Description

A microphone lift structure Technical Field

[0001] This utility model relates to the field of microphone lifting technology, specifically to a microphone lifting device structure. Background Technology

[0002] The existing microphones cannot be raised and lowered freely. When adjusting the height, it is necessary to loosen the locking mechanism, then adjust the height, and then tighten the locking mechanism again. This operation is quite cumbersome. In scenarios such as on stage, KTV, and TV station, the height of the microphone changes constantly with people of different heights. If the locking mechanism is frequently adjusted, it will inevitably waste a lot of time.

[0003] For example, CN209897227U discloses a freely height-adjustable microphone, including a support base and a microphone. A hollow sleeve is installed on the top of the support base, and a constant-force spring is installed on the inner top of the hollow sleeve. A lifting rod is provided on the top of the constant-force spring, and a hinge seat is threaded onto the upper end of the lifting rod. A microphone bracket is hinged to the top of the hinge seat, and the microphone is placed on the microphone bracket. This invention allows for the application of a downward or upward force, such as pressing down or lifting up, to break the balance, thus lowering or raising the lifting rod. After the external force is removed, the constant-force spring returns to equilibrium, preventing further lifting or lowering, thereby stabilizing the microphone. It is user-friendly, has a reasonable structure, ingenious design, is easy to use, allows for convenient height adjustment, saves time, and is suitable for widespread use.

[0004] However, in implementing the relevant technology, the above-mentioned freely height-adjustable microphone has the following problems: it is difficult to fix the microphone after the height adjustment is completed, which makes it easy for the microphone to fall downwards during use, thereby reducing the stability of the microphone. Therefore, a microphone lifting device structure is proposed. Summary of the Invention

[0005] This invention proposes a microphone lifter structure, which solves the problem in related technologies where fixing the microphone after lift adjustment can easily cause the microphone to fall downwards during use, thereby reducing the stability of the microphone.

[0006] The technical solution of this utility model is as follows: a microphone lifter structure, comprising: a fixed base and a microphone;

[0007] A lifting mechanism, located on top of the fixed base, is used for adjusting the height of the microphone.

[0008] A locking mechanism is provided inside the lifting mechanism to lock the position of the microphone after the lifting mechanism has been adjusted.

[0009] An adjustment mechanism, located on top of the locking mechanism, is used for tilting and adjusting the microphone forward and backward.

[0010] The bottom of the fixed base is fixedly installed with a circular rubber anti-slip pad and a plurality of suction cups, and the plurality of suction cups are arranged in a circular array around the circular rubber anti-slip pad.

[0011] Preferably, the lifting mechanism includes a sealing cylinder fixedly installed on the top of the fixed base, a slide rod slidably passing through the top of the sealing cylinder, and a mounting block fixedly connected to the bottom end of the slide rod, wherein the mounting block is slidably connected inside the sealing cylinder.

[0012] Preferably, a motor is fixedly mounted on the bottom of the mounting block, and a gear is fixedly connected to the output end of the motor.

[0013] Preferably, a toothed plate is fixedly installed on the inner wall of the sealing cylinder, and the toothed plate is meshed with the gear.

[0014] Preferably, the locking mechanism includes a fixed plate fixedly installed at the bottom of the mounting block, an electric telescopic rod fixedly installed through the fixed plate, a movable plate fixedly connected to the output end of the electric telescopic rod, and a locking rod fixedly installed on one side of the movable plate.

[0015] Preferably, a perforated plate is fixedly installed on the inner wall of the sealing cylinder, and a locking hole on the perforated plate is inserted into a locking rod. Two driven rods slide through the fixed plate, and the two driven rods are located on both sides of the electric telescopic rod. One end of the two driven rods is connected to the movable plate.

[0016] Preferably, the adjusting mechanism includes a rectangular cylinder hinged to the top of the slide rod, and a hand-twist screw is threaded between the rectangular cylinder and the slide rod.

[0017] Preferably, a fixing rod passes through the rectangular tube, and a fixing clip is fixedly installed at one end of the fixing rod, and the fixing clip is fixedly connected to the microphone;

[0018] A hand-twisting screw is threaded through one side of the rectangular tube, and one end of the hand-twisting screw abuts against the outer wall of the fixing rod.

[0019] The working principle and beneficial effects of this utility model are as follows: The motor drives the gear to rotate, causing the gear to roll on the gear plate. The linkage slide rod slides on the sealing cylinder for adjusting the height of the microphone. The electric telescopic rod pushes the movable plate forward, causing the locking rod to move forward and insert into the locking hole on the hole plate. While pushing the locking rod forward, the linkage driven rod slides on the fixed plate, making the forward push of the locking rod more stable and effectively fixing the microphone after the height adjustment, effectively preventing it from falling downward during use, thereby improving the stability of the microphone.

[0031] Example 1

[0032] Please refer to Figures 1-4. A microphone lifter structure includes: a fixed base 1 and a microphone 4.

[0033] The lifting mechanism 2 is located on top of the fixed base 1 and is used for adjusting the height of the microphone 4.

[0034] The locking mechanism 7 is located inside the lifting mechanism 2 and is used to lock the position of the microphone 4 after the lifting mechanism 2 has been adjusted.

[0035] The bottom of the fixed base 1 is fixedly installed with a circular rubber anti-slip pad 5 and multiple suction cups 6, and the multiple suction cups 6 are arranged in a circular array around the circular rubber anti-slip pad 5.

[0036] The circular rubber anti-slip pad 5, together with multiple suction cups 6, effectively fixes the base 1 to be placed stably and securely on the ground;

[0037] The lifting mechanism 2 includes a sealing cylinder 21 fixedly installed on the top of the fixed base 1, a slide rod 22 slidingly passing through the top of the sealing cylinder 21, a mounting block 23 fixedly connected to the bottom end of the slide rod 22, and the mounting block 23 is slidably connected inside the sealing cylinder 21. A motor 24 is fixedly installed at the bottom of the mounting block 23, and a gear 25 is fixedly connected to the output end of the motor 24. A toothed plate 26 is fixedly installed on the inner side wall of the sealing cylinder 21, and the toothed plate 26 is meshed with the gear 25. The locking mechanism 7 includes a locking mechanism fixedly installed on the mounting block 21. 3. A fixed plate 71 at the bottom is through which an electric telescopic rod 72 is fixedly installed.
