Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1-5 , the present utility model provides a technical solution: a high - strength wind - resistant structure of a lightning protection bracket, including a mounting base 1 for plugging and fixing the lightning rod 2. A fixing member is hinged to the top of the mounting base 1. There are two fixing members, and the two fixing members are screwed and sleeved outside the lightning rod 2. The bottom of the mounting base 1 is thread - connected with a connector 3. A lightning receiving rod is inserted inside the connector 3. A number of mounting rods 4 are fixed to the side of the mounting base 1 along the circumferential direction of the mounting base 1. An energy - releasing member is connected to the side of the mounting rod 4. The end of the mounting rod 4 away from the mounting base 1 is fixed with a support plate 5. The end of the support plate 5 away from the connecting rod is rotatably connected to a support seat 6. The other end of the support seat 6 is fixed with a support rod 7.

[0032] Among them, the energy release part includes a first connecting rod 9 rotatably connected to the side of the mounting rod 4, the first connecting rod 9 is slidably connected to a piston rod 10 at the end away from the mounting rod 4, the piston rod 10 slides inside the first connecting rod 9, the piston rod 10 is connected to a second connecting rod 11 at the end away from the first connecting rod 9, and the piston rod 10 slides inside the second connecting rod 11.

[0033] The second connecting rod 11 is hingedly connected with an ear piece 12 at the end away from the piston rod 10 . A first spring 13 is fixed inside the second connecting rod 11 . The other end of the first spring 13 is fixed at the end surface of the piston rod 10 .

[0034] Four mounting rods 4 are provided along the circumferential direction of the mounting seat 1, and each mounting rod 4 is connected to a first connecting rod 9 on its side. The first connecting rod 9 is connected to a piston rod 10 and a second connecting rod 11 at the end away from the mounting rod 4, and the second connecting rod 11 is bolted to the ground through an ear piece 12.

After the lightning rod 2 is installed, the second spring 16 can be used to abut the rubber plate 17 to the side of the lightning rod 2 to increase the installation stability of the lightning rod 2.

[0038] Meanwhile, the support plate 5 is in an inverted trapezoidal shape, and a spherical connection block 18 is fixed to the end of the support plate 5 facing the support seat 6 , and a spherical connection groove 19 for rotatably connecting the spherical connection block 18 is provided inside the support seat 6 .

[0040] Similarly, the vertical rod 22 can slide inside the sleeve 20. When the support plate 5 is tilted, the third spring 21 can be compressed. Then the third spring 21 has elastic potential energy, enabling the support plate 5 to reset. Combining with the above-mentioned first spring 13 structure, the wind resistance performance of the overall lightning protection bracket can be further improved.

[0041] The working principle of the present utility model: A lightning rod 2 can be inserted and installed inside the mounting seat 1, and at the same time, the lightning rod 2 is fixed by the side clamp 15. The bottom of the mounting seat 1 is used for inserting and connecting a lightning receiving rod.

After installation, the mounting seat 1 forms a first damping structure through the side first connecting rod 9, the piston rod 10, the second connecting rod 11 and the first spring 13. At the same time, the vertical rod 22, the sleeve 20 and the third spring 21 between the support plate 5 at the bottom of the mounting seat 1 and the support base 6 form a second damping structure. Then the mounting seat 1 and the support plate 5 can both rotate freely in the 360° direction, and the above two damping structures are used for buffering and energy release to effectively resist wind force.
