[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0028] Please see Figure 1-2In this embodiment of the utility model, a balcony photovoltaic bracket includes vertical rods 2, horizontal rods 3, a telescopic mechanism, a fixed base 6, and hooks 7. Vertical rods 2 are installed at both ends of the horizontal rods 3. Hooks 7 are installed at the top of each of the two vertical rods 2, and fixed bases 6 are rotatably installed at the top of each of the two vertical rods 2. Telescopic mechanisms are rotatably installed at the bottom of each of the two vertical rods 2, with a fixed base 6 rotatably installed at the end of the telescopic mechanism away from the vertical rod 2. The telescopic mechanism includes a splicing rod I 4, a splicing rod II 5, and a spring telescopic assembly 8. One end of the splicing rod I 4 is inserted into the splicing rod II 5 and connected by the spring telescopic assembly 8. The vertical rods 2 have a U-shaped cross-section, and the internal spacing of the vertical rods 2 is greater than the width of the splicing rod I 4. The photovoltaic module 1 is installed on the fixed base 6 by bolts 10, and the fixed base 6 is then fixed to the vertical rods 2 and splicing rod II 5 respectively by pins 9. One end of the splicing rod I 4 is connected to the splicing rod II 5 by the spring telescopic assembly 8, and the other end of the splicing rod I 4 is fixed to the bolt hole of the vertical rod 2 by bolts 10. Hooks 7 are installed above vertical rod 2, and horizontal rods 3 are installed below. When in use, the user hangs the photovoltaic bracket system on the balcony railing using the hooks and secures it with bolts. The horizontal beam 3 is connected to the balcony railing below the photovoltaic bracket system using stainless steel cable ties. Vertical rod 2 has a U-shaped cross-section, and the internal spacing must be greater than the width of splicing rod 4.

[0029] like Figure 5-10The structure of the splicing rod 4 is square tube-shaped, with a centrally located column 403 inside. The column 403 has a notch at the spring telescopic assembly 8. One end of the splicing rod 4 is cut at an angle, and a first connecting hole 401 is opened on the side wall of the angled end for connection with the vertical rod 2. A limiting hole 402 is opened on the top surface of the splicing rod 4. The structure of the splicing rod 5 is square tube-shaped, with a hollow interior. One end of the splicing rod 5 is cut at an angle, and a second connecting hole 501 is opened on the side wall of the angled end. An angle adjustment hole 502 is opened on the top surface of the splicing rod 5. The spring telescopic assembly 8 is located in the limiting hole 402 of the splicing rod 4. The spring telescopic assembly 8 includes a base 801, a spring 802, a stop post 803, and a sleeve 804. The bottom end of the spring 802 is fitted onto the outer side of the upper protrusion of the base 801, and the top end of the spring 802 is fitted onto the outer side of the lower protrusion of the stop post 803. The sleeve 804 is fitted onto the outer side of the stop post 803. After the components of the spring telescopic assembly 8 are assembled, the outer periphery of the base 801 and the sleeve 804 is coated with structural adhesive 11. The radius r of the hemisphere at the end of the stop post 803 is greater than the splicing gap d between splicing rod I 4 and splicing rod II 5. The structure of splicing rod I 4 and splicing rod II 5 is similar to a square tube. One end of splicing rod I 4 is cut at an angle, and a first connecting hole 401 is opened on the side wall at the angled end for bolt 10 to connect the telescopic mechanism 8 and the vertical rod 2. A vertical post 403 is set in the middle of the square tube, and a limiting hole 402 is machined downward from the top surface of splicing rod I to ensure that the center of the circular hole is in the middle of the top surface of the rod. The interior of splicing rod II 5 is hollow. One end of splicing rod II 5 is cut at an angle, and a second connecting hole 501 is opened on the side wall at the angled end. Angle adjustment holes 502 with different spacing are opened on the top of the square tube to ensure that the angle adjustment holes 502 are located in the center of the top surface of the rod. These angle adjustment holes 502 achieve angle adjustment by cooperating with the limiting hole 402. Splicing rod I 4 and splicing rod II 5 are connected by a spring telescopic assembly 8. The spring telescopic assembly 8 includes a base 801, a spring 802, a stop post 803, and a sleeve 804. The spring 802 is fitted around the protruding platform of the base 801 and the stop post 803, and the sleeve 804 is fitted around the stop post 803. These components are pre-assembled and placed in the limiting hole 402. In the natural state, the distance by which the stop post 803 protrudes from the outer surface of splicing rod II 5 should be greater than the radius r of its end hemisphere. There is a splicing gap d between splicing rod I 4 and splicing rod II 5, which is the distance between the outer surface of splicing rod I 4 and the outer surface of splicing rod II 5. The radius r of the hemisphere at the end of the stop post 803 must be greater than d. When angle adjustment is needed, the stop post 803 is pressed downwards until the hemisphere at the end of the stop post 803 is flush with the outer surface of splicing rod II 5. Because the radius r of the end hemisphere is greater than the splicing gap d, the inner surface of splicing rod II 5 still intersects with the hemisphere at the end of the stop post 803.Therefore, splicing rod II 5 slides along the length of splicing rod I 4. When it encounters the hemispherical end of the stop post 803, the inner surface of splicing rod II 5 presses against the hemispherical end of the stop post 803, causing the stop post 803 to compress the spring downwards. When the top of the stop post 803 is lower than the inner surface of splicing rod II 5, splicing rod II 5 can slide. When it encounters the angle adjustment hole 502 on splicing rod II 5, the stop post 803 extends under the elastic force of the spring 802, preventing splicing rod II 5 from sliding further, thus completing the angle adjustment. It should be noted that, in order to prevent the spring telescopic assembly 8 from coming off during use, structural adhesive 11 is applied to the outer periphery of the sleeve 804 and the base 801 respectively. After it cures, the spring telescopic assembly 8 is fixed to the inner wall of the limiting hole 402, ensuring that the sleeve does not extend beyond the outer surface of splicing rod I 4. In this way, the spring telescopic assembly 8 is completely confined within the limiting hole 402, and the stop post 803 is also prevented from coming off under the fixation of the sleeve 804. Figure 11 As shown, the balcony photovoltaic support system is highly pre-assembled, facilitating packaging and transportation. After receiving the product, users need to install the crossbar 3 and hook 7 themselves, then unfold the support system and adjust the angle for use.

[0030] like Figure 3-4 As shown, the mounting base 6 includes a top plate 601, a vertical plate 602, a side plate 604, and a flat plate 606. Side plates 604 are provided on both sides of the flat plate 606, and each side plate 604 has a third connecting hole 605. A vertical plate 602 is provided at the top of the flat plate 606, and a top plate 601 is provided at the top of the vertical plate 602. The flat plate 606 has a mounting hole 607. A stiffening rib 603 is installed between the top plate 601 and the vertical plate 602. The top plate 601, vertical plate 602, side plate 604, and flat plate 606 are integrally formed. The mounting base 6 mainly includes a top plate 601, a vertical plate 602, a stiffening rib 603, a side plate 604, a third connecting hole 605, a flat plate 606, and a mounting hole 607. The photovoltaic module 1 is placed on top of the flat plate 606, and the mounting hole 607 is provided on the top of the flat plate 606 to facilitate the fixing of the photovoltaic module 1 with bolts 10. The C-shaped structure formed by the top plate 601, vertical plate 602, and flat plate 606 can wrap around the outer frame of the photovoltaic module 1, fixing the module and preventing it from sagging or shifting upwards under gravity and wind load, thus reducing the damaging effect of bolts on the photovoltaic module frame. A stiffening rib 603 is provided on one side of the vertical plate 602 to improve its support and enhance the structural strength of the mounting base 6. Side plates 604 are symmetrically arranged along the width of the flat plate 606, with a third connecting hole 605 on top for easy connection to the corresponding holes at the ends of the vertical rod 2 and splicing rod II 5. It should be noted that the spacing between the symmetrically arranged side plates is greater than the width of the splicing rod II and the vertical rod.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
