[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , a kind of adjustable solar flat roof photovoltaic installation bracket in this embodiment includes an upper frame 8, and an adjustment mechanism is installed at the bottom of the upper frame 8.

[0021] The adjustment mechanism includes a bottom frame 1 and an outer cylinder 5. Slide grooves 2 are opened on the front and rear sides of the top of the bottom frame 1. Slide blocks 12 are slidably connected inside the slide grooves 2. A cavity is opened inside the slide blocks 12. A pressure plate 14 is slidably connected inside the cavity. A limit rod 16 is fixedly connected inside the pressure plate 14. A second spring 15 is sleeved outside the limit rod 16. The second spring 15 is located inside the cavity. Activity grooves 7 are opened on the inner side walls of the front and rear sides of the bottom frame 1. The opposite ends of the two limit rods 16 penetrate through the slide blocks 12 and are slidably connected inside the activity grooves 7. Pull rods 3 are fixedly connected to the opposite sides of the two limit rods 16. Slide plates 4 are fixedly connected to the opposite sides of the two pull rods 3. The slide plates 4 are slidably connected inside the outer cylinder 5. A first spring 6 is installed between the two slide plates 4. A plurality of limit holes 13 are opened on the front and rear side walls of the bottom frame 1. The end of the limit rod 16 away from the pull rod 3 is inserted into the limit holes 13. The activity grooves 7 communicate with the slide grooves 2. The limit rod 16 is a cylindrical rod.

[0022] It should be noted that after moving the slide block 12 to the innermost side, the support rod 9 will rotate and lie flat on the top of the bottom frame 1. After releasing the hand, the pressure plate 14 can be inserted into the corresponding limit hole 13 by the resilience of the second spring 15 to be limited, and then the upper frame 8 and the bottom frame 1 can be stacked together, thereby reducing the occupied area and facilitating transportation.

[0023] In this embodiment, a plurality of limiting holes 13 are equidistantly distributed left and right. The limiting holes 13 communicate with the sliding groove 2. The second spring 15 is fixed to the side of the pressing plate 14 close to the pull rod 3. The bottom frame 1 is of a rectangular frame structure.

[0024] It should be noted that by providing a plurality of limiting holes 13, the angle of the upper frame 8 can be conveniently adjusted by adjusting the position of the slider 12 inside the sliding groove 2. At the same time, the limiting holes 13 can drain the rainwater flowing into the sliding groove 2 to prevent the rainwater from accumulating inside.

[0025] The top of the slider 12 is fixedly connected with a second U-shaped frame 11. The top of the second U-shaped frame 11 is hinged with a support rod 9. One end of the support rod 9 away from the second U-shaped frame 11 is fixedly connected with a first U-shaped frame 10. The first U-shaped frame 10 is hinged to the bottom of the upper frame 8. One side bottom of the upper frame 8 away from the support rod 9 is hinged to the bottom frame 1. The slider 12 is of an inverted "T" shape. Annular plates are fixedly arranged on the outer part of the pull rod 3. The outer cylinder 5 is located between the two annular plates.

[0026] It should be noted that by providing two annular plates, it is convenient to place the hands on both sides of the two annular plates and pull the two pull rods 3 to move relatively, so that the limiting rod 16 can be pulled out of the limiting hole 13.

[0027] In this embodiment, mounting plates are fixedly arranged at the four corners outside the bottom frame 1, and mounting holes are formed inside the mounting plates.

[0028] It can be understood that through the arrangement of the mounting plates and the mounting holes, the bottom frame 1 is fixed at the position where it needs to be installed.

[0029] The working principle of the above embodiment is as follows: When in use, by pulling the two pull rods 3 to move relatively, the sliding plate 4 slides in the outer cylinder 5 and squeezes the first spring 6 to make it expand and contract. At the same time, the limiting rod 16 is driven to be pulled out of the limiting hole 13 and the pressing plate 14 is driven to squeeze the second spring 15 to make it expand and contract. After being pulled out, the slider 12 can be pushed to slide. After moving the slider 12 to the innermost side, the support rod 9 will rotate and lie flat on the top of the bottom frame 1. After releasing the hand, the pressing plate 14 can be inserted into the corresponding limiting hole 13 by the resilience of the second spring 15 to be limited, and then the upper frame 8 and the bottom frame 1 can be stacked together, thereby reducing the occupied area and facilitating transportation.
