Technical Field

[0001] The utility model relates to the technical field of hanging microphone sound amplification devices, in particular to a hanging microphone sound amplification device used in a stepped classroom. Background Art

[0002] The hanging microphone is generally fixed to a fixed position on the ceiling by a hanging microphone bracket. The hanging microphone is usually used for teaching sound reinforcement. The original intention is to free the hands to facilitate teachers to teach easily and for the sake of teachers' health. Therefore, the hanging microphone sound reinforcement device is more effective when used in a stepped classroom. At the same time, the internal space of the stepped classroom is larger, so the hanging microphone sound reinforcement device can be more convenient when used.

[0003] In the prior art, most of the microphone-hanging sound reinforcement devices are installed and fixed on the top of the wall by multiple bolts.

[0004] However, since a lot of dust will accumulate when it is set in a fixed position for a long time, the hanging microphone sound reinforcement device needs to be disassembled and maintained regularly when it is in use. The usual hanging microphone sound reinforcement device requires the removal of multiple bolts during installation and disassembly, which makes the hanging microphone sound reinforcement device inconvenient to disassemble and maintain. Utility Model Content

[0005] The purpose of the utility model is to provide a microphone-hanging sound amplification device for a lecture hall to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a hanging microphone sound amplification device for a stepped classroom, comprising a mounting plate, a locking bolt, a mounting frame and a hanging microphone sound amplifier, the bottom of the mounting plate is connected with a locking bolt, a mounting frame is arranged below the mounting plate, and the bottom of the mounting frame is arranged with a hanging microphone sound amplifier.

[0007] Preferably, a stabilizing seat is provided on a side of the mounting frame away from the mounting plate, a first threaded rod is provided inside the stabilizing seat, and a rotating hand wheel is connected to one side of the first threaded rod.

[0008] Preferably, a displacement block is connected to the surface of the rotating hand wheel, a locking block is arranged on the surface of the displacement block, a displacement rod is arranged on the side of the stabilizing seat close to the first threaded rod, and a limiting spring is connected to one side of the displacement rod.

[0009] Preferably, a mounting block is disposed inside the mounting frame, an adjusting block is disposed below the mounting block, and a driving motor is disposed inside the adjusting block.

[0010] Preferably, the output end of the driving motor is connected to a second threaded rod.

[0011] Preferably, a moving block is connected to the surface of the second threaded rod, a displacement plate is connected to the surface of the moving block, and a connecting rod is connected to one side of the displacement plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model discloses a hanging microphone sound amplification device for a tiered classroom. When the hanging microphone sound amplification device is used in the tiered classroom, it is usually not easy to disassemble and maintain it. By rotating the rotating hand wheel, the rotating hand wheel can rotate the connected first threaded rod when rotating, so that the first threaded rod can move the locking block through the connected displacement block when rotating, so that the locking block can squeeze and push the displacement rod when moving, so that the displacement rod can be separated from the installation frame when it is displaced, thereby making it more convenient to disassemble and maintain the hanging microphone sound amplification device when used in the tiered classroom.
