Abstract

The utility model relates to an ejection parachute, which is composed of a four-leaved parachute shell, parachute cloth, an upper net cover, a lower net cover, a metal ball and an ejection rod, wherein the parachute cloth is tied on the inner side of the parachute shell through a thin line, and the parachute shell is hinged with the upper net cover together. The upper and the lower net covers are oppositely buckled together, and the metal ball is arranged between the upper and the lower net covers. When the ejection parachute is used, the ejection rod is inserted in a parachute body of the folded parachute, and a person holds a handle of the ejection rod by a hand and tries to upwardly eject the parachute. The parachute rises because of bearing the force, and the rising process of the parachute is changed to the falling process after the parachute arrives at certain height. Then the parachute cloth causes the parachute shell to become open by supporting and automatically braces, and the ejection parachute increases the air resistance and reduces the lowering speed of the parachute. Therefore, the parachute is caused to slowly fly down and is very interesting.
