Abstract

The utility model relates to an automatic parachute opening device based on cam unlocking, and belongs to the technical field of parachutes. The automatic parachute opening device based on cam unlocking comprises a main parachute, a guide parachute, a parachute cabin and an action mechanism. Wherein the parachute bay comprises a bay body, a parachute bay cover and a parachute folding seat and is used for accommodating the main parachute and the guide parachute; the cabin body is hinged to the parachute cabin cover, the cabin body is fixedly connected with the parachute folding base, the main parachute is installed on the parachute folding base, and the guide parachute is contained above the main parachute; the action mechanism is installed at the end, close to the parachute cabin cover, of the cabin body, movably connected with the parachute cabin cover and used for controlling opening or closing of the parachute cabin cover. The action mechanism comprises a rotary lock catch mounted on the cabin body and a fixed lock catch mounted on the parachute cabin cover; and when the action mechanism is unlocked, the rotary lock catch is separated from the fixed lock catch, so that the main umbrella and the guide umbrella are opened. According to the automatic parachute opening device based on cam unlocking, the parachute cabin cover is controlled to be opened or closed through the action mechanism, and a more efficient, safer and more economical solution is provided for air-drop laying of ocean observation and detection equipment.
