Detailed description of the invention

To develop simultaneously embodiment below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, boxboard fabricate block is made up of upper boxboard 10, lower boxboard 11 and flexible sun blanket 12, and flexible sun blanket 12 is clamped by upper boxboard 10 and lower boxboard 11 after drawing in and folding.

As Fig. 2,3, shown in 4 and 5, the manual hold-down mechanism of boxboard of the present utility model mainly comprises and compresses handle 1, handle column 2, handle base 4, handle rotating shaft 5, latch hook rotating shaft 6, latch hook 7, upper boxboard hook 8, lower boxboard hook 9 and corresponding fastening gauge member.Except upper boxboard hook 8, remaining part is all fixed on the side of lower boxboard 10.

Lower boxboard hook 9 and handle base 4 are fixed on the side of lower boxboard; Upper boxboard hook 8 is fixed on boxboard side, and corresponding with the position of described handle base 4.The opening of lower boxboard hook 9 and upper boxboard hook 8 towards all back to handle base 4.Handle column 2 bottom has disc projection, is embedded in cylindrical grooves corresponding in handle base 4, and can rotates around body central axle; Handle column 2 stretches out the part of groove along being processed with through hole with central axis direction; The bottom compressing handle 1 is connected with described through hole by handle rotating shaft 5, and compressing handle 1 can around the central axis of handle rotating shaft 5.The middle part compressing handle 1 is provided with the cylindrical hole parallel with handle rotating shaft 5, and latch hook rotating shaft 6 is through described cylindrical hole, and the two ends vertical centre direction of principal axis exposed is processed with through hole; Latch hook 7 is U-shaped structure, and two free ends are each passed through the through hole at latch hook rotating shaft 6 two ends, and is fixedly connected with latch hook rotating shaft 6, and latch hook 7 can around the central axis of latch hook rotating shaft 6.Wherein fixed form is: latch hook 7 liang of free ends are processed with screw thread, and each free end is clamped to latch hook rotating shaft 6 both sides by two setting nuts 3.

In the Spacecraft Launch stage, manual hold-down mechanism does not work, and just uses, therefore be fixed in the side of lower boxboard 10 when it just needs to change solar wing in-orbit, independent placement.In order to avoid its affect flexible sun blanket 12 in-orbit time Automatic-expanding motion, be provided with lower boxboard hook 9, at ordinary times latch hook 7 is linked up with 9 with lower boxboard and is connected, its position is fixed, as shown in Figure 2 state.

When needing in-orbit to change solar wing, first by actuating device etc., flexible sun blanket 12 is drawn in.After flexible sun blanket 12 draws in and puts in place, the boxboard of flexible sun blanket 12 both sides is brought to certain distance, now, by astronaut's M/C, compression handle 1 is lifted, compresses handle 1 and rotate up around handle rotating shaft 5, and then band moveable lock hook 7 is thrown off from lower boxboard hook 9.

Compress the parts such as handle 1 and latch hook 7, be fixed on handle column 2 by handle rotating shaft 5,360 ° can be done with handle column 2 around its center shaft and rotate freely.Astronaut now, manually will compress handle 1 around handle column 2 half-twist, and band moveable lock hook 7 rotates the position of supreme boxboard hook 8, latch hook head be caught on upper boxboard hook 8.Manual depression compresses handle 1, compress handle 1 to be rotated down around handle rotating shaft 5, and then band moveable lock hook 7 moves backward, upper boxboard 10 and lower boxboard 11 is strained, compress inner flexible sun blanket 12, reach and make boxboard and the as a whole object of flexible sun blanket 12 one-tenth.

In latch hook 7 and latch hook rotating shaft 6 junction, be provided with latch hook setting nut 3, by the collapsing length of its adjustable latch hook 7, to adapt to the thickness deviation demand of sun blanket, the also clamping load of adjustable flexible sun blanket 12.

In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
