Since the speakers are heavy and large, and the mounting frame is high off the ground, the workers have to work very hard during the lifting process, and the speakers are easily damaged due to loss of strength. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a mounting bracket for stage speakers, in which a servo motor drives a threaded shaft to rotate, and the rotation of the threaded shaft drives a skateboard arc frame and a rotating frame to move downward first, and then drives the rotating frame upward after the speakers are placed on them, thereby realizing the use of a lifting mechanism to lift the speakers, thereby facilitating the movement of heavier speakers onto the mounting bracket, reducing the labor intensity of the staff, and preventing the staff from losing their strength and causing the speakers to break.

[0007] The technical solution to achieve the purpose of the utility model is: a mounting frame for stage sound, comprising a support column, a top end of which is provided with a movable groove, a movable column is slidably connected in the movable groove, and further comprising;

[0008] A fixed box, wherein the fixed box is fixedly connected to the movable column;

[0009] A lifting mechanism, wherein the lifting mechanism is located on the fixed box;

[0010] The lifting mechanism includes a fixed track fixedly connected to the bottom of the fixed box, a slide plate is slidably connected to the fixed track, one end of the slide plate is fixedly connected to an arc frame, both ends of the arc frame are fixedly connected to fixed shafts, and rotating frames are rotatably sleeved on the two fixed shafts. A servo motor is fixedly connected to the bottom inner wall of the fixed box, and the output end of the servo motor is connected to a threaded shaft through a coupling. A rotating hole is opened on the bottom inner wall of the fixed box, and the bottom end of the threaded shaft passes through the rotating hole and is fixedly connected to the bottom end of the fixed track, and the slide plate is slidably connected to the threaded shaft.

[0011] In some embodiments, the inner arc walls of the two rotating frames are provided with notch grooves, and the bottom end of the fixed box is fixedly connected to two fixing columns, which are respectively located in the two notch grooves and in contact with the rotating frames.

[0012] In some embodiments, the two rotating frames are both C-shaped, and the two fixing columns are both made of magnets.

[0013] In some embodiments, a rotating plate is provided above the fixed box, a circular groove is provided at the bottom of the rotating plate, the top of the fixed box is rotatably connected in the circular groove, an annular ring is fixedly connected to the top of the fixed box, and the top of the annular ring contacts the top inner wall of the circular groove.

[0015] In some embodiments, three supporting feet are fixedly connected to the outer cylindrical wall of the bottom end of the support column, and the three supporting feet are evenly distributed.

[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] First, the utility model uses the setting of the lifting mechanism to pull out the two rotating frames, start the servo motor to drive the threaded shaft to rotate, the threaded shaft rotates to drive the slide plate, the slide plate moves to drive the arc frame and the rotating frame to move, and then can drive the speaker to lift. During the lifting process of the slide plate, the user drives the threaded rod to rotate through the crank to make the fixed track contact the ground, and then waits for the slide plate to drive the arc frame and the rotating frame to move to the bottom of the fixed track, and moves the speaker to the two rotating frames, realizing the lifting of the speaker by the lifting mechanism, and then facilitating the lifting of the heavier speaker to the installation frame, reducing the labor intensity of the staff, and at the same time preventing the staff from losing their strength and causing the speaker to break;

[0018] Second, the utility model can drive the speaker to rotate by rotating the rotating plate. Since the annular ring is made of rubber, the rotating plate and the annular ring have a damping effect.
