Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The preferred embodiment of this utility model features a power amplifier with a retractable transmission line structure, such as... Figure 1-5As shown, the amplifier includes an amplifier body 10 and a support base plate 20 located below the amplifier body 10. Specifically, the amplifier body 10 has a cuboid structure, and the support base plate 20 is rectangular and located directly below the amplifier body 10. A main data interface group is provided on the rear end face of the amplifier, consisting of a signal input 30, a signal output 40, and a power interface 50. Multiple support feet 60 are circumferentially distributed along the lower surface edge of the support base plate 20, specifically four support feet 60 located at the four corners of the support base plate 20. A sliding bracket 70 is slidably mounted on the rear end of the lower surface of the support base plate 20 in the front-to-back direction. A flip bracket 80 is longitudinally rotatably connected to the rear end, and an extension transmission line assembly 90 is provided on the flip bracket 80. When unfolded, the flip bracket 80 is located on the rear side of the support base plate 20. When folded, both the flip bracket 80 and the extension transmission line assembly 90 are located on the lower side of the support base plate 20. Compared with traditional power amplifiers, the amplifier provided by this solution can not only adapt to more external insertion requirements of transmission lines, but also, when not in use, the extension transmission line assembly 90 can be flipped downward by flipping the flip bracket 80 and reset with the sliding bracket 70, so that the extension transmission line assembly 90 can be stored at the bottom of the support base plate 20, thus making the overall structure simpler and more compact.

[0029] In this embodiment, the extended transmission line assembly 90 includes a housing 91, a circuit board (not shown) disposed within the housing 91, and multiple transmission line interfaces 92 vertically integrated on one side wall of the circuit board. In addition, the circuit board also integrates a switch 901 for cutting off or closing the multiple transmission line interfaces 92. The housing 91 is provided with through holes for the transmission line interfaces to pass through, and the housing 91 is connected to the flip bracket 80. When the transmission line interfaces are not needed, the transmission line interfaces 92 can be kept facing downwards by flipping the flip bracket 80 downwards by 180 degrees. This not only avoids the resetting action of the sliding bracket 70, but also prevents dust and foreign objects from falling into the transmission line interfaces 92.

[0030] In this embodiment, the flip bracket 80 has a positioning groove 801 for the positioning housing 91, and the housing 91 is detachably connected to the bottom surface of the positioning groove 801. Specifically, the flip bracket 80 includes a rectangular fixing plate 81 and a rotating shaft 82 connecting the fixing plate 81 and the sliding bracket 70. The fixing plate 81 is elongated, and the positioning groove 801 is provided on one side wall of the fixing plate 81 and penetrates the side wall of the fixing plate 81 away from the sliding bracket 70. The left and right ends of the positioning groove 801 also penetrate the left and right side walls of the fixing plate 81, thus forming a stepped structure. The rotating shaft 82 penetrates to the side wall of the positioning groove 801 near the sliding bracket 70 to facilitate installation and disassembly.

[0031] In this embodiment, the power amplifier with a retractable transmission line structure described in this solution also includes a positioning component 100 for positioning the extended transmission line assembly 90 when the flip bracket 80 is flipped to a horizontal state, so as to prevent the extended transmission line assembly 90 from accidentally flipping during use and to ensure convenient operation for the user.

[0032] In this embodiment, the positioning component 100 includes a magnet 101 and a ferromagnetic component 102 that attracts it. The magnet 101 and the ferromagnetic component 102 are respectively disposed on the end faces of adjacent ends of the sliding bracket 70 and the flipping bracket 80. Specifically, both the ferromagnetic component 102 and the magnet 101 are powerful magnets 101. Through the two powerful magnets 101 facing each other, the horizontality of the outer shell 91 can be maintained, and the positioning function can be cut off and the flipping can be performed at any time as needed by the user. It is convenient to operate and practical.

[0033] In this embodiment, two positioning components 100 are provided and are located on the left and right sides of the rotating shaft 82 of the flip bracket, respectively, so as to further stabilize the fixing plate 81 and the outer shell 91.

[0034] In this embodiment, the sliding bracket 70 is a cuboid slider. A groove 201 for sliding the slider is provided along the front-to-back direction on the lower surface of the support base plate 20. Adjustment components 110 for adjusting the sliding tightness of the slider are provided on the rear end of the support base plate 20 and on both the left and right sides of the groove 201. Specifically, the adjustment component 110 includes a T-shaped member 111, with its lateral end 11a arranged longitudinally. A T-shaped groove 120 adapted to the T-shaped member 111 is provided on the side wall of the slider, so that the lateral end 11a of the T-shaped member 111 can be engaged in the T-shaped groove 120 and limit the slider's movement. The supporting base plate 20 has an adjustment groove 130 on its rear end surface for the longitudinal end 11b of the T-shaped component 111 to move left and right. The adjustment assembly 110 also includes a fastening bolt 112 for fixing the longitudinal end 11b of the T-shaped component to the bottom surface of the adjustment groove 130. The longitudinal end 11b of the T-shaped component 111 has a relief hole 11c along its length direction to avoid the screw portion of the fastening bolt 112. When it is necessary to adjust the sliding resistance of the slider, loosen the fastening bolt 112, move the longitudinal end of the T-shaped component 111 away from the slider to tighten the slider, and tighten the fastening bolt 112 again after it is in place.

[0035] The slider has guide limiting grooves 71 arranged in the front-back direction on both the left and right side walls, and guide protrusions 2a adapted to the guide limiting grooves 71 are provided on the side wall of the slide groove 201. The smooth sliding of the slider and the limiting function can be ensured by the cooperation of the guide protrusions 2a on the left and right sides and the guide limiting grooves 71.

[0036] In this embodiment, the adjusting assembly 110 further includes an adjusting bolt 113 perpendicular to the longitudinal end. The adjusting bolt 113 is located on the upper side of the longitudinal end of the T-shaped member 111 and is longitudinally threaded to the supporting base plate 20. Multiple toothed grooves 140 are provided on the upper sidewall of the longitudinal end of the T-shaped member 111 along its length. A protruding tooth 150 engaging with the toothed groove 140 is provided on the peripheral sidewall of the head of the adjusting bolt 113. When assembled, the bolt and the longitudinal end of the T-shaped member 111 form a gear and rack engagement structure. When the sliding resistance of the slider needs to be adjusted to increase, the fastening bolt 112 is first loosened, and then the adjusting bolt 113 is tightened to drive the longitudinal end of the T-shaped member 111 away from the slider. After reaching the desired position, the fastening bolt 112 is tightened again, thus completing the adjustment of the sliding resistance of the slider. It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
