Description

Technical Field

[0001] The utility model relates to the technical field of satellite antennas, in particular to a rotating device for satellite antennas. Background Art

[0002] The satellite antenna is composed of a metal parabola, a high-frequency head, and a feed. When the satellite antenna is in operation, the satellite signal is reflected by the metal parabola of the satellite antenna to the feed and high-frequency head on the front end, thereby collecting weak signals from synchronous satellites. Synchronous satellites are generally above the equator, and my country is in the northern hemisphere, so my country's general signal antennas are facing south or slightly south.

[0003] When the satellite antenna is debugged in the later stage, it is necessary to adjust the direction of the antenna. For example, in the patent application with publication number CN 218548799 U in the prior art, the base is located below the satellite antenna body, and the bottom of the satellite antenna body is connected to a connecting body, a first rotating groove is provided on the base, and slots are provided at equal intervals on the connecting body. A third groove is provided on one side of the outer side of the base. The utility model is provided with a first rotating groove, a second rotating groove and a rotating shaft, etc. When adjusting the angle of the metal parabola of the satellite antenna, the rotating shaft is driven by the handle to rotate in the second rotating groove, and the rotating shaft drives the gear to rotate. Since the gear and the slot are engaged and connected, the gear drives the connecting body to rotate inside the first rotating groove, thereby achieving the purpose of adjusting the angle, and solving the problem that the satellite antenna cannot turn freely when debugging the angle of the metal parabola.

[0004] However, when the device is in use, after the antenna is adjusted to a suitable angle, due to the lack of a limit assembly, the angle direction of the antenna may change during subsequent use, thus affecting the normal use of the antenna.

[0005] Therefore, it is necessary to provide a rotating device for a satellite antenna to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0027] First embodiment

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic structural diagram of a first embodiment of a rotating device for a satellite antenna provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the cross-sectional structure of the fixed frame shown; Figure 3 for Figure 1 The enlarged schematic diagram of part A is shown. A rotating device for a satellite antenna comprises: a mounting plate 1;

[0029] A fixing frame 2, wherein the fixing frame 2 is fixedly mounted on the top of the mounting plate 1;

[0030] A mounting rod 3, the mounting rod 3 being rotatably connected to the interior of the top of the fixing frame 2, an antenna 31 being fixedly mounted on one end of the mounting rod 3, and a first gear 32 being fixedly mounted on the outer side of the mounting rod 3;

[0031] A rotating disk 4, wherein the rotating disk 4 is arranged at the top of the fixed frame 2, a rotating shaft 41 is fixedly installed at the bottom of the rotating disk 4, the bottom of the rotating shaft 41 is rotatably connected to the bottom of the inner side of the fixed frame 2, a second tooth plate 42 is fixedly installed on the outer side of the rotating shaft 41, a through hole 48 is opened inside the rotating disk 4, a sliding rod 43 is slidably connected to the inner side of the through hole 48, a rotating handle 44 is rotatably connected to the top of the sliding rod 43, a limiting plate 46 is fixedly installed at the bottom of the sliding rod 43, a spring 45 is sleeved on the outer side of the sliding rod 43, and a tooth plate 47 is fixedly installed at the bottom of the limiting plate 46;

[0032] A groove 21 is provided at the top of the fixing frame 2 , and a gear ring 22 is fixedly mounted at the bottom of the inner side surface of the groove 21 .

[0033] The groove 21 is disposed on the outer side of the rotating shaft 41 , and the first gear 32 and the second gear plate 42 are meshed with each other.

[0034] A bottom plate 33 is fixedly mounted on the bottom of the mounting rod 3 , and rollers 34 are fixedly mounted on both ends of the bottom of the bottom plate 33 .

[0035] The spring 45 is disposed between the rotating disk 4 and the limiting plate 46 .

[0036] The top of the mounting plate 1 is provided with a plurality of mounting holes.

[0037] Through the plurality of mounting holes opened on the mounting plate 1, it is convenient for the user to install the mounting plate 1 and the fixing frame 2 on the ground;

[0038] By installing the bottom plate 33 and the roller 34 at the bottom of the mounting rod 3, the bottom of the roller 34 will roll at the bottom of the inner side of the fixing frame 2 during use, thereby increasing the stability of the mounting rod 3 in rotation;

[0039] The elasticity of the spring 45 always pushes the limit plate 46 and the tooth plate 47 downward when in use, so that the tooth plate 47 and the gear ring 22 are meshed.

[0040] The working principle of a rotating device for a satellite antenna provided by the utility model is as follows:

[0041] When the user needs to adjust the direction of the antenna 31 during use, the user first lifts the handle 44 upward, so that the handle 44 drives the sliding rod 43, the limit plate 46 and the tooth plate 47 to move upward, so that the tooth plate 47 and the gear ring 22 are separated, and then the user drives the rotating disk 4 to rotate through the handle 44, so that the rotating disk 4 drives the rotating shaft 41 to rotate, so that the rotating shaft 41 drives the second gear 42 to rotate, and then the second gear 42 and the first gear 32 are meshed, and then the mounting rod 3 is driven to rotate, so that the mounting rod 3 drives the antenna 31 to adjust the direction. After adjusting to the appropriate position, the user only needs to loosen the handle 44. At this time, the elasticity of the spring 45 will drive the limit plate 46 and the tooth plate 47 to move downward, so that the bottom of the tooth plate 47 is stuck on the top of the gear ring 22, thereby limiting the rotating disk 4 and preventing the antenna 31 from rotating during subsequent use.

[0042] Compared with the related art, the rotating device for satellite antenna provided by the utility model has the following beneficial effects:

[0043] The structures such as the rotating disk 4, the rotating shaft 41, the sliding rod 43, the rotating handle 44, the spring 45, the limiting plate 46, the tooth plate 47, the groove 21 and the gear ring 22 cooperate with each other. When in use, the elasticity of the spring 45 drives the limiting plate 46 and the tooth plate 47 to move downward, so that the tooth plate 47 and the gear ring 22 are engaged. In this way, the antenna 31 can be limited to prevent the antenna 31 from rotating during subsequent use, which affects the normal use of the antenna 31.

[0046] Specifically, the second embodiment of the present application provides a rotating device for a satellite antenna that is different in that, in the rotating device for a satellite antenna, both sides of the inner side surface of the through hole 48 are fixedly mounted with limiting plates 51 .

[0047] Limiting grooves 5 are provided on both sides of the sliding rod 43 , and the limiting plates 51 are slidably connected to the inner side surfaces of the limiting grooves 5 .

[0048] The working principle of a rotating device for a satellite antenna provided by the utility model is as follows:

[0049] When in use, the slide bar 43 moves up and down, thereby driving the limiting groove 5 to slide on the outer side of the limiting plate 51, thereby limiting the slide bar 43 and preventing the slide bar 43 from rotating.

[0050] Compared with the related art, the rotating device for satellite antenna provided by the utility model has the following beneficial effects:

[0051] By the limiting plate 51 sliding on the inner side of the limiting groove 5 , the slide bar 43 can be limited to prevent the slide bar 43 from rotating, thereby preventing the angle of the tooth plate 47 from changing.
