This problem is more prominent when the photovoltaic array layout needs to be adjusted frequently or when facing complex terrain conditions. Therefore, it is particularly urgent to design a photovoltaic combiner box bracket that can flexibly adapt to various inclination adjustments and is easy to install and maintain.

When the waterproof cylinder 3 is driven, the push plate 4 will be pushed to move horizontally in the recessed part of the base 1. When the push plate 4 moves horizontally, it can be linked to the outer end of the mounting frame 2 through the linkage rod 5 to quickly adjust the inclination angle of the junction box on the mounting frame 2, and cooperate with the photovoltaic panel to flexibly adjust the sunlight receiving angle. This structural design realizes the full range of inclination adjustment capabilities from completely flat to nearly vertical, and the mounting frame 2 can be folded and stored when not in use, saving space and facilitating transportation and storage. At the same time, the support rod 6 can be adjusted to a suitable left and right inclination angle on both sides of the base 1 to support the support block 7 on the ground, so as to adjust according to different terrains. The contact surface is smoothed to ensure that it can be firmly supported on uneven ground, thereby improving the adaptability of the device and satisfying the optimal configuration and efficient operation of the photovoltaic system. The outer walls of both sides of the base 1 are welded with fixed blocks 11, and the upper end of the support rod 6 is provided with a rotating rod 12 that is movably inserted into the solid block 11. A circular ring 13 is welded and fixed to the outer side of the connection between the solid block 11 and the rotating rod 12, and a locking bolt 14 is inserted into the outer end of the rotating rod 12 through a screw sleeve, and a plurality of threaded holes that match the structure of the locking bolt 14 are arranged around the inner wall of the circular ring 13. The support rod 6 of this structure can be rotated on the solid block 11 through the rotating rod 12 to adjust the left and right inclination angles, and when the support rod 6 and the support block 7 are adjusted to a suitable angle, the locking bolt 14 can be rotated in the screw sleeve at the outer end of the rotating rod 12 The guide block 8 is welded and fixed at the bottom of the push strip plate 4, and a guide groove matching the guide block 8 structure is provided on the bottom wall of the recessed portion of the base 1. The push strip plate 4 of this structure will drive the guide block 8 to slide in the guide groove on the bottom wall of the recessed portion of the base 1 when it moves horizontally, so as to improve the stability of the push strip plate 4 when it moves, which is also conducive to improving the stability when adjusting the inclination angle of the mounting frame 2. The bottom of the outer end of the mounting frame 2 is symmetrically welded and fixed with a card column 9, and the inner walls on both sides of the outer end of the recessed portion of the base 1 are provided with a card sleeve 10 matching the card column 9 structure. The card sleeve 10 is made of soft rubber.When the mounting frame 2 of this structure is folded and stored at the top of the base 1, the clamping column 9 can be driven to clamp inside the clamping sleeve 10 to ensure the stability of the mounting frame 2 when folded, which is more convenient for transportation and transfer. An assembly groove is provided on the top of the mounting frame 2, and guide frames 22 are provided on the inner walls of both sides of the mounting groove of the mounting frame 2, and brackets 21 are symmetrically connected between the guide frames 22. The two ends of the bracket 21 are slidably connected to the guide frames 22 and fixed by screws, and the outside of the bracket 21 is connected to the mounting ears 23 through a movable sleeve. There are two mounting ears 23 on each bracket 21.

In this way, the mounting ears 23 can be adjusted to different positions to cooperate with the installation of photovoltaic junction boxes of different specifications and sizes, and the versatility is higher.

[0018] Working principle: When using the foldable tilt adjustment structure, first move the base 1 to a suitable use position through the rollers at the bottom, and then install the photovoltaic junction box in the assembly groove on the top of the mounting frame 2. The mounting frame 2 can adjust the positions of the two brackets 21 for the photovoltaic junction box through the guide frame 22 respectively, and the mounting ears 23 can also slide and adjust the positions on the brackets 21 through the movable sleeves until the four mounting ears 23 are adjusted to the position suitable for installing the photovoltaic junction box and then fixedly installed. When the photovoltaic junction box is installed and used, if the tilt angle needs to be adjusted in conjunction with the photovoltaic panel, start the waterproof cylinder 3. When the waterproof cylinder 3 is driven, it will push the push plate 4 to move horizontally in the recessed part of the base 1. When the push plate 4 moves horizontally, it will drive the guide plate 4 to move horizontally. The block 8 slides in the guide groove on the bottom wall of the recessed portion of the base 1, and when the push strip plate 4 moves horizontally, it will be linked to the outer end of the mounting frame 2 through the linkage rod 5. After the outer end of the mounting frame 2 is subjected to force, it can be converted to different inclination angles on the top of the base 1. At the same time, if the base 1 is placed on an uneven ground, the support rod 6 can be rotated on the solid block 11 through the rotating rod 12 to adjust the left and right inclination angles. When the support rod 6 and the support block 7 are adjusted to a suitable angle, the locking bolt 14 can be rotated in the threaded sleeve at the outer end of the rotating rod 12 and fixed in the corresponding threaded hole on the inner wall of the ring 13. After the rotating rod 12 is limited, the inclination angle of the support rod 6 can be locked synchronously, so that the support rod 6 and the support block 7 can be supported more stably, thereby completing a series of tasks.
