[0022] like Figures 1 to 4 As shown, the utility model is a lightning protection grounding network, comprising: a lightning protection pier 1, a support column 2 plugged into the top of the lightning protection pier 1, a support rod 3 plugged into the inner cavity of the support column 2, and an installation mechanism for installing the lightning protection grounding network body;

[0023] The mounting mechanism includes: a rectangular frame 4 rotatably mounted on the top of the support rod 3, a threaded rod 5 threadedly mounted on the top of the rectangular frame 4, a rotating plate 6 fixedly mounted on the top of the threaded rod 5, a linkage plate 7 rotatably mounted on the bottom of the threaded rod 5, an extrusion plate 9 symmetrically fixedly mounted on the bottom of the linkage plate 7, a clamping plate 10 slidably mounted on the bottom of the inner cavity of the rectangular frame 4, and a linkage spring 11 fixedly mounted between the clamping plate 10 and the inner wall of the rectangular frame 4;

[0024] The lightning protection grounding grid body can be installed through the installation mechanism. Since the lightning protection grounding grid body is composed of multiple horizontal steel bars and longitudinal steel bars, one end of the steel bar is inserted into the inner cavity of the rectangular frame 4 and is located between the two linkage springs 11. At this time, by rotating the rotating plate 6, the threaded rod 5 is driven to rotate by the rotating plate 6, and the linkage plate 7 is driven to move downward by the rotating plate 6. The two extrusion plates 9 are driven to move downward by the linkage plate 7. The two extrusion plates 9 can squeeze the adjacent clamping plates 10. The inclined surface of the extrusion plate 9 contacts the inclined surface of the adjacent clamping plates 10, which can drive the adjacent clamping plates 10 to move inward. The two clamping plates 10 move inward, and the steel bars can be clamped and fixed by the inward movement of the two clamping plates 10, and the linkage spring 11 is stretched, so that the device can quickly install the lightning protection grounding grid body.

[0025] When the rotating plate 6 is rotated in the opposite direction, the threaded rod 5 is rotated by the rotating plate 6, and the connecting plate 7 is driven to move upward by the threaded rod 5, and the two extrusion plates 9 are driven to move upward by the interlocking plate 7, so that the two extrusion plates 9 have no extrusion effect on the adjacent clamping plates 10. At this time, the elastic force of the two interlocking springs 11 can drive the adjacent clamping plates 10 to move to both sides and reset, so that the two clamping plates 10 have no clamping and fixing effect on the steel bars, so that the device can quickly disassemble the lightning protection grounding grid body, thereby making the device quickly install and disassemble the lightning protection grounding grid body, effectively solving the problem of the complicated disassembly and assembly operation of the lightning protection grounding grid body caused by the mutual cooperation of the curved metal plate and the bolts to press the steel bars to the top of the pillar.

[0026] Since the adjacent sides of the two clamping plates 10 are designed to be V-shaped, it is convenient to clamp and fix steel bars of different diameters, thereby expanding the scope of use;

[0027] Furthermore, since the rectangular frame 4 is rotatably connected to the top end of the support rod 3, the orientation of the rectangular frame 4 can be easily adjusted to fix the transverse or longitudinal steel bars, thereby improving the flexibility of the device.

[0028] Slide blocks 8 are fixedly mounted on both sides of the linkage plate 7. A slide groove is provided on the inner wall of the rectangular frame 4, and the slide blocks 8 are located in the inner cavity of the slide groove.

[0029] By sliding the slider 8 in the inner cavity of the slide groove, the linkage plate 7 can be limited, thereby preventing the linkage plate 7 from rotating with the threaded rod 5, thereby allowing the linkage plate 7 to maintain vertical linear movement.

[0030] A limit block 18 is fixedly installed at the bottom of the clamping plate 10, and a limit groove is provided at the bottom of the inner cavity of the rectangular frame 4. The limit block 18 is located in the inner cavity of the limit groove. A fixing rod 12 is installed through the side wall of the limit block 18. Both ends of the fixing rod 12 are fixedly installed on the inner wall of the limit groove.

[0031] By cooperating with the limiting block 18, the fixing rod 12 and the limiting groove, the clamping plate 10 can be limited, thereby preventing the clamping plate 10 from deviating during movement, thereby allowing the clamping plate 10 to maintain left and right linear movement.

[0032] A plurality of blind holes are provided on one side of the support rod 3, and the blind holes are linearly arranged from top to bottom. A plug-in tube 13 is connected to one side of the support column 2, and a connecting rod 14 is installed on the plug-in tube 13. One end of the connecting rod 14 is inserted into the inner cavity of the blind hole, and the other end of the connecting rod 14 is fixedly installed with a connecting block 15. A movable block 16 is fixedly sleeved on the outer edge of the connecting rod 14. A plug-in spring 17 is fixedly installed between the movable block 16 and the inner wall of the plug-in tube 13. The plug-in spring 17 is sleeved on the outer edge of the connecting rod 14.

[0033] By pulling the connecting block 15, the connecting block 15 drives the connecting rod 14 to move, so that the connecting rod 14 is separated from the adjacent blind hole cavity, and the movable block 16 is moved by the connecting rod 14, and the plug spring 17 is compressed by the movable block 16. At this time, the support rod 3 can be pulled upward, so that the height of the device can be adjusted according to the needs of use. The operation is simple and fast, which improves the applicability of the device. When the height adjustment is completed, the connecting block 15 is released, and the movable block 16 can be driven to reset by the elastic force of the plug spring 17. The connecting rod 14 is reset by the movable block 16, so that the connecting rod 14 is plugged into the adjacent blind hole cavity again, which makes it easy to fix the position of the support rod 3, and then the height of the device can be locked after adjustment.

[0034] Working principle: When in use, by pulling the connecting block 15, the connecting block 15 drives the connecting rod 14 to move, so that the connecting rod 14 is separated from the adjacent blind hole cavity, and the movable block 16 is moved by the connecting rod 14, and the plug spring 17 is compressed by the movable block 16. At this time, the support rod 3 can be pulled upward, so that the height of the device can be adjusted according to the needs of use. The operation is simple and fast, which improves the applicability of the device. When the height adjustment is completed, by loosening the connecting block 15, the movable block 16 can be driven to reset by the elastic force of the plug spring 17, and the connecting rod 14 is driven to reset by the movable block 16, so that the connecting rod 14 is plugged into the adjacent blind hole cavity again, so that the height adjustment is completed. It is convenient to fix the position of the support rod 3, and then the height of the device can be locked after adjustment. At this time, the lightning protection grounding grid body can be installed through the installation mechanism. Since the lightning protection grounding grid body is composed of multiple horizontal steel bars and longitudinal steel bars, one end of the steel bar is inserted into the inner cavity of the rectangular frame 4 and is located between the two linkage springs 11. At this time, by rotating the rotating plate 6, the threaded rod 5 is rotated by the rotating plate 6, and the linkage plate 7 is driven to move downward by the rotating plate 6. The two extrusion plates 9 are driven to move downward by the linkage plate 7. The adjacent clamping plates 10 can be squeezed by the two extrusion plates 9. The inclined surface of the extrusion plate 9 contacts the inclined surface of the adjacent clamping plates 10, which can be brought The adjacent clamping plates 10 are moved inwardly. By moving the two clamping plates 10 inwardly, the steel bars can be clamped and fixed, and the linkage spring 11 is stretched, so that the device can quickly install the lightning protection grounding grid body. When the rotating plate 6 is rotated in the opposite direction, the threaded rod 5 is rotated by the rotating plate 6, and the linkage plate 7 is driven to move upward by the threaded rod 5. The two extrusion plates 9 are driven to move upward by the linkage plate 7, so that the two extrusion plates 9 have no extrusion effect on the adjacent clamping plates 10. At this time, the elastic force of the two linkage springs 11 can drive the adjacent clamping plates 10 to move to both sides and reset, so that the two clamping plates 10 have no clamping and fixing effect on the steel bars. This allows the device to quickly disassemble the lightning protection grounding grid body, and thus allows the device to quickly install and disassemble the lightning protection grounding grid body, effectively solving the problem of the steel bars being pressed against the top of the pillar by the cooperation of the arc-shaped metal plate and the bolts, resulting in a relatively cumbersome disassembly and assembly operation of the lightning protection grounding grid body. Since the side where the two clamping plates 10 are close to each other is designed to be V-shaped, it is convenient to clamp and fix steel bars of different diameters, thereby expanding the scope of use. Moreover, since the rectangular frame 4 and the top end of the support rod 3 are rotatably connected, the direction of the rectangular frame 4 can be easily adjusted to fix the horizontal steel bars or the longitudinal steel bars, thereby improving the flexibility of the device.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
