Therefore, they should not be construed as limitations on this utility model.
[0022] This embodiment provides a waterproof structure for a power adapter, including a protective shell 1 and a fixing connection mechanism 2. The protective shell 1 is a cavity structure with a side opening. The fixing connection mechanism 2 is located inside the protective shell 1 at the end away from the opening. A wire opening 3 is provided through the bottom wall of the protective shell 1, and the wire opening 3 is connected to the opening structure.
[0023] In one embodiment, the fixed connection mechanism 2 specifically includes a rotating rod 4, a partition 5, a lead screw nut 6, a lead screw 7, a fixing block 8, and a suction cup mechanism 9. The partition 5 is located on the inner wall of the protective housing 1 at the end away from the opening, and there is a space between the partition 5 and the inner wall of the protective housing 1. The fixing block 8 is located on the bottom wall of the protective housing 1 and is located between the partition 5 and the inner wall of the protective housing 1. The lead screw 7 is rotatably located in the fixing block 8. The lead screw nut 6 is sleeved on the lead screw 7. The suction cup mechanism 9 is fixedly connected to the lead screw nut 6 and is movable through the partition 5. The rotating rod 4 is located on the top of the protective housing 1 and is fixedly connected to the lead screw 7. Side rods 15 are symmetrically provided at both ends of the rotating rod 4. A stabilizing plate 16 is sleeved on the rotating rod 4 and is located on the top of the protective housing 1.
[0024] In one embodiment, specifically, an auxiliary adsorption mechanism 10 is movably connected through the partition 5. The auxiliary adsorption mechanism 10 has the same structure as the suction cup mechanism 9. A connecting rod 11 is provided between the auxiliary adsorption mechanism 10 and the suction cup mechanism 9. The auxiliary adsorption mechanism 10 includes a suction cup 12 and a slider 13. The slider 13 is movably connected through the partition 5. The suction cup 12 is fixedly connected to the slider 13. Sleeves 14 are sleeved at both ends of the connecting rod 11. The sleeves 14 are provided on the side of the connection end of the suction cup 12 and the slider 13. The slider 13 in the suction cup mechanism 9 is fixedly connected to the lead screw nut 6.
[0025] The working process of the waterproof structure of the power adapter in this embodiment is as follows: The rotating rod 4 is rotated by the side rod 15, which in turn drives the lead screw 7 to rotate. The lead screw 7 drives the suction cup mechanism 9 and the auxiliary adsorption mechanism 10 to move vertically inside the protective shell 1 through the lead screw nut 6, ensuring that both sets of suction cups 12 can be adsorbed and fixed on the back of the power adapter, thereby completing the connection between the power adapter and the waterproof structure. At the same time, the power adapter's wire is connected to the device through the wire opening 3. Then, the user directly plugs the power adapter and the protective shell 1 into the socket. At this time, the protective shell 1 is in direct contact with the wall or has a very small gap, thereby reducing the contact between the power distribution unit and the outside air, thus achieving waterproofing.
[0026] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
