[0031] Combination Figure 1 and Figure 2A power adapter with a heat dissipation structure includes a protective shell 1 and an adapter body 2 slidably connected inside the protective shell 1. The protective shell 1 is provided with a protective mechanism, which includes a knob 11 rotatably connected to the top of the protective shell 1. A take-up roller 111 is fixedly connected to the bottom of the knob 11. A moving block 12 is slidably connected to the top of the protective shell 1. A slot 121 is provided on one side of the moving block 12. A toggle block 122 is slidably connected to the top of the protective shell 1.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example 1:

[0034] To address the issue that most existing power adapters lack protective terminals, making them susceptible to damage from external forces and thus affecting their lifespan, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, a protective cloth 112 is fitted over the outer side of the take-up roller 111. The moving block 12 is fixedly connected to the protective cloth 112. A locking block 123 is fixedly connected to the bottom of the actuating block 122. The locking block 123 slides in cooperation with the locking groove 121. A first spring 124 is fixedly connected to one side of the locking block 123. One end of the first spring 124 is fixedly connected to the inside of the protective shell 1. A pulling block 13 is slidably connected to the bottom of the protective shell 1. A fixing block 132 is fixedly connected to the top of the pulling block 13. A second spring 131 is fixedly connected to the top of the fixing block 132. One end of the fixing block 131 is fixedly connected to the inside of the protective shell 1. Two sets of fixing blocks 132 are provided. The top of the adapter body 2 is provided with a fixing groove 21. The fixing block 132 slides in the fixing groove 21. A spring rod 211 is fixedly connected to one side of the adapter body 2. One end of the spring rod 211 is fixedly connected to the inside of the protective shell 1. When the adapter body 2 is not in use, the pulling block 13 can be pulled up and the adapter body 2 can be pushed so that the adapter body 2 is inside the protective shell 1. After releasing the pulling block 13, under the action of the second spring 131, A set of fixing blocks 132 moves to the inside of the fixing groove 21 on the top of the adapter body 2. Then, the moving block 12 located on the top of the protective shell 1 moves. The moving block 12 drives the protective cloth 112 to move, which can close one side of the protective shell 1. The moving block 122 moves, so that the locking block 123 moves into the slot 121, thereby fixing the position of the moving block 12 and thus protecting the adapter body 2. When the adapter body 2 needs to be used, the moving block 122 can be moved so that the locking block 123 and the slot 121 are engaged. 1. Separate the protective cover 112 and turn knob 11 to store it, opening one side of the protective shell 1. Then pull the pull block 13 to separate the fixing block 132 from the fixing groove 21. Under the action of the spring rod 211, the adapter body 2 moves out of the protective shell 1. After releasing the pull block 13, the other set of fixing blocks 132 moves into the fixing groove 21, making the adapter body 2 stably positioned on one side of the protective shell 1. This achieves the effect of protecting the adapter body 2 and improves the service life of the adapter body 2.

[0035] Example 2:

[0036] To address the problem that existing power adapters often lack heat dissipation capabilities, potentially leading to heat buildup and reduced performance after prolonged use, this embodiment discloses the following technical solution, specifically as follows: Figure 1 and Figure 5As shown, the protective shell 1 has ventilation hole groups 14 on both the left and right sides. A knob 141 is rotatably connected to each of the left and right sides of the protective shell 1. A rotating disk 142 is fixedly connected to one side of each knob 141. A through-hole group 143 is provided on the rotating disk 142, matching the ventilation hole group 14. A heat-conducting plate 144 is fixedly connected inside the protective shell 1, located between the two rotating disks 142. During use, the heat generated by the adapter body 2 can be absorbed through the through-hole group 143. The heat is transferred to the outside of the protective shell 1 through the port assembly 143 and the vent assembly 14, which can provide a certain heat dissipation effect for the adapter body 2. When the heat dissipation function is not needed, the knobs 141 located on the left and right sides of the protective shell 1 can be rotated. The knobs 141 drive the rotating disk 142 to rotate, which will cause the port assembly 143 to be no longer connected to the vent assembly 14, thus closing the vent assembly 14. This achieves the function of dissipating the heat generated by the adapter body 2 during operation and improves the performance.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
