Protective device with good stability for security engineering

Abstract

The invention discloses a protection device with good stability for security engineering, and belongs to the technical field of security engineering. The protection device comprises a mounting frame, the upper surface of the mounting frame is fixedly connected with a shell, and the left and right side surfaces of the inner wall of the shell are fixedly connected with the left and right side surfaces of two vertical plates through sliding rods respectively; and the outer surface of each sliding rod is sleeved with a first spring and a first sliding block, and the front face of each first sliding block is movably connected with the bottom end of a first connecting rod through a pin shaft. According to the protection device with the good stability for the security engineering, by arranging the sliding rods, the first springs, the first sliding blocks, the first connecting rods, a transverse plate and a camera, when the camera is vibrated, the camera moves downwards, so that the camera drives the transverse plate to move downwards, a telescopic rod is shrunk, the transverse plate drives the first sliding blocks to move leftwards through the first connecting rods, the first springs are shrunk, the vibration amplitude of the camera is reduced, and the camera is not prone to being damaged due to vibration.

Description

technical field [0001] The invention belongs to the technical field of security engineering, in particular to a protective device with good stability for security engineering. Background technique [0002] Security refers to security protection, security has three forms of protection, physical defense, human defense, and technical defense. Security engineering is a new profession that is increasingly valued by people. An indispensable part of modern security engineering is the camera. Most of the existing cameras are not With a protective device, the camera is easily damaged by falling objects, and when the camera is subject to a large vibration, the electronic components in the camera are easy to fall off, and the existing camera is easily damaged by criminals when it is set outdoors. When the power supply is cut off, the camera will no longer continue to work, which seriously affects the work of the camera, and lawbreakers can easily avoid the camera to perform illegal act...
