Specific implementation mode
Invention is further described in detail below.
Referring to Fig. 1, electric-controlled pneumatic type auromatic unlocking device device of the present invention includes housing assembly, piston component, throws bullet group
Part.Wherein：
The housing assembly：Including cylinder body 4, clip 5, wherein the cylinder body is hollow structure, piston component and throwing bullet group
The internal cavities in cylinder body are arranged in part.The clip 5 is sleeved on cylinder body 4, for being fixed with aircraft body component.In addition, cylinder body 4
The plug for drogue rope is provided in the pilot hole on top.
The piston component：Including bearing 11, piston, pulley 10, pressing plate 6, diaphragm seal 7, closing in cap 8.Wherein, bearing 11
It is fixed on inner chamber of cylinder block, and blocks cylinder interior cavity, but is intermediate with hole for gas to pass through.Piston is movably arranged on cylinder body
Inner cavity, and be dynamic sealing above bearing, and between piston edge and inboard wall of cylinder block, therefore piston and bearing and cylinder body
Inner wall forms closed cavity.One end that piston is closed in bearing 11 is arranged in the pulley, is oriented to for umbrella rope.
The throwing bullet component being connect with electrical control mechanism is also disposed at cylinder interior cavity, is located at below bearing.The throwing bullet group
