[0024] A fixed connection structure and its acoustic plastic shell, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a female head 10 and a male head 11, and a limiting component is provided between the female head 10 and the male head 11. The limiting component includes a clamping block 12, a connecting body 13, an anti-slip groove 14 and a pushing plate 15. The clamping block 12 is elastically connected to the male head 11 through the connecting body 13. The bottom surface of the clamping block 12 is provided with a clamping tooth. The wall surface of the female head 10 is provided with a plurality of connecting bodies 13. The pushing plate 15 is fixedly connected to the female head 10. The pushing plate 15 can push the connecting body 13 to deform so that the clamping teeth of the clamping block 12 are clamped into different In the anti-slip groove 14, the connector 13 forms an arc-shaped plate-like structure, the concave surface of the connector 13 faces the top surface of the female head 10, and the two ends of the connector 13 are respectively fixedly connected to the block 12 and the side wall surface of the male head 11, and the anti-slip groove 14 forms a notch with a triangular cross-section. The clamping teeth and the anti-slip groove 14 are used in conjunction with each other, and the clamping teeth and the block 12 are integrally formed. The pushing plate 15 forms a plate-like structure with an L-shaped cross-section, and the pushing plate 15 is fixedly connected to the top surface of the female head 10. The bending of the pushing plate 15 Part of it faces the outer convex surface of the connector 13. Specifically, the female head 10 is located on one side of the female head 10. When the male head 11 is engaged with the female head 10, the male head 11 slides along the female head 10. When the side wall of the male head 11 is flush with the female head 10, the clamping teeth of the clamping block 12 are directly opposite to the rightmost anti-slip groove 14 and are engaged with the anti-slip groove 14. As the male head 11 slides, the bent portion of the pushing plate 15 gradually contacts the connector 13. The connector 13 is deformed and bent by the pushing plate 15, and the clamping teeth of the clamping block 12 are connected. The connecting body 13 is pushed into another adjacent anti-slip groove 14, thereby realizing an elastic connection between the card block 12 and the male head 11. For the installation scenario where the upper shell and the base are snap-fitted and a sealing ring needs to be placed, it can ensure that a certain pressure is applied to the sealing ring, thereby ensuring the sealing effect. At the same time, it can adapt to sealing rings of different thicknesses within a certain range. The pushing plate 15 pushes the connecting body 13 to apply a pressure perpendicular to the female head 10 to the card block 12, so that the card teeth of the card block 12 are more stably snapped with the anti-slip groove 14.

[0025] like Figure 3 and Figure 5As shown, the limit assembly also includes a push rod 20, a sliding groove 21 and a side window 22. The wall surface of the male head 11 is provided with a sliding groove 21. The push rod 20 is fixedly connected to the block 12 and extends into the sliding groove 21. The other side wall of the male head 11 is provided with a side window 22, and the side window 22 is connected to the sliding groove 21. The push rod 20 forms a rectangular rod structure. The thickness of the push rod 20 is less than the height of the sliding groove 21. The push rod 20 extends to the side of the side window 22. By setting the push rod 20 integrally formed with the block 12, when the upper shell and the base are removed, first pull A gap is created between the base and the upper shell, and when the gap is opposite to the side window 22, a flat-blade screwdriver is inserted into the side window 22. The screwdriver contacts the push rod 20, causing the push rod 20 to move in the sliding groove 21, and then the push rod 20 can drive the card block 12 away from the female head 10, so that the card teeth of the card block 12 are separated from the anti-slip groove 14, and then when removing the base and the upper shell, there is no need to pull hard, which reduces the probability of breakage of the card block 12 and the connector 13. On the basis of ensuring a good clamping effect, the probability of removal damage is reduced, which is more friendly to the rear-end maintenance personnel and can be clamped repeatedly.

[0026] A plastic housing for an audio system, not shown in the figure, comprises an upper shell and a lower base, wherein all of the above-mentioned fixed connection structures are arranged between the upper shell and the lower base, wherein the female connector 10 is fixedly connected to the upper shell, and the male connector 11 is fixedly connected to the lower shell. By arranging the above-mentioned fixed connection structures, the sealing ring between the upper shell and the base is fully squeezed and deformed to ensure the sealing effect, and at the same time, it is convenient for disassembly and assembly during later maintenance, thereby reducing the probability of damage and fracture of the block 12 and the connector 13.

[0027] The working principle of the utility model is as follows: when the male head 11 is engaged with the female head 10, the male head 11 slides along the female head 10. When the side wall of the male head 11 is flush with the female head 10, the clamping teeth of the clamping block 12 are directly opposite to the rightmost anti-slip groove 14 and are clamped with the anti-slip groove 14. As the male head 11 slides, the bent portion of the squeezing and pushing plate 15 gradually contacts the connecting body 13. The connecting body 13 is deformed and bent by squeezing and pushing the squeezing and pushing plate 15. The clamping teeth of the clamping block 12 are pushed by the connecting body 13 into another adjacent anti-slip groove 14, thereby realizing an elastic connection between the clamping block 12 and the male head 11. For the installation scenario where the upper shell and the base are clamped and a sealing ring needs to be placed, it can ensure that a certain pressure is applied to the sealing ring so that the sealing ring is fully deformed to ensure the sealing performance.

[0028] When removing the upper shell and the base, first pull to create a gap between the base and the upper shell. After the gap is opposite to the side window 22, insert a flat-blade screwdriver into the side window 22. The screwdriver contacts the push rod 20 to make the push rod 20 move in the sliding groove 21, and then the push rod 20 can drive the block 12 away from the female head 10, so that the teeth of the block 12 are separated from the anti-slip groove 14, and then the base and the upper shell are removed.
