Description

Technical Field

[0001] This utility model relates to the field of audio transmission technology, and in particular to a portable foldable wireless conference stand transmitter. Background Technology

[0002] Portable foldable wireless conference table transmitters play a crucial role in the process of acquiring and stably transmitting conference audio signals. They are used to accurately collect the speaker's voice signal and transmit it wirelessly to the receiving device, thus achieving efficient transmission of conference audio. This ensures that participants can clearly receive the content of the speech and that the conference communication is smooth. Portable foldable wireless conference table transmitters are often used in scenarios such as mobile office meetings, business negotiations, small seminars, and temporary training venues.

[0003] When it is necessary to accurately capture the speaker's voice signal and transmit it wirelessly to the receiving device to achieve efficient transmission of conference audio, a portable foldable wireless conference pedestal transmitter is required. Most existing wireless conference pedestal transmitters are fixed integrated structures, which makes the device too bulky even after storage, making it unsuitable for scenarios requiring portability. To meet basic storage needs, some products use thin-walled plastic materials and simplified folding limiting structures. This requires additional costs to optimize mold precision during production to cover up structural defects, and insufficient material strength directly leads to reduced product quality. Single-axis hinges and weak limiting components are easily damaged after repeated use, reducing the service life to less than half that of normal devices. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable foldable wireless conference stand transmitter, which aims to solve the problems of large storage volume and poor portability of existing wireless conference stand transmitters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable folding wireless conference transmitter, comprising a support rod, a first rotating shaft fixedly connected to the outer wall of the support rod, a first sector gear rotatably connected to the outer wall of the first rotating shaft, a connector rotatably connected to the outer wall of the first rotating shaft, a second sector gear rotatably connected to the outer wall of the connector, a first folding rod fixedly connected to the outer wall of the second sector gear, a first rotating column rotatably connected to the outer wall of the connector, a second folding rod rotatably connected to the outer wall of the first rotating column, a second rotating shaft rotatably connected to the outer walls of both the first and second folding rods, a support plate rotatably connected to the outer walls of multiple second rotating shafts, a rotating base slidably connected to the outer walls of multiple second rotating shafts, and a fixing mechanism rotatably connected to the bottom of the rotating base, the fixing mechanism being used to fix the conference transmitter.

[0006] As a further description of the above technical solution:

[0007] The fixing mechanism includes a support base, the top of which is rotatably connected to the bottom of a rotating base. Multiple outer shells are fixedly connected to the bottom of the support base, and a chassis is fixedly connected to the bottom of each of the multiple outer shells. Sleeves are rotatably connected to the inner walls of each of the multiple outer shells. Multiple guide grooves and locking grooves are provided on the inner walls of the sleeves. Positioning protrusions are slidably connected to the inner walls of the multiple guide grooves, and suction cups are fixedly connected to the outer walls of the positioning protrusions.

[0008] As a further description of the above technical solution:

[0009] A microphone is fixedly connected to the outer wall of the support rod, and a flexible tube is slidably connected to the outer wall of the support rod.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the support base is provided with a storage compartment, and the top of the support base is rotatably connected to multiple second rotating columns.

[0012] As a further description of the above technical solution:

[0013] The outer walls of the plurality of second rotating columns are rotatably connected to cover plates, and the outer walls of the cover plates are slidably connected to the outer walls of the support base.

[0014] As a further description of the above technical solution:

[0015] A magnetic block is fixedly connected to the inner wall of the cover plate, and a handle is fixedly connected to the outer wall of the cover plate.

[0016] As a further description of the above technical solution:

[0017] A display panel is fixedly connected to the top of the support base, and a button is fixedly connected to the top of the support base.

[0018] As a further description of the above technical solution:

[0019] A handle is fixedly connected to the outer wall of the sleeve, and the outer wall of the handle is slidably connected to the outer wall of the outer shell.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when needed, the first and second folding rods are pulled out, and the second rotating shaft is used to rotate the support plate to stand it up. The support plate can also be slidably stretched along the inner wall of the rotating base to detach from the storage compartment to expand the support area and improve the stability of the equipment. When the support rod is rotated, the first rotating shaft on its outer wall provides a rotational basis for the first sector gear and the connector. Through the meshing transmission of the two gears, the angle of the support rod can be flexibly adjusted to meet the needs of different speakers. The connector, through the first rotating column and the second folding rod, forms a double-rod support with the first folding rod. It can both unfold the support plate to a horizontal position for stable support and fold it up to reduce its volume for easy carrying, thereby improving product quality and increasing service life.

[0022] 2. In this utility model, when fixation is required, rotate the handle on the outer wall of the sleeve. The guide groove on the inner wall of the sleeve drives the positioning protrusion to slide, pulling the suction cup upward to tighten and compress. The internal pressure decreases, forming an air pressure difference. When the positioning protrusion slides into the locking groove, the suction cup is fixed in position. The suction force generated by the air pressure difference tightly adheres to the tabletop, achieving stable fixation of the equipment and preventing displacement during meetings. No additional tools are required, and the operation is convenient. When removing, simply rotate the handle in the opposite direction to release the positioning protrusion from the guide groove to unlock. The unlocking process is quick, does not damage the tabletop, and is compatible with various materials of meeting tabletops. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 This utility model provides an embodiment of a portable folding wireless conference transmitter, including a support rod 1. A first rotating shaft 3 is fixedly connected to the outer wall of the support rod 1. A first sector gear 4 is rotatably connected to the outer wall of the first rotating shaft 3. A connector 5 is rotatably connected to the outer wall of the first rotating shaft 3. A second sector gear 6 is rotatably connected to the outer wall of the connector 5. A first folding rod 7 is fixedly connected to the outer wall of the second sector gear 6. A first rotating column 8 is rotatably connected to the outer wall of the connector 5. A second folding rod 9 is rotatably connected to the outer wall of the first rotating column 8. A second rotating shaft 10 is rotatably connected to the outer walls of both the first folding rod 7 and the second folding rod 9. A support plate 11 is rotatably connected to the outer walls of multiple second rotating shafts 10. A rotating base 12 is slidably connected to the outer walls of multiple second rotating shafts 10. A fixing mechanism 2 is rotatably connected to the bottom of the rotating base 12. The fixing mechanism 2 is used to fix the conference transmitter.

[0032] Specifically, the support rod 1 provides support for the microphone 13, and the first rotating shaft 3 on its outer wall provides a rotational base for the first sector gear 4 and the connector 5. Through the meshing transmission of the first sector gear 4 and the second sector gear 6, the first folding rod 7 can be driven to adjust its angle and be folded for storage. The first rotating column 8 on the outer wall of the connector 5 is connected to the second folding rod 9, forming a double-rod support structure with the first folding rod 7. It is rotatably connected to the support plate 11 through the second rotating shaft 10. With the sliding of the rotating base 12 along the second rotating shaft 10, it can be unfolded to a horizontal state and folded for storage. The fixing mechanism 2 can use the suction cup 208 to firmly fix the device on the conference table, ensuring that the device remains stable during multi-angle adjustment and use, and meeting the placement needs of different conference scenarios.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The fixing mechanism 2 includes a support base 201, the top of which is rotatably connected to the bottom of the rotating base 12. Multiple outer shells 202 are fixedly connected to the bottom of the support base 201. A chassis 203 is fixedly connected to the bottom of the multiple outer shells 202. A sleeve 204 is rotatably connected to the inner wall of each of the multiple outer shells 202. Multiple guide grooves 205 and multiple locking grooves 206 are provided on the inner wall of the sleeve 204. Positioning protrusions 207 are slidably connected to the inner wall of the multiple guide grooves 205. A suction cup 208 is fixedly connected to the outer wall of the positioning protrusions 207.

[0034] Specifically, the multiple outer shells 202 at the bottom of the support base 201 provide protection for the internal components, and the bottom of the outer shell 202 is fixed to the chassis 203 to enhance the overall support. The sleeve 204 on the inner wall of the outer shell 202 is rotatable, and the guide groove 205 on its inner wall allows the positioning protrusion 207 to slide. When the sleeve 204 is rotated, the positioning protrusion 207 moves along the guide groove 205, which drives the suction cup 208 to tighten and compress upward to reduce the internal pressure, thereby adsorbing it onto the table. When the positioning protrusion 207 slides into the locking groove 206, the position of the suction cup 208 is fixed. The suction force of the suction cup 208 stabilizes the device on the table and prevents the device from shifting during the meeting.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A microphone 13 is fixedly connected to the outer wall of the support rod 1, a flexible tube 14 is slidably connected to the outer wall of the support rod 1, a cover plate 17 is rotatably connected to the outer wall of a plurality of second rotating columns 16, the outer wall of the cover plate 17 is slidably connected to the outer wall of the support base 201, a storage compartment 15 is opened on the inner wall of the support base 201, and a plurality of second rotating columns 16 are rotatably connected to the top of the support base 201.

[0036] Specifically, the microphone 13 fixed to the outer wall of the support rod 1 can stably pick up audio signals, and the flexible tube 14 sliding on the outer wall protects the internal components and increases the aesthetics. The storage compartment 15 on the inner wall of the support base 201 is used to store the folded microphone 13 for easy carrying. The multiple second rotating columns 16 on its top can drive the cover 17 to rotate, and the cover 17 can slide along the outer wall of the support base 201. When it slides to the closed position, it can cover the storage compartment 15 to achieve dustproof storage of accessories, and when it is opened, it is convenient to take out and put in items.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 A magnetic block 18 is fixedly connected to the inner wall of the cover plate 17, a handle 19 is fixedly connected to the outer wall of the cover plate 17, a throttle 22 is fixedly connected to the outer wall of the sleeve 204, the outer wall of the throttle 22 is slidably connected to the outer wall of the outer shell 202, a display panel 20 is fixedly connected to the top of the support base 201, and a button 21 is fixedly connected to the top of the support base 201.

[0038] Specifically, the magnetic block 18 on the inner wall of the cover plate 17 can be attracted to the support base 201 to enhance the sealing performance of the cover plate 17 when closed. The handle 19 on the outer wall makes it easy to manually pull the cover plate 17, improving the convenience of opening and closing operations. The handle 22 on the outer wall of the sleeve 204 can slide along the outer wall of the outer shell 202. By rotating the handle 22, the sleeve 204 can be easily rotated, which facilitates the adjustment of the suction cup 208. The display panel 20 on the top of the support base 201 can display the device status, and the button 21 is used to control the device switch and mode switching to realize the operation of functions.

[0039] Working principle: When needed, pull out the first folding rod 7 and the second folding rod 9, which are connected to the support plate 11 by the second rotating shaft 10 to stand it up. The support plate 11 can also slide outward along the inner wall of the rotating base 12 to extend it away from the storage compartment 15. Then rotate the support rod 1. The first rotating shaft 3 on its outer wall provides a rotation base for the first sector gear 4 and the connector 5. Through the meshing transmission of the first sector gear 4 and the second sector gear 6, the support rod 1 can be driven to complete the angle adjustment. The first rotating column 8 on the outer wall of the connector 5 is connected to the second folding rod 9, forming a double-rod support structure with the first folding rod 7, which can unfold the support plate 11 to a horizontal state and fold it up.

[0040] When fixation is required, rotate the handle 22 fixed on the outer wall of the sleeve 204. The guide groove 205 on the inner wall of the sleeve 204 will drive the positioning protrusion 207 to slide along the groove, thereby pulling the suction cup 208 upward to tighten and compress. The pressure decreases, forming an internal and external air pressure difference. When the positioning protrusion 207 slides into the locking groove 206, the position of the suction cup 208 is fixed. The suction force generated by the air pressure difference is used to tightly adhere to the tabletop, ultimately achieving stable fixation of the equipment and preventing displacement during the meeting. When removing, simply rotate the handle 22 in the opposite direction to make the positioning protrusion 207 disengage from the guide groove 205 to unlock.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
