Full-intelligent safety helmet capable of being rapidly matched with construction drawings

The invention relates to the technical field of intelligent safety helmets, in particular to a full-intelligent safety helmet capable of being matched with construction drawings quickly, which comprises a helmet shell and a visor at the front edge of the helmet shell, a helmet rib is arranged between the helmet shell and the visor, a projection opening is formed in the helmet rib, and a projection device is horizontally and rotatably arranged in the projection opening. The projection opening limits the rotation angle of the projection device, a head support is arranged in the helmet shell and movably arranged in the direction perpendicular to the center of the top of the helmet shell, an automatic reset piece for controlling the head support to reset downwards is arranged between the head support and the helmet shell, and a first synchronous assembly is arranged between the head support and the projection device. When the head support moves upwards, the projection device is driven to rotate upwards, when the
