Safe adjustable concealed antenna

Abstract

The invention discloses a safe adjustable concealed antenna comprising a signal transceiver column, a mounting box and a telescopic rod. The mounting box consists of a box body, a box cover, a ring gear, a driven shaft, a first bearing seat and a driving gear, a driving shaft, a motor, a guide column, a moving block and a bar-shaped hole. Sliding blocks are fixed at the two ends of the moving block. Chutes are formed in the side walls of the box body; limiting slots are formed in the bottoms of the chutes; and limiting blocks are arranged in the limiting slots in a sliding manner. A hinge baseis arranged at the center of the top of the mounting block; and a sliding hole is formed in the box cover. According to the invention, the telescopic rod is used for carrying out height adjustment onthe mounting box arranged at the top of the telescopic rod to change the height of the signal transceiver column; and the position of the signal transceiver column can be changed to receive the signal conveniently. When sliding to one end of the sliding hole, the signal transceiver column is placed in the sliding hole by the hinge base; and when the antenna is not in use, the safety of the signaltransceiver column is protected effectively.

Description

technical field [0001] The invention relates to the radio field, in particular to a safe and adjustable hidden antenna. Background technique [0002] A safety adjustable hidden 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 safe and adjustable hidden antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires safely adjustable hidden antennas. General safety adjustable hidden antennas are reversible, that is, the same pair of safety adjustable hidden antennas ...

AI Technical Summary

Problems solved by technology

[0003] Most of the safety adjustable hidden antennas installed on some existing small devices are designed to be easily and freely removed. The purpose of this is to avoid damage to the safety adjustable hidden antennas when these devices are transported, and now Some safety adjustable hidden antennas are often designed to be retractable, but although the current safety adjustable hidden antennas can be easily disassembled from the equipment, such safety adjustable hidden antennas are very fragile and not securely fixed, and The surface layer of this retractable safety adjustable hidden antenna is often covered with metal, and the human body can easily touch the safety adjustable hidden antenna and cause damage to it
