技术领域technical field
本发明涉及天线的角度调节技术领域，尤其涉及一种可调节天线下倾角的天线角度调节装置。The invention relates to the technical field of antenna angle adjustment, in particular to an antenna angle adjustment device capable of adjusting the downtilt angle of the antenna.
背景技术Background technique
目前，市场上现有用来调节天线下倾角的天线调角固定装置大概有三种形式：At present, there are roughly three forms of antenna angle adjustment fixtures available on the market to adjust the antenna downtilt angle:
第一种形式的固定装置是靠螺栓预紧力固定。如公告号为CN 2927337Y的专利公开了一种基站天线调整固定夹具及应用该夹具的天线，其调节下倾角的固定方式通用性较好，但是抗载能力较弱，若安装在较长较重的天线上或者使用的环境风速大时，存在天线下倾角发生变化以及夹具变形的风险。The first form of fixing device is fixed by bolt pre-tightening force. For example, the patent with the notification number CN 2927337Y discloses a base station antenna adjustment and fixing fixture and the antenna using the fixture. The fixing method for adjusting the downtilt angle has good versatility, but the load resistance capacity is weak. If it is installed on a longer and heavier When the antenna is used on the antenna or the wind speed in the environment is high, there is a risk that the downtilt angle of the antenna will change and the fixture will deform.
第二种形式的固定装置是直板状结构。如公告号CN 201199541Y的专利公开了一种定向天线夹具，其固定角度装置尺寸过长，容易与抱杆发生干涉以及影响其他装备的安装。A second form of fixture is a bar-like structure. For example, the patent with the notification number CN 201199541Y discloses a directional antenna fixture. The fixed angle device is too long, which easily interferes with the pole and affects the installation of other equipment.
第三种形式的固定装置是扇形或者圆弧形孔状结构。如公告号为CN205921086U的专利公开了一种天线调角装置，其调节角度范围有限，安装极为不易，天线一般都是安装在铁塔上，这使得天线安装人员必须得高空作业，若天线需要调节下倾角，必须从调角片的定位孔中抽出螺栓，插入另一个定位孔中才能实现角度的调节，当安装人员需拧紧螺栓时，需要双手操作，操作难度以及危险系数较高。且若天线较短，此结构调角片上的定位孔则距离较近，存在相交破孔现象。The third type of fixing device is a fan-shaped or arc-shaped hole structure. For example, the patent with the notification number CN205921086U discloses an antenna angle adjustment device, which has a limited range of adjustment angles and is extremely difficult to install. The antennas are generally installed on iron towers, which makes antenna installers have to work at high altitudes. If the antenna needs to be adjusted To adjust the inclination angle, the bolt must be pulled out from the positioning hole of the angle adjuster and inserted into another positioning hole to adjust the angle. When the installer needs to tighten the bolt, both hands are required, and the operation is difficult and dangerous. And if the antenna is short, the distance between the positioning holes on the angle adjustment piece of this structure is relatively close, and there is a phenomenon of intersecting holes.
综上可知，现有技术在实际使用上显然存在不便与缺陷，所以有必要加以改进。In summary, there are obviously inconveniences and defects in the actual use of the prior art, so it is necessary to improve it.

本发明优选天线角度调节装置100的工作原理是：先将第一支臂10、第二支臂20铰接处的螺栓80、第一多角螺栓40和第一紧固件50全部拧松，让连接第一支臂10与调角片30的第一多角螺栓40沿滑槽31移动到所需角度的调角孔32处，再将第一紧固件50拧紧，且保证第一多角螺栓40头底面与调角片30的表面完全接触，通过第一支臂10、第二支臂20的张合来实现天线300的机械下倾角的调节。The working principle of the preferred antenna angle adjustment device 100 of the present invention is: first the bolts 80 at the joints of the first support arm 10 and the second support arm 20, the first polygonal bolt 40 and the first fastener 50 are all unscrewed, so that The first multi-angle bolt 40 connecting the first arm 10 and the angle-adjusting piece 30 moves along the chute 31 to the angle-adjusting hole 32 of the required angle, and then the first fastener 50 is tightened to ensure that the first polygon The bottom surface of the head of the bolt 40 is in full contact with the surface of the angle adjusting piece 30 , and the mechanical downtilt angle adjustment of the antenna 300 is realized by opening and closing the first arm 10 and the second arm 20 .
综上所述，本发明天线角度调节装置包括第一支臂、第二支臂、调角片；通过第一支臂上的第一螺栓沿调角片中滑槽的滑动，再通过第一紧固件固定即可实现两支臂的角度调节，进而实现天线下倾角的角度调节。由于第一支臂上的第一限位孔和第一螺栓的存在，安装人员只需单手操作即可拧紧第一螺栓，从而使得天线角度的调节操作更加方便和安全，且占用空间小，抗载能力强。In summary, the antenna angle adjustment device of the present invention includes a first arm, a second arm, and an angle adjuster; the first bolt on the first arm slides along the chute in the angle adjuster, and then passes through the first The fixing of the fastener can realize the angle adjustment of the two arms, and then realize the angle adjustment of the downtilt angle of the antenna. Due to the existence of the first limiting hole and the first bolt on the first arm, the installer can tighten the first bolt with only one hand operation, which makes the adjustment operation of the antenna angle more convenient and safe, and takes up less space. Strong load resistance.
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
