Technical Field
[0001] This utility model relates to the field of photovoltaic combiner box technology, specifically to a wall-mounted photovoltaic combiner box mounting bracket. Background Technology
[0002] A photovoltaic combiner box is a wiring device in a photovoltaic power generation system that ensures the orderly connection of photovoltaic modules and the function of current collection. It means that users can connect a certain number of photovoltaic cells of the same specifications in series to form photovoltaic strings, and then connect several photovoltaic strings in parallel to the photovoltaic combiner box. After current collection in the combiner box, it is used in conjunction with a controller, DC distribution cabinet, photovoltaic inverter, and AC distribution cabinet to form a complete photovoltaic power generation system and achieve grid connection.
[0003] Existing wall-mounted photovoltaic combiner boxes are usually installed on the wall surface. They are fixed by drilling holes in the wall surface and using bolts or expansion screws, which makes installation and disassembly inconvenient. Furthermore, since the dimensions of different photovoltaic combiner boxes vary, it is necessary to repeatedly drill holes in the wall surface to adapt them when replacing different models. This not only makes the installation process cumbersome but also causes significant damage to the wall surface.
[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

The top and bottom of both side walls of the combiner box body are provided with fixing seats. Each fixing seat has a through groove, and a locking sleeve is rotatably mounted within each through groove. The mounting bracket includes a mounting plate. The top and bottom of the mounting plate are evenly distributed with several screw holes. Adjusting plates are slidably mounted on both sides of the mounting plate. A lead screw is rotatably mounted on the front of the adjusting plate. Two fixing blocks are screwed onto the lead screw. One side of each fixing block has a screw that cooperates with the locking sleeve, and the screw is screwed into the locking sleeve.
[0008] Preferably, the top and bottom of the adjusting plate are provided with fixing plates, and the surface of the fixing plates is provided with through holes.

[0014] Beneficial effects
[0015] The wall-mounted photovoltaic combiner box mounting bracket provided in this embodiment of the utility model has at least one of the following technical effects:
[0016] This utility model, through the above-described technical solution, allows for easy installation and removal of the photovoltaic combiner box. First, the mounting plate is bolted to the wall, requiring only one installation without repeated disassembly. Then, the combiner box body is placed on top of the support plate. The position of the adjusting block is adjusted by rotating the screw, aligning it with the fixing seat. Next, the adjusting plates on both sides are moved towards the combiner box body, allowing the screw to insert into the fixing seat and contact the locking sleeve. Rotating the locking sleeve locks the screw and locking sleeve together. Finally, bolts are passed through the through holes and screwed into the screw holes to secure the adjusting plates, thus completing the installation and fixation of the combiner box body. This utility model simplifies the installation and disassembly of photovoltaic combiner boxes, is compatible with different models of photovoltaic combiner boxes, and eliminates the need for repeated drilling into the wall surface when installing different models, preventing significant damage to the wall surface.

[0026] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.
[0027] like Figure 1-4 The diagram shown is a structural schematic of a wall-mounted photovoltaic combiner box mounting bracket according to a preferred embodiment of the present invention.
[0028] In this embodiment, the device includes a mounting frame 1 and a combiner box body 2 mounted on the mounting frame 1. The basic functions of the combiner box body 2 are the same as those of common models on the market. The top and bottom of both side walls of the combiner box body 2 are provided with fixing seats 3. Each fixing seat 3 has a through groove 4. A locking sleeve 5 is rotatably installed in each through groove 4. The locking sleeve 5 is a hollow cylindrical structure with internal threads. The outer side wall of the fixing seat 3 has through holes for communicating with the outside. The mounting frame 1 includes a mounting plate 6. Several screw holes 7 are evenly distributed on the top and bottom of the mounting plate 6. Adjusting plates 8 are slidably installed on both sides of the mounting plate 6. The two adjusting plates 8 are symmetrically arranged. A lead screw 9 is rotatably installed at the front of the adjusting plate 8. The lead screw 9 is vertically arranged. Two fixing blocks 10 are screwed onto the lead screw 9. A screw 11 is provided on one side of the fixing block 10 to cooperate with the locking sleeve 5. The screw 11 is screwed to the locking sleeve 5. In use, first, fix the mounting plate 6 to the wall with bolts. The mounting plate 6 only needs to be installed once and does not need to be disassembled repeatedly. Then, place the combiner box body 2 on top of the support plate 17. Rotate the screw 9 to adjust the position of the fixing block 10 so that the position of the fixing block 10 is opposite to the position of the fixing seat 3. Then, move the adjusting plates 8 on both sides toward the combiner box body 2 so that the screw is inserted into the fixing seat 3 and contacts the locking sleeve 5. Rotate the locking sleeve 5 to screw the screw 11 into the locking sleeve 5 and lock it. Then, use bolts to pass through the through hole 13 and screw them into the screw hole 7 to complete the fixing of the adjusting plate 8, thereby completing the installation and fixing of the combiner box body 2. When disassembling, remove the fixing of the adjusting plate 8, turn the locking sleeve 5 to unscrew the screw 11 out of the locking sleeve 5, and the combiner box body 2 can be removed from the mounting plate 6 to complete the disassembly.
[0029] In this embodiment, the top and bottom of the adjustment plate 8 are provided with fixing plates 12, and the surface of the fixing plates 12 is provided with through holes 13. The adjustment plate 8 can be fixed by inserting bolts through the through holes 13 and screwing them into the screw holes 7.
[0030] In this embodiment, each lead screw 9 is provided with a rotating block 14 at its bottom end, and the lead screw 9 is rotated by rotating the rotating block 14.
[0031] In this embodiment, mounting blocks 15 are provided at the top and bottom of both sides of the mounting plate 6. Mounting holes 16 are provided on the surface of the mounting blocks 15. Bolts or expansion screws are inserted into the mounting holes 16 to fix the mounting blocks 15 in the wall, thereby completing the installation and fixing of the mounting plate 6.
[0032] In this embodiment, the mounting plate 6 is provided with a support plate 17 at its bottom, which supports the junction box body 2.
[0033] In this embodiment, both the rotating block 14 and the locking sleeve 5 are provided with anti-slip grooves. The anti-slip grooves increase the surface friction between the rotating block 14 and the locking sleeve 5, so that the operator will not slip when rotating the rotating block 14 and the locking sleeve 5.
[0034] In this embodiment, the internal threads of the fixing block 10 at the top and the fixing block 10 at the bottom of the lead screw 9 are arranged in opposite directions. This structure allows the two fixing blocks 10 on the lead screw 9 to move closer to each other or further away from each other when the lead screw 9 rotates.
[0035] The wall-mounted photovoltaic combiner box mounting bracket of this utility model has common mechanical installation methods, connection methods or setting methods, and can be implemented as long as it can achieve its beneficial effect.
