Abstract

The invention discloses a lifesaving control method based on a lifesaving floating plate. The lifesaving floating plate comprises a shell, a waistband, a micro compressed air bottle, a hard pipe and an air bag, wherein an outer shaft is fixed to a top end of the shell, the micro compressed air bottle is fixed to the outer side of the bottom of the shell, a sealing layer is arranged on the side ofa discharging pipe, the hard pipe penetrates through the shell and is connected with a hose, the hose penetrates through a movable window and is connected with the outer side of the sealing layer, thehose is connected with a bottom end of the air bag, and the air bag is installed on the outer side of the shell. The automatically-unfolded lifesaving floating plate for swimming teaching is advantaged in that structural design is novel, by means of the arrangement, normal swimming activities of a user cannot be affected by assembly of the device, the swimming posture of the user cannot be affected, the lifesaving floating plate can be rapidly triggered to be unfolded when the user needs self rescue in emergency, the area is large, buoyancy is enough, and enough buoyancy and support can be provided for the user with cramp legs.
