Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-3 The utility model provides an embodiment of a power supply waterproof structure, comprising a power strip 1, a socket 2 is provided on the top of the power strip 1, power is transmitted through the socket 2, a protective cover 3 is rotatably connected to the rear end of the power strip 1, the bottom of the protective cover 3 is fitted with the top of the power strip 1, so that the protective cover 3 can close the power strip 1, a slide groove 4 is provided inside the protective cover 3, a plurality of springs 5 ​​are provided on the inner wall of the slide groove 4, a plurality of limiting blocks 6 are slidably connected to the inner wall of the slide groove 4, the limiting block 6 is limited by the slide groove 4, one end of the spring 5 is fixedly connected to the inner wall of one side of the slide groove 4, and the other end of the spring 5 is fixedly connected to one side of the limiting block 6, the spring 5 can be squeezed by the movement of the limiting block 6 so that the spring 5 is deformed to generate elastic potential energy, a sealing column 7 is fixedly connected to the bottom of the limiting block 6, the outer side of the sealing column 7 is slidably connected to the inner wall of the protective cover 3, and the control rod 10 can be pushed by the contraction of the sealing column 7.

[0023] The outsides of multiple sealing columns 7 fit together for the purpose of sealing. An extension block 8 is fixedly connected to the bottom of the protective cover 3. A card hole 9 is opened on the outside of the extension block 8. The design of the extension block 8 can fix the power strip 1 and the protective cover 3. The right end of the power strip 1 is slidably connected to a control rod 10, and the left end of the control rod 10 is fixedly connected to a push plate 11. The push plate 11 can be moved by moving the control rod 10. The left end of the push plate 11 is rotatably connected to a connecting rod 12, and when the push plate 11 moves, the connecting rod 12 can be rotated. The left end of the connecting rod 12 is rotatably connected to a card plate 13, and the card plate 13 can be moved by rotating the connecting rod 12. The outside of the card plate 13 is engaged with the inner wall of the card hole 9, so that the extension block 8 is fixed, so that the protective cover 3 is fixed to the top of the power strip 1, and the left end of the card plate 13 is fixedly connected to a telescopic component.

[0024] A groove 15 is provided inside the power strip 1, and the telescopic assembly includes a telescopic block 14 and a second spring 16. The right end of the telescopic block 14 is fixedly connected to the left end of the card plate 13, and the telescopic block 14 can be moved by the movement of the card plate 13. The outside of the telescopic block 14 is slidably connected to the inner wall of the groove 15, so that the telescopic block 14 can be restricted. The second spring 16 is arranged inside the groove 15, and one end of the second spring 16 is fixedly connected to the inner wall of one side of the groove 15, and the other end of the second spring 16 is fixedly connected to one side of the telescopic block 14. The movement of the telescopic block 14 can squeeze the second spring 16 so that the second spring 16 can store elastic potential energy. The outside of the push plate 11 is slidably connected to the inner wall of the groove 15, so that the push plate 11 can stably push the connecting rod 12 to rotate, and the outside of the card plate 13 is slidably connected to the inner wall of the groove 15, so that the card plate 13 can stably engage the card hole 9.

[0025] Working principle: when the power socket 1 needs to be used, the control rod 10 is pressed, and the push plate 11 can be pushed to move. The movement of the push plate 11 can lead to the rotation of the connecting rod 12, and the rotation of the connecting rod 12 can move the card plate 13. At this time, the movement of the card plate 13 can lead to the movement of the telescopic block 14 and squeeze the spring 2 16 through the telescopic block 14, so that the spring 2 16 is deformed to generate elastic potential energy for subsequent reset energy storage. At this time, the card plate 13 will withdraw from the inner wall of the card hole 9 under the movement, so that the protective cover 3 can be opened. At this time, other electrical appliances are inserted into the socket 2 for use, and the protective cover 3 is closed during the use process. The protective cover 3 is closed, and the movement of the protective cover 3 can move the sealing column 7, and the power cord can be pushed by the sealing column 7. At this time, the sealing column 7 will push the limiting block 6 upward according to the size of the power cord, so that the limiting block 6 can squeeze the spring 1 5 to move the sealing column 7 and adapt to the power cord, so that the power cord is close to the top of the power strip 1, so that a seal can be formed between the power strip 1 and the protective cover 3 to prevent external water and moisture from entering. At this time, the extension block 8 can push the card plate 13, because the head of the card plate 13 is rounded, so that the card plate 13 shrinks with the telescopic block 14, and when it reaches the appropriate position, the spring 2 16 will push the telescopic block 14 to reset the card plate 13 and engage with the inner wall of the card hole 9.
