NOVELTY - The utility model claims an infrared thermal imager with good anti-interference effect for detecting building safety, comprising a shell, the top of the left side of the shell is fixedly connected with with a display screen, the bottom of the left side of the shell fixedly connected with button, the inner cavity of the shell is provided with a shielding net, the inner surface of the shell body is provided with a first functional layer, the first functional layer comprises an aluminium-plastic composite belt shielding layer and a polysulfone resin layer, the outer surface of the shell is provided with a second functional layer. The utility model passes through the shell, a display screen, a button, a handle, a switch, a supporting frame, a shielding net, a first functional layer, an aluminium-plastic composite belt shielding layer, a polysulfone resin layer, a second functional layer, a polyurethane waterproof coating layer, graphene anti-electromagnetic wave interference coating layer, EMI anti-interference electromagnetic shielding coating layer, the matching of the fixing block and the movable hole solves the problem that the existing infrared thermal imager has bad anti-interference effect when working, easy to be interfered, so as to affect the detection effect.
