[0024] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0025] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] Please refer to Figure 1 and Figure 2 As shown, the utility model provides a sealing ring 101, which includes: an annular base 1 and a plurality of positioning and mounting modules 2.

[0027] The annular base 1 has a first thickness in a first direction X, and includes two end surfaces perpendicular to the first direction X.

[0028] A plurality of positioning and mounting modules 2 are sequentially distributed on the end surface of the annular base 1 along the annular direction of the annular base 1, and each positioning and mounting module 2 includes a mounting blind hole 21 and a positioning protrusion 22. The mounting blind hole 21 is opened on one end surface of the annular base 1 along the first direction X, and the positioning protrusion 22 is protrudingly arranged on the other end surface of the annular base 1 along the first direction X, and the mounting blind hole 21 is arranged directly above the positioning protrusion 22. The directly arranged arrangement in this article refers to the coincidence of the center lines of the two related elements in the first direction X. The projection of the mounting blind hole 21 on the end surface of the annular base 1 covers the projection of the positioning protrusion 22 on the end surface of the annular base 1, wherein the distance between the bottom of the mounting blind hole 21 and the other end surface of the annular base 1 is one tenth to one fifth of the first thickness. That is, the connection thickness of the positioning protrusion 22 in the first direction X of the annular base 1 is one tenth to one fifth of the thickness of the annular base 1. Such a connection thickness can not only ensure the connection strength between the positioning protrusion and the annular base, but also effectively ensure that the positioning protrusion can be pushed off the annular base when the mounting screw is rotated.

[0029] Optionally, a plurality of positioning and mounting modules 2 are uniformly distributed on the end surface of the annular base 1 in sequence along the annular direction of the annular base 1. Such a configuration makes the sealing ring more stable when installed on the flange of the liquid storage tank body, and is more convenient for selecting the installation position of the liquid storage tank cover body as needed.

[0030] Optionally, the inner and outer contours of the annular base 1 are both rectangular with arc transitions. Such a shape is more suitable for matching the shape of a conventional liquid storage tank. Of course, the inner and outer contours of the annular base are not limited to this, and can also be other closed ring shapes such as circles, rectangles, triangles, etc., which are specifically determined according to the shape of the liquid storage tank.

[0031] Optionally, the positioning protrusion 22 is a cylinder, the mounting blind hole 21 is a round hole, and the inner diameter of the mounting blind hole 21 is not less than the outer diameter of the positioning protrusion 22. This arrangement facilitates the positioning protrusion to fall off better when the screw is installed.

[0032] Optionally, the spacing between the positioning protrusion 22 and the inner and outer rings of the annular base 1 is the same. In this way, arranging the positioning protrusion in the middle position can achieve better sealing and fixing effects.

[0033] Optionally, the protrusion height of the positioning protrusion 22 along the first direction X is one to two times the first thickness. This arrangement facilitates the sealing ring to be fixed on the flange of the box body.

[0034] Optionally, a chamfer 221 is provided on one end of the positioning protrusion 22 away from the mounting blind hole 21. This arrangement facilitates the guiding and positioning of the sealing ring during installation.

[0035] The sealing ring of the utility model has a compact structure and an ingenious design, and can conveniently and reliably realize the sealing and covering between the cover body and the box body.

[0036] Please refer to Figure 3 and Figure 4 As shown, the utility model further provides a lower box 102, comprising a box body 3, a plurality of fixing modules 4 and the sealing ring 101 as described above.

[0037] A flange 31 perpendicular to the first direction is formed around the top of the box body 3 .

[0038] A plurality of fixing modules 4 are sequentially distributed on the flange 31 . Each fixing module 4 includes a fixing through hole 41 and a fixing nut 42 . The fixing through hole 41 is provided on the flange 31 , and the fixing nut 42 is arranged directly below the fixing through hole 41 .

[0039] The sealing ring 101 is buckled on the flange 31, wherein the multiple positioning protrusions 22 on the sealing ring 101 correspond to the multiple fixing modules 4 one by one, and each positioning protrusion 22 passes through the corresponding fixing through hole 41 and is inserted and fixed in the threaded hole of the corresponding fixing nut 42. Such a setting of the sealing ring is more convenient when installing and replacing it on the box body, and the cover body has a better sealing effect after installation.

[0040] Optionally, each positioning protrusion 22 passes through the corresponding fixing through hole 41 and is tightly inserted into the threaded hole of the corresponding fixing nut 42. That is, the size of the positioning protrusion is set to be slightly larger than the threaded hole of the fixing nut, so that the sealing ring is better fixed on the flange.

[0041] The lower box body of the utility model can be set as a universal standard part, which is convenient for matching with the non-standard parts of the cover body set as required to meet different needs.

[0042] Please refer to 4 and Figure 5 As shown, the utility model also provides a liquid storage box 100, including a cover body 5 and the lower box body 102 described above, the cover body 5 is covered and fixed on the lower box body 102, and a plurality of screw holes 51 are provided on the edges around the top of the cover body 5 as required, and each screw hole 51 has a fixed through hole 41 arranged opposite to the flange 31 of the lower box body 102, wherein the number of the fixed through holes 41 on the flange 31 is greater than the number of the screw holes 51. This makes it convenient to fix the cover body and the sealing ring on the box body after the screws pass through the screw holes and the blind holes. Since the number of the fixed through holes and the positioning protrusions is greater than the number of the screw holes, the lower box body can be made into a universal standard part, and screw holes in different positions can be provided on the edges around the top of the cover body as required, so that the liquid storage tank can optimize the layout of other functional parts according to actual conditions, and the positioning protrusions at other places where no screws are installed continue to be retained, which is convenient for disassembly and positioning.

[0043] The installation method of the liquid storage tank 100 of an embodiment of the utility model is as follows:

[0044] First, snap all the multiple positioning protrusions 22 on the sealing ring 101 into the corresponding fixing through holes 41 and fixing nuts 42 on the box body 3 in turn, then cover the cover body 5 on the lower box body 102, and then install the screws in turn at the positions of the screw holes 51 opened on the cover body 5. The screws pass through the screw holes 51 and the mounting blind holes 21 in turn, push down the positioning protrusions 22, and then pass through the fixing through holes 41 and be fixed in the threaded holes of the fixing nuts 42, so that the cover body 5 is sealed on the box body 3. In addition, the liquid storage tank 100 can be turned over to check whether the screws are all installed in place, thereby confirming whether the sealing ring 101 is installed in place.

[0045] The liquid storage box of the utility model can conveniently seal the cover body and the box body without glue, and can also check whether the sealing ring is installed in place, and is convenient to disassemble.
