Electronic information anti-jamming device

Abstract

The invention discloses an electronic information anti-jamming device, and the device comprises an anti-jamming device body; a cover body is arranged on the top of the outer wall of the anti-jamming device body, a column body is arranged on the top of the outer wall of the cover body and extends to the bottom of the outer wall of the cover body, a second bearing is arranged on the outer wall of the column body, and the column body is rotationally connected with the cover body through the second bearing; a handle is arranged at the top of the outer wall of the column body, and one ends of the outer walls of the two through hole blocks are fixedly connected to the left side and the right side of the inner wall of an anti-jamming device respectively. According to the electronic information anti-jamming device, when the inner wall of the anti-jamming device needs to be maintained and detected, a user can enable a handle and a rod body to drive a V-shaped plate to abut against an external connecting line, the butt joint stability of the external connecting line and a socket is improved, the external connecting line is prevented from loosening, and the outer wall of a sealing ring is in interference fit with the inner wall of the anti-jamming device; therefore, the cover body and the anti-jamming device can be sealed, and electrical elements in the anti-jamming device are protected from being in contact with dust.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an electronic information anti-jamming device. Background technique [0002] The anti-interference device is the best auxiliary tool to solve the problem of video interference in video surveillance. There are two main methods of anti-jamming devices, one is the frequency-shifting anti-jamming method, which can completely solve the interference; the other is the amplification anti-jamming method, in principle, this anti-jamming device cannot eliminate Interference, but it can effectively reduce the amplitude of interfering signals. [0003] Although the existing anti-jamming device can realize the anti-jamming of information, when the existing anti-jamming device is used for internal maintenance and inspection, it is necessary to disassemble multiple bolts outside the anti-jamming device, and then repair the interior of the anti-jamming device Detection is a more in...
