The shielding structure of the safety inspection equipment includes a first carbon fiber layer, a polyurethane layer and a second carbon fiber layer, which are sequentially stacked to be configured as a shielding channel with two opened ends. The second carbon fiber layer is an outer layer of the shielding channel. The first carbon fiber layer and the second carbon fiber layer are made of carbon fiber materials. The polyurethane layer is made of polyurethane materials. In the present disclosure, the polyurethane board layer is added between the two carbon fiber layers, since the carbon fiber layer has good strength, the carbon fiber layers are covered on the both sides of the polyurethane board to ensure the overall strength, so that the rigidity of the shielding structure can be improved. And the rigidity of the shielding structure has little influence on the imaging quality, so that the rigidity of the shielding structure can be improved while reducing the influence on the imaging quality. In addition, the polyurethane board layer has small density, so that the polyurethane board layer is lighter than the carbon fiber layer, and thus the total weight can be reduced. And, cost of the polyurethane board layer is low, thus reducing the overall cost. [Fig.3] 15
