[0032] Reference Figure 1 As shown, the utility model provides a technical solution: a power adapter with an anti-foolproof structure, including a shell 1, a USB interface 4, a pin 5 and a USB plug 6, an anti-foolproof device 2 is provided on the outside of the shell 1, and a rotating device 3 is provided on the outside of the shell 1.

[0033] The specific settings and functions of the fool-proofing device 2 and the rotating device 3 are described in detail below.

[0034] Reference Figure 2 and Figure 3 As shown, in this embodiment, the foolproofing device 2 includes a fixed frame 201, one side of which is fixedly connected to the housing 1. A guide slot 202 is defined on one side of the fixed frame 201. A guide block 203 is slidably connected within the guide slot 202. One end of the guide block 203 is fixedly connected to the USB plug 6. Two guide slots 204 are defined on one side of the fixed frame 201. Guide blocks 205 are slidably connected within the guide slots 204. One end of each guide block 205 is fixedly connected to the USB plug 6. This allows the USB plug 6 to move toward the USB port 4, driving the guide blocks 203 and 205 into the guide slots 202 and 204, respectively. A fixed block 206 is fixedly connected to one side of the fixed frame 201. Round rods 208 are fixedly connected to both sides of the fixed block 206. This ensures that the fixed frame 201 and the fixed block 206 are fixedly secured, and the fixed block 206 and the round rods 208 are fixedly secured. One end of the round rod 208 is fixedly connected to an L-shaped block 211, and the ends of the two L-shaped blocks 211 that are close to each other are fixedly connected to the fixed frame 201. This achieves the effect of fixing the fixed frame 201 and the L-shaped block 211, and fixing the L-shaped block 211 and the round rod 208. The circular arc surface of the round rod 208 is slidably connected to the movable plate 209, and one side of the movable plate 209 is fixedly connected to the L-shaped plate 210. This achieves the effect of the L-shaped plate 210 moving and driving the movable plate 209 to slide on the round rod 208. The circular arc surface of the round rod 208 is covered with a spring 207, and the two ends of the spring 207 are fixedly connected to the fixed block 206 and the movable plate 209 respectively. This achieves the effect of preventing the round rod 208 from deforming the spring 207 during the extension or contraction process. The ends of the two L-shaped plates 210 that are close to each other are fixedly connected to an arc-shaped clamping plate 212, and the arc surface of the arc-shaped clamping plate 212 is fixedly connected to an anti-skid pad 213. The side of the two anti-skid pads 213 that are close to each other is slidably connected to the USB plug 6. The anti-skid pads 213 achieve the effect of increasing friction.

[0035] Reference Figure 4As shown, in this embodiment: the rotating device 3 includes two support blocks 31, one end of the two support blocks 31 is fixedly connected to the housing 1, and the side of the two support blocks 31 close to each other is fixedly connected to a fixing rod 32, and the arc surface of the fixing rod 32 is fixedly connected to two limiting rings 33. The limiting rings 33 and the fixing rod 32 are fixed. The arc surface of the fixing rod 32 is rotatably connected to a support plate 34, and one side of the support plate 34 is fixedly connected to a rubber block 35. The rubber block 35 moves to drive the support plate 34 to rotate around the fixing rod 32. Two protective grooves 36 are provided on one side of the rubber block 35, and the interior of the protective groove 36 is slidably connected to the pin 5. The pin 5 is placed in the protective groove 36, so that the rubber block 35 protects the pin 5.

[0036] Working principle: Through the anti-foolproof device 2, when it is necessary to prevent the USB interface 4 and the USB plug 6 from being inserted reversely during the plugging process, the operator first fixes the guide block 203 and the guide block 205 on the USB plug 6. When the USB plug 6 is plugged into the USB interface 4, the operator first observes the position of the guide groove 202 and the guide groove 204 provided on the fixing frame 201, so that the guide block 203 and the guide block 205 on the USB plug 6 are opposite to the guide groove 202 and the guide groove 204, and the USB plug 6 is inserted in the direction of the USB interface 4, so that the guide block 203 and the guide block 205 slide in the guide groove 202 and the guide groove 204 respectively, which has a good anti-foolproof effect. Through the anti-foolproof device 2, the problem of a traditional power adapter being easily inserted reversely during plugging due to the lack of an anti-foolproof structure is solved.

[0037] By using the rotating device 3, when the power adapter is not in use and needs to prevent the pins 5 from being deformed and scratched, the operator first moves the support plate 34, which rotates around the fixed rod 32. During the rotation process, the rubber block 35 is driven to move toward the pins 5 until the pins 5 are placed in the protective groove 36 provided on the rubber block 35. By using the rotating device 3, the problem of a traditional power adapter with a foolproof structure, in which the pins 5 cannot be protected and are easily squeezed and scratched by surrounding objects, resulting in deformation and scratching of the metal pins 5, is solved.
