[0019] 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.
[0020] See also Figure 1-4The utility model provides a technical solution: a power amplifier adjustment knob structure, comprising a base 1 and a connecting member 3 arranged in the base 1, a rotating cover 2 is arranged at the outer end of the base 1, the rotating cover 2 and the base 1 are detachably connected, a groove 8 is provided on the side wall of the rotating cover 2, a fixing screw 11 is passed through the groove 8, a symmetrical installation groove 4 is provided at the upper end of the base 1, a clamping groove 5 is provided on both sides of the installation groove 4, a movable groove 9 is provided at the lower end of the rotating cover 2, a matching clamping mechanism is provided in the clamping groove 5 and the movable groove 9, and the clamping mechanism causes the rotating cover 2 to be connected to the base 1; the base 1 is arranged inside the power amplifier, and the base 1 is arranged at the inner side of the base 1. A connecting piece 3 is fixedly connected inside, and the connecting piece 3 is matched and snap-fitted with the rotating adjuster on the electric board. A detachable rotating cover 2 is arranged on the outer side of the base 1. When the power amplifier is operated, the rotating cover 2 will age and wear, and then the rotating cover 2 needs to be replaced. When replacing, the fixing screws 11 are removed, and then the rotating cover 2 can be separated from the base 1 through the snap-fit mechanism, so as to facilitate the replacement of the rotating cover 2. After replacement, the rotating cover 2 is placed on the base 1. After the rotating cover 2 is inserted into the base 1, the snap-fit mechanism can match the rotating cover 2 and the base 1 to install each other, and then the fixing screws 11 are used to fix the snap-fit mechanism stably, so that the rotating cover 2 and the base 1 are firmly connected.
[0021] like Figure 4 As shown, the card connection mechanism includes: an insert block 12, which is symmetrically arranged in the movable groove 9, a first inclined surface 13 is provided at the upper end of the insert block 12, and a second inclined surface 14 is provided at the lower end of the insert block 12, and the insert block 12 is matched with the card groove 5; a plate 7, the plate 7 is slidably arranged in the card groove 5, a spring 6 is fixedly connected in the card groove 5, the spring 6 is fixedly connected to the plate 7, and the plate 7 is correspondingly arranged with the insert block 12; the insert block 12 is located in the movable groove 9 and slides left and right, and a spring is fixed in the card groove 5.
