Title:
SHIELDING STRUCTURE AND SAFETY INSPECTION CHANNEL OF SAFETY INSPECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/010953
Kind Code:
A1
Abstract:
A shielding structure of a safety inspection device. The shielding structure of the safety inspection device comprises a first carbon fiber layer (10), a polyurethane layer (20), and a second carbon fiber layer (30) which are sequentially stacked, so that a shielding channel (1') having two opened ends is configured; the second carbon fiber layer (30) is an outer layer of the shielding channel (1'); the first carbon fiber layer (10) and the second carbon fiber layer (30) are made of a carbon fiber material; the polyurethane layer (20) is made of a polyurethane material. Also provided is a safety inspection channel (1000) of the safety inspection device using the shielding structure (1'). The carbon fiber layers (10, 30) have good strength, and both sides of the polyurethane layer (20) are covered with the carbon fiber layers (10, 30) to ensure the overall strength, thereby improving the rigidity of the shielding structure (1'); the influence of the rigidity of the shielding structure on imaging quality is small, the rigidity of the shielding structure (1') is improved under the premise of reducing the influence on the image quality. In addition, the total weight is reduced, and the overall cost is reduced.
