DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] See also Figure 1-5 The utility model provides a waterproof power adapter shell, including a shell 1, a shell cover 2 is detachably connected to the front end of the shell 1, two guide holes 3 are opened at the front end of the shell 1, a plurality of fixing grooves 4 are opened at the front end of the shell 1, two limit columns 5 corresponding to the guide holes 3 are fixedly connected to the rear end of the shell cover 2, a plurality of fixing bolts 6 corresponding to the fixing grooves 4 are rotatably connected to the front end of the shell cover 2, a USB socket 7 is installed at the rear end of the shell 1, a waterproof mechanism 8 corresponding to the USB socket 7 is arranged at the rear end of the shell 1, a magnet groove 9 is opened at the rear end of the shell 1, a plurality of evenly distributed heat dissipation fins 10 are fixedly connected to both sides of the shell 1, and a plug 11 is installed at the front end of the shell cover 2.

[0024] Further as Figure 4 As shown, it is worth specifically explaining that the shell 1 includes a main body layer 101, the outer wall of the main body layer 101 is fixedly connected with a reinforcement layer 102, the outer wall of the reinforcement layer 102 is fixedly connected with an antistatic layer 103, the reinforcement layer 102 is made of carbon fiber material, the carbon fiber has high strength and rigidity, and is very light, the antistatic layer 103 is made of antistatic polyvinyl chloride board, which can effectively remove static electricity and enhance the safety of the power adapter.

[0025] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that the outer wall of the limit column 5 is tightly fitted with the inner wall of the guide hole 3, and the limit column 5 and the guide hole 3 cooperate with each other to guide the installation of the shell 1 and the shell cover 2, so as to facilitate the rotation and installation of the fixing bolt 6 inside the fixing groove 4.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the multiple heat dissipation fins 10 are all made of silicon carbide ceramic material. The surface area of ​​the ceramic material has about 20% more pores than the metal heat sink, and has a larger contact area with the convection medium air. It can take away more heat in the same unit time and avoid the power adapter from operating at high temperature for a long time.

[0027] According to the above working process, it can be known that: by setting the fixing groove 4 and the fixing bolt 6 in cooperation, the shell 1 and the shell cover 2 are detachably connected, which is convenient for the later disassembly and maintenance of the power adapter. At the same time, the reinforcement layer 102 and the anti-static layer 103 are set to increase the strength and safety of the power adapter, effectively extending the service life of the power adapter.

[0028] Further as Figure 5 As shown, it is worth specifically explaining that the waterproof mechanism 8 includes a rotating shaft 801 fixedly connected to the rear end of the shell 1, and the outer wall of the rotating shaft 801 is rotatably connected to a waterproof plate 802, and an installation groove 803 is opened inside the waterproof plate 802. A spring 804 is fixedly connected to the front end of the inner wall of the installation groove 803, and an iron column 805 is fixedly connected to the front end of the spring 804. By setting the waterproof mechanism 8, the waterproof plate 802 is rotated when not in use, and the waterproof plate 802 covers the USB socket 7. The iron column 805 is magnetically connected to the magnet slot 9 to fix the position of the waterproof plate 802 to prevent water from entering the USB socket 7 and causing damage to the power adapter.

[0029] Further as Figure 5 As shown, it is worth explaining in detail that the front end of the waterproof plate 802 fits tightly with the rear end of the shell 1, and a sealing gasket is fixedly connected to the front end of the waterproof plate 802, so that the waterproof plate 802 seals the USB port to achieve a waterproof effect.

[0030] Further as Figure 5 As shown, it is worth explaining in detail that the front end of the iron column 805 is designed to be hemispherical. Under the action of the spring, the iron column 805 can flexibly expand and contract on the inner wall of the installation groove 803. The hemispherical design makes the contraction and engagement of the iron column 805 smoother.

[0031] This solution has the following working process: in actual use, the two limit columns 5 are aligned with the inner wall of the guide hole 3 and inserted so that the inner surface of the shell cover 2 and the shell body 1 are aligned, and then the fixing bolt 6 is rotated so that the fixing bolt 6 is rotated and connected to the inner wall of the fixing groove 4 to complete the installation connection of the shell cover 2 and the shell body 1. During use, the heat dissipation fins 10 can promptly take away the heat generated by the power adapter during operation, avoid its long-term high-temperature operation, and extend its service life. When not in use, the waterproof plate 802 is rotated, and the waterproof plate 802 covers the USB socket 7. The iron column 805 and the magnet slot 9 are magnetically connected to fix the position of the waterproof plate 802 to prevent the USB socket 7 from getting wet and causing damage to the power adapter.

[0032] In summary: by setting the fixing groove 4 and the fixing bolt 6 in cooperation, the shell 1 and the shell cover 2 are detachably connected, which is convenient for the later disassembly and maintenance of the power adapter. At the same time, the reinforcement layer 102 and the anti-static layer 103 are set to increase the strength and safety of the power adapter, and effectively extend the service life of the power adapter; by setting the waterproof mechanism 8, the waterproof plate 802 is rotated when not in use, the waterproof plate 802 covers the USB socket 7, the iron column 805 and the magnet slot 9 are magnetically connected, and the position of the waterproof plate 802 is fixed to prevent the USB socket 7 from getting water in and causing damage to the power adapter.
