The self-locking flange 12 is fixedly connected to the U-shaped plate 11. An integral structure is formed between the self-locking flange 12 and the U-shaped plate 11, and a space is formed inside the U-shaped plate 11 and the self-locking flange 12. This space is sleeved on the purlin 2. Among them, the distance between the lower section of the self-locking flange 12 and the bottom of the purlin 2 is slightly higher than the height of the purlin 2, so that a certain distance is formed between the self-locking flange 12 and the top of the purlin 2 to provide an installation space. The bottom of the U-shaped plate 11 is provided with a positioning threaded hole 16. The U-shaped plate 11 and the purlin 2 are installed and connected through a positioning bolt 17.

At the same time, by screwing the thread of the positioning bolt 17, the positioning bolt 17 is threadedly engaged with the bottom of the U-shaped plate 11. At the same time, its top abuts against the bottom of the purlin 2. The rotation of the positioning bolt 17 can adjust the distance between the purlin 2 and the U-shaped plate 11 to be closer or farther away from each other, and further control the distance between the bottom of the self-locking flange 12 and the top of the purlin 2.

[0028] The photovoltaic module frame 3 is clamped between the self-locking flange 12 and the purlin 2 and is locked through the positioning bolt 17 to realize the self-locking of the photovoltaic module frame 3 on the purlin 2 through the locking member 1.

[0029] Please refer to Figures 2 - 5As shown, a limit threaded hole 13 is provided on the U-shaped plate 11, a limit bolt 14 is arranged in the limit threaded hole 13, the limit bolt 14 is in threaded connection with the limit threaded hole 13, a positioning hole 15 is provided on the purlin 2, one end of the limit bolt 14 is rotatably connected with the positioning hole 15. After the purlin 2 and the bottom of the U-shaped plate 11 are locked, by installing the limit bolt 14 in the limit threaded hole 13 opened on the self-locking flange 12 and making the limit bolt 14 be in threaded fit with the limit threaded hole 13, at the same time, the bottom of the limit bolt 14 is rotatably connected in the positioning hole 15 opened at the top of the purlin 2, so as to limit the lateral movement between the purlin 2 and the U-shaped plate 11 and improve the locking stability between the purlin 2 and the U-shaped plate 11.

[0030] Please refer to Figure 2 、 5 As shown, the diameter of the limit bolt 14 is smaller than the diameter of the positioning hole 15, so that the lower part of the limit bolt 14 can be rotatably connected in the positioning hole 15 to realize the lateral sliding lock between the purlin 2 and the U-shaped plate 11.

[0031] Please refer to Figure 2 、 5 As shown, a plurality of positioning holes 15 are provided, and the plurality of positioning holes 15 are equidistantly distributed along the length direction of the purlin 2. By arranging a plurality of positioning holes 15 on the upper end face of the purlin 2, the locking member 1 can be installed and locked at different positions along the length of the purlin 2. By rotatably connecting the limit bolt 14 with one of the positioning holes 15, the installation and locking of the locking member 1 on the purlin 2 are realized.

[0032] Please refer to Figures 3 - 5 As shown, the positioning threaded hole 16 is located on the side of the U-shaped plate 11 away from the self-locking flange 12, a positioning bolt 17 is arranged in the positioning threaded hole 16, the positioning bolt 17 is in threaded connection with the positioning threaded hole 16, and one end of it abuts against the bottom of the U-shaped plate 11. By using the threaded fit between the positioning bolt 17 and the positioning threaded hole 16, one end of the positioning bolt 17 abuts against the bottom of the purlin 2. By rotating and locking the positioning bolt 17, the position adjustment between the bottom of the U-shaped plate 11 and the bottom of the purlin 2 is realized, and further the locking between the locking member 1 and the purlin 2 is realized. At the same time, since the photovoltaic module frame 3 is clamped between the bottom of the self-locking flange 12 and the upper end face of the purlin 2, when the locking between the locking members 1 is carried out, the installation and limitation of the photovoltaic module frame 3 on the purlin 2 are realized.

[0033] Please refer to Figure 5As shown, the frame 3 of the photovoltaic module is in an L shape, and a groove 31 is formed on the frame 3 of the photovoltaic module; a convex tooth 21 is provided on the self-locking flange 12, and the convex tooth 21 is fixedly connected to the self-locking flange 12. The convex tooth 21 is adapted to the groove 31. By limiting between the convex tooth 21 and the groove 31, the stability of the frame 3 of the photovoltaic module locked on the purlin 2 is improved, and the frame 3 of the photovoltaic module is prevented from freely sliding along the length direction of the purlin 2.

[0034] The working principle of the present utility model:

[0035] The purlin 2 serves as a locking platform for the locking member 1 and the frame 3 of the photovoltaic module, and the purlin 2 realizes the locking of the frame 3 of the photovoltaic module on the purlin 2;

[0036] Among them, the U-shaped plate 11 and the purlin 2 enclose an integral structure. By sleeving the U-shaped plate 11 on the purlin 2, the U-shaped plate 11 can freely slide along the length direction of the purlin 2. After the U-shaped plate 11 is sleeved on the purlin 2, a distance is formed between the bottom of the self-locking flange 12 and the top of the purlin 2, providing an installation space for the clamping installation of the frame 3 of the photovoltaic module. The frame 3 of the photovoltaic module is clamped between the bottom of the purlin 2 and the top of the purlin 2. By screwing the positioning bolt 17 into the positioning threaded hole 16, while the positioning bolt 17 is in threaded cooperation with the positioning threaded hole 16, the top of the positioning bolt 17 abuts against the bottom of the purlin 2. By screwing the positioning bolt 17, the distance difference formed between the top of the purlin 2 and the bottom of the self-locking flange 12 is reduced, thereby realizing the locking of the frame 3 of the photovoltaic module located within this distance;

[0037] When the frame 3 of the photovoltaic module is installed with the self-locking flange 12, by engaging the convex tooth 21 with the groove 31 in a snap-fit manner, the lateral sliding of the frame 3 of the photovoltaic module on the self-locking flange 12 is restricted, and the stability of the locking between the self-locking flange 12 and the frame 3 of the photovoltaic module is improved;

[0038] When the locking member 1 is locked on the purlin 2, the positioning threaded hole 16 serves as the bottom limit. Among them, by threadedly connecting the limit bolt 14 with the limit threaded hole 13 and rotatably connecting the lower end of the limit bolt 14 in one of the alignment holes 15, the further locking between the locking member 1 and the U-shaped plate 11 is realized, and the stability of the locking between the two is improved.
