Technical Field

[0001] This utility model relates to the field of microphone stand technology, and more specifically, to a microphone stand fixing structure. Background Technology

[0002] In professional settings such as broadcast and television recording, live performances, and conference speeches, the height adjustment function of the microphone stand is a key factor in meeting the needs of different users.

[0003] Most microphone stand fixing structures on the market currently adopt screw locking or snap-on designs, which have obvious operational inconvenience problems in actual use. Users need to rotate the screws multiple times or repeatedly adjust the position of the snap-on to achieve a precise height setting. This cumbersome adjustment process is not only time-consuming and laborious, but also cannot meet the needs of quick switching on site. Especially in the case of multiple people taking turns using the microphone or in compact performance scenarios, the inefficiency of traditional fixing structures often leads to the interruption of the program flow, affecting the overall performance quality and professional image, and cannot meet the high requirements of the modern media industry for equipment flexibility and ease of operation.

[0006] The present invention is further provided with a guide bar fixedly provided on the outer wall of the lifting rod. The guide bar is provided in multiple sets and is slidably connected to the sleeve. With this design, the lifting rod can be lifted and lowered more smoothly, reducing friction and improving the stability and durability of the overall structure.

[0007] The present invention is further provided that the outer sides of the multiple sets of adjustment holes and insertion holes are provided with rounded corners. The rounded corner design makes the insertion process smoother, avoids jamming, and increases the stability and operating comfort during assembly.

[0008] The present invention is further configured such that push springs are connected between the inner sides of multiple sets of card blocks and the movable grooves, and multiple sets of push springs are provided. The arrangement of push springs ensures a stable connection between the card blocks and the movable grooves, thereby enhancing the tightness and reliability of the assembled structure.

[0009] The present invention is further configured such that the outer wall of the fixed sleeve is provided with a sliding groove, and multiple sets of sliding grooves are provided, each of which is slidably connected to a sliding sleeve. An unlocking sleeve is fixedly provided on the inner side of the sliding sleeve. This design can ensure smoother unlocking operation, reduce jamming and resistance during operation, and improve disassembly efficiency.

[0010] The present invention is further configured such that a sliding rod is fixedly provided on the outer wall of the fixed sleeve, and multiple sets of sliding rods are provided, all of which are slidably connected to the sliding sleeve. The slidable connection between the sliding rod and the sliding sleeve makes the adjustment of the fixed sleeve more flexible, thereby improving the overall operation performance and flexibility of the device.

[0011] The present invention is further provided with a return spring on the outer side of each of the multiple sets of slide rods. The two ends of the multiple sets of return springs are respectively connected to the slide sleeve and the fixed sleeve. The return springs can automatically reset after operation, ensuring that the structure returns to the initial state and avoiding jamming or misalignment caused by excessive operation.

[0012] The present invention is further configured such that a connecting ring is abutted at the bottom end of the fixed sleeve, and a compression spring is connected between the connecting ring and the outer wall of the fixed sleeve. The connecting ring abuts against the outer wall of the sleeve. The design of the connecting ring and the compression spring can provide additional support and elastic force, enhance the stability and durability of the entire device, and improve the convenience of disassembly and assembly.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a microphone holder fixing structure, which has the following beneficial effects: 1. This microphone stand fixing structure cleverly solves the technical problem of inconvenient height adjustment of traditional microphone stands through an innovative combination design of plug rod and fixing sleeve. The operator only needs to insert the plug rod into the aligned adjustment hole and plug hole, and then insert the fixing sleeve into the top of the plug rod. Multiple sets of locking blocks automatically slide out of the movable groove under the action of the push spring and abut against the locking ring to form a lock. The entire fixing process is simple and quick and does not require any tools. This one-step locking mechanism significantly improves the efficiency and convenience of height adjustment. It is especially suitable for professional occasions such as broadcast and television recording and live performances that require frequent adjustment of equipment height, perfectly meeting the strict requirements of modern media industry for equipment operation flexibility and response speed.

[0014] 2. The unlocking mechanism of this device is also ingeniously designed. By pushing the sliding sleeve to slide along the sliding rod and the sliding groove, the unlocking sleeve abuts against the locking block and retracts into the movable groove. At the same time, the elastic force of the compression spring automatically pushes the fixed sleeve to separate from the insertion rod and pops the insertion rod out of the hole, realizing a one-button quick unlocking function. This design not only greatly reduces the time and complexity of unlocking operations, but also maintains stable and reliable performance even in changing environments such as outdoor interviews or mobile recording. Users no longer need to compromise between stability and ease of operation, providing an ideal support tool for professional recording work.

[0015] 3. This microphone stand fixing structure also integrates several refined structural optimization designs. Multiple guide bars ensure the smooth operation of the lifting rod during adjustment without deflection. The rounded corners on the outside of the adjustment hole and the socket reduce resistance and wear when inserting the rod. The cooperation of multiple sliding rods and return springs ensures that the sliding sleeve can automatically return to its position after unlocking, ready for the next operation. The setting of the connecting ring and compression spring cleverly solves the problem of excessive pulling force when pulling out the fixing sleeve. These seemingly small but carefully considered design details together create a microphone stand fixing system that is both easy to operate and robust and durable, greatly improving the user experience and work efficiency of the product, and providing more reliable and user-friendly equipment support for various professional audio recording scenarios.
