Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figures 1-5 , a bottom fixing device for a lightning rod, comprising a mounting base 1, a fixing groove 2 is opened at the top of the mounting base 1, clamping blocks 3 are slidably connected to both sides inside the mounting base 1 and extend to the inside of the fixing groove 2, fixing frames 4 are fixedly connected to both sides of the top of the mounting base 1, clamping plates 5 are slidably connected inside the two fixing frames 4 through sliding rods, a rod body 6 is detachably connected to the top of the mounting base 1, an insertion block 7 is fixedly connected to the bottom of the rod body 6, card slots 8 matching with the clamping blocks 3 are opened on both outer sides of the insertion block 7, and a fixing component is arranged inside the mounting base 1.

[0022] Specifically, the fixing component includes a first spring 10 and a linkage unit. The first spring 10 is disposed inside the mounting base 1 and on one side of the clamping block 3. The interior of the mounting base 1 extends into the fixing groove 2 and is rotatably connected to a first lead screw 11. A threaded block 12 is threadedly connected to the outside of the first lead screw 11. Both sides inside the fixing groove 2 are fixedly connected with limiting rods 13. The threaded block 12 is slidably connected to the outside of the limiting rods 13. A second spring 14 is disposed between the mounting base 1 and the threaded block 12 on the outside of the first lead screw 11. The clamping plate 5 can be moved through the linkage unit. The linkage unit includes a first bevel gear 15. The first bevel gear 15 is fixedly connected to the bottom of the first lead screw 11. Both sides inside the mounting base 1 are rotatably connected with rotating shafts 16. One end of each of the two rotating shafts 16 is fixedly connected with a second bevel gear 17. The first bevel gear 15 is meshed and connected with the two second bevel gears 17 respectively. One end of each of the two rotating shafts 16 away from the second bevel gear 17 is fixedly connected with a first pulley 18. A second lead screw 19 is slidably connected inside the fixing frame 4. One end of the second lead screw 19 is fixedly connected with the clamping plate 5. A second pulley 20 is rotatably connected inside the fixing frame 4. The first pulley 18 and the second pulley 20 are connected by a transmission belt 21. A threaded ring 22 is fixedly connected to one side outside the second pulley 20. The threaded ring 22 is threadedly connected to the outside of the second lead screw 19.

[0023] Through the above technical solution, first, the support base 23 is installed at the corresponding working position through multiple bolts. When it is necessary to install and fix the lightning rod, first insert the rod body 6 into the inside of the fixing groove 2 through the insertion block 7 at the bottom. During the insertion process, the inclined surface at the top of the clamping block 3 can be pushed by the bottom of the insertion block 7, and the two clamping blocks 3 are pushed into the inside of the mounting seat 1. At the same time, the first spring 10 is compressed by the clamping block 3 until the insertion block 7 is completely inserted into the inside of the mounting seat 1. Then the clamping block 3 can bounce into the corresponding card slot 8 under the rebounding force of the first spring 10, and the rod body 6 can be fixed. And while the insertion block 7 descends, it can push the threaded block 12 to slide downward under the limitation of the limiting rod 13. The threaded block 12 drives the first lead screw 11 and the first bevel gear 15 to rotate through the threaded connection relationship, so that the first bevel gear 15 drives the two second bevel gears 17 and the corresponding rotating shafts 16 to rotate through the meshing relationship. The rotating shaft 16 drives the first pulley 18 on the other side to rotate, so that the first pulley 18 drives the corresponding second pulley 20 and the threaded ring 22 to rotate through the transmission belt 21. The threaded ring 22 drives the second lead screw 19 and the corresponding clamping plate 5 to slide inside the fixing frame 4 through the threaded connection relationship, so that the two clamping plates 5 move closer to each other until the two sides of the rod body 6 are clamped and fixed, thereby realizing the vertical reinforcement of the rod body 6, effectively avoiding the inclination and shaking of the rod body 6 caused by bad weather, which affects the stability and thus reduces the service life. This device can install and fix the lightning rod through the support base 23 and the mounting seat 1 set, which increases the contact area with the ground, thereby effectively improving the use stability. And while installing and fixing the lightning rod, it can drive the clamping plates 5 on both sides above the mounting seat 1 to vertically fix the lightning rod, effectively avoiding the inclination and shaking of the rod body 6 caused by the difficulty of supporting strong winds when encountering bad weather, thereby improving the service life of the rod body 6.

[0024] Specifically, one side of the outside of the clamping block 3 extends to the outside of the mounting seat 1 and is fixedly connected with a pull rod 9, and the pull rod 9 is slidably connected with the inner wall of the mounting seat 1.

[0025] Through the above technical solution, by pulling the pull rod 9, the corresponding clamping block 3 can be driven to slide out of the card slot 8, and the rod body 6 can be removed through the reverse process operation of the above principle, effectively improving the disassembly and assembly efficiency.

[0026] Specifically, the bottom of the mounting seat 1 is fixedly connected with a support base 23. Bolts are equidistantly rotatably connected inside the support base 23. The outside of the clamping plate 5 is of an arc-shaped structure, and an anti-slip pad is fixedly connected to the inner side of the clamping plate 5. A slot matching with the first lead screw 11 is opened at the bottom of the insertion block 7, and limiting slots matching with the limiting rod 13 are opened on both sides of the bottom of the insertion block 7 and located on both sides of the slot.

[0027] Through the above technical solution, the clamping plate 5 designed with an arc structure and the anti-slip pad inside it can better fit the surface of the cylindrical rod 6, further improving the stability.

[0028] During use, first install the support base 23 to the corresponding working position through multiple bolts. When it is necessary to install and fix the lightning rod, first insert the rod 6 into the inside of the fixing groove 2 through the insertion block 7 at the bottom. During the insertion process, the inclined surface at the top of the clamping block 3 can be pushed by the bottom of the insertion block 7, pushing the clamping blocks 3 on both sides into the inside of the mounting seat 1. At the same time, the first spring 10 is compressed by the clamping block 3 until the insertion block 7 is completely inserted into the inside of the mounting seat 1. The clamping block 3 can then bounce into the corresponding card slot 8 under the rebounding force of the first spring 10, completing the fixation of the rod 6. And while the insertion block 7 descends, it can push the threaded block 12 to slide downward under the limitation of the limiting rod 13. The threaded block 12 then drives the first lead screw 11 and the first bevel gear 15 to rotate through the threaded connection relationship, so that the first bevel gear 15 drives the second bevel gears 17 on both sides and the corresponding rotating shafts 16 to rotate through the meshing relationship. The rotating shaft 16 then drives the first pulley 18 on the other side to rotate, so that the first pulley 18 drives the corresponding second pulley 20 and the threaded ring 22 to rotate through the transmission belt 21. The threaded ring 22 then drives the second lead screw 19 and the corresponding clamping plate 5 to slide inside the fixing frame 4 through the threaded connection relationship, making the clamping plates 5 on both sides move closer to each other until the two sides of the rod 6 are clamped and fixed, thus realizing the vertical reinforcement of the rod 6, effectively avoiding the rod 6 tilting and shaking due to bad weather, which affects the stability and reduces the service life. This device can install and fix the lightning rod through the set support base 23 and the mounting seat 1, increasing the contact area with the ground, thus effectively improving the use stability. And while installing and fixing the lightning rod, it can drive the clamping plates 5 on both sides above the mounting seat 1 to vertically fix the lightning rod, effectively avoiding the rod 6 being difficult to support strong winds and tilting and shaking during bad weather, thus improving the service life of the rod 6. By pulling the pull rod 9, the corresponding clamping block 3 can be driven to slide outside the card slot 8, and the rod 6 can be removed through the reverse process operation of the above principle, effectively improving the disassembly and assembly efficiency. The clamping plate 5 designed with an arc structure and the anti-slip pad inside it can better fit the surface of the cylindrical rod 6, further improving the stability.
