Problems solved by technology
[0003] Most of the existing antennas are mostly directional or small-angle rotating, which have defects in signal reception. A small number of omnidirectional antennas have complex structures and high production costs, so they are not suitable for wide-scale promotion.

Embodiment Construction
[0016] In order to make the technical solution of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings. Any solution obtained by equivalent replacement and conventional reasoning of the technical features of the technical solution of the present invention falls within the protection scope of the present invention.
[0017] As shown in the figure, a freely adjustable antenna includes a bracket 1 and an antenna. It is characterized in that the bracket 1 includes a mounting base plate 2 and a support rod 3. Evenly distributed installation holes 4, the lower end of the support rod 3 is welded and fixed vertically with the installation base plate 2, and is located at the center of the square formed by the installation base plate 2. The support rod 3 is provided with a cardan shaft 5 and a rotating mechanism. The shaft 5 is fixedly arranged on the upper end of the support rod 3;
[0018] The rotating mecha...

The invention discloses an antenna with a freely adjustable angle. The antenna comprises a support and an antenna body, the support comprises a mounting bottom plate and a supporting rod, and a universal shaft and a rotating mechanism are arranged on the supporting rod; the universal shaft and the rotating mechanism are connected with the middle part and the bottom of an antenna installing rod respectively; the rotating mechanism comprises a rotating motor, a bearing, a first bevel gear and a second bevel gear. Compared with most existing directional or small-angle rotary type antennas, the rotating motor is used for controlling the rough direction of the antenna, and then angle adjustment is carried out through an electric telescopic rod, so that the antenna is convenient to use; comparedwith few omni-directional antennas, the structure is simpler, the manufacturing process difficulty and the cost are greatly reduced, and the antenna is suitable for large-scale production and popularization.
Description
technical field [0001] The invention relates to an antenna, in particular to an antenna whose angle can be freely adjusted. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. [0003] Most of the existing antennas are mostly directional or small-angle rotating, which have defects in signal reception. A small number of omnidirectional antennas have complex structures and high production costs, so they are not suitable for wide-scale promotion. Contents of the invention [0004] In view of the above problems, the present invention proposes an antenna with freely adjustable angle. [0005] The specific technical scheme is as follows: [0006] An antenna with freely adjustable angles, including a bracket and an antenna, characterized in that the bracket includes a mounting base plate and a support rod, th...
