[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 6 The diagram shows a main support structure for a near-Earth satellite communication antenna, including a support base 1, a feed component 2 mounted on the support base 1, adjusting rods 3 rotatably mounted on both sides of the support base 1, a support portion 4 rotatably mounted on the outer side of the adjusting rods 3, a locking unit 5 for locking and limiting the support portion 4 mounted on the adjusting rods 3, a driving component 6 mounted on the support base 1 for moving the support base 1, and a connecting portion 7 adapted to and connected to the support portion 4 to extend the length of the support portion 4 so as to surround the outer side of the rod, with a connecting member 8 installed between two adjacent connecting portions 7.

[0033] In this scheme, the support part 4 and the connecting part 7 are connected to form a ring shape, which can be wrapped around the outside of the pole. In conjunction with the driving part 6, the support seat 1 and the feed part 2 can be moved up along the pole to realize the climbing operation, which facilitates the signal reception of the feed part 2.

[0034] After the support part 4 is separated from the connecting part 7, the angle of the support part 4 is adjusted so that the support part 4 is in an inclined state. With the help of the locking unit 5, the support part 4 is positioned, thereby completing the support of the bearing seat 1 and the feed component 2, which is convenient for placing on the ground for model reception.

[0035] After the support part 4 is separated from the connecting part 7, the personnel rotate the support part 4 until it fits against the support seat 1, and then lock the support part 4 in place by the locking unit 5, thereby achieving storage and making it convenient for personnel to carry.

[0036] For further details, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 11 The support part 4 includes a support plate 9 that is rotatably sleeved with the adjusting rod 3. The outer end of the support plate 9 is fixed with a mating plate 10 that is opposite to the connecting part 7. The mating plate 10 is provided with a mating groove 11. The support plate 9 is internally threaded with a screw rod 12. The outer end of the screw rod 12 is rotatably mounted with a ball bearing.

[0037] Also see Figure 3 , Figure 4 and Figure 11The connecting part 7 includes a connecting plate 13. One end of the connecting plate 13 is fixed with a docking rod 14 that is adapted to the docking groove 11, and the other end is provided with an opening 15. A plug rod 16 is inserted into the opening 15. The plug rod 16 is rotatably sleeved with a connecting post 17 at the opening 15. A docking cap 18 is threaded onto the top of the plug rod 16. A screw 19 is threaded into the connecting plate 13. A ball bearing is provided at the outer end of the screw 19.

[0038] Meanwhile, the connector 8 includes a connecting rod 20, one end of which is fixed with an end plate 21, a retaining ring 22 is sleeved on the outside of the connecting rod 20, and a buffer spring 23 is sleeved on the outside of the connecting rod 20 to abut against the end plate 21 and the retaining ring 22. One end of the connecting rod 20 passes through two connecting posts 17 in sequence and is locked with a nut threaded on it.

[0039] The principle of the connecting part 7 moving up and down around the outside of the rod after docking with the support part 4 is as follows: First, the operator inserts the docking rod 14 at one end of the connecting plate 13 into the docking groove 11. Then, the two connecting plates 13 and the two support plates 9 are rotated to fit together on the rod in a ring. After that, the operator inserts one end of the connecting rod 20 into the two connecting posts 17 in sequence, so that the abutment ring 22 abuts against the outside of one of the connecting posts 17. The other end of the connecting rod 20 is then tightened and fixed with a nut, so that the balls on the inner side of the connecting plate 13 and the support plate 9 abut against the outer wall of the rod. Then, under the action of the driving component 6, power is provided so that the bearing seat 1 can move up and down along the rod.

[0040] It should also be noted that the buffer spring 23 on the outside of the connecting rod 20 can provide a buffering effect, making the abutment ring 22 and the outside of the connecting post 17 fit together more tightly and more stably.

[0041] For further details, please refer to [link / reference]. Figure 9 The drive component 6 includes a dual-axis motor 24 mounted on the bottom of the support base 1 and a drive rod 25 mounted on the bottom of the support base 1 via a bearing seat. Rollers 26 are fixed to both output ends of the dual-axis motor 24 and both ends of the drive rod 25. A linkage component 27 is mounted on the drive rod 25.

[0042] The linkage 27 includes synchronous gears 28 fixed on the drive rod 25 and the output end of the dual-axis motor 24, and synchronous belts 29 are meshed on the outer sides of the two synchronous gears 28.

[0043] The principle of the drive component 6 providing power to move the support seat 1 upward is as follows: the operation of the dual-axis motor 24 causes the rollers 26 at both ends of the dual-axis motor 24 to rotate synchronously. During the rotation, the synchronous belt 29 drives the two synchronous gears 28 to rotate synchronously, thereby causing the drive rod 25 to rotate synchronously. This causes the two rollers 26 on the drive rod 25 to rotate. With the support part 4 and the connecting part 7 encircling the rod, and with the ball bearings fitting against the outer wall of the rod, the rod can move up and down on the outside. This allows the support seat 1 and the feed component 2 to move up and down, facilitating signal reception after climbing to a higher position.

[0044] For further details, please refer to [link / reference]. Figures 9-11 The locking unit 5 includes two moving blocks 30. The outer side of the adjusting rod 3 is engraved with a bidirectional threaded groove. The two moving blocks 30 are respectively threaded onto the two ends of the adjusting rod 3. Two compression springs 31 are respectively fitted onto the two ends of the adjusting rod 3. The two compression springs 31 are respectively fixed to the outer side of the two moving blocks 30. The outer ends of the two compression springs 31 are each fixed with a locking ring 32 fitted onto the outer side of the adjusting rod 3. A locking rod 33 is fixed to the outer side of the locking ring 32. Multiple locking grooves 34 are opened on the outer side of the support plate 9. A limiting strip 36 that slides and engages with the moving blocks 30 and the locking ring 32 is fixed to the outer side of the bearing seat 1. A rotating cap 35 is fixed to the outer end of the adjusting rod 3.

[0045] The locking unit 5 achieves its locking effect by rotating the cap 35, causing the adjusting rod 3 to rotate accordingly. This causes the two moving blocks 30 on the adjusting rod 3 to move in opposite directions, which in turn causes the compression spring 31 and the locking ring 32 to move outwards. This allows the locking rod 33 on the outer side of the locking ring 32 to engage with the locking groove 34 on the outer side of the support plate 9, thus achieving a locking and positioning effect. Similarly, rotating the cap 35 in the opposite direction causes the two moving blocks 30 to move closer to each other, causing the locking rod 33 to disengage from the locking groove 34. At this point, the operator can easily adjust the support plate 9 to rotate accordingly.

[0046] When the support base 1 is placed on the ground, the personnel only need to tilt the support plate 9 and then rotate the rotating cap 35 so that the locking rod 33 is locked in place with the locking groove 34, so that the support plate 9 remains tilted.

[0047] It should also be noted that the pole required in this invention can be a self-carried pole, a roadside street lamp, or a utility pole, etc.

[0048] Example 2: Please refer to Figures 5-8 This embodiment further explains the first embodiment, the difference being that the shape of the support base 1 is optimized so that the support plate 9 can occupy less space when stored.

[0049] Specifically, storage openings 37 are provided on both sides of the support plate 9 corresponding to the support seat 1. When the support plate 9 is rotated for storage, the personnel can rotate the support plate 9 into the storage opening 37, and then rotate the rotating cap 35 to make the locking rod 33 lock into the locking groove 34 for storage.

[0050] Example 3: Please refer to Figure 3 , Figure 5 and Figure 6 This embodiment further illustrates other embodiments, the difference being that the shape of the support base 1 is optimized to facilitate the storage of the connecting plate 13.

[0051] Specifically, the bearing seat 1 has two threaded holes 38 at both the front and rear ends for the insertion of the screw 19 when the connecting plate 13 is placed.

[0052] Personnel disassembled the connecting plate 13 from the support plate 9, and then... Figure 5 As shown, the screws 19 on the two connecting plates 13 are inserted into the threaded holes 38 on the front and rear ends of the bearing seat 1 to realize the storage and positioning of the connecting plates 13, making it easy for personnel to carry.
