Antenna fixing device

Abstract

The invention discloses an antenna fixing device, which comprises: a supporting seat which is in an L shape; and a supporting structure located above the supporting seat and comprising a fixed base, a telescopic rod, an adjusting screw rod and an extrusion block, wherein the fixed base is fixedly arranged above the supporting seat, the adjusting screw rod is installed on one side of the fixed base in a threaded mode, and an extrusion block is rotationally arranged at one end, positioned in the fixed base, of the adjusting screw rod. According to the invention, through the arrangement of the supporting seat, the supporting group can be conveniently installed at a certain position through the fastening bolt, the antenna can be inserted into the fixed base when the antenna is fixed, the bottom of the antenna can be fixed by the extrusion block by rotating the adjusting screw rod, and the clamping block is fixedly installed at one end of the telescopic supporting column and is similar to a common spring clamp, so that the upper portion of the antenna can be fixed, the antenna is prevented from shaking, and the fixing effect is improved.

Description

technical field [0001] The invention relates to the technical field of antenna fixing equipment, in particular to an antenna fixing device. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the ...

[0003] The existing terminal antenna installation is all fixed by the built-in magnetic suction cup. At present, there is no special location for installing the antenna outside the electric energy meter screen and metering box. When the material of the screen cabinet and the meter box is iron, the antenna installation can be done through its own The magnetic suction cup is fixed, but in order to ensure a good signal and avoid signal shielding interference, the antenna needs to be installed outside the screen cabinet and metering box, which is easy to be touched by external force, displacement or even drop; in addition, the magnetism of the antenna magnet will be affected by various These reasons gradually weaken, degaussing occurs, and eventually the antenna falls off, resulting in a decrease in signal and affecting the success rate of acquisition; the hanging antenna may even cause a short circuit in the line, causing line tripping and other safety accidents

When the material of the watch box is non-ferrous, the antenna cannot be fixed with the self-contained magnetic suction cup. Placing it in the watch box will affect the signal reception and affect the maintenance of the equipment in the watch box; binding it outside the watch box does not meet the requirements of the regulations. It is not beautiful, and because of long-term operation, the binding is loose, and the antenna will drop
