[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4, S-band all-metal load testing device, including a base plate 1, a full-metal load body 2 is provided on the outside of the base plate 1, and a fixed detection device 3 is provided on the outside of the base plate 1;

[0023] The fixed detection device 3 includes a drive motor 301, a bidirectional threaded rod 302, a roller fixing seat 303, a roller body 304, a rotating ring 305, a pressure block 306, an electric slide rail 307 and a network analyzer 308. The drive motor 301 is fixedly installed inside the base plate 1, and the bidirectional threaded rod 302 is rotatably connected inside the base plate 1. The outer surface of the bidirectional threaded rod 302 is threadedly connected to the roller fixing seat 303, and the top of the roller fixing seat 303 is fixedly installed with the roller body 304. The outer surface of the roller body 304 is movably connected with the rotating ring 305. The outside of the rotating ring 305 is provided with a pressure block 306, the top of the base plate 1 is fixedly installed with the electric slide rail 307, and the outside of the electric slide rail 307 is provided with a network analyzer 308.

[0024] Specifically, such as Figure 2 As shown, the drive motor 301 is a forward and reverse motor. A forward and reverse motor refers to a motor that can realize forward and reverse operation. The working principle of the forward and reverse motor is based on changing the phase sequence of the motor power supply to achieve a change in the rotation direction. In a three-phase asynchronous motor, the rotation direction of the motor can be changed by swapping any two phases. This operation is called commutation, which allows the motor to run in different directions as needed.

[0025] Specifically, as shown in the figure, after connecting the special connection interface of the all-metal load body 2 to the connection section of the network analyzer 308, the test software of the network analyzer 308 is started, the appropriate test mode is selected, and data collection begins. The network analyzer 308 will begin to capture and record the response data of the S-band all-metal load body 2. Using the analysis tools provided by the network analyzer 308, the captured data is analyzed to observe the amplitude, phase and other information of the S parameters to understand the performance of the S-band all-metal load body 2. The test results are recorded, including test data, charts, etc. These results can be used to evaluate whether the performance of the S-band all-metal load body 2 meets the requirements, or for subsequent optimization and improvement.

[0026] Specifically, such as Figure 2 As shown, after use, the second threaded rod is reversed to cancel the fixation of the network analyzer 308, and the network analyzer 308 can be removed separately for maintenance or repair. Then, the first threaded rod is reversed in sequence by the rotating rod to cancel the fixation of the full metal load body 2, thereby removing the full metal load body 2 from the two rotating rings 305.

[0027] During implementation, follow these steps:

[0028] 1) Turn on the drive motor 301 and use the gears and belt to simultaneously drive the two bidirectional threaded rods 302 to rotate;

[0029] 2) The rotation of the bidirectional threaded rod 302 drives the movement of the roller fixing seat 303, and then the full metal load body 2 is placed between the two rotating rings 305;

[0030] 3) The first threaded rod is then rotated in sequence by the rotating rod to cooperate with the pressing block 306 to fix the all-metal load body 2, and the rotating ring 305 and the roller body 304 drive it to rotate;

[0031] 4) Finally, open the electric slide rail 307 and move the fixed network analyzer 308 closer to the all-metal load body 2. After the two are connected, testing can be performed through the network analyzer 308.

[0032] In summary, the S-band all-metal load testing device, according to the length of the all-metal load body 2, turns on the driving motor 301 to drive the two bidirectional threaded rods 302 to rotate through gears and belts, and the rotation of the two bidirectional threaded rods 302 drives the two roller fixing seats 303 and the above components to move relative to each other. After moving to the appropriate length, the all-metal load body 2 is placed between the two rotating rings 305, and the rotating rods are inserted into the eight plug-in blocks in sequence, and the rotation of the rotating rods drives the rotation of the eight first threaded rods in sequence, and the rotation of the eight first threaded rods drives the eight pressing blocks 306 to fix the all-metal load body 2. After being fixed, when it needs to be rotated during the overall welding, the fixed full-metal load body 2 can be driven to rotate by directly rotating the rotating ring 305 in conjunction with the roller body 304, and the overall welding process can be performed on it. Then, the network analyzer 308 is placed on the top of the movable plate and fixed by rotating the second threaded rod in conjunction with the clamping plate. Then, the electric slide rail 307 is opened to drive it to move in the direction of the full-metal load body 2. Then, the special connection interface is connected to the connection end, and testing can be performed through the network analyzer 308, thereby achieving the purpose of facilitating the fixation of the full-metal load body 2 and facilitating rotation adjustment after fixation.
