Description

Technical Field

[0001] This utility model relates to the field of antenna support technology, and in particular to a detachable UHF radio antenna support structure. Background Technology

[0002] The VHF radio antenna bracket is a support structure specifically designed for VHF / UHF band communication antennas. It combines modular components such as a base, support rod, and antenna connectors via mechanical connections (e.g., snap-fit, threads, pins) to achieve stable antenna fixation and height / angle adjustment, ensuring the continuity and directionality of VHF / UHF signal transmission. Its detachable design facilitates quick assembly and disassembly, and portability, while also considering mechanical balance and anti-interference performance (e.g., grounding and lightning protection, RF shielding). Suitable for field operations, emergency communications, and other scenarios, it is a key component for achieving reliable wireless communication in VHF / UHF radio systems.

[0003] Existing antenna brackets are often placed directly on the ground after assembly. However, when placed on uneven or muddy ground, the antenna brackets are unstable and prone to tipping over. Furthermore, existing antenna brackets cannot adjust the angle of the antenna mounting base. When the antenna bracket is erected on a slope, the tilt of the antenna mounting base will cause the antenna direction to deviate from the preset angle, resulting in distortion of the UHF signal coverage, shortened communication distance, or the appearance of blind spots, affecting the stability and reliability of signal transmission and reception.

[0024] In this embodiment, a magnetic ring 2 is fixedly sleeved on the outer side of the central column 1, and a magnetic ring base 18 is fixedly installed on the top of the positioning bracket 15. The magnetic ring 2 and the magnetic ring base 18 are adapted to each other, which facilitates the disassembly or installation of the central column 1.

[0026] In this embodiment, the adjustment mechanism includes a spring 6, a sliding wheel 7, a connecting column 8, and a fixed wheel 10. The sliding wheel 7 is slidably installed on the inner side of the adjustment groove. The connecting column 8 is fixedly installed on one side of the sliding wheel 7. The fixed wheel 10 is fixedly installed on the right side of the adjustment base 5. The fixed wheel 10 is adapted to the sliding wheel 7. The connecting column 8 slides through the fixed wheel 10. The spring 6 is fixedly installed on the inner wall of the left side of the adjustment groove. The other end of the spring 6 is fixedly connected to the sliding wheel 7. The sliding wheel 7 can be reset by the spring 6.

[0027] In this embodiment, the antenna mounting base 9 is fixedly installed on the right end of the connecting column 8, and the antenna mounting base 9 can be rotated by the connecting column 8.

[0028] In this embodiment, four support feet 12 are hinged to the outer side of the support bracket 11, and positioning suction cups 14 are fixedly installed at the bottom of each of the four support feet 12, which can enhance the anti-slip effect of the support feet 12.

[0029] In this embodiment, each of the four support feet 12 has an installation groove on one side, and an installation column 13 is fixedly installed on the inner side of each of the four installation grooves.

[0030] In this embodiment, four pneumatic rods 16 are hinged to the outside of the positioning bracket 15. One end of each of the four pneumatic rods 16 is fixedly installed with a hook buckle 17. The four hook buckles 17 are respectively engaged with the corresponding mounting column 13, so as to facilitate the connection of the pneumatic rods 16 to the support foot 12.

[0031] In this embodiment, motor slots are provided inside the four threaded sleeves 19, and servo motors 20 are fixedly installed on the inner side of the four motor slots. The hexagonal column 21 can be rotated by the servo motors 20.

[0032] In this embodiment, the positioning mechanism also includes a hexagonal column 21 and a threaded rod 22. The hexagonal column 21 is rotatably mounted on the top inner wall of the threaded sleeve 19. The output shaft of the servo motor 20 is fixedly connected to the hexagonal column 21. The threaded rod 22 is threadedly mounted on the inner side of the threaded sleeve 19. The threaded rod 22 is slidably sleeved on the hexagonal column 21. The pointed cone 23 is fixedly mounted on the bottom end of the threaded rod 22. The pointed cone 23 is driven into the ground by the movement of the threaded rod 22.

[0033] Working principle: During the assembly of the antenna bracket, firstly, the central column 1 is passed through the positioning bracket 15, so that the magnetic ring 2 on the outside of the central column 1 is magnetically connected to the magnetic ring base 18 on the positioning bracket 15. Then, the four support feet 12 are manually rotated to flip them over, so that the positioning suction cups 14 at their bottoms contact the ground. The four pneumatic rods 16 are then activated to extend them, so that the hooks and buckles 17 on them contact the mounting posts 13 on the corresponding support feet 12. The four hooks and buckles 17 are then engaged with the corresponding mounting posts 13, completing the unfolding and assembly of the bracket. Subsequently, the vacuum pump 3 and four servo motors 20 are activated. The vacuum pump 3 generates negative pressure, so that the vacuum suction cups 4 are tightly connected to the ground. The four servo motors 20 drive the corresponding hexagonal columns 21 to rotate. The rotation of the four hexagonal columns 21 drives the corresponding threaded rods 22 to rotate. The four threaded rods 22 are all threadedly installed on the inner side of the corresponding threaded sleeves 19. The four threaded sleeves 19 are all fixedly installed on the outside of the positioning bracket 15. Therefore, When the four threaded rods 22 rotate, they do not drive the corresponding threaded sleeves 19 to rotate. The four threaded rods 22 move axially, and the movement of the four threaded rods 22 drives the corresponding conical piles 23 to move down, so that they are driven into the ground, adapting to uneven or muddy ground, increasing the overall stability of the antenna support. When the antenna support is erected on a slope, the staff presses the antenna mounting base 9 to the left, causing it to drive the sliding wheel 7 to move away from the fixed wheel 10. At this time, the fixed wheel 10 will not cause movement interference to the sliding wheel 7. The staff can rotate the antenna mounting base 9 to a horizontal position, and then release the antenna mounting base 9. At this time, the rebound force generated by the spring 6 drives the sliding wheel 7, the connecting column 8 and the antenna mounting base 9 to move to the right. The sliding wheel 7 contacts the fixed wheel 10, and the tooth groove of the fixed wheel 10 limits the tooth groove of the sliding wheel 7 to prevent the sliding wheel 7 from rotating, completing the angle adjustment of the antenna mounting base 9, avoiding the antenna direction from deviating from the preset angle, and enhancing the stability and reliability of signal transmission and reception.

[0034] The technological advancements of this invention compared to existing technologies are as follows: the pointed cone pile 23 can be driven into the ground, adapting to uneven or muddy ground, thereby increasing the overall stability of the antenna support and preventing it from tipping over. Furthermore, through the set adjustment mechanism, when the antenna support is set on a slope, the antenna mounting base 9 can be kept horizontal, preventing the antenna direction from deviating from the preset angle, thus enhancing the stability and reliability of signal transmission and reception.
