[0005] Preferably, a step is provided on the inner ring, and the sealing ring is located on the step.

[0006] Preferably, a thread segment a is provided on the outer side wall of the inner ring, and a thread segment b corresponding to the thread segment a is provided on the inner side wall of the outer ring.

[0007] Preferably, the inner ring and the outer ring are both mounted on the outer side wall of the water pipe, and the water pipe passes through the through hole on the water tank.

[0008] The utility model has the following advantages: the utility model makes the outer ring and the inner ring threadedly connected, and makes the sealing ring located in the through hole of the water tank, thereby preventing the sealing ring from falling from the through hole; at the same time, because the sealing ring is located in the through hole, deformation of the sealing ring during long-term use, which leads to reduced sealing of the water tank, is avoided.

[0013] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0014] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0015] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0016] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0017] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, or the positions or positional relationships commonly understood by those skilled in the art, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] In this embodiment, if Figure 1~Figure 3As shown, a sealing device for the inlet and outlet of a water tank water pipe comprises an inner ring 3 and an outer ring 4, a sealing ring 5 is arranged on the outer side of the inner ring 3, the outer side of the inner ring 3 is threadedly connected to the inner side of the outer ring 4, and the end of the outer ring 4 abuts against the sealing ring 5, and the sealing ring 5 is located in the through hole of the water tank 1. By threading the outer ring 4 with the inner ring 3 and locating the sealing ring 5 in the through hole of the water tank 1, the sealing ring 5 can be prevented from falling from the through hole. At the same time, since the sealing ring 5 is located in the through hole, the deformation of the sealing ring 5 during long-term use can be avoided, which causes the sealing performance of the water tank 1 to be reduced. In this embodiment, the inner ring 3 and the outer ring 4 are both made of steel.

[0020] Furthermore, a step 6 is provided on the inner ring 3, and the sealing ring 5 is located on the step 6. Furthermore, a threaded section a is provided on the outer wall of the inner ring 3, and a threaded section b corresponding to the threaded section a is provided on the inner wall of the outer ring 4. In this embodiment, the inner ring 3 and the outer ring 4 are both installed on the outer wall of the water pipe 2, and the water pipe 2 passes through the through hole on the water tank 1. Specifically, the staff first installs the inner ring 3 and the outer ring 4 on the water pipe 2, and makes the inner ring 3 inside the water tank 1 and the outer ring 4 outside the water tank 1, and then places the sealing ring 5 on the step 6, pushes part of the inner ring 3 into the through hole, so that the sealing ring 5 is located in the through hole, and finally pushes part of the outer ring 4 into the through hole, so that the threaded section b and the threaded section a cooperate with each other, so that the outer ring 4 is threadedly connected with the inner ring 3, thereby fixing the sealing ring 5 in the through hole to prevent the sealing ring 5 from falling from the through hole. At the same time, since the sealing ring 5 is located in the through hole, the sealing ring 5 is prevented from being deformed during long-term use, which causes the sealing performance of the water tank 1 to be reduced. In this embodiment, the through hole is an inlet or an outlet.

[0021] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
