COLLIMATOR AND MOUNTING STRUCTURE AND MOUNTING METHOD THEREOF, AND SECURITY INSPECTION MACHINE

The present disclosure relates to a collimator and a collimator mounting device and method, which belong to the technical field of accessories of the X-ray security inspection machine. The collimator comprises a T-shaped base plate and two lead plates, wherein the two lead plates are arranged side by side and in parallel to each other, and are fixed on a longitudinal plate of the T-shaped base plate and extends to a transverse plate of the T-shaped base plate. The collimator is inserted obliquely into a shielding box, with a gap between the two lead plates in the collimator aligned with a first ray opening. In the collimator and the collimator mounting device of the present disclosure, the base plate of the collimator is formed in the T-shape, which not only can provide sufficient mounting space for the two lead plates, thus shortening a length of the lead plates to reduce deformation, but also can facilitate the insertion of the collimator and thus the assembly, disassembly and adjustment of the collimator. Moreover, the operator can operate directly in a standing posture, which is convenient and labor-saving. Further, it is easier for assembly and adjustment of the security inspection machine comprising the collimator and the collimator mounting device of the present disclosure.
