Description

Technical Field

[0001] This utility model belongs to the field of antenna equipment technology, and in particular relates to a concentric portable antenna polarization rotating bracket. Background Technology

[0002] An antenna is an electromagnetic wave transducer that converts traveling waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa, to transmit or receive electromagnetic waves. Engineering systems that utilize electromagnetic waves to transmit information, such as radio communication, broadcasting, television, radar, navigation, electronic warfare, remote sensing, and radio astronomy, all rely on antennas. Most existing antennas are linearly polarized antennas, and two important performance indicators are crucial during their use:

[0003] 1) Polarization rotation: Linear polarization antennas generally have high polarization isolation. To achieve excellent transmission performance, it is necessary to keep the polarization of the antenna and the test object consistent. During the test, the antenna polarization needs to be adjusted repeatedly to achieve the best test results. Portable and efficient polarization adjustment is crucial for test efficiency.

[0004] 2) Antenna and target alignment: To improve signal transmission, antenna gain is typically designed to be high during experiments. Ensuring proper alignment between the antenna and target is crucial. Before testing, repeated adjustments to the antenna's height, angle, and other positional information are necessary, a tedious and time-consuming process. Since the antenna polarization needs repeated adjustments during testing, it's essential to minimize the impact of polarization rotation on alignment, ensuring that the rotation doesn't affect the antenna's axis.

[0005] Existing antenna brackets are highly specialized and have poor expandability to accommodate multiple types of antennas. Different types and sizes of antennas require separately designed installation clamps, which are inconvenient to use, time-consuming, labor-intensive, and expensive. Utility Model Content

[0007] To solve the above problems, the present invention adopts the following technical solution:

The polarization rotation stage is provided with multiple sets of mounting holes. Each set of mounting holes includes several mounting holes arranged in a ring around the axis of the bearing. The distance between each set of mounting holes and the axis of the bearing is different.

[0009] Preferably, the polarization rotating platform has a plurality of hemispherical holes arranged in a ring at equal intervals on the outer side of the bearing, and the surface of the vertical fixing plate has a plurality of first threaded holes coaxial with any of the hemispherical holes.

[0010] Preferably, the polarization rotating stage is provided with 8 hemispherical holes, and the surface of the vertical fixing plate is provided with 4 first threaded holes.

[0011] Preferably, a pin hole is provided on the outside of each hemispherical hole on the polarization rotating stage, and a second threaded hole coaxial with any pin hole is provided on the surface of the vertical fixing plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3As shown, this utility model provides a technical solution: a concentric portable antenna polarization rotating bracket, including a horizontal fixing plate 1, a vertical fixing plate 2, a reinforcing rib 3, a polarization rotating platform 4, and a bearing 5. The horizontal fixing plate 1 is horizontally arranged, and the vertical fixing plate 2 is vertically connected to the top of one end of the horizontal fixing plate 1. The reinforcing rib 3 is connected between the horizontal fixing plate 1 and the vertical fixing plate 2. The polarization rotating platform 4 is rotatably connected to the surface of the vertical fixing plate 2. The bearing 5 is connected between the polarization rotating platform 4 and the vertical fixing plate 2. The inner ring of the bearing 5 is fixedly connected to the vertical fixing plate 2, and the outer ring of the bearing 5 is fixedly connected to the polarization rotating platform 4. The polarization rotating platform 4 is provided with multiple sets of mounting holes 41. Each set of mounting holes 41 includes several mounting holes 41 arranged in a ring around the axis of the bearing 5. The distance between each set of mounting holes 41 and the axis of the bearing 5 is different.

[0024] This utility model improves the versatility of the bracket by setting multiple sets of mounting holes 41 on the polarization rotary table 4 for mounting antenna equipment of different sizes, and meets the needs of different types and sizes of antenna equipment. Each set of mounting holes 41 includes several mounting holes 41 arranged in a ring around the axis of the bearing 5. The distance between each set of mounting holes 41 and the axis of the bearing 5 is different. The axis of each set of mounting holes 41 is coaxial with the axis of the bearing 5, so that the axis of the antenna equipment is coaxial with the axis of the bearing 5, ensuring that the axis of the antenna equipment does not deviate when the antenna equipment is scheduled to rotate.

[0025] Furthermore, the polarization rotary table 4 is provided with a plurality of hemispherical holes 6 arranged in an annular pattern at equal intervals on the outer side of the bearing 5. The surface of the vertical fixing plate 2 is provided with a plurality of first threaded holes 21 coaxial with any of the hemispherical holes 6. The first threaded holes 21 are internally threaded with hexagonal ball head screws 7. The steel ball at the end of the hexagonal ball head screw 7 abuts against the hemispherical hole 6, thereby dividing the polarization rotary table 4 into a plurality of equal parts, so that the polarization rotary table 4 rotates at a fixed angle, and after the angle is adjusted, the polarization rotary table 4 is fixed by the hexagonal ball head screws 7.

[0026] Specifically, the polarization rotating stage 4 is provided with 8 hemispherical holes 6, and the surface of the vertical fixing plate 2 is provided with 4 first threaded holes 21, thereby dividing the polarization rotating stage 4 into 8 equal parts, which can rotate 45° each time.

[0027] Furthermore, a pin hole 8 is provided on the outside of each hemispherical hole 6 on the polarization rotary table 4, and a second threaded hole 22 coaxial with any pin hole 8 is provided on the surface of the vertical fixing plate 2. A knurled head spring plunger 9 is internally threaded into the second threaded hole 22, and the pin at the end of the knurled head spring plunger 9 is inserted into the pin hole 8, thereby locking it after the polarization rotary table 4 rotates to prevent the antenna equipment from shaking and affecting the test results.

[0028] Furthermore, the horizontal fixing plate 1 is provided with a plurality of connection holes 11 at intervals along the extension direction of the horizontal fixing plate 1, so as to facilitate the adjustment of the connection position between the horizontal fixing plate 1 and the external triangular support frame according to the antenna equipment of different sizes, and to adjust the center of gravity of the rotating bracket and the antenna equipment to be located at the center of the triangular support frame to avoid tipping over.

[0029] Furthermore, the horizontal fixing plate 1 and the vertical fixing plate 2 are respectively provided with hollow holes 12 for weight reduction, which reduces the overall weight of the rotating bracket and makes the rotating bracket more portable.

[0030] Furthermore, the bearing 5 is a slewing bearing crossed roller bearing, which can withstand large radial and axial loads, while having high rigidity and precision, further improving the accuracy of the antenna equipment's polarization rotation to maintain coaxiality.
