The invention belongs to the field of bullet train safety protection and provides a novel anti-scalding tray for bullet trains. The novel anti-scalding tray comprises a sundry placement tray body anda circular cup fixing device and has advantages of small size, low cost, simplicity in operation, easiness in folding, scalding prevention and the like. By arrangement of torsion springs and hinges, afunction of folding is realized, the floor space is reduced, and accordingly bullet train space is saved. A circular rotating door and a circular bottom plate are connected through a double-cam connection rod, semicircular rotating doors are driven to move circularly around the torsion springs and the hinges when the circular cup fixing device is pressed by a cup from top to bottom, and rotatingcam devices are driven to move outwards when the circular rotating door rotates, so that a distance between the circular bottom plate and the sundry placement tray body is increased, a cup fixing areais increased, and scalding caused by cup tilting in shaking of the bullet trains is avoided. In addition, the circular bottom plate and the sundry placement tray body are connected through the circular rotating door.
