[0020] See also Figure 1-3 The utility model provides a technical solution: it includes a mounting base 4 and a lightning rod 2 connected to the top of the mounting base 4, a connecting column 16 is fixedly connected to the mounting base 4, the top of the connecting column 16 is fixedly connected to the body 5, the bottom of the connecting column 16 is fixedly connected to the base 1, the top of the body 5 is fixedly connected to the first limit block 6, the top of the first limit block 6 is slidably connected to the rocking arm 7, one end of the rocking arm 7 is rotatably connected to the second disc 9, one side of the first limit block 6 is slidably connected to the first disc 8, the top of the first disc 8 is fixedly connected to the first connecting block 10, and one side of the first connecting block 10 is fixedly connected to the handle 12.

[0021] It should be noted that a small circular hole is provided in the center of the mounting seat 4 to facilitate the ground wire 3 connected to the lightning rod 2 to pass through the mounting seat 4 to achieve stable placement of the lightning rod 2.

[0022] During the specific implementation, the lightning rod 2 is placed on the mounting base 4 fixedly connected to the base 1 through the connecting column 16, and the ground wire 3 at the bottom of the lightning rod 2 is passed through the mounting base 4, and the handle 12 is turned to clamp the lightning rod 2. The first connecting block 10 fixedly connected to the handle 12 and the first disc 8 move synchronously with the handle 12, and drive the second disc 9 threadedly connected to the first connecting block 10 through the first bolt 11 to rotate synchronously. During the movement of the second disc 9, the rocking arm 7 rotatably connected to the second disc 9 is driven to swing, and the other end of the rocking arm 7 is slidably arranged in the slide groove 18 on the first limit block 6. When the rocking arm 7 swings to a certain extent, one end of the multiple rocking arms 7 realizes the centering clamping function of the lightning rod 2.

[0023] For further information, see Figure 2 The middle part of the handle 12 is fixedly connected to a second limit block 13, the top of the second limit block 13 is movably connected to a limit column 14, and a limit hole 15 is provided at one end of the body 5, and the limit column 14 is plugged into the body 5 through the limit hole 15.

[0024] It should be noted that the handle 12 is only provided on one side in the same direction as the limiting hole 15 .

[0025] During specific implementation, in order to limit the rocking arm 7 that has swung to an appropriate position, a handle 12 is connected to one side of the first connecting block 10 in the same direction as the limiting hole 15, and a second limiting block 13 is fixedly connected to the handle 12 in the vertical direction opposite to the limiting hole 15. When the handle 12 is moved to the rocking arm 7 to clamp the lightning rod 2, the limiting column 14 is inserted into the top of the second limiting block 13 to limit the handle 12, thereby limiting the rocking arm 7.

[0026] For further information, see Figure 2 There are three first limit blocks 6, which are evenly spaced in a circular array around the center of the body 5. A slide groove 18 is provided on the top of the first limit block 6, and the rocker arm 7 is slidably connected to the first limit block 6 through the slide groove 18.

[0027] In specific implementation, in order to achieve stable sliding of the rocking arm 7, a sliding groove 18 is opened at the top of the first limit block 6. When the rocking arm 7 is synchronously driven by the movement of the second disc 9, the rocking arm 7 can achieve limited sliding in the first limit block 6 through the sliding groove 18.

[0028] For further information, see Figure 3 A circular arc groove is provided on the side of the first limit block 6 close to the first disc 8, and a circular ring with the same inner diameter as the first disc 8 is provided on the top of the body 5. The first disc 8 is rotatably connected to the body 5 at the top of the body 5.

[0029] During specific implementation, in order to ensure that the first disc 8 can only rotate around the axis of the body 5, an arc groove is opened on the side of the first limit block 6 close to the first disc 8, so that the edge of the first disc 8 is clamped in the arc groove, thereby increasing the stability of the rotational connection of the first disc 8 on the body 5. A circular ring with the same inner diameter as the first disc 8 is provided on the top of the body 5 to further fix the axis of the rotational movement of the first disc 8.

[0030] For further information, see Figure 2 There are three rocking arms 7 , both ends of which are disc-shaped. A second connecting block 19 is provided on the top of one end of the rocking arm 7 close to the second disc 9 , and the rocking arm 7 is rotatably connected to the second disc 9 through the second connecting block 19 .

[0031] In specific implementation, multiple rocking arms 7 are set up, and the lightning rod 2 is clamped when the lightning rod 2 is placed with one end of the rocking arm 7 facing the center of the second disc 9. The end of the rocking arm 7 close to the center of the second disc 9 is set to a disc shape to facilitate adaptation to lightning rods 2 of different diameters.

[0032] For further information, see Figure 2 The top of the second disc 9 is threadedly connected with a first bolt 11, and the first bolt 11 is located directly above the first connecting block 10. There are three first connecting blocks 10, which are evenly spaced in a circular array around the center of the second disc 9. The second disc 9 is threadedly connected to the first connecting block 10 through the first bolt 11.

[0033] In specific implementation, the first connecting blocks 10 are evenly spaced in a circular array at the center of the second disc 9, so that the second disc 9 is threadedly connected to the first connecting blocks 10 through the first bolts 11, and the rocking arm 7 is evenly spaced among the multiple first connecting blocks 10 to facilitate the rotation of the rocking arm 7.

[0034] For further information, see Figure 1 and Figure 3 The base 1 is threadedly connected with second bolts 17 , and there are four second bolts 17 , which are evenly spaced and arranged in a circular array around the center of the base 1 .

[0035] In specific implementation, second bolts 17 are evenly distributed in a circular array at the center of the base 1, so that the base 1 is fixedly connected to the outdoor switch through the second bolts 17, thereby improving the stability of the lightning protection mechanism installed on the outdoor switch.

[0036] For further information, see Figure 2 The limiting hole 15 is integrally formed with anti-slip lines, and one end of the limiting column 14 and the limiting hole 15 that are plugged into each other is sleeved with an anti-slip sleeve.

[0037] In specific implementation, in order to improve the stability when the limiting column 14 is plugged into the limiting hole 15, an integrally formed anti-slip pattern is provided in the limiting hole 15. When the limiting column 14 passes vertically downward through the second limiting block 13 until it is inserted into the limiting hole 15 on the body 5, stable limiting of the handle 12 is achieved.

[0038] Working principle: When installing the lightning protection mechanism for the outdoor switch, first place the base 1 on the selected installation position, then fix the base 1 on the outdoor switch by the second bolt 17, and then place the lightning rod 2 on the mounting base 4 fixedly connected to the base 1 through the connecting column 16, and pass the ground wire 3 at the bottom of the lightning rod 2 through the small hole opened in the center of the mounting base 4. After placing the lightning rod 2, turn the handle 12 to clamp the lightning rod 2. During the clamping process, the first connecting block 10 and the first disc 8 fixedly connected to the handle 12 move synchronously with the handle 12, and drive the first connecting block 10 and the first disc 8 through the first connecting block 10. The second disc 9 threadedly connected to the first connecting block 10 by the bolt 11 rotates synchronously. During the movement of the second disc 9, the rocking arm 7 connected to the second disc 9 through the second connecting block 19 is driven to swing. The other end of the rocking arm 7 is slid into the slide groove 18 on the first limit block 6. When the rocking arm 7 swings to a certain extent, one end of the multiple rocking arms 7 realizes the centering clamping function of the lightning rod 2. At this time, the limit column 14 is placed on the second limit block 13, and it is aligned with the limit hole 15 vertically downward until it is inserted into the body 5, completing the limitation of the handle 12.
