The second fixed buckle position 202 is a first protruding tongue arranged on the inner side of the second mounting surface 201, and the first protruding tongue is suitable for rotating along the rotation groove 104.

[0064] In this embodiment, when connecting the first cover body 1 and the second cover body 2, the second cover body 2 is first buckled on the first cover body 1, and then the first cover body 1 or the second cover body 2 is rotated so that the first protruding tongue enters the rotating groove 104. The rotating groove 104 can limit the first protruding tongue in the up and down directions to prevent the second cover body 2 from falling off the first cover body 1.

[0065] In one embodiment, a positioning groove 103 is formed between the first fixing buckle 102 and the first mounting surface 101 , and the first protruding tongue is adapted to be embedded in the positioning groove 103 and rotate along the rotating groove 104 .

[0066] In this embodiment, when connecting the first cover body 1 and the second cover body 2, the second cover body 2 is first buckled on the first cover body 1 so that the first protruding tongue is embedded in the positioning groove 103, and then the first cover body 1 or the second cover body 2 is rotated so that the first protruding tongue enters the rotating groove 104, and the positioning groove 103 can be quickly positioned.

[0067] In one embodiment, Figure 5 As shown, the first fixed buckle 102 includes a first connection part 1021, a second connection part 1022, a third connection part 1023 and a fourth connection part 1024. The first connection part 1021 is protruded on the first mounting surface 101, the second connection part 1022 is connected to an end of the first connection part 1021 away from the first mounting surface 101 and extends circumferentially, a rotation groove 104 is formed between the second connection part 1022 and the first mounting surface 101, the third connection part 1023 is connected to a side of the second connection part 1022 close to the center of the first mounting surface 101 and extends circumferentially, the fourth connection part 1024 connects the first mounting surface 101 and the third connection part 1023, and the second connection part 1022, the third connection part 1023 and the fourth connection part 1024 form a positioning groove 103.

[0068] In this embodiment, when connecting the first cover body 1 and the second cover body 2, the second cover body 2 is first buckled on the first cover body 1 so that the first protruding tongue is embedded in the positioning groove 103 surrounded by the second connecting part 1022, the third connecting part 1023 and the fourth connecting part 1024. Then, the first cover body 1 or the second cover body 2 is rotated so that the first protruding tongue enters the rotating groove 104 between the second connecting part 1022 and the first mounting surface 101. The second connecting part 1022 and the first mounting surface 101 cooperate to limit the first protruding tongue in the up and down directions to prevent the second cover body 2 from falling from the first cover body 1.

[0069] In one embodiment, the first connection structure also includes a first connection buckle position 105, and the second connection structure also includes a second connection buckle position 203. The first protruding tongue is located behind the rotating groove 104, and the second connection buckle position 203 cooperates with the first connection buckle position 105 to prevent the first protruding tongue from rotating toward the positioning groove 103.

[0070] In this embodiment, when connecting the first cover body 1 and the second cover body 2, first buckle the second cover body 2 onto the first cover body 1, so that the first tongue is embedded in the positioning groove 103, and then rotate the first cover body 1 or the second cover body 2 so that the first tongue enters the rotation groove 104. The rotation groove 104 can limit the first tongue in the up and down directions to prevent the second cover body 2 from falling off the first cover body 1. At the same time, the second connection buckle position 203 cooperates with the first connection buckle position 105 to prevent the first tongue from rotating in the direction of the positioning groove 103, so as to prevent the first tongue from leaving the rotation groove 104. Therefore, the cooperation between the first fixing buckle position 102 and the second fixing buckle position 202, and the cooperation between the first connection buckle position 105 and the second connection buckle position 203 can realize the fixing of the connection between the first cover body 1 and the second cover body 2 in the circumferential direction and the up and down direction, so as to prevent loosening during use.

[0071] In one embodiment, Figure 6 , Figure 7 and Fig.16 The first connection buckle position 105 is an elastic hook, and the second connection buckle position 203 is a second protruding tongue arranged on the inner side of the second mounting surface 201. The first protruding tongue is located behind the rotating groove 104, and the elastic hook hooks the second protruding tongue.

[0072] In this embodiment, when connecting the first cover body 1 and the second cover body 2, first buckle the second cover body 2 onto the first cover body 1, so that the first tongue is embedded in the positioning groove 103, and then rotate the first cover body 1 or the second cover body 2 so that the first tongue enters the rotation groove 104. The rotation groove 104 can limit the first tongue in the up and down directions to prevent the second cover body 2 from falling off the first cover body 1. At the same time, the elastic hook hooks the second tongue to prevent the first tongue from rotating toward the positioning groove 103, so as to prevent the first tongue from leaving the rotation groove 104. Therefore, the cooperation between the first fixing buckle position 102 and the second fixing buckle position 202, and the cooperation between the first connecting buckle position 105 and the second connecting buckle position 203 can realize the fixing of the connection between the first cover body 1 and the second cover body 2 in the circumferential direction and the up and down direction, so as to prevent loosening during use.

[0073] In one embodiment, the first connecting buckle 105 includes a fifth connecting portion 1051, a sixth connecting portion 1052 and a seventh connecting portion 1053. The fifth connecting portion 1051 is protrudingly arranged on the first mounting surface 101, the sixth connecting portion 1052 is connected to the top of the fifth connecting portion 1051 and extends toward one side of the fifth connecting portion 1051, the seventh connecting portion 1053 is connected to an end of the sixth connecting portion 1052 away from the fifth connecting portion 1051 and extends toward the first mounting surface 101, the seventh connecting portion 1053 has a gap with the first mounting surface 101, the first protrusion is located behind the rotating groove 104, and the seventh connecting portion 1053 hooks the second protrusion.

[0074] In this embodiment, when connecting the first cover body 1 and the second cover body 2, the second cover body 2 is first buckled on the first cover body 1 so that the first tongue is embedded in the positioning groove 103, and then the first cover body 1 or the second cover body 2 is rotated to make the first tongue enter the rotation groove 104. The rotation groove 104 can limit the up and down directions of the first tongue to prevent the second cover body 2 from falling from the first cover body 1. At the same time, the seventh connecting portion 1053 is elastically deformed in the direction away from the first mounting surface 101 so that the second tongue passes over the seventh connecting portion 1053. After passing over the seventh connecting portion 1053, the seventh connecting portion 1053 returns to its original position to hook the second tongue, preventing the first tongue from rotating toward the positioning groove 103, thereby preventing the first tongue from leaving the rotation groove 104.

[0075] Specifically in one embodiment, Figure 4 As shown, along the circumferential direction, the first connecting buckle position 105 is located between the two first fixing buckle positions 102 , and the sixth connecting portion 1052 of the first connecting buckle position 105 extends toward the first connecting portion 1021 of one of the first connecting buckle positions 105 .

[0076] In one embodiment, a guiding inclined surface 10531 is disposed at one end of the seventh connecting portion 1053 facing the first mounting surface 101 .

[0077] In this embodiment, a guiding bevel 10531 is provided at one end of the seventh connecting portion 1053 facing the first mounting surface 101. When the second cover body 2 is rotated, when the second protruding tongue contacts the guiding bevel 10531, it will slide relative to the guiding bevel 10531, causing the seventh connecting portion 1053 to undergo elastic deformation. After the second protruding tongue passes over the seventh connecting portion 1053, the seventh connecting portion 1053 returns to its original position and hooks the second protruding tongue, thereby preventing the first protruding tongue from rotating toward the positioning groove 103.

[0078] In one embodiment, Fig.16 As shown, one side of the seventh connection portion 1053 facing the fifth connection portion 1051 is a rotation-stopping surface 10532, the angle between the vertical plane 3 perpendicular to the first mounting surface 101 and the rotation-stopping surface 10532 is α, and the friction coefficient between the second protrusion and the rotation-stopping surface 10532 is μ, μ>tanα.

[0079] In this embodiment, the angle between the vertical plane 3 perpendicular to the first mounting surface 101 and the anti-rotation surface 10532 is α, the friction coefficient between the second protruding tongue and the anti-rotation surface 10532 is μ, μ>tanα, and when the second cover body 2 is subjected to a rotational force, the second protruding tongue cannot separate from the elastic hook.

[0080] Specifically, assuming that the gyroscopic force is F, the positive pressure of the second tongue on the anti-rotation surface 10532 is N, the resultant force of F and N is F1, F1 = N*tanα, the friction resistance between the second tongue and the anti-rotation surface 10532 is f, and the friction coefficient is μ. To ensure that it cannot be dislodged, it is necessary to satisfy f>F1, then N*μ>N*tanα, so the result is μ>tanα.

[0081] In one embodiment, the second cover body 2 is sealed to the first cover body 1 via a first sealing member 4 .

[0082] In this embodiment, the second cover body 2 and the first cover body 1 are sealed and connected via the first sealing member 4 , so as to prevent water or foreign matter from entering the space between the first cover body 1 and the second cover body 2 .

[0083] Specifically in one embodiment, the first cover body 1 is provided with a mounting groove 108 , and the first sealing member 4 is disposed in the mounting groove 108 .

[0084] In this embodiment, by providing a mounting groove 108 on the first cover body 1 , the positioning and mounting of the first sealing member 4 is facilitated.

[0085] Specifically, the first sealing member 4 is disposed in the mounting groove 108 and a portion thereof is exposed. After the first cover body 1 and the second cover body 2 are assembled, the first sealing member 4 abuts against the second cover body 2 .

[0086] The first sealing member 4 is specifically an O-ring.

[0087] In one embodiment, the second cover body 2 has a working surface 207 and a flange 208 . The flange 208 is folded inward from the edge of the working surface 207 on the back side of the working surface 207 to form a second mounting surface 201 . The flange 208 abuts against the first sealing member 4 .

[0088] Beneficial effect: The flange 208 is folded inward from the edge of the working surface 207 on the back side of the working surface 207 to form the second mounting surface 201.
