Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an antenna angle adjustment device. Background Technology

[0002] In the field of wireless communication technology, particularly antenna communication technology, it is often necessary to adjust the tilt and azimuth angles of various antennas, such as large outdoor antennas, to achieve better directional signal reception and improve communication stability and signal strength. In the industry, electrically adjustable antennas are commonly used to achieve this electric adjustment of the angles of large outdoor antennas. This is achieved through a coordinated electronic control mechanism, a corresponding linkage mechanism, and an antenna mounting plate mounted on the linkage mechanism, which adjusts the angle of the antenna on the mounting plate.

[0003] The existing antenna angle adjustment mechanism has a complex overall structure, which makes antenna system installation and construction difficult and costly.

[0004] Therefore, it is necessary to provide an antenna angle adjustment device to overcome the shortcomings of the prior art. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems and provide an antenna angle adjustment device.

[0006] To achieve the objectives of this invention, the following technical solution is adopted:

[0007] An antenna angle adjustment device includes: a mast; an antenna tilt adjustment mechanism disposed on the mast; an antenna azimuth adjustment mechanism disposed on the mast and located below the antenna tilt adjustment mechanism; and an antenna mounting plate; wherein, both ends of the antenna mounting plate are rotatably connected to the antenna tilt adjustment mechanism and the antenna azimuth adjustment mechanism, respectively.

[0008] Preferably, the antenna tilt adjustment mechanism includes: a first fixed base; a first rotating base rotatably mounted on the first fixed base; a first cylinder having a first cylinder body and a first push rod retractably mounted relative to the first cylinder body; a first connecting rod; and a second connecting rod; wherein one end of the first connecting rod is rotatably connected to one end of the first rotating base, and the other end is rotatably connected to the second connecting rod; the first cylinder body is rotatably connected to the other end of the first rotating base; the first push rod is rotatably connected to the first connecting rod at a position between the two ends of the first connecting rod; and the other end of the second connecting rod is rotatably connected to one end of the antenna mounting plate.

[0009] When the first cylinder is connected to an external air source and electronic control system, it will push the first push rod out of the cylinder body. Since the end of the first push rod is rotatably connected to the two ends of the first connecting rod, the entire first cylinder rotates relative to the first rotating seat during the extension of the first push rod. At the same time, the first connecting rod also rotates relative to the first rotating seat, thereby changing the angle of the first connecting rod relative to the first rotating seat. Meanwhile, the second connecting rod also rotates relative to the first connecting rod. During the rotation of the second connecting rod, the antenna mounting plate, which is rotatably connected to the second connecting rod, also rotates relative to the second connecting rod, thereby adjusting the tilt angle of the antenna mounted on the antenna mounting plate.

[0010] Preferably, a first mounting groove is formed on one end face of the first fixing seat; the retaining rod is secured in the first mounting groove, thereby fixing the entire first fixing seat to the retaining rod.

[0011] Preferably, a first shaft hole is formed on the other end face of the first fixed seat; the first rotating seat includes a first seat body, and a first rotating shaft is provided at one end of the first seat body; the first rotating shaft is rotatably disposed in the first shaft hole, thereby realizing the relative rotation of the first rotating seat with respect to the first fixed seat.

[0012] Preferably, one end of the first connecting rod is rotatably connected to one end of the first rotating seat that forms the first rotating shaft.

[0013] Preferably, a first pivot bracket is provided at one end of the first base that is rotatably connected to the first cylinder body, and the first cylinder body is rotatably disposed within the first pivot bracket.

[0014] Preferably, to ensure the relative positional accuracy between the first push rod and the first connecting rod during the extension and retraction process, a slider can be provided on the cylinder body; and a guide groove can be formed between the two ends of the first connecting rod; the slider is slidably disposed within the guide groove. With this design, when the first push rod pushes or pulls the first connecting rod, the left-right swaying phenomenon of the first push rod during the pushing and pulling process will be greatly reduced, thereby providing a stable pushing and pulling action and enabling smoother adjustment of the antenna tilt angle.

[0015] Preferably, in order to limit the antenna tilt adjustment angle within a certain range and avoid over-adjustment that could damage the antenna tilt adjustment mechanism, a pair of sidewalls are provided on both sides of the other end of the first connecting rod and the second connecting rod that are rotatably connected, and each sidewall has an arc-shaped limiting groove; correspondingly, limiting posts are provided on both sides of the corresponding end of the second connecting rod; the corresponding limiting posts are set in the corresponding arc-shaped limiting grooves. When the limiting posts abut against the two extreme positions of the corresponding arc-shaped limiting grooves, the two connecting rods will be restricted from further rotating relative to each other, thereby protecting the corresponding components.

[0016] More preferably, the antenna azimuth adjustment mechanism includes: a second fixed base; a second rotating base rotatably disposed on the second fixed base; and a second cylinder having a second cylinder body and a second push rod retractably disposed relative to the second cylinder body; wherein the second cylinder body is rotatably disposed on the second fixed base, the second push rod is rotatably connected to one end of the second rotating base, and the other end of the second rotating base is rotatably connected to the other end of the antenna mounting plate.

[0017] After the second cylinder is connected to the external air source and electronic control system, when the second cylinder operates, it pushes the second push rod to extend from the cylinder body. Since the end of the second push rod is rotatably connected to one end of the second rotating seat, the entire second rotating seat rotates horizontally relative to the second fixed seat during the extension of the second push rod. During this rotation, since both ends of the antenna mounting plate are rotatably connected to the antenna tilt adjustment mechanism and the antenna azimuth adjustment mechanism, respectively, the antenna mounting plate and the antenna tilt adjustment mechanism rotate synchronously relative to the second fixed seat in the horizontal direction, thereby enabling adjustment of the left and right azimuth angles of the antenna mounted on the antenna mounting plate.

[0018] Preferably, a second mounting groove is formed at one end of the second fixing base; the mounting rod is secured in the second mounting groove, thereby fixing the entire second fixing base to the mounting rod. When it is necessary to adjust the position of the entire antenna azimuth adjustment mechanism on the mounting rod, it is only necessary to loosen the connection between the two. After the antenna azimuth adjustment mechanism is adjusted to the appropriate position, the two are tightened together again.

[0019] Preferably, the device further includes a scale that is parallel to the mast and passes through the first and second fixed bases. The height of the antenna azimuth adjustment mechanism relative to the mast can be adjusted by means of the scale on the scale.

[0020] Preferably, the second fixed seat is rotatably configured such that a second shaft hole is provided at one end of the second rotating seat; a second rotating shaft is provided on the second rotating seat at a position corresponding to the second shaft hole; the second rotating shaft is rotatably disposed in the second shaft hole, thereby realizing the relative rotation of the second rotating seat with respect to the second fixed seat.

[0021] More preferably, a second pivot bracket is provided at one end of the second rotating seat where the second mounting groove is formed, and a part of the second cylinder body is rotatably disposed in the second pivot bracket, thereby realizing the rotatable placement of the second cylinder body on the second fixed seat.

[0022] Preferably, the second rotating seat has a pair of lugs at the end where the second rotating shaft is located, and the second push rod is rotatably disposed in the pair of lugs, thereby realizing the rotational connection between the second push rod and one end of the second rotating seat.

[0023] Compared with the prior art, the advantages of the present invention are as follows:

[0024] Because it includes an antenna tilt adjustment mechanism and an antenna azimuth adjustment mechanism that are rotatably connected to the antenna mounting plate, the antenna tilt angle can be adjusted via the tilt adjustment mechanism, and the antenna azimuth angle can be adjusted via the azimuth adjustment mechanism. Therefore, the antenna tilt angle and azimuth angle can be easily adjusted. Furthermore, the antenna tilt adjustment mechanism and antenna azimuth adjustment mechanism provided by this invention adopt a simple multi-link structure, resulting in a simple, low-cost, and stable antenna angle adjustment device.

[0034] According to one embodiment of the present invention, in combination Figure 1-4 An antenna angle adjustment device 100 includes:

[0035] 10 poles;

[0036] Antenna tilt adjustment mechanism 20 is provided on the mast 10;

[0037] Antenna azimuth adjustment mechanism 30 is mounted on the mast 10 and located below the antenna tilt adjustment mechanism 20; and

[0038] Antenna mounting plate 40; wherein,

[0039] The two ends of the antenna mounting plate 40 are rotatably connected to the antenna tilt adjustment mechanism 20 and the antenna azimuth adjustment mechanism 30, respectively.

[0040] In one embodiment of the present invention, the antenna tilt adjustment mechanism 20 includes:

[0041] First fixed seat 22;

[0042] The first rotating seat 24, which is rotatably mounted on the first fixed seat 22;

[0043] The first cylinder 26 has a first cylinder body 262 and a first push rod 264 that can be telescopically disposed relative to the first cylinder body 262;

[0044] First link 28; and

[0045] Second link 21; where...

[0046] One end of the first connecting rod 28 is rotatably connected to one end of the first rotating seat 24, and the other end is rotatably connected to the second connecting rod 21; the first cylinder body 262 is rotatably connected to the other end of the first rotating seat 24; the first push rod 264 is rotatably connected to the first connecting rod 28 at a position between the two ends of the first connecting rod 28; and the other end of the second connecting rod 21 is rotatably connected to one end of the antenna mounting plate 40.

[0047] After the first cylinder 26 is connected to the external air source and electronic control system, when the first cylinder 26 is working, it will push the first push rod 264 to extend from the first cylinder body 262. Since the end of the first push rod 264 is rotatably connected to the two ends of the first connecting rod 28, the entire first cylinder 26 rotates relative to the first rotating seat 24 during the extension of the first push rod 264. At the same time, the first connecting rod 28 also rotates relative to the first rotating seat 24, thereby changing the angle of the first connecting rod 28 relative to the first rotating seat 24. Meanwhile, the second connecting rod 21 also rotates relative to the first connecting rod 28. During the rotation of the second connecting rod 21, the antenna mounting plate 40, which is rotatably connected to the second connecting rod 21, also rotates relative to the second connecting rod 21, thereby causing the tilt angle of the antenna mounted on the antenna mounting plate 40 to be adjusted.

[0048] Preferably, a first mounting groove 222 is formed on one end face of the first fixing seat 22; the rod 10 is fixed in the first mounting groove 222, thereby fixing the first fixing seat 22 to the rod 10.

[0049] Preferably, a first shaft hole 224 is provided on the other end face of the first fixed seat 22; the first rotating seat 24 includes a first seat body 242, and a first rotating shaft 2426 is provided at one end of the first seat body 242; the first rotating shaft 2426 is rotatably disposed in the first shaft hole 224, thereby realizing the relative rotation of the first rotating seat 24 with respect to the first fixed seat 22.

[0050] Preferably, one end of the first connecting rod 28 is rotatably connected to one end of the first rotating seat 24 that forms the first rotating shaft 2426.

[0051] Preferably, a first pivot bracket 2422 is provided at one end of the first base 242 that is rotatably connected to the first cylinder body 262, and the first cylinder body 262 is rotatably disposed within the first pivot bracket 2422.

[0052] Preferably, to ensure the relative positional accuracy between the first push rod 264 and the first connecting rod 28 during the extension and retraction process, a slider 266 can be provided on the cylinder body 262; and a guide groove 282 is formed between the two ends of the first connecting rod 28; the slider 266 is slidably disposed in the guide groove 282. With this design, when the first push rod 264 pushes or pulls the first connecting rod 28, the left-right swaying phenomenon of the first push rod 264 during the push-pull process will be greatly reduced, thereby providing a stable push-pull action and enabling more smooth adjustment of the antenna tilt angle.

[0053] Preferably, in order to limit the antenna tilt angle within a certain range and avoid over-adjustment that could damage the antenna tilt adjustment mechanism 20, a pair of sidewalls 284 are provided on both sides of the other end of the first connecting rod 28 and the second connecting rod 21 that are rotatably connected. Each sidewall 284 has an arc-shaped limiting groove 2842. Correspondingly, limiting posts 212 are provided on both sides of the corresponding end of the second connecting rod 21. The corresponding limiting posts 212 are set in the corresponding arc-shaped limiting grooves 2842. When the limiting posts 212 abut against the two extreme positions of the corresponding arc-shaped limiting grooves 2842, the two connecting rods will be restricted from further rotating relative to each other, thereby protecting the corresponding components.

[0054] In one embodiment of the present invention, the antenna azimuth adjustment mechanism 30 includes:

[0055] Second fixing seat 32;

[0056] The second rotating seat 34 is rotatably mounted on the second fixed seat 32; and

[0057] The second cylinder 36 has a second cylinder body 362 and a second push rod 364 that is retractable relative to the second cylinder body 362; wherein...

[0058] The second cylinder body 362 is rotatably mounted on the second fixed seat 32, the second push rod 364 is rotatably connected to one end of the second rotating seat 34, and the other end of the second rotating seat 34 is rotatably connected to the other end of the antenna mounting plate 40.

[0059] After the second cylinder 36 is connected to the external air source and electronic control system, when the second cylinder 36 operates, it pushes the second push rod 364 out of the second cylinder body 362. Since the end of the second push rod 364 is rotatably connected to one end of the second rotating seat 34, the entire second rotating seat 34 rotates horizontally relative to the second fixed seat 32 during the extension of the second push rod 364. During the above rotation, since both ends of the antenna mounting plate 40 are rotatably connected to the antenna tilt adjustment mechanism 20 and the antenna azimuth adjustment mechanism 30 respectively, the antenna mounting plate 40 and the antenna tilt adjustment mechanism 20 rotate synchronously relative to the second fixed seat 32 in the horizontal direction, thereby enabling the adjustment of the left and right azimuth angles of the antenna mounted on the antenna mounting plate 40.

[0060] Preferably, a second mounting groove 322 is provided at one end of the second fixing seat 32; the retaining rod 10 is fixed in the second mounting groove 322, thereby fixing the entire second fixing seat 32 on the retaining rod 10.

[0061] When it is necessary to adjust the position of the entire antenna azimuth adjustment mechanism 30 on the support rod 10, simply loosen the connection between the two. After adjusting the antenna azimuth adjustment mechanism 30 to the appropriate position, tighten the two together again.

[0062] Preferably, it further includes a scale 50 that is arranged parallel to the mast 10 and passes through the first fixing seat 22 and the second fixing seat 32. The height of the antenna azimuth adjustment mechanism 30 relative to the mast 10 can be adjusted by the scale set on the scale 50.

[0063] Preferably, the second fixed seat 32 is rotatably configured such that a second shaft hole 324 is provided at one end of the second rotating seat 34; a second rotating shaft 342 is provided on the second rotating seat 34 at a position corresponding to the second shaft hole 324; the second rotating shaft 342 is rotatably disposed in the second shaft hole 324, thereby realizing the relative rotation of the second rotating seat 34 with respect to the second fixed seat 32.

[0064] More preferably, a second pivot bracket 326 is provided on the second rotating seat 34 at one end where the second mounting groove 322 is opened, and a part of the second cylinder body 362 is rotatably disposed in the second pivot bracket 326, thereby realizing the rotatable placement of the second cylinder body 362 on the second fixed seat 32.

[0065] Preferably, the second rotating seat 34 has a pair of lugs 344 at one end where the second rotating shaft 342 is located, and the second push rod 364 is rotatably disposed in the pair of lugs 344, thereby realizing the rotational connection between the second push rod 364 and one end of the second rotating seat 34.

[0066] In this invention, because an antenna tilt adjustment mechanism and an antenna azimuth adjustment mechanism are simultaneously rotatably connected to the antenna mounting plate, the antenna tilt angle can be adjusted via the antenna tilt adjustment mechanism, and the antenna azimuth angle can be adjusted via the antenna azimuth adjustment mechanism. Therefore, the antenna tilt angle and azimuth angle can be conveniently adjusted.
