[0028] The utility model provides a technical solution, such as Figure 1-Figure 4 As shown; a microphone fixing seat for educational and teaching speeches, comprising: an outer cylinder 1, a support rod 11 is installed on one side of the lower surface of the outer cylinder, a support seat 12 is installed below the support rod, and the support seat 12 is fixed on the podium.

[0029] In the embodiment of the utility model, the outer cylinder 1 can be used to facilitate the installation and maintenance of the internal structure of the inner cylinder 2 by means of the threaded connection with the inner cylinder 2. On the other hand, the support rod 11 and the support seat 12 can be used to fix the device on the podium to ensure the stability of the microphone fixation.

[0030] The inner cylinder 2 is inserted into the outer cylinder 1 and is threadedly connected to the outer cylinder 1. A bell mouth 21 is arranged at one end thereof, and a detection module 22 is arranged at one end inside thereof. The detection module 22 is located on one side of the bell mouth 21. An annular boss 23 is arranged on the outer surface thereof. A plurality of tension springs 231 are installed on one side of the annular boss 23. The tension springs 231 are evenly distributed. A folding adjustment groove 24 is opened on the side surface thereof and is evenly distributed and located on one side of the annular boss 23. A rubber soft plate 241 is slidably installed in the folding adjustment groove 24. One end of the rubber soft plate 241 is inserted into the inner cylinder 2. An annular baffle 242 is arranged on the outside thereof. The annular baffle 2 42 is slidably inserted into the folding adjustment groove 24 on the inner side and fixedly connected to the rubber soft plate 241. An annular magnet 25 is installed on its outer surface, and the annular magnet 25 is located on one side of the folding adjustment groove 24; one end of the folding adjustment groove 24 is opened on the outer surface of the inner cylinder 2, and the other end is opened on the inner surface of the inner cylinder 2, and the two grooves are connected through an oblique groove. The rubber soft plate 241 is embedded in the folding adjustment groove 24 on the outer surface of the inner cylinder 2, and is embedded in the folding adjustment groove 24 on the inner surface of the inner cylinder 2 through the oblique groove. The thickness of the rubber soft plate 241 is greater than the depth of the folding adjustment groove 24 on the inner surface of the inner cylinder 2.

[0031] In the embodiment of the utility model, by utilizing the setting of the folded adjustment groove 24 and arranging a strip-shaped rubber soft plate 241 inside the folded adjustment groove 24, when the microphone is inserted into the inner cylinder body 1, the rubber soft plate 241 can be squeezed by the microphone so that the rubber soft plate 241 is continuously inserted into the inner cylinder body 1 and contacts with the microphone, thereby increasing the contact area with the microphone and fixing the microphone in the inner cylinder body 1.

[0032] In the embodiment of the utility model, the magnetic force of the annular magnet 25 and the annular baffle 242 can ensure the fixed position of the rubber soft plate 241, avoid the problem of the microphone falling off the device due to slight drag, and also ensure the stability of the microphone fixation.

[0033] In the embodiment of the utility model, by making the thickness of the rubber soft plate 241 greater than the depth of the folded adjustment groove 24 on the inner surface of the inner cylinder 2, the rubber soft plate 241 can be lower than the inner diameter of the inner cylinder 2, and then the microphone can be used to squeeze the rubber soft plate 241 to fix it.

[0034] The micro reduction motor 26 is embedded in the end of the inner cylinder 2, and the adjusting screw 261 is installed at its rotating end; the sliding baffle 27 is slidably installed at one end of the inner cylinder 2, and a square sleeve 271 is installed on one side of the surface. The square sleeve 271 is threadedly sleeved on the adjusting screw 261 and is slidably connected to the inner cylinder 2. A cylindrical charging plug 272 is installed at the center of the other side surface. The cylindrical charging plug 272 consists of a positive terminal 2721, an insulating sleeve 2722 The insulating sleeve 2722 is sleeved on the positive terminal 2721, and the negative sleeve 2723 is sleeved on the insulating sleeve 2722. The outer diameter of the negative sleeve 2723 and the positive terminal 2721 are the same. The insulating sleeve 2722 is clamped between the negative sleeve 2723 and the positive terminal 2721, and the outer end of this part is an arc-shaped surface. The cylindrical charging plug 272 is movably inserted into the socket at the center of the end of the wireless microphone.

[0035] In the embodiment of the utility model, the micro reduction motor 26 is used to drive the rotation of the adjusting screw 261, so that the square sleeve 271 can push the sliding baffle 27 to move, so that the sliding baffle 27 drives the cylindrical charging plug 272 to be inserted into the charging slot at the end of the microphone, so that after the microphone is fixed to the device, it can be charged, so that the microphone can be used for a long time and the problem of insufficient power can be avoided.

[0036] In the embodiment of the utility model, the cylindrical charging plug 272 is arranged, which is cylindrical in shape as a whole, so that the cylindrical charging plug 272 can be conveniently connected to the microphone, thereby ensuring the smooth charging of the microphone and avoiding the problem of docking deviation. In addition, the insulating sleeve 2722 can be arranged to avoid the short circuit problem of the cylindrical charging plug 272.

[0037] In the embodiment of the utility model, the cylindrical charging plug 272 is arranged at the bottom of the inner cylinder 2, which can effectively prevent people from touching it and thus avoid the occurrence of electric shock.

[0038] As a microphone fixing base for educational and teaching speeches of the utility model, the inner diameter of the inner cylinder body 2 is the same as the outer diameter of the wireless microphone, thereby ensuring the stability of the microphone fixing.

[0039] As a microphone fixing seat for educational and teaching speeches of the utility model, one end of the outer cylinder 1 is movably inserted into the annular groove on the outer surface of the bell mouth 21, which can ensure the airtightness of the outer cylinder 1 after installation and ensure the airtightness of the device.

[0040] As a microphone fixing base for educational and teaching speeches of the utility model, the magnetic force between the annular magnet 25 and the annular baffle 242 is greater than the elasticity of the tension spring 231, so the stability of the microphone fixing can be ensured.

[0041] When using the utility model, the staff fixes the support base 12 to the podium and connects it to an external power source, and then the device can be used;

[0042] When the microphone is inserted into the inner cylinder 2, the outer wall of the microphone contacts the rubber soft plate 241, and the microphone is squeezed to generate friction. As the microphone continues to be inserted, the rubber soft plate 241 is gradually inserted into the inner cylinder 2 by friction and contacts the outer wall of the microphone, increasing the friction between the microphone and the microphone. When the microphone is fully inserted, the front end of the microphone fits with the horn 21.

[0043] At this time, as the rubber soft plate 241 is inserted into the inner cylinder 2, the rubber soft plate 241 drags the annular baffle 242 to move toward the annular magnet 25, and pulls the tension spring 231 to make it elastic. At the same time, when the microphone is inserted, the annular magnet 25 contacts the annular baffle 242, and uses the magnetic force of the annular magnet 25 to make the annular baffle 242 adsorbed onto the annular magnet 25;

[0044] When the microphone is inserted into the inner cylinder 2, after the detection module 22 detects that the microphone is inserted, it waits for a certain period of time to allow the microphone to be completely inserted into the inner cylinder 2, and then waits for a short period of time, and then controls the micro reduction motor 26 to work, so that it drives the adjustment screw 261 to work, and through the threaded connection between the adjustment screw 261 and the square sleeve 271, it pushes the square sleeve 271 to move, and then the square sleeve 271 pushes the sliding baffle 27 to move in the inner cylinder 2, and the cylindrical charging plug 272 moves and contacts with the rear end of the microphone, and then gradually inserts it into the charging port at the rear end of the microphone;

[0045] In this process, since the microphone is in a fixed state, the cylindrical charging plug 272 generates a certain thrust on the microphone during the insertion process, but the force is smaller than the magnetic force of the annular magnet 25, so the microphone is still fixed in the inner cylinder 2;

[0046] When the micro reduction motor 265 has worked for a certain period of time, it is controlled to stop working. At this time, the cylindrical charging plug 272 is fully inserted into the charging port at the rear end of the microphone. Then the charger can be controlled to charge the microphone through the cylindrical charging plug 272.

[0047] When the microphone needs to be taken out, the staff holds the front end of the microphone and then drags the microphone outward with force. As the staff exerts force, the microphone drags the rubber soft plate 241 outward and separates the annular baffle 242 from the annular magnet 25. When the microphone is loose, the staff can remove the microphone from the inner cylinder 2 for use.

[0048] When the device is implemented, the charger connected to the cylindrical charging plug 272 can be set on the support base 12 and connected to the external power supply through a relay, so as to facilitate the control of the operation and stop of the charger.
