The lower gland comprises a pressing wall, a spring and a wrapping wall, the spring is arranged on the upper end face of the pressing wall, the wrapping wall is arranged at the lower end of the pressing wall, the pressing wall and the spring are arranged on the inner side of the upper gland, the wrapping wall enables the lower end of the upper gland, namely the lower ends of all the vanes to be wrapped, and the shape of the wrapping wall is matched with the lower end of the upper gland. The loading mechanism of the ribbed plate type inflatable unfolding parabolic antenna is used for loading the curly-folded ribbed plate type inflatable unfolding parabolic antenna.
Description
Technical field
The invention belongs to the inflating expanded parabolic antenna technical field of fin-plate type, be specifically related to the loader mechanism of the inflating expanded parabolic antenna of a kind of fin-plate type.
Background technology
The inflating expanded parabolic antenna of fin-plate type has widespread demand at numerous areas, as electronic reconnaissance, navigation, communication, ground prospecting satellite etc.
The structure of inflating expanded antenna, taking flexible material as main, is inflated before FOLD AND PACK expeditiously, has advantages of that delivery volume is little, lightweight and it is high to launch reliability.Large-scale inflating expanded antenna is launched enters the orbit, and after inflating expanded and firmization, can form large space antenna, and inflating expanded antenna is the effective way that does not solve large space antenna structure.
For the inflating expanded parabolic antenna of fin-plate type, not yet there is at present effective loader mechanism, cannot in antenna transmission process, pack compression to the each structure member of antenna, make the each structure member of antenna vibrate, collide under the effect of launching shock power, cause structural failure.
Summary of the invention
To the object of the invention is in order solving for the inflating expanded parabolic antenna of fin-plate type, not yet to have the problem of effective loader mechanism at present, the loader mechanism of the inflating expanded parabolic antenna of a kind of fin-plate type is provided, its technical scheme is as follows:
A loader mechanism for the inflating expanded parabolic antenna of fin-plate type, it comprises upper press cover and lower cover; Described upper press cover is surrounded and is led to fitting by multi-disc blade and connects and composes, upper end and the connector of each blade are rotationally connected by spring hinge, on connector, be provided with connecting screw hole, the setting that curves inwardly of the lower end of each blade, its angle that curves inwardly is less than 90 degree; Described lower cover comprises presses wall, spring and pocket wall, spring is arranged on presses wall upper surface, pocket wall to be arranged on pressure wall lower end, presses wall and spring to be arranged on upper press cover inner side, the lower end that pocket wall is each blade by the lower end of upper press cover catches, and the shape of pocket wall and upper press cover lower end coincide.
Beneficial effect of the present invention is: the inflating expanded parabolic antenna of fin-plate type that can doubling poststack compresses and packs, avoid in antenna transmission process, each structure member vibrates, collides under the effect of launching shock power, cause structural failure, ensure transmitting expansion that paraballon can be safe and reliable.

embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the loader mechanism of the inflating expanded parabolic antenna of a kind of fin-plate type, it comprises upper press cover 1 and lower cover 2; Described upper press cover 1 is surrounded and is led to fitting 1-2 by multi-disc blade 1-1 and connects and composes, the upper end of each blade 1-1 and connector 1-2 are rotationally connected by spring hinge 1-3, on connector 1-2, be provided with connecting screw hole 1-2-1, the setting that curves inwardly of the lower end of each blade 1-1, its angle that curves inwardly is less than 90 degree; Described lower cover 2 comprises presses wall 2-1, spring 2-2 and pocket wall 2-3, spring 2-2 is arranged on and presses wall 2-1 upper surface, pocket wall 2-3 is arranged on and presses wall 2-1 lower end, press wall 2-1 and spring 2-2 to be arranged on upper press cover 1 inner side, the lower end that pocket wall 2-3 is each blade 1-1 by the lower end of upper press cover 1 catches, and the shape of pocket wall 2-3 and upper press cover 1 lower end coincide.
Preferably, the lower end of each blade 1-1 of described upper press cover 1 angle that curves inwardly is 45 degree.
Using method and the principle of invention: first the inflating expanded parabolic antenna of fin-plate type after curling folding is enclosed within on lower cover 2, the spring 2-2 upper end of lower cover 2 is against the lower surface of central dram, surround downwards with each blade 1-1 of upper press cover 1 again, be enclosed within the inflating expanded parabolic antenna of the fin-plate type outside after curling folding, and the lower end of each blade 1-1 is placed on to side compression in the pocket wall 2-3 of lower cover 2, now need the inflating expanded parabolic antenna of fin-plate type after curling folding to compress, also need spring 2-2 to lower compression, then by screw, the connector 1-2 of upper press cover 1 is connected with the central dram of the inflating expanded parabolic antenna of fin-plate type after curling folding at connecting screw hole 1-2-1 place, finally use blasting bolt that lower cover 2 is connected with the central dram of the inflating expanded parabolic antenna of fin-plate type after curling folding, the inflating expanded parabolic antenna of fin-plate type after curling folding is loaded in the space forming between upper press cover 1 and lower cover 2 also compacted.
Need to launch before the inflating expanded parabolic antenna of fin-plate type, only need to ignite blasting bolt, lower cover 2 can be flicked by spring 2-2, after lower cover 2 is flicked, blade 1-1 upwards launches under the elastic force of spring hinge 1-3, and the inflating expanded parabolic antenna of fin-plate type just can carry out the inflating expanded operation of Denging.
