The bottom surface of the sliding block 405 is mounted with a sliding plate 402. A groove 408 is formed on the side of the sliding plate 402 close to the power amplifier body 1. A flip plate 409 is rotatably mounted below the inner side wall of the groove 408. The flip plate 409 is engaged with the card slot 9. In this embodiment, during the storage of the device, the flip plate 409 is flipped and stored inside the flip plate 409 on the sliding plate 402. At the same time, under the action of the spring 407, the sliding block 405 and the sliding plate 402 move upward, and then the flip plate 409 closes the side of the power amplifier device body 1 where the through slot 210 is opened, thereby avoiding the effect of dust and moisture in the air entering the interior of the power amplifier device body 1 during storage.

[0021] In a further embodiment, referring to Figures 1-6 A positioning frame 410 is installed below the sliding plate 402 near the side of the power amplifier device body 1, and the inner wall of the positioning frame 410 is in contact with the flip plate 409; In this embodiment, the flip plate 409 contacts the positioning frame 410 after being flipped, and the spring 407 gives an upward force to the sliding plate 402, the sliding block 405 and the flip plate 409.

[0022] In a further embodiment, referring to Figures 1-11A through slot 1 406 is provided on the side of the guide rail 2 404 away from the guide rail 1 401, a sliding frame 411 is installed on the front side of the sliding block 405, the sliding frame 411 is slidably arranged between the through slot 1 406 and the power amplifier device body 1, and a protective member 8 is installed between the sliding frame 411 and the power amplifier device body 1; a plug-in slot 2 5 is provided on the upper front side of the power amplifier device body 1, the protective member 8 includes a protective cover 801, a plug-in block 804 is provided on the upper side of the protective cover 801 close to the power amplifier device body 1, and a transfer plate 802 is installed on the side of the protective cover 801 away from the power amplifier device body 1, and a limiting slot 803 is respectively provided on the left and right sides of the transfer plate 802; The sliding frame 411 is in an "L" shape, and the sliding frame 411 is slidably arranged in the limiting groove 803, and the plug-in block 804 is plugged into the plug-in groove 5; In this embodiment, when the device needs to be stored, the plug-in block 804 is plugged into the plug-in slot 25 to limit the up and down movement of the protective cover 801, and the audio input connector 13 is stored inside the protective cover 801. Then, the sliding block 405 is pressed to separate the slot 9 and the flip plate 409 from each other, and the flip plate 409 is rotated and stored in the groove 408. Then, under the action of the spring 407, the sliding block 405 drives the sliding frame 411 to rise, and then the sliding frame 411 slides into the limit slot 803, thereby limiting the forward and backward movement of the protective cover 801, thereby achieving protection for the audio input connector 13 on the power amplifier device body 1.

[0023] In a further embodiment, referring to Figures 1-9 The bottom surface of the mounting block 2 is provided with a plug-in slot 3 6, and the top surface of the sliding block 405 is provided with a plug-in slot 1 403. The positioning member 7 is cooperatively installed between the plug-in slot 1 403 and the plug-in slot 3 6. The positioning member 7 includes an elastic band 701 and a clamping block 702. The top and bottom surfaces of the elastic band 701 are respectively provided with clamping blocks 702. The clamping blocks 702 are in a "convex" shape. The elastic band 701 contacts the side wall of the power amplifier device body 1, and a plurality of strip grooves are evenly provided on the elastic band 701. One card block 702 is carded in the plug-in slot three 6, and the other card block 702 is carded in the plug-in slot one 403; the plug-in slot three 6 matches the card block 702, and the plug-in slot one 403 matches the card block 702. The plug-in slot three 6 is provided with anti-slip grooves, and the plug-in slot one 403 is provided with anti-slip grooves, which further enhance the stability of the card block 702 when plugging into the plug-in slot three 6 and the plug-in slot one 403; A limit frame 11 is installed in the inner cavity of the second through slot 10, and an activated carbon filter plate 12 is slidably arranged in the second through slot 10. The outermost side of the activated carbon filter plate 12 is in the same vertical plane as the side wall of the power amplifier device body 1; Among them, the through slot 2 10 isolates dust and moisture in the air during use; In this embodiment, when the device is in use, the activated carbon filter plate 12 isolates dust and moisture from the air flowing between the inside and outside of the power amplifier device body 1. After the sliding support member 4 supports the power amplifier device body 1, the two clamping blocks 702 on the end face and bottom face of the elastic band 701 are respectively clamped with the plug-in slot 3 6 and the plug-in slot 1 403. At this time, the elastic band 701 is tightened by the two clamping blocks 702, and the elastic band 701 touches and positions the activated carbon filter plate 12. When the activated carbon filter plate 12 needs to be replaced, the two clamping blocks 702 are removed from the plug-in slot three 6 and the plug-in slot one 403 respectively, and then the activated carbon filter plate 12 is removed from the through slot two 10 for replacement, and then the positioning piece 7 is re-installed between the plug-in slot three 6 and the plug-in slot one 403.

[0024] The working principle of the present invention is as follows: during storage, the flip plate 409 is flipped and stored inside the flip plate 409 on the sliding plate 402. At the same time, the sliding block 405 and the sliding plate 402 move upward under the action of the spring 407. Then, the flip plate 409 seals the side of the power amplifier device body 1 where the through slot 2 10 is opened, thereby preventing dust and moisture in the air from entering the interior of the power amplifier device body 1 during storage, making the device dust-proof and water-proof. When the device is in use, the sliding block 405 is pressed downward so that the groove 408 and the power amplifier device body 1 are not on the same horizontal plane. Then, the flip plate 409 is flipped over so that an angle is formed between the flip plate 409 and the sliding plate 402, and the pressing on the sliding block 405 is released. Then, under the action of the spring 407, the sliding block 405 moves upward and drives the flip plate 409 to be inserted into the card slot 9. At this time, the positioning frame 410 restricts the flipping of the flip plate 409, so that the flip plate 409, the sliding plate 402 and the power amplifier device body 1 form a stable supporting relationship, reducing the contact area between the device and the desktop or the ground when in use, thereby effectively improving the heat dissipation performance of the device, and making the device foldable and unfoldable, and easy to place and store; When the device is in use, the activated carbon filter plate 12 isolates dust and moisture from the air flowing between the inside and outside of the power amplifier device body 1. After the sliding support member 4 supports the power amplifier device body 1, the two clamping blocks 702 on the end face and bottom face of the elastic band 701 are respectively clamped with the plug-in slot 3 6 and the plug-in slot 1 403. At this time, the elastic band 701 is tightened by the two clamping blocks 702, and the elastic band 701 touches and positions the activated carbon filter plate 12; When the activated carbon filter plate 12 needs to be replaced, the two clamping blocks 702 are removed from the plug-in slot 3 6 and the plug-in slot 1 403 respectively, and then the activated carbon filter plate 12 is removed from the through slot 2 10 for replacement. Then, the positioning member 7 is re-installed between the plug-in slot 3 6 and the plug-in slot 1 403, so that the device has the function of facilitating the replacement of the activated carbon filter plate 12; When the device needs to be stored, the plug-in block 804 is plugged into the plug-in slot 25 to limit the upward and downward movement of the protective cover 801, and the audio input connector 13 is stored inside the protective cover 801. Then, the sliding block 405 is pressed to separate the slot 9 and the flip plate 409 from each other, and the flip plate 409 is rotated and stored in the groove 408. Then, under the action of the spring 407, the sliding block 405 drives the sliding frame 411 to rise, and then the sliding frame 411 slides into the limit slot 803, thereby limiting the forward and backward movement of the protective cover 801, thereby protecting the audio input connector 13 on the power amplifier device body 1.
