[0023] Please see Figure 1-4In this utility model, a classroom sound pickup device that is easy to maintain includes a mounting base 1. Two first mounting plates 10 are fixedly connected to the inner top wall of the mounting base 1 by bolts. A circular buckle 11 is fixedly connected to the bottom surface of each first mounting plate 10. A connecting plate 9 is slidably connected inside the mounting base 1. The bottom surface of the connecting plate 9 is fixedly connected to the main body 2 of the sound pickup device. Two second mounting plates 12 are fixedly connected to the upper surface of the connecting plate 9. A set of arc-shaped plates 19 is fixedly connected to the upper surface of each second mounting plate 12. A through groove 17 is opened on the mutually distant side of each set of arc-shaped plates 19. A pin 18 is rotatably connected inside the two through grooves 17. A first clamping plate 15 and a second clamping plate 16 are rotatably connected to the outer surface of each pin 18. Each first clamping plate 15 and second clamping plate 16 is engaged with the circular buckle 11. Each second mounting plate... Two springs 13 are fixedly connected to the upper surface of 12, and a limiting block 14 is fixedly connected to the top of each spring 13. Through the above scheme, the main body 2 of the pickup device can be stably installed inside the mounting base 1, and it is convenient to disassemble and maintain it. In use, the elastic force of the spring 13 causes the limiting block 14 to press the first clamping plate 15 and the second clamping plate 16, thereby making the first clamping plate 15 and the second clamping plate 16 tightly engaged with the circular buckle 11, which improves the stability of the installation. When it is necessary to disassemble the main body 2 of the pickup device for maintenance, simply pull down the main body 2 of the pickup device, and then rotate the first clamping plate 15 and the second clamping plate 16 through the pin 18, thereby releasing the fixation of the circular buckle 11. At this time, the connecting plate 9 and the main body 2 of the pickup device can be pulled out from inside the mounting base 1. The operation is convenient and the maintenance efficiency is improved.

[0024] The outer surface of the mounting base 1 has a set of annularly arranged ventilation slots 3. Each ventilation slot 3 has a dustproof mesh fixedly connected to its inner wall. By setting up the ventilation slots 3 and dustproof mesh, heat dissipation can be effectively achieved for the main body 2 of the microphone, preventing overheating due to prolonged operation and ensuring stable operation. Simultaneously, the dustproof mesh prevents dust from entering the mounting base 1, avoiding interference with the operation of the main body 2 and further extending its service life. The inner top wall of the mounting base 1 has symmetrical mounting holes 4, which can accommodate the installation... The mounting base 1, connecting plate 9, and the main body 2 of the pickup device are fixed to prevent them from shaking, which further improves the stability of the installation. A sealing strip 5 is fixedly connected to the upper surface of the connecting plate 9. The outer surface of the sealing strip 5 is in contact with the inner wall of the mounting base 1. By setting the sealing strip 5, the sealing between the connecting plate 9 and the mounting base 1 can be effectively improved, preventing dust and moisture from entering the interior of the mounting base 1 from the gap between the connecting plate 9 and the mounting base 1, which would interfere with the operation of the main body 2 of the pickup device, and further ensuring the stability and service life of the main body 2 of the pickup device.

[0025] A first magnetic block 6 is fixedly connected to the inner top wall of the mounting base 1, and a second magnetic block 7 is fixedly connected to the upper surface of the connecting plate 9. The first magnetic block 6 and the second magnetic block 7 attract each other. Through the cooperation of the first magnetic block 6 and the second magnetic block 7, the connecting plate 9 can be firmly attached to the mounting base 1, which effectively improves the stability and convenience of the connection. In addition, it strengthens the firmness of the connecting plate 9 and the mounting base 1, and improves the stability of the microphone body 2. A set of annularly arranged heat dissipation holes 8 are provided on the upper surface of the connecting plate 9. The heat dissipation holes 8 can effectively dissipate the heat generated by the microphone body 2 during operation, prevent the microphone body 2 from malfunctioning due to overheating, and further improve the stability and service life of the microphone body 2. The mounting base 1 is made of plastic material, which has good insulation performance and corrosion resistance, and can effectively prevent current from interfering with the microphone body 2, while avoiding the corrosion of chemical substances, further ensuring the safety and stability of the microphone body 2.

[0026] The working principle of the utility model is:

[0027] When the main body 2 of the pickup device needs to be inspected, the operator only needs to pull down the main body 2 of the pickup device, which will cause the second clamping plate 16 to rotate the first clamping plate 15 through the pin 18. At this time, the spring 13 will be deformed by force until the first clamping plate 15 and the second clamping plate 16 are disengaged from the circular buckle 11. The main body 2 of the pickup device can then be pulled out from the inside of the mounting base 1 for inspection. The operation is simple and easy to use. At the same time, by setting a dustproof net, dust can be prevented from entering the inside of the mounting base 1 through the ventilation slot 3. By setting a mounting hole 4, it is easy to use bolts to fix the mounting base 1 in a suitable position. By setting a sealing strip 5, the sealing between the connecting plate 9 and the inner wall of the mounting base 1 can be improved. By setting a first magnetic block 6 and a second magnetic block 7, the stability of the connecting plate 9 can be improved, preventing the connecting plate 9 from shaking inside the mounting base 1. By setting a heat dissipation hole 8, the main body 2 of the pickup device can dissipate heat.
