[0002] A microwave power amplifier is a device used to amplify radio frequency (RF) and microwave signals. It is commonly used in wireless communication systems, radar systems, and other RF applications. These amplifiers can amplify input microwave signals to higher power levels to provide the required power levels when transmitting and processing signals in communications, radar, or other RF systems.

[0003] When a microwave power amplifier is subjected to a water cooling test, the power amplifier is installed in a test fixture and connected to a water cooling system to ensure that the coolant can effectively flow through the heat dissipation part of the power amplifier. When the microwave amplifier is tested, the existing fixture can effectively clamp and set up the microwave power amplifier, but amplifiers of different specifications and sizes have different positions of interfaces with various lines at both ends and the positions of connection ports required for water cooling pipelines. Therefore, when the existing fixture is clamped, it is easy for the fixture to limit the interfaces at both ends of a certain type of microwave power amplifier, which is not conducive to water cooling tests on microwave power amplifiers.

DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 4The utility model provides the following technical solutions: it includes a bottom plate 1, a frame plate 11 is connected to the bottom plate 1, a mounting plate 12 is hinged between the frame plates 11, two sliding rods 2 are slidably connected to the mounting plate 12, two fixing rods 21 are fixedly connected to the top of the sliding rod 2, a cross bar 221 is fixedly connected between the fixing rods 21, two vertical rods 22 are slidably connected to the top of the sliding rod 2, the cross bar 221 penetrates the vertical rod 22, an adjusting groove 23 is opened on one side of the vertical rod 22, an upper clamping rod 24 is slidably connected to the inner wall of the adjusting groove 23, a limiting rod 25 for limiting the upper clamping rod 24 is fixedly connected between the upper clamping rod 24 and the inner wall of the adjusting groove 23, a lower clamping rod 242 is fixedly connected to one side of the sliding rod 2, and the lower clamping rod 242 is located below the upper clamping rod 24.

[0018] In this embodiment: the bottom plate 1 is a carrier of the bearing device, and the frame plate 11 fixedly connected to the bottom plate 1 is used to install the mounting plate 12, so that the mounting plate 12 can be hinged between the two frame plates 11, so that the mounting plate 12 can be mounted between the frame plates 11, so that the clamping assembly above the mounting plate 12 can clamp and support the microwave power amplifier, and the mounting plate 12 is hinged between the frame plates 11, so that when the microwave power amplifier is installed or removed, the mounting plate 12 can be rotated between the frame plates 11, so that the device can adjust the angle of the clamping member, which is convenient for clamping and installing the microwave power amplifier. Before the microwave amplifier is clamped, the two slide bars 2 can slide on the mounting plate 12, so that the spacing between the slide bars 2 can be adjusted, so that the lower clamping bar 242 fixedly connected to one side of the vertical pole 22 can support and install the microwave power amplifier. By adjusting the spacing of the slide bars 2, the lower clamping bar 242 is supported under the microwave power amplifier. At the same time, when the microwave power amplifier is clamped and installed, in order to prevent the vertical pole 22 from limiting the line connection interface at both ends of the microwave power amplifier and the water-cooling heat dissipation device connection pipeline port, the vertical pole 22 can slide between the two fixed poles 21, and the vertical pole 22 is fixed. The limit of the cross bar 221 fixedly connected between the rods 21 enables the vertical rod 22 to ensure that it is vertically mounted on the sliding rod 2 while being able to slide and adjust the position of the vertical rod 22 on the sliding rod 2, so that the device can misalign the vertical rod 22 with the interface position according to the position of each interface at both ends of the microwave power amplifier, so as to avoid affecting the connection of the line, thereby affecting the test work of the microwave power amplifier after it is connected to the water cooling device. At the same time, the device can adjust the sliding rod 2 to match the microwave power amplifier according to the different models and sizes of the microwave power amplifier, and adjust the vertical rod 22 to the interface misalignment connected to the pipeline line at will. The position of the device makes it convenient for the staff to perform water-cooling connection tests on the microwave power amplifier, avoiding affecting the connection of the lines or water-cooling pipelines when testing microwave power amplifiers of different models. When the microwave power amplifier is supported on the lower clamping rod 242, the upper clamping rod 24 can be supported by the spring 251 fixedly connected to the inner wall of the adjustment groove 23 opened on one side of the slide bar 2, so that the upper clamping rod 24 can cooperate with the lower clamping rod 242 under the support of the spring 251, so that the microwave power amplifier is clamped, ensuring that it is clamped and set in position for water-cooling testing.

[0019] A rotating rod 121 is fixedly connected to the connection between the mounting plate 12 and the frame plate 11, and the mounting plate 12 is hinged to the frame plate 11 through the rotating rod 121. Matching limiting holes 13 are provided on the mounting plate 12 and the frame plate 11; the mounting plate 12 is installed on the frame plate 11 through the rotating rods 121 fixedly connected on both sides thereof, so that the mounting plate 12 can be hinged and rotated between the frame plates 11, so that the mounting plate 12 can be adjusted to an angle that is convenient for the staff to install the microwave power amplifier, and at the same time, it is convenient to connect the lines and pipelines on the microwave power amplifier. The limiting holes 13 provided on the mounting plate 12 and the frame plate 11 can limit the mounting plate 12 and the frame plate 11 relative to each other vertically by means of latches or the like.

[0020] A slide groove 222 is provided at the top of the slide rod 2, and a limit block 223 matching the slide groove 222 is fixedly connected to the bottom end of the fixed rod 21; the slide groove 222 provided at the top of the slide rod 2 is used to limit the limit block 223 fixedly connected to the bottom end of the vertical pole 22, ensuring that the vertical pole 22 slides vertically on the slide rod 2, so that when the vertical pole 22 is adjusted in position, its supporting force for the microwave power amplifier is ensured.

[0021] Two mounting blocks 3 are fixedly connected to the top of the slide bar 2, and two screw rods 31 are rotatably connected between the mounting blocks 3, and the screw rods 31 are threadedly connected to the slide bar 2. Four fixing blocks 32 are fixedly connected to the top of the slide bar 2, and a support rod 33 is fixedly connected between the two fixing blocks 32, and the support rod 33 passes through the slide bar 2; the two mounting blocks 3 fixedly connected to the top of the slide bar 2 are used to install the screw rod 31, which is rotated between the mounting blocks 3 by the screw rod 31, and the screw rod 31 is threadedly connected to the slide bar 2, so that when rotating on the screw rod 31, the slide bar 2 can be driven to adjust its position synchronously, so that the spacing between the two slide bars 2 can be adjusted, and the fixing blocks 32 are used to install the support rods 33, which pass through the slide bar 2 through the support rods 33, so that the two support rods 33 can limit the two ends of the slide bar 2, so that the slide bar 2 can slide horizontally.

[0022] One end of the upper clamping rod 24 is fixedly connected to a connecting block 241 that matches the adjusting groove 23, and a limiting rod 25 passes through the connecting block 241, and a spring 251 is sleeved on the outer wall of the limiting rod 25; the connecting block 241 to which one end of the upper clamping rod 24 is fixedly connected is used to be located on the inner wall of the adjusting groove 23, and the limiting rod 25 can pass through the connecting block 241, so that the connecting block 241 can be limited by the limiting rod 25, and at the same time can be supported by the spring 251, so that the upper clamping rod 24 will not be separated from the adjusting groove 23.

[0023] The working principle and use process of the utility model are as follows: before clamping the microwave amplifier, the spacing between the slide bars 2 can be adjusted to a position that matches the size of the microwave power amplifier, and then according to the connection positions of the various lines and pipelines on the microwave power amplifier, the position of the vertical pole 22 between the fixed poles 21 can be adjusted to avoid affecting the microwave power amplifier from being connected to the water cooling device and then being tested. When the microwave power amplifier is supported on the lower clamping rod 242, the vertical pole 22 can be displaced from the fixed pole 21. At this time, the microwave power amplifier can be adjusted through the adjustment slot 23 opened on one side of the slide bar 2. The spring 251 fixedly connected to the wall supports the upper clamping rod 24, so that the upper clamping rod 24 can cooperate with the lower clamping rod 242 under the support of the spring 251, so that the microwave power amplifier is clamped, ensuring that it is clamped and mounted in position for water cooling testing. The mounting plate 12 is then hinged between the frame plates 11, so that when the microwave power amplifier is installed or removed, the mounting plate 12 can be rotated between the frame plates 11, so that the device can adjust the angle of the clamping member, which is convenient for clamping and installing the microwave power amplifier.
