[0028] As Figures 1-3 shown, the embodiment of the present utility model provides a top cap for a regular polygon rod body. The rod body 20 includes a large-diameter outer end 21 and a small-diameter outer end 22, and the diameter gradually decreases from the large-diameter outer end 21 to the small-diameter outer end 22. The top cap includes a cap body 10 with a closed upper end and an open lower end. The closed upper-end setting can protect the top of the rod body 20 from external environment erosion, such as rainwater, ultraviolet rays, etc., extend the service life of the rod body 20, and can also improve the overall aesthetics of the rod body 20. The outer contour of the cap body 10 is circular and the outer diameter is equal everywhere to fit a hoop with the same outer contour being circular. The inner contour of the cap body 10 is in the shape of a regular polygon to fit the regular polygon rod body 20. Among them, the cap body 10 includes a large-diameter inner end 12 and a small-diameter inner end 11, and the inner diameter gradually decreases from the large-diameter inner end 12 to the small-diameter inner end 11. The large-diameter inner end 12 is located on one side of the small-diameter outer end 22, and the small-diameter inner end 11 is located on one side of the large-diameter outer end 21.
[0029] In the embodiment of the utility model, when in use, by setting the top cap on the top of the regular polygonal rod body 20 and applying force, the large diameter inner end 12 of the cap body 10 can be located on the side of the small diameter outer end 22 of the regular polygonal rod body 20, and the small diameter inner end 11 of the cap body 10 can be located on the side of the large diameter outer end 21 of the regular polygonal rod body 20, so that it is tightly fixed on the top of the regular polygonal rod body 20 with a polygonal cone structure that is small at the top and large at the bottom. The structure is simple, the installation is convenient, and it is not easy to slip. At the same time, the outer contour of the cap body 10 is circular, and it can also adapt to a hoop with the same circular outer contour to reduce the modification of the hoop, and there is no need to produce a regular polygonal hoop additionally, which reduces the research and manufacturing costs. It can be directly installed with an ordinary circular hoop on the market, which is highly practical.
[0030] Specifically, Figures 2-4 As shown, in the embodiment of the utility model, a plurality of release grooves 13 are provided on the outer wall of the cap body 10, which can make it easier for the cap body 10 to be inserted into the rod body 20, reducing the difficulty of installation. At the same time, the release grooves 13 can disperse the stress and avoid deformation or damage caused by stress accumulation due to thermal expansion and contraction during long-term use.
[0031] Specifically, Figures 2-4 As shown, in the embodiment of the utility model, the length of the cap body 10 is L1, and the length of the release groove 13 is L2, L2≤2 / 3L1, so as to ensure that the cap body 10 can provide sufficient elastic space during use, and the structural strength is not affected by the excessive length of the release groove 13. If the length of the release groove 13 is too long, the local strength of the top cap will decrease during use, affecting its overall performance. Therefore, by limiting the length of the release groove 13, it can be ensured that the top cap still maintains sufficient rigidity and stability when subjected to external loads.
[0032] Specifically, Figures 2-4 As shown, in the embodiment of the utility model, each of the release grooves 13 extends from the lower end opening of the cap body 10 along the upper end closed part, and the starting point of the release groove 13 is exactly located at the position where the cap body 10 contacts the rod body 20, so that it can be ensured that the cap body 10 can be smoothly inserted into the rod body 20, and the cap body 10 can be smoothly installed and disassembled even when the diameter of the rod body 20 changes.
[0033] Specifically, Figure 2 and Figure 5 As shown, in the embodiment of the utility model, each of the release grooves 13 is located at the connection position of the sides of the regular polygon. Since each corner of the regular polygon is a place where stress is concentrated, being set at the connection position of the sides of the regular polygon can effectively disperse these stresses, preventing the cap body 10 from being deformed or damaged due to excessive local stress, and at the same time having sufficient structural strength during use.
[0034] Specifically, as Figure 2 and Figure 5 shown, in the embodiment of the present utility model, the number of the release grooves 13 is M, and the number of sides of the regular polygon is N, where M < N, so as to avoid that too many release grooves 13 will weaken the overall structural strength of the cap body 10.
[0035] Specifically, as Figure 2 and Figure 5 shown, in the embodiment of the present utility model, the number of sides of the regular polygon is eight, the release grooves 13 are four, and the four release grooves 13 are arranged at the corners of the regular hexagon at an interval of one corner, that is, the release grooves 13 are symmetrically distributed in pairs at the corners of the regular polygon. Such a setting makes the structure of the release grooves 13 and the cap body 10 more symmetrical, so that the force is evenly distributed and the structure is stable.
[0036] Based on the above scheme, as Figure 2 and Figure 5 shown, in the embodiment of the present utility model, the inner wall of the cap body 10 is rounded at the corners of the regular polygon. The rounded corners 14 can enhance the thickness at the corners, thereby increasing the strength at the corners, making it not easy to be damaged. At the same time, it can make the installation of the cap body 10 smoother, play a guiding role, reduce friction, and make the installation process easier.
[0037] Based on the above scheme, as Figures 3-5 shown, in the embodiment of the present utility model, the top of the cap body 10 is a dome 15. The dome 15 is beneficial to the natural diversion of rainwater. The rainwater can flow away quickly along the smooth surface, reducing the possibility of water accumulation, thereby improving the waterproof performance. At the same time, it can reduce the wind resistance, reduce the impact force of the wind on the top cap, and better resist the influence of the wind.
[0038] Specifically, as Figure 2 and Figure 5 shown, in the embodiment of the present utility model, the inner contour of the cap body 10 is a regular octagon to adapt to the rod body 20 which is also a regular octagon. It should be understood that the number of sides of the regular polygon of the inner contour of the cap body 10 can be designed to change relatively according to the number of sides of different regular polygon rod bodies 20, and no limitation is made in the description of this embodiment. For example, in this embodiment, taking the rod body 20 with a regular octagon structure as an example, the inner contour of the corresponding cap body 10 is also a regular octagon structure.
[0039] Based on the above scheme, in the embodiment of the present utility model, the cap body 10 is integrally made of a composite material. While ensuring the structural strength, it is relatively light in weight, convenient for installation and transportation, and has good corrosion resistance, suitable for long-term outdoor use.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
