DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example

[0039] See Figures 1 to 6 As shown, a new storage tank structure includes a tank body 1 and a tank cover structure 2 arranged at the bottle mouth of the tank body. In this embodiment, the tank body can be a plastic tank body or a glass tank body, and the tank cover structure includes an outer cover 21, an inner cover 22, an inner cover handle 23 and an outer cover handle 24; the outer cover, inner cover, inner cover handle and outer cover handle are all plastic structures.

[0040] In actual use, the outer cover has an outer protrusion 3 integrally formed on the lower symmetrical outer wall, and an inner protrusion 4 integrally formed on the upper symmetrical inner wall; the inner protrusion is elliptical. Protrusions 5 are provided at both ends of the inner cover. During assembly and use, the outer cover handles are rotatably connected to the outer protrusions. The outer cover handles are primarily used for lifting the entire structure, thereby improving its ease of use.

[0041] At the same time, an axis hole 6 is provided at both ends of the inner cover handle, and a U-shaped protrusion 7 is integrally formed on the outer wall of both ends of the inner cover handle, and the opening of the U-shaped protrusion is at the end edge of the inner cover handle; during assembly, the convex axis body can be rotatably connected in the axis hole, and the inner axis protrusion is in the concave area of the U-shaped protrusion in a vertical state; when the inner cover handle is folded on the top surface of the inner cover, the inner axis protrusion is in the horizontal U-shaped protrusion to connect and position the inner cover and the outer cover. The U-shaped handle can be easily removed from the cover by sliding it downwards, and the inner cover can be easily opened by sliding it downwards, thereby preventing the inner cover from becoming loose or detached.

[0042] In actual use, the top surface of the inner lid is provided with a semicircular groove 8, and the ends of the semicircular groove are provided with through holes 9 that are transparent from top to bottom. The protruding shaft body is located in the through holes at both ends of the semicircular groove, and the protruding shaft body is located on the side of the semicircular groove near the center. This structure allows the inner lid handle to be locked into the semicircular groove when folded, thereby ensuring the stable connection between the inner shaft protrusion and the U-shaped protrusion, and ensuring the reliability of the connection between the inner lid and the outer lid.

[0043] In actual use, an inner cover buckle protrusion 10 is fixed to the outer wall of the semicircular groove; a buckle groove 11 is fixed to the outer wall of the inner cover handle. During assembly, the inner cover buckle protrusion snaps into the buckle groove to retain its position. To enhance operational convenience, an operating tab 12 is fixed to the inner cover handle; the buckle groove is located directly below the operating tab. This structure ensures that the inner cover handle is locked into the semicircular groove and will not loosen or fall off without external force. In other words, the U-shaped protrusion maintains a stable horizontal position, thus ensuring a reliable connection between the inner and outer covers.

[0044] In actual application, the lower portion of the inner wall of the outer cover is provided with inner teeth 13; the outer wall of the opening of the tank body is provided with outer teeth 14; the outer cover and the tank body are fixed together by the inner and outer teeth, which improves the convenience, stability and reliability of the connection between the two.

[0045] In actual use, the inner lid is provided with a sealing ring groove 15 on its outer annular surface; a sealing ring 16 is fixed in the sealing ring groove, and the inner lid is sealed against the inner wall of the bottle mouth via the sealing ring. This structure can improve the sealing state of the items in the storage tank, prevent the items from getting damp and deteriorating, and prevent foreign matter from entering the storage tank, which also helps to extend the storage time of the items.

[0046] In actual application, the side of the outer convex shaft is fixed with a limiting convex point 17; the outer cover handle is turned over and limited by the limiting convex point. The limiting convex point can ensure that the outer cover handle is in a stable position when folded.

[0047] Its installation method:

[0048] The first step is to install the outer cover on the bottle mouth of the tank and tighten it;

[0049] Step 2: Install the outer cover handles on both sides of the outer cover on the outer convex shafts on both sides of the outer cover.

[0050] The third step is to install the convex shafts on both sides of the inner cover into the shaft holes on the inner side of the inner cover handle.

[0051] Step 4: Put the sealing ring into the sealing ring groove at the bottom of the inner cover;

[0052] Step 5: Flip the inner cover handle so that the U-shaped raised opening on the outside faces downward and fits over the elliptical shaft on the inside of the outer cover.

[0053] Step 6: Lay the inner cover handle flat so that the inner cover is fixed in the middle of the outer cover to complete the installation.

[0054] When the inner cover needs to be removed from the outer cover, the inner cover handle is turned vertically. At this time, the opening of the U-shaped protrusion is directly below, and when the inner cover is lifted up, the inner cover protrusion is disengaged from the U-shaped protrusion to achieve the detachment operation, which makes the inner cover more convenient to open and close, and can also ensure the stability and reliability of use. It will not cause the inner cover and the outer cover to stick together, thus avoiding the technical problem of the lid being difficult to open. It has strong applicability and practicality.

[0055] In addition, a sealing ring is provided between the outer cover and the inner wall of the bottle mouth, thereby ensuring the sealing of the connection and effectively improving the sealing and moisture-proof performance.

[0056] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0057] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
