DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Example 1

[0032] Reference Figures 1 - 5 A tank device comprises: an outer tank 1 and an inner tank 10, wherein the inner tank 10 is arranged in the outer tank 1, a connecting cover 2 for fixing the inner tank 10 is clamped on the top of the outer tank 1 through a clamping piece, an inner cover 8 for sealing the inner tank 10 is arranged in the connecting cover 2, a top cover 4 is arranged on the inner thread of the connecting cover 2 for limiting the position of the inner cover 8, and the top cover 4 cooperates with the clamping piece to fix the clamping piece;

[0033] Two sliding rods 19, the two sliding rods 19 are symmetrically arranged on the top cover 4, and the sliding rods 19 can be retracted into the top cover 4 for hiding when not in use, and can be extended to apply pressure and rotation force to the top cover 4;

[0034] The reset assembly is arranged in the outer tank 1, and is used to automatically drive the inner tank 10 to move upward in the outer tank 1 when the clamping piece is opened. The inner tank 10 can be fixed between the outer tank 1 and the connecting cover 2 through the setting of the clamping piece, and by twisting the top cover 4, not only the inner cover 8 can be limited, but also the clamping piece can be fixed, so that it is convenient to open and close. At the same time, after opening, the inner tank 10 can be automatically driven to move upward through the reset assembly, making it more convenient to take and put the inner tank 10.

[0035] The reset assembly includes a sliding plate 13 slidably arranged on the inner wall of the outer tank 1, and a first spring 14 is arranged in the outer tank 1. The two ends of the first spring 14 are respectively fixedly connected to the bottom of the sliding plate 13 and the bottom wall of the outer tank 1, so as to provide a reset power for the sliding plate 13. When the connecting cover 2 is clamped on the outer tank 1, the inner tank 10 can be driven to move downward through the connecting cover 2. The downward movement of the inner tank 10 can resist the downward movement of the sliding plate 13 and compress the first spring 14. Conversely, when the connecting cover 2 is removed from the outer tank 1, the sliding plate 13 can be reset upward under the action of the first spring 14, thereby driving the inner tank 10 to move upward, so that the top end of the inner tank 10 extends out of the outer tank 1 for easy removal.

[0036] The clamping parts include two clamps 3, the two clamps 3 are rotatably connected at one side close to each other, and the other sides are connected to the top cover 4. The outer edges of the outer tank 1 and the connecting cover 2 are provided with a tapered portion 9, and the two clamps 3 are completely in contact with the tapered portion 9 after being closed. Through the setting of the two clamps 3 and the tapered portion 9, the outer tank 1 and the connecting cover 2 can be fixed. At the same time, the setting of the tapered portion 9 can increase the contact area with the clamps 3, and can also slowly fit from loose to tight, which can improve the sealing performance.

[0037] A first rotating ring 5 is rotatably provided on the outer wall of the top cover 4, a second rotating ring 6 is rotatably provided on the outer wall of the first rotating ring 5, an insertion rod 7 is fixedly provided on the bottom of the second rotating ring 6, a yielding portion 16 is provided on the top and bottom of one of the clamps 3, an extension portion 15 corresponding to the yielding portion 16 is fixedly provided on one side of the other clamp 3, corresponding insertion holes 17 are provided on the extension portion 15 and the yielding portion 16, the insertion rod 7 is located in the two groups of insertion holes 17, and the two clamps 3 can be fixed by inserting the insertion rod 7 into the two groups of insertion holes 17. During use, the two clamps 3 will not rotate, making the clamping convenient and more secure.

[0038] Two symmetrically arranged mounting grooves 18 are provided on the outer wall of the top cover 4. A sliding rod 19 is slidably arranged in the mounting groove 18. A second spring 20 is arranged in the mounting groove 18. The two ends of the second spring 20 are respectively fixedly connected to the inner side of the mounting groove 18 and one end of the sliding rod 19. A through hole 21 for cooperating with the sliding rod 19 is provided on the outer wall of the first rotating ring 5. By rotating the first rotating ring 5, the position of the through hole 21 can be adjusted. When the through hole 21 corresponds to the mounting groove 18, the sliding rod 19 can automatically pop out under the action of the second spring 20. When the sliding rod 19 is not needed, the sliding rod 19 is pressed inward to compress the second spring 20 until one end of the sliding rod 19 is flush with the inner wall of the first rotating ring 5. At this time, the first rotating ring 5 can rotate to adjust the movement of the through hole 21 so that the through hole 21 is misaligned with the mounting groove 18, and the sliding rod 19 can be stored and hidden.

[0039] A sealing ring (not marked in the figure) is provided between the outer tank 1 and the connecting cover 2. By providing a sealing ring between the outer tank 1 and the connecting cover 2, the outer tank 1 and the connecting cover 2 can have elasticity and no leakage will occur at the same time.

[0040] A flange 11 is provided at the top end of the inner tank 10. A positioning groove 12 for cooperating with the flange 11 is provided at the top of the outer tank 1 for positioning the inner tank 10. Through the cooperation of the flange 11 and the positioning groove 12, the inner tank 10 can be positioned, and after the connecting cover 2 and the outer tank 1 are engaged, the inner tank 10 will not move up and down, avoiding a gap between the inner tank 10 and the inner cover 8 and causing leakage.

[0041] This application can be used for strong acid digestion and can also be used in other fields applicable to this application.
