The specific embodiment
Embodiment 1: below the present invention is described in further details.As shown in Figure 1,
A mechanical type reserve parachute lockaid gun, comprises time movement, actuating unit and locking controlling organization, wherein:
Actuating unit comprises the piston tube 4, the brake(-holder) block 6 that are contained on casing assembly 5, is contained in power spring 2 and piston 1 in piston tube 5, power spring 2 one end withstand on piston tube 4 right sides, the other end keeps contacting with piston 1 under nature, pulley 14 for locking is housed in the lower end of piston 1, and pulley 14 stretches out the groove on 4 times faces of cylinder of piston tube and can in groove, slide; Brake(-holder) block 6 is hinged on time movement, when pulley goes to the soffit cunning of brake(-holder) block 6, brake(-holder) block 6 is rotated counterclockwise, and pulley 14 is from the soffit of brake(-holder) block 6 slips over, brake(-holder) block 6 turns clockwise under elastomeric element effect, and pulley 14 is stuck on the end face of brake(-holder) block 6;
Time movement comprises gear assembly 13, regulating wheel 11 and the stabilizer 8 that forms driving-chain, and gear assembly 13, under the promotion of actuating unit, promotes stabilizer 8 by regulating wheel 11 and swings timing;
Locking controlling organization comprises the first soft purl 9 of soft purl 7, second and block combination 10, in block combination 10, back-moving spring 12 is housed; The first soft purl 7 inserts after the soft purl 9 of time movement finger lock stabilizer 8, the second inserts block combination 10 and pushes back-moving spring 12 open.
Described power spring 2 is by one or a plurality of spring forms.
Described gear assembly 13 is one or more levels gear.
Described block combination 10 can be contained on flat sheet combination or be contained on casing assembly 5.
