[0046] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the scope of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0047] As shown in Fig. 3-9 , the embodiment of the present application provides a locking structure, comprising:

[0048] an interface rigid pipe assembly 21, comprising a fixing plate 211 and a rigid pipe 212, the rigid pipe 212 being fixedly connected to the fixing plate 211 and penetrating through the fixing plate 211;

[0049] a rotating locking assembly 22, located outside the rigid pipe 212 and rotatably connected to the fixing plate 211 so as to be able to rotate around the rigid pipe 212, the rotating locking assembly 22 comprising a rotating pipe 221 and a locking piece 222 located on the inner wall of the front end of the rotating pipe 221 and capable of penetrating through the notch 111 and entering the ring cutting groove 112; the locking piece 222 is a roller rotatably connected to the inner wall of the rigid pipe 212, and the number of the locking pieces 222 is the same as the number of the notches on the tank opening, and the positions are opposite;

[0050] The plug sealing assembly 23 is located between the rigid pipe 212 and the rotating pipe 221, and is directly or indirectly connected to the fixed plate 211. The plug sealing assembly 23 comprises a plug 231, and the distance from the plug 231 to the center of the rigid pipe 212 in the radial direction is equal to the distance from the locking member 222 to the upper surface of the tank mouth 11 in the radial direction, and the distance in the axial direction is less than the distance from the annular groove 112 to the upper surface of the tank mouth 11.

[0051] The plug sealing assembly 23 further comprises a sealing member 232, and the plug 231 is connected to the outer side of the front end of the sealing member 232, so that the sealing member 232 can be sealingly connected to the inner wall of the tank mouth 11.

[0052] The outer side of the sealing member 232 is provided with a first sealing ring 2321, so as to be sealingly connected to the rim or the inner wall of the tank mouth 11. The first sealing ring 2321 can form a sealing connection between the sealing member 232 and the inner wall of the tank mouth 11.

[0053] The inner side of the sealing member 232 is further provided with a second sealing ring 2322, so as to be sealingly connected to the outer wall of the rigid pipe. The second sealing ring 2322 can form a sealing connection between the sealing member 232 and the rigid pipe 212.
