Abstract
The invention relates to a mast for connection of the tail end of a rib plate of an inflatable space antenna of a radial rib and an inflatable ring, belonging to the technical field of the inflatable space antenna of the radial ribs and aiming at overcoming the phenomenon that the mast for connection of the tail end of the rib plate of the inflatable space antenna of the existing radial rib and the inflatable ring cannot be connected with the rib plate and the inflatable ring easily, the connection firmness is poor, and the coil-folded diameter of the antenna is large. The mast comprises a hollow mast body with oval-shaped cross section, wherein a side plate connected with a pull rope of the inflatable ring is arranged at the rear side of the mast body, a clamping plate for clamping the rib plate is arranged at the front side of the mast body, the bottom of the clamping plate stretches into the mast body, a groove is formed in the middle of the clamping plate, the rib plate is inserted into the groove, and a cross-shaped reinforcing rib is arranged inside the mast body. The mast is used for connection of the tail end of the rib plate of the inflatable space antenna of the radial rib and the inflatable ring.
Description
Technical field
The invention belongs to radial rib inflatable space antenna technical field, be specifically related to a kind of radial rib inflatable space antenna floor tail end and be connected with inflation ring and use mast.
Background technology
The mast that current radial rib inflatable space antenna floor tail end is connected with inflation ring is simple cylindrical structure, not easily be connected with floor and inflation ring, easy generation connects unstable phenomenon, and cause antenna curling folding after diameter large, so need to improve.
Summary of the invention
The object of the invention is in order to solve current radial rib inflatable space antenna floor tail end to be connected with inflation ring with mast be not easily connected with floor and inflation ring, easy generation connects unstable phenomenon, and cause antenna curling folding after the large problem of diameter, provide a kind of radial rib inflatable space antenna floor tail end to be connected with inflation ring with mast, its technical scheme is as follows:
A kind of radial rib inflatable space antenna floor tail end is connected with mast with inflation ring, it comprises cross section and is ellipse and is the shaft of hollow; On rear side of shaft, be provided with the side plate connecting inflation ring stay cord, with stay cord be connected after can punching during use on side plate, side plate can also play the effect strengthened shaft; The clamping plate of clamping floor are provided with in the front side of shaft, the bottom of clamping plate extend into the inside of shaft, the groove inserting floor is provided with in the middle of clamping plate, groove extend into the inside of shaft, punch after floor tail end being inserted during use the groove in the middle of clamping plate again and to fix with rivet, clamping plate also can play the effect strengthened shaft; Cross reinforcement is provided with in shaft; This kind of radial rib inflatable space antenna floor tail end is connected with inflation ring uses mast entirety to adopt carbon fibre materials, and is integrated shape type structure.
Beneficial effect of the present invention is: easy for installation, firmly, under same intensity, oval shaft can obviously reduce antenna curling folding after diameter, and can ensure that floor tail end direction is axially consistent with shaft, applicable radial rib inflatable space antenna use.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the cross-sectional view of Fig. 1.
embodiment:
See figures.1.and.2, a kind of radial rib inflatable space antenna floor tail end is connected with mast with inflation ring, and it comprises cross section is oval and is the shaft 1 of hollow; On rear side of shaft 1, be provided with the side plate 2 connecting inflation ring stay cord, with stay cord be connected after can punching during use on side plate 2, side plate 2 can also play the effect strengthened shaft 1; The clamping plate 3 of clamping floor are provided with in the front side of shaft 1, the bottom of clamping plate 3 extend into the inside of shaft 1, the groove 3-1 inserting floor is provided with in the middle of clamping plate 3, groove 3-1 extend into the inside of shaft 1, punch after floor tail end being inserted during use the groove 3-1 in the middle of clamping plate 3 again and to fix with rivet, clamping plate 3 also can play the effect strengthened shaft 1; Cross reinforcement 4 is provided with in shaft 1; This kind of radial rib inflatable space antenna floor tail end is connected with inflation ring uses mast entirety to adopt carbon fibre materials, and is integrated shape type structure.
