[0035] Example 1

[0036] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment proposes a high-sealing liquid transport tank assembly, including a tank body 1 and a liquid inlet 101 opened at one end of the top of the tank body 1, a cover plate 2 is provided on the top of the liquid inlet 101, a connecting seat 3 is provided between the side of the cover plate 2 and the tank body 1, an inner cylinder 4 is fixed at the middle position of the bottom of the cover plate 2, the outer diameter of the inner cylinder 4 is the same as the inner diameter of the liquid inlet 101, the interior of the inner cylinder 4 is provided with a fastening mechanism 5 for positioning the cover plate 2, an outer sleeve 6 is fixed to the outside of the bottom of the cover plate 2, the inner diameter of the outer sleeve 6 is larger than the outer diameter of the inner cylinder 4, and the inner bottom of the outer sleeve 6 is provided with a sealing mechanism 7 that fits tightly with the outer side of the inner cylinder 4.

[0037] During installation, the cover plate 2 is covered on the top of the liquid inlet 101, the inner cylinder 4 is inserted into the interior of the liquid inlet 101 and fits against the inner wall of the liquid inlet 101, and the outer sleeve 6 fits against the outer wall of the liquid inlet 101. The position of the inner cylinder 4 is fixed by the fastening mechanism 5. At the same time, during the fixing process, the sealing mechanism 7 is automatically controlled to make the inner wall of the outer sleeve 6 fit tightly against the outer side of the liquid inlet 101.

[0038] Example 2

[0039] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0040] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned embodiment, further, a sealing ring is provided on the outer side of the inner cylinder 4 along the circumferential direction, and the sealing rings are located on different horizontal planes and provided in three groups.

[0041] Multiple sets of sealing rings can form multi-level seals on different horizontal surfaces outside the inner cylinder 4, thereby improving the sealing effect between the inner cylinder 4 and the liquid inlet 101.

[0042] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, the connecting seat 3 further includes a vertical rod 301, a strip groove 302, an axis rod 303 and a connecting block 304, the vertical rod 301 is vertically fixed to the top of the tank body 1, and a strip groove 302 is provided between the two sides of the vertical rod 301, and the axis rod 303 is slidably installed inside the strip groove 302, and the two ends of the axis rod 303 are fixed with connecting blocks 304, and the connecting block 304 is fixed to the outer side of the cover plate 2.

[0043] During the opening and closing process of the cover plate 2 , the cover plate 2 rotates around the shaft 303 , and when the cover plate 2 is sealed and fixed, the strip groove 302 reserves space for the movement of the shaft 303 , so that the cover plate 2 can move vertically downward.

[0044] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, the fastening mechanism 5 further includes an insert block 501, an inclined guide surface 502, a turntable 503, a flat thread 504 and an adjusting rod 505. The insert blocks 501 are distributed in a circular array at the bottom end of the inner cylinder 4, and the insert blocks 501 are perpendicular to the side of the inner cylinder 4. The insert blocks 501 are slidingly connected to the inner cylinder 4. The outer ends of the insert blocks 501 are all provided with inclined guide surfaces 502. The turntable 503 is rotatably installed on the inner bottom of the inner cylinder 4. The bottom of the turntable 503 is provided with a flat thread 504. The top of the insert block 501 is engaged with the flat thread 504. The adjusting rod 505 is fixed at the middle position of the top of the turntable 503, and the adjusting rod 505 extends to the top of the cover plate 2.

[0045] During the process of fixing the device, the adjustment rod 505 is used to control the rotation of the turntable 503. The bottom of the turntable 503 engages with the top of the plug block 501 through the flat thread 504, so that the sliding out of the plug block 501 can be controlled at the same time. The inclined guide surface 502 at the end of the plug block 501 first contacts the bottom end of the liquid inlet 101. As the plug block 501 continues to move, the cover plate 2 is pressed down until the flat surface of the top of the plug block 501 is in contact with the inner top of the tank body 1, and the positioning of the cover plate 2 is completed.

[0046] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, an adjusting wheel is fixed to the top end of the adjusting rod 505, and an anti-slip protrusion is provided on the adjusting wheel.

[0047] In the process of controlling the rotation of the adjusting rod 505, the existence of the adjusting wheel can facilitate manual control and is more practical.

[0048] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a sealing ring is fixed on the outer side of the turntable 503 , and the sealing ring is in contact with the inner wall of the inner cylinder 4 .

[0049] The presence of the sealing ring outside the turntable 503 can improve the sealing performance inside the inner cylinder 4.

[0050] like Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, the sealing mechanism 7 further includes an annular piston 701, a spring 702, an annular groove 703 and an elastic membrane 704. The annular piston 701 is slidably arranged between the inner cylinder 4 and the outer sleeve 6. A spring 702 is provided between the top of the annular piston 701 and the bottom of the cover plate 2. The spring 702 is sleeved on the outside of the inner cylinder 4. An annular groove 703 is provided on the inner bottom of the outer sleeve 6. The annular groove 703 is communicated with the inner top of the outer sleeve 6. An elastic membrane 704 is provided inside the annular groove 703.

[0051] During the process of fixing the cover plate 2, the top of the liquid inlet 101 will exert an upward extrusion force on the annular piston 701, moving the annular piston 701 upward. At this time, the gas between the inner cylinder 4, the outer sleeve 6 and the annular piston 701 will be squeezed into the inside of the annular groove 703, and the elastic membrane 704 will expand and fit the outside of the liquid inlet 101, ensuring the sealing between the outer sleeve 6 and the liquid inlet 101.

[0052] Example 3

[0053] The solutions in Example 1 and Example 2 are further introduced below in conjunction with specific working methods, as described below:

[0054] During installation, the cover plate 2 is rotated around the shaft 303 and covers the top of the liquid inlet 101. The inner cylinder 4 is inserted into the interior of the liquid inlet 101 and fits with the inner wall of the liquid inlet 101, while the outer sleeve 6 fits with the outer wall of the liquid inlet 101. The rotation of the turntable 503 is controlled by the adjusting rod 505. The bottom of the turntable 503 engages with the top of the insert 501 through the flat thread 504, so that the sliding out of the insert 501 can be controlled at the same time. The inclined guide surface 502 at the end of the insert 501 first contacts the bottom end of the liquid inlet 101, and as the insert 501 continues to move, pressing the cover plate 2 downward until the plane of the top of the insert block 501 fits against the inner top of the tank body 1, and the cover plate 2 is positioned. During the downward movement of the cover plate 2, the top of the liquid inlet 101 will exert an upward extrusion force on the annular piston 701, moving the annular piston 701 upward. At this time, the gas between the inner cylinder 4, the outer sleeve 6 and the annular piston 701 will be squeezed into the inside of the annular groove 703, and the elastic membrane 704 will expand and fit against the outside of the liquid inlet 101, ensuring the sealing between the outer sleeve 6 and the liquid inlet 101.

[0055] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
