[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods:

[0027] like Figure 1-2 As shown, the utility model provides an AC head for a car audio system that is easy to disassemble and assemble, comprising a car audio system 1, an AC interface 2 is fixedly connected to the upper rear side of the car audio system 1, an AC plug 3 is slidably inserted into the rear side of the AC interface 2, an AC power cord 4 is fixedly connected to the rear end of the AC plug 3, a fixed card slot 21 is provided on both the left and right sides of the rear end surface of the AC interface 2, a dustproof mechanism 22 is provided on the rear side of the inner surface of the AC interface 2, a fixing mechanism 32 is movably connected to both the left and right sides of the AC plug 3, a power plug 31 is fixedly connected to the front side of the middle part of the AC plug 3, and the power plug 31 is slidably inserted into the inner surface of the AC interface 2;

[0028] When the car audio 1 is in use, the AC plug 3 is inserted into the inner side of the AC interface 2 through the power plug 31, and can be connected to the AC interface 2. The AC plug 3 can be fixed through the cooperation between the fixing mechanism 32 and the fixing slot 21, so that the car audio 1 can be powered by the AC power cord 4, which facilitates the use of the car audio 1.

[0029] like Figure 3As shown, the utility model provides an AC head for car audio that is easy to disassemble and assemble. The fixing mechanism 32 includes a button 321. The outer surface of the AC plug 3 is provided with a sliding groove 1 on both sides. The button 321 is slidably connected to the inside of the sliding groove 1. The opposite surfaces of the two buttons 321 are movably connected with a push rod 322. The end of the push rod 322 away from the button 321 is movably connected with a sliding pull plate 323. The front end surface of the AC plug 3 is provided with a sliding groove 2 on both sides. The sliding pull plate 323 is slidably connected to the inside of the sliding groove 1 and the front end penetrates to the sliding pull plate 323. The left and right sides of the front end of the sliding plate 323 are movably connected with a pulling rod 324 inside the second slot, and the end of the pulling rod 324 away from the sliding plate 323 is movably connected with a sliding hook 325. The sliding hook 325 is slidably connected to the inside of the sliding slot 2 and the front end thereof penetrates into the inside of the fixed slot 21. The side of the sliding hook 325 away from the pulling rod 324 is fixedly connected with a tensioning column 326. The outer surface of the tensioning column 326 is fixedly connected with a tensioning spring 327. The end of the tensioning spring 327 away from the tensioning column 326 is fixedly connected to the inner wall of the second sliding slot.

[0030] When the AC plug 3 is connected, the sliding hook 325 will be inserted into the interior of the fixed slot 21, and the tensioning column 326 will be tightened by the tensioning spring 327, so that the sliding hook 325 can be pulled to clamp the interior of the fixed slot 21, thereby fixing the AC plug 3 and preventing the AC plug 3 from loosening. When removing, the button 321 can be squeezed to push the sliding pull plate 323 to slide through the pushing rod 322, which facilitates the sliding hook 325 to be pulled back by the pulling rod 324, so that the AC plug 3 can be pulled out, which facilitates the use of the car audio 1.

[0031] like Figure 4-5As shown, the utility model provides an AC head for car audio that is easy to disassemble and assemble. The dustproof mechanism 22 includes two sliding baffles 221. The inner surface of the AC interface 2 is provided with sliding grooves 3 on both upper and lower sides. The sliding baffle 221 is slidably connected to the inside of the sliding groove 3. The left and right sides of the sliding baffle 221 are fixedly connected with oblique sliding blocks 222. The inner wall of the sliding groove 3 is provided with oblique sliding grooves 223 on both left and right sides. The oblique sliding blocks 222 are slidably connected to the inside of the oblique sliding groove 223. The opposite surfaces of the two sliding baffles 221 are fixedly connected with sealing pads 224. The front side of the sliding baffle 221 is fixedly connected with a telescopic top rod 225. The front end of the telescopic top rod 225 is slidably connected to the inside of the oblique sliding groove 223. A guide slide column 226 is connected to the guide slide column 226, and the upper and lower ends of the guide slide column 226 are fixedly connected to the inner wall of the sliding groove 3. The telescopic push rod 225 includes a sliding column 2251, and the sliding column 2251 is fixedly connected to the front side of the sliding baffle 221. The front end outer surface of the sliding column 2251 is slidably connected with a sliding sleeve 2252. The inner front end of the sliding sleeve 2252 is provided with a connecting groove 2253 that is connected up and down. The inner surface of the connecting groove 2253 is slidably connected to the outer surface of the guide slide column 226. The front end of the sliding column 2251 is fixedly connected with a tensioning spring 2254, and the front end of the tensioning spring 2254 is fixedly connected to the inner wall of the sliding sleeve 2252.

[0032] When the car audio 1 is in use, the sliding post 2251 can be tightened against the sliding baffle 221 by the tightening spring 2254, thereby driving the upper and lower sliding baffles 221 to block the inside of the AC interface 2, which can prevent dust from entering the inside of the AC interface 2. When the AC plug 3 is inserted, the sliding baffle 221 will be pushed to slide, so that the sliding post 2251 slides toward the inside of the sliding sleeve 2252, and the sliding of the inclined sliding block 222 in the inclined sliding groove 223, and the relative sliding between the connecting groove 2253 and the guide sliding post 226 can make the sliding baffle 221 shrink into the inside of the sliding groove three, thereby not affecting the connection between the AC interface 2 and the AC plug 3, ensuring the normal use of the car audio 1, and making the use of the car audio 1 more convenient.

[0033] The following is a detailed description of the working principle of this easily disassembled AC head for car audio.

[0034] like Figure 1-5As shown, by blocking the inside of the AC interface 2 with the sliding baffle 221, dust can be prevented from entering the inside of the AC interface 2. When the car audio 1 is in use, the AC plug 3 is inserted into the inner side of the AC interface 2 through the power plug 31, and the sliding baffle 221 will be pushed to slide, so that the sliding baffle 221 can be retracted into the inside of the sliding groove 3 by the sliding of the inclined sliding block 222 in the inclined sliding groove 223, which facilitates the connection between the AC plug 3 and the AC interface 2. At the same time, the sliding hook 325 can be inserted into the inside of the fixed slot 21, and the tensioning column 326 can be tightened by the tensioning spring 327, so that the sliding hook 325 can be pulled to clamp the inside of the fixed slot 21, so that the AC plug 3 can be fixed, and the car audio 1 can be powered by the AC power cord 4, which facilitates the use of the car audio 1.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
