[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figures 1-6 This utility model discloses a combined bracket for photovoltaic and metal roofing, including a roof metal frame 1 and a roof 2 disposed above the roof metal frame 1, and also includes a base fixing assembly 3, an angle adjustment assembly 4, a bracket assembly 5, and a photovoltaic module 6, wherein: The roof 2 is located between the base fixing component 3 and the angle adjustment component 4, and the bracket component 5 is snapped into the base fixing component 3; Please refer to the appendix. Figure 3 as well as Figure 4 The base fixing assembly 3 includes a base 31, a clamping plate 32, a pressing plate 33 and an elastic element. The clamping plate 32 is provided in several groups and is symmetrically arranged. The base 31 is fixed to the top of the clamping plate 32 by bolts. The clamping plate 32 is welded to the bottom of the pressing plate 33. The pressing plates 33 are symmetrically arranged and interlocked with each other. Please refer to the appendix. Figure 5 The angle adjustment component 4 includes an adjustment cylinder 41, a rotating screw 42, a sealing ring 43, and a tripod support. The bottom end of the adjustment cylinder 41 is threaded and passes through the roof 2 and the base 31. The sealing ring 43 is nested on the outside of the adjustment cylinder 41 and fixed to the roof 2 and the base 31 by bolts. The rotating screw 42 is fitted into the adjustment cylinder 41 and rotates in a spiral manner. Specifically, by rotating the rotating screw 42, relative displacement occurs between it and the adjustment cylinder 41, thereby driving the tripod support to move up and down.

[0017] The elastic element includes a rotating shaft 34 and a torsion spring 35. The rotating shaft 34 passes through the middle of the clamping plate 32 and is rotatably engaged. The torsion spring 35 is nested on the outside of the rotating shaft 34 and its two ends abut against the sides of the clamping plate 32.

[0018] The tripod support includes a support horizontal plate 44, a support side plate 45, and an adjusting rod 46. The support side plate 45 is symmetrically welded to the bottom of the support horizontal plate 44 and arranged in a triangular configuration. The support horizontal plate 44 is penetrated by the top of the rotating screw 42 and rotates in engagement. Specifically, the support horizontal plate 44 and the rotating screw 42 rotate in engagement. As the rotating screw 42 moves up and down, it in turn pushes the adjusting base 61 up and down through the adjusting rod 46. By adjusting the height of the two ends of the adjusting base 61, the tilt angle can be changed. The triangular structure formed by the support side plate 45 and the support horizontal plate 44 makes the support of the adjusting base 61 more stable.

[0019] In this embodiment, the clamping plate 32 forms an openable structure through the cooperation of the rotating shaft 34 and the torsion spring 35. During installation, the clamping plate 32 is opened by external force and fits onto the purlin 51. Then, the torsion spring 35 provides a restoring force to close the clamping plate 32. The base 31 is then fixed to the top of the clamping plate with bolts, thereby firmly installing the base fixing assembly 3 on the bracket assembly 5. Then, the roof 2 is stacked on the spliced ​​base 31, and the adjusting tube 41 is inserted between the base and the roof 2 and fixed with bolts. With the help of the sealing ring 43, waterproof sealing is achieved, which greatly reduces the number of holes to be drilled on the metal roof, avoids damage to the waterproof structure, reduces the risk of water leakage, and at the same time, the installation is quick and efficient. Example

[0020] Based on the above embodiment 1, please refer to the appendix. Figure 2 as well as Figure 6 The photovoltaic module 6 includes a base frame 61, on which a photovoltaic panel 62 is fixed by bolts. The bottom of the base frame 61 is fitted with the top of an adjusting rod 46 and rotates in cooperation with it. The bottom of the adjusting rod 46 is fitted with a supporting horizontal plate 44 and slides in cooperation with it. Specifically, the adjusting rod 46 can rotate with the base frame 61 when the angle of the base frame 61 changes, and at the same time, it can adapt to the change in the vertical projection distance of the base frame 61 caused by the change in angle by sliding on the supporting horizontal plate 44.

[0021] The roof metal frame 1 is provided with a crossbeam 11, and the support assembly 5 includes purlins 51. A number of purlins 51 are provided along the length of the crossbeam 11 and are fixed at equal intervals on the crossbeam 11.

[0022] The purlin 51 is provided with an L-shaped reinforcing plate 52 on its side, and the L-shaped reinforcing plate 52 is fixed to the crossbeam 11 and the purlin 51 by screws.

[0023] The purlin 51 has an I-shaped structure and is fitted into the bottom of the clamping plate 32.

[0024] In this embodiment, the purlins 51 in the bracket assembly 5 are fixed at equal intervals along the length of the crossbeam 11 of the roof metal frame 1 to form a support structure. The purlins 51 are I-shaped and are fitted into the bottom of the clamping plate 32, which further enhances the connection stability with the base fixing assembly. At the same time, the L-shaped reinforcing plate 52 is fixed to the crossbeam 11 and the purlins 51 by screws, which improves the connection strength between the purlins and the crossbeam, so that the entire bracket assembly 5 can stably support the photovoltaic module 6 and the angle adjustment assembly 4 above.

[0025] The working principle and usage process of this utility model are as follows: During installation, first check whether the structure of the roof metal frame 1, such as the crossbeam 11, is stable. Prepare the various components of the combined bracket. Then, fix the purlin 51 to the crossbeam 11 with bolts and reinforce it with L-shaped reinforcing plate 52. Place the clamp 32 of the base fixing component 3 on the purlin 51 and align the clamp 32 with the purlin 51. Manually squeeze the pressing plate 33 to open the clamp 32. After releasing, the torsion spring 35 drives the clamp 32 to close, so that it fits into the purlin 51. Then, fix the top of the base 31 and the clamp 32 with bolts to complete the installation of the base fixing component on the metal roof. The roof 2 is then stacked on the spliced ​​base 31, and the adjusting tube 41 is inserted between the base and the roof 2 and fixed with bolts. With the help of the sealing ring 43, waterproof sealing is achieved, which greatly reduces the number of holes to be drilled on the metal roof, avoids damage to the waterproof structure, reduces the risk of water leakage, and the installation is quick and efficient. Subsequently, the rotating screw 42 of the angle adjustment component 4 is inserted into the adjustment cylinder 41, forming a helical rotational engagement with the adjustment cylinder 41. The photovoltaic panel 62 is then fixed onto the base frame 61, completing the installation. When the rotating screw 42 is rotated, the rotating screw 42 and the adjustment cylinder 41 undergo relative displacement. The support plate 44 of the tripod support component rotates in engagement with the rotating screw 42. As the rotating screw 42 moves up and down, it in turn pushes the adjustment base frame 61 up and down through the adjustment rod 46. By adjusting the height of both ends of the adjustment base frame 61, its tilt angle is changed, thereby achieving flexible adjustment of the photovoltaic module installation angle according to the actual sunlight and roof conditions in different regions, greatly improving installation efficiency.
