Put radiographic inspection equipment and be used for scintillation body detector and fixing device wherein

The utility model provides a fixing device for on the casing with the fixed detector of personally experiencing sth. Part of the body to twinkleing of photomultiplier, include: the lens hood of setting on the casing, the lens hood is followed the casing outwards extends, and the one end male opening that supplies photomultiplier has been injectd to the lens hood, flange, the cover is established on the lens hood, and flange's one end is fixed to the casing, and the other end is provided with the external screw thread, and flange's downthehole footpath equals the external diameter of lens hood, be used for photomultiplier's sleeve pipe, sheathed tube one end is provided with the internal thread, with flange's other end screw -thread fit, press the cap, set up at the sheathed tube other end, construct the orientation scintillation body and press down the intraductal photomultiplier of cover. Still relate to scintillation body detector and put radiographic inspection equipment. This technical scheme has solved coupling and offset problem between the photomultiplier and the scintillation body, photomultiplier dismantle easily and the installation method simple, this technical scheme effectively prevents external natural light entering photomultiplier moreover, can improve the reliability of detector.
