Technical Field

[0001] The utility model relates to the technical field of conference microphones, in particular to a flexibly pluggable gooseneck conference microphone. Background Art

[0002] In conference rooms, conference microphones are used to amplify the volume of conference participants during speeches so that many people in the conference room can hear the content of the meeting clearly. Currently, a gooseneck conference microphone is used. Through the setting of the gooseneck hose, the position of the sound head set at one end can be adjusted at will to meet the usage needs of different groups of people.

[0003] However, most existing gooseneck microphones use a metal shaped hose that can be bent and shaped at will as the microphone rod. Although this microphone rod has many adjustable angles, its length is fixed and cannot be adjusted. At the same time, it is relatively laborious to adjust the metal shaped hose, which leads to inflexible use. Utility Model Content

[0004] The purpose of the utility model is to provide a flexibly pluggable gooseneck conference microphone, which has the advantages of being able to conveniently adjust the rotation angle of the microphone and the length of the microphone, thereby solving the problem that the current gooseneck conference microphone is not flexible enough during adjustment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flexibly pluggable gooseneck conference microphone, comprising a microphone base, wherein an adjustment mechanism and a lifting mechanism are arranged on the surface of the microphone base;

[0006] The adjustment mechanism comprises a fixed plate, a support plate and a positioning plate, the inner wall of the fixed plate is slidably connected to a rotating cylinder, a connecting plate is fixed to the surface of the rotating cylinder, a limiting plate is fixed to the surface of the connecting plate, a side plate is fixed to the surface of the support plate, and a first spring is fixed to one side of the positioning plate;

[0007] The lifting mechanism includes a gooseneck tube and a mounting shell, a metal shaping hose is fixed on the surface of the gooseneck tube, a sleeve is fixed on the surface of the metal shaping hose, a movable tube is slidably connected to the inner wall of the sleeve, a microphone assembly is fixed on the surface of the movable tube, a second spring is fixed on the inner wall of the mounting shell, a positioning block is fixed on the surface of the second spring, and a plurality of positioning grooves are provided on the surface of the movable tube.

[0008] As a preferred embodiment of the flexibly pluggable gooseneck conference microphone of the utility model, a surface on one side of the positioning block is arranged in a semicircular structure, and the shape of the positioning groove is adapted to the positioning block.

[0009] As a preferred embodiment of a flexibly pluggable gooseneck conference microphone of the utility model, sliding plates are fixed on both sides of the surface of the movable tube, a sliding groove for cooperating with the sliding plate is provided on the surface of the sleeve, and the sliding plate is slidably connected to the surface of the sliding groove.

[0010] As a preferred embodiment of the flexibly pluggable gooseneck conference microphone of the utility model, a rotating groove is provided on the surface of the rotating cylinder, a blocking plate is fixed on the surface of the fixed plate, and the blocking plate is slidably connected to the surface of the rotating groove.

[0011] As a preferred embodiment of the flexibly pluggable gooseneck conference microphone of the utility model, the left and right surfaces on the top of the limiting plate are chamfered.

[0012] As a preferred embodiment of the flexibly pluggable gooseneck conference microphone of the utility model, the first spring and the second spring are both compression springs.

[0013] As a preferred embodiment of the flexibly pluggable gooseneck conference microphone of the utility model, the surface of the rotating cylinder is provided with friction patterns.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model makes it easier to adjust the rotation angle of the microphone assembly by setting an adjustment mechanism. The rotating cylinder can rotate on the inner wall of the fixed plate. When the rotating cylinder rotates, the connecting plate will drive the limiting plate to rotate together. When the rotating cylinder needs to be rotated, the positioning plate is first pressed to compress the first spring and separate the surface of one side of the positioning plate from between the multiple limiting plates, so that the limiting effect on the rotating cylinder is released and the rotating cylinder can be rotated normally. By directly rotating the rotating cylinder, the rotation angle of the microphone assembly can be adjusted more quickly and at a large angle, so that the operator does not need to frequently move the metal shaping hose.

[0016] 2. The utility model can adjust the extension length of the microphone assembly by setting a lifting mechanism, and the metal shaping hose can be twisted and deformed so that the microphone assembly can be moved to a required position. When the length position of the microphone assembly needs to be adjusted, the movable tube is pulled to slide inside the sleeve. During this process, the positioning block will contact the surface of the movable tube, and it can force itself to move toward the inside of the mounting shell through its own shape, so that the second spring can be compressed. At the same time, when the movable tube moves to the side of the positioning block where the positioning groove is located, the second spring can rebound to allow the positioning block to enter the positioning groove, so that the microphone assembly with adjusted length can obtain a positioning effect, thereby achieving a length adjustment effect on the microphone assembly.

DETAILED DESCRIPTION

[0025] See also Figure 1-7 A flexibly pluggable gooseneck conference microphone comprises a microphone base 1, and an adjustment mechanism 2 and a lifting mechanism 3 are arranged on the surface of the microphone base 1;

[0026] The adjustment mechanism 2 enables the rotation angle of the microphone assembly 305 to be adjusted more easily, and the lifting mechanism 3 enables the extension length of the microphone assembly 305 to be adjusted.

[0027] The adjusting mechanism 2 includes a fixing plate 201, a supporting plate 205 and a positioning plate 207. The fixing plate 201 is arranged on the surface of the microphone base 1. The inner wall of the fixing plate 201 is slidably connected with a rotating cylinder 202. A connecting plate 203 is fixed on the surface of the rotating cylinder 202. A limiting plate 204 is fixed on the surface of the connecting plate 203. The supporting plate 205 is fixed to the surface of the microphone base 1. A side plate 206 is fixed on the surface of the supporting plate 205. A rotating shaft is rotatably connected on the surface of the side plate 206. The surface of the rotating shaft is fixedly connected to the positioning plate 207. A first spring 208 is fixed on one side of the positioning plate 207. One side of the first spring 208 is fixedly connected to the surface of the supporting plate 205. A connecting shell is fixed to the bottom of the rotating cylinder 202. The connecting shell is arranged in a rectangular structure. A connecting seat is rotatably connected inside the microphone base 1. The connecting seat is arranged in a cylindrical structure. A rectangular groove for matching with the connecting shell is provided on the surface of the connecting seat. The connecting shell is located inside the rectangular groove. A threading hole is provided on the surface of the connecting seat.

[0028] The rotating cylinder 202 can rotate on the inner wall of the fixed plate 201. When the rotating cylinder 202 rotates, the connecting plate 203 will drive the limiting plate 204 to rotate together. When the rotating cylinder 202 needs to rotate, the positioning plate 207 is first pressed to compress the first spring 208 and make the surface of one side of the positioning plate 207 separate from the plurality of limiting plates 204, so that the limiting effect on the rotating cylinder 202 is released, so that the rotating cylinder 202 can rotate normally. By directly rotating the rotating cylinder 202, the rotation angle of the microphone assembly 305 can be adjusted more quickly and at a large angle, so that the operator does not need to frequently move the metal shaping hose 302. By setting the rotating cylinder 202 and the microphone base 1, the rotating cylinder 202 can drive the connecting shell to enter the inside of the connecting base, so that the rotating cylinder 202 and the microphone base 1 are connected, and the rotating cylinder 202 can normally drive the connecting shell to rotate inside the connecting base, and the rotating cylinder 202 can also drive the fixed plate 201 to be disassembled from the microphone base 1.

[0029] The lifting mechanism 3 includes a gooseneck tube 301 and a mounting shell 306. The gooseneck tube 301 is fixed to the surface of the rotating cylinder 202. A metal shaping hose 302 is fixed to the surface of the gooseneck tube 301. A sleeve 303 is fixed to the surface of the metal shaping hose 302. A movable tube 304 is slidably connected to the inner wall of the sleeve 303. A microphone assembly 305 is fixed to the surface of the movable tube 304. The line on the surface of the microphone assembly 305 passes through the movable tube 304, the sleeve 303, the metal shaping hose 302, the gooseneck tube 301 and the interior of the rotating cylinder 202 and is connected to the microphone base 1. The mounting shell 306 is fixed to the surface of the sleeve 303. The surface of the sleeve 303 is connected to the mounting shell 306. A second spring 307 is fixed to the inner wall of the mounting shell 306. A positioning block 308 is fixed to the surface of the second spring 307. A plurality of positioning grooves 309 are provided on the surface of the movable tube 304.

[0030] The metal shaping hose 302 can be twisted and deformed so that the microphone assembly 305 can be moved to the required position. When the length position of the microphone assembly 305 needs to be adjusted, the movable tube 304 is pulled to make the movable tube 304 slide inside the sleeve 303. During this process, the positioning block 308 will contact the surface of the movable tube 304, and it can force itself to move toward the inside of the mounting shell 306 through its own shape, so that the second spring 307 can be compressed. At the same time, when the movable tube 304 moves to the side of the positioning groove 309 located on the positioning block 308, the second spring 307 can rebound to make the positioning block 308 enter the positioning groove 309, so that the microphone assembly 305 with the adjusted length can obtain the positioning effect, thereby achieving the length adjustment effect of the microphone assembly 305.

[0031] Furthermore, one side surface of the positioning block 308 is provided with a semicircular structure, and the shape of the positioning groove 309 is adapted to the positioning block 308;

[0032] The shape of the positioning block 308 is set to ensure that when its semicircular surface contacts the movable tube 304 , the positioning block 308 can move normally toward the inside of the mounting shell 306 , and the positioning block 308 can also be separated from the positioning groove 309 .

[0033] Furthermore, sliding plates 310 are fixed on both sides of the surface of the movable tube 304, and a sliding groove for matching with the sliding plates 310 is provided on the surface of the sleeve 303, and the sliding plates 310 are slidably connected with the surface of the sliding groove;

[0034] When the movable tube 304 slides on the inner wall of the sleeve 303, the sliding plate 310 will slide on the surface of the slide groove, so that the movable tube 304 has a guiding effect and the movable tube 304 will not rotate.

[0035] Furthermore, a rotating groove is formed on the surface of the rotating cylinder 202, and a blocking plate 209 is fixed on the surface of the fixed plate 201, and the blocking plate 209 is slidably connected to the surface of the rotating groove;

[0036] When the rotating cylinder 202 rotates, the blocking plate 209 can slide in the rotating groove, thereby preventing the rotating cylinder 202 from separating from the fixing plate 201 .

[0037] Furthermore, the left and right surfaces of the top of the limiting plate 204 are chamfered;

[0038] By setting the top of the limiting plate 204, when the edge of the surface of the positioning plate 207 contacts the chamfer of the top of the limiting plate 204, the limiting plate 204 can force the rotating cylinder 202 to rotate through its own chamfer and the surface of the positioning plate 207, so that the positioning plate 207 can more easily enter between multiple limiting plates 204.

[0039] Further, the first spring 208 and the second spring 307 are both compression springs;

[0040] By disposing the first spring 208 and the second spring 307 , it is ensured that the positioning plate 207 can rotate normally, and the positioning block 308 can move toward the movable tube 304 normally.

[0041] Furthermore, friction lines are provided on the surface of the rotating cylinder 202;

[0042] The friction pattern is provided to make it easier for operators to rotate the rotating drum 202 .

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
