Terahertz-based rapid security check instrument

Abstract

The invention discloses a terahertz-based rapid security check instrument, which comprises workbenches and a conveying frame, wherein a plurality of rolling shafts are arranged between the workbenches; the two ends of the rolling shaft are rotationally connected with the side walls of the two sides of the workbenches correspondingly; a first stop lever rotates clockwise around a first rotating shaft by pushing a spring; meanwhile, a second stop lever is pushed through a middle rod so as to enable the second stop lever to rotate anticlockwise around a second rotating shaft; the first stop leverand the second stop lever move into a middle box; the box body passes through the middle box under the driving of the conveying belt so as to complete the security check work. The arrangement of thespring plays a role in buffering, the box body is driven by the conveying belt to collide with a pulley on the first stop lever, a hydraulic cylinder is prevented from being damaged, the box body is stopped by the first stop lever and then slips relative to the conveying belt, the box body stops moving for security check, and when the first stop lever is damaged, the second stop lever can play a standby role, so that the device continues to operate.

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
