Technical Field

[0001] This utility model relates to an antenna fixing device with a mounting surface. It belongs to the field of mechanical engineering technology. Background Technology

[0002] In communication equipment testing, to achieve a specific task, it is necessary to test the payload used in the task, which usually takes the form of remote wireless testing. When building a wireless communication link, a payload needs to be set up at a remote end, and signals need to be transmitted and received using an antenna to complete tests such as information interface and antenna polarity.

[0003] All payload antennas have mounting surfaces; some use flanges, while others have mounting fixtures at the bottom. During testing, the payload antenna must be precisely aligned with the radar antenna of the communication equipment; otherwise, the test results will be uncertain. However, due to differences in payloads, the mounting methods of the antennas vary, resulting in significant differences in the dimensions of the flanges and mounting fixtures. This poses a major challenge to the installation of the payload antennas. Therefore, there is an urgent need to design a device that can easily install the payload antennas while ensuring accurate antenna alignment.

[0023] Referring to Figures 1-6, the antenna mounting device with a mounting surface adopts a "Z"-shaped structure, consisting of a base plate 1, a middle plate 2, and a fixing plate 3. The "Z"-shaped structure ensures the load antenna remains horizontal during installation, and allows for waterproofing of the load antenna using materials such as plastic bags through the gap between the middle plate 2 and the fixing plate 3.

[0024] Base plate 1: This is a rectangular plate, as shown in Figure 1. A through hole is made at a suitable location, and it is fixedly connected to the existing mounting reference surface by short bolts to ensure the stability of the entire device. Simultaneously, by loosening the bolts and rotating the entire device, the load antenna can be aligned with the communication system antenna.

[0025] Middle plate 2: It is a rectangular plate, as shown in Figure 1. It connects the base plate 1 and the fixing plate 3 together at a suitable angle, and keeps the fixing plate 3 horizontal while ensuring the function of the device.

[0026] Fixed plate 3: This is the main structure of the fixed load antenna, as shown in Figure 2. It consists of a base plate 3.1, a rear baffle 3.2, a sliding guide post 3.3, a flip-up sliding guide post 3.4, and a front baffle 3.5.

[0027] Substrate 3.1: A "T"-shaped plate, as shown in Figure 3. Sliding guide posts 3.3 are fixed to the two wings of the "T". The sliding guide posts 3.3 are used to guide the rear baffle 3.2 to move back and forth and to fix it vertically. A through slot is opened at the bottom of the "T"-shaped horizontal plate, as shown in Figure 3. This through slot is used to embed the bottom edge of the flange-type load antenna, and together with the rear baffle 3.2 and the front baffle 3.5, it plays a three-point fixing role. A flip-up sliding guide post 3.4 is arranged on each side of the through slot of the "T"-shaped horizontal plate. The flip-up sliding guide posts 3.4 are used to guide the two front baffles 3.5 to move horizontally to a suitable position, ensuring that the front baffle 3.5 and the rear baffle 3.2 can fix the flange-type load antenna. For unused flip-up sliding guide posts 3.4, their connecting blocks can be rotated toward the rear baffle 3.2 to avoid obstructing the implementation of waterproofing measures; the "T"-shaped vertical plate serves as a reference plate for fixing the RF cable of the flange-type load antenna, while also protecting the RF connector of the load antenna.

[0028] Rear baffle 3.2: It has a "7" shaped structure, as shown in Figure 4. The horizontal "7" shaped bar is used to place the fixture surface of the fixture-type payload antenna. It has 4 holes, and the payload antenna with the fixture surface can be fixed by cross binding with cloth strips, etc. The short vertical "7" shaped bar is used to fix the RF cable of the fixture-type payload antenna and also serves to protect the connector. The long vertical "7" shaped bar has an inverted "U" structure. There is a round tube at each of the two door pillars for moving back and forth on the sliding guide post 3.3. The round tubes are equipped with butterfly bolts for fixing the rear baffle 3.2. The opening of the inverted "U" structure is used for the cable of the flange-loaded payload antenna to pass through.

[0029] Sliding guide posts: These are two cylindrical structures, distributed left and right, which facilitate the back baffle 3.2 to move back and forth on them, while preventing the back baffle 3.2 from flipping over during movement.

[0030] The flip-up sliding guide post 3.4 is composed of multiple connecting blocks, as shown in Figures 5-6, and its overall structure resembles a chain. These connecting blocks not only allow the front baffle 3.5 to move on it, but also enable it to flip during waterproofing operations, ensuring that the waterproofing process is not hindered.

[0031] Front baffle 3.5: The overall structure is similar to a flag, arranged on the left and right. The square tube at the bottom is used to move left and right on the flip-sliding guide post, and the flag surface at the top is used to form a clamping device with the rear baffle to fix the flange-type load antenna.

[0032] Implementation Example 1 (Flange-type payload antenna installation, as shown in Figure 7) Connect the RF connector of the flange antenna to the cable, then place the flange in the reference plate slot of the fixed plate, ensuring that the cable lies flat on the reference plate of the fixed plate without stress; first move the front baffle to make it close to the antenna shield; then move the rear baffle to make it close to the other side of the load antenna flange, ensuring that the flange is locked between the front and rear baffles, and then lock the rear baffle; after fixing the cable, use a plastic bag to cover the fixed plate and the middle plate for waterproofing.

[0033] Implementation Example 2 (Jig-type payload antenna installation, as shown in Figure 8) Connect the RF connector cable of the tool-type payload antenna, thread a strip of cloth through the two through holes on the rear baffle, place the tool-type payload antenna on the horizontal surface of the rear baffle, thread the cloth strip diagonally through the other two through holes on the rear baffle, and then tie it tightly; after fixing the cable, use a plastic bag to cover the fixing plate and the middle plate for waterproofing.

[0034] In addition to the above embodiments, this utility model also includes other embodiments. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
