[0026] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

Therefore, they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose of the present invention. At the same time, terms such as "upper", "lower", "left", "right", "middle", and "one" cited in the present specification are only for the convenience of description and are not intended to limit the applicable scope of the present invention. Changes or adjustments in their relative relationships should also be considered as the applicable scope of the present invention without substantially changing the technical content.

[0028] like Figure 3-5 As shown, an embodiment of the present invention provides an automatic antenna feed system, comprising a base 10, a lifting rod 20, a falling mechanism 30 and an antenna 40 arranged in sequence from bottom to top, and a wire-reeling mechanism 50 is provided on the lifting rod 20, and the falling mechanism 30 rotates as the lifting rod 20 is lifted and lowered to drive the antenna 40 to fall or stand up in a vertical plane. It should be understood that the above-mentioned wire-reeling mechanism 50 is a conventional device in the field. For example, the wire-reeling mechanism 50 can be a spiral spring cable, a reel-shaped winding drum, a box-type wire-reeling box, etc. Since the present invention does not make any improvements thereto, its specific structure and working method will not be described in detail here.

[0029] In the present invention, on the basis of the traditional automatic antenna feed system, the control of the retracting mechanism 30 is changed from electrical control to mechanical control, and the upper antenna 40 on the retracting mechanism 30 is retracted and erected by the same linkage with the power of the descending lifting rod 20, thereby reducing the control box and integrated cables (to control the retracting mechanism 30) and other components.

[0030] Specifically, such as Figure 4-5 As shown, in an embodiment of the present invention, the falling mechanism 30 includes a horizontally extending rotating shaft 31, a gear 32 arranged on the rotating shaft 31, and a rack 33 engaged with the gear 32 for transmission. The antenna 40 is fixedly mounted on the rotating shaft 31, and the rack 33 is arranged on the pipe sleeve 21 at the top end of the lifting rod 20. The up and down movement of the rack 33 drives the gear 32 to rotate, thereby driving the rotating shaft 31 to rotate.

[0031] During specific operation, when the lifting rod 20 descends, the pipe sleeve 21 at the top drives the rack 33 to move downward. When the rack 33 moves downward, it drives the rotating shaft 31 to rotate through the meshing transmission with the gear 32. The rotation of the rotating shaft 31 causes the antenna 40 to gradually fall from a vertical state to a horizontal state; when the lifting rod 20 rises, the pipe sleeve 21 at the top drives the rack 33 to move upward. When the rack 33 moves upward, it drives the rotating shaft 31 to rotate in the opposite direction through the meshing transmission with the gear 32. The reverse rotation of the rotating shaft 31 causes the antenna 40 to gradually rise from a horizontal state to a vertical state.

[0032] Specifically, such as Figure 4-5As shown, in the embodiment of the present invention, a rotating arm 34 is fixedly mounted on the rotating end of the rotating shaft 31, the rotating arm 34 is perpendicular to the rotating shaft 31, and at least one mounting plane parallel to the rotating end is provided on the rotating arm 34, and the antenna 40 is mounted on the mounting plane. By mounting the antenna 40 on the mounting plane of the rotating arm 34, the stability of the antenna 40 during the process of falling down and erecting is ensured, and shaking and vibration are reduced. The design of the mounting plane parallel to the rotating end enables the antenna 40 to maintain good balance during the rotation process.

[0033] During specific operation, when the lifting rod 20 descends, the rack 33 drives the gear 32 to rotate, and then drives the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 causes the rotating arm 34 and the antenna 40 thereon to gradually fall from a vertical state to a horizontal state; when the lifting rod 20 rises, the rack 33 drives the gear 32 to rotate in the opposite direction, and the rotating shaft 31 also rotates in the opposite direction. The reverse rotation of the rotating shaft 31 causes the rotating arm 34 and the antenna 40 thereon to gradually rise from a horizontal state to a vertical state.

[0034] Based on the above scheme, in an embodiment of the present utility model, a torsion spring is installed on the rotating shaft 31. When the lifting rod 20 descends, the torsion spring is compressed or twisted to store energy. When the lifting rod 20 rises, the torsion spring releases the stored energy, and the auxiliary antenna 40 returns to a vertical state from a horizontal state.

[0035] During specific operation, when the lifting rod 20 descends, the rack 33 moves downward, driving the gear 32 to rotate. The rotation of the gear 32 causes the inverted rotating shaft 31 to rotate, and the antenna 40 gradually inverts to a horizontal state. At the same time, the torsion spring is twisted or compressed to store energy; when the lifting rod 20 rises, the rack 33 moves upward, driving the gear 32 to rotate in the opposite direction. The reverse rotation of the gear 32 causes the inverted rotating shaft 31 to rotate in the opposite direction, and the antenna 40 gradually stands up to a vertical state. The torsion spring releases the stored energy to assist the antenna 40 in the erection process.

[0036] Specifically, such as Figure 3 As shown, in an embodiment of the present invention, the lifting rod 20 includes a multi-level hollow rod that can be lifted and lowered vertically, and the bottom end surface of the multi-level hollow rod is fixed on the base 10, which is used to provide stable support for the lifting and lowering of the antenna 40; the falling mechanism 30 is arranged at the top end of the multi-level hollow rod, wherein the lifting rod 20 is composed of a multi-level hollow rod, and each level of hollow rod can be nested in the next level of hollow rod. The extension and retraction of the multi-level hollow rod can be controlled by electric or manual means, thereby adjusting the height of the antenna 40, and the design of the hollow rod not only reduces the overall weight, but also provides internal space for laying cables and other equipment.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
