It is against on body body 7, wind spring 4 is mounted on the cylindrical section 10 of rotation lid 1, is blocked by wind spring motion-stopping surface 17, and wind spring 4 has interior
Stop section 20 and outer stop section 21, interior stop section 20 are mounted in the lid card slot 16 of rotation lid 1, and outer stop section 21 is mounted on
In the shell card slot 22 of wind spring shell 3, wind spring shell 3 is mounted on by shell bores 24 in shaft 2, is had on wind spring shell 3
Boss motion-stopping surface 23 contacts after installation with the stop rib 19 of body 7, and there are two shafts 2, each one of left and right, and latch 6 is installed
On the pin hole 11 of rotation lid 1, by 6 stop of latch, the other end is ensured to turn 2 one end of shaft by 12 stop of bushing bottom surface
Axis 2 is not fallen out after installing.
Further, active channel (13) is round, rectangular, diamond shape；
Further, stop ledge (18) is cylindrical, rectangular；It is real by screw, straight pin form with rotation lid (1)
Now connect.
Further, wind spring motion-stopping surface (17) is connect by threaded hole with wind spring (4).
Further, latch (6) is round, rectangular, triangle, is straight pin, screw, bolt, split pin, tack axis
Form.
Further, the boundary of the stealthy boundary of diamond shape (26) and stealthy face (15), active channel face (14) is diamond shape, circle
Shape, rectangular, rectangle, polygon.
Further, the interior dynamic section (20) of wind spring (4) and outer stop section (21), are the forms of coil spring ends bending.
It has the advantage that compared with prior art or good effect
Existing lid is larger, and dismounting is difficult, and the time is long, needs specific purpose tool, be not suitable for can launching in the air mission payload,
The closing of interface, opening, lid, access after the dispensings such as fuel tank, guided missile etc. is stealthy or even the guided missile of part type, pair are oily
Oil circuit, machinery excuse after case dispensing, circuit interface lid are not closed, and not closed cavity generates a large amount of scattering source, greatly
The big radar scattering area for increasing aircraft, to the stealthy extremely disadvantageous of aircraft, this rotary stealthy multi-functional lid can be with one for this
Bodyization realizes that self-closed, spatial volume is small, simple in structure, reliable, light-weight, can greatly improve the stealth of aircraft
Energy.
