Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, and in particular to a waterproof and sealed power adapter. Background Technology

[0002] In an era where modern electronic devices are ubiquitous, power adapters play an indispensable role as key components connecting electronic devices to power sources. They convert AC power from the mains into stable DC power required by electronic devices, providing continuous and reliable power support for various electronic devices such as mobile phones, tablets, laptops, and digital cameras, ensuring that these devices can operate normally.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In people's daily life and work, the use environment of power adapters is complex and diverse. For example, in humid environments such as kitchens and bathrooms, water vapor and splashing water droplets can easily come into contact with the power adapter. Existing non-sealed power adapters have gaps between their outer shell and internal circuit board, which cannot effectively prevent water vapor from entering. When water vapor enters the power adapter, it will gradually condense into water droplets and adhere to the surface of electronic components. Water is a good conductor, which can cause short circuits between components on the circuit board, causing power adapter failure and even potentially damaging connected electronic devices.

Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a waterproof and sealed power adapter, including a power adapter body 1. Adjustment boxes 2 are fixedly connected to both ends of the power adapter body 1. A control groove 3 is provided inside the adjustment box 2. An adjustment block 4 is slidably connected inside the control groove 3. A sealing shell 5 is slidably connected inside the power adapter body 1. Release grooves 6 are provided at both ends of the sealing shell 5. A limiting groove 7 is provided on one side of the release groove 6. A through groove 8 is provided on the side of the control groove 3 near the sealing shell 5. A limiting rod 9 is fixedly connected to the side of the adjustment block 4 near the sealing shell 5. The operator inserts the sealing shell 5 into the power adapter body 1 and aligns the limiting rod 9 with the inside of the limiting groove 7. Simultaneously, the operator pulls the adjustment block 4, causing the limiting rod 9 to insert into the limiting groove 7, thus fixing the sealing shell 5 and sealing the inside of the power adapter body 1 to prevent moisture infiltration.

[0022] Reference Figure 3 As shown in this embodiment: a sealing gasket 10 is installed on the side of the sealing shell 5 near the power adapter body 1. The sealing gasket 10 is installed on the edge where the sealing shell 5 contacts the power adapter body 1. When the sealing shell 5 is fully inserted into the power adapter body 1 and fixed, the sealing gasket 10 can effectively prevent moisture from seeping in from the gap between the sealing shell 5 and the power adapter body 1, further enhancing the sealing performance of the device. This design allows the present invention to maintain good working condition when used in humid or underwater environments.

[0023] Reference Figure 3 and Figure 4 As shown in this embodiment: the size of the limiting rod 9 is adapted to the size of the limiting groove 7, the surface of the limiting rod 9 is inserted into the interior of the limiting groove 7, and after the limiting rod 9 is inserted into the interior of the limiting groove 7, it can remain stable through friction and is not easy to fall off, thus avoiding failure or damage caused by water seepage, and improving the practicality and durability of the device.

[0024] Reference Figure 3As shown in this embodiment: guide grooves 11 are provided on both sides of the inside of the power adapter body 1, and guide blocks 12 are fixedly connected to both sides of the sealing shell 5. The surface of the guide block 12 is slidably connected to the inside of the guide groove 11. By sliding the guide block 12 inside the guide groove 11, a more stable installation is achieved. At the same time, the sliding connection method also makes it easier for workers to install and disassemble the sealing shell 5, improving work efficiency. In addition, the sliding cooperation between the guide block 12 and the guide groove 11 can also reduce the damage to the device caused by improper operation or external factors to a certain extent, further extending the service life of the device.

[0025] Reference Figure 5 As shown in this embodiment: a return spring 13 is fixedly connected to the side of the adjusting block 4 near the inside of the control groove 3, and the side of the return spring 13 away from the inside of the control groove 3 is fixedly connected to the adjusting block 4. When the operator pushes the adjusting block 4 into the inside of the control groove 3, the adjusting block 4 compresses the return spring 13 to store force, and drives the limit rod 9 to release the limit between it and the limit groove 7. When the operator aligns the limit rod 9 with the limit groove 7 and releases the adjusting block 4, under the action of the rebound force of the return spring 13, the limit rod 9 quickly and stably inserts into the inside of the limit groove 7, realizing a fast and reliable connection.

[0026] Reference Figure 5 As shown in this embodiment: both ends of the control groove 3 are provided with limiting grooves 14, and both ends of the adjusting block 4 are fixedly connected with limiting blocks 15. The surface of the limiting block 15 is slidably connected to the inside of the limiting groove 14. By sliding the limiting block 15 inside the limiting groove 14, the movement of the adjusting block 4 inside the control groove 3 is more stable and smooth. This sliding connection design not only enhances the stability of the device, but also makes the operation of the adjusting block 4 more flexible.

[0027] Working Principle: The operator inserts the sealing shell 5 into the power adapter body 1 and aligns the limiting rod 9 with the limiting groove 7. Simultaneously, the operator pulls the adjusting block 4, which moves the limiting rod 9 into the limiting groove 7, thus fixing the sealing shell 5 and sealing the interior of the power adapter body 1 to prevent moisture ingress. The sealing gasket 10 is installed at the edge where the sealing shell 5 contacts the power adapter body 1. Once the sealing shell 5 is fully inserted and fixed, the sealing gasket 10 effectively prevents moisture from seeping in through the gap between the sealing shell 5 and the power adapter body 1, further enhancing the sealing performance of the device. This design allows the device to maintain good working condition even in humid or underwater environments. Furthermore, the limiting rod 9, after being inserted into the limiting groove 7, remains stable through friction and is not easily dislodged, preventing malfunctions or damage caused by moisture ingress. This improves the practicality and durability of the device. The sliding of guide block 12 within guide groove 11 ensures a more stable installation. Simultaneously, the sliding connection facilitates the installation and disassembly of the sealing shell 5, improving work efficiency. Furthermore, the sliding fit between guide block 12 and guide groove 11 reduces the risk of device damage due to improper operation or external factors, further extending the device's service life. When the operator pushes adjustment block 4 into control groove 3, adjustment block 4 compresses and stores force on return spring 13, causing limit rod 9 to release its position from limit groove 7. When the operator aligns limit rod 9 with limit groove 7 and releases adjustment block 4, the return force of return spring 13 causes limit rod 9 to quickly and stably insert into limit groove 7, achieving a fast and reliable connection. The sliding of limit block 15 within limit groove 14 ensures smoother and more stable movement of adjustment block 4 within control groove 3. This sliding connection design not only enhances the stability of the device but also makes the operation of adjustment block 4 more flexible.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
