Antenna mounting frame

Abstract

The invention provides an antenna mounting frame, comprising an adjustment assembly connected between an antenna and a support. The adjustment assembly is a plane hinge structure formed by at least three shaft levers connected with each other by using articulation shafts as connection shafts and the plane hinge structure has a degree of freedom, wherein one shaft lever is an adjustment screw and the other shaft levers are adjustment arms; at least two articulation shafts connected with the adjustment screw are a first rotation shaft and a second rotation shaft, respectively; the adjustment screw is in threaded screw connection with one of the first and the second rotation shafts, and in threaded screw connection or fixed connection in the direction of the adjustment screw with the other. The invention adopts the rotation action of the threaded screw to change the relative positions of the adjustment arms, and can improve the adjustment precision through decreasing the acting force, adjusting continuously and having self-locking function.

Description

technical field [0001] Embodiments of the present invention relate to antenna installation technologies, and in particular to an antenna installation frame. Background technique [0002] Antennas usually need to be fixed on a support to receive signals. In order to obtain a good reception effect, many antennas are fixed on high places outdoors, such as iron towers, roof towers, etc., and the installation angle of the antenna needs to be adjusted according to the requirements of the received signal. Therefore, the existing antenna mounting frame is generally Both have adjustment components capable of adjusting the angle. [0003] figure 1 It is a schematic structural diagram of an antenna mounting frame in the prior art, and shows a state to be assembled. like figure 1 As shown, the installation frame includes a lower assembly, an upper assembly and an adjustment assembly, which are used to install the antenna 400 on the steel pole 101 . Wherein, the lower assembly inclu...

Problems solved by technology

[0005] During the research process of the present invention, the inventor found that the structure of the above-mentioned antenna mounting frame has the following defects: when the operator adjusts the downtilt angle of the antenna, it is difficult to accurately control the adjustment angle, which leads to the repeated execution of the adjustment operation and is time-consuming, and cannot Guaranteed precise positioning of the downtilt

The reason why it is difficult to accurately control the adjustment angle is that when the operator applies force to the adjustment component to adjust the angle, he also needs to support the gravity of the antenna. The gravity of the antenna is generally large, so it is difficult for the operator to accurately control the magnitude of the applied force, especially in When working at heights, this degree of difficulty is even greater, and it is easy to deviate from the required angle each time the adjustment is made; after adjusting to the required angle, the operator needs to tighten the bolts to lock the rotational degree of freedom originally used for adjustment, thereby fixing the downtilt angle, But in the process of tightening the bolts, it is difficult to keep it fixed because it still needs to bear the gravity of the antenna, and the fixed angle will shift, so the positioning accuracy will decrease
