[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Referring to Figures 1 and 2, a sealed joint structure for roof profiles is shown. The sealed joint structure includes a sealing component 1 and at least two profile plates 2. The profile plates 2 are aluminum profiles. The profile plates 2 are square in shape, with straight edges. The adjacent edges of the two profile plates 2 are joined to form a straight joint.

[0036] The two profile plates 2 include a first card plate 31 and a second card plate 32 at the joint, that is, one of the profile plates 2 includes a first card plate 31 at the joint, and the other profile plate 2 includes a second card plate 32 at the joint. The first card plate 31 is bent to form a first card groove 311 at the bend, and the second card plate 32 is bent to form a second card groove 321 at the bend. In this embodiment, the opening of the first card groove 311 faces one side of the joint, and the opening of the second card groove 321 faces the other side of the joint. The sealing component 1 is provided on at least one of the profile plates 2, and the sealing component 1 extends along the joint of the two profile plates 2. When the two profile plates 2 are spliced ​​together, the end 312 of the first clamping plate 31 is buckled into the second clamping groove 321, and the end 322 of the second clamping plate 32 is buckled into the first clamping groove 311. The end 312 of the first clamping plate 31 and the end 322 of the second clamping plate 32 are bent and deformed along the thickness direction so that the first clamping plate 31 and the second clamping plate 32 are clamped to each other to form a stacking structure 33. The gap 34 between the splicing parts is located in the stacking structure 33. The sealing component 1 is arranged at the entrance 341 of the gap 34. The stacking structure 33 presses against the sealing component 1 to seal the entrance 341 of the gap 34.

[0037] The end 312 of the first clamping plate 31 is buckled into the opening of the second clamping slot 321, and the end 322 of the second clamping plate 32 is buckled into the opening of the first clamping slot 311. When the two profile plates 2 are subjected to an outward pulling force perpendicular to the joint, the first clamping plate 31 is fastened to the second clamping slot 321, and the second clamping plate 32 is fastened to the first clamping slot 311. After the buckling is completed, the end 312 of the first clamp 31 and the end 322 of the second clamp 32 can be pressed together in the thickness direction, so that the end 312 of the first clamp 31 is close to the starting end 313 of the first clamp 31, and the end 322 of the second clamp 32 is close to the starting end 323 of the second clamp 32, until the end 322 of the second clamp 32 and the starting end 323 of the second clamp 32 are attached to the upper and lower side surfaces of the end 312 of the first clamp 31 and the end 312 of the first clamp 31 and the starting end 313 of the first clamp 31 are attached to the upper and lower side surfaces of the end 322 of the second clamp 32. At this time, the first and second clips 31, 32 form a stacked structure 33, such that a gap 34 between the joints extends along an S-shape within the stacked structure 33. The sealing component 1 is disposed on one of the profile plates 2 and extends along the joint. The sealing component 1 is arranged at the entrance 341 of the gap 34. The stacked structure 33 presses against the sealing component 1 to seal the gap 34. The bending deformation between the first and second clips 31, 32 causes the gap 34 to extend in a meandering manner within the stacked structure 33. The sealing component 1 is also disposed at the entrance 341 of the gap 34. The sealing component 1 ensures a waterproof seal at the entrance 341. Furthermore, because the stacked structure 33 directly presses against the sealing component 1, the connection is more stable and reliable.

[0038] In this embodiment, the end 312 of the first clamping plate 31 is bent downward to form the first clamping slot 311, and the end 322 of the second clamping plate 32 is bent upward to form the second clamping slot 321. The upward-facing surface of the starting end 323 of the second clamping plate 32 further includes an engagement groove 324, and the sealing component 1 is disposed within the engagement groove 324. The sealing component 1 is an elastic sealing strip; when disposed within the engagement groove 324, the elastic sealing strip at least partially extends outside the engagement groove 324. The first clamping plate 31, which is bent and flattened along the thickness direction, presses against the elastic sealing strip to secure it.

[0039] Referring to Figures 3, 4, and 5, the present invention also provides a photovoltaic roof profile 4, comprising a first profile plate 41, a second profile plate 42, and a third profile plate 43. The second profile plate 42 is spliced ​​between the first profile plate 41 and the third profile plate 43 to form a bearing plane 44, and the bearing plane 44 is used to bear the photovoltaic panel 5; the adjacent first profile plates 41, the second profile plates 42, and the third profile plates 43 are spliced ​​and connected by the sealed splicing structure. Specifically, the left side of the second profile plate 42 includes the second clip 32, the right side of the second profile plate 42 includes the first clip 31, the right side of the first profile plate 41 includes the first clip 31, and the left side of the third profile plate 43 includes the second clip 32. The connection between the three can be directly referred to the sealed splicing structure mentioned above, and will not be repeated here.

[0040] The first profile plate 41 , the second profile plate 42 and the third profile plate 43 are sequentially buckled and connected along the width direction, so that they are more stable when subjected to a pulling force along the width direction.

[0041] The end 312 of the first clamping plate 31 is bent downward to form the first clamping groove 311, and the end 322 of the second clamping plate 32 is bent upward to form the second clamping groove 321. The upward side of the starting end 323 of the second clamping plate 32 also includes an interlocking groove 324, and the sealing component 1 is arranged in the interlocking groove 324; the sealing component 1 is an elastic sealing strip; when the elastic sealing strip is arranged in the interlocking groove 324, at least part of it extends out of the interlocking groove 324, and the first clamping plate 31 bent and flattened along the thickness direction is pressed against the elastic sealing strip to fix the elastic sealing strip.

[0042] In this embodiment, the left side of the first profile plate 41 includes a side splicing structure 45, and the right side of the third profile plate 43 includes a drainage trough structure 46; the side splicing structure 45 includes a third card slot 451 and a fourth card slot 452 arranged at intervals along the width direction, and the drainage trough structure 46 includes a third card plate 461 and a fourth card plate 462 arranged at intervals along the width direction, and the third card slot 451 and the fourth card slot 452 are oriented on the same side along the width direction; when at least two photovoltaic roof profiles 4 are spliced ​​along the width direction, the third card plate 461 and the fourth card plate 462 move along the width direction to be respectively embedded in the third card slot 451 and the fourth card slot 452.

[0043] 6, 7, 8, 9, and 10, in this embodiment, the first end of the photovoltaic roof profile 4 along the length direction includes an upwardly folded bending plate 47, and the second end of the photovoltaic roof profile 4 along the length direction forms a clearance space 48 at the position of the drainage trough structure 46; when two photovoltaic roof profiles 4 are connected to each other along the length direction, the second end of the first photovoltaic roof profile 4 along the length direction is overlapped above the first end of the second photovoltaic roof profile 4 along the length direction, and the bending plate 47 is supported below the first photovoltaic roof profile 4, and the drainage trough structure 46 of the first photovoltaic roof profile 4 corresponds to entering the clearance space 48 of the second photovoltaic roof profile; and a plug 49 is also included, and the plug 49 is plugged on the second end of the photovoltaic roof profile 4 along the length direction.
