[0002] Adjusting the angle of photovoltaic (PV) mounting systems is a common technique. However, existing adjustable-angle PV mounting systems generally use a linkage system for connection. The linkage structure has poor stability and is not suitable for PV mounting systems with certain strength requirements. Therefore, there is a great need to provide a PV mounting system with high strength and certain limiting functions, and extensive research has been conducted on this topic. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an adjustable angle photovoltaic bracket, which can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: An adjustable angle photovoltaic bracket of this utility model includes a body, two columns are provided on the top of the body, and a connecting shaft is rotatably provided between the columns. The feature is that a swing block is rotatably provided on the outside of the connecting shaft, a mounting bracket is provided on the top of the swing block, two sliding grooves are provided at the bottom of the swing block, and a snap-fit ​​groove is provided at the top of the sliding grooves. A threaded shaft that moves up and down is provided inside the body, and a snap-fit ​​assembly is provided between the threaded shaft and the sliding grooves and the snap-fit ​​groove. A moving assembly that causes the threaded shaft to move up and down is provided inside the body.

[0005] In a further technical solution, the swing block is provided with an inner hole, and the inner hole is rotatably connected to the connecting shaft.

[0006] In a further technical solution, a limiting guide groove is provided inside the swing block, a base is provided on the top of the column, a limiting rod is fixedly provided between the bases, and the limiting rod passes through the limiting guide groove.

[0007] In a further technical solution, the base is detachably connected to the top of the column.

[0008] A further technical solution includes a snap-fit ​​assembly comprising a movable rod disposed at the top of the threaded shaft, the movable rod being slidably connected to the snap-fit ​​groove and the sliding groove.

[0009] A further technical solution includes a sliding plate disposed at the bottom of the threaded shaft, a sliding structure for guiding the sliding plate to slide within the body, and a lifting structure for moving the threaded shaft up and down within the body.

[0010] A further technical solution includes a sliding structure comprising a plurality of guide rods disposed within the body of the machine, the guide rods being slidably connected to the sliding plate.

[0011] A further technical solution includes a lifting structure comprising a rotatable internally threaded sleeve disposed within the machine body, a threaded shaft passing through the internally threaded sleeve, the threaded shaft being threadedly connected to the internally threaded sleeve, a rotating shaft being rotatably disposed within the machine body, a driving gear being disposed at the bottom of the rotating shaft, and a driven gear being disposed on the outer surface of the internally threaded sleeve, the driven gear being meshed with the driving gear.

[0012] In a further technical solution, a rotating wheel is provided at the top of the rotating shaft.

[0013] The beneficial effects of this utility model are: First, by setting a limiting rod between the seats, and passing the limiting rod through the limiting guide groove, the swing block can be restricted to swinging at a certain angle after rotating around the connecting shaft.

[0014] Second, when the moving rod on one side of the threaded shaft engages with the locking groove, the swing block and the mounting bracket will be locked in place while maintaining a vertical orientation, preventing the swing block and the mounting bracket from flipping over.

[0015] Third, by disengaging from the moving rod after the threaded shaft and the locking groove move downwards, and then manually rotating the swing block, the swing block can be made to swing to both sides. Then, by using the threaded shaft and the locking groove to continue moving downwards, it can slide and engage with the sliding groove, allowing the swing block to swing further as the threaded shaft and the locking groove move downwards. When the threaded shaft and the locking groove stop moving, the swing block is locked and cannot swing. This structural design greatly improves the structural robustness and enables the swing block to maintain good fixation performance after swinging. Attached Figure Description

Figure 1 The projected directions are consistent in all directions (up, down, left, right, front, back). This utility model provides an adjustable angle photovoltaic bracket, including a body 17. Two columns 14 are provided on the top of the body 17. A connecting shaft 25 is rotatably provided between the columns 14. A swing block 12 is rotatably provided on the outside of the connecting shaft 25. A mounting bracket 11 is provided on the top of the swing block 12. Two sliding grooves 31 are provided at the bottom of the swing block 12. A snap-fit ​​groove 32 is provided at the top of the sliding grooves 31. A threaded shaft 15 that moves up and down is provided inside the body 17. A snap-fit ​​assembly is provided between the threaded shaft 15 and the sliding grooves 31 and the snap-fit ​​groove 32. A moving assembly that allows the threaded shaft 15 to move up and down is provided inside the body 17.

[0023] Advantageously, the swing block 12 is provided with an inner hole 42, which is rotatably connected to the connecting shaft 25.

[0024] Advantageously, the swing block 12 is provided with a limiting guide groove 43, the top of the column 14 is provided with a seat 13, the seat 13 is detachably connected to the top of the column 14, and a limiting rod 41 is fixedly provided between the seats 13. The limiting rod 41 passes through the limiting guide groove 43 and limits the limiting guide groove 43.

[0025] Advantageously, the snap-fit ​​assembly includes a movable rod 33 disposed on the top of the threaded shaft 15, the movable rod 33 moving within the snap-fit ​​groove 32 and the sliding groove 31, the movable rod 33 being slidably engaged with the snap-fit ​​groove 32 and the sliding groove 31.

[0026] Advantageously, the moving component includes a sliding plate 18 disposed at the bottom of the threaded shaft 15, a sliding structure for guiding the sliding plate 18 is disposed inside the body 17, and a lifting structure for causing the threaded shaft 15 to move up and down is also disposed inside the body 17.

[0027] Advantageously, the sliding structure includes a plurality of guide rods 21 disposed within the body 17, the guide rods 21 being slidably connected to the sliding plate 18.

[0028] Advantageously, the lifting structure includes a rotatable internally threaded sleeve 16 disposed within the body 17, a threaded shaft 15 passing through the internally threaded sleeve 16, the threaded shaft 15 and the internally threaded sleeve 16 being threadedly connected, a rotating shaft 23 being rotatably disposed within the body 17, a driving gear 22 being disposed at the bottom of the rotating shaft 23, and a driven gear 19 being disposed on the outer surface of the internally threaded sleeve 16, the driven gear 19 being meshed with the driving gear 22.

[0029] Advantageously, a rotating wheel 24 is provided on the top of the rotating shaft 23.

[0030] In practical use, a photovoltaic bracket is installed on one side of the mounting frame 11. In the initial state, the moving rod 33 is located at the top and is fixedly engaged with the locking groove 32, so that the swing block 12 cannot rotate around the connecting shaft 25.

[0031] When adjusting the angle of the swing block 12 and the mounting bracket 11, after rotating the rotating wheel 24, the driving gear 22 is driven to rotate through the rotating shaft 23. The driving gear 22 is engaged with the driven gear 19, causing the internal threaded sleeve 16 to rotate. After the threaded shaft 15 is threadedly connected to the internal threaded sleeve 16, the sliding plate 18 is slidably limited by the guide rod 21, causing the threaded shaft 15 to drive the moving rod 33 to move downward.

[0032] Before the moving rod 33 disengages from the locking groove 32, the operator manually tilts the swing block 12 according to the desired swing position. Then, the rotating wheel 24 is rotated to make the moving rod 33 slide against the bottom of the slide groove 31. As the threaded shaft 15 and the moving rod 33 continue to move downward, the moving rod 33 continues to slide against the end wall of the slide groove 31. After rotating the wheel 24, the moving rod 33 moves downward and further tilts the swing block 12. When the rotating wheel 24 is not rotated, the moving rod 33 is locked to the slide groove 31. When the swing block 12 is to rotate, it will be locked and resisted by the moving rod 33 to prevent the swing block 12 from overturning.
