[0019] Preferred embodiment.
[0020] This embodiment provides a waterproof and anti-detachment device for a car audio panel knob, including a first circuit board 10, a first potentiometer 40, and a first knob 50. The upper end of the first circuit board 10 is provided with a first fixing block 30, the first potentiometer 40 is sleeved on the outside of the first fixing block 30, the first knob 50 is disposed on the upper end of the first potentiometer 40, the upper end of the first circuit board 10 is provided with a first waterproof ring 20, the first waterproof ring 20 is sleeved on the outside of the first potentiometer 40, the lower end of the first waterproof ring 20 is provided with a plurality of first hooks 21, and the first circuit board is provided with a plurality of first hanging openings 11, with each first hook 21 corresponding to a first hanging opening 11.
[0021] Furthermore, the lower end of the first fixing block 30 is provided with a plurality of first slots 31, and the inner side of the first potentiometer 40 is provided with a plurality of first mounting slots 41. The first mounting slots 41 are provided with first hooks, and the first hooks correspond one-to-one with the first slots 31.
[0022] Furthermore, the upper end of the first knob 50 is provided with a first anti-detachment cover 60, the lower end of the first anti-detachment cover 60 is provided with a first limiting ring 61, the lower end of the first limiting ring 61 is provided with a plurality of second hanging openings 62, and the inner side of the first fixing block 30 is provided with a plurality of second hooks 32, with the second hanging openings 62 corresponding one-to-one with the second hooks 32.
