Description

Technical Field

[0001] The utility model relates to the technical field of conference microphones, in particular to a conference microphone with a protection function. Background Technique

[0002] Conference microphones are important tools for speaking and communicating in conference settings. The quality of their performance directly affects the efficiency and atmosphere of the conference. Most traditional conference microphones adopt a fixed base design. Although the structure is simple, there are certain limitations in actual use. Usually, the conference microphone is directly placed on the table, and the bottom end of the microphone is connected by a long wire. Moreover, the center of gravity of the conference microphone is relatively high, and the stability is poor, resulting in poor protection effect. If a person's foot pulls the wire when walking, it will quickly cause the entire conference microphone to fall. And after the conference microphone is placed, when the table is impacted, due to its high center of gravity, it is extremely easy to fall on the table. Therefore, the stability of the conference microphone base directly affects the protection performance of the conference microphone. Improving the stability of the installation structure of the conference microphone base helps to improve its protection performance.

[0003] However, when the existing conference microphones are fixedly installed, it is often difficult to adapt to table boards of different widths, resulting in insufficient stability of the microphone and easy displacement during use, affecting the speaking effect. In addition, when the distance between the base and the wall is relatively close, the installation and adjustment space of the microphone is limited and the operation is inconvenient. These problems need to be solved urgently. For this reason, a conference microphone with a protection function is needed to solve the existing deficiencies. Summary of the Utility Model

The clamping plate 6 is located at the bottom end of the base 1. An adjusting mechanism 7 is arranged inside the receiving block 4, and the adjusting mechanism 7 is connected to the reset mechanism 5.

[0026] As Figure 1 、 Figure 3 and Figure 4 shown, the reset mechanism 5 includes a connecting plate 501, connecting rods 502 and a reset spring 503. The connecting rods 502 and the reset spring 503 are both symmetrically arranged. The top ends of the connecting rods 502 are fixedly connected to the bottom end of the connecting plate 501. The connecting rods 502 all penetrate through the receiving block 4, and the connecting rods 502 are movably connected to the receiving block 4. The reset springs 503 are respectively sleeved on the outside of the connecting rods 502. The top end of the reset spring 503 is fixedly connected to the bottom end of the connecting plate 501. The bottom end of the reset spring 503 is fixedly connected to the top end of the receiving block 4. The bottom ends of the connecting rods 502 are fixedly connected to the top end of the clamping plate 6. The side of the connecting plate 501 is movably connected to the outside of the sleeve 3. A plurality of anti-slip stickers 8 are fixedly connected to the top end of the clamping plate 6, and a plurality of anti-slip stickers 8 are fixedly connected to the bottom end of the base 1.

[0027] Pull the clamping plate 6 downward to separate it from the base 1, drive the connecting rods 502 to move downward, drive the connecting plate 501 to move downward along the sleeve 3, so that the reset spring 503 is compressed and shortened, thereby increasing the distance between the clamping plate 6 and the base 1, so as to facilitate appropriate adjustment according to the width of the table board, and it is beneficial to use the reset spring 503 to increase the clamping tightness among the base 1, the clamping plate 6 and the table board.

[0028] As Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the adjusting mechanism 7 includes a moving plate 701, insertion blocks 702, adjusting rods 703 and compression springs 704. The insertion blocks 702 are symmetrically arranged and are fixedly connected to the same side of the moving plate 701. The adjusting rods 703 penetrate through the center of the moving plate 701 and are fixedly connected to the moving plate 701. The compression springs 704 are sleeved on the outer sides of the adjusting rods 703. The moving plate 701 is movably connected to the inside of the receiving block 4. One end of the compression spring 704 is fixedly connected to the moving plate 701, and the other end of the compression spring 704 is fixedly connected to the inside of the receiving block 4. Several teeth 9 are longitudinally formed on the outer side of the connecting rod 502, and the inclined surfaces of the teeth 9 face the bottom end of the base 1. The inclined surfaces of the insertion blocks 702 face the top end of the base 1. The inclined surfaces of the teeth 9 are fitted with the inclined surfaces of the insertion blocks 702. Several tooth blocks 10 are fixedly connected to the inside of the base 1 and are distributed in a circular array. One end of the adjusting rod 703 is fixedly connected with a limiting block 11, and the limiting block 11 is engaged with the tooth block 10. The other end of the adjusting rod 703 is fixedly connected with an adjusting knob 12, and the adjusting knob 12 is located outside the receiving block 4.

[0029] By means of the adjusting knob 12, it is convenient to control the movement of the moving plate 701 and the adjusting rod 703, so as to effectively control the engagement or separation of the insertion blocks 702 and the teeth 9. Thus, it is convenient to control whether the connecting rod 502 can be reset under the action of the return spring 503, which is beneficial to controlling the engagement or separation of the limiting block 11 and the tooth block 10, convenient for adjusting the position of the receiving block 4, and beneficial to fixing the position of the base 1 according to the actual use scenario.

[0030] Working principle: When in use, first, pull the chuck 6 downward to separate it from the base 1, drive the connecting rod 502 to move downward, drive the connecting plate 501 to move downward along the housing 3, so that the return spring 503 is compressed and shortened. The inclined surface of the tooth 9 on the side of the connecting rod 502 abuts against the inclined surface of the insertion block 702, thereby pushing the insertion block 702 away from the connecting rod 502, so that the moving plate 701 and the adjusting rod 703 move synchronously. Under the action of the compression spring 704, the insertion block 702 engages with the next tooth 9, so that the connecting rod 502 can only move downward unidirectionally and cannot move upward. Subsequently, the tabletop is clamped on the opposite sides of the base 1 and the chuck 6, so that the anti-slip sticker 8 is attached to the tabletop surface. Then, pull the adjusting knob 12 outward. Under the action of the adjusting rod 703 and the moving plate 701, the insertion block 702 is separated from the tooth 9 of the connecting rod 502. Under the action of the return spring 503, drive the chuck 6 to move close to the bottom end of the base 1, thereby increasing the tightness between the chuck 6 and the base 1; in addition, the placement position of the base 1 is likely to conflict with the wall. Then, pull the adjusting knob 12 outward, drive the adjusting rod 703 and the limiting block 11 to move outward, so that the limiting block 11 is separated from the tooth block 10. Then, the housing 3 can be rotated, so as to change the position where the receiving block 4 is located, which is convenient for the fixed installation of the base 1.
