[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an adjusting device for a broadcast signal transmitter, comprising a fixed box 1, an active cavity 2 is provided inside the fixed box 1, a mounting box 3 is fixedly connected to one side of the outer wall of the fixed box 1, a motor 4 is fixedly connected to the inner wall of the mounting box 3, a transmission shaft 5 is fixedly connected to the output end of the motor 4, the transmission shaft 5 is rotatably connected to the inner wall of the active cavity 2, a worm 6 is fixedly connected to the outer wall of the transmission shaft 5, a rotating shaft 7 is rotatably connected to the inner wall of the fixed box 1, a worm wheel 8 is fixedly connected to the outer wall of the rotating shaft 7, a rotating block 9 is fixedly connected to the upper surface of the worm wheel 8, the rotating block 9 is rotatably connected to the inside of the fixed box 1, and the upper surface of the rotating block 9 A fixed plate 10 is fixedly connected, a fixed seat 11 is fixedly connected to one side of the upper surface of the fixed plate 10, an articulated seat 12 is rotatably connected to the outer wall of the fixed seat 11, a signal transmitter 13 is fixedly connected to the outer wall of the articulated seat 12, and an adjustment component 14 is provided on the other side of the upper surface of the fixed plate 10; the adjustment component 14 includes an electric push rod 1401, the electric push rod 1401 is fixedly connected to the other side of the upper surface of the fixed plate 10, an articulated block 1402 is fixedly connected to the output end of the electric push rod 1401, the inner wall of the articulated block 1402 is rotatably connected to a support rod 1403, and the support rod 1403 is rotatably connected to one side of the outer wall of the signal transmitter 13;

[0023] Specifically, when the motor 4 is started, it starts to drive the transmission shaft 5 to rotate; the transmission shaft 5 transmits the rotational power of the motor 4 to the worm 6 so that the worm wheel 8 starts to rotate; due to the rotation of the worm wheel 8, the rotating block 9 will follow the angle rotation; this rotation effect causes the fixed plate 10 to rotate accordingly; the fixed plate 10 serves as a supporting component of the signal transmitting machine 13, and its rotation will drive the signal transmitting machine 13 to make corresponding angle adjustments; in this way, the preliminary angle adjustment of the signal transmitting machine 13 can be achieved; in order to achieve more precise adjustment of the signal transmitting machine 13, the electric push rod 14 is started 01 pushes the support rod 1403 inside the hinge block 1402 to move; the movement of the support rod 1403 will cause the angle between it and the hinge seat 12 to change; since the hinge seat 12 is fixed under the signal transmitting machine 13 and is connected to the outer wall of the fixed seat 11, the movement of the support rod 1403 will drive the hinge seat 12 to rotate on the outer wall of the fixed seat 11; this rotation effect further affects the angle of the signal transmitting machine 13, so that its angle can be adjusted more accurately; this design not only improves the flexibility and adaptability of the equipment, but also ensures the stability and reliability of signal transmission.

[0024] Reference Figure 1 , Figure 2 and Figure 3 , a rotating plate 15 is fixedly connected to the lower surface of the fixed box 1, and a connecting rod 16 is fixedly connected to the inner wall of the rotating plate 15; a stabilizing block 17 is rotatably connected to the outer wall of the connecting rod 16, and a mounting plate 18 is fixedly connected to the lower surface of the stabilizing block 17; a motor 2 19 is fixedly connected to the upper surface of the mounting plate 18, and a screw rod 20 is fixedly connected to the output end of the motor 2 19; a threaded sleeve 21 is threadedly connected to the outer wall of the screw rod 20, and a connecting rod 22 is rotatably connected to the outer wall of the threaded sleeve 21; a left-right symmetrical limiting rod 23 is fixedly connected to the upper surface of the mounting plate 18, and a sliding sleeve 24 is slidably connected to the outer walls of the two limiting rods 23; one side of the outer wall of the sliding sleeve 24 is fixedly connected to one end of the connecting rod 22, and the outer wall of the connecting rod 22 is rotatably connected to a support plate 25, and one side of the support plate 25 is rotatably connected to one side of the rotating plate 15;

[0025] Specifically, the screw rod 20 and the threaded sleeve 21 are driven by starting the second motor 19 to transmit the information. As the threaded sleeve 21 moves, it drives the outer wall of the connecting rod 22. The sliding sleeve 24 slides on the outer wall of the limiting rod 23. The design of the limiting rod 23 not only plays a guiding role, but also limits the movement range of the sliding sleeve 24 to prevent it from deviating from the predetermined track. When the connecting rod 22 is driven by the sliding sleeve 24 to move, the connecting rod 16 inside it will also move accordingly. The connecting rod 16 is designed to be adjusted in angle inside the stabilizing block 17. The stabilizing block 17 provides a stable environment for the movement of the connecting rod 16, ensuring its accuracy and reliability during the movement.

[0026] Working principle: When it is needed, the motor 21 is started to drive the screw rod 20 to drive the threaded sleeve 21 to transmit, and the movement of the threaded sleeve 21 drives the sliding sleeve 24 on the outer wall of the connecting rod 22 to slide on the outer wall of the limiting rod 23, and the movement of the connecting rod 22 drives the connecting rod 16 inside the rotating plate 15 to adjust the angle inside the stabilizing block 17.

[0027] Secondly, by starting the motor 4, the transmission shaft 5 is driven by the motor 4 to make the worm 6 mesh with the worm wheel 8 and rotate, and the rotation of the worm wheel 8 makes the rotating block 9 above the rotating shaft 7 rotate at an angle. At this time, the rotating block 9 drives the fixed plate 10 to rotate, so as to achieve the effect of driving the signal transmitting machine 13 to further adjust the angle. At this time, by starting the electric push rod 1401, the electric push rod 1401 drives the support rod 1403 inside the hinge block 1402 to move, and the rotation of the support rod 1403 achieves the effect of facilitating the rotation of the hinge seat 12 below the signal transmitting machine 13 on the outer wall of the fixed seat 11, and the rotation of the hinge seat 12 achieves the effect of facilitating the adjustment of the signal transmitting machine 13.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
