[0018] like Figures 1 to 5 As shown, the waterproof power strip of this utility model includes: a first housing 1 and a second housing 2, which are coaxially rotatable, and the second housing 2 can rotate to cover the opening of the first housing 1, so that a sealed accommodating space for accommodating the power strip 3 is formed between the first housing 1 and the second housing 2; a first sleeve 4 and a second sleeve 5, the top ends of the first housing 1 and the second housing 2 are rotatably connected through the first sleeve 4, the first sleeve 4 can lead out the first cable 31 of the power strip 3 in the accommodating space, the bottom ends of the first housing 1 and the second housing 2 are rotatably connected through the second sleeve 5, the second sleeve 5 can lead out the second cable plugged into the socket of the power strip 3; wherein, the side of the second sleeve 5 is provided with a through notch 51 to facilitate the entry or exit of the second cable into the second sleeve 5.

[0019] See Figures 1 to 5 The first housing 1 and the second housing 2 have a "D" shaped cross-section perpendicular to their respective length directions. Both the first housing 1 and the second housing 2 have recessed spaces to accommodate the power strip 3. The second housing 2 is proportionally smaller than the first housing 1, so that when the second housing 2 is placed inside the first housing 1, the top of the second housing 2 abuts against the inner top surface of the first housing 1, and the bottom of the second housing 2 abuts against the inner bottom surface of the first housing 1. In addition, the first housing 1 and the second housing 2 are configured to rotate about the same axis. The second housing 2 has a first side 21 and a second side 22. The first side 21 is the side of the second housing 2 that rotates clockwise to cover the opening of the first housing 1, and the second side 22 is the side of the second housing 2 that is always placed inside the first housing 1.

[0020] See Figures 2 to 5Both the first housing 1 and the second housing 2 have a through hole in the middle of their top surfaces. A first sleeve 4 is located in the first hole and is shaped like an "I" to limit the movement of the first housing 1 and the second housing 2. A power strip 3 is connected to the power supply via a first cable 31. The power strip 3 is placed in the accommodating space formed by the first housing 1 and the second housing 2. The first cable 31 passes through the first sleeve 4. Both the first housing 1 and the second housing 2 have a through hole in the middle of their bottom surfaces. An "I" shaped second sleeve 5 is located in the second hole to further limit the rotation of the first housing 1 and the second housing 2. A second cable is plugged into the socket of the power strip 3 via a connector. The other end of the second cable is used to connect to the device to be powered on. It should be noted that the second sleeve 5 has a notch 51 that passes through both ends of it. This notch 51 is used for the first cable 31 to enter or exit the second sleeve 5.

[0021] When using the waterproof power strip 3 of this application, firstly, the second cable is placed inside the second sleeve 5 through the notch 51 of the second sleeve 5, and then the plug connected to the second cable is inserted into the socket of the power strip 3. After that, the second housing 2 is rotated clockwise so that the second housing 2 gradually rotates out from the first housing 1 and covers the opening of the first housing 1, thereby covering the power strip 3 placed in the accommodating space and reducing the possibility of short circuit of the power strip 3 caused by water vapor entering the accommodating space.

[0022] In one or more embodiments, a bent groove plate 6 is installed on the inner wall of the first housing 1 along its length direction. A limiting groove 61 is formed between the bent groove plate 6 and the first housing 1. The second housing 2 is rotated to cover the opening of the first housing 1, so that the first side 21 of the second housing 2 can enter the limiting groove 61 and be stopped and limited by the groove plate 6.

[0023] See Figures 2 to 5 The two ends of the groove plate 6 do not abut against the inner top surface and the inner bottom surface of the first housing 1. The length of the groove plate 6 is configured to be equal to the length of the first side 21 of the second housing 2. This arrangement allows the limiting groove 61 formed between the groove plate 6 and the first housing 1 to completely cover the first side 21 of the second housing 2, thereby further improving the sealing effect on the accommodating space. In addition, a rubber pad can be provided on the surface of the limiting groove 61 to further improve the sealing performance of the connection between the first housing 1 and the second housing 2. At the same time, after the first side 21 of the second housing 2 comes into contact with the rubber pad in the limiting groove 61, the rubber pad can clamp the first side 21 of the second housing 2 into the limiting groove 61 to improve the stability of the connection between the first housing 1 and the second housing 2.

[0024] In one or more embodiments, the first housing 1 is provided with an elastic member 7, which is used to push against the second side 22 of the second housing 2. With the help of the elastic force of the elastic member 7, the first side 21 of the second housing 2 moves into the limiting groove 61 and abuts against the groove plate 6; the first housing 1 is provided with a relief groove 11 for accommodating the elastic member 7.

[0025] See Figure 2 , Figure 3 , Figure 5 The elastic element 7 can be a spring, and it has a first end and a second end. The first end of the elastic element 7 is fixedly installed in the clearance groove, and the second end is fixedly installed on the second side 22 of the second housing 2. In the initial state, with the help of the elastic force of the elastic element 7, the second housing 2 can cover the opening of the first housing 1 and place the first side 21 of the second housing 2 in the limiting groove 61. When the plug connected to the second cable is inserted into the socket of the power strip 3, the second housing 2 needs to be controlled to overcome the elastic force of the elastic element 7 and rotate counterclockwise relative to the first housing 1; this setting can further improve the stability of the first housing 1 and the second housing 2 in terms of waterproofing the power strip 3.

[0026] In one or more embodiments, the top of the first housing 1 is provided with a fastener 8 for fixing the first side 21 of the second housing 2 into the limiting groove 61. See also Figures 1 to 5 The fastener 8 can be a locking bolt, which is threaded onto the first housing 1 and abuts against the top of the second housing 2, or threaded onto the top of the second housing 2. This arrangement can prevent the first side 21 of the second housing 2 from disengaging from the limiting groove 61 and causing the power strip 3 to be exposed, thereby further improving the waterproof effect of the power strip 3.

[0027] In one or more embodiments, a sealing element is provided inside the first sleeve 4 and / or the second sleeve 5. The sealing element may be a sealing rubber gasket or a rubber airbag.

[0028] In one or more embodiments, the top of the first housing 1 is provided with an ear plate 9, which facilitates the vertical hanging of the first housing 1. In other possible embodiments, the ear plate 9 is located on the side of the first housing 1 away from its opening; with this arrangement, after the first housing 1 is hung, the second housing 2 is completely placed below the first housing 1, so as to further reduce the possibility of moisture entering the accommodating space.

[0029] In one or more embodiments, the first housing 1 and the second housing 2 are made of rigid plastic. The rigid, transparent plastic used for the first housing 1 and the second housing 2 reduces production costs and overall weight while providing insulation.
