[0033] In the photovoltaic panel bracket described above, the middle part of the frame of the photovoltaic panel is mounted on the support frame by bolts, providing a basic connection; the photovoltaic panels are closely arranged, and a clamping mechanism is installed at the convergence of the frame to achieve an associated connection between the photovoltaic panels, which can enhance the overall connection strength and better transmit and disperse the force of the photovoltaic panels, thereby enhancing the overall stability;

[0034] Moreover, during installation, the clamping mechanism is pushed into the intersection of the frames, and the lock tongue in the compressed state is triggered to pop out and pass through the perforations of the two connected frame walls; the installation operation is simple, the construction work is convenient, and the overall work efficiency is improved.

[0035] Furthermore, if Figures 3 to 6 As shown, the clamping mechanism 300 includes a box body 310 with an open bottom, and a plurality of support frames 320 are fixedly provided on the top surface of the box body 310.

[0036] Furthermore, if Figure 7As shown, the support frame 320 includes a first vertical plate 321 and a second vertical plate 322 arranged opposite to each other. The first vertical plate 321 and the second vertical plate 322 are connected by a third vertical plate 323. The first vertical plate 321, the second vertical plate 322, and the third vertical plate are all vertically fixed to the top surface of the box body. The connection between the second vertical plate 322 and the third vertical plate 323 is close to the center of the box body 310. The second vertical plate 322 is parallel to the third vertical plate 323 of the other support frame, thereby forming a "cross"-shaped card slot.

The locking tongue 410 includes a threaded clamping head 411 and a first guide rod 412. The diameter of the first guide rod is smaller than the diameter of the clamping head. The diameter of the first guide rod 412 is adapted to the diameter of the first through hole 324. The locking tongue 410 slides through the first through hole 324 and the second through hole 325. The first spring 420 is sleeved on the first guide rod 412 and is clamped between the clamping head 411 and the first vertical plate 321 to provide an elastic force for pushing the clamping head outward. By using the first spring as a pushing component, the compressible condition can be met, and the locking tongue can be quickly ejected when the blockage is released to achieve locking. The overall structure is simple and easy to operate.

[0038] Furthermore, if Figure 3 、 Figure 5 As shown, the blocking structure 500 includes a pressure plate 510 and a second spring 520; the pressure plate 510 is in a "cross" shape, adapted to the shape of the clip groove 330, and the pressure plate moves vertically close to the groove wall of the clip groove; the top surface of the box body 310 is provided with a recessed groove 311 at the four end positions corresponding to the clip groove, and the second spring 520 is placed in the recessed groove 311 to provide elastic support for the pressure plate 510, so that the pressure plate is at a height that blocks the lock tongue; the overall structure is simple, and a plurality of second springs are used to provide a buffer support for the pressure plate, which can not only meet the blocking limit of the lock tongue, but also facilitate the subsequent release of the blocking of the lock tongue by squeezing the pressure plate. The overall triggering method is simple, matching the action of snapping the card slot into the gathering point of the frame, and is easy to use and operate;

[0039] Furthermore, a plurality of support blocks are fixedly provided on the inner top wall of the box body. The positions of the support blocks correspond to the positions of the four ends of the clamping groove, providing space for the sinking groove to be set down, so as to provide space for inserting and placing the second spring.

[0041] Furthermore, the four ends of the pressure plate are widened to increase the contact area with the second spring to facilitate force transmission; and the bottom surface of the end is fixed with a protrusion, the diameter of the protrusion is adapted to the inner diameter of the second spring.

The bottom of the second guide rod 414 extends into the interior of the box body 310 through the second guide hole 312 and is connected to the reset structure 600 inside the box body; the reset structure is adjusted to drive multiple clamps to move synchronously, so that the lock tongue moves in the direction of compressing the first spring until the end face of the clamp is received at the inner side of the port of the second through hole, and the pressure plate is reset to the height position of blocking the lock tongue under the elastic force of the second spring, and the lock tongue is reset to the triggering position; the designed second guide rod can further limit the movement of the clamp head, and as a connecting component with the reset structure, the multiple lock tongues are reset and adjusted at the same time through the reset structure, so that the pressure plate can be smoothly moved up to the blocking position, so that the lock tongue can be compressed and energy stored, which is convenient for subsequent installation; this design enables the clamping mechanism to realize the function of recycling, or it can be adjusted and used again after accidental triggering, which is convenient for practical application.

[0043] Furthermore, if Figure 5 、 Figure 6 As shown, a support plate 340 is installed inside the box body 320. The shape of the support plate is adapted to the internal shape of the box body. The support plate is fixed to the support block by bolts.
