[0003] The portable satellite antenna folding support frame and satellite antenna designed in this utility model can overcome the shortcomings of the existing satellite antenna support frames in terms of portability.

[0004] The purpose of this utility model is to provide a portable satellite antenna folding support frame, including a central cylinder. The first end of the central cylinder has a fixed connecting ring, which is arranged around the central axis of the central cylinder. A sliding connecting ring is sleeved on the outer wall of the central cylinder. The sliding connecting ring can be driven to slide back and forth along the central axis of the central cylinder. It also includes multiple diagonal braces and horizontal braces. The first end of each diagonal brace is hinged to the fixed connecting ring, and the second end of each diagonal brace is hinged to each support section. The first end of each horizontal brace is hinged to the sliding connecting ring, and the second end of each horizontal brace is hinged to each support section. When the sliding connecting ring is driven to slide toward the first end of the central cylinder to a first preset position, the support frame is in a stored state. When the sliding connecting ring is driven to slide toward the second end of the central cylinder to a second preset position, the support frame is in a used state, and the sliding connecting ring can be positioned at the first preset position or the second preset position.

[0005] In some embodiments, when the sliding connecting ring is in the second preset position, the cross brace is perpendicular to the central axis of the central cylinder; and / or, the sliding connecting ring has a positioning bolt.

[0006] In some embodiments, the number of diagonal braces, cross braces, and support sections is six.

[0007] In some embodiments, a circumferential support rod is connected between two adjacent support sections.

[0008] In some embodiments, the circumferential support rod includes a left rod and a right rod, the first ends of the left rod and the right rod being detachably connected, and the second ends of the left rod and the right rod being hinged to the support section corresponding to the position.

[0009] In some embodiments, the first ends of the left rod and the right rod are respectively positioned by a concave-convex interlocking structure.

[0010] In some embodiments, the diagonal brace is hinged to the fixed connecting ring and the support section, and the horizontal brace and the circumferential support rod are hinged to the support section by bolts.

[0025] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed.

[0026] The following example describes a portable satellite antenna folding support frame and satellite antenna of this utility model. This example is only a part of the embodiments of this utility model, but the protection scope of this utility model is not limited thereto. All other embodiments obtained by those skilled in the art without creative effort should be covered within the protection scope of this utility model.

[0027] Please refer to the reference. Figures 1 to 8 According to an embodiment of this utility model, a portable satellite antenna folding support frame is provided, including a central cylinder 3. The first end of the central cylinder 3 has a fixed connecting ring 2, which is arranged around the central axis of the central cylinder 3. In one specific embodiment, the aforementioned fixed connecting ring 2 is integrally formed or welded to the central cylinder 3. A sliding connecting ring 4 is sleeved on the outer wall of the central cylinder 3, and the sliding connecting ring 4 can be driven to slide back and forth along the central axis of the central cylinder 3. It also includes multiple diagonal braces 5 and horizontal braces 6. The first end of each of the diagonal braces 5 is hinged to the fixed connecting ring 2, and the second end of each of the diagonal braces 5 is respectively hinged to each of the support sections 9. The first end of each of the horizontal braces 6 is hinged to the sliding connecting ring 4, and the second end of each of the horizontal braces 6 is respectively hinged to each of the support sections 9. It can be understood that the aforementioned diagonal braces 5, horizontal braces 6, and support sections 9 together form a support rod assembly. When the sliding connecting ring 4 is driven to slide toward the first end of the central cylinder 3 to the first preset position, the support frame is in a retracted state (see...). Figure 2 As shown), when the sliding connecting ring 4 is driven (specifically, by applying manual force) to slide towards the second end of the central cylinder 3 to the second preset position, the support frame is in use (see...). Figure 1 As shown), the sliding connecting ring 4 can be positioned at the first preset position or the second preset position. In a specific embodiment, the aforementioned sliding connecting ring 4 has a positioning bolt 14 that can be screwed in to lock the relative position between the sliding connecting ring 4 and the central cylinder 3 when the sliding connecting ring 4 is adjusted to the corresponding position.

[0028] In this technical solution, the end faces of each diagonal brace 5 and horizontal brace 6 are hinged to the fixed connecting ring 2, the support section 9, and the sliding connecting ring 4. When the support frame is in use, the sliding connecting ring 4 is in the second preset position, which makes the diagonal brace 5, the horizontal brace 6, and the central cylinder 3 form a triangular support structure, thus improving the support stability of the support frame. At the same time, the sliding connecting ring 4 can be driven to switch and adjust between the first preset position and the second preset position, so that the aforementioned diagonal brace 5 and horizontal brace 6 can be close to the central cylinder 3 for storage, which greatly improves the portability of the support frame and makes the structure compact and easy to store.

[0029] In some embodiments, when the sliding connecting ring 4 is in the second preset position, the horizontal support rod 6 is perpendicular to the central axis of the central cylinder 3, that is, the triangle formed by the diagonal support rod 5, the horizontal support rod 6 and the central cylinder 3 is a right triangle with a right angle at the base, which makes the force distribution more reasonable and further improves the stability of the support frame.

[0030] In one specific embodiment, the number of diagonal braces 5, horizontal braces 6, and support sections 9 is six, which can provide high support stability in all directions. In a preferred embodiment, a circumferential support rod (not indicated in the figure) connects two adjacent support sections 9 to reinforce the spacing between adjacent sets of support components, further improving the overall stability of the support frame. It can be understood that when the aforementioned support components are set to six sets, six corresponding circumferential support rods are also set. In this case, from a top view, the outer edge of the support frame forms a regular hexagon. This structure of the support frame has absolute anti-tipping ability, that is, it has extremely high wind resistance.

[0031] See details Figure 1 and Figure 3 , Figure 4 As shown, in some embodiments, the circumferential support rod includes a left rod 7 (also called the left support rod) and a right rod 8 (also called the right support rod). The first ends of the left rod 7 and the right rod 8 are detachably connected by left and right rod fixing bolts 15. The second ends of the left rod 7 and the right rod 8 are respectively hinged to the support section 9 at the corresponding positions. This allows the left rod 7 and the right rod 8 to be disassembled and separated when the support frame needs to be stored, facilitating storage. Figure 4 As shown, because the second ends of the left rod 7 and the right rod 8 are hinged to the support section 9, the left rod 7 and the right rod 8 will not loosen even when stored, thus ensuring the integrity of the material.

[0032] In some embodiments, the first ends of the left rod 7 and the right rod 8 are respectively positioned by a concave-convex structure. The concave-convex structure specifically includes, for example, a protrusion formed on the first end of the left rod 7 and a groove formed on the first end of the right rod 8. The protrusion and the groove are inserted into each other, and the aforementioned left and right rod fixing bolts 15 lock the two together.

[0033] In some embodiments, the diagonal brace 5 is hinged to the fixed connecting ring 2 and the support section 9, and the horizontal brace 6 and the circumferential support rod are hinged to the support section 9 by bolts 16, so as to ensure the accuracy of the position of each member, prevent excessive displacement deviation, and make the support frame adjustable for uneven terrain.

[0034] In some embodiments, each support section 9 is further provided with a leveling component, which allows for adjustment of the overall levelness of the support frame. In one specific embodiment, the leveling component includes a leveling wheel 11 threadedly connected to the support section 9 and a universal support seat 10 hinged to the bottom end of the leveling wheel 11. A force-applying wheel is fixedly connected to the top end of the leveling wheel 11, and a support seat locking nut 12 is threadedly connected to the leveling wheel 11. A level 13 (e.g., a bubble level) is provided on the first end face of the central cylinder 3. When placing the support frame, the operator can visually adjust the overall levelness of each support section 9 using the leveling component provided with the level 13, saving installation and deployment time.

[0035] It is understandable that, since the support frame components in this utility model are mostly rod structures, they are relatively lightweight, and the best corresponding rod structure is a hollow cylinder.

[0036] According to an embodiment of the present invention, a satellite antenna is also provided, including the aforementioned portable satellite antenna folding support frame and a satellite antenna reflector 1 supported on the support frame. Specifically, the satellite antenna reflector 1 is detachably connected to the first end of the central cylinder 3 through a corresponding attitude adjustment mechanism (e.g., a pitch and rotation mechanism).

[0037] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
