[0007] To achieve the above objectives, the present invention provides the following technical solution: a foldable photovoltaic bracket, including a fixed base, wherein an inverted trapezoidal rotating groove is provided at the top of the fixed base, and a folding component is rotatably disposed inside the inverted trapezoidal rotating groove;

[0008] The folding assembly has a support plate. A first guide groove is provided at the top of one side of the plate. A limiting shaft is slidably provided inside the first guide groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model features a folding assembly at the top of a fixed base, which pulls apart two placement plates. During movement, the placement plates cause a second rotating plate and a limiting rotating plate to rotate, forming two triangular structures. This enhances the stability of the folding assembly. The limiting rotating plate rotates, and its other end engages with a limiting through-hole inside the second guide groove, securing it with a limiting pin. This facilitates adjustment of the photovoltaic panel's angle during installation. After the limiting rotating plate is fixed, it forms a triangular structure with the placement plates and the fixed base, further stabilizing the photovoltaic panel installation. The folding assembly allows for quick installation of the bracket and is easy to store and carry, saving workers significant time and effort.

[0018] 2. This utility model features a convex groove at the top of the placement plate, allowing the mounting component to slide within the groove. This adjustment is made to accommodate different photovoltaic panel sizes. By tightening the first hexagonal socket bolt, the fixing bracket slides on the upper outer side of the first sliding block, pressing and fixing the fixing bracket to the edge of the photovoltaic panel. By tightening the second hexagonal socket bolt, the teeth of the second sliding block engage with the grooves of the first sliding block, thus fixing the installation position of the first sliding block and preventing it from shifting during installation, which would hinder the rapid installation of the photovoltaic panel.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5 As shown, this utility model provides a foldable photovoltaic bracket, including a fixed base 1, with an inverted trapezoidal rotating groove at the top of the fixed base 1, and a folding component 2 rotatably disposed inside the inverted trapezoidal rotating groove;

[0030] The folding assembly 2 has a support plate 21 for supporting the photovoltaic panel. A first guide groove 22 is formed at the top of one side of the plate 21. A limiting shaft 23 is slidably mounted inside the first guide groove 22. When the first rotating plate 24 rotates, it drives the limiting shaft 23 to slide inside the first guide groove 22. The bottom end of the limiting shaft 23 is fixedly mounted on the first rotating plate 24, and one end of the first rotating plate 24 is in contact with the bottom end of the plate 21. A second rotating plate 25 is rotatably mounted at the bottom middle part of the first rotating plate 24, and one end of the second rotating plate 25 is in contact with the plate 21. The other side bottom end is rotatably connected, and the first rotating plate 24 and the second rotating plate 25 rotate to form a triangle with the placement plate 21, thereby increasing the stability of the placement plate 21. The middle inner wall of the placement plate 21 is provided with a limiting rotating plate 26, and the limiting rotating plate 26 is an L-shaped plate. When the limiting rotating plate 26 rotates, the other end of the limiting rotating plate 26 rotates with the outside of the limiting pin inside the limiting through hole 5, thereby limiting the limiting rotating plate 26. After being fixed, the limiting rotating plate 26 forms a triangle with the placement plate 21 and the fixed base 1, thereby increasing the stability of the placement plate 21 installation.

[0031] Specifically, a convex groove is provided at the top of the placement plate 21, and the mounting component 3 is slidably installed inside the convex groove;

[0032] The mounting assembly 3 has a first sliding block 31 as a support. The first sliding block 31 slides inside a convex groove at the top of the placement plate 21. The first sliding block 31 is a convex block. A fixing frame 32 is slidably provided on the upper outer side of the first sliding block 31. A first internal hex bolt 33 is spirally rotated in the middle of the fixing frame 32. A threaded groove is provided at the center of the top of the first sliding block 31. The other end of the first internal hex bolt 33 is threadedly connected to the threaded groove of the first sliding block 31. The first internal hex bolt 33 tightens and abuts and fixes the fixing frame 32 against the edge of the photovoltaic panel, thereby adapting to photovoltaic panels of different sizes. A toothed groove is provided on the lower outer side of the first sliding block 31. The toothed groove engages with the retaining teeth on the outer side of the second sliding block 35, thereby achieving the purpose of fixing the first sliding block 31.

[0033] Furthermore, a second guide groove 4 is provided on the top surface of the fixed base 1, and limit through holes 5 are provided at equal intervals on both sides of the second guide groove 4. Limit pins are inserted and connected inside the limit through holes 5, and the outer side of the limit pins is rotatably connected to the other end of the limit rotating plate 26. After the limit rotating plate 26 is fixed by the fixing pin, it forms a triangle with the placement plate 21 and the fixed base 1, which increases the support stability of the photovoltaic bracket.

[0034] Furthermore, a support frame 6 is fixedly provided on the top of the other side of the placement plate 21. The support frame 6 is an L-shaped plate, which fits the bottom of the photovoltaic panel with the inner wall of the support frame 6. An adjustment knob 7 is threaded through the upper part of the support frame 6. A limiting plate 8 is provided at the lower part of the adjustment knob 7. The outer side of the limiting plate 8 fits with the inner wall of the support frame 6. When the adjustment knob 7 is rotated, it causes the limiting plate 8 to move downward. The limiting plate 8 fits with the lower edge of the photovoltaic panel, thereby fixing the bottom of the photovoltaic panel during use.

[0035] It is worth noting that a spring 34 is sleeved on the outside of the first internal hex bolt 33, and the bottom end of the spring 34 abuts against the top end of the first sliding block 31, and the spring 34 undergoes elastic deformation to stretch and contract.

[0036] It is worth noting that a convex groove is provided on the outer side of the placement plate 21, and a second sliding block 35 is slidably provided inside the convex groove. The second sliding block 35 is a convex block, which makes sliding inside the convex groove more stable. The outer side of the second sliding block 35 is provided with locking teeth, which engage with the groove on the outer side of the first sliding block 31.

[0037] It is worth mentioning that a second hexagonal socket bolt 36 is threadedly mounted at the outer center of the second sliding block 35, and the second hexagonal socket bolt 36 passes through the second rotating plate 25 and is threadedly connected to the lower part of the first sliding block 31. The rotation of the second hexagonal socket bolt 36 causes the second sliding block 35 to engage with the first sliding block 31, thereby preventing the first sliding block 31 from moving during use.

[0038] Working Principle: During use, the operator first unfolds the folding component 2 to match the installation dimensions of the photovoltaic panel. The fixing base 1 is then installed and fixed using bolts. As the folding component 2 is unfolded, the first rotating plate 24 and the second rotating plate 25 rotate. The limiting shaft 23 on one side of the top of the first rotating plate 24 and the second rotating plate 25 slides inside the first guide groove 22, causing the limiting rotating plate 26 to rotate and open. The other end of the limiting rotating plate 26 is then aligned with the limiting through hole 5 inside the second guide groove 4 and fixed using a limiting pin. After the limiting rotating plate 26 is fixed, it forms a triangular structure with the placement plate 21 and the fixing base 1, making the placement plate 21 more stable during photovoltaic panel installation. This allows for quick installation and storage of the photovoltaic bracket, saving operators significant time and effort and improving work efficiency. During photovoltaic panel installation, the first sliding block 31 in the sliding mounting assembly 3 is moved to the fixed position of the photovoltaic panel by sliding mounting assembly 3. The first hexagon socket bolt 33 is tightened. The first hexagon socket bolt 33 rotates spirally, causing the fixing frame 32 to slide on the upper outer side of the first sliding block 31, pressing the fixing frame 32 against the edge of the photovoltaic panel. The spring 34 undergoes elastic deformation to stretch and contract. After the fixing frame 32 is tightened, the second hexagon socket bolt 36 is tightened. The second hexagon socket bolt 36 rotates spirally inside the second sliding block 35, engaging the retaining teeth on the outer side of the second sliding block 35 with the retaining groove on the outer side of the first sliding block 31, thereby fixing and limiting the first sliding block 31. The bottom end of the photovoltaic panel is then brought into contact with the inner wall of the support frame 6. The adjustment knob 7 is rotated, causing the limiting plate 8 to move downward and fit against the top end of the photovoltaic panel, thereby fixing the bottom end of the photovoltaic panel.
