Abstract
Description
Technical Field
[0001] The invention relates to the field of frequency components, in particular to a radio frequency antenna angle adjustment bracket. Background Art
[0002] New frequency components include RF antennas, which are used in radio communications, wireless networks and broadcasting systems. They usually operate in a lower frequency range. The function of the antenna inside the RF antenna is mainly to convert electrical signals into electromagnetic waves, or to convert received electromagnetic waves into electrical signals. Secondly, the design and type of RF antennas can be divided into different categories according to their structure and operating frequency, such as directional antennas, omnidirectional antennas, sector antennas, etc. Directional antennas can send signals in a concentrated direction, which means that the antenna can concentrate the electromagnetic wave energy in certain specific directions; for receiving antennas, it means that they have a strong receiving ability for electromagnetic waves from certain specific directions.
[0003] After massive searches, it was found that the prior art publication number is CN113612024A, which discloses a three-axis antenna scanning frame, which avoids repeated position conversion and installation and disassembly of antennas, improves test efficiency and the reliability and stability of measurement results, and effectively solves the problem that the entire space signal cannot be tested after one installation.
[0004] Therefore, based on the above search and combined with the prior art, it is found that in actual use, only movement and adjustment within a range can be performed, and the angle of the antenna cannot be adjusted. When measuring directional antennas, accurate measurement cannot be achieved. Directional antennas enhance the signal transmission and reception capabilities in a specific direction, thereby improving the communication quality and distance in that direction. The narrower the beam width, the higher the antenna gain and the farther the signal propagates, but this also means that the signal deviates from the main lobe direction. The attenuation will be faster. Secondly, the polarization direction of the antenna is also an important factor affecting the reception effect. If the polarization direction of the receiving antenna does not match the polarization direction of the incoming wave, such as one horizontal polarization and the other vertical polarization, then the receiving antenna will not be able to effectively receive the signal. For this reason, we propose an RF antenna angle adjustment bracket. Summary of the invention

[0042] Working principle of the present invention: Please refer to Figures 3 to 5When in use, the base 1 is placed at the required scanning position. When the antenna angle needs to be adjusted by using a horizontal line as an angle reference, the drive ring 3 is rotated. The rotation of the drive ring 3 drives the fastening spring 17 to compress and the tension spring 19 to stretch, so that the two drive rods 21 move inside the protective shell 2, so that the two drive rods 21 slide inside the corresponding inclined grooves 22. Since the two inclined grooves 22 are arranged at an angle, the two drive rods 21 slide inside the corresponding inclined grooves 22, driving the two arc plates 14 to rotate outside the corresponding rotating shaft 13, so that one end of the two arc plates 14 is separated from the outside of the corresponding first rotating rod 4, and at the same time, one side of the two stop blocks 15 is aligned with the corresponding first rotating rod 4. , the two return springs 57 retract and drive the corresponding first rotating rods 4 to move, so that one end of the two first rotating rods 4 is separated from one side of the corresponding fixed plate 24, so that the two return springs 25 extend and drive the two fixed plates 24 to move. The two fixed plates 24 move so that both ends of the two fixed plates 24 are separated from the outside of the corresponding second rotating rods 6, so that the ring 5 and the circular plate 7 can rotate freely. At the same time, the weight of the counterweight 8 is used to drive the ring 5 and the circular plate 7 to rotate. When the top of the circular plate 7 is parallel to the horizontal plane, the rotation is stopped, and the orientation direction of the antenna can be perpendicular to the horizontal line. At this time, the orientation direction of the antenna can be accurately adjusted in angle.
[0043] After the angle adjustment is completed, the drive ring 3 is released, so that the fastening spring 17 extends and the tension spring 19 retracts, driving the drive ring 3 to rotate. The rotation of the drive ring 3 drives the two drive rods 21 to slide inside the protective shell 2, so that the two drive rods 21 slide inside the corresponding inclined grooves 22, and drive the corresponding arc plate 14 to rotate, so that one end of the two arc plates 14 abuts against one side of the corresponding first rotating rod 4. At the same time, since the other ends of the two arc plates 14 are fixedly connected with the abutment blocks 15, the rotation of the two arc plates 14 drives the two abutment blocks 15 to abut against one side of the corresponding first rotating rod 4. At the same time, since one side of the two first rotating rods 4 is conically arranged, the two first rotating rods 4 slide to the opposite side, and the two first rotating rods 4 slide and drive and respectively abut against the corresponding two fixed plates 24, so that the two return springs 25 are compressed. At the same time, the two ends of the two fixed plates 24 respectively abut against the outside of the corresponding second rotating rod 6, so that the ring 5 and the circular plate 7 are fixed to each other, completing the fixation after the angle adjustment.
[0044] See also Figure 7 and Figure 8When the contact surface at the bottom of the base 1 is used as an angle reference to adjust the angle of the antenna, the drive ring 3 is rotated at this time so that the circular ring 5 and the circular plate 7 can rotate freely. At this time, the drive ring 3 is continued to be rotated. The drive ring 3 rotates to drive the protective shell 2 to rotate. The protective shell 2 rotates to drive the four connecting plates 38 of the first rotating rod to rotate. The four connecting plates 38 of the first rotating rod rotate to drive the corresponding sliding plates 39 to slide inside the corresponding sliding grooves 34, so that the four sliding plates 39 of the first rotating rod are separated from the corresponding positioning plates 32. At this time, the four positioning springs 33 are extended and drive the corresponding positioning springs 33 to rotate, so that one end of the four positioning springs 33 is in contact with the bottom of the counterweight 8. Since the elastic force of the four positioning springs 33 is the same, the bottom of the counterweight 8 is parallel to the base 1. Since the base 1 is placed on the contact surface, the base 1 is parallel to the contact surface at this time, so that the top of the circular plate 7 is parallel to the ground, and the telescopic rod 11 is perpendicular to the ground. At this time, the drive ring 3 is released to complete the fixation, so that the directional direction of the antenna is perpendicular to the contact surface at the bottom of the base 1. At this time, the directional direction of the antenna can be accurately adjusted.
[0045] See also Figures 9 to 12 After the reference object is set, when the directional direction of the antenna needs to be adjusted in angle, the limit sleeve 48 is slid at this time, and the movement of the limit sleeve 48 drives the sliding sleeve 46 to move, and at the same time, the movement of the limit sleeve 48 drives the swivel 54 to move, the movement of the swivel 54 drives the inclined plate 53 to move, the movement of the inclined plate 53 drives the measuring block 45 to move, the movement of the measuring block 45 drives the linkage rod 44 to move, and the movement of the linkage rod 44 drives the mounting plate 43 to move, so that the angle of the mounting plate 43 can be adjusted. During the adjustment process, the angle change can be observed by the electronic protractor 56. During the sliding process of the limit sleeve 48, the two sides of the sliding sleeve 46 contact the limit blocks 51 on both sides of the inner wall of the measuring tube 41, and each One contact represents a large angle. After sliding to the required large angle, the opposite sides of the two corresponding limit blocks 51 abut against the inside of the corresponding third limit groove 52 to fix the sliding sleeve 46. At this time, the swivel 54 is rotated according to the required angle. The rotation of the swivel 54 drives the driving block 55 to rotate. During the rotation of the driving block 55, it contacts one side of the inclined plate 53. At this time, since the inclined plate 53 is arranged in an arc shape, the driving block 55 rotates and drives the inclined plate 53 to move up and down. The up and down movement of the inclined plate 53 drives the measuring block 45 to move up and down. The up and down movement of the measuring block 45 drives the linkage rod 44 to move. The movement of the linkage rod 44 drives the mounting plate 43 to move, so that the rotation angle of the antenna is more precise.
