[0030] A plurality of connecting pieces 4 are arranged between the U-shaped bars 2 and the plurality of photovoltaic panels 3. Two ends of the connecting piece 4 are respectively detachably connected to the photovoltaic panel 3, and the connecting piece 4 is slidably connected to the U-shaped bar 2;

[0031] A locking mechanism is arranged between the connecting piece 4 and the U-shaped bar 2 to define the relative positions of the connecting piece 4 and the U-shaped bar 2. As Figures 1-4 shown, a fastening bracket for a photovoltaic panel 3 includes: a square tube 1, U-shaped bars 2, connecting pieces 4 and a locking mechanism. Among them, the square tube 1 is made of an alloy tube. The length and quantity of the U-shaped bars 2 are selected according to the quantity and specifications of the photovoltaic panels 3 to be placed. When arranging, at least two U-shaped bars 2 are arranged vertically. The photovoltaic panels 3 are installed between two adjacent U-shaped bars 2. When the length of the U-shaped bar 2 is long enough, a plurality of photovoltaic panels 3 are arranged between the same two U-shaped bars 2; among them, a plurality of connecting pieces 4 are installed between the U-shaped bars 2 and the plurality of photovoltaic panels 3. Two ends of the connecting piece 4 are respectively detachably connected to the photovoltaic panel 3. The connecting piece 4 slides on the U-shaped bar 2 to adjust the corresponding position. Then, the relative positions between the connecting piece 4 and the U-shaped bar 2 are fixed by the locking mechanism to install the photovoltaic panel 3 on the U-shaped bar 2. When the position needs to be adjusted, it is convenient to adjust. When it is necessary to adjust or disassemble a certain photovoltaic panel 3, only the locking mechanism at the corresponding position on the U-shaped bar 2 needs to be disassembled, and then the connecting piece 4 on the corresponding photovoltaic panel 3 can be disassembled.

[0032] In some embodiments, U-shaped bars 5 are respectively arranged at two vertical ends of the U-shaped bar 2, and the opening direction of the U-shaped bar 5 is opposite to the opening direction of the U-shaped bar 2; there are three U-shaped bars 2, and first L-shaped plates 6 are respectively arranged between the two U-shaped bars 2 near both ends of the square tube 1 and the square tube 1. One plate of the first L-shaped plate 6 abuts against the square tube 1, and the relative positions of the first L-shaped plate 6 and the U-shaped bar 2 are defined by the locking mechanism on the first L-shaped plate 6. As Figures 1-4As shown, U-shaped strips 5 are respectively arranged at the two vertical ends of the U-shaped bar 2, wherein the opening direction of the U-shaped strip 5 is opposite to the opening direction of the U-shaped bar 2; first L-shaped plates 6 are respectively arranged between the two U-shaped bars 2 near the two ends of the square tube 1 and the square tube 1. When there are multiple U-shaped bars 2, only the connecting member 4 is used to connect the two photovoltaic panels 3 on both sides of the U-shaped bar 2 between the inner U-shaped bars 2 to form a sequential connection, while the two outermost U-shaped bars 2 are connected by the first L-shaped plates 6. A pair of locking mechanisms pass through the first L-shaped plates 6 to fix the first L-shaped plates 6, the square tube 1 and the U-shaped bar 2. After the photovoltaic panels 3 are assembled, an assembly of the square tube 1, the U-shaped bar 2 and the photovoltaic panels 3 is formed to connect the square tube 1 and all the U-shaped bars 2.

[0033] In some embodiments, the connecting member 4 is in a U-shape. The connecting member 4 is sleeved on the U-shaped bar 2 and is slidably connected to the U-shaped bar 2. The two ends of the connecting member 4 are respectively connected to the photovoltaic panels 3 on both sides of the U-shaped bar 2. One end of the locking mechanism abuts against the middle of the connecting member 4, and the other end of the locking mechanism abuts against the U-shaped strip 5 to limit the relative positions of the connecting member 4 and the U-shaped bar 2. As Figures 1-4 shown, the connecting member 4 is in a U-shape. Of course, the connecting members 4 of the two outermost U-shaped bars 2 do not need to connect the two photovoltaic panels 3 and can be in a bow shape. The connecting member 4 is sleeved on the corresponding U-shaped bar 2 and is adjusted correspondingly according to the position where the photovoltaic panel 3 needs to be installed. The connecting member 4 and the photovoltaic panel 3 can be connected by bolts, and then the position of each connecting member 4 and the corresponding U-shaped bar 2 is limited by the locking mechanism to form an assembly.

[0034] In some embodiments, the locking mechanism includes: an adjusting cylinder 7, an adjusting rod 8 is arranged in the adjusting cylinder 7, an abutting portion 9 is arranged at one end of the adjusting rod 8, the adjusting rod 8 is arranged in the adjusting cylinder 7 with a gap, assembly ports 10 are respectively arranged on the opposite sides of the adjusting cylinder 7, a sliding block 11 is arranged in the assembly port 10 perpendicular to the adjusting cylinder 7, and the adjusting rod 8 is screwed to the sliding block 11; a pair of clamping grooves 12 adapted to the vertical ends of the U-shaped strip 5 are arranged at one end of the sliding block 11 close to the abutting portion 9, and the vertical ends of the U-shaped strip 5 abut in the clamping grooves 12. As Figures 1-4As shown, when the locking mechanism limits the positions of the connecting member 4 and the U-shaped strip 2, the adjusting rod 8 passes through the middle of the connecting member 4, and the adjusting rod 8 is screwed to the sliding block 11. Among them, the locking mechanism can be directly installed on the connecting member 4. By making the vertical ends of the two U-shaped strips 5 abut against the card slot 12, and then adjusting the adjusting rod 8 so that when it is screwed to the sliding block 11, the vertical ends of the two U-shaped strips 5 are kept abutting against the card slot 12, and the abutting portion 9 of the adjusting rod 8 abuts against the connecting member 4. In this way, the locking mechanism fixes the connecting member 4 and the U-shaped strip 2. When it is necessary to disassemble one of the photovoltaic panels 3, only the locking mechanism corresponding to the photovoltaic panel 3 needs to be adjusted to replace the photovoltaic panel 3.

One end of the L-shaped strip 13 is connected to the first L-shaped plate 6, and the other ends of the L-shaped strips 13 respectively extend towards the U-shaped strips 2 on both sides of the square tube 1. A second L-shaped plate 14 is further arranged on the U-shaped strip 2, and the other end of the second L-shaped plate 14 and the U-shaped strip 2 are detachably connected through the locking mechanism. As Figures 1-4 shown, the square tube 1 and the two outermost U-shaped strips 2 are also reinforced by the L-shaped strips 13. Among them, one end of the L-shaped strip 13 is bolted to the first L-shaped plate 6, and the other end of the L-shaped strip 13 is bolted to the second L-shaped plate 14.

As Figures 1-4 shown, a base 15 is further arranged below the square tube 1 to keep a certain height between the photovoltaic panel 3 and the ground. The bottom support 17 is bolted to the middle position at the bottom of the square tube 1, and the fixed support 16 is bolted to the top position of the base 15. The rotation between the bottom support 17 and the fixed support 16 can be achieved by using a screw rod to pass through the through holes between them, and adjusting the relative distance between the bottom support 17 and the fixed support 16 by screwing the screw rod and the nut. When rotation is required, loosen the nut, let the two rotate relative to each other to an appropriate angle, and then tighten them again using the screw rod and the nut.
