[0002] A network audio transmitter is a device used to transmit audio signals over a network. It can transmit audio data from the sender to the receiver to achieve remote audio transmission and real-time audio communication. When using a network audio transmitter, it is usually necessary to use an audio cable and a network cable to connect the network transmission device to the audio source or sound system. This connection method can transmit audio signals through audio cables and communicate with the network through network cables to achieve high-quality audio transmission and playback.

[0003] When using existing network audio transmitters, due to the diversity of the audio transmitter's connecting line interfaces, there are various types of plugs and interfaces, the plugs cannot be fixed, and the connecting lines are easily accidentally touched and fall off. When the connecting lines are loose, the audio transmission will be interrupted or noise will occur, affecting the audio quality and listening experience. Therefore, we propose a new type of network audio control and transmission device. Utility Model Content

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1 - 5 shown, the present invention provides a network audio control and transmission device, including a bottom plate 1. A positioning pin 12 is fixedly installed at a position near the left side of the top of the bottom plate 1. Fixed blocks 3 are symmetrically and fixedly installed on the left surface of the positioning pin 12. Guide grooves 31 are opened on the inner bottom and inner top of the fixed blocks 3. An insertion plate 33 is slidably arranged between the inner walls of the two guide grooves 31. A ratchet pawl 34 is fixedly connected to the outer surface of one side of the insertion plate 33. A pressing block 35 is fixedly connected to the outer surface of one side of the ratchet pawl 34. Ratchet teeth 32 are fixedly connected to the positions near the edges of the inner bottom and inner top of the fixed blocks 3. The tooth surface of the ratchet teeth 32 cooperates with the ratchet pawl 34. A clamping plate 36 is fixedly connected to the outer surface of the other side of the fixed block 3 near the edge. A card slot 37 is penetrated through the outer surface of the clamping plate 36. A sliding groove 13 is opened on the right surface of the positioning pin 12. A bidirectional threaded rod 14 is arranged inside the sliding groove 13. The top end of the bidirectional threaded rod 14 movably penetrates through the inner top of the sliding groove 13 and extends upward. A knob 15 is fixedly connected to the top end of the bidirectional threaded rod 14. Slide blocks 16 are symmetrically and threadedly connected to the outer surface of the bidirectional threaded rod 14. The slide blocks 16 are slidably arranged inside the sliding groove 13. A clamping plate 17 is fixedly installed on the outer surface of the right side of the slide block 16. The input end of the audio transmitter 2 is plugged with a network cable 21, and the output end of the audio transmitter 2 is plugged with an audio cable 22.

[0024] The effect achieved by the entire Embodiment 1 is that by manually rotating the knob 15, the bidirectional threaded rod 14 is driven to rotate. When the bidirectional threaded rod 14 rotates, the two sliders 16 are driven to approach each other. Cooperating with the two clamping plates 17, the audio transmitter 2 can be clamped and fixed. Through the card slots 37 on the corresponding card plate 36, the network cable 21 and the audio cable 22 are respectively sleeved inside the corresponding card slots 37. By inserting the plug board 33 into the fixed block 3 along the guiding groove 31 in the fixed block 3, at this time, the inclined surface of the pawl 34 will cooperate with the tooth surface of the ratchet tooth 32. Since the pawl 34 has a certain toughness, it can undergo slight deformation under the extrusion of the tooth surface of the ratchet tooth 32. Thus, when the pawl 34 moves, it can be engaged with the ratchet tooth 32 to play a role in limiting the plug board 33. When the surface of the card plate 36 contacts the joint position of the network cable 21 or the audio cable 22, due to the relatively large joint position, cooperating with the card slot 37, the interface can be pressed onto the audio transmitter 2, making the joint not easily pulled out, that is, it plays a role in fixing the joint and effectively avoids loosening. When it is necessary to remove the network cable 21 or the audio cable 22, by manually pressing the pressing block 35, the pawl 34 is separated from the ratchet tooth 32, and then the plug board 33 is pulled out from the fixed block 3, so that the card plate 36 can be removed, and the network cable 21 or the audio cable 22 can be taken out.

[0025] Embodiment 2 is as Figures 1 - 5 shown. A protective cover 4 is arranged at the position near the right edge of the top of the bottom plate 1. A pin hole 41 is opened at the bottom of the protective cover 4. The side plates 11 are symmetrically and fixedly connected to the position near the right side of the top of the bottom plate 1, and the outer surface of the side plate 11 cooperates with the inner wall of the pin hole 41.

[0026] The effect achieved by the entire Embodiment 2 is that through the cooperation of the pin hole 41 on the protective cover 4 and the side plate 11 on the bottom plate 1, the protective cover 4 is directly installed on the top of the bottom plate 1, thus playing a role in protecting the audio transmitter 2 and avoiding damage to the audio transmitter 2 caused by external force bumps, effectively improving safety.

[0027] Working principle: When in use, first insert the network cable 21 and the audio cable 22 into the audio transmitter 2 in sequence, and connect the other ends of the network cable 21 and the audio cable 22 to the network transmission device and the audio system respectively. Then, place the audio transmitter 2 between the two clamping plates 17, and manually rotate the knob 15 to drive the bidirectional threaded rod 14 to rotate. When the bidirectional threaded rod 14 rotates, it drives the two sliders 16 to approach each other, and cooperates with the two clamping plates 17 to clamp and fix the audio transmitter 2. Then, through the card slots 37 on the corresponding card plate 36, the network cable 21 and the audio cable 22 are respectively sleeved inside the corresponding card slots 37. Subsequently, insert the plug board 33 along the guiding groove 31 in the fixing block 3 into the inside of the fixing block 3. At this time, the inclined surface of the pawl 34 will cooperate with the tooth surface of the ratchet tooth 32. Due to the certain toughness of the pawl 34, it can undergo slight deformation under the extrusion of the tooth surface of the ratchet tooth 32, so that the pawl 34 can be engaged with the ratchet tooth 32 during the movement process, playing a role in limiting the plug board 33. When the surface of the card plate 36 contacts the joint position of the network cable 21 or the audio cable 22, due to the relatively large joint position, it cooperates with the card slot 37 to press the interface on the audio transmitter 2, making the joint not easily pulled out, that is, playing a role in fixing the joint, effectively avoiding loosening. Finally, through the pin hole 41 on the shield 4 and the side plate 11 on the bottom plate 1, directly install the shield 4 on the top of the bottom plate 1, thus playing a role in protecting the audio transmitter 2 and preventing it from being damaged due to external collision, effectively improving the safety. When it is necessary to remove the network cable 21 or the audio cable 22, manually press the pressing block 35 to separate the pawl 34 from the ratchet tooth 32, and then pull out the plug board 33 from the fixing block 3, so that the card plate 36 can be removed, and the network cable 21 or the audio cable 22 can be taken off.

[0028] The above is only the preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
