A fast security inspection device based on terahertz

Abstract

The invention discloses a terahertz-based rapid security inspection instrument, which includes a workbench and a transmission frame. A number of rollers are arranged between the workbenches. Pushing the spring makes the first blocking lever rotate clockwise around the first rotating shaft, and at the same time pushes the second blocking lever through the intermediate rod, so that the second blocking lever rotates counterclockwise around the second rotating shaft, and the first blocking lever and the second blocking lever move to Inside the middle box, the box body is driven by the conveyor belt through the middle box to complete the security inspection work. The setting of the spring acts as a buffer, and the box body will collide with the pulley on the first stop bar driven by the conveyor belt to avoid damage to the Hydraulic cylinder, the box body will slip between the conveyor belt after being blocked by the first stop bar, so that the box body stops moving for security inspection. When the first stop bar is damaged, the second stop bar can play a backup role, making the device keep running.

Description

technical field [0001] The invention relates to the field of security inspection equipment, in particular to a terahertz-based rapid security inspection instrument. Background technique [0002] Security inspection machines are widely used in airports, railway stations, subway stations, bus stations, government buildings, embassies, conference centers, exhibition centers, hotels, shopping malls, large-scale events, post offices, schools, logistics industry, industrial testing, etc. Among them, the terahertz-based security detector has the characteristics of accurate detection and low radiation. [0003] During the use of the existing security detectors, when the size of the cargo box is different, the distance between the two transmission racks cannot be adjusted. It is only suitable for the inspection of boxes of the same size and cannot meet the inspection work of boxes of different sizes. , the scope of application of the device is small, and it is not convenient to carr...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a fast security inspection instrument based on terahertz to solve the problem that the existing security inspection instrument cannot realize the distance adjustment between the two transmission racks when the size of the cargo box is different during use. The inspection of boxes of the same size cannot meet the inspection work of boxes of different sizes. The scope of application of the device is small, and it is not convenient for box safety inspection; the existing security inspection instrument cannot adjust the height of the detector during use. The distance between the detector and the box cannot be shortened, and the distance between the detector and the box is relatively large, which makes the detection inaccurate; during the use of the existing security detector, the box cannot stop under the detector, The inspection is not thorough, and the box body will collide with the pulley on the first stop bar under the drive of the conveyor belt, which is easy to damage the hydraulic cylinder. When the first stop bar is damaged, the device cannot continue to operate, and there is no problem with backup equipment
