Description

Technical Field

[0001] This utility model relates to the field of signal generator support frame technology, and in particular to a support frame for a radio frequency signal generator. Background Technology

[0002] Radio frequency (RF) signal generators are test instruments used to generate high-frequency electrical signals and are widely used in the research and testing of electronic equipment such as communication and radar. Mounting them on a support frame ensures stable operation, prevents vibration from interfering with signal accuracy, optimizes heat dissipation to prevent overheating, facilitates cable management and height adjustment to adapt to different testing scenarios, and improves operational convenience and testing reliability. Therefore, a support frame for RF signal generators is required when installing them.

[0003] According to the Chinese patent "An installation and fixing assembly for a multi-channel broadband radio frequency signal generator" authorized announcement number "CN214369110U", this utility model installs a sliding mounting base on a fixed base and fixes the mounting base with adjusting bolts. The height of the mounting base can be adjusted according to the operation site. By setting an adjustable connecting plate, different types of signal generators can be installed, which improves the applicability of the device and expands the scope of application of the device.

[0004] Although the aforementioned application allows the height of the signal generator to be adjusted by sliding the mounting base on the fixed base, the mounting base of the device can only slide up and down on the surface of the fixed base. When it is fixed, the fixed base is also fixed, which results in the angle of the signal generator being fixed and unable to be adjusted horizontally.

[0005] Therefore, a support frame for a radio frequency signal generator is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a support frame for a radio frequency signal generator to solve the above-mentioned problems, thereby improving the inability to adjust the horizontal angle of the signal generator.

[0007] The present invention achieves the above objectives through the following technical solution: a support frame for a radio frequency signal generator, comprising: a column and a housing, wherein a protective shell is fixedly connected to the top of the housing, and a lifting assembly is provided between the protective shell and the column;

[0008] The adjustment mechanism includes an angle adjustment component and a fixed adjustment component. The surface of the protective shell has multiple ventilation holes, and a baffle is slidably connected to one side of the shell.

[0009] Preferably, the lifting assembly includes a threaded rod rotatably connected to the inner wall of the column, a lifting rod slidably connected to the inner wall of the column, one end of the lifting rod being disposed on the surface of the threaded rod, and a first motor being fixedly connected to the top end of the column. The drive end of the first motor penetrates the column and is fixedly connected to the top end of the threaded rod. Adjust the height of the signal generator.

[0010] Preferably, the angle adjustment assembly includes a rotating rod fixedly connected to the surface of the protective shell, the top end of the rotating rod being rotatably connected to a lifting rod, and a first gear fixedly connected to the surface of the rotating rod. This allows for horizontal angle adjustment of the signal generator.

[0011] Preferably, a second motor is fixedly connected to the surface of the lifting rod, and a second gear is fixedly connected to the drive end of the second motor, with the first gear and the second gear meshing with each other.

[0012] Preferably, the fixing and adjusting assembly includes sliding plates slidably connected to the inner walls of both sides of the housing, and springs are fixedly connected to both ends of the inner walls of the housing and the sliding plates. This limits the movement of both ends of the signal generator.

[0013] Preferably, the fixing and adjusting assembly includes a bidirectional lead screw laterally rotatably connected inside the housing. Two locking blocks are provided on the surface of the bidirectional lead screw. A handle is rotatably connected to the surface of the housing, penetrating the housing and fixedly connected to one end of the bidirectional lead screw. This limits the movement of both sides of the signal generator.

[0014] Preferably, the bottom of the housing is provided with multiple cooling fans, and a dustproof mesh fixedly connected to the inner bottom wall of the housing is provided above the cooling fans. This provides heat dissipation for the signal generator.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting the angle adjustment component, the internal oscillator and amplifier can be ensured to be in the ideal working position, reducing the impact of mechanical stress on frequency stability. At the same time, in multi-instrument joint testing scenarios, the horizontal adjustment function keeps the device interface axially aligned with other test instruments, reducing the risk of impedance mismatch caused by lateral stress of the connector, and improving the versatility of the signal generator's application scenarios.

[0017] 2. By setting a fixed adjustment component, the distance between the two clamping blocks can be adjusted by a two-way screw to apply pressure and clamp the two sides of the signal generator of different sizes to suit different signal generators. At the same time, the slider, in combination with the pressure of the spring and the baffle, limits the two ends of the signal generator, increasing its stability on the support frame.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-4 As shown, a support frame for a radio frequency signal generator includes: a column 100, a housing 300, a protective shell 500 fixedly connected to the top of the housing 300, and a lifting assembly 200 provided between the protective shell 500 and the column 100.

[0025] The adjustment mechanism 400 includes an angle adjustment component 410 and a fixed adjustment component 420. The surface of the protective shell 500 is provided with multiple ventilation holes 510, and a baffle 310 is slidably connected to one side of the shell 300.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, the lifting assembly 200 includes a threaded rod 220 rotatably connected to the inner wall of the column 100, a lifting rod 230 slidably connected to the inner wall of the column 100, one end of the lifting rod 230 being disposed on the surface of the threaded rod 220, a first motor 210 being fixedly connected to the top of the column 100, the drive end of the first motor 210 penetrating into the column 100 and fixedly connected to the top of the threaded rod 220, and the angle adjustment assembly 410 includes a rotating rod 411 fixedly connected to the surface of the protective shell 500, the top of the rotating rod 411 being rotatably connected to the lifting rod 230, a first gear 412 being fixedly connected to the surface of the rotating rod 411, a second motor 414 being fixedly connected to the surface of the lifting rod 230, and a second gear 413 being fixedly connected to the drive end of the second motor 414, the first gear 412 and the second gear 413 meshing with each other.

[0027] In this embodiment, the first motor 210 rotates at 60 RPM, and the second motor 414 rotates at 15 RPM. When the lifting rod 230 needs to be raised, the first motor 210 is started and rotated clockwise, causing the threaded rod 220 to rotate clockwise, thereby raising the lifting rod 230. When the lifting rod 230 is lowered, the reverse is true. At the same time, when the rotating rod 411 needs to be rotated clockwise, the second motor 414 needs to be started counterclockwise. The second motor 414 drives the second gear 413 to rotate counterclockwise, and the counterclockwise rotation of the second gear 413 drives the first gear 412 to rotate clockwise, thereby causing the rotating rod 411 to drive the housing 300 to rotate clockwise, thus allowing the signal generator to be adjusted clockwise. If the signal generator needs to be adjusted counterclockwise, the second motor 414 needs to be started in the opposite direction, and so on.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the fixed adjustment assembly 420 includes a sliding plate 421 slidably connected to the inner walls of both sides of the housing 300. Springs 422 are fixedly connected to both sides of the inner walls of the housing 300 and both ends of the sliding plate 421. The fixed adjustment assembly 420 includes a bidirectional lead screw 424 rotatably connected to the inside of the housing 300. Two locking blocks 423 are provided on the surface of the bidirectional lead screw 424. A handle 425 is rotatably connected to the surface of the housing 300. The handle 425 passes through the housing 300 and is fixedly connected to one end of the bidirectional lead screw 424. Multiple cooling fans 431 are provided at the bottom of the housing 300. A dustproof net 430 is fixedly connected to the inner bottom wall of the housing 300 above the cooling fans 431.

[0029] In this embodiment, the two sides of the slide plate 421 are slidably connected to the slide grooves opened on the inner walls of the two sides of the outer shell 300. The slide grooves are provided with slide rods fixedly connected to the inner walls of both ends of the outer shell 300. The slide rods pass through the slide plate 421, and the spring 422 is sleeved on the surface of the slide rods. After the signal generator is adjusted to the preset position, the signal generator is started and the cooling fan 431 is started at the same time to dissipate heat from the cavity formed by the outer shell 300 and the protective shell 500 to prevent the temperature of the signal generator from getting too high.

[0030] When using this utility model, the column 100 needs to be fixed in the preset position through the positioning holes on both sides first. Then, the signal generator is placed inside the housing 300. Before putting the signal generator into the housing 300, the baffle 310 needs to be slid up and removed. Then, the signal generator is inserted from the front end of the housing 300. During this process, the signal generator will push the slider to slide continuously into the housing 300, while stretching the springs 422 on both sides of the housing 300. When the signal generator is fully inside the housing 300, the baffle 310 is reset to limit the two ends of the signal generator. Then, the handle 425 on the side of the housing 300 is rotated. The handle 425 drives the bidirectional screw 424 to rotate, causing the two locking blocks 423 to move towards the middle at the same time until they fit with the signal generator, and pressure is applied to limit the two sides.

[0031] After the signal generator is fixed inside the housing 300, the first motor 210 is started, and the rotation of the first motor 210 drives the threaded rod 220 to rotate, thereby raising the lifting rod 230. When the signal generator rises to the preset position, the angle of the signal generator is adjusted according to the working requirements. The second motor 414 is started, and the rotation drives the second gear 413 to rotate, which in turn drives the first gear 412 to rotate, thereby rotating the rotating rod 411. After the signal generator is adjusted to the appropriate angle, the first motor 210 is turned off.

[0032] It should be noted that the first motor 210, the second motor 414, the threaded rod 220, and the bidirectional lead screw 424 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the first motor 210, the second motor 414, and the cooling fan 431 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
