Antenna angle adjusting device

Abstract

The invention provides an antenna angle adjusting device, including a first support arm, a second support arm and an angle adjusting piece. The bottom of the first support arm is rotatably connected with the bottom of the second support arm, and a first limiting hole is arranged in the first support arm; one end of the angle adjusting piece is provided with a sliding groove, the sliding groove ofthe angle adjusting piece and the first limiting hole of the first support arm are fixed in a screw joint manner through a first bolt and a fastener, and the other end of the angle adjusting piece isfixed on the second support arm; the first fastener locks the first support arm and the angle adjusting piece, an angle between the first support arm and the second support arm is relatively fixed; and when the first fastener loosens the first support arm and the angle adjusting piece, the first bolt can slide along the sliding groove, and drives the first support arm and the second support arm torotate relative to each other, thereby adjusting the angle of the antenna. Thus, the antenna angle adjusting device can enable adjustment operation of the antenna angle to be relatively convenient and safe, and an anti-loading capability is high.

Description

technical field [0001] 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. Background technique [0002] At present, there are roughly three forms of antenna angle adjustment fixtures available on the market to adjust the antenna downtilt angle: [0003] 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. [0004] A second form of fi...

Problems solved by technology

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 For the inclination angle, the bolt must be pulled out from the positioning hole of the angle adjuster and inserted into another positioning hole to realize the angle adjustment. 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 positioning holes on the angle adjustment piece of this structure are relatively close, and there is a phenomenon of intersecting holes

[0006] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
