The utility model discloses a double-channel double-visual-angle X-ray security inspection device. The security check device comprises a first security check channel, a second security check channel,a first side illumination source and a first top illumination source corresponding to the first security check channel, and a second side illumination source and a second top illumination source corresponding to the second security check channel. Wherein each side illumination source and each top illumination source respectively correspond to one group of detector boxes so as to complete double-view-angle ray scanning. On one hand, the security inspection equipment adopts the independent side illumination source and the independent top illumination source to complete double-view-angle ray scanning, so that the two security inspection channels can operate independently; and on the other hand, each security check channel uses one top illumination source, so that the illumination angle of thetop illumination source is reduced, the complexity and the cost of the X-ray source production and manufacturing process can be reduced, and the reliability of the X-ray source production and manufacturing process is improved. Compared with the prior art, the security inspection equipment is moderate in height and more harmonious and attractive in overall appearance.
