[0029] Such as Figures 1-6 ;

[0030] A photovoltaic busbar box bracket includes a support vertical plate 1, a cover plate 11, a support horizontal plate 12, and an internal thread block 13. The cover plate 11 is installed at the upper end of the support vertical plate 1 through a hinge. The cover plate 11 is used to cover the upper end of the support vertical plate 1 to protect the photovoltaic busbar box 24 inside the support vertical plate 1. The support horizontal plate 12 is installed inside the support vertical plate 1. The support horizontal plate 12 is used to support and install the photovoltaic busbar box 24. The internal thread block 13 is installed at the lower end of the support horizontal plate 12. A support rod can be threadedly installed on the internal thread block 13. The lower end of the support rod contacts the ground, which can assist in supporting the support horizontal plate 12 and the photovoltaic busbar box 24 to increase stability. A bracket assembly 2 is provided on the support vertical plate 1 and the support horizontal plate 12. The bracket assembly 2 facilitates the support of the photovoltaic busbar box;

[0031] The bracket assembly 2 includes a U-shaped frame one 21, a U-shaped frame two 211, and a connecting square tube 22. The U-shaped frame two 211 is fixedly installed at one end of the U-shaped frame one 21. The connecting square tube 22 is fixedly installed inside the support vertical plate 1. The U-shaped frame two 211 is inserted into the connecting square tube 22 and connected by bolts, so as to connect the support vertical plate 1 and the support horizontal plate 12 to the U-shaped frame one 21. The other end of the U-shaped frame one 21 is installed with a support plate 212 through bolts. The support plate 212 is used to support and install the threaded rod 23. A socket one 213 is evenly opened on the U-shaped frame one 21. The socket one 213 is used for installing bolts for fixation. When the U-shaped frame one 21 is vertically installed on the wall, such as Figure 5 , after the U-shaped frame two 211 adjusts its position and then is inserted into the connecting square tube 22 for connection, the threaded rod 23 is threadedly installed on the inner wall of the support plate 212. One end of the threaded rod 23 is installed with a limit plate one 231, and an insertion tube 232 is installed on the other side of the limit plate one 231. The U-shaped frame one 21 is inserted outside the bracket column, and a socket should be opened on the inner wall of the bracket column. Rotate the threaded rod 23 to adjust the position of the limit plate one 231, push the limit plate one 231 and the insertion tube 232, so that the insertion tube 232 is inserted into the socket on the inner wall of the bracket column, increasing the connection stability between the bracket column and the U-shaped frame one 21;

[0032] In addition, the embodiment of the present application further provides a busbar box installation structure having the bracket, including a photovoltaic busbar box bracket, and further including a photovoltaic busbar box 24, a socket 241, and a chute 25. Sockets 241 are installed on both sides of the bottom end of the photovoltaic busbar box 24. The photovoltaic busbar box 24 is placed on the support cross plate 12. A chute 25 is provided on the inner wall of the support cross plate 12. The chute 25 is used to guide the sliding of the second limiting plate 26 and the third limiting plate 261. The second limiting plate 26 and the third limiting plate 261 are respectively and slidably arranged in the chute 25. The second limiting plate 26 and the third limiting plate 261 are used for clamping and connecting the photovoltaic busbar box 24. The second limiting plate 26 and the third limiting plate 261 move simultaneously, and the moving directions of the second limiting plate 26 and the third limiting plate 261 are opposite. Nuts 271 are installed on the inner sides of the second limiting plate 26 and the third limiting plate 261. The nuts 271 are used to support and install the plug 27. The plug 27 is threadedly installed in the nut 271. A plurality of nuts 271 are provided, and the installation position of the plug 27 is adjustable. The plug 27 is inserted into the socket 241 to enhance the stable connection effect of the photovoltaic busbar box 24. A first screw 28 and a second screw 281 are respectively and rotatably installed between the lower ends of the support vertical plates 1. The threads of the first screw 28 and the second screw 281 are opposite. One end of the first screw 28 and the second screw 281 are connected. By rotating the handle 282, the first screw 28 and the second screw 281 are driven to rotate. The first screw 28 is threadedly connected to the second limiting plate 26. The rotation of the first screw 28 drives the second limiting plate 26 to move in a guided manner in the chute 25. The second screw 281 is threadedly connected to the third limiting plate 261. The rotation of the second screw 281 drives the third limiting plate 261 to move in a guided manner in the chute 25. The other end of the first screw 28 is connected to the handle 282, and the other end of the second screw 281 is connected to the disc 29. When the first screw 28 and the second screw 281 rotate, the disc 29 is also driven to rotate. A plurality of second jacks 291 are evenly provided on the inner wall of the disc 29. After the rotation of the first screw 28 and the second screw 281 finally ends, bolts are installed in the second jacks 291 and connected to the inner wall of the support vertical plate 1 to limit the first screw 28 and the second screw 281 and prevent the first screw 28 and the second screw 281 from loosening during placement.

[0033] The working principle of the embodiment of this application is as follows: The second U-shaped frame 211 is inserted into and bolted to the connecting square pipe 22, thereby connecting the support vertical plate 1 and the support horizontal plate 12 to the first U-shaped frame 21. The first U-shaped frame 21 is inserted outside the bracket column, and jacks need to be opened on the inner wall of the bracket column. Rotate the threaded rod 23, and the threaded rod 23 pushes the first limiting plate 231 and the insertion pipe 232, so that the insertion pipe 232 is inserted into the jack on the inner wall of the bracket column, increasing the connection stability between the bracket column and the first U-shaped frame 21, thereby installing the first U-shaped frame 21 on the bracket column. The photovoltaic busbar box 24 is placed on the upper end of the support horizontal plate 12. By rotating the handle 282, the first screw rod 28 and the second screw rod 281 are driven to rotate. The threads of the first screw rod 28 and the second screw rod 281 are opposite. When the first screw rod 28 rotates, it drives the second limiting plate 26 to move directionally in the sliding groove 25. At the same time, when the second screw rod 281 rotates, it drives the third limiting plate 261 to move directionally in the sliding groove 25. Plugs 27 are installed on the inner sides of the second limiting plate 26 and the third limiting plate 261 through nuts 271. The plugs 27 are inserted into the sockets 241, increasing the stable connection effect on the photovoltaic busbar box 24. When the first screw rod 28 and the second screw rod 281 rotate, they also drive the disc 29 to rotate. After the rotation of the first screw rod 28 and the second screw rod 281 finally ends, bolts are installed in the second jack 291 and connected to the inner wall of the support vertical plate 1 to limit the first screw rod 28 and the second screw rod 281, preventing the first screw rod 28 and the second screw rod 281 from loosening during placement. Finally, a support rod can be threadedly installed on the internal thread block 13. The lower end of the support rod contacts the ground, which can assist in supporting the support horizontal plate 12 and the photovoltaic busbar box 24, increasing stability.
