[0027] The technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Referring to the drawings, Figures 1-2 The embodiments of the present application disclose a tower column bolt protective cap, comprising:

[0029] Cap body 1, the cap body 1 is formed through buckling cavity up and down, and the buckling cavity is adapted to the nut end of bolt;

[0030] The cap head 3 has an open lower end and its lower end face is fixedly connected to the upper end face of the cap body 1. The inner wall of the cap head 3 is provided with an internal thread 6, and the threaded end of the bolt can be threadedly connected to the internal thread 6.

[0031] The cap bottom 4 has a through connection at both ends, and its upper end face is fixedly connected to the lower end face of the cap body 1 with a washer for fastening bolts.

[0032] This implementation uses a cap bottom to fasten a gasket, a cap body to fasten the nut end of the bolt, and a cap head to connect with the threaded end of the bolt. Using this protective cap not only provides all-round protection for the tower bolts, but the threaded connection method also makes it easy to disassemble and reuse.

[0033] To further optimize the above technical solution and ensure that the protective cap can meet the needs of bolts of different lengths, it also includes a cap neck 2. The cap neck 2 is a conical structure with both ends through it. The end face of the large end of the cap neck 2 is fixed to the upper end face of the cap body 1. The outer wall of the cap head 3 is fixed to the inner wall of the cap neck 2 relative to its small end, and the lower end of the cap head 3 extends along the inner cavity of the cap neck 2.

[0034] The neck of the cap increases the height of the protective cap, allowing longer bolts to fully enter the cap head. For shorter bolts, since the lower end of the cap head extends along the inner cavity of the neck, the cap head only needs to have at least three threads align with the bolt to ensure a tight threaded connection between the protective cap and the bolt.

[0035] To further optimize the above technical solution and improve the structural rigidity and aesthetics of the protective cap, an annular convex rim 7 is fixed between the upper end face of the cap body 1 and the lower end face of the cap neck 2, and the lower end face of the cap head 3 is placed in the annular cavity of the convex rim 7.

[0036] To further optimize the above technical solution, reduce the manufacturing cost of the protective cap, and facilitate the connection between the cap head and the bolt, the cap body 1 is cylindrical and the cap head 3 is multifaceted prism.

[0037] like Figure 1 and 2 As shown, the cap head can be machined into a hexagonal prism, and the entire cap head can be used as a nut to facilitate the connection between the cap head and the bolt.

[0038] To further optimize the above technical solution and ensure that the cap bottom fully engages with the gasket, the inner diameter of the cap bottom 4 is larger than the inner diameter of the cap body 1. The height of the cap bottom 4 is greater than the thickness of the bolt gasket.

[0039] In the embodiment, the bottom 4 is cylindrical, the transition section 5 is conical and has two ends penetrating through, the end face of the large end of the transition section 5 is fixed with the upper end face of the bottom 4, and the outer wall of the lower end of the cap body 1 is fixed with the inner wall of the small end of the transition section 5. Since the inner diameter of the bottom is larger than the inner diameter of the cap body, the bottom covers the gasket and the cap body covers the nut end of the bolt, the manufacturing cost is reduced by the two structures with different inner diameters; the two structures are connected through the transition section, the structure is ingenious and the cost is low.

[0040] In order to further optimize the above technical scheme and improve the corrosion resistance of the protective cap, the outer periphery of the protective cap is coated with epoxy resin.

[0041] In order to further optimize the above technical scheme and improve the heat preservation and insulation performance of the protective cap, the outer periphery of the protective cap is coated with a ceramic heat insulation coating.

[0042] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same and similar parts of each embodiment can be referred to each other. For the device disclosed by the embodiments, since it corresponds to the method disclosed by the embodiments, the description is relatively simple, and the related parts can be referred to the method part.

[0043] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
