When a walking person accidentally pulls the connecting wire of the power amplifier, it is easy to cause the position of the connecting wire plug and the power amplifier socket to loosen, resulting in poor contact, and in severe cases, the connecting wire plug and the power amplifier socket may fall off. The sudden disconnection is more likely to cause damage to the audio system connected to the power amplifier, causing economic losses, thereby affecting the use effect.

[0004] The working principle of the above patent specification mentions that "the fixing plate 2 is moved to contact with the surface of the power amplifier body 1, and then the screw 7 is turned. The screw 7 is connected to the fixing plate 2 through a thread. When the screw 7 is rotated, the screw 7 can be moved. The screw 7 is moved to be in close contact with the surface of the power amplifier body 1. At this time, the fixing plate 2 can be connected to the power amplifier body 1."

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3The utility model provides an embodiment: a power amplifier for an audio system with a mounting structure, comprising a mounting plate 1, four corners of the mounting plate 1 are threadedly connected with bolts, and the outer threads of the bolts are threadedly connected with nuts. First, the mounting plate 1 is installed at a suitable position of the audio system using bolts and nuts. A power amplifier housing 2 is provided on the top of the mounting plate 1, and handles are fixedly connected to the left and right sides of the front end of the power amplifier housing 2. Then, the power amplifier housing 2 is placed on the top of the mounting plate 1 using the handles. A cavity 3 is provided inside the left and right sides of the mounting plate 1, and a spring 4 is provided inside the cavity 3. One end of the spring 4 is fixedly connected to one side of the inner wall of the cavity 3, and a card plate 5 is slidably connected to the bottom of the cavity 3. As the card plate 5 moves, the spring 4 is squeezed, and the other end of the spring 4 is fixedly connected to the outside of one side of the card plate 5. At this time, the spring 4 is compressed by force. The spring 4 absorbs external force during compression due to its own elastic properties. The top of the card plate 5 is rotatably connected with a connecting shaft 6, and the card plate 5 is driven to move to one side through the connecting shaft 6. The other end of the connecting shaft 6 is rotatably connected with a pull plate 7.

[0026] The connecting shaft 6 is driven to move under the pulling of the pulling plate 7, and the pulling plate 7 is pulled upward at the same time. The outside of the pulling plate 7 is slidably connected to the top through hole of the mounting plate 1. When the power amplifier housing 2 contacts the top of the mounting plate 1, the pulling plate 7 is released. The outside of the pulling plate 7 is slidably connected to the inside of the cavity 3. A card slot 8 is provided on the left and right sides of the power amplifier housing 2. The other side of the card plate 5 is engaged with the inner wall of the card slot 8. At this time, the spring 4 will release the external force absorbed during compression, so that the card plate 5 is tightly engaged with the card slot 8, so that the power amplifier housing 2 is fixed on the mounting plate 1. The power amplifier housing 2 can be fixed on the audio system and the power amplifier housing 2 can be conveniently removed without the help of external tools, thus saving operation time.

[0027] Reference Figure 1 Figure 4 , protective plates 9 are provided on both sides of the left and right sides of the power amplifier housing 2. When the protective plate 9 needs to be cleaned, telescopic components are provided inside the four corners of the protective plate 9, and the telescopic components include a cavity 10, a slide plate 11, a pull rod 12, a spring 13, two connecting rods 14 and two card plates 15. The pull rod 12 is pressed inward, and the cavity 10 is opened inside the protective plate 9. The outside of the slide plate 11 is slidably connected to the inner wall of the cavity 10. One side of the pull rod 12 is fixedly connected to one side of the slide plate 11. The outside of the pull rod 12 is slidably connected to the external through hole of the protective plate 9. One end of the spring 13 is fixedly connected to the other side of the slide plate 11. Under the push of the pull rod 12, the slide plate 11 squeezes the spring 13 inward, and one end of the connecting rod 14 is rotatably connected to the other side of the slide plate 11. At the same time, the connecting rod 14 rotates, and one side of the card plate 15 is rotatably connected to the other end of the connecting rod 14.

[0028] A limiting groove 16 is provided inside the protective plate 9, and the rotation drives the card plate 2 15 to move towards each other inside the limiting groove 16. The outsides of the two card plates 2 15 are slidably connected to the inner wall of the limiting groove 16. A plurality of card slots 2 17 are provided on the left and right sides of the power amplifier housing 2. The outside of the card plate 2 15 is engaged with the inner wall of the card slot 2 17. When the two card plates 2 15 are in contact, the card plate 2 15 is separated from the card slot 2 17, so that the protective plate 9 can be removed for cleaning. When installing, the protective plate 9 is placed on both sides of the power amplifier housing 2 again, and then the pull rod 12 is pressed. When one side of the protective plate 9 is in contact with the power amplifier housing 2, the pull rod 12 is released, and the spring 2 13 will release the external force absorbed during compression, so that the card plate 2 15 is engaged with the card slot 2 17, which can dissipate heat inside the power amplifier housing 2 while preventing dust and debris from entering the inside of the power amplifier housing 2, thereby ensuring the normal use of the power amplifier housing 2.

[0029] Working principle: First, install the mounting plate 1 at a suitable position of the audio system using bolts and nuts, then place the power amplifier housing 2 on the top of the mounting plate 1, and pull the pull plate 7 upwards at the same time. The pull of the pull plate 7 drives the connecting shaft 6 to move, and the connecting shaft 6 drives the card plate 5 to move to one side. As the card plate 5 moves, the spring 4 is squeezed. At this time, the spring 4 is compressed. Due to its own elastic properties, the spring 4 will absorb external force during compression. When the power amplifier housing 2 contacts the top of the mounting plate 1, release the pull plate 7. At this time, the spring 4 will release the external force absorbed during compression, so that the card plate 5 and the card slot 8 are tightly engaged, so that the power amplifier housing 2 is fixed. When the protective plate 9 on the mounting plate 1 needs to be cleaned, press the pull rod 12 inward, and the slide plate 11 squeezes the spring 2 13 inward under the push of the pull rod 12, and the connecting rod 14 rotates at the same time, and drives the card plate 2 15 to move toward each other inside the limit groove 16. When the two card plates 2 15 are in contact, the card plate 2 15 is separated from the card slot 2 17, so that the protective plate 9 can be removed for cleaning. When installing, place the protective plate 9 on both sides of the power amplifier housing 2 again, and then press the pull rod 12. When one side of the protective plate 9 is in contact with the power amplifier housing 2, release the pull rod 12, and the spring 2 13 will release the external force absorbed during compression, so that the card plate 2 15 is engaged with the card slot 2 17.
