[0029] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0030] like Figure 1-Figure 7 As shown, a hemispherical skeleton that is easy to assemble includes a hemispherical skeleton 1.

[0031] Specifically, the hemispherical frame 1 includes a first linear support bar 11, a second linear support bar 12, and a third linear support bar 13, each of which is provided in a plurality of positions, and two first curved support bars 14, a second curved support bar 15, and a third curved support bar 16, each of which is provided in a plurality of positions and spaced apart in the middle. The structure between each support bar is described in more detail below.

[0032] Among them, such as Figure 4 As shown, the first, second, and third linear support bars 11, 12, and 13 overlap and form a "M"-shaped arrangement. This "M"-shaped arrangement ensures the bottom stability of the hemispherical frame 1, preventing it from shaking.

[0033] Specifically, if Figure 5-Figure 7 As shown, the ends of the two first curved support bars 14 are connected to the ends of the first linear support bar 11; the ends of the two second curved support bars 15 are connected to the ends of the second linear support bar 12; and the ends of the two third curved support bars 16 are connected to the ends of the third linear support bar 13. Simultaneously, the middle portions of the two first curved support bars 14 are connected to the middle portions of the two second curved support bars 15 and the middle portions of the two third curved support bars 16, respectively. The middle portions of the two second curved support bars 15 are also connected to the middle portions of the two third curved support bars 16. Therefore, the curved support bars are interconnected to ensure the stability of the hemispherical frame 1.

[0034] More specifically, if Figure 1 、 Figure 2 and Figure 7 As shown, two first curved support bars 14, two second curved support bars 15, and two third curved support bars 16 are evenly distributed on both sides of the central axis of the hemispherical frame 1, so that a hollow area 3 is formed in the middle of the upper end of the hemispherical frame 1. Therefore, after the above arrangement, the stability of the hemispherical frame 1 can also be ensured.

[0035] Depend on Figure 1 As shown, each arc-shaped support bar is located above each straight support bar.

[0036] like Figure 1 、 Figure 2 and Figure 7 As shown, in this embodiment, the intersection of the first, second, and third linear support bars 11, 12, and 13 is located on the central axis of the hemispherical frame 1, resulting in an even distribution of the linear support bars, ensuring the support stability of the hemispherical frame 1. Furthermore, the intersection of the first, second, and third linear support bars 11, 12, and 13 is located directly below the hollow region 3, further optimizing the distribution of the linear support bars and the arcuate support bars. Furthermore, the central axis of the hemispherical frame 1 coincides with the central axis of the hollow region 3.

[0037] In this embodiment, the first linear support bar 11 , the second linear support bar 12 and the third linear support bar 13 are of equal length.

[0038] In this embodiment, the lengths of the first arc-shaped support bar 14 , the second arc-shaped support bar 15 and the third arc-shaped support bar 16 are also equal.

[0039] like Figure 1 As shown in the embodiment, the first arc-shaped support bar 14, the second arc-shaped support bar 15, and the third arc-shaped support bar 16 are all semi-annular. However, those skilled in the art will appreciate that the shape of the arc-shaped support bar can be adjusted to suit actual needs, which will not be further elaborated here.

[0040] Preferably, each connection point between the first linear support bar 11, the second linear support bar 12, the third linear support bar 13, the first curved support bar 14, the second curved support bar 15, and the third curved support bar 16 is connected by binding. Furthermore, to improve stability, each connection point between the first linear support bar 11, the second linear support bar 12, the third linear support bar 13, the first curved support bar 14, the second curved support bar 15, and the third curved support bar 16 can also be fixedly connected using a combination of adhesive tape and cable ties. Specifically, during assembly, each connection point is first secured with adhesive tape and then secured with cable ties, thereby achieving a very secure positioning structure.

[0041] As a first embodiment, the first linear support bar 11 , the second linear support bar 12 , the third linear support bar 13 , the first arcuate support bar 14 , the second arcuate support bar 15 and the third arcuate support bar 16 can all be made of solid fiberglass rods.

[0042] As a second embodiment, the first linear support bar 11 , the second linear support bar 12 , the third linear support bar 13 , the first arcuate support bar 14 , the second arcuate support bar 15 and the third arcuate support bar 16 may all be hollow glass fiber tubes.

[0043] As a third embodiment, the first linear support bar 11, the second linear support bar 12, the third linear support bar 13, the first arc support bar 14, the second arc support bar 15 and the third arc support bar 16 can all be made of stainless steel, galvanized steel pipes, steel bars or elastic steel wires.

[0044] Therefore, the specific materials of each linear support bar and each arc-shaped support bar can be selected according to actual needs and are not specifically limited here.

[0045] From the above description, it can be seen that the first linear support bar 11, the second linear support bar 12 and the third linear support bar 13 serve as the bottom of the hemispherical skeleton 1, while the first arc support bar 14, the second arc support bar 15 and the third arc support bar 16 serve as the top of the hemispherical skeleton 1.

[0046] The following describes the installation steps of the utility model in order to understand the utility model:

[0047] Step 1: If Figure 3 As shown, the first linear support bar 11 and the second linear support bar 12 are positioned;

[0048] Step 2: If Figure 4As shown, the third linear support bar 13 is positioned and the first linear support bar 11, the second linear support bar 12 and the third linear support bar 13 are connected to each other, and the first linear support bar 11, the second linear support bar 12 and the third linear support bar 13 are arranged in a "M" shape;

[0049] Step 3: If Figure 5 As shown, two first arc-shaped support bars 14 are assembled;

[0050] Step 4: If Figure 6 As shown, two second arc-shaped support bars 15 are assembled;

[0051] Step 5: If Figure 7 As shown, the two third arc-shaped support bars 16 are assembled, thereby completing the assembly of the hemispherical skeleton 1.

[0052] In summary, the hemispherical frame of the present invention comprises only a plurality of linear support bars and a plurality of curved support bars. Once these bars are assembled, the frame's overall structure is simple and assembly is very convenient. Furthermore, since only two types of support bars, linear and curved, are required for assembly, only two specifications of support bars need to be produced during manufacture, facilitating production and significantly improving efficiency.

[0053] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
