[0023] like Figure 1-2 As shown, an embodiment of the utility model provides an antenna rotation structure, including: a base, which includes a horizontally arranged bottom plate 1 and a support 2 fixedly installed on the upper part of the bottom plate 1; and a rotating mechanism, which includes a driving part fixedly installed in the support 2, a supporting part arranged above the support 2, a connecting part tiltably and rotatably installed on the upper part of the supporting part, a mounting part rotatably installed on the side of the connecting part away from the supporting part, and a limiting part arranged between the support 2 and the connecting part, the power output end of the driving part is connected to the supporting part, the angle between the connecting part and the vertical direction is an acute angle, the limiting part is used to limit the swing of the connecting part, and a locking part is provided between the mounting part and the connecting part for fixing the angle of the mounting part.

[0024] The antenna structure is fixed on the mounting part, and the angle of the mounting part is adjusted. After the adjustment is in place, it is fixed by the locking part, and then the driving part is started to drive the supporting part to rotate. Due to the limiting effect of the limiting part, the connecting part will not rotate synchronously with the supporting part, but will drive the mounting part and the antenna to swing along its circumferential direction, so that the angle of the antenna mechanism can be adjusted arbitrarily. When the position of the antenna structure is adjusted to the right position, the driving part is stopped. The operation is simple and convenient, the angle of the antenna can be adjusted quickly, and the adjustment range of the antenna angle is large, no manual operation is required, and the adjustment efficiency of the antenna angle is improved.

[0025] like Figure 2-4As shown, according to another embodiment of the utility model, the antenna rotation structure further optimizes the supporting part, connecting part, mounting part, limiting part, locking part and driving part included therein, and the supporting part includes a fixed block 4 and a supporting plate 5, the lower part of the fixed block 4 is fixedly connected to the power output end of the driving part, the upper part of the fixed block 4 is an inclined surface, the support plate 5 is fixedly connected to the inclined surface of the fixed block 4, and the connecting part is rotatably installed on one side of the upper part of the support plate 5.

[0026] The connecting portion includes a connecting rod 6 vertically rotatably mounted on the support plate 5, the limiting portion is arranged between the support 2 and the connecting rod 6, and the mounting portion is rotatably connected to one end of the connecting rod 6 away from the support rod; a limiting rod 21 is vertically fixedly installed on the upper part of the support 2, and a limiting hole 22 is provided on the limiting rod 21, and the limiting portion includes a connecting sleeve 64, a rotating rod 65 and a limiting frame 66 which are coaxially arranged in sequence, the connecting sleeve 64 is vertically fixedly mounted on the side wall of the connecting rod 6, one end of the rotating rod 65 is rotatably connected to the connecting sleeve 64, and the other end is connected to the limiting frame 66 Fixedly connected, the limit frame 66 is a U-shaped structure, a sliding rod 67 is fixedly installed between the two opposing inner walls of the limit frame 66, the limit rod 21 is located between the two opposing inner walls of the limit frame 66, the sliding rod 67 freely passes through the limit hole 22 and is slidably connected thereto, and the shape of the limit hole 22 is the same as the rotation trajectory of the sliding rod 67; during the rotation of the support plate 5, the rotating rod 65 and the connecting sleeve 64 rotate relative to each other, and the sliding rod 67 slides back and forth along the limit hole 22, thereby ensuring that the connecting rod 6 will not rotate synchronously with the support plate 5, but will swing along its circumference.

[0027] Two brackets 61 are fixedly installed facing each other on one end of the connecting rod 6 away from the supporting plate 5, and the mounting portion includes a mounting plate 7 and a rotating plate 71 fixedly connected to one side of the mounting plate 7, the rotating plate 71 is rotatably installed between the two brackets 61, and the locking portion is arranged between the rotating plate 71 and the two brackets 61; mounting holes 62 are provided on the two brackets 61 and the rotating plate 71, and the locking portion includes a locking bolt 8 freely passing through three mounting holes 62 and a butterfly nut 9 threadedly assembled therewith; and preferably, the aperture of one end of the mounting hole 62 on one bracket 61 close to the other bracket 61 is smaller than the aperture of the other end thereof, and the cross-sectional shape of the mounting hole 62 is the same as the shape of the bolt head of the locking bolt 8, so that the bolt head of the locking bolt 8 can be easily inserted into the mounting hole 62, thereby making it more labor-saving and convenient to screw the butterfly nut 9.

[0028] The driving part includes a motor 3 fixedly installed in the support 2, and the power output shaft of the motor 3 freely passes through the support 2 and is fixedly connected to the lower part of the fixed block 4, so as to provide power for the rotation of the fixed block 4 and the support plate 5.

[0029] like Figure 1-2As shown, according to another embodiment of the utility model, in the antenna rotation structure, preferably, each bracket 61 has a semicircular end away from the connecting rod 6, wherein a scale 63 is provided on the side wall of one bracket 61 along its semicircular circumference, and a pointer 72 is fixedly installed on the bottom of the mounting plate 7; by indicating the scale 63 through the pointer 72, the angle of the mounting plate 7 can be clearly observed, so as to adjust the angle of the antenna structure.

[0030] The use principle of the present utility model is as follows: when the present utility model is used, first loosen the butterfly nut 9, then rotate the mounting plate 7, and adjust the angle of the mounting plate 7 by indicating the scale 63 with the pointer 72. After adjusting to the right position, tighten the butterfly nut 9, and then fix the antenna structure on the mounting plate 7. Then start the motor 3 to drive the fixing block 4 and the support plate 5 to rotate. Due to the limiting effect of the sliding rod 67, the limiting frame 66, the rotating rod 65 and the connecting sleeve 64, the connecting rod 6 will not rotate synchronously with the support plate 5, but will drive the sliding rod 67 to slide back and forth in the limiting hole 22, and at the same time drive the rotating rod 65 and the connecting sleeve 64 to rotate relative to each other, so that the connecting rod 6 drives the mounting plate 7 and the antenna to swing along its circumferential direction. When the antenna swings to the specified angle, stop the motor 3.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
