Technical Field

[0001] The present application relates to the field of microphones, and in particular to a ceiling microphone stand. Background Art

[0002] A microphone, also known as a microphone or micro-phone, is an energy conversion device that converts sound signals into electrical signals. Microphones are categorized into dynamic, condenser, electret, and the more recently emerging silicon micro-microphones. Liquid and laser microphones are also available. Ceiling microphones are primarily used in medium-sized conference rooms, classrooms, and collaborative spaces.

[0003] Existing ceiling microphone stands are generally fixed with a large number of bolts during installation, which makes it difficult to disassemble the microphone when it needs to be replaced after installation, resulting in reduced work efficiency. Utility Model Content

[0007] By adopting the above technical solution, when in use, the microphone body is slid into the installation frame through the sliding groove and the sliding bar, and then the baffle is placed at the opening of the installation frame. The two-way threaded rod is rotated by the transmission mechanism, and the limit assembly is used to prevent the plug-in sleeve from rotating with it, so that the plug-in sleeve moves at both ends of the two-way threaded rod, moves the plug-in sleeve out of the through hole, and plugs it into the jack, and fixes the baffle on the installation frame to prevent the microphone body from sliding out. When disassembling, it is only necessary to rotate the two-way threaded rod in the opposite direction to disengage the plug-in sleeve from the jack, thereby avoiding as much as possible the problem of difficulty in disassembly when the microphone needs to be replaced after installation, which reduces work efficiency.

[0008] Preferably, the transmission mechanism includes a first bevel gear fixedly connected to the bidirectional threaded rod, a rotating shaft is provided at the bottom end of the baffle, one end of the rotating shaft passes through the baffle and is fixedly connected to a second bevel gear, and the second bevel gear is meshed with the first bevel gear.

[0012] Preferably, a square hole is formed at one end of the rotating shaft away from the second bevel gear, a square block is inserted into the square hole, and one end of the square block away from the square hole is fixedly connected to a rotating disk.

[0013] By adopting the above technical solution, when rotating the rotating shaft, the square block is inserted into the square hole to connect the rotating disk with the rotating shaft, which facilitates the rotation of the rotating shaft. At the same time, after the rotation is completed, the rotating disk is removed, which can reduce the rotation of the rotating shaft during use.

[0014] Preferably, a limiting rod is fixedly connected in the limiting groove, and the limiting blocks are respectively sleeved on the limiting rod.

[0015] By adopting the above technical solution, the stability of the limiting block moving in the limiting groove can be improved through the limiting rod, thereby improving the stability of the plug-in sleeve.

[0020] Preferably, a slot is provided at the top of one end of the connector sleeve away from the fixing block, and a card plate is provided in the slot.

[0021] By adopting the above technical solution, after the plug sleeve is inserted into the socket, the card plate is inserted into the card slot, which can prevent the two-way threaded rod from rotating during use and causing the plug sleeve to be separated from the socket.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The present application adopts the coordination arrangement between the baffle, the bidirectional threaded rod and the plug-in sleeve. When in use, the microphone body is slid into the installation frame through the sliding groove and the sliding bar, and then the baffle is placed at the opening of the installation frame. The bidirectional threaded rod is rotated by the transmission mechanism, and the plug-in sleeve is prevented from rotating with it by the limit assembly. The plug-in sleeve is moved at both ends of the bidirectional threaded rod, and the plug-in sleeve is moved out of the through hole and plugged into the socket. The baffle is fixed to the installation frame, so that the microphone body cannot slide out. When disassembling, it is only necessary to rotate the bidirectional threaded rod in the opposite direction to disengage the plug-in sleeve from the socket. This avoids the problem of difficulty in disassembly when the microphone needs to be replaced after installation, which reduces work efficiency.

[0034] There are two jacks 5, which are respectively opened on the side walls on both sides of the opening of the mounting frame 1. A baffle 6 is set at the opening of the mounting frame 1 to prevent the microphone body 2 from sliding out of the opening of the mounting frame 1. A through hole 7 is opened in the baffle 6 and the through opening is located at both ends of the baffle 6. There are two fixing blocks 8 and they are fixedly connected in the through hole 7. There is a spacing between the two fixing blocks 8. A bidirectional threaded rod 9 is set in the through hole 7. The bidirectional threaded rod 9 passes through the two fixing blocks 8 and forms a rotation connection. Both ends of the bidirectional threaded rod 9 are threadedly connected with a plug-in sleeve 10. The end of the plug-in sleeve 10 away from the bidirectional threaded rod 9 is respectively plugged into the jack 5 to fix the baffle 6 at the opening of the mounting frame 1. The bidirectional threaded rod 9 and the baffle 6 are provided with a transmission mechanism for driving the bidirectional threaded rod 9 to rotate, and the plug-in sleeve 10 is provided with a limit assembly for preventing the plug-in sleeve 10 from rotating.

[0035] Reference Figure 3 The transmission mechanism includes a first bevel gear 11 fixedly connected to the bidirectional threaded rod 9, a rotating shaft 12 is provided at the bottom end of the baffle 6, one end of the rotating shaft 12 passes through the baffle 6 and is fixedly connected to a second bevel gear 13, the second bevel gear 13 is engaged with the first bevel gear 11, and the second bevel gear 13 is rotated by rotating the rotating shaft 12 forward and backward, driving the first bevel gear 11 to rotate, so that the bidirectional threaded rod 9 rotates forward and backward.

[0036] Reference Figure 3 The limit assembly includes limit blocks 14 fixedly connected to both sides of the plug sleeve 10 near one end of the fixed block 8. The side walls of the through hole 7 are located at the limit blocks 14 and limit grooves 15. The limit blocks 14 are slidably arranged in the limit grooves 15 respectively. The limit blocks 14 and the limit grooves 15 can prevent the bidirectional threaded rod 9 from rotating and driving the plug sleeve 10 to rotate together, resulting in the plug sleeve 10 being unable to move back and forth on the bidirectional threaded rod 9.

[0037] Reference Figure 3 and Figure 4 A square hole 16 is provided at the end of the rotating shaft 12 away from the second bevel gear 13, and a square block 17 is inserted into the square hole 16. The end of the square block 17 away from the square hole 16 is fixedly connected to a rotating disk 18. When the rotating shaft 12 is rotated, the square block 17 is inserted into the square hole 16 to connect the rotating disk 18 to the rotating shaft 12, which facilitates the rotation of the rotating shaft 12.

[0040] Reference Figure 1 A fixing box 22 is provided on the upper surface of the mounting frame 1, and an electric telescopic rod 23 is fixedly connected to the fixing box 22. The output end of the electric telescopic rod 23 passes through the top of the fixing box 22 and is fixedly connected to a connecting frame 24. The four ends of the lower surface of the connecting frame 24 are fixedly connected to the four ends of the upper surface of the mounting frame 1. The fixing box 22 is fixed under the ceiling. By starting the electric telescopic rod 23, the connecting frame 24 can be driven to rise and fall to adjust the height of the microphone body 2.

[0041] Reference Figure 5 A card slot 25 is provided at the top of the end of the plug sleeve 10 away from the fixed block 8, and a card plate 26 is provided in the card slot 25. By inserting the plug sleeve 10 into the socket 5 and then inserting the card plate 26 into the card slot 25, the bidirectional threaded rod 9 can be prevented from rotating during use, thereby disengaging the plug sleeve 10 from the socket 5.

[0042] The implementation principle of the ceiling microphone bracket of the embodiment of the present application is as follows: when in use, the microphone body 2 is slid into the installation frame 1 through the slide groove 4 and the slide bar 3, and then the baffle 6 is placed at the opening of the installation frame 1, and the rotating disk 18 is connected to the rotating shaft 12 by inserting the square block 17 into the square hole 16 to rotate the rotating shaft 12, so that the second bevel gear 13 drives the first bevel gear 11 to rotate, so that the bidirectional threaded rod 9 rotates. At the same time, the limit block 14 and the limit groove 15 prevent the plug-in sleeve 10 from rotating with the bidirectional threaded rod 9, so that the plug-in sleeve 10 moves at both ends of the bidirectional threaded rod 9, moves the plug-in sleeve 10 out of the through hole 7, and plugs it into the socket 5, fixes the baffle 6 on the installation frame 1, so that the microphone body 2 cannot slide out. When disassembling, you only need to repeat the above operation and rotate the rotating disk 18 in the opposite direction to disengage the plug-in sleeve 10 from the socket 5, so as to avoid the problem of difficulty in disassembly when the microphone needs to be replaced after installation, which reduces the work efficiency.
