[0002] The double-ridged horn antenna is a broadband antenna operating between 1 GHz and 18 GHz with a gain of 10 to 20 dBi. Its unique double-ridged design not only increases bandwidth but also reduces signal loss. Therefore, the double-ridged horn antenna is ideal for applications requiring precise, long-distance signal transmission, such as electromagnetic compatibility testing and radar systems.

[0003] Existing double-ridged horn antennas are mostly fixed in place with multiple screws during installation. Although this method provides good installation stability, its drawback is that when the double-ridged horn antenna malfunctions or needs to be disassembled for other reasons, disassembly requires unscrewing all the fixing screws one by one, which is very troublesome and inconvenient for use in places where frequent disassembly and assembly are required.

[0004] Therefore, a miniaturized double-ridged horn antenna that is easy to disassemble is needed. Utility Model Content

[0006] To achieve the above objectives, the present invention proposes the following specific solutions:

[0007] A miniaturized dual-ridge horn antenna includes a rectangular frame. An antenna body is movably inserted into the inner side of the rectangular frame. A rectangular block is fixed to one end of the antenna body and is movably inserted into the inner side of the rectangular frame. The sidewall of the rectangular block is symmetrically provided with limiting grooves. The outer wall of the rectangular frame is symmetrically provided with through holes that communicate with the inner side of the rectangular frame. A movable plate is symmetrically provided on the outer side of the rectangular frame. A limiting rod is fixed to one side wall of the movable plate and passes through the through hole. One end of the limiting rod is movably inserted into the inner side of the limiting groove. A vertical plate is fixed to one end of the movable plate. A first spring is provided on one side of the rectangular frame, and the end of the first spring is fixed to the side wall of the movable plate. A fixing frame is fixed to one side wall of the rectangular frame and is located outside the first spring. A rectangular hole is provided in the middle of the outer wall of one side of the fixing frame and communicates with the inner side of the fixing frame. A trapezoidal plate is provided inside the fixing frame and is located on one side of the vertical plate. A rectangular rod is fixed in the middle of the side wall of the trapezoidal plate and passes through the rectangular hole. A push-pull block is fixed to one end of the rectangular rod.

[0008] As a preferred technical solution of the miniaturized double-ridged horn antenna of this utility model, a second spring is fixed on one side wall of the push-pull block, the second spring is sleeved on the outside of the rectangular rod, and one end of the second spring is fixed on the outer wall of the fixing frame.

[0009] As a preferred technical solution of the miniaturized double-ridged horn antenna of this utility model, the side wall of the movable plate is provided with a first movable hole, the first movable hole is located on one side of the limiting rod, and the outer wall of the rectangular frame is symmetrically fixed with fixing rods, the fixing rods passing through the first movable hole.

[0010] As a preferred technical solution of the miniaturized double-ridged horn antenna of this utility model, the side wall of the movable plate is provided with a second movable hole, and a connecting rod is movably inserted into the inner side of the second movable hole. The connecting rod passes through the second movable hole and is located inside the first spring.

[0011] As a preferred technical solution of the miniaturized double-ridged horn antenna of this utility model, the connecting rod end is symmetrically fixed with blocking blocks, and the blocking blocks are located on both sides of the movable plate.

[0012] As a preferred technical solution of the miniaturized double-ridged horn antenna of this utility model, the inner wall of the fixing frame is symmetrically fixed with baffles, and the baffles are located on one side of the rectangular block.

[0013] As a preferred technical solution of the miniaturized double-ridged horn antenna of this utility model, a support plate is symmetrically fixed on one side of the outer wall of the rectangular frame, and a mounting plate is fixed at one end of the support plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The antenna body of this invention is installed by a rectangular block that is movably inserted into the inner side of a rectangular frame. The rectangular block has symmetrically arranged limiting grooves on its sidewalls. Limiting rods on the sidewalls of the movable plates on both sides of the rectangular frame are movably inserted into the limiting grooves to fix the antenna body. A first spring applies elastic tension to the two movable plates, preventing them from accidentally moving to the sides and thus increasing stability. By pushing the push-pull block, the second spring is compressed, causing the rectangular rod to move. The rectangular rod then moves the trapezoidal plate, causing the vertical plate at the end of the movable plate to contact the inclined surface of the trapezoidal plate. The trapezoidal plate pushes the two vertical plates to the sides, causing the two movable plates to move to the sides. The first spring is stretched, and the limiting rods move out of the limiting grooves, allowing the rectangular block to be removed from the inner side of the rectangular frame, completing the disassembly of the antenna body. This solution enables rapid disassembly of the antenna body, making it convenient for use in locations requiring frequent disassembly and assembly, and also facilitating fault repair of the antenna body, improving maintenance efficiency.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 1-5 As shown, this utility model provides the following technical solution: a miniaturized dual-ridge horn antenna, including a rectangular frame 1, with a support plate 11 symmetrically fixed on one outer wall of the rectangular frame 1 to support and fix the rectangular frame 1. A mounting plate 12 is fixed to one end of the support plate 11 for mounting and fixing the rectangular frame 1. The side wall of the mounting plate 12 is provided with four mounting holes 121. Screws can be inserted into the inside of the mounting holes 121 to fix the mounting plate 12 in the corresponding position, thereby fixing the rectangular frame 1. After that, there is no need for repeated disassembly and assembly; only the antenna body 2 needs to be disassembled.

[0026] Reference Figure 1 , Figure 2 and Figure 4As shown, specifically, an antenna body 2 is movably inserted into the inner side of the rectangular frame 1 (the antenna body 2 is existing technology; its specific operation and principle can be referred to in the existing technology of small double-ridged horn antennas, used for long-distance signal transmission, therefore it is not described in detail here). A rectangular block 21 is fixed to one end of the antenna body 2 for mounting and fixing the antenna body 2. The rectangular block 21 is movably inserted into the inner side of the rectangular frame 1. The side wall of the rectangular block 21 is symmetrically provided with limiting grooves 211 for limiting the rectangular block 21. The outer wall of the rectangular frame 1 is symmetrically provided with through holes 19 for inserting limiting rods 132. The through holes 19 are connected to the inner side of the rectangular frame 1. The outer side of the rectangular frame 1 is symmetrically provided with movable plates 13, which can drive the limiting rods 132 to move. A limiting rod 132 is fixed to one side wall of the movable plate 13 to fix the rectangular block 21. The limiting rod 132 passes through the through hole 19. One end of the limiting rod 132 is movably inserted into the inner side of the limiting groove 211. One end of the movable plate 13 is fixed with a vertical plate 131 for moving the movable plate 13. A first spring 14 is provided on one side of the rectangular frame 1. The end of the first spring 14 is fixed to the side wall of the movable plate 13 to ensure that the limiting rod 132 will not accidentally move out of the inner side of the limiting groove 211. In this solution, the antenna body 2 is installed and fixed by movably inserting the rectangular block 21 into the inner side of the rectangular frame 1 and inserting the two limiting rods 132 into the inner side of the two limiting grooves 211 respectively. By moving the two movable plates 13 to the sides respectively, the first spring 14 is stretched, which can drive the two limiting rods 132 to disengage from the inner side of the two limiting grooves 211 respectively, so that the rectangular block 21 can be moved out of the inner side of the rectangular frame 1, and the antenna body 2 can be disassembled. The operation is simple and the antenna body 2 can be quickly disassembled when needed. Example

[0027] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, specifically, a fixing frame 17 is fixed to one side wall of the rectangular frame 1 to support the trapezoidal plate 18. The fixing frame 17 is located outside the first spring 14. A rectangular hole 171 is provided in the middle of the outer wall of one side of the fixing frame 17 for connecting the rectangular rod 181. The rectangular hole 171 is through the inner side of the fixing frame 17. The trapezoidal plate 18 is provided on the inner side of the fixing frame 17, which can push the two vertical plates 131 to move to both sides. The trapezoidal plate 18 is located on one side of the vertical plate 131. A rectangular rod 181 is fixed in the middle of one side wall of the trapezoidal plate 18 for supporting and fixing the trapezoidal plate 18 and driving the trapezoidal plate 18 to move. The rectangular rod 181 passes through the rectangular hole 171. A push-pull block 182 is fixed to one end of the rectangular rod 181 for pushing the rectangular rod 181 to move. A second spring 183 is fixed to one side wall of the push-pull block 182. The elastic force of the second spring 183 can keep the trapezoidal plate. Normally, the rectangular rod 18 does not contact the vertical plate 131. The second spring 183 is sleeved on the outside of the rectangular rod 181. One end of the second spring 183 is fixed to the outer wall of the fixing frame 17. The inner wall of the fixing frame 17 is symmetrically fixed with baffles 172. The baffles 172 are located on one side of the rectangular block 21 and block the rectangular block 21 to prevent it from moving excessively. In this solution, the second spring 183 can be compressed by pushing the push-pull block 182, which drives the rectangular rod 181 to move. The rectangular rod 181 drives the trapezoidal plate 18 to move. The two inclined surfaces of the trapezoidal plate 18 contact the ends of the two vertical plates 131, which can push the two vertical plates 131 to move to both sides. This causes the two movable plates 13 to drive the two limiting rods 132 to move, so that the limiting rods 132 move out of the inner side of the limiting groove 211, thereby quickly and conveniently disassembling the antenna body 2 and improving the efficiency of disassembly and maintenance. Example

[0028] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 4 As shown, specifically, the movable plate 13 has a first moving hole 133 on its side wall for moving the movable plate 13 outside the fixed rod 16. The first moving hole 133 is located on one side of the limiting rod 132. Fixed rods 16 are symmetrically fixed on the outer wall of the rectangular frame 1 to prevent the movable plate 13 from rotating. The fixed rods 16 pass through the first moving hole 133. The movable plate 13 has a second moving hole 134 on its side wall for moving the connecting rod 15. The connecting rod 15 is movably inserted into the inner side of the second moving hole 134 to maintain the vertical state of the first spring 14. The connecting rod 15 passes through the second moving hole 134 and is located inside the first spring 14. The end of the connecting rod 15 is symmetrically fixed with a blocking block 151 to prevent the connecting rod 15 from disengaging from the second moving hole 134 and the inside of the first spring 14. The blocking block 151 is located on both sides of the movable plate 13. In this solution, the rotation of the movable plate 13 is restricted by inserting the fixing rod 16 into the inside of the first moving hole 133. By having the connecting rod 15 located inside the first spring 14, the vertical state of the first spring 14 is maintained, which can effectively improve the overall stability.

[0029] The working principle and usage process of this utility model:

[0030] In use, place the mounting plate 12 in a suitable position and fix it with screws through the mounting holes 121. After that, there is no need to disassemble it. The antenna body 2 is connected to the inside of the rectangular frame 1 by the rectangular block 21. The two limiting rods 132 are inserted into the inside of the two limiting slots 211 to fix the antenna body 2. When the antenna body 2 malfunctions or needs to be disassembled for other reasons, push the push-pull block 182. The push-pull block 182 moves and compresses the second spring 183, which drives the rectangular rod 181 to move. The rectangular rod 181 drives the trapezoidal plate 18 to move closer to the two vertical plates 131. The ends of the two vertical plates 131 contact the inclined surfaces on both sides of the trapezoidal plate 18. The trapezoidal plate 18 pushes the two vertical plates 131 to move to both sides respectively, which drives the two movable plates 13 to move to both sides respectively. This causes the two limiting rods 132 to move out of the inside of the two limiting slots 211, and the rectangular block 21 can be removed from the inside of the rectangular frame 1, thus completing the disassembly of the antenna body 2.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
