[0018] Embodiment 1

[0019] As Figures 1 to 6 shown, the present utility model discloses a plug protection structure of a power adapter. The technical solution adopted is as follows: it includes a power adapter body 1. A plug 2 is arranged on the upper part of the front side of the power adapter body 1. Rotating shafts 101 are respectively and fixedly arranged on the upper parts of the left and right side surfaces of the power adapter body 1, and the rotating shafts 101 are horizontal with the height of the plug 2; the upper ends of adjusting arms 3 are hinged on the rotating shafts 101. Positioning concave holes 102 are respectively formed on the left and right side surfaces of the power adapter body 1. Positioning balls 301 are arranged on the inner side surfaces of the adjusting arms 3, and the positioning balls 301 can be clamped into the positioning concave holes 102. The positions of the adjusting arms 3 can be fixed through the positioning concave holes 102 and the positioning balls 301. The positioning concave holes 102 are located directly in front of and directly below the rotating shafts 101; the lower ends of the adjusting arms 3 are hinged with covers 4. The two covers 4 can be combined into a cuboid with a hollow interior and an opening at the rear side, and the combined cuboid can completely cover the plug 2. The cover 4 and the adjusting arm 3 are in a damping hinge connection, and the angle of the cover 4 can be conveniently controlled through the damping hinge connection method; the two covers 4 are connected through a connecting unit 5. The connecting unit 5 includes a chute 51, a slider 52 and a clamping seat 53. The chute 51 is arranged on one of the covers 4. The slider 52 is slidably arranged in the chute 51. The clamping seat 53 is correspondingly arranged on the other cover 4. The slider 52 can be slidably arranged in the clamping seat 53 when the two covers 4 are combined into a cuboid, connecting the chute 51 and the clamping seat 53 into one body. The slider 52 is used to prevent the connection between the chute 51 and the clamping seat 53, so as to connect the two covers 4. A limiting structure is arranged inside the chute 51, and the limiting structure limits the sliding degree of the slider 52. By limiting the slider 52, it can be prevented that the slider 52 slides out of the chute 51 when the clamping seat 53 is not connected. The plug 2 is protected by the cuboid formed by the two covers 4. The position of the cover 4 can be changed by the adjusting arm 3, so as to protect the plug 2 or expose the plug 2 for use. The connecting unit 5 can prevent the two covers 4 from separating when covering the plug 2.

[0020] Working principle of the present utility model: When it is necessary to protect the plug 2, rotate the adjusting arm 3 to make the positioning ball 301 leave the lower positioning concave hole 102, and then enter the front positioning concave hole 102, thereby fixing the adjusting arm 3. Grasp the cover 4 and rotate it so that the rear side of its opening contacts the front side of the power adapter body 1. The two covers 4 cover the plug 2. Finally, push the slider 52 and push it into the card seat to connect the two covers 4 to protect the plug 2.
