A dual-frequency omnidirectional high-speed rail antenna that is easy to replace

Abstract

The invention discloses a dual-frequency omnidirectional high-speed railway antenna for easy replacement, relating to the technical field of high-speed railway antennae. The dual-frequency omnidirectional high-speed railway antenna comprises a high-speed railway antenna body, wherein a replacement structure is fixedly arranged on the bottom surface of the high-speed railway antenna body, and a fixing mechanism is fixedly arranged on the bottom surface of the replacement mechanism. According to the dual-frequency omnidirectional high-speed railway antenna for easy replacement, two threaded rodscan drive two sliding plates to slide through two threaded pipes when rotating, so that an insertion rod can be taken out from the inside of the fifth socket through the sliding of the sliding plates, the effect of replacing the high-speed railway antenna body at any time can be achieved, the problem that the high-speed railway antenna body is inconvenient to replace can be effectively avoided, the high-speed railway antenna body can play a fixing role through the falling of the fixing plate, the stability of the high-speed railway antenna body can be effectively improved, the fixing plate can play a buffering role through the elasticity of a second buffer spring, and meanwhile, the fixing plate can be driven to rise upwards when an electromagnetic column does not generate magnetic force.

Description

technical field [0001] The invention relates to the technical field of high-speed rail antennas, in particular to a dual-frequency omnidirectional high-speed rail antenna that is easy to replace. Background technique [0002] China's high-speed passenger railway, often referred to as China's high-speed rail, high-speed rail as a new mode of transportation in modern society, China's high-speed rail speed represents the world's high-speed rail speed, in today's rapid development of mobile communication technology, wireless communication has become a An indispensable means of contact in daily life. On the other hand, high-speed rail has become the preferred mode of transportation for people to travel long distances due to its advantages of comfort, high speed and convenience. The antenna used by high-speed rail has become an essential part of signal transmission. [0003] A few days ago, my country's high-speed rail technology is leading the world, but there are still some prob...
