Description

TECHNICAL FIELD

[0001] The utility model relates to an omnidirectional antenna technical field, specifically adjustable position angle's high gain omnidirectional antenna. BACKGROUND

[0002] In the field of communication technology, high gain omnidirectional antenna is widely used in mobile communication base station, wireless LAN and all kinds of scenes needing all-round signal coverage due to its characteristics of uniformly radiating signals in all directions. In recent years, with the popularization of 5G technology and the explosive growth of Internet of Things devices, more stringent requirements are put forward for the coverage range and strength of communication signals. As a key device to ensure effective transmission of signals, the performance and adaptability of high gain omnidirectional antenna are increasingly concerned.

[0003] Traditional high gain omnidirectional antenna is usually fixedly installed on a support or tower at a specific height. In actual application scenarios, different geographical environments and building layouts have different requirements for the height of the antenna. For example, in areas with high-rise buildings, due to the shielding of buildings, fixed-height antennas are difficult to achieve comprehensive coverage of the surrounding area, and signals are prone to appear in blind areas, resulting in a decline in communication quality for some users. The angle of the traditional omnidirectional antenna is usually fixed, which means that in a complex electromagnetic environment, the antenna cannot adjust the radiation angle according to the actual situation to avoid interference sources or enhance the signal strength in a specific direction. For example, when multiple antennas are used in close proximity, due to the unadjustable angle, signal interference may occur, reducing the efficiency of the entire communication system.

DETAILED DESCRIPTION

[0032] The utility model will be further described below in combination with the drawings.

[0033] Embodiment one:

[0034] As Figures 1 to 6 shown, a high-gain omnidirectional antenna with adjustable position angle, it includes four racks 10 and omnidirectional antenna main body 20, omnidirectional antenna main body 20 is connected with universal ball bearing 21, wherein at least one rack 10 is provided with guide assembly, universal ball bearing 21 is installed on guide assembly, guide assembly is used to make universal ball bearing 21 drive omnidirectional antenna main body 20 moves in vertical direction, four racks 10 form the inside of region and are provided with moving ring stand 30, moving ring stand 30 moves along the height direction of rack 10, and moving ring stand 30 is provided with fixed assembly between rack 10, and fixed assembly is used to fix moving ring stand 30, to make moving ring stand 30 stably keep in particular height, the top side of moving ring stand 30 is rotatably connected with rotating plate 31, and rotating plate 31 is provided with adjusting fixing piece, adjusting fixing piece is connected with the bottom end of omnidirectional antenna main body 20, and adjusting fixing piece is used to adjust the angle of omnidirectional antenna main body 20, and rotating plate 31 is provided with connecting assembly between moving ring stand 30, and connecting assembly is used to fix rotating plate 31, to make rotating plate 31 no longer rotate.

[0035] After the frame 10 is fixed, the movable ring frame 30 can be moved according to the actual situation during use. At this time, the rotating plate 31 and the omnidirectional antenna body 20 move accordingly. The omnidirectional antenna body 20 is adjusted to a suitable height according to the specific situation during use. Then, the movable ring frame 30 is fixed by the fixing component. The angle of the omnidirectional antenna body 20 can be adjusted by adjusting the fixing component and the universal ball bearing 21. By rotating the rotating plate 31, the adjustment angle range of the omnidirectional antenna body 20 can be further expanded. The rotating plate 31 is fixed by the connecting component, thereby adjusting the omnidirectional antenna body 20 to a suitable height and angle, so that the communication quality and communication efficiency of the omnidirectional antenna body 20 are better.

[0036] It should be noted that the rotation center of the rotating plate 31 is the same as the center of the moving ring frame 30.

[0037] like Figure 3 and Figure 4 The fixing assembly includes multiple fixing holes 101 opened on the frame 10 and a telescopic rod 32 installed at the middle of the bottom side of the movable ring frame 30. The output end of the telescopic rod 32 is connected to a movable seat 33. Four connecting rods 34 are hinged on the movable seat 33. A fixing block 35 is hinged to the end of each connecting rod 34 away from the movable seat 33. A fixing rod 36 that matches the size of the fixing hole 101 is fixedly connected to one side of each fixing block 35. The fixing rod 36 is inserted into the interior of the fixing hole 101. Four guide reset structures are evenly arranged on the movable ring frame 30. The guide reset structures are connected to the fixing blocks 35 and are used to guide the fixing blocks 35 and make the fixing blocks 35 automatically reset.

[0038] The guide reset structure includes a guide groove 301 formed on the bottom side of the movable ring frame 30. A guide rod 37 and a reset spring 38 are fixedly connected to the inner wall of the guide groove 301. The end of the reset spring 38 is connected to a fixed block 35. The fixed block 35 is slidably connected to the guide groove 301. The guide rod 37 passes through the fixed block 35. The fixed block 35 is slidably connected to the guide rod 37.

[0039] Before adjusting the height of the movable ring frame 30, first move the output end of the telescopic rod 32 downwards. At this time, the movable seat 33 moves accordingly. Under the connecting action of the connecting rod 34, the fixing block 35 moves towards the middle position of the movable ring frame 30. As the fixing block 35 moves, it will compress the return spring 38, and then move the movable ring frame 30. At this time, the omnidirectional antenna body 20 moves accordingly. Adjust the omnidirectional antenna body 20 to a suitable height according to the actual situation during use, and make the fixing rod 36 correspond to the position of the fixing hole 101 at a suitable height. Then slowly release the output end of the telescopic rod 32. Under the reaction force of the return spring 38, the fixing rod 36 is inserted into the interior of the fixing hole 101, thereby fixing the movable ring frame 30 and fixing the omnidirectional antenna body 20 at a suitable height.

[0040] like Figures 1-3 The adjusting fixing component includes a slider 40 that is slidably mounted on the rotating plate 31. A support rod 41 is hinged to the top side of the slider 40. The top end of the support rod 41 is hinged to the bottom end of the omnidirectional antenna body 20. A fixing bolt 42 is threadedly connected to one side of the slider 40. Multiple fixing holes 311 are evenly provided on one side of the rotating plate 31. The fixing bolt 42 passes through the inside of the fixing hole 311. A fixing nut is threadedly connected to the outer surface of the fixing bolt 42.

[0041] When fixing the angle of the omnidirectional antenna body 20, the slider 40 is moved along the length of the rotating plate 31. At this time, the omnidirectional antenna body 20 can be rotated by the support rod 41 and the universal ball bearing 21, thereby fixing the omnidirectional antenna body 20 to a suitable angle. The fixing bolt 42 passes through the fixing hole 311 in a suitable position, and then the fixing nut is threaded to the fixing bolt 42 and the fixing nut is attached to the rotating plate 31 to fix the slider 40, thereby oriented the end of the omnidirectional antenna body 20 in a suitable direction.

[0042] The connecting components include multiple connecting holes 302 opened on the top side of the movable ring frame 30 and connecting bolts 39 threaded to the rotating plate 31. The connecting bolts 39 are inserted into the interior of the connecting holes 302, and the multiple connecting holes 302 are distributed in a circular array about the center of the movable ring frame 30.

[0043] When adjusting the omnidirectional antenna body 20, the rotating plate 31 can be rotated. At this time, the omnidirectional antenna body 20 can be rotated by adjusting the fixing component and the universal ball bearing 21. Through the cooperation with the adjusting fixing component, the angle adjustment range of the omnidirectional antenna body 20 is made wider. After the rotating plate 31 is rotated to the appropriate position, the connecting bolt 39 is inserted into the interior of the connecting socket 302 in the appropriate position, thereby fixing the rotating plate 31 and fixing the rotating plate 31 in the appropriate position.

[0044] The guide assembly includes a guide rod 13 with a T-shaped cross-section. The guide rod 13 passes through the frame 10 and is slidably connected to the frame 10. A connecting plate 14 is connected to the top of the guide rod 13, and a lifting ring 15 is connected to the end of the connecting plate 14. A universal ball bearing 21 is installed on the top side of the lifting ring 15.

[0045] During the movement of the omnidirectional antenna body 20, the universal ball bearing 21 drives the lifting ring 15 to move. At this time, the connecting plate 14 drives the guide rod 13 to move. The guide rod 13, the connecting plate 14 and the lifting ring 15 can support the universal ball bearing 21 and the omnidirectional antenna body 20, so as to avoid the omnidirectional antenna body 20 from shifting its position during the movement and ensure that the omnidirectional antenna body 20 moves smoothly.

[0046] The omnidirectional antenna body 20 includes an antenna mast 22, and multiple radiating arms 23 are connected to the ends of the antenna mast 22. The multiple radiating arms 23 are symmetrically distributed about the central axis of the antenna mast 22.

[0047] The radiating arms 23 are symmetrically distributed on the horizontal plane. The electromagnetic waves radiated by each radiating arm 23 produce interference and superposition effects in a specific direction in space. In the main radiation direction, the electromagnetic waves generated by each radiating arm 23 are superimposed in phase, which greatly enhances the signal strength and effectively improves the antenna gain. Furthermore, the multiple radiating arms 23 ensure that the signal is radiated uniformly in all directions, so that the omnidirectional antenna body 20 has omnidirectional radiation characteristics on the horizontal plane.

[0048] It should be noted that the antenna mast 22 passes through the inside of the lifting ring 15, and the diameter of the antenna mast 22 is smaller than the inner diameter of the lifting ring 15, so as to ensure that the antenna mast 22 can smoothly drive the radiating arm 23 to rotate.

[0049] A connecting ring 11 is connected to the top of each of the four racks 10, which connects the four racks 10 to ensure the stability of the racks 10.

[0050] It should be noted that the antenna mast 22 passes through the inside of the connecting ring 11, and the diameter of the antenna mast 22 is smaller than the inner diameter of the connecting ring 11, so that the antenna mast 22 can move smoothly and drive the radiating arm 23 to rotate.

[0051] Example 2:

[0052] like Figure 7 As shown, in order to further optimize the technical solution of this application, the rotating plate 31 can be replaced with a linear module, and the slider 40 is moved by the linear module. The telescopic rod 32 can be replaced with an electric push rod, and a motor mounting bracket is installed on the top side of the moving ring frame 30. A motor 50 is installed on the motor mounting bracket, and the output end of the motor 50 is connected to the linear module.

[0053] During actual use, the motor, linear module, and electric push rod can all be controlled by external control equipment. By starting the motor 50, the linear module can be rotated, which in turn drives the omnidirectional antenna body 20 to rotate via the slider 40 and the support rod 41. By controlling the linear module, the slider 40 can be moved along the direction of the linear module, which in turn drives the omnidirectional antenna body 20 to rotate via the support rod 41 and the universal ball bearing 21. By controlling the electric push rod, the movable seat 33 can be moved and fixed in a suitable position. This eliminates the need for the operator to constantly pull the movable seat 33, thereby reducing the operator's workload and making the control of the omnidirectional antenna body 20 angle highly automated. It also allows for remote adjustment of the omnidirectional antenna body 20 angle.

[0054] It should be noted that the working principles of the remote control motor 50, battery push rod, and linear module are existing mature technologies, and therefore are not described in detail.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0056] 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.
