Description

Technical Field

[0001] The present invention relates to the field of antenna technology, and in particular to a double-throw convergence antenna. Background Art

[0002] An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or performs the opposite conversion. It is a component used to transmit or receive electromagnetic waves in radio equipment. Engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, all of which use electromagnetic waves to transmit information, rely on antennas to work.

[0003] However, the existing dual-throw convergence antenna has poor flexibility. After installation, the staff cannot adjust the antenna focusing angle at will according to needs, so the staff can only determine the antenna focusing angle in advance before installation. In addition, during the use of the antenna, the antenna receives poor signals and the antenna also loses signals due to external reasons. For this reason, we propose a dual-throw convergence antenna. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a dual-throw convergence antenna to solve the problems mentioned in the above background technology, such as the dual-throw convergence antenna has poor flexibility, cannot adjust the antenna focusing angle as required, and has poor received signals.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a dual-throw convergence antenna, comprising a support rod, the bottom of the support rod is fixedly connected to a base, the top of the base is threadedly connected to a fixing screw, one side of the support rod is threadedly connected to an adjusting screw, the inside of the support rod is movably connected to a spring, the top of the support rod is movably connected to a telescopic rod, the top of the telescopic rod is fixedly connected to an antenna body, the outside of the telescopic rod is fixedly connected to a fixing sleeve, both sides of the fixing sleeve are fixedly connected to a mounting frame, one side of the mounting frame is movably connected to a bolt, the mounting frame is fixedly connected to a bracket by bolts, and one side of the bracket is fixedly connected to a metal shielding plate.

[0008] Further preferably, a flat antenna is fixedly connected to one side of the metal shielding plate, a guide plate is fixedly connected to the interior of the flat antenna, and a metal vibrator is fixedly connected to one side of the guide plate.

[0009] Further preferably, a plurality of the metal vibrators are provided, and the plurality of the metal vibrators are arranged at equal intervals.

[0010] Further preferably, the support rod is made of carbon steel material, and the support rod is vertically erected at the center of the top of the base.

[0011] Further preferably, a signal line is fixedly connected inside the antenna body, and one end of the signal line is electrically connected to a transmission line.

[0012] Further preferably, the cross-sectional shape of the guide plate is an "arc-shaped" structure, and the outer surface of the guide plate is smooth.

[0013] (III) Beneficial effects

[0014] The present invention provides a dual-throw convergence antenna, which has the following beneficial effects:

[0015] (1) This dual-throw convergence antenna is provided with a telescopic rod, a mounting frame and a bracket. When installing the antenna, the staff installs the bracket on the flat antenna to the inner side of the mounting frame and fixes it with bolts. When the height of the antenna needs to be adjusted after installation, the staff loosens the adjustment screw and then presses the telescopic rod downward. The telescopic rod will compress the spring, causing the telescopic rod to shrink into the support rod, and then tightens the adjustment screw to lower the height of the antenna. When it needs to be raised, the staff loosens the adjustment screw. Due to the elasticity of the spring, the telescopic rod will be pushed, thereby raising the height of the antenna. The staff can also rotate the fixing sleeve 360 ​​degrees to adjust the direction of the flat antenna, and can also adjust the focusing angle of the flat antenna receiving signal 260 degrees up and down by loosening the bolts. This improves the flexibility of the dual-throw convergence antenna, allowing the staff to adjust the antenna focusing angle at will according to needs.

[0016] (2) This type of double-throw convergence antenna, through the metal shielding plate, guide plate and metal vibrator, when the flat antenna is receiving signals, the cross-sectional shape of the guide plate is an "arc-shaped" structure, so that the guide plate can gather signals from multiple directions, and then the signal receiving capability is expanded by multiple metal vibrators. The metal shielding plate is used to shield the interference of the signal on the back of the flat antenna, thereby avoiding the phenomenon of missing signals or unstable received signals of the antenna, thereby improving the strength of the antenna receiving signal.
