They are generally made of aluminum alloy, carbon steel, and stainless steel. When in use, PV brackets usually need to be installed on profiled steel sheets used in construction.

[0003] In existing photovoltaic brackets, the support legs are usually placed directly on the fixed base and installed by fixing bolts. This installation method cannot provide good protection for the bracket column. In windy weather, the large stress area of ​​the bracket can easily cause the bracket column and support legs to break. In order to address this technical problem, this application proposes a fastening device for photovoltaic brackets and profiled steel sheets. Utility Model Content

By rotating the pressure block, the limiting block one and the limiting block two move relative to each other. The threaded connection of the fixing bolt one can fasten the connecting rod one and the sleeve, ensuring that the entire structure remains stable under the action of external forces such as wind, and further improving the installation safety and service life of photovoltaic panels.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fastening device for a photovoltaic bracket and a profiled steel sheet includes a profiled steel sheet body. Fixed seats are fixedly connected to both the front and rear sides of the top of the profiled steel sheet body. Each fixed seat has a locking block on its inner wall.

Limiting components are provided at the top of each pressure block.

[0006] Furthermore, the adjustment assembly includes a sleeve fixedly connected to the top of the rear plate, a connecting rod slidably connected to the inner wall of the sleeve, and a fixing bolt 2 threadedly connected to the inner wall of the rear end of the connecting rod 2, with the outer wall of the fixing bolt 2 penetrating the rear end of the sleeve.

[0007] Furthermore, a connecting rod 1 is fixedly connected to the top of each of the front side plates, and a rotating seat 2 is rotatably connected to the top of both the connecting rod 1 and the connecting rod 2.

[0009] Furthermore, the limiting component includes a limiting block one fixedly connected to the top of the front pressure block, and a limiting block two fixedly connected to the top of the rear pressure block. A fixing bolt is threaded onto the inner wall of the limiting block one.

[0010] Furthermore, the outer wall of the first fixing bolt is threaded to the inner wall of the second limiting block, the outer wall of the first fixing bolt on the front side penetrates the first connecting rod, and the outer wall of the first fixing bolt on the rear side penetrates the sleeve.

[0011] Furthermore, the inner walls of the front pressing blocks are all located on the front side of the top of the card plate, and the inner walls of the rear pressing blocks are all located on the rear side of the top of the card plate.

Specifically, by sliding the second connecting rod 11 inside the sleeve 12, and cooperating with the rotating seat 10 installed at the top of the second connecting rod 11 and the top of the first connecting rod 7, the tilt angle of the support rod 13 can be adjusted. After adjustment, the second fixing bolt 16 is inserted into the second connecting rod 11 through the hole on the sleeve 12, and the position is limited by rotating the tool, so that the photovoltaic panel can receive sunlight at the most suitable angle after being installed inside the fixed frame 14. Through the stabilizing effect of the support block 15, the stability of the fixed frame 14 is ensured, further improving the stability of the photovoltaic panel installation.

[0018] The front and rear ends of the fixed base 2 are fixedly connected to the rotating base 4. The outer wall of the rotating base 4 is rotatably connected to the pressure block 5. The top of the pressure block 5 is provided with a limit component. The limit component includes a limit block 8 fixedly connected to the top of the front pressure block 5 and a limit block 9 fixedly connected to the top of the rear pressure block 5. The inner wall of the limit block 8 is threaded with a fixing bolt 6. The outer side of the fixing bolt 6 is threaded to the inner wall of the limit block 9. The outer wall of the front fixing bolt 6 passes through the connecting rod 7. The outer wall of the rear fixing bolt 6 passes through the sleeve 12. The inner wall of the front pressure block 5 is set on the front side of the top of the clamping plate 17. The inner wall of the rear pressure block 5 is set on the rear side of the top of the clamping plate 17. Specifically, by rotating the pressure block 5, the limiting block 8 and the limiting block 9 move relative to each other. By using the threaded connection of the fixing bolt 6, the connecting rod 7 and the sleeve 12 can be fastened, ensuring that the entire structure remains stable under the action of external forces such as wind, and further improving the installation safety and service life of the photovoltaic panel.

[0019] Working principle: In use, first, install the fixing seat 2 on the profiled steel sheet body 1. Then, insert the clamping block 3 into the fixing seat 2 and align the clamping plate 17 at the bottom of the connecting rod 7 and the sleeve 12 with the rotating seat 4 on the fixing seat 2. Rotate the pressure block 5 on the rotating seat 4 to clamp and limit the clamping plate 17, improving the stability of the bracket installed on the fixing seat 2. At the same time, the limiting block 8 and the limiting block 9 on the pressure block 5 will also be mutually attached and fixed by the fixing bolt 6, thereby clamping the connecting rod 7 and the sleeve 12 and strengthening the connection rod 7. The strength of the connection between the connecting rod 7 and the sleeve 12 and the clamping plate 17 can effectively prevent the connecting rod 7 and the sleeve 12 from breaking in strong winds. Then, by stretching the connecting rod 11, it slides inside the sleeve 12. With the help of the rotating seat 10 installed at the top of the connecting rod 11 and the top of the connecting rod 7, the tilt angle of the support rod 13 can be adjusted. After the adjustment is completed, the fixing bolt 16 is inserted into the connecting rod 11 through the hole on the sleeve 12 and limited by rotating the tool, so that the photovoltaic panel can receive sunlight at the most suitable angle after being installed inside the fixing frame 14.
