In the construction of PV systems, the PV mounting system, as a key component supporting the PV panels, is crucial for its stability and reliability. The triangular connector used in the PV mounting system, as an important component connecting the PV panels and the mounting system, is an indispensable link.

[0003] According to the authorized announcement number CN203562993U, a triangular connector for photovoltaic brackets is disclosed. It includes a column, a connecting sleeve, and a triangular fixing base. The connecting sleeve is provided with several positioning components, which are evenly arranged vertically on the connecting sleeve.

During use, it is inconvenient to adjust the photovoltaic bracket and the column at multiple angles, and the scope of use is limited.

[0005] Therefore, we propose a triangular connector for photovoltaic brackets that can solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a triangular connector for photovoltaic brackets, which solves the problems mentioned in the background art.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a triangular connector for photovoltaic brackets, including a triangular connecting frame 1 and a support rod 13. A rotating block 11 is rotatably connected to the inner side of the triangular connecting frame 1. Connecting rods 18 are symmetrically installed on both sides of the rotating block 11. The connecting rods 18 on both sides of the rotating block 11 are rotatably connected to the inner walls of both sides of the triangular connecting frame 1 through bearings. A slot 12 is opened at the outward end of the rotating block 11, and the support rod 13 is inserted into the slot 12. Two sets of mounting holes 14 are opened through the side of the triangular connecting frame 1 away from the support rod 13. The two sets of mounting holes 14 are distributed on both sides of the limiting block 2.

[0020] In this technical solution, the triangular connecting frame 1 can be fixed in the designated position of the photovoltaic bracket by passing screws through the mounting hole 14. The slot 12 at one end of the rotating block 11 facilitates the insertion of the support rod 13. The angle of use of the support rod 13 can be adjusted by the connecting rods 18 on both sides of the rotating block 11.

[0021] In this embodiment, the fixing mechanism is used to fix the triangular connecting frame 1 and the support rod 13. The fixing mechanism includes a limiting block 2, which is fixedly installed on the inner wall of the triangular connecting frame 1 on the side away from the rotating block 11. A limiting hole 21 is opened on the side of the limiting block 2 near the rotating block 11. The side of the limiting block 2 near the rotating block 11 is arc-shaped. The limiting holes 21 are evenly distributed on the outer side of the limiting block 2. A sliding groove 22 is opened on the side of the rotating block 11 away from the slot 12. A slider 23 is slidably connected inside the sliding groove 22. The middle of the slider 23 passes through and... A limiting rod 24 is fixedly installed. The end of the limiting rod 24 away from the slot 12 is inserted into the limiting hole 21 on the outside of the limiting block 2. The size of the limiting rod 24 matches that of the sliding groove 22. The end of the limiting rod 24 away from the limiting block 2 is movably connected to one end of the support rod 13. The inner walls on both sides of the slot 12 are provided with first fixing holes 15. The end of the support rod 13 that is inserted into the slot 12 is provided with a second fixing hole 16. The rotating block 11 and the support rod 13 are fixedly connected by bolts 17 through the first fixing hole 15 and the second fixing hole 16.

[0022] In this technical solution, after the use angle of the support rod 13 is adjusted, the top end of the support rod 13 is fully inserted into the slot 12, which can push the end of the limiting rod 24 placed inside the slot 12 into the slide groove 22. At the same time, the other end of the limiting rod 24 moves out of the slide groove 22 and is inserted into the corresponding limiting hole 21 on the outside of the limiting block 2, which can automatically limit the rotation block 11. Then, the bolt 17 passes through the first fixing hole 15 and the second fixing hole 16 to facilitate the fixed connection between the rotation block 11 and the support rod 13, and further improve the connection stability between the triangular connecting frame 1 and the support rod 13.

[0023] In this embodiment, a spring 25 is provided on the side of the slider 23 away from the slot 12. The spring 25 is sleeved on the outside of the limiting rod 24, and the two ends of the spring 25 are fixedly connected to the outside of the slider 23 and the inner wall of the groove 22, respectively.

[0024] In this technical solution, the spring force of the spring 25 can push the slider 23 to move in the groove 22, thereby pulling one end of the limiting rod 24 out of the limiting groove outside the limiting block 2, thereby releasing the fixed connection between the rotating block 11 and the triangular connecting frame 1, which facilitates the subsequent adjustment of the operating angle of the rotating block 11.

[0025] When using a triangular connector for a photovoltaic bracket, the triangular connector 1 can be fixed in the designated position of the photovoltaic bracket by passing a screw through the mounting hole 14. The slot 12 at one end of the rotating block 11 facilitates the insertion of the support rod 13. The operating angle of the rotating block 11 and the support rod 13 can be adjusted by the connecting rods 18 on both sides of the rotating block 11. After the operating angle of the support rod 13 is adjusted, the top end of the support rod 13 is fully inserted into the slot 12, which pushes the end of the limiting rod 24 placed inside the slot 12 into the slide groove 22. At the same time, the other end of the limiting rod 24 moves out of the slide groove 22 and inserts into the corresponding limiting position on the outside of the limiting block 2. The rotating block 11 can be automatically limited within the hole 21. Then, the first fixing hole 15 and the second fixing hole 16 are passed through the bolt 17 to facilitate the fixed connection between the rotating block 11 and the support rod 13, further improving the connection stability between the triangular connecting frame 1 and the support rod 13. When it is necessary to readjust the use angle of the support rod 13, the bolt 17 is removed to release the fixed connection between the rotating block 11 and the support rod 13. The spring force of the spring 25 can push the slider 23 to move in the slide groove 22, thereby pulling one end of the limiting rod 24 out of the limiting hole 21 on the outside of the limiting block 2. Then, the support rod 13 and the rotating block 11 can be rotated to adjust the use angle.
