Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a multi-band antenna structure for wireless communication. Background Technology

[0002] Wireless communication antennas, especially parabolic antennas used to receive satellite signals, are indispensable key devices in modern communication systems. The main function of these antennas is to efficiently collect and focus weak electromagnetic wave signals from distant signal sources. In order to ensure the quality of signal reception, the parabolic reflector of the antenna must be aligned with the direction of the signal source with extreme precision. Any slight angular deviation may cause the signal strength to drop sharply or even be completely interrupted.

[0003] To maintain this precise alignment, the mechanical stability and secure installation of the antenna structure become the primary technical prerequisites. Traditional antennas are usually fixed with simple bolts and brackets, which can be used in ideal environments. However, antennas are mostly installed outdoors and are subjected to various environmental factors such as wind, rain, and vibration over a long period of time. Under the continuous action of these factors, traditional fastening methods are prone to loosening, causing the antenna to undergo slight displacement or shaking, thereby destroying the preset precise alignment angle and causing signal instability.

[0004] Furthermore, precise adjustment of the antenna angle is equally crucial during the initial installation and commissioning phase. Existing antenna adjustment components often have simple structures and rely heavily on friction between components for positioning. The adjustment process feels stiff and prone to jamming or jumping, making it difficult for operators to perform smooth and precise angle fine-tuning. This imprecise adjustment method often results in the antenna not being able to be adjusted to the optimal angle for signal reception. Even if the antenna itself has excellent performance, it cannot play its due role, fundamentally affecting the communication quality.

[0005] Therefore, existing antenna structures generally have a core design flaw: they are difficult to simultaneously ensure long-term structural stability after installation and high-precision smooth adjustment capability during installation. This structural deficiency directly leads to unreliable signal reception. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a multi-band antenna structure for wireless communication, aiming to improve the problems of insufficient installation and fixation, susceptibility to environmental influences and shaking, low angle adjustment accuracy and difficulty in process control of the existing multi-band antenna structure for wireless communication. This utility model aims to provide a multi-band antenna structure for wireless communication with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-band antenna structure for wireless communication, comprising: a chassis, a support column, a parabolic reflector and a frequency downconverter; as well as an adjustment assembly and a rotation fastening assembly.

[0008] The lower end of the support column is slidably connected to the chassis, and the frequency reducer is located at the signal focal point of the parabolic reflector.

[0009] Furthermore, the adjustment component is rotatably connected between the upper end of the support column and the parabolic reflector to adjust the angle of the parabolic reflector; the rotation fastening component is mounted on the chassis to securely install the entire antenna structure in a predetermined position.

[0010] Preferably, the adjustment assembly includes a hinge damper configured to provide a smooth damping force during the adjustment of the parabolic reflector angle.

[0011] Preferably, the adjustment assembly further includes a shim disposed on the inner wall of the hinge damper for high-precision fine-tuning of the angle of the parabolic reflector.

[0012] Furthermore, the adjustment assembly also includes a connector fixedly connected to the parabolic reflector and a connecting block fixedly connected to the support column, with the hinge damper and the gasket disposed between the connector and the connecting block.

[0013] Preferably, the rotary fastening assembly includes a fixed base, a hollow bolt, and an opening and closing fastener. The hollow bolt is threaded into the locking housing, and the opening and closing fastener is sleeved on the outside of the hollow bolt and deforms when the hollow bolt is tightened to fasten the support column.

[0014] Furthermore, the rotary fastening assembly also includes a locking housing through which the hollow bolt passes, and the opening and closing fastener is housed within the locking housing.

[0015] Preferably, the opening and closing fastener deforms during the tightening of the hollow bolt due to axial compression from the hollow bolt and the fixed base.

[0016] Preferably, the frequency downconverter is fixedly connected to the parabolic reflector via at least one feed rod.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a rotating fastening component, especially an opening and closing fastener that can deform during the tightening process, the problem of antenna installation relying solely on bolt fastening force in the prior art, resulting in insufficient connection and easy swaying or displacement due to external vibration or wind force, is solved. This achieves the technical effect of greatly improving the stability and reliability of antenna structure installation, ensuring that the antenna can maintain a precise alignment angle even in harsh environments.

[0018] 2. This utility model, by setting an adjustment component, which has a built-in hinge damper and a replaceable shim, solves the problems of uneven antenna angle adjustment operation, easy overshoot due to excessive force, and difficulty in high-precision fine adjustment in the prior art. It achieves the technical effect of making the angle adjustment process stable and controllable, while realizing high-precision fine adjustment, and significantly improving the accuracy and efficiency of satellite alignment.

[0021] 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.

[0022] Please refer to Figures 1 to 4This utility model provides a multi-band antenna structure for wireless communication, aiming to solve the problems of unstable fixing and inaccurate adjustment of existing wireless communication antenna structures.

[0023] like Figure 1 and Figure 2 As shown, a multi-band antenna structure for wireless communication includes a chassis 1, a support column 2, a parabolic reflector 3, a frequency downconverter 4, an adjustment assembly 5, and a rotation fastening assembly 6. The lower end of the support column 2 is fixedly connected to the chassis 1. The parabolic reflector 3 is rotatably connected to the upper end of the support column 2 through the adjustment assembly 5. The frequency downconverter 4 is located at the signal focal point of the parabolic reflector 3 and is fixedly connected to the parabolic reflector 3 through at least one feed rod. The rotation fastening assembly 6 is located on the inner wall of the chassis 1 and is used to firmly fix the support column 2 in the installation position. As a core part of this plan, please refer to Figure 3 The adjustment component 5 is used to smoothly and precisely adjust the angle of the parabolic reflector 3. The adjustment component 5 specifically includes a connector 501, a hinge damper 502, a shim 503, and a connecting block 504. The connector 501 is fixedly connected to the parabolic reflector 3, and the connecting block 504 is fixedly connected to the support column 2. The hinge damper 502 and the shim 503 are disposed between the connector 501 and the connecting block 504. The hinge damper 502 is configured to provide a continuous and stable damping force during the adjustment of the angle of the parabolic reflector 3, so that the adjustment operation is smooth and avoids excessive angle adjustment due to excessive force. The shim 503 is detachably disposed at the component connection interface of the adjustment component 5. By increasing or decreasing the number of shims 503 or replacing shims 503 of different thicknesses, high-precision fine adjustment of the angle of the parabolic reflector 3 can be achieved. As another core part of this plan, please refer to Figure 4 The rotating fastening assembly 6 is used to provide a stable and reliable installation and fixing effect. The rotating fastening assembly 6 specifically includes a hollow bolt 601, a locking housing 602, an opening and closing fastener 603, and a fixing base 604. The hollow bolt 601 is threadedly engaged with the locking housing 602, and the locking housing 602 is sleeved on the outside of the hollow bolt 601. The opening and closing fastener 603 is also sleeved on the outside of the hollow bolt 601 and is housed in the internal space of the locking housing 602. When fastening is performed by rotating the hollow bolt 601, the opening and closing fastener 603 will deform due to the axial compression from the hollow bolt 601 and the fixing base 604. This deformation causes the opening and closing fastener 603 to contract inward and tightly lock the support column 2, thereby generating a very strong locking force to ensure that the entire antenna structure is firmly fixed in the installation position. Please refer to Figure 3The connecting block 504 of the adjusting component 5 is fixedly connected to the top of the support column 2 by bolts or welding, serving as a fixed base for the adjusting action. The connector 501 of the adjusting component 5 is correspondingly fixedly connected to the back of the parabolic reflector 3, serving as a moving part for the adjusting action. The hinge damper 502 is disposed between the connector 501 and the connecting block 504, forming the rotational pivot of the connector 501 relative to the connecting block 504. During the rotation and adjustment of the parabolic reflector 3, the internal damping structure of the hinge damper 502 can generate smooth... The resistance ensures the continuity and stability of the adjustment action, avoiding sudden changes or jitter in the angle. The shim 503 is detachably set between the mating contact surfaces of the connector 501 and the connecting block 504. By changing the thickness or number of shims 503, the initial pitch angle of the parabolic reflector 3 can be statically and precisely compensated and finely adjusted without rotating the hinge damper 502. This structure, which combines dynamic damping adjustment with static shim fine adjustment, ensures the smoothness of the star angle adjustment process and the accuracy of the final result. As a preferred embodiment, to achieve a more reliable locking and fixing of the antenna base, the structure of the rotating fastening assembly 6 is further defined, please refer to... Figure 4 The rotary fastening assembly 6 also includes a locking housing 602, through which a hollow bolt 601 passes. The opening and closing fastener 603 is completely housed inside the locking housing 602. The hollow bolt 601, the locking housing 602, and the opening and closing fastener 603 together constitute an integrated fastening assembly. When the hollow bolt 601 is screwed into the fixed base 604, the bottom end of the locking housing 602 and the top end of the fixed base 604 will generate bidirectional axial compressive force on the internal opening and closing fastener 603, thereby triggering the opening and closing fastener 603 to produce radial deformation. The presence of the locking housing 602 provides effective constraint and guidance for the deformation of the opening and closing fastener 603, making the generated locking force more concentrated and powerful.

[0024] Working principle: During installation, the chassis 1 is placed in the predetermined installation position. Then, the rotating fastening assembly 6 is operated. The hollow bolt 601 is passed through the chassis 1 and the locking housing 602, aligned with the fixing base 604 below, and tightened. During the tightening process, the locking housing 602 and the fixing base 604 gradually move closer together, applying axial pressure to the opening and closing fastener 603 located inside the locking housing 602. When the pressure reaches a certain level, the opening and closing fastener 603 will undergo radial expansion deformation, pressing tightly inward against the support column 2, generating a huge frictional locking force, thereby firmly fixing the entire antenna structure. When adjusting the angle of the antenna to align with the satellite, the operator can slowly push the parabolic reflector 3. The hinge damper 502 in the adjustment assembly 5 will provide a smooth damping effect, making the rotation process smooth and non-abrupt, which is convenient for coarse adjustment. When high-precision fine adjustment is required, shims 503 of different thicknesses can be added, reduced or replaced between the connector 501 and the connecting block 504. The static pitch angle of the parabolic reflector 3 can be precisely changed by the slight change in the thickness of the shims 503 until the antenna is precisely aligned with the target satellite. Finally, the satellite signal gathered by the parabolic reflector 3 is received by the down-frequency unit 4 and processed.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
