DETAILED DESCRIPTION
[0015] The following is combined with Figure 1-4 This application is described in further detail.
[0016] The present application embodiment discloses a sound dustproof mechanism, referring to Figure 1-4, including a bottom plate 11, a limit frame 14 and a movable rod 22, a sound body 12 is fixedly installed in the middle of the top of the bottom plate 11, and the bottom plate 11 can be used to support the sound body 12. After the sound body 12 is connected to an external power source and is connected to an external computer host through a wire, music is selected by operating the computer host, and then it can be played using the sound body 12. The top of the sound body 12 is fixedly connected to a top plate 13, and the limit frame 14 is located outside the top plate 13. The limit frame 14 cooperates with the sound body 12 to form a circular hole. Both ends of the top of the bottom plate 11 are fixedly connected to fixed rods 15, and the tops of the two fixed rods 15 are respectively fixedly connected to the two ends of the bottom of the limit frame 14. The two fixed rods 1 The limit frame 14 can be supported and fixed. A circular groove is provided at the edge of the top of the bottom plate 11. A wire filter frame 21 is movably inserted into the circular groove. During the operation of the sound body 12, the wire filter frame 21 can block external dust to prevent external dust from adhering to the sound body 12. The two ends of the top of the movable rod 22 are respectively fixedly connected to the two ends of the top of the wire filter frame 21. The wire filter frame 21 can be pulled out of the circular hole by holding the movable rod 22 to clean the dust. The bottom end of the limit frame 14 is movably connected to a rubber telescopic cover 23. The bottom end of the rubber telescopic cover 23 is fixedly connected to the circular frame 24. The rubber telescopic cover 23 and the circular frame 24 are both movably connected. The circular frame 24 is sleeved on the outer surface of the sound body 12, and the bottom end of the circular frame 24 is fitted with the top end of the bottom plate 11. The two inner side walls of the circular frame 24 are respectively fitted with one side of the two fixing rods 15. The two fixing rods 15 cooperate to limit the circular frame 24, so that the circular frame 24 remains in a horizontal state during lifting. Both sides of the limiting frame 14 are provided with fixing components 3 for fixing the circular frame 24. The two fixing components 3 are composed of a fixing block 31 and a screw 32. Both sides of the circular frame 24 are provided with jacks. The two fixing blocks 31 are respectively fixedly connected to the two sides of the limiting frame 14. The two screws 32 are respectively threaded through the two fixing blocks 31. The diameters of the two screws 32 are less than The aperture of the two jacks is such that the circular frame 24 is pushed upward to compress the rubber telescopic cover 23, so that the movable rod 22 is exposed outside, and at the same time, one end of the two screws 32 is rotated and inserted into the two jacks respectively, so that the circular frame 24 and the rubber telescopic cover 23 can be limited, so that the wire filter frame 21 is exposed outside, and at the same time, it is avoided that the music played and transmitted by the audio body 12 is blocked. When not in use, the two screws 32 are rotated to make the two screws 32 detach from the two jacks. At this time, the fixation of the circular frame 24 can be released, and then the circular frame 24 falls and drives the rubber telescopic cover 23 to stretch out and completely cover the wire filter frame 21. In this way, in cooperation with the wire filter frame 21, the audio body 12 can be doubly protected from dust.
[0017] Reference Figure 1 and Figure 2 The bottom ends of both sides of the two limit frames 14 are fixedly connected with toggle blocks 5, and the circular frame 24 can be easily raised and lowered by holding the two toggle blocks 5.
[0018] Reference Figure 1 and Figure 2 The four corners at the bottom of the bottom plate 11 are fixedly connected with supporting feet 4, and the four supporting feet 4 can cooperate to support the bottom plate 11 in the air to prevent the bottom plate 11 from contacting the ground, so that it is convenient for the staff to lift the bottom plate 11 and drive the sound body 12 to move the position.
[0019] The implementation principle of the dustproof mechanism of the audio system of the present application embodiment is as follows: when in use, the circular frame 24 is pushed upward to compress the rubber telescopic cover 23, so that the movable rod 22 is exposed to the outside, and at the same time, one end of the two screws 32 is respectively rotated and plugged into the two sockets, so that the circular frame 24 and the rubber telescopic cover 23 can be limited, so that the wire filter frame 21 is exposed to the outside, and at the same time, the music played and transmitted by the audio main body 12 is avoided from being blocked. During the operation of the audio main body 12, the wire filter frame 21 can block the dust from the outside and prevent the dust from the outside from adhering to the audio main body 12;
[0020] When the audio body 12 is not in use, the two screws 32 are rotated to disengage the two screws 32 from the two jacks. At this time, the fixation of the circular frame 24 can be released. Then the circular frame 24 falls and drives the rubber telescopic cover 23 to extend to completely cover the wire filter frame 21. In this way, the audio body 12 can be doubly protected from dust in cooperation with the wire filter frame 21.
