Abstract

The invention relates to the field of security inspection equipment, in particular to a device for performing security detection using X-rays, comprising a fuselage and detection chambers provided in the fuselage and connected to the left and right sides of the fuselage, and the detection chamber can be rotated. A rotating frame is provided, and a power receiving ring is provided at a middle position of the rotating frame. A sliding groove is provided in four brackets provided on the rotating frame, and an electric pole is slidably provided in the sliding groove. A first spring is provided between the power receiving pole and the wall of the sliding groove, and the power connecting wire is electrically connected between the power receiving pole and the power receiving ring. The invention provides a device for detecting security by using X-rays.

Claims

1. A device using X-rays for security detection includes a fuselage and a detection cavity provided in the fuselage and connected to the left and right sides of the fuselage. A power receiving ring is provided at the middle position of the rotating frame, a sliding groove is provided in the four brackets provided on the rotating frame, and a power receiving pole is slidably arranged in the sliding groove. A first spring is provided between the sliding groove wall bodies, and an electrical wire is electrically connected between the electric pole and the electric ring, and an X-ray generator (not shown) is disposed in the front end wall of the lower left corner.), An X-ray imager that generates X-rays due to receiving an X-ray generator (not shown) is provided in the rear end wall of the lower left corner of the detection cavity, and the left end wall and the bottom wall of the detection cavity are provided with A contact that cooperates with the power pole, and a controller that controls the activation of the X-ray generator (not shown) is provided between the two contacts, and when the two contacts are connected to the power at the same time When the lever abuts, the controller controls the X-ray generator (not shown) to illuminate the lower left corner of the detection cavity. Once shot, at this time, the X-ray imager receives an X-ray to form an image for security personnel to inspect.
