 42, and the docking with the limiting block 12 is completed. Subsequently, by rotating the rotating block 3, the rotating block 3 rotates in the rotating hole 25 of the cover plate 24, driving the driving gear 8 coaxially arranged with it to rotate in the groove of the bottom cover 21. Thus, the ring gear 6 is driven to rotate by the transfer gear 7 meshing with it. The ring gear 6 is fitted with the positioning head 23 through the annular groove on the bottom surface to achieve positioning rotation, thereby driving the driven gear 5 to rotate. The driven gear 5 is fitted with the connecting rod 43 through the connecting hole 51 (the two are connected by bolts), thereby driving the limiting member 4 to rotate, and the limiting block 12 rotates in the limiting groove 42, thus completing the limiting and achieving the purpose of storing the magnetic fluid inside the tank body 1. And through the above structure, leakage of materials is avoided (compared with the existing cover methods such as screw rotation, this design scheme only needs to rotate a small angle to complete the cover. Subsequently, rotate the positioning bolt 32, so that the positioning bolt 32 rises and falls in the adjustment hole 31 and inserts into the positioning groove 26 to complete the positioning).
