At this time, the volume of the bracket is reduced, which is convenient for carrying the bracket. After the bracket is carried to the site, the bracket can be opened and the photovoltaic panel can be installed. There is no need to assemble the bracket, which is convenient for the staff to install the photovoltaic panel.

[0024] In the present invention, the locking assembly includes a notch 19, which is provided on one side of the fixed plate 10 and passes through the fixed plate 10. Two slides 17 are slidably connected in the notch 19, and a clamping block 15 is welded on one side adjacent to the two slides 17. Both ends of the rotating shaft 14 pass through the connecting plate to provide a square groove 16, and the clamping block 15 is clamped with the square groove 16. An elastic component is provided in the notch 19 to reset the slide 17 after it moves. The elastic component is a spring 18, which is provided in the notch 19 and is located between the two slides 17. Both ends of the spring 18 are fixed to the two slides 17 respectively. When the two slides 17 are pulled to move in opposite directions in the notch 19, the two slides 17 will drive the clamping block 15 to move and stretch the spring 18, so that the clamping block 15 is disengaged from the square groove 16 on the rotating shaft 14. At this time, the support rod 11 can be rotated. When the support rod 11 is rotated to fit with the second support plate 8 After that, release the slide 17, at this time the spring 18 will pull the two slides 17 to move in opposite directions, so that the block 15 is inserted into the square groove 16 on the rotating shaft 14, thereby fixing the support rod 11, and both sides of the support rod 11 are welded with a pressure block 12 for pressing the second support plate 8, and the pressure block 12 will also assist in pressing the first support plate 2 and the second support plate 8. Two heightening blocks 6 for limiting the first support plate 2 are welded on the upper surface of the bottom plate 3. When the first support plate 2 is in contact with the bottom plate 3, the heightening block 6 will limit the first support plate 2. A handle 9 is fixed on one side of the fixing plate 10 by bolts. When the bracket is folded, the bracket can be picked up by the handle 9. A plurality of self-locking universal wheels 5 are fixed at the bottom of the bottom plate 3 by bolts, and the self-locking universal wheels 5 are evenly distributed. After the photovoltaic panel is installed, the staff can push the bracket to move by the self-locking universal wheels 5 to adjust the position of the bracket.

[0025] Working principle: when in use, first lift the second support plate 8 upwards, the second support plate 8 will drive the first support plate 2 to rotate upwards through the L-shaped plate 7, so that the support rod 11 is disengaged from the groove 13 on the second support plate 8, and then push the second support plate 8 to move downward along the slide groove 4 on the first support plate 2 through the L-shaped plate 7. When the L-shaped plate 7 moves to the bottom of the slide groove 4, rotate the second support plate 8 to make the second support plate 8 fit with the first support plate 2, and then rotate the first support plate 2 downward to make the first support plate 2 fit with the bottom plate 3. At this time, the heightening block 6 will limit the first support plate 2, and then pull the two slides 17 to move in opposite directions in the notch 19. The two slides 17 will drive the block 15 to move and stretch the spring 18, so that the block 15 and the rotating The square groove 16 on the shaft 14 is disengaged, and the support rod 11 can be rotated at this time. After the support rod 11 is rotated to fit the second support plate 8, the slide 17 is released. At this time, the spring 18 will pull the two slides 17 to move in opposite directions, so that the block 15 is inserted into the square groove 16 on the rotating shaft 14, thereby fixing the support rod 11, so that the support rod 11 presses the second support plate 8 and the first support plate 2, and the pressing block 12 will also assist in pressing the first support plate 2 and the second support plate 8, thereby completing the folding of the bracket, reducing the volume of the bracket at this time, making it convenient to carry the bracket. After the bracket is carried to the site, the bracket can be opened and the photovoltaic panel can be installed without assembling the bracket, which is convenient for the staff to install the photovoltaic panel.
