The antenna surface 3 contacts with the roller 7-3 in the process of moving downwards around the pitching axis of the azimuth rotating platform 2, and the inner surface of the antenna continues to move downwards so that the auxiliary reverse main body 7-1 rotates around the hinge axis 8.
The antenna surface 3 is also hinged with the azimuth rotating platform 2, and the antenna surface 3 and the supporting frame can rotate around the pitching axis at the same time.
A gas spring 9 is also obliquely arranged between the antenna surface 3 and the support frame, one end of the gas spring 9 is hinged with the inner surface of the antenna surface 3, the other end of the gas spring is hinged with the upper surface of the support frame, and preferably, the number of the gas springs is two, and the gas springs are symmetrically arranged generally.
The top end of the hinge part 52 is provided with a secondary reverse stopper 53 for preventing the secondary reverse side main body 7-1 from continuing to turn over. A storage limiting block 6 is arranged below the bracket body 5, and the storage limiting block 6 is fixed on the roof and used for limiting the rotation limit position of the bracket body 5.
The azimuth rotating platform 2 and the storage limiting block 6 are fixed on the roof. The pitching axis of the azimuth rotation platform 2 passes through the inner hole of the supporting arm of the antenna surface 3 arranged on the antenna surface 3, and simultaneously passes through the pitching rotation hole 51 of the supporting frame to form two rotation hinges. One end of the air spring 9 is connected with the small lugs of the antenna surface 3 to form a hinge, and the other end is connected with the lugs on the upper surface of the support frame to form a hinge. The azimuth rotating platform 2, the antenna surface 3, the supporting frame and the gas spring 9 form a four-bar linkage.

As shown in fig. 1 and 2, the specific process of collecting the offset feed antenna is as follows: the antenna surface 3 moves downwards around the pitching axis of the azimuth rotating platform 2, the air spring 9 presses the supporting frame downwards by means of spring force in the movement, and when the supporting frame contacts the collecting limiting block 6, the supporting frame stops moving. The antenna surface 3 continues to move downward around the pitch axis of the azimuth rotation platform 2, and the gas spring 9 is compressed, shortening the length. The antenna surface 3 continues to move downwards around the pitch axis of the azimuth rotary platform 2, and the front end of the inner surface of the antenna contacts the roller 7-3. The antenna surface 3 continues to move downwards around the pitching axis of the azimuth rotation platform 2, and the auxiliary sub-assembly 7 starts to rotate around the hinge shaft 8 under the thrust of the inner surface of the antenna surface 3, and meanwhile, the roller 7-3 rotates (the roller 7-3 rolls along the inner surface of the antenna, so that the inner surface of the antenna can be protected from being damaged by sliding friction). The antenna surface 3 continues to move downwards around the pitch axis of the azimuth rotary platform 2 up to the stowed limit position.

The turning is not stopped until the leg of the sub-reverse side main body 7-1 is limited by the sub-reverse stopper 53 of the support frame (limit on the sub-reverse mounting block). The antenna surface 3 continues to move upwards around the pitching axis of the azimuth rotating platform 2, the air spring 9 continues to stretch, when the air spring 9 stretches to the limit length, the antenna surface starts to pull the supporting frame through the air spring 9, the supporting frame starts to leave the collecting limiting block 6, and the antenna is thoroughly unfolded.
At the same time, the air spring 9, the torsion spring and the auxiliary counter-limiting block 53 work together to keep the relative correct positions of the various parts of the antenna. At this time, the antenna can normally transmit and receive signals.
According to the embodiment, the height of the antenna is reduced to a great extent, the passing capacity of the antenna after loading is improved, the main finger pair can rotate downwards, and the antenna is positioned by the limiting block due to the fact that the torsion of the spring returns to the position during working.
