Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a double-ridged horn antenna. Background Technology

[0002] As a broadband directional antenna, the double-ridged horn antenna is widely used in microwave communication, radar detection, electromagnetic compatibility testing and other fields. By setting a ridge structure on the inner wall of the horn, it effectively expands the operating bandwidth and improves the signal transmission and reception performance.

[0003] However, existing dual-ridge horn antennas still have many shortcomings. Common antennas have poor angle adjustment flexibility, most products adopt a fixed installation structure, making it difficult to flexibly adjust the radiation direction according to the needs of actual use scenarios, resulting in limited adaptability. Furthermore, the installation structure of the internal ridge plate of the antenna is inconvenient, requiring disassembly and assembly in a confined space. When matching different frequency bands, the ridge plate of different specifications and sizes needs to be replaced, which increases the antenna debugging time. Therefore, this application proposes a dual-ridge horn antenna. Utility Model Content

[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0040] Please see Figures 1-8 This utility model provides a technical solution: a double-ridged horn antenna, including a mounting plate 1, which is a rectangular plate placed vertically. An adjustment plate 2 is provided on the right side of the mounting plate 1, and a mounting groove 21 is formed on the right side of the adjustment plate 2. A connecting component 11 is provided at the middle position between the mounting plate 1 and the adjustment plate 2. Adjustment components 12 are provided at the four corners between the mounting plate 1 and the adjustment plate 2. A horn-shaped body 4 is provided on the right side of the adjustment plate 2, and a mounting base 3 is installed at the left end of the body 4. The mounting base 3 is embedded in the mounting bracket on the side of the adjustment plate 2. Inside the mounting slot 21, guide plates 41 with a U-shaped cross section are installed on the top and bottom of the inner wall of the main body 4. Ridge plates 5 are slidably installed between the two guide plates 41. Limiting components 44 are set between the two guide plates 41. By reasonably setting the structure and positional relationship of the mounting plate 1, adjusting plate 2, connecting component 11, adjusting component 12, main body 4, mounting base 3, ridge plate 5 and limiting component 44, a complete double-ridge horn antenna structure is constructed, which lays the foundation for subsequent angle adjustment and flexible replacement of ridge plate 5. The coordinated work of each component can ensure the realization of the basic functions of the antenna.

[0041] like Figure 3 and Figure 4As shown, a positioning rod 43 is provided between the recessed parts of the two guide plates 41. A limiting tooth groove 431 is opened on the outer wall of the right half of the two positioning rods 43. A through hole 51 fitted on the positioning rod 43 is opened on the side of the two ridge plates 5 that fits into the body 4. The limiting component 44 is slidably installed between the recessed parts of the guide plates 41 and in contact with the ridge plates 5. The cooperation between the positioning rod 43 and the through hole 51 on the ridge plate 5 guides the sliding of the ridge plate 5, ensuring the stable movement of the ridge plate 5. The contact between the limiting component 44 and the ridge plate 5 provides structural support for the subsequent limiting and fixing of the ridge plate 5, and improves the stability of the ridge plate 5 installation.

[0042] like Figure 5 and Figure 6 As shown, the limiting assembly 44 includes an L-shaped limiting baffle 441, a limiting plate 443, a first bolt 445, a pressing plate 447, and a second bolt 448. The horizontal portion of the limiting baffle 441 is slidably installed in the recessed portion of the guide plate 41, and the horizontal portion of the limiting baffle 441 has an opening that fits onto the positioning rod 43. The top of the inner wall of the opening has a first groove 442, and the limiting plate 443 is installed in the first groove 442. The bottom of the limiting plate 443 is provided with teeth that are adapted to the limiting tooth groove 431 at the top of the positioning rod 43. Springs 444 are fixedly connected to both ends of the top of the limiting plate 443 and the first groove 442. The first bolt 445 is threaded into the horizontal portion of the limiting baffle 441 and extends into the first groove 442 to connect with the limiting plate 443. The vertical portion of the limiting baffle 441, near the ridge plate 5, has a second groove 446. The pressing plate 447 is movably inserted into the second groove 446, and a bearing is provided at one end of the pressing plate 447 located in the second groove 446. The second bolt 448 is threaded into the vertical portion of the limiting baffle 441 and extends into the second groove 446 to be fixedly connected to the bearing. The multiple structural designs of the limiting assembly 44 achieve double fixation of the ridge plate 5. The bottom teeth of the limiting plate 443 cooperate with the upper positioning groove 431 of the positioning rod 43 to fix the position of the limiting baffle 441. The pressing plate 447 can press the ridge plate 5. The locking and unlocking of the ridge plate 5 can be easily achieved by adjusting the first bolt 445 and the second bolt 448, which simplifies the replacement process of the ridge plate 5 and facilitates quick debugging.

[0043] like Figure 4 and Figure 6As shown, the corner of the outer wall of the limiting baffle 441 and the end of the extrusion plate 447 located outside the second groove 446 are both set in an arc shape. The inner wall of the guide plate 41 is provided with sliding grooves 42 on both sides. Sliding blocks are installed on both sides of the horizontal part of the limiting baffle 441. The two sliding blocks are respectively slidably installed in the sliding grooves 42 on both sides of the inner wall of the guide plate 41. The arc-shaped design of the limiting baffle 441 and the extrusion plate 447 can reduce friction and collision with other components and protect the components. The cooperation between the sliding grooves 42 and the slider makes the limiting baffle 441 slide more smoothly and improves the smoothness of the adjustment of the limiting component 44.

[0044] like Figure 7 and Figure 8 As shown, the connecting assembly 11 includes a connecting rod 111 and a sleeve rod 112. The connecting rod 111 is fixedly connected to the center of the side of the mounting plate 1, and the end of the connecting rod 111 away from the mounting plate 1 is spherical. The sleeve rod 112 is fixedly installed at the center of the side of the adjusting plate 2, and the end of the sleeve rod 112 away from the adjusting plate 2 is provided with a semi-circular groove. The spherical end of the connecting rod 111 is located in the semi-circular groove and can rotate inside it. The connecting assembly 11 provides a flexible rotation fulcrum for the angle adjustment between the mounting plate 1 and the adjusting plate 2, ensuring the basic feasibility of angle adjustment.

[0045] like Figure 7 and Figure 8 As shown, the adjustment assembly 12 includes a first universal joint, a hydraulic rod, and a second universal joint. The second universal joint is fixedly installed at the corner of the side of the mounting plate 1, and the first universal joint is fixedly installed at the corner of the side of the adjustment plate 2. The two ends of the hydraulic rod are respectively hinged to the first universal joint and the second universal joint. The four sets of adjustment assemblies 12 can precisely adjust the tilt angle of the adjustment plate 2 and the main body 4 by means of the extension and retraction of the hydraulic rod and the multi-angle hinge of the first universal joint and the second universal joint, so as to realize the flexible adjustment of the antenna radiation direction and greatly improve the adaptability of the antenna to different usage scenarios.

[0046] like Figure 1 and Figure 7 As shown, the top of the adjustment plate 2 has two first insertion holes that pass through the mounting groove 21, and the mounting base 3 has two second insertion holes that pass through vertically. Locking bolts 22 are inserted between the two first insertion holes and the corresponding second insertion holes. The locking bolts 22 pass through the corresponding insertion holes of the adjustment plate 2 and the mounting base 3, which can firmly fix the mounting base 3 in the mounting groove 21 of the adjustment plate 2, ensuring the stability of the main body 4, avoiding loosening during use, and improving the overall stability of the antenna structure.
